[Q] How to restore images which are backuped with dd via ADB

First of all I'm still exploring Androide and Linux = bit of a noob still
I rooted and then saved those images like this:
dd if=/dev/block/mmcblk0p10 of=/storage/extSdCard/backup/recovery/recovery_dd.img
dd if=/dev/block/mmcblk0p3 of=/storage/extSdCard/backup/efs/efs_dd.img
How can I restore them ?? (via ADB, Odin, Flashify)

In the opposite way
dd if=/storage/extSdCard/backup/recovery/recovery_dd.img of=/dev/block/mmcblk0p10
dd if=/storage/extSdCard/backup/efs/efs_dd.img of=/dev/block/mmcblk0p3

THX, didnt know that it is that simple. Can this be done during the device is in normal ON mode or do I have to set the device into a special mode after boot ?
How would you restare a system.img made with dd ? (I think ist not such a good idea to do it in normal ON mode ??)

How would you restore a system.img ?
a) extracted from StockROM package (does it need any conversion first ?)
b) made with dd
I think ist might not be a good idea to do it in normal ON mode ?? (Odin, ....???)

Pre-rooted v10D please

Hi1 my device running 5.1 V10C (H815). I want to flash prerooted v10c or D. Please give a guide to how to flash. Thanks

Do you have an image for it?
*edit*
Here's a pre-rooted H815 EUR 10D image I made:
https://www.androidfilehost.com/?fid=24052804347837030
With this image, SuperSu will ask to update. I'd recommend doing it.

Thank you. I am new on Lg. How can i flash this image safely?

Use thete steps: http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765
With this command (H815 specific):
Code:
dd if=/data/media/0/rootedsystem.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0
If you want to back up your current system partition first, use this command before running the above one:
Code:
dd if=/dev/block/mmcblk0 bs=8192 seek=55296 count=529920 of=/data/media/0/system.img
And if things go wrong, you can restore your backup with this:
Code:
dd if=/data/media/0/system.img bs=8192 seek=55296 count=529920 of=/dev/block/mmcblk0

If you have an unrooted system.img I could make it a rooted one.
Or follow the root injection method here to do it yourself (requires a linux OS):

If you don't back up your system partition, it means more effort required to re-flash a stock KDZ if it breaks. Or if you needed to revert to the previous version (v10c) or something.
You could also keep the rootedsystem.img I made on there and use that as a backup, assuming it works on your device.

Please provide partial eMMC dump!

Hello!
The fact is, I somehow hard-bricked my M9 (international version, MID: 0PJA10000, CID: originally HTC__A07, but probably any will be OK) - when flashing one of the firmwares it (I don't know why) flashed the 64 GB partition table instead of a 32 GB one and went into reboot, now I'm in 9008 BULK mode). My only hope now is to find an SDCard - on some of Qualcomm SoCs it is a safeguard - and try to boot from it - but for that I need an image of the working system.
Can somebody help me getting this - anyone with rooted 32 Gb version and S-OFF (S-ON dump didn't helped)? The command is very easy:
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1048576 count=768
If it doesn't work, just:
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1048576 count=768
Then just give me pls that 768 Mb backup.bin file (it shouldn't have any personal information).
Help me please! This is my last hope.

[solved] TWRP Bootloop after LineageOS update/OTA

Hi, i'm stuck on TWRP 2.8.7.1 after a failed attempts to update LineageOS via OTA.
I cannot boot in bootloader nor in system, it always shows TWRP.
I found everywhere that in this case you should use these command lines :
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
but it gives me "no such file or directory" error :
Code:
~ # dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd: can't open '/dev/block/platform/msm_sdcc.1/by-name/fota': No such file or directory
~ # ls /dev/block/platform/
7824900.sdhci 7864900.sdhci
These are the only files I have in /dev/block/platform/
I don't know why but I can't update TWRP via TWRP : when I try to flash the image it just proposes me to flash the boot partition (not the recovery).
What could I do ?

I forgot to mention I flashed the correct crackling LineageOS image afterward, and it worked, but I'm still blocked in TWRP.

I handled it !
I just changed the command line to :
Code:
dd if=/dev/zero of=/dev/block/platform/7824900.sdhci/by-name/fota
dd if=/dev/zero of=/dev/block/platform/7824900.sdhci/by-name/misc
Too bad I completely wiped all my phone trying to make things work. I hope it will be useful to someone !

Hello, same twrp loop with 3.0.0 or brick with twrp 3.0.3 by fastboot
I find "fastboot continue" to boot in system
I'm testing with last nightly,
after update twrp with playstore

Thanks for your message and knowledge on this matter. The force salutes you and is with you

I keep coming to this thread for the commands.

Thanks krodelabestiole

This finally saved me. I was trying the same two commands that you started with and got the same "no such directory..." error and your new commands worked. That was a tense few hours.

What's the need when you have twrp recovery to backup.
Moderator Edit:
I have deleted your quote of the entire OP (the post above this). There is no need to do this - apart from being unnecessary, it can cause issues for those members on limited bandwidth or when Mobile. Thanks for your future consideration.

TWRP is limited.
you can only take backup of system, data, cache & boot with TWRP recovery. you cannot take backup of nvram with twrp recovery. If you accidently wiped nvram data, you will lost all your device wireless functionality like wifi, radio, bluetooth & etc. so only this guide will going to help you.

You should specify this guide as being for the mtk variants, not all variants because the commands are not the same as the Qualcomm variants

Worked great, though there were no nvram partitions to back up on my metro model.
Nice to have a full stock backup just in case, thanks!
