I'm trying to unlock the bootloader of an H815 on Android 6.0 V20d-EUR-XX. Bought it second hand so I have no idea what has been done prior to me. I'm following the official LG guide on this but when I do "adb reboot bootloader" the phone simply reboots and goes into Android again. Been looking for a solution for the last hour. Do you think this could be a solution? Thank you

i want to update my Unlocked AT&T LG V10 to the latest update H90021W. i tried using lg bridge but it prompts me to update from the update center from the phone itself. when i try to update from the phone, it shows "Device is up to date".

my question is that if i update via flashing the firmware file, will my device be relocked by AT&T? i live outside USA and Etisalat as my carrier. i have already downloaded the .kdz file for v21w software. i worried whether the device will get relocked by AT&T. help me out guys.

also i am getting a pretty poor battery out of my V10. wondering whether the new update would give me a better battery life.

Find a way to unbrick your devices first.

For eg, my g3 - qualcomm qh-usb method.

1-Followed the guide and flashed all files without LAF partition.

2-Flashed sbl1 last and Rebooted and pressed vol+ and phone booted in fastboot.

3-Erased all partitions excepting rct (can't flash it via fastboot but kept old v10a from tot file).

4-Flashed all partitions from a newer kdz file (find a kdz file extractor here on forum).

I've got several files from the kdz and flashed each file in his partition. If multiple files for 1 partition flash it in the same partition:

eg: cust_1 and cust_2.img goes in cust partition. You don't need to flash system. Now you have a working download mode and your phone should be detected in LGUp

Make sure you download KDZ for your IMEI region: devtester dot ro/projects/lg-firmwares/

This is how i got my phone detected in lg up

however still got LAF READ ERROR
[G4 Q&A, Help & Troubleshooting] retsam000:
thanks for your answer, devtester doesn't have any results for my imei and when searching manually there is either no download website linked or the link is dead. sometimes i get forwarded to a website that is just plain white and a download doesn't pop up, i've tried multiple browsers of course.
[G4 Q&A, Help & Troubleshooting] Bican:
Then check your phone label and motherboard to be sure wich model you should download and after that follow my steps.

After i used boarddiag I could not get detected in LGUp.

Short verision:

1-Get in fastboot by any means (I told you how I've got)

2-Erase all partitions

3-Flash them from a fresh KDZ for your phone

4-Reboot and boot to Download Mode

Follow this to get a working Dlink from devtester: http://xdaforums.com/showthread.php?p=52258542#post52258542
[G4 Q&A, Help & Troubleshooting] retsam000:
Honestly all I could take away from your guide is that I can download kdz files from devtester.

One question.

I have H815 it was rooted by me and worked for 2 years with custom roms.

It broke down and I send it to repair shop (hardware issue). They unnecessary reinstalled Stock rom 5.1. Its not official repair shop.

Only issue i have now is that official updates dont work. I want to put it to 6.0MM and give it to family member. Updates download and after reboot it got stuck at 4% or 5% fails and reboot.

When i launch LG Support tool. It says Version: H81510b , and message says no updates for H81520G???? VEry strange. H81510b is in mobile settings software info. Could they installed the wrong stock rom.

So i decided to install KDZ. But there is no MM KDZ for H81510b.

My question is. Can install some other H815??? rom on my H815 like MM with codename H81520G/20D or something.

I'm trying to use this to add a pre-rooted 13b system img to my newly made stock 13b system. Couple issues i'm having are the fact that there are a couple different sets of instructions that overlap and it's a little sketchy. First ? is how can I get the img to work on lgup, it's obviously not a kdz or tot or zip file. If I could find a kdz of a rooted system it would be great but no luck. The 2 offered in the walk through are a tar and a 7zip that turns into system image when opened. Another issue is would I run this as fake ota since I have 13b already and am flashing a modified copy of same version.

Any help would be cool, thanks!!

Well I just tried making a zip file out of the system img and that didn't work as ota or refurbish. Errored at 9% with 0% started on the phone thank god so no brick or boot loop. Think the rooted system image is corrupt because I noticed I couldn't mount or open the root of the image in file manager earlier.

Hello,

Hoping I can get some direction as well for downgrading and then rooting my LG g4. I have gone through this & this guide but still have some questions.

I have a LG G4 H812 [Telus carrier] running soft ver H81220u with Marshmallow 6.0. Which KDz file I actually need to revert to lollipop ?

I have found this file [Canada TELUS H81210F.kdz].

Can I use this file with LGUP tool while selecting refurbished ?
