Summoning Those with T-Mobile V521!

I'm trying to make an AOSP ROM, and while doing so, I now have a dysfunctional bootloader. If your tablet is rooted, please duplicate the boot.img from your system and share it with me. Would very much appreciate.

Instructions:
Use CMD and paste these 2 lines:
adb shell "dd if=/dev/block/platform/soc.0/by-name/boot of=/sdcard/boot.img"
adb pull /sdcard/boot.img

Then from ADB directory, upload to somewhere easily accessible.

Does it matter if we have updated to 7.0 or not? I'm rooted and have updated to 7.0 and would be happy to help.

 

[mr_verystock]

That would actually be a good idea. The ROM is supposed to be 7.0.0 anyways.

 

[Munns86]

Running the first command comes up as " no such file or directory"

 

[mr_verystock]

Do you already have ADB?

Do you already have ADB?

Yep. I do adb devices to make sure it recognizes the tablet and all is good there.

Maybe so I'm the same page i just open up ADB as normal : open the command prompt in my platform tools. I paste the first line in : adb shell "dd if=/dev/block/platform/soc.0/by-name/boot of=/sdcard/boot.img" I get no file or directory.

Unable to get the dumb file:
adb shell "dd if=/dev/block/platform/soc.0/by-name/boot of=/sdcard/boot.img"
dd: /dev/block/platform/soc.0/by-name/boot: No such file or directory

Edit: does a backup from the recovery could make the task done ? I backup the boot from the TWRP and I get a file of 32Mb with the name: boot.emmc.win

 

[mr_verystock]

adb shell
cd /dev/block/platform
ls

And tell me the output. I appreciate your help!

Nothing, it returns an empty result

Unusual... Normally there's soc.0 or msm_sdcc.1.

That command never worked for me on this tablet. Yes the default kernels is 32mb.
You can get it from twrp backup as .win and then rename it (if it is not compressed) or use AUT or SuperR's kitchen to obtain it.
Another method would be flashifire>backup.
Im still on MM so I can not help you.

the stock files I extracted from stock kdz file using WindowsLGFirmwareExtract-1.2.6.1-Release
