I flashed it on my GiONEE Dream D1 and it worked, but didn't work as desired. Part of the reason is that on MMX A116, I believe the /system partition is p5 where as on Dream_D1, it is p6,
Will it ibe possible for you to make this available for Dream_D1?
Or otherwise, if you could provide the steps, that'll also help.

give me the mount points of Dream_D1..
So basically you have moved space from phone partition to internal partition.
Can you try also this thing :
System is 634mbps and most roms use around 530 mb. Leaves around 115mb free. If we could use this memory into the internal storage partition...... ?

I would not like my /system to be touch. For the simple fact that I'd like to keep playing with it. By having extra space, there's a lot of flexibility to try things out.

NO. Actually, it has a role to play. I think you need to select your choice from the APK and then use the EBR files for YOUR device. And then it works.

True what you say. I only asked since I saw what you accomplished and when I had a nexus one a dev managed to modify system, data and cache partitions. I do not think that type of thing may work here as the board partition architecture is completely different. Anyways it was just a question.

Hi guys, I tried ext2fs and ext2fsd to see my ext2 partition on windows but I just can't see it. I tried rebooting my phone and computer but I only see the fat32 partition.
Anybody ran into it before ?
Btw, I would like to make my own rom so does anybody have any tutorial for me ?
Tutorial like : how to include your apks and saves that titanium backup does.
Btw I would like to explore my ext partition cuz some apps give me error when updating so I want to check the remaining room.
I am also seeking for the best superuser apk at the moment. Cuz for example,what the hell do I do if I prevent an app from using root access and its an error ? I mean ok I can click on the entry on Superuser but after that Superuser didnt ask me about root access and I had to reflash the rom cuz it was unusable.
(I already tried to flash a zip containing a superuser but it gave me an error at line 7 lol ... and trying to launch the apk with astro didnt work)
Thank's guyz
btw : all my recent nandroids backup fail when restoring telling me to use adb but adb just tells me files are corupted. < dead micro sd ? :// what's your opinion is it a frequent error or anything?

You can see your ext partitions via adb shell, i forget what the mounting command is but i believe that's the only way to see it.
for ext partition:
put your card in external card reader, then you'll be able to see all partitions.
if you're using phone to read card, it will mount only fat partition, bcoz ext is in constant usage, so you have no access to ext via windows (you can get access via adb shell)
remaining space on ext you can see for example in android explorer.
questions about cooking rom
topics with tutorials how to create own rom are somewhere on this forum, use search.
and create separate topics for each problem, post title is only about ext so probably nobody will answer rest of questions. i see that are questions absolutely independent of ext part about which is this topic.

That's not true and won't work - Windows cannot natively mount linux partitions. There are some tools to allow you to access them read only but not advisable.
If you want to access the ext partition, you will need to use linux so either set up a dual boot system or use a live CD.
What I think zbaracki was getting at was that you would need to remove the card from the phone to see the partition with anything other than ADB, but even then, Windows won't see it.
HTH.
Smiffy.
You could create a Linux virtual machine using VirtualBox. That would put Windows to good use!
There are ext2 plugins for Total Commander.
Free.
Easiest solution for Windows: http://www.fs-driver.org/
Others solutions: boot a Gparted LiveCD or Install Ubuntu (dual boot if not ready to be a full linux user (don't forget your phone is running on a linux kernel ))
I have done via ADB!

My method:
To check whether App2SD is set up really, there are two possibilities. The first would be that you control whether the links are set correctly on the SD card. For this you start adb shell with the argument:
adb shell
And give it one in the shell:
ls-al / data
Then, the folder app, app-private (and depending on the after-A2SD also the folder version Dalvik-cache) to the SD card reference, there should therefore be read as:
app -> / system / sd / app
app-private -> / System / sd / app-private
Under certain circumstances also:
Dalvik-cache -> / system / sd / Dalvik-cache
Then Apps are stored on the SD card.
Otherwise, you can still see if enter the Ext-partition (for the apps) is properly mounted, this again in the adb shell:
Mount
Then all mounted partitions are displayed, the App2SD partition should be this:
/ Dev/block/mmcblk0p2 on / system / sd type ext2
To check how full the partition is, you give a:
df-h
Then you will see an overview, how full the partitions. The partition for App2SD you find i.d.R. here:
/dev/block/mmcblk0p2 228.8M 719.0K 215.9M 0% /system/sd
Hello,
I picked up a Meizu MX2 while I was in Hong Kong last week. I've succesfully rooted the device, but now I'm trying to compile CWM for it and need to save a boot.img file.
Unfortunately, I can't seem to find the boot partition at all. Any ideas would be appreciated.

finding boot image partition
[
QUOTE=bakedjake;36394241]Hello,
I picked up a Meizu MX2 while I was in Hong Kong last week. I've succesfully rooted the device, but now I'm trying to compile CWM for it and need to save a boot.img file.
Unfortunately, I can't seem to find the boot partition at all. Any ideas would be appreciated.

Based on the information you have provided, you have four visible partitions on the flash. With three used by system, data, and cache, I would expect the remaining partition to be boot ( mmcblk0p1 ). I would do a dump of all partitions as back-ups for a future restore if necessary.
dump the partitions with "cat /dev/block/mmcblk0p1 > /sdcard/mmcblk0p1.img"
substitute the names of the partitions accordingly. I recommend you install an external sdcard larger than the built in and save the images there.
If you do look at the image files with a hex editor, the boot image partition will have the boot command string usually in the beginning of the file.
Good luck

download the boot partition app from google play and click on the middle lower button after open then you can click on the partitions to tell you the label number and what it is ass boot or recovery or sbl1

I agree. This is the correct method. No need for crappy apps from the playstore for such a simple proceedure. And you remain in control.
yes but some rather play it safe and not mess with commands but the app is partition table

This seems a pretty difficult way to go about this.
The easiest way is to use adb:
Code:
adb pull /tmp/recovery.log
If using Windows and you want to pull out to your desktop
Code:
adb pull /tmp/recovery.log C:\Users\Your Name\Desktop
Open the recovery text file using notepad++ (you can use notepad but it's not at all organized) and the first dozen lines or so tell you specifically which each partition is (boot, data, system, cache, etc) relative to it's mmcblk0p_ . This was the only way I could find my boot partition after trying every cat /proc, fdisk, parted, command I could think of. Hope it helps!
Try looking at /proc/mtd , on some devices it usually contains names and descriptions of each MTD device present on the system.
Hope this is the right place to post, I've been lurking around the forums since I got my first smart phone a few years ago but never posted as I've usually found what I'm looking for through googling and rtfm'ing, only reason I came out of the shadows was to get my Kobo Arc 7 rooted. No way I could live without it, I had been watching this thread http://forum.xda-developers.com/showthread.php?t=2507886, checking it every few days to see if there was any development when I saw development was pretty much abandoned on the Arc 7. So this all started with a pm that made me try getting root myself with a little help from dazza9075.
Basically was told to trade in the arc 7 for an arc 7hd, barring that I could try the new cydiaimpactor update and see if it worked. It went something like this. I followed the instructions for the 7hd:
Root
Fully setup device
Download impactor on PC from http://www.cydiaimpactor.com/
Download android SDK on PC, from http://developer.android.com/sdk/index.html
Run SDK manager and acquire the google USB drivers
Enable dev mode on device by going to settings, about kobo, and tap build number 7 times
Enable USB debug mode in developer options
Enable unknown sources in security options
Plug in device and let it install a USB composite device and a arc 7hd drive, it will fail on the third, go to device manager, and manually install drivers for the "arc" device that's highlighted with an error.
Click on it and update the driver, browse, let me pick my own, show all devices, click next, have disc. click browse and navigate to your android SDK>extras>google usb driver, for the correct drivers, select ADB interface
Run the impactor program downloaded earlier, once loaded, click on start
Check your device screen, you should see an error message, click on decline then decline again and finally decline again, (not sure that makes any difference)
Go to the market place and download SU by Chainfire

Everything went fine until plugging in the device to let it install a USB composite device. As expected it did fail on the third but when trying to install Google USB drivers it couldn't find any for the device. Just for kicks I opened up Impactor and pressed "Start" it did nothing, I then clicked "USB Scan" and let it complete, then pushed "Start" again. Quick popup on the screen, so I swiped the screen and ran Root Checker Basic and voila I had root.
Since then I've pretty much been badgering dazza9075 through pm to see about getting a recovery for it, I'm an old school linux guy, but never spent much time doing any development, so trying to figure things out myself is usually not an issue but this is new to me. I've been utilizing my google fu to try getting a recovery image made and had some success. Basically started with the instructions for dumping the partition info via dazza's instructions. Turned out to be a little more frustrating than anything, all the commands were turning up nothing, then finally I checked chipset specific stuff, it's running an MTK8125 so after getting nowhere with:

So I focused on googling emmc partition tables and stumbled upon this thread http://forum.xda-developers.com/showthread.php?t=2450045 which again I followed with little success. I had already tried way 1 and way 2 and way 3 couldn't read the partition table. So I followed the comments and #3 mentioned "cat /proc/emmc", so:
Code:
[email protected]:/ # cat /proc/emmc
cat /proc/emmc

emmc_p1: 00000400 00000002 "ebr1"

Still not giving me a good picture of the partition table so I followed that thread till the end which took me to this thread, http://forum.xda-developers.com/showthread.php?t=1959445. So in fashion I started following that. So

So I read on to the emmc section of that thread and understand nothing, more google fu gets me here: https://github.com/ameer1234567890/OnlineNandroid/wiki/How-To-Gather-Information-About-Partition-Layouts. So now I'm looking at the emmc stuff thinking this really doesn't help me, but remembering I'm running an mtk chip I was pretty happy when I got:

Bingo, so finally, root, partition info, next recovery. Again I'm green here so I searched and searched and searched until finally I found the lenovo has the same chip that someone else had managed to get a recovery installed. So I've spent most of my day with this page, trying to get a recovery installed http://forum.xda-developers.com/newthread.php?do=postthread&f=613. So I managed to get everything done, booted into CWM recovery, finished up all excited, then started testing CWM first reboot and I'm back to the stock android recovery. So I ended up finding the recovery.img that was created through the steps in the above link and did:
Code:
adb shell
mount -o remount,rw /system
mv /system/recovery-from-boot.p /system/recovery-from-boot.p-orig
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh-orig
As this was apparently a known problem with some samsung devices. Then:
Code:
fastboot flash recovery "path to recovery"
Which I cut and pasted the path, then rebooted the Arc 7 into fastboot by holding down the Volume up and power slider for aproximately 30 seconds. Fastboot was successful but hung after installing the recovery.img so I hard rebooted and got back into the arc. So I've tested it a few times and now it's booting into CWM recovery, I had two backups made during the image creation process and have been able to restore from both backups, tried creating a backup which completed with an error, can't remember what it is at this point though I will try again later. Only thing I'm noticing is when I boot into recovery it throws the following errors.
Code:
CWM automade 03.02.2014 11:23:02
E:Can't mount /cache/recovery/command
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last-log
E:Can't open /cache/recovery/last_log
At this point I'm not sure if this is a problem or not as so far everything seems to be working, I will continue testing this recovery out then hopefully post it to dazza9075's original thread. At this point I really don't know what to do from here and any input would be greatly appreciated, dazza has been a great help but I'm at the mercy of being in different countries and timezones, so the pm process is always a little hurry up and wait. Apologies again if this is the wrong place to post, and thanks to all the people in the other posts above for all the hard work they have put in. Hopefully having some of this information in one place will help others with Microtek Chips.
Good work mate!
Have you tried creating a backup yet? and can you post the contents of your FSTAB?
The important one for you is probably to get the SD card mounted, with the internal storage quite low backups will be tricky, so we need to be able to mount an external SD card and use that for the backup.
I wouldn't be to worried about the other partitions that haven't mounted yet, lets concentrate on the important ones, /system /cache /recovery /boot
once we can confirm that you can back then restore we can tidy up the other issues.
Good work mate!
Here is my fstab:
Code:
# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

/[email protected] /cache ext4 noatime,nosuid,nodev,noauto_da_alloc wait
/[email protected] /data ext4 noatime,nosuid,nodev,noauto_da_alloc wait,encryptable=footer
It appears that my external sdcard is getting mounted for backups anyways as my backups are all being found in /storage/sdcard1/clockworkmod/backup/. Here is the output from CWM during the backup:
Code:
E:Can't mount /cache/recovery/log

Checking the new backup folder created only yields boot.img, data.ext4.tar, recovery.img and system.ext4.tar
Pretty much looks like we just need to get the /cache mounting properly then it should go off without a hitch.
Correction, just tried wiping the cache from CWM rebooted to delete the failed backups off the device, booted back into recovery and was greeted by the stock android recovery.
Okay so after getting the stock android recovery after wiping the cache 3 times I decided to start fresh.

rebooted kobo, everything seems to be in place. Boot back into recovery to make sure it's cwm not stock android.
Rom Toolbox Lite -> Rebooter -> Reboot Recovery. Bam, back into CWM.
So it is backing up to the external sdcard and can restore from there it just can't do it automagically!?
Regardless aside from not finding ext-sd everything seemed to work.
Have you disabled the auto recovery repair thing? I'm away from my computer at mo but if you kook at the arc recovery rom process there is a file you need too delete, that stops custom recovery getting replaced at boot

I renamed those files as I had read they were causing similar issues on Samsung devices. Now they are renamed and moved to another folder. I'm flashing http://forum.xda-developers.com/showthread.php?t=1916098 right now. it backed up okay, but couldn't find the file. The zip was saved to /sdcard/downloads but its reading my sdcard which is /storage/sdcard1 as /sdcard.
I did a wipe to flash that and when it couldn't find it it rebooted to factory. I'm back in CWM doing a system restore from the backup it just made. So it is working, just seems to be issues with paths. I am able to flash manually once in CWM though.

your Fstab is very odd looking, it does look exactly like what you find within android but the recovery ones I have been using are a little different
here is mind
Code:
/system ext4 /dev/block/mmcblk0p3
/sdcard datamedia /dev/block/mmcblk0p8 /dev/block/platform/mmcblk0
/cache ext4 /dev/block/mmcblk0p4
/data ext4 /dev/block/mmcblk0p8
/recovery emmc /dev/block/mmcblk0p1
/boot emmc /dev/block/mmcblk0p2
/misc emmc /dev/block/mmcblk0p5
/staging emmc /dev/block/mmcblk0p6
/metadata emmc /dev/block/mmcblk0p7
That is for the 10HD, /SDcard in this case is an internal chip, there is no external chip, I have to have it set at "data media" but on the original Arc I have it set to "vfat". For the 10HD I cant manually mount /SDCARD, but it does do it itself when backing up and restoring but on the Arc it works fine, I can manually mount and unmount. Im a little unsure why its not working on the 10HD, a chap was going to have a look for me but hasn't yet got back to me.
format is
/mount_point Mount_type /location
below is the fstab of Astrali, his been a good help with mine
Code:
# mount point fstype device [device2]
/boot emmc /dev/block/mmcblk0p16
/cache ext4 /dev/block/mmcblk0p18
/data ext4 /dev/block/mmcblk0p21 length=-16384
/recovery emmc /dev/block/mmcblk0p13
/misc emmc /dev/block/mmcblk0p11
[B]/sdcard vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1[/B]
/system ext4 /dev/block/mmcblk0p17
/sys_boot vfat /dev/block/mmcblk0p3
/FOTA emmc /dev/block/mmcblk0p19
[B]/sdcard1 vfat /dev/block/mmcblk0p20[/B]
[B]/sd-ext auto /dev/block/mmcblk1p2[/B]
#added sd-ext support by Astrali
[B]/external_sd vfat /dev/block/mmcblk1p1 /dev/block/mmcblk1[/B]
#added for rom manager support
Here we can see /external_SD and /sdcard are actually the same thing (?) mounted from blk1p1 (likely an external Sdcard) I don't know why there is two mounts, perhaps different software looking for the same thing but in different places?
/SDcard1 is mounted from blk0p20 so probably internal storage,
/sd-ext however is mounted from blk1p2, likely a second partition on an external card
/boot mtd boot
/cache yaffs2 cache
/data yaffs2 userdata
/misc mtd misc
/recovery mtd recovery
/sdcard vfat /dev/block/mmcblk0p1 /dev/block/mmcblk0
/system yaffs2 system
/sd-ext ext4 /dev/block/mmcblk0p2
keep this in mind, im just building a recovery img just now based on this...
Can you please upload kobo arc 7 stock rom or system.img
Firstly, mods, please! Move me to a different forum if this thread is in the wrong place, I'm not used to posting on xda (usely searching is sufficient.)
Updates: Method to restore your ME170C* from a brick! See below for the guide.
I just picked up a ME170CX at a local Meijers in the Thanksgiving sale. It has pretty decent hardware and the default UI is pretty nice, overall. However, the previous tablet I used (and still do) was the Acer Iconia A500, which has the good luck of a custom bootloader, a 4.4.4 OmniRom port as well as a bunch of other stuff, and an extremely recent CWM. Long story short, I'm spoiled on .bat scripts and a convenient APX flashing utility by NVidia.
Since I'm essentially blazing the trail, I'd really like a few ideas to get started. Again, my plan is to compile CWM, make a flashable root package, and to (eventually) put together a custom ROM. So far, this is the info I've collected to that end:

Although I should have guessed this, the Intel support page did not indicate the arch and I ended up checking on Wikipedia. As soon as a saw that the processor was a x86, my hopes of a generic BOOT.IMG were dashed. Sure enough, after pulling off images of all the partitions of the device I found that the two flagged boot are neither a .tar file of any recognizable type, nor a partition type I'm familar with. After mounting the system directory I can't find anything useful. As far as I can tell the device doesn't have a standard issue bootloader/recovery setup but somehow has the two interlocked. Either that or the recovery is in the panic partition and I just can't identify it as such. The recovery-from-boot.p file still exists, so that's a little comfort.
As a side note, fastboot has a custom file format for use with the .img flash system and has kindly neglected to post any documentation that I can find on the format. Without that the raw imgs I have of partitions are essentially worthless.
Does this mean the project is going to fail? No, I just have to begin warming myself up to arguing with ASUS over releasing source, something I don't relish. If anyone has some familarity to dealing with manufacturers' over source, I'd love to talk to you!
Basically, after my updates, what I need to begin is a few good ideas of where to go next with these:
Root - Completed
Method to deduce the partitions' actual uses or names - Aborted for the present, focusing on getting ASUS source
A link or explanation of how exactly FASTBOOT installs images so that the system image file can flashed properly.
Device tree for the ME170C or ME170CX.
Expert guidance.

Thankee very much, sorry for my ignorance on some things. Hey, everyone has to learn!
Update: Root found and partition progress has been made!
Thanks so much! Worked perfectly!! Glad i have root. Ill be following this thread. A custom rom would be nice:good:
Thanks
Thanks for all your work.
I'm posting to let you know I'm following the progress. My skills are too basics to be useful but know that your work is appreciated.
A beer on me.
Cheers
Thanks for the support, everyone! I'll keep pushing.
Updates: Architecture turns out to be x86, no conventional BOOT.IMG seems to be surfacing. Trying to get ahold of the ASUS support for the source tree.

I wish i was more help all i can really do is offer support and test easy things lol
P.s. I also picked this up on thanksgiving day sale. At hhgregg
Thanks for starting the thread...
Already bricked one, but I have another. Tell me, would resetting after five seconds had elapsed (as opposed to exactly five seconds) after applying the root exploit corrupt this process?
Still willing to root the second one... for science.
Thanks!

I'm about positive that the app tells you to wait 10 seconds not 5. For the bricked one I added a guide which should hopefully revive it.

That could be true! If that is the case I am probably closer, as I waited a few extra seconds. I got distracted for a few seconds and proceeded to reboot. Just let me know when/if I should try on the other device, I can't wait to root this thing.
My eventual goal is to run multiple various Linux live images from th SD card.
Thanks for the response.
Update: More bad news. My tablet's battery for no reason at all failed and won't recharge. There will be some delay on further progress while I RMA it. Sorry, guys! :crying:

Firstly, mods, please! Move me to a different forum if this thread is in the wrong place, I'm not used to posting on xda (usely searching is sufficient.)
Updates: Root found and partitions have been ironed out more thoroughly, although I still need help figuring out what partition is the recovery.
Root method is in the apk below, follow it's instructions very carefully, I will not be responsible if you brick your device! Thanks, RootZenfone!
Updates: Lots of new discoveries, some of which are great and others are rather depressing, check the bottom of the page for new downloads!
I just picked up a ME170CX at a local Meijers in the Thanksgiving sale. It has pretty decent hardware and the default UI is pretty nice, overall. However, the previous tablet I used (and still do) was the Acer Iconia A500, which has the good luck of a custom bootloader, a 4.4.4 OmniRom port as well as a bunch of other stuff, and an extremely recent CWM. Long story short, I'm spoiled on .bat scripts and a convenient APX flashing utility by NVidia.
Since I'm essentially blazing the trail, I'd really like a few ideas to get started. Again, my plan is to compile CWM, make a flashable root package, and to (eventually) put together a custom ROM. So far, this is the info I've collected to that end:

Instructions
Recover from a failed root attempt -
First, you're going to need to install the Intel drivers at the bottom of the page.
Next, follow the instructions to setup fastboot in this guide. (Make sure you setup your PATH right)
Next, you're going to need a copy of the system partition, which you can find at the bottom of the page.
Once you have the system.img downloaded, turn on your tablet while holding both volume buttons down and the power key. Release the power key after three seconds and wait for it to boot.
Once you're in recovery mode plug the tablet into your computer with the handy MicroUSB cable.
Open up a command prompt and navigate to the directory you downloaded the file to. (Google for some guides on the command line)
Run the command fastboot devices. Three things could happen: 1. "fastboot is not a recognized command", you didn't install fastboot properly. 2. Nothing happens in which case the Intel drivers aren't working or your device isn't connected properly. 3. A bunch of random numbers, a space, and then a smaller name.
If the previous command worked out to #3, run fastboot flash system system.img. If it appears to be doing something, let it sit and don't disturb it. If it just says something about system.img not existing, you didn't go to the right directory.
If the command prompt comes back and tells you it worked then unplug your tablet. (If it didn't work, send me a PM with info.)
Next, use the volume keys to highlight "Wipe Your Device" and use the power key to select it. Select Yes and wait. Then shut off your tablet and reboot.
Hopefully, everything worked and you have a working tablet!:fingers-crossed:

only difference i can see is the amount of memory they have. Every thing else is the same looking at the specs.
it seems that we *might* have been given a way to unlock the bootloader?
So I was looking into the Asus firmware/rom update

That's good news! That would be awesome to see lollipop and custom kernels on this thing. Just gotta get together with some smarter people than I
well this is my new project, downloading the kernel source and newest firmware now.... still no cwm or twrp / no way to flash it if we did right?

As far as I know you are correct. No way to flash. Only root as far as I know. Far from a dev but glad to hear its being worked on, thank you!
Sent from my Nexus 6
Just to clarify, this is the way things are panning out:
1. It's unknown exactly how the ME170CX boots into flashboot. It could either be bundled with the boot.img or somehow a part of the panic partition.
2. I was unaware that .img files required a specific format in fastboot (I just assumed that when a "*nix" system makes an .img file it's an .img file not a .customformattedpartitionwithanunneccessarydescriptorimg) It'll be a while as I try to figure out how to take the raw image of the system partition and turn it into something that fastboot will accept.
3. Projects in RL are making it rather difficult to keep up with things so updates won't come quickly.
4. If someone is able to make a breakthrough with the boot system or with the fastboot img, I will be glad to add their post to the OP.
Thanks, hang in there guys! We'll get there eventually. :crying:
A hopeful bump. :thumbup:

I was able to install lollipop on my phone. But I couldn't get root. I lost some information. So I went back to my backup 4.3 within TWRP and that's when it all went to ****. HWuserdata can't be mounted and sometimes internal_sd can't be mounted either.
What I can do:
-Install new roms
-Install backups [restore them]
-Access to adb
-Can push out img through through adb/fastboot
What I can't do:
-with all of the above, the internal sd doesn't mount in ANY of the roms [both 4.3 and 5.1]
-Can't remove /hwuserdata in TWRP
-Can't remove /internal_sd in TWRP [Error message: E: Unable to mount '/internal_sd']
More Error Messages:
E: Block device not present, cannot wipe internal storage.
E: Unknown MTP message type: 1
E: Unable to wipe 'internal_sd'
Updating partition details...
E: Update to mount 'internal_sd'
Available Partitions as in the Wape menu within TWRP 2.8.7.1
-Dalvik Cache
-Cache
-data
-Internal Storage 11975MB
-System
-Custom Storage
-Internal Storage 0MB [There is actually two of these partition.]
-External Storage
-USB OTG
My best guess is delete the internal sd some how. And/or remove /hwuserdata as well. Or completely return it to stock. Then install 4.3, install TWRP 2.8.7.1, install 5.1, and finally install root. I can't find the img file to push out through adb in "Fastboot&Rescue Mode".
Can someone point me to stock img? This didn't fix my issue within TWRP. I tried installing "MT2L03_B148_Stock_ROM.zip" within TWRP.
All advice would greatly be appreciated.
Thanks!
UPDATE 7/2:
sdcard0 / internal_sd is still broken after applying the downgrade and the b309 rom. Does anyone have the stock rom in an img file format?
Download the public preview of B309 from the blog.
Install it as instructed in the blog post. (You will lose your data, so backup.)
To root and get TWRP, do the below.
Credit to Foltz61.
1. Boot to bootloader.
2. Fastboot boot TWRP-L.img
3. Install supersu-2.49.zip (even though I didn't lose root)
4. Reboot back to system.
5. Reboot back to bootloader.
6. fastboot flash recovery TWRP-L.img.
7. fastboot reboot.
8. Boot to recovery and had TWRP
Thanks for the reply. But I am still stuck with a broken sdcard0 / internal_sd partition. Does anyone have a stock rom in an img file format? Applying the B309.zip and downgrading to 4.3 provided by Huawei still hasn't fixed my problem.
Oh my God...... Which version of TWRP did you use when you restored using your 4.3 backup???
Please, tell me you did not use TWRP 2.8.7.1-L or 2.8.7.0-L for that matter???
in current state, maybe you can try use parted to print your current partition table, and paste here
adb within twrp, it has parted builtin, under OS, you need install the binary.
parted /dev/blk/mmcblk0

I installed 4.3 with the huawei files and went over to 5.1. I am not sure if I am in the clear yet. I have a "emulated 0" partition for my sdcard0/internal_sd. When I open ES file browser, it says "no sdcard can be found". But I can write to this "emulated 0" partition. I am guessing this is still broken? I am on TWRP 2.8.7.0 with 5.1.

Open terminal, type and enter, su, then type and enter, mount. Share with me what mount says.
That's the same as mine

The emulated 0 partition is the same as I have. That should be your internal memory.

Still, to be sure he didn't screw something up since he did use TWRP-L while on 4.3 JellyBean, I still want to see what, mount, displays for him on his terminal.
Emulated partition
I'm using X-plore file manager and I'm not seeing internal_sd but rather getting the internal SD drive showing up under Root/Storage/Emulated/0
I've tried reverting back to 4.3 and associated TWRP, but X-plore still doesn't show internal_sd properly. I'm pretty sure it used to show it properly...or am I imagining it

On 4.3 yes, on 5.1 yes, but on 5.1 it's main location is /data/media/0
You can check by opening terminal and typing then entering, mount.
so as long as it accessible by going to /data/media/0 then its all okay, even though it doesn't show up as an actual drive under X-Plore?
Thanks for your time and help.

Mine is also screwed up after the upgrade and I cannot get back to stock, nor can I get TWRP back. Yes, I've reflashed supersu etc. Here's my dump.

Updated to 5.1 (was a beta tester). After the upgrade, root, but no TWRP. Tried numerous times to reflash TWRP-L but still the stock EMUI 3 persists. Have verified I can fastboot TWRP to restore previous backups and create new backups but cannot make TWRP permanent.
Have tried the reinstall of SuperSI 2.4x and all the steps multiple times with no success. Tried the Huawei downgrade to B148 and that fails as well.
Regarding trying to install TWRP, that is because of the 5.1 Rom. It checks to see if the recovery is stock. If it isn't then it will overwrite the custom recovery. TWRP has to be booted and system has to be mounted as read/write, not read only, in order for it to patch the Rom so TWRP will stick.
I can't help regarding the beta test Rom though. I was not a tester. So I cannot say specifically what changes there were between the beta Rom and official released Rom. Maybe @xordos, @kimtyson, @Iguanadon, @ScoobSTi or someone else can assist regarding your current dilemma.

Try removing anything related to twrp on internal and/or external sd. Backup if needed. Then fastboot boot twrp. You should get the prompt about read/write.
Edit: remember to use 2.8.0 L

I am also new to the 5.1 fused internal storage. following is what I noticed.
/sdcard is soft link to /storage/emulated/legacy, which in turn is link to /storage/emulated/0, which again is link to /mnt/shell/emulated/0, which is the internal storage fused to /data: /data/media/0.
But some how ES file explorer can not handle it. In ESFileExplorer in my B309, it show /sdcard as a *file* with a tiny link icon, instead of others normal one (like /vendor) which showed as a *folder* with a tiny link. And every time, when I open ESFileExplorer, it also report error, "/sdcard can not find" something like that. I have to go to its settings page, Directory Settings, and set "Home Directory" to "/storage/emulated/0", then the error is gone. For me, I changed it to /storage/sdcard1, which is my external sdcard.
Another side notes, if sometime your app (that requires root) complains can not write to storage, goto SuperSU settings, and disable "Mount namespace separation", this may help resolve lots of problem.
These is more info from the command line, I can not tell the different between /sdcard and /vendor, but ESFileExplorer can not open /sdcard
(when run these "ls" as non-root user, the result is same)
Code:
[email protected]:/ # ls -l sdcard
ls -l sdcard
lrwxrwxrwx root root 1970-01-01 00:20 sdcard -> /storage/emulated/legacy
[email protected]:/ # ls -l vendor
ls -l vendor
lrwxrwxrwx root root 1970-01-01 00:20 vendor -> /system/vendor
[email protected]:/ # ls -l sdcard/
ls -l sdcard/
drwxrwx--- root sdcard_r 2008-12-31 18:48 Alarms
drwxrwx--x root sdcard_r 2015-07-03 03:36 Android
...
[email protected]:/ # ls -l vendor/
ls -l vendor/
drwxr-xr-x root shell 2015-06-24 13:09 etc
drwxr-xr-x root shell 2015-06-24 13:09 firmware
...
PS, Just realized in the phone setting-storage, I can set default storage to "External", then after that /sdcard become normal as it is not link to fused FS anymore:
Code:
[email protected]:/ # ls -l /sdcard
ls -l /sdcard
lrwxrwxrwx root root 1970-01-01 04:15 sdcard -> /storage/sdcard1
[email protected]:/ # ls -l /storage
ls -l /storage
dr-xr-xr-x root root 1970-01-01 04:15 emulated
lrwxrwxrwx root root 1970-01-01 04:15 sdcard0 -> /storage/emulated/0
drwxrwxr-x root sdcard_rw 2015-07-03 12:50 sdcard1
drwx------ root root 1970-01-01 04:15 uicc0
drwx------ root root 1970-01-01 04:15 usbotg
Why did I not have any problems booting into fastboot, flashing TWRP-L through fastboot, booting directly into TWRP, enabling the read/write dialog option, then flashing SuperSu? TWRP survives, root worked, etc
Couldn't have been a more standard way of going about it.
Also, I had a problem with my external SD card being read only after lollipop update, but I think I fixed it by going to settings and changing default storage to external sd card and rebooting. Now both internal and external can be written to.
