My intention is to list all physical partitions of /dev/block/mmcblk0 but outputs the following:
Code:
# fdisk -l /dev/block/mmcblk0
sh: fdisk: not found
Any idea about how to install such fdisk, cfdisk, parted or alternative command? Apparently it is not shipped by default.
Note: Superuser is installed.

Are you sure you want to use fdisk? Maybe you should read what fdisk does...

I had fdisk installed, but was version 1.17.1 which hadn't the fdisk applet. now I've got the BusyBox Pro 1.20.0 from market and does have it, just what I needed.
However, I haven't found what I am looking for. There seems to be only one partition, while I am looking for all the ones corresponding to efs, data, system, misc, boot, recovery and so on. Any ideas on that?
And yes, I used fdisk before on linux and cfdisk on freebsd so I feel quite comfortable with it.

Sorry, I missed the -l flag in your image, and for some reason I didn't process what you were looking for exactly.
Use the "df" command.
What are you trying to figure out exactly? Just a list of the partitions or sizes or something else...
Here is a list of the partitions and what they are used for

Is there where linux/ubuntu is installed with some market installers?
How to get the size (dynamic, I mean kB, MB, etc) of all partitions? Why partitions won't shop up in mmcblk0 directly?

Hi,
This is a modified Super Wipe script from ARHD.It will wipe cache ,data and system.
These are mount points used:
For U,P,Sola:
/dev/block/mmcblk0p10 system
/dev/block/mmcblk0p11 data
/dev/block/mmcblk0p12 cache
For S,Acro S:
/dev/block/mmcblk0p12 system
/dev/block/mmcblk0p14 data
/dev/block/mmcblk0p13 cache
If it is different for your device do not use this!
Download:
Super_Wipe_NXT_U_P_Sola.zip
Super_Wipe_NXT_S_acroS
Install this through CWM.
Use at your own risk!
Do you know the mount points for Xperia S ?

data,system,cache already done.And dalvik,battery is inside data.So already done.
this is a new idea,but not ok yet,just for suggest
(sorry for my poor english )
precondition:have root BEFORE update to r5a,(and NOT use ""double flash")
background:tablet s have 2 system partition,but only one is used.if your first system boot fail,system will try to boot use 2nd one
detail:
as precondition,you have root files in 2nd(backup) system,
so todo is try make system boot fail,then it will boot to backup system,
in backup system(have root) mount 1st partition and add root files
boot back to 1st system,
now you should have root
so how to make system boot fail(success flag not set)is the largest problem
my opinion is use reset button,break boot in right time.(near sony logo show)
and in more step, decompilation bin sysmount maybe get more info.
/init.nbx03.rc
Code:
on fs
wait /dev/block/mmcblk0p2
setprop ro.crypto.tmpfs_options size=128m,mode=0771,uid=1000,gid=1000
wait /dev/block/mmcblk0p3

Interesting, have you tried?

Hey guys, i have managed to root my Sony Tablet S (sgpt111gb/s) with the KingRoot app which you can download from the link below. You download APK on your device and install it as you would do normally and just run it and watch the show! I have to say that latest version of KingRoot DID NOT WORK with ver. 4.0.3 r5a currently installed on my tablet s but i've downloaded ''kingroot_global'' (link below) and it worked like a charm! My Sony Table S is now rooted
P.S. THIS ALSO WORKS FOR ALL OTHER ANDROID TABLETS/PHONES!
Link: kingroot dot net download or look for version 4.9.6_C151_B299....:fingers-crossed:
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

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

Still no love. 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>

# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

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:

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
