Based on my research you can do cat /proc/mtd to find the partition data. However that isn't in the sensation.
Based mike1986 partition thread I think this should work:
dd if=/dev/block/mmcblk0p20 of=boot.img bs=512
However anyone have a definite answer?
Hello everyone,
Can someone help me get some files from HTC one S s4 (US T-mobile) please?
Because my phone was broken, even cannot power on, cannot use adb as well. I need to collect a partition file from the phone.
Because once I saw some articles to solve this kind of trouble and want to have a try, but in lack of this partition file.
I just need those who have the same phone as mine can provide the file to me.
--------
adb shell su -c 'dd if=/dev/block/mmcblk0 of=/cache/partition0.bin bs=512 count=1'
adb shell su -c 'dd if=/dev/block/mmcblk0 of=/cache/partition0.bin bs=512 count=9'
--------
Can someone use these two command and send me two partition files please?
The final file is called "partition0.bin"
Each command can create one.
Thank you so much.:victory:
Hi, please do you know how to mount the full disk (all partitions) of an android device so that I can make a "dd" backup for another phone? (same model) Thanks for help!
ps: I'm now at the adb shell of the device, on ubuntu I have disks mounted as /dev/sda or /dev/sdb ... I have on my android device many many things in /dev and I don't find any sd* ; isn't the same thing?!
here is what i did in my sony xperia L and now i anything that can help kindly let me know
I rooted my device and then i officially unlocked my bootloader but after unlocking bootloader the phone was stuck in bootlooop so i installed stock recovery in the phone using flashtool and phone was just fine then. I did all this in order to change the partition of my phone.
Now i installed cwm recovery and after that phone i did the following commands
Open a command window: CMD, then get into shell:
adb shell
Once in shell, type:
umount /storage
parted /dev/block/mmcblk0
print
This prints out the partition information of your phone's memory chip
You will see the partition numbers in the first column, partition names in the last one,
in between you have the start/end memory index and the partition size
------start---end---size
...
31---1795---3506---1711---userdata
32---3506---7818---4312---sdcard
In the above output, consider the values indicated in italic as not to be changed !
Now calculate (open a spreadsheed if you like) the new value for the end of the userdata partition,
and use the same value for the start of the sdcard partition
On your sheet it should look something like this if you added 2048 to the userdata size
------start---end---size
31---1795---5554---3759---userdata
32---5554---7818---2264---sdcard
Remove userdata and sdcard partitions:
rm 31
rm 32
Create the new userdata and sdcard partitions:
mkpartfs logical ext2 1795 5554
name 31 userdata
mkpartfs logical fat32 5554 7818
name 32 sdcard
Exit parted to go to the adb shell again:
quit
userdata partition (31) needs to have ext4 file system
The following will do the ext2->ext4 conversion:
cd /storage/sdcard1/fs-utils
tune2fs -j /dev/block/mmcblk0p31
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p31
e2fsck -fpDC0 /dev/block/mmcblk0p31
Now when i restart my phone or even open the phone in cwm recovery it says cannot mount storage.
I tried installing the Rom again using flashtool it does not work and device gets disconnected probably coz now i am not able to mount my storage.
I tried to start adb shell and revert the changes i made in the above command in order to bring phone back to normal but now adb says no device is found.
I went to the customer service centre of sony they said they will change the motherboard.
Now my question is there any way i can fix my phone kindly tell me. I will really appreciate it Since i am not a software developer so i do not know any commands. Is there any way i can change my storage settings so they can be mounted again kindly let me know.

Just a question here, why did you want to change the partition of your phone?_? And no there isnt a way to revert thats a hard brick
Changing the motherboard will be the quickest method for Sony, which will not cause any trouble for them. You could ask the price for doing a low level format and restoring the partitions etc. Though I don't if they can do this in this case.
Hello,
Could someone having access to a rooted Zenfone 4 Pro do me a favour by dumping a partition on their device?
As root, execute the following commands:
Code:
# dump the sec partition to /data/local/tmp/sec.img
# it might be in /dev/block/platform/soc/<something>/by-name/
dd if=/dev/block/by-name/sec of=/data/local/tmp/sec.img
chmod 755 /data/local/tmp/sec.img
Then use ADB to retrieve the file from your device:
Code:
adb pull /data/local/tmp/sec.img
There is no personal data in this partition. It is either empty, or what's in it is the same for all devices.
Thanks a lot for the help!
You still need this?
