Hi Casual_H4ck3r, thanks for the tutorial.
My LG Volt2 phone is bricked. I can access the phone on recovery and download mode.
Can you please post stock rom for this phone and a tutorial to apply it?
Click to expand...

By bricked, you mean bootloop? Does it power on, then off rapidly? Does it hang at a boot logo. If so, which one? There is a bootloader logo (before animation) and a boot logo (the animation with sound) And what did you do to cause this? I could fix it with this information. I plan dumping all the partitions soon. So like: System.img, Data.img boot.img and aboot.img (Those partitions are usually the ones that cause a brick)

Waiting to hear back.
Thanks!

oddly, this actually bricked my device.
it's stuck at the boot logo, not the bootloader logo. tried a cache and factory reset, nothing. :thinking:
any help highly appreciated.

This is weird because I tried it on two phones with no problems.
Can you give me your firmware you were on? LS751ZV(firmware number)

Also in the tutorial at the line:
Again:
ls tmp
[Enter] (Confirm the files are in there)

where it says /tmp/busybox
that's not another command, it's part of the sh script, did you run it correctly? If you repeat this process you have a chance of fixing it.
That's why I put the enter lines.

I'll try again, also do you have the boost mobile version or virgin mobile? I know there's two variants but I don't know if the difference would change much.

Want to try this, but, I need the partition block number.
Can you please post it?
Thanks.
I have a LG Volt 2.
Hangs on the boot screen, (lg logo screen).
There is a surprising lack of support for this phone. (Even on XDA).

Hello I went threw these steps fine everything done what it was suppose to but now on this line I am stuck dd if=/tmp/boot.img of=/dev/block/[boot.img ((((((((partition block number, posting tomorrow))))))
What do I put in place from partition block number and so on? I don't know coding very well but I think if I can figure that out it might fix my issue

I'm currently stuck on LS751ZV4 from rooting and messing with the system files to free up space. I rooted with Kingroot then used SuperSU Me to switch to SuperSU. Using Link2SD for storage management. I wouldnt mind helping in any way. I have worked on Cyanogenmod on other phones once the device tree was up. Let me know what I can do.

i do believe I just need the firmware and factory recovery and It should get me back up and running. Thanks for the repply

I tried couldn't get it to work but I'm sure I'm missing something. I've read read and read then I read some more gotta take a break from it for now I think. I didn't know what the boot partition number was from the above post. So I learned how to open a tot file and extract it to find the number but not sure which one to do what with. I will post results in the future. Thanks for your help.

Hi, thanks to you.
The phone is on a loop. When turn on it show the LG boot screen for some seconds, then it restart and show the screen again.

I bricked the phone deleting system app's after root the phone.

I tried to install an update from zip, but the phone says that the update I try to install is oldest than the phone have.

I need to know exactly what you did, Did you root using this method? Are you getting any errors? Besides the LG Logo? What apps did you install before experiencing this. Careful, some play store apps are infected and will, and can kill your device. Experience.

If you are using this unbrick guide, your phone should say something like:

-----------------
SECURE BOOT ERROR: boot
-----------------

Still looking for the block number? I'm sorry, I forgot all about it. I promise I'll get it up in 1-2 days.

Still need partition block number.

For the LG Volt 2 instead of using the standard:
Code: 
/dev/block/platform/msm_sdcc.1/by-name/
use
Code: 
/dev/block/bootdevice/by-name/

So to pull the boot file and save to SD use:
Code: 
dd if=/dev/block/bootdevice/by-name/boot of=/storage/external_SD/boot.img

Writing should work the same just swap the input file (if) and output file (of).

Here is the partition layout:
Code: 
shell@c90nas:/ $ ls -al /dev/block/bootdevice/by-name
