mtd kernel driver hacks? - Droid Eris Q&A, Help & Troubleshooting

Hi devs,
Are you aware of any work (for other Android phones, for instance), where an altered mtd kernel driver was used to allow (raw) root access anyplace within flash memory? (For example, maybe a raw pseudo-partition which overlaps all the other partitions?) The stock mtd driver creates devices in the kernel device tree only for specific partition slices (boot, system, recovery, data, cache) - for obvious safety and security reasons.
After all these months, I stumbled across this tonight
Code:
C:\foo>fastboot oem listpartition
...

I had never seen references in the Eris forums to the misc3, mfg, sp1, misc2, or mfg2 partitions - I suppose one or more are for boot images. Maybe interesting to boot a kernel image that had access to them, and have a peek at them?

You are venturing into an area that is slightly beyond my current level of understanding. (Although we can all learn more.)
Is this even close to what you are looking for?
http://forum.xda-developers.com/showthread.php?t=754805
I'm thinking not, since they appear to be resizing the existing partitions, which doesn't seem to be quite what you are looking for.

I was asking about this a while back to see if anyone was able to get read access to the splash1 (i'm guessing sp1) partition so we could dump the REAL original splash screen for people that needed to go back to full stock. This was basically the only thing that is left out of going to stock since the "original" boot image that I had used for the android skateboards in my post about changing the boot logo was just a resized version I found online somewhere which is slightly bigger than the original if you look closely. I had some info laying around somewhere but it was definitely something about people modifying the mtd drivers in the kernel to get this done.
Without the modified drivers there is no way to do a FULL nand dump at this point.

Well, I'd seen that before - but THANK YOU - your post encouraged me to do a better job of searching, and I came up with this:

[SIZE=+2]Awesome![/SIZE] It appears that no mtd kernel hack is needed - as long the Eris kernels we are using accept those parameters (obviously, a little additional work is needed to get the offsets correct for the Eris).
I knew that partitions could be resized - but I wasn't aware that you could add new partition definitions. If it works for the Eris, then cool. (I have to say - the G1/G2/Hero devs surely have turned over a lot of stones that have helped us.)

Mohahahhahahahaaha (rubbing hands together deviously). I smell either some interesting development or at least some interesting information coming out of this.

It's working.
More details later.

Flash Memory Map for the Eris:
Code:
PARTITION START END SIZE(1KB) SIZE(128KB) NOTES
radio 0x00000000 - 0x02980000 42,496 332 (3)
- gap! - 0x02980000 - 0x029a0000 128 1 (3)
hboot 0x029a0000 - 0x02a60000 768 6 (2)
misc3 0x02a60000 - 0x02aa0000 256 2 (5)
mfg 0x02aa0000 - 0x02ae0000 256 2 (6)
sp1 0x02ae0000 - 0x02ba0000 768 6 (4)
misc2 0x02ba0000 - 0x02c00000 384 3 (4)
mfg2 0x02c00000 - 0x02c60000 384 3 (4)
recovery 0x02c60000 - 0x03160000 5,120 40
boot 0x03160000 - 0x033e0000 2,560 20
system 0x033e0000 - 0x0dde0000 174,080 1360
cache 0x0dde0000 - 0x15fe0000 133,120 1040
userdata 0x15fe0000 - 0x1ff60000 163,328 1276
misc 0x1ff60000 - 0x20000000 640 5
( You can verify the above on your own phone with a combination of examining /proc/mtd, "dmesg" output immediately after the boot, and output of "fastboot oem listpartition" )
(1) Note all partitions are aligned to a 128-KB boundary (0x20000 - 18 bits)
Presumably this is why "fastboot oem listpartition" reports sizes in this unit
(2) Hboot images from HTC for the Eris have always been exactly 512 KB. Slack space is here,
but I found nothing but 0xFF's in the slack area.
(3) Attempting to dump the from this partition produces many, many error messages of the form:
mtd: MEMGETBADBLOCK returned -1 at 0x02940000 (errno=5)
mtd: MEMGETBADBLOCK returned -1 at 0x02960000 (errno=5)
(4) On my phone, dumps of partitions "sp1", "mfg2" and "misc2" produced un-interesting data blobs: all 0xFF's
Note that I have never flashed a custom boot splashscreen.
(5) Nearly "empty" - bytes not 0x00 or 0xFF are all string data (including CID)
(6) Contains "interesting" string data (including handset ID, manufacturing date, etc) and other binary data. Performing interesting handset operations and then recapturing a partition dump (before/after) and performing a binary diff could reveal strategic locations.
[SIZE=+1]HOW-TO[/SIZE]
Most people have absolutely no business doing this - you have been warned.
Under no circumstances should you hand-type any of these addresses; a simple typo could lead to disaster.
Code:
fastboot -c " mtdparts=msm_nand:[email protected](misc),[email protected](recovery),[email protected](boot),[email protected](system),[email protected](cache),[email protected](userdata) " boot recovery-RA-Eris-v1.6.2.img
will produce the standard kernel partition mappings. Note the leading and trailing spaces in the quoted string - and that the order of appearance is critically important
You may append one or more** of the following, separated with commas as shown in the above (standard mapping) command.
[email protected](radio)
[email protected](hboot)
[email protected](misc3)
[email protected](mfg)
[email protected](sp1)
[email protected](misc2)
[email protected](mfg2)
** I performed individual boots adding only one non-standard partition, and can not guarantee that a disaster will not result if you try to append more than one - or all of them - in one boot.
You can verify the additional partitions have been kanged into the kernel's device tree with
adb shell cat /proc/mtd
and may dump individual partitions via the command "dump_image" (provided by Amon_RA in /sbin), as in the following example:
mount /sdcard
dump_image mfg /sdcard/part.mfg.img
bftb0

If you just want to dump a specific Eris flash memory partition(s) off your phone, there is an even easier method. (Doh!)
Prerequisites:
- 1.49.2000 S-OFF bootloader is installed on your Eris.
- working device drivers on PC and fastboot utility
Steps:
1) Connect via USB to your PC and put phone in FASTBOOT mode (Power up with Send+End)
2) Get the partition names listing using
Code:
fastboot oem listpartition
3) Using the following fastboot syntax, plug in the desired partition name (PNAME):
Code:
fastboot oem saveprt2sd PNAME -n PNAME.bin -a
for example, the "sp1" partition:
Code:
$ fastboot oem saveprt2sd sp1 -n sp1.bin -a
... INFOSaveImageToSD partition file name:sp1
INFOSaveImageToSD output file name:sp1.bin
INFOCmd5 CMD_TIMEOUT

How to use nvflash to flash clean system?

Hallo, now that we have the tool, how can we make a full clean system restore, because i did, wipe my prime, and i cannot flash via Fastboot then it came up with this message

if im not mistaken you have to flash via apx mode, to enter apx mode begin booting your tablet like normal, then while it is attempting to boot hold both the powerbutton and up vol key this will send you into apx mode where the screen just goes blank.
Next type the following command
wheelie --blob blob.bin to boot strap into nvflash
now proceed as you normally would with nvflash
(i believe the commands may be slightly altered in this version of nvflash so you may want to run nvflash help to make sure you are using the right commands)

Thanks for the quick answer.
I got to the nvflash part, but from here i don't know what commands i should use to flash my ROM to my prime.
I think maybe that my partitions tables is broken, is there a way to fix that, because every time i try to format whit Fastboot i get this message
Code:

I just realized that you are trying to flash .blob files, with the bootloader that comes with the NVflash mod you must use .img files you will need to get blob unpacking tools from Android Root to unpack blob files then flash them partition by partition

Thank you very much, I managed to flash all my partition in Fastboot now, when i unpacked them with blobunpack, my prime is back alive thanks to you
People have to remember they are no longer using asus bootloader/fastboot, when they AndroidRoot.

Some of you may have noticed that i did not start the original thread with a question, I did something my mentor taught me at around 9 years old but didn't put into good use until much later in life.
The tip is write things down as a question for yourself, in the writing process you get to pass the information past the part of your brain that interprets information, virtual sounding board, before posting as a question for others.

Hi All
As i mentioned on this thread http://forum.xda-developers.com/showthread.php?p=32231827#post32231827 i will be attempting to come up with a home grown debrick solution for a SHV-E160L samsung note from korea.
I will use the forum to document what i am doing, i am very new to this so correct me please if i am wrong. I have never done Android dev work at any time but i have a very good understanding of the logic behind it all. `
Things i Have :-
Phone ( SHV-E160L)
bus pirate v3 with jtag firmware
openocd compiled on ubuntu and centos 6
smd jtag adapter and relay wire ( magnetic wire)
things i still need :-
openocd target config file for MSM8660 Snapdragon cpu (and a better understanding of eMMC access, how to load boot loaders either into ram or eMMC or trigger fail over boot to sc-card, USB via software or X0M/Boot pins)
assembled jtag (it's the smallest soldering i've ever seen)
.PIT file for 32GB model (if someone could pull the .PIT file from a working unit I would be happy, specify your radio/kernel versions when uploading)
micro fine solder iron tip and 20w iron (i've got 60w but too high for this type of work)
Does anyone have a idea of the SD-CARD partition layout, files for snapdragon devices, google has given me much for other devices but not a snapdragon .
Another question, I've used the USB jig to trigger 301K mode USB-Factory and seen no activity in dmesg for usb devices, i've yet to try windows, does windows/linux behave in a different way when it comes to usb , as in windows see's the qualcom usb mode but not linux ? does the usb client device always start the comms?
using the 615K usb jig i get nothing too, no pbl message from samsung (hence i am led to think is's the pbl/sbl thats damaged)
My understanding up boot is as follows
iROM code
This loads basic settings to boot the PBL (iROM is in rom) the PBL is loaded into radio(modem) cpu and then loads the SBL(s)
PBL/SBL stored in eMMC at address ????? (need to document the address for the masked access to eMMC and jtag/openocd access unmasked access)
Once the SBL is loaded you with have the ODIN mode (USB/UART)
from what i can see of commercial JTAG boxes is the access the radio cpu via jtag, write a new PBL/SBL to the eMMC then halt/reset cpu which now loads the new bootloaders, (resurrect dead body)
The openocd TAP id for the cpu should be 0x105310E1 but thats a number i got from a riff box log, not any actual testing ( still need to solder the fine pitch connector)
Here is a log from a riff box, not sure if the address's are usable accross to opencd
Taken from gsm-forums:-

I did notice one thing, the riff box opens the serial port, i wonder if they load PBL+SBL into memory, reset the cpu, then using the serial connection activate download mode ? (like on the captive)
I also dont know how the cpu (jtag TAP id? ) and flash variables translate accross to openocd as ive not found a target config file yet ( or my searching is wrong)
in the full stock Firmware I was able to extract the .tar file which contained,
Code:
amss.bin <-- application cpu boot files ?
boot.img <-- kernel/initrd ramdrive
mdm.bin <-- modem cpu boot files
recovery.img <--- recovery image
system.img.ext4 <---- rest of the system applications
so i think we have the two cpu firmware/boot loaders in the .bin files, these bin files are just fat32 images, to access in ubuntu use
Code:
mount -o loop mdm.bin /mnt/mdmmountlocation
My guess is my first approach is getting the right PBL/SBL into the system and getting some feed back via uart, i have the jtag pinouts and further reserach says there is a UART2 on the jtag header, so when soldering up my jtag adapter i will include all pins if i can and sniff for serial logic, i happen to have a Open source logic sniffer, great tool as i do a lot of hacking into serial devices like scales and till printers .
back to topic.
When i do get to the jtag part at a minimum i should have access to the modem radio, afaik jtag devices connect in chains and most of the IC's that have jtag on the phones board all should link to the master device (i am thinking it's the modem cpu, no application) and that the Two cpu's share the eMMC memory some how, or it could be one cpu loads it into the other (it is connected via jtag down the chain) .
hopefully someone could correct me there.
Most of this is theory and my guess work, correct me if you find a mistake. most of the research is only over a few days too so i am far from finished there, does not help that most of the users speak a language that google translate just does not have a flair for.
Most of the info seems to suggest the modem cpu is the first inline so i decided to look further into the files there, notice the mdm.bin file is 23Mb, thats large, when mounted i notice the is a folder called 'image' ( amms.bin has folder called IMAGE , note the case difference, dont yet know whay)
in image folder we have :-
Code:
1.3M Sep 30 13:07 AMSS.MBN
35K Sep 30 13:07 DBL.MBN
2.2M Sep 30 13:07 DSP1.MBN
19M Sep 30 13:07 DSP2.MBN
40 Sep 30 13:07 EFS1.MBN
40 Sep 30 13:07 EFS2.MBN
40 Sep 30 13:07 EFS3.MBN
295K Sep 30 13:07 OSBL.MBN
Ah, i see amss.mbm , that must be the boot loader for the application cpu, DBL.MBM seems to be the PBL , OSBL.MBM could be the SBL
then there is the DSP/EFS files, I did do the command strings on all the files,
DBL.MBM does not have any text in the file that points to being able to do UART on boot, all text seems internal like pointers and references to the original build files e.g
Code:
D:\Q1LGT_MDM\MDM9600\modem_proc\core\boot\secboot2\dbl\target\mdm9x00\src\dbl_ddr.c
9x00B-SCAQSVZM-31613102
D:\Q1LGT_MDM\MDM9600\modem_proc\core\boot\secboot2\dbl\target\mdm9x00\src\dbl_sahara.c
but it also does contain data like this
Code:
auth_image
@[email protected]
@configure_hw
@flash_init
l0:eek:SBL
load_osbl_img
@DBL, Start
hw_init
so it looks more likley that dbl is first in the chain, it refers to loading osbl and configure hardware, i wonder if it means USB/UART at this stage or setting up ram and other GPIO's
in OSBL.MBM we have more interesting text
Code:
MbP?
Unable to attached to ChipInfo DAL

TOSHIBA
Flash: Failed to do initialization for probe!
ONFIx

Flash: Multi 2X page read not supported!

osbl_sahara_load_dsp2
osbl_sahara_load_ramfs1
osbl_sahara_load_ramfs2
osbl_sahara_load_ramfs3
smem_boot_init
so it is looking more and more like DBL then SBL which then loads all of the other parts , also if you notice EFS1/2/3 are all tiny 40byte files, now i see why, they are loaded as ram-drives, so i assume those file set out the basic EFS file system in the ram.
again from research the boot stages are often counted as 3, i am assuming the real first part is in rom of the cpu (is this what triggers the qualcom download mode ) that loads DBL from eMMC and chain loads SBL
Now looking around the riff forums i see the list the info in a different way
Code:
Partition 0
SBL1
SBL2
Partition 1
RPM
SBL3
eMMC APPSBoot
TZ
.PIT
Click to expand...
Click to collapse
TZ i think is Trusted Zone
RPM - Power manager ?
now how this translates to file name from full flash and to mmcblk0p1 partitions i have yet to find out, i still dont have a .PIT file from a 32gb model
More updates to come,

CPU Boot order updates
So my digging has taken me back round to some of me early searching which i forgot about , hardware level seems to support the qualcom usb mode, but it can be disabled by manufacturer, so even if you find a resistor to the BOOT_CONFIG GPIO and ground it , it still may not work, and you could toast your board. once the qfuse is gone for that track, the maker can now use the gpio for anything else, it no longer controls the iROM branch choice ( CPU:do i start usb first or last?), it my thinking that on the first board sent out by the designers for a final production run ( those first public devices) they keep the option open to print off DEV models by changing the resistors/value of while the hardware stays same, not to be confused with dev board, that is pin/track simlar but is used to design the software mainly, sometimes hardware debug but as you change the hardware between the dev platform and production this is less helpful, google new.intrinsyc.com and apq8060, they produce a dev board that is the same as the device we hold, but everything is broken out for testing so don't expect to see this left in a bar for you to e-bay.
EDIT:
Above I refer to a dev phone and dev board, these are SURF and FFA, FFA is form factor accurate and SURF is Subscriber Unit Reference.
Here is the link, http://forum.xda-developers.com/showthread.php?t=1856327
Now from what i see, it's the same(edit:simlar) X0M pin setup as other phones, ground the right pin, reverse boot order, but this maybe two pins in the snapdragon,

Simplified table:
Code:

0b00000 Emergency Boot from SDC3 (SD) followed by USB-HS
0b00001 SDC3 followed by SDC1 (eMMC)
0b00010 SDC3 followed by SDC2 (if used)
0b00011 SDC1 (eMMC)

So if 0b00000 is EM boot and the docs say the the two gpio's that control this (if qfuse not blown) are taken high then it's 0b00011, so grounding those two resistors should give us 0b00000 or EM boot, the cpu docs also say they are internally grounded, the schematic says the voltage goes throught a 10k resistor, so grounding that side of the resistor that 'goes' to the cpu should change the boot order, but before trying this out, remember if you get the live side of the resistor the is no resistor between your probe and ground, that full current, short, blown, no more johnny 5.
Have you managed to unbrick the E160L?

I think my E160L got a real brick today after I tried to flash a modified Rom downloaded from a Chinese forum. It can not be powered on after rebooting (installed successfully). I desperately need advice now on how to deal with it.

Do you have any backups like nandroid ? does the 3 button boot still work ?
Regards
Have you looked into using ort-jtag. It's only about $150 (USD).
I've been looking into this myself for low-level debugging/bootloader development on SGH-T959V and SGH-I717.
All three of these devices are supported by ort-jtag and have header connectors for the jtag pins.
So I'm also getting some of these from digi-key, and making a small receptacle, much like in AdamOutler's captivate bootloader development thread. (search for k-ww)
Again, ort-jtag does support the SHV-E160L. (search that link for SHV-E160L)

does any one want the dump that can reverse it ?
Dumps & execute address
I also need the help of other SHV-E160? owners, i need dumps from working phones, i managed to create a 8660_msimage.mbn and flashed it, but i was using i717 bootloaders and i dont think they will work, i need working dumps from working phones, starting with partition table layout, sbl1.mbn and sbl2.mbn
Does anyone know if the is is correct
SBL1 exec address 0x2A000000
SBL2 exec address 0x2E000000
as i can upload the sbl to 0x2a000000 but not the sbl2 to 0x2e000000
i can also upload the tz.mbn to 0x2a020000
i am trying to use sec boot 3 based call stack but am unsure of the real exec values
Ive seen in another post these values
"
It looks like ours deviates slightly from this.
If the headers are to be believed,
TZ is loaded at 0x2A000000
SBL3 is loaded at 0x8FF00000
APPSBL/aboot is loaded at 0x88E00000
"
the post is
http://forum.xda-developers.com/showpost.php?p=30057296&postcount=243
it does explain why i cant load into 0x2e000000
Progress
So today i made real progress, I have been able to flash a basic program to allow me to access the EMMC, i have taken a full backup and now i need to start scanning the dump for need information,
I still need help from other users so please if you are will to provide me dumps of your working device that would help me a great deal
So Part One is a sucess, I have been able to flash my own code and power on the galaxy note. next step is rebuilding the emmc partition tables, testdisk can find the partitions but is not alowing me to write a non standard partition table (which emmc seems to be formatted with)
Thanks

Hi,
I'm stuck with the same problem can you tell me what image you use to the phone. I stuck here. I' m really don't know what to do?
Thank you for your help.

First thing i must say is dont flash your phone just yet!! walking blindly into this could render your phone useless due to certain data being lost for good.
if you still wish to continue i will upload a basic guide and files. My method is still in development, it has many bugs ( i flashed the phone with i717 roms, working, SHV-E120 roms, working, N7000 rom complete fail)
But first some questions,
Which model phone is it?
what happened to get you to the point of needing the flash ? ( i ask so i can trace why the bricks are happening and hopefully fix it)
thank you for your help, I will be waiting your method and your files.
Thank you so much for your help.
My phone is a samsung galaxy note SHV-E160L korean version.
what happen was:
I tried to upgrade the firmware with kies and suddenly the program crash. My phone enter in an error issue with the firmware and said use emergency recovery mode.
I tried the recovery several times (uninstalling kies and install it again but that never work).
So, I download odin and this files to restore the original firmware:
CSC - GT-N7000-MULTI-CSC-OZSLPF.tar.md5
Phone - MODEM_N7000XXLR1_REV_05_CL1144476.tar.md5
Bootloader- N7000_APBOOT_N7000ZSLPF_CL558430_REV02_user_low_sh ip.tar.md5
PDA - N7000_CODE_N7000ZSLPF_CL558430_REV02_user_low_ship .tar.md5
Pit for 16GB - Q1_20110914_16GB.pit
I connect my phone and try to install the firmware again, but odin fail and my samsung became a nice brick.
The phone currently does not turn on, the phone is in download mode and I install QPST and the program recognize the system in download mode.
I want to try your method because other information I collected said that I have to send it to guarantee.
Can I install i717 rom in the E160L?
I will be waiting for your post because sincerely I don't know how to repair it.
Thank you so much.
Hello darkspr1te
First of all, nice work there (though I didn't understood most of the things there, but seems there is some good work going on on our SHV-E160's
On your comment;
( i flashed the phone with i717 roms, working, SHV-E120 roms, working, N7000 rom complete fail)
Does that mean that i717 roms can work on the SHV-E160 devices? Please share if that is the case.
The geeky bits

Ok, as i said it's still a work in progress at the moment.
I used the i717 bootloaders (thats why we have a brick as it's not getting to the aboot loader or little kernel as some other refer to it) and E160 modem and application cpu as my first target is getting odin mode back.
I was able to also use the E120 bootloaders (screen was messed up though )
I've just got home from a very long shift so i will do a full and clear write up ( STILL a work in progress ) tomorrow (20th)
but i will explain the basic now as you do need to download large files before we continue.
First you need to download the same firmware as you were originally on before the brick, The reason is because between versions i suspect there is minor changes in partition tables (that why the n7000 roms brick )
If you dont have the latest QPST (2.7.3xx or higher ) please google for it now, there are many sites that offer it. (links will folllow tomorrow)
also down load :-
ABOOT_SGH-I717M_I717MUGLA2_user_CL875155_REV00.tar (or tar.md5 )
i717-GB-Modem.tar (or .md5)
now my initital work was based off a chinese link for the A820L
http://blog.csdn.net/su_ky/article/details/7773273
To save you the time of many hours of translation and cross reference here is the quick run down
When the phone is in QDLoad mode its because the PBL (Stored in ROM , read only memory) could not start SBL1 or SBL2 , it stores the error in IRAM location 0x3FF18 and then goes to QDLoad fail mode. At this point it has tried uart, sd-card before hand and those failed too.
IRAM is the small built in memory of the MSM8660 CPU, it has not initiated the main SYSTEM ram yet so our memory space ro running code is 87k and 256k (refer to document 8960_boot_architecture.pdf found the unlock bootloaders section.
Now because our partition table and or our bootloaders are damaged (or we have emmc brick bug) we have to rewrite that data again to revive our bricks.
This is where it gets hard, and where my warnings now come into play.
right now you must think of the EMMC chip (its the name for the internal SD-CARD we boot from and store our normal data, imei and all the other data of the system, it is just a sc-card with better security for our purpose)
This emmc chip holds all of you settings for phone function and we must not loose that,
But...
we have to write data to the chip to boot again, I am not fully aware of all the memory locations so this is assumptions on my part.
we are going to write a basic bootloader that turns the whole phone into a sd-card, then write new bootloaders
using QPST we upload 8660_msimage.mbn (its a out of the box emmc factory image) this file is ment for setting up of dev versions of the phone, it made up of the following parts
sector 0 partition table or (partition0.bin AFTER patching with info from patch0.xml) I do not have a real copy of the original of this, it can be pulled from a working SVH-E160x using the code at the end.
after the MBR (which is the first part of the partiton make up, EBR follows, we can have 3 primary partitions and the fourth is a extended which is just another partiton table pointing to the next EBR and so on, upto 29 parititons i think)
anyway, after the MBR is SBL1, which chainloads SBL2 then that side loads RPM, gets a go signal then loads SBL3, when SBL3 is done most of the device hardware has been mapped into the cpu's memory table, SDRAM is now ready for larger code,
aboot now loads
some of the above loading functions occur at the same time and some wait on go signals from other code in other CPU's and some fail due corruption and or security check fails( JTAG users can watch the memory as it changes and halt, change data and continue which is why JTAGers's have more power , we dont have loader outputting data yet so no feed back, hence the brick)
when aboot is loaded we now have access to odin, so thats the goal, get aboot loaded for now who cares about the rest of the funtions.
we do need to care about those function later so thats why we will backup the entire system, i dont know if this will really work when restored and bring back all of our settings, thats later,
So onto the writing and possibly overwriting of important information, WARNING, i dont know yet if we are overwriting imei or simalr data yet so proceed at your own risk.
We will get the required from factory (qualcomm test or dev board not samsung factory in the box for consumer) from the MUI phone firmware
http://bigota.d.miui.com/QDN43/Mioneplus_QDN43_fastboot_Android_4.0_d3d83nmdk2.zip
from this zip we want 8660_msimage.mbn, patch0.xml, partition0.bin MPRG8660.hex ( this file is uploaded first, its a serial bootloader that is loaded at 0x2a000000 (start of PBL IRAM space 256k in size) and that setups a emmc to command access (we use revskill to upload the same file and dump memory , sadly ive not found a way of pulling the entire emmc to a backup, if we can figure that out we can pull the entire boot chain, fix it and send it back with what ever versions we desire, for now revskill is used to read the PBL error so we can at least see why we cant boot, not quite jtag but best we got ))
so now we have a phone running a basic bit of code that allows us to use code sent to serial port to write (possibly read) the emmc
we then use QPST to write the 8660_msimage.mbn as a one to one copy to the very start of the emmc , reboot phone and then when the phone restarts, it sets up the ram, some hardware (charging system, you will now notice your phone gets warmer that before when plugged in) and gives us direct access to the emmc as if it was a sd-card
at this point you could move the phone to any pc and it's just a sd-card branded qualcomm
BUT at this point the pc or any other computer you connect it too only see's the partition table contained in the 8660_msimage.mbn file , you other data is there so i advise the next step you MUST do.
connect the phone to a linux computer (use a live cd or live usb if you are not a normal linux user)
you will then run the following command
Code:
dd if=/dev/sd? of=/mount/location/shv-e160-full-emmc.bin bs=512
? is the letter of the drive , use dmesg and look for sdb or sdc , if you dont understand this part then i would suggest waiting for a possible script/one click solution. right now i am still booting only 1 in 20 boots and do not yet know why the boots fail and why some work.
of=/mount... this is where you will place the entire 16GB (32GB for 32gb models ) which should be a one to one copy of the system
the bs=512 is very important, it's block size, again, if you dont understand then maybe wait.
Thats enough for now, i am going to spend a hour or two working on some theories i came up with today.
user with working phones, please google how to backup parts of your phone, this may happen to you so it's best to backup asap !!!
from the blog.csd site a script to grab the partition table data, if a working usr could please run this and post the file, it does not contain user data only the partiton table and a direct 1 to 1 restore for any phone, i think it possible to write that direct back to a QDLoad mode phone, re write the bootloaders from linux and bingo working phone. i dont have backups as it's not my phone, it belongs to a client who knows i like to tinker with electronics.
anyway, once i have the partition file i can overlay it on my test phone (which i can activate QSLoad at any time, hence it's unbrick-able dev mode)
once the partition file is written to my phone, i can build a script to backup your important data, write known working bootloaders, and reboot the phone into a usable device.
here is the script in python (user linux live cd with a copy of adb, just google adb linux pack, there is a windows and linux allin one pack)
or you can get the original from the link above, i've not tested this as i dont have a device in adb mode but i've read through it and it looks sound but never tested by me.
Well i hope that enlightens you, am sorry i dont have a all in one solution for you, it's still a dev project and most of the information i have has only been collected over the past week, i only discovered it's QSDload after getting a msm8660 schematic and i still dont know what i am trully shorting out to trigger the QSDload when ever i want, even when it's booted
If any one from the unbrickable project(s) want to get in touch to share info i would be happy, i am also sure this is a usable solution for HTC phones as well
oh and one last thing
i read only a hour ago (via cell phone while in a car so not 100%) that once the phone is in QSDload and stays in QSDload on every power cycle then we can write the partition table to a SD-CARD and it will boot that, i have not tested that yet, i will try and see if the 8660_msimage.mbn file written to a sd-card works
I also suspect that some of my good boots have been when i've mixed up the sdcard with system.img.ext4 etc on it with the one with just update.zip on it. it's one my list of things to check , any suggestions are welcome as to how i correctly format the card (heads,cylinders, block size etc)
ok folks, hope this helps

thank you for your help,
I currently have the qpst version 2.7 build 373. You think is enough of download the same version of Chinese post QPST.2.7.374.rar
I will begin to download the other files required and I will be commenting my progress.
Thank you so much for your help, i really appreciate that you share you r knowledge.
Requests
While i try some theories if othe users could possibly provide me with :-
Original partition table via script above and also via adb
use
adb and run
Code:
cat /proc/partitions > /sdcard/partitions.txt
fdisk -l /dev/block/mmcblk0 > /sdcard/fdisklist.txt
mount > /sdcard/mountlist.txt
Then on the pc side using ADB again do the following
Code:
adb pull /sdcard/partitions.txt
adb pull /sdcard/fdisklist.txt
adb pull /sdcard/mountlist.txt
and post those files.
there are many posts on it so wont repeat but later will add a link.
along with some spell checks :laugh:
if you can dump the boot loaders from a original e160x too as my data started currupt.
i also need to talk to someone who can assist me in writing a program to take the pit file and turn it into this
Code:
<?xml version="1.0" ?>

*edit
the partiton0.bin provided below is 8.5kb (.5kb MBR, 8kb EBR) and in raw_program0.xml bove it say 0.5kb and 11kb, making that file 11.5kb, i dont know if the A810 has larger or smaller EBR than us, it could be they pulled extra, in my reading of the dumps i've seen lots of padded 0's after files (between sbl2/ebr/rpm) anyway if you just copy paste it will throw a error, ive got it set at 0.5 and 8.
EDIT:- Do not use this file, ive uploaded newer files later on.
some of the questions i need to answer are :-
1. what is the first partition, it's dos, around 105mb and labled smd_hdr and is filled with smd_hdr.bin (or mbn)
2. what are the real sector locations of the files, above you will see the rawpartiton0.xml file, this tells QPST where in the emmc to put the data num_partiton_sectors does match data from the pit files, but i dont know the real offsets yet, (samsung or htc could put the rest of the partiton table in cpu qfuse data areas and not write it to the emmc to confuse us and write the real files to another location and use the pit file as a base+offset calculation)
start_sector is the real location on the emmc, where it starts writing the file.
at the end is partiton locations(its a generic file containing the first few byes of default partition table, patch0.xml then updates this data), i dont have our device specific figures yet, i also dont fully understand patch0.xml and the difference in figures used.
if we have a backup of each of the different version of android partitons we could just write that in replacement of partiton0.bin and we dont need patch0.xml, this file sole job to alter the generic files, oem's have the choice of changing this data.

please note that it's two lines of the same code except one is partition0.bin and the other is DISK,
Do we need both? i know if i dont add the partiton0 section used in raw_program.xml then the drive is blank in linux,
now it's my understanding that the ebr comes as the forth partiton and it point to the next one , above in patch0.xml it start at NUM_DISK_SECTORS-1695744
i am still trying to better understand these figures,
Well time to grab coffee, i guess it's a dev night in.
the file MPRG8660.HEX can be renamed EMMCBLD.HEX and it triggers QPST to always look for a QDLoad mode phone and not debug, you can place all the files you need in one folder, i advise you to keep the originals in one location and only extract what your need to your worrking folder, copy emmcswdowload.exe from the QPST folder there too, we might need to do command line work, ive read that you can pre-create images in emmcswdownload (the same way 8660_msimage.mbn was created ) that you could just drop onto a phone once it's in emmc sd-card mode, almost a one click.
More info, plus help offered
Your welcome tyllerdurdent,
I am going to be putting a few hours into the dev from now actually for if you want assistance then no problems,
I also advise the following, download ubuntu live cd, it has a lot of tools your going to need to extract data you require, if we go step by step we might be good, i did a lot of test writing before i got my first boot, and that again only happens one in 20, i dont know why.
the rawpartiton0.xml above is incorrect for our devices as it states the first partion is 32mb, (i think it's ment to be amss.mbn, or NON-HLOS.mbn , our pit file which i did extract from my emmc dump says it's 105mb. i am confused and to why rawpartiton0.xml says the first bootloader is at start_sector="65537" but fdisk shows it as start 204801, i think someone needs to show me how to convert from blocks to sectors,
in patch0.xml it says
Code:
<patch byte_offset="506" filename="partition0.bin" physical_partition_number="0" size_in_bytes="4" start_sector="0" value="NUM_DISK_SECTORS-208801." what="Update MBR with the length of the EXT Partition."/>

208801 is where we have our ebr start,
i also think the IROM based pbl, sbl etc use the partition types in some way, why else have so many types? can any one explain that
this is a fdisk view of what i think our partition table looks like

Blocks and sectors
This may explain it , the different figure in the xml files
Because sectors are logical on the drive (Logical Block Addressing = LBA) you need to convert between LBA and physical (file system) sectors. This is pretty easy to do:
First - get a table of the start and end sectors of the partition table:
Code:
[[email protected] ~]# fdisk -lu /dev/hda
Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders, total 234441648 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 63 208844 104391 83 Linux
/dev/hda2 208845 4401809 2096482+ 83 Linux
/dev/hda3 4401810 8482319 2040255 82 Linux swap
/dev/hda4 8482320 234436544 112977112+ 5 Extended
/dev/hda5 8482383 29447144 10482381 83 Linux
/dev/hda6 29447208 50411969 10482381 83 Linux
/dev/hda7 50412033 52516484 1052226 83 Linux
/dev/hda8 52516548 234436544 90959998+ 83 Linux
Use this to determine what partition the bad sector is in. In this case 232962120 is inside the start and end values for /dev/hda5
NOTE: This is in partition 5 - ignore partition 4 as it is the extended partition. Any block from partitions 5 through 8 will also be in partition 4, but you want the real partition, not the extended partition.
Next, calculate the file system block using the formula:
b = (int)((L-S)*512/B)
where:
b = File System block number B = File system block size in bytes (almost always is 4096) L = LBA of bad sector S = Starting sector of partition as shown by fdisk -lu and (int) denotes the integer part.
For example:
The reported sector from the smart log above is 232962120, thus:
((14858312 - 8482383) * 512) / 4096 = 796991.125
^Bad Sec. ^Start Sec. ^Cha Ching! This is the sector!
(Use the block number from the smart test section, not from the smart error log section. They are using different methods of reporting file system vs. physical blocks.)
((BadBLock - StartPartition) * 512) / 4096
You can just paste this into Google as a template
Any fraction left indicates the problem sector is in the mid or latter part of the block (which contains a number of sectors). Ignore the fraction and just use the integer.
Next, use debugfs to locate the inode and then file associated with that sector:

[[email protected]]# debugfs
debugfs 1.35 (28-Feb-2004)
debugfs: open /dev/hda5
debugfs: icheck 796991
Block Inode number
796991 <block not found>
debugfs: quit
Ah! It didn't give the inode! It if did, you could have found the file with:
[[email protected]]# debugfs
debugfs 1.35 (28-Feb-2004)
debugfs: open /dev/hda5
debugfs: icheck 796991
Block Inode number

Inode Pathname
41032 /S1/R/H/714197568-714203359/H-R-714202192-16.gwf
So what the heck? Why no inode? Well, remember how it said the sector might be bad?

now i used this in a way to find my bootloaders (i717 by this time, not shve-160l )
and to find the partitons
you will see in a hex editor at the start of each boot loader
something else to think about, my lack of success that last two days to produce a boot could be because my partitons are not clean , thats is to say if i write my sbl1 to 1000, and the trailing 0000 of the partition definition of my 99 block ebr/mbr ends at 999 , if i have dirt data between 999 and 1000 the cpu/pbl my interpret that as code(some of my boots is brick, some are into QDLoad, i have no pattern yet) , something i must test or confirm, or just worry about.

No idea. What you posted doesn't make sense to me. Hopefully someone else will pop in.
I copied from another post but I am getting roughly the same response when I rum the gdisk Dev command in Linux terminal. It does recognize the device as lg. But it doesn't appear to find the device while running the command to see the list of img files.
Also having trouble coding the file extension to push the img files with dd command.

I have always seen posts to add bt_firmware to your file_contexts in sepolicy and file.te, but for me this doesn't work (the directory for me is firmware though...)
here is an example: https://github.com/mukul2259/device_oneplus_oneplus2/commit/2fb4e45a292468bec5205087c99880fab0bd0a65

you need to be precise, do you at least see the lineageOS boot animation or just the logo of your mobile phone brand?
you need to study the logs why it refuses to boot, maybe it's trivial
for me the sepolicy thing didn't solve the error message have no clue how to fix

Hard bricked Moto G8 Power by flashing TWRP to recovery slots

I bricked my phone (XT2041-1 "sofiar") by flashing an unnoficial build of TWRP 3.5.0 downloaded from a Telegram channel by doing:
$ fastboot flash recovery_a twrp-3.5.0-0-rav-sofia.img
$ fastboot flash recovery_b twrp-3.5.0-0-rav-sofia.img
$ fastboot reboot recovery
Since then, my phone is hard bricked - won't boot, recognized on Linux in EDL Mode only (i.e. ID 05c6:9008).
I got the latest official stock firmware, named SOFIAR_RETAIL_11_RPES31.Q4U-47-35-12_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip, from lolinet, and in its contents there's boot.img and recovery.img (among others).
I have qdl on my Arch Linux, and am wondering whether I can use it to flash the stock recovery image back to both slots and get my phone booting again.
How should I approach it?
P.s. I also got a blankflash from https://forum.xda-developers.com/t/...equest-solicitud-blankflash-g8-power.4431193/ that is supposed to get the phone working again, but am unsure whether using it will cause loss of data.
I absolutely cannot lose any data from internal storage.
Any help appreciated. Thanks in advance.
Ok, now we're rolling...
First things first. Motorola sucks because they only give you restricted Firehose loaders.
That means of the 70-odd partitions that you have you can only read/write about 1/3 of them using EDL.
If you post your Firehose loader I can tell you which ones you can read/write.
Second, are you sure that the only damage you did was by writing recovery_a and recovery_b?
And you're on Linux, *sad face*.
I was disassembling the Motorola Firehose for my Moto G (2021) and I discovered that they have more reboot options than stock.
There's reset-to-edl and reset-to-fastboot.
I've added those options to my edl.exe (in the sig) this morning. You need to download the very latest.
What may have happened is that you wrote a bad recovery which may have set the boot option in the BCB or misc.
Since the recovery is good enough to be recognized as an image but not good enough to reset this boot option you're stuck.
Your first recourse is flashing a proper recovery.
I'm not sure whether "blank flash" tries to wipe everything. In any case I wouldn't risk it.
Your first try should be to fix the broken things, not everything.
Yes, any edl client that supports ad-hoc xml should be able to get you to fastboot but I'll only answer for my code.
I've tested it.
Code:
C:\>edl /lwhatever.bin
C:\>edl /zf
C:\>fastboot flash recovery_a good_recovery.img
C:\>fastboot flash recovery_b good_recovery.img
C:\>fastboot reboot
I admit to not properly understand what a firehose loader is. :x
Second, are you sure that the only damage you did was by writing recovery_a and recovery_b?

Yes, 100%.
So, for now, I should try booting Windows, installing the 9008 driver and following your instructions... Will let you know how it goes.
Thanks a lot.

A Firehose loader is a replacement xbl/sbl secondary loader that has special sauce added to it to make it interactive.
It is not to be confused with a Windows driver (which, in this case is Zadig, as per the instructions on my web page).
In this case, your Firehose loader is packed in singleimage.bin in the RPE here: https://mirrors.lolinet.com/firmware/motorola/sofiar/blankflash/
I extracted it for you. I renamed it sofiar.bin
The extension name does not matter.
Code:
C:\>edl /lsofiar.bin
That's slash-ell-sofiar.bin
Edit: And yes, your Firehose loader has the reset-to-fastboot.
Right, thanks for the explanation. I figured that was programmer.elf from my files.
Ok, I got as far as:

But it doesn't boot to fastboot.
It seems to me that your tool, edl could be used to write the recovery partition directly, no?

Nope
P.s. curiously, the file I downloaded from https://raw.githubusercontent.com/b...a/0010a0e102e80000_974359c4290cac7f_fhprg.bin wasn't accepted as a valid firehose loader file.
Edit: nevermind. Had to restart the phone.
I believe that's an older loader, anyway.
How shall I proceed?

Hmm, the screen stays black?
Is it still in EDL mode or some other mode?
Does Windows "bong" when you pull the USB cable?
It's possible that this goes to a fastboot without a screen?
Try holding various buttons, both by long power button reset and /zf

Yes, it could if Motorola wasn't such a pain with the "range restricted".
They've really clamped down (that other file you mentioned is the same):
Code:
qcomview /r sofiar.bin
Addr LUN Start Count
------ --- -------- --------
007f10 0 0 256
007f28 0 256 78336
007f40 0 1609948 512
007f58 0 1610496 512
007f70 1 1 1
You can do this to see which partitions this means:
Code:
C:\>edl /lsofiar.bin
C:\>edl /g
I have a feeling that the Motorola "Blankflash" stuff writes something to those 3 areas that allow it to write everything.
But it probably wipes the userdata.
I'm not an expert on their tools.
Tell me what the GPT says (you only need to quote stuff in the area of that table).
Edit: It looks like in the multi GB zip there are two "instruction" files, flashfile.xml and servicefile.xml
They are mostly the same except that flashfile will wipe userdata!
Curious. The partition table is as follows:
Code:
Found EDL 9008

Requesting GPT 0 header... Ok, receiving... Ok, requesting entries... Ok, receiving... Ok

While programmer.elf (same as sofiar.bin that you uploaded) lists, additionally, QCM_NICOBAR and QCS_NICOBAR.
I wonder whether this is actually the correct file for me...
Btw, before attempting any further writing strategies, I confess to being interested in pulling userdata. As I understand the real decryption key is stored in the TEE functionality of the chipset and such an image would be unreadable for me, except if I were to restore it later.
With your tool I got the "range restricted" for edl /r /puserdata parts\userdata.img /t too.
Code:
Addr LUN Start Count
------ --- -------- --------
007f10 0 0 256 - GPT
007f28 0 256 78336 - xbl_a to prov_b

So, basically, you have free read/write access to partions 1 to 34
Reading is always safe.
Also, you're on the B slot.
So why does reboot to fastboot fail?
It could be that it was never implemented correctly in this Firehose
It could be that this Firehose is not for your device
It could be that xbl and/or abl was damaged somehow
I'd do some checking, xbl_b and abl_b to start with.
Read 'em then compare them to the xbl and abl you have in your big packages.
Code:
C:\>edl /lsofiar.bin
C:\>edl /r /t /pxbl_b xblb.img
C:\>edl /r /t /pabl_b ablb.img
The /t will copy these ELF files only as big as they need to be (not all the blank space).
OTOH, they will enlarge to an exact number of 512 byte sector.
So they could be 511 bytes bigger than what comes out of that package.
If things are wacky, try without /t, but they'll be padded with all the zeroes in the partition.
If those files aren't in the big package, here's ones I extracted from the blankflash.
Check 'em all.
Also, it's possible that somehow the slots got switched.
While you're at it, look at xbl_a and abl_a also.
Hey, thanks for the continued efforts to help me. Sorry for absence for the past days, real life caugh in ^^
I'm glad to report that, amidst some binary checking and all that, I managed to resuscitate my phone using the blankflash strategy, after carefully revising it.
Strangely, it seems that TWRP got installed in the boot partition, such as that "normal boot" kept entering TWRP, despite I having flashed the stock recovery images to both recovery slots. I'll detail this all later.
At this point my phone is on and I backed up what I needed, and have been using it. A few strange glitches are present, i.e. battery charging is acting weird. I plan on doing a clean flashing of the stock ROM soon. Maybe I should take the opportunity to study how to make a fully working port of the latest LineageOS for this device, too.
Will get back within a few days with a detailed report of the endeavour

I'm looking forward to hearing how you got EDL mode working.
I bricked XT2041-3 Sofiar (downgrade to A10) and am stuck trying the phone to succeed at qboot blank-flash, but it hangs (on linux):

With --debug=2 there can be seen some parsing errors in xmls being passed for about 13 more seconds. On Windows VM phone is recognized as a single QDLoader 9008 device, but qboot fails after half a minute with IO Errors. Is this even EDL mode?
A tried without luck Renate's edl tool. edl.exe /lsingleimage.bin:
Code:
Found EDL 9008
Could not open device
I was growing increasingly desperate, so I opened the phone and played with EDL points according to
MatiasLopezxD. No combination of vol-, power, shorting points, plugging usb seem to make a difference. I must be missing something simple.
Any help would be appreciated.
@ybea: Quick answer for now - I got into EDL mode by holding down VolDown+Power for about 8-10 seconds. Let me know if it works for you. What's your output for lsusb?
Same as yours - ID 05c6:9008 (Qualcomm, Inc. Gobi Wireless Modem (QDL mode)). It reconnects after pressing power for 9 seconds (with or without vol-), nothing new.
Try restarting it into EDL mode while it's plugged. I found that to be necessary sometimes.
Edit: Btw, I don't remember why exactly, but I only had success running the blankflash from Windows. Linux didn't do the magic, nor a Windows VM with USB redirection...

That was it! I didn't event try it on the metal, because Motorola driver installer and uninstaller crash for me for some reason. Should be straightforward from now.
Thank you so much. You saved the day.

Sorry. edl.exe uses the generic Zadig (i.e. WinUsb) driver).
If you have the Qualcomm driver loaded it's stealing the poor WinUsb interface and forcing it into some bogus virtual com port.
Also, singleimage is Motorola's completely morally bankrupt idea of packing stuff in a file.
It is not a Firehose loader, although it contains one.
Add to all your miseries, Motorola is crap and releases only restricted Firehose loaders.
If you're still stuck, ship me the "single-and-totally-bogus.bin" and I'll extract the Firehose loader for you.
Better poke me or I won't see it.
No longer stuck. The problem for me was neither VM USB passthrough nor blankflash tools for linux did work, although both showed proper EDL mode. It seems it only works on native Windows. Thanks for your interest.
