Don't load a ROM not intended for your phone. Only lollipop can be rooted. User lgup to get to a lp ROM. Then do root injection for that ROM and freeze the updater.

Hi,

My second G4 went into boot loop mode today so I decided to flash the firmware and see if I can recover the device into a working condition.

I saw that the last update from Verizon was VS98626A so I downloaded the VS98626A_00_0615_ARB02.kdz file from the internet and began the flashing process using LGUP. Everything went smoothly, the phone showed progress and said the firmware was being flashed until it had to reboot the phone. When it reboots, the phone still goes back into boot loop mode.

Any ideas on how to fix this??

Hello,

All I was able to achieve was unlocking the bootloader. My phone has Android 6.0 V20h. Is it possible to root it? How? Could you help me, please? Thank you in advance.

Canadian H812 - I don't know the original carrier for downgrade

I've recently bought a used SIM-unlocked LG G4 which has already been upgraded to Marshmallow:

Android version: 6.0

Android security patch level: 2016-07-01

Baseband version: MPSS.BO.2.5.c3-00128-M8992FAAAANAZM-1

Kernel version: 3.10.84

Build number: MRA58K

Software version: H81220x

Based on my research:

1. Downgrade to one of the Canadian carrier-based Lollipop firmwares HERE using LGUP. (As I understand it, bootloader will remain locked on the H812 until it is rooted first)

2. Apply root procedure, re-upgrade to Marshmallow. (I haven't gotten this far yet)

My question pertains to the fact that I don't know which carrier-based firmware to apply, since I don't know the original carrier (before it was SIM unlocked) and I'm worried that applying the wrong Lollipop firmware would brick my phone. Also, based on the Software Info, I can't deduce the original carrier and/or LP firmware version.

HELP: does it matter which firmware I apply? If so, how can I figure out the original carrier/LP firmware version?

Thanks!!

Hi. I've just bought an used G4 for just 150€: It's an italian H815 with v20g-OPT2-HQ . I'm a noob with this device and so I have some questions:

1) is there actually a way to root without void warranty or a way to restore warranty bit? (i've found a lot of guides on the forum but that void warranty)

2) I'm interested in CM14... what are the best camera apps for this device on Aosp rom?

3) if not possible on MM, can i downgrade to lollipop and than root without mess warranty?

This phone was repaired 2 month ago from the bootloop issue...and for this reason I'm a bit worried. But i"ve read that since march repairs are permanent

[G4 Q&A, Help & Troubleshooting] steadfasterX:
No other way. There is a thread where you can save your current locked state to be able to re-lock your device again. This way you can go official unlock and then lock it again whenever you wish.

Haven't tested this but it may is worth to try it.

[G4 Q&A, Help & Troubleshooting] stinka318:
Thanks for letting me know I didn't think there is any way to flash a kernel to unlock the bootloader.....
[G4 Q&A, Help & Troubleshooting] steadfasterX:
Flashing another kernel will 100% fail because it has to be signed by a private LG key.

As no one other than LG has this key you will get a secure boot error leaving you with a soft bricked device.

Search for TWRP-in-FIsH and "android FIsH" which will workaround this. Atm for TWRP only. Maybe more to come..

[G4 Q&A, Help & Troubleshooting] br0adband:
Have you bothered to look at the camera lens cover on the back to see if it's damaged, or perhaps there's some dust or debris under that lens cover - the actual lens of the camera assembly is underneath the glass lens cover that you can touch on the back of the G4. If that's dirty or scratched on the outside, or dirty or scratched on the inside you can remove that lens cover assembly with two screws and attempt to clean off that glass on the inside and outside but you need to be careful doing it.

If you do decide to remove the lens cover assembly BE VERY CAREFUL not to touch the actual camera lens assembly in any manner - if you do all this and you've still got blurry or foggy images it's possible that the previous owner took that lens cover off and touched the physical lens of the camera assembly and there's some oil from his/her skin on the lens which will be somewhat difficult to remove, a very very soft chamois or microfiber cloth would be recommended and the very lightest of touches could do it.

You've only got one post here so your image attachments aren't showing up and you won't be able to post image links to other sites till you've made at least 10 posts. For the record so you'll know what I'm talking about this is the lens cover assembly:

and this is the actual physical lens of the camera itself:

Software wouldn't cause blurriness or fuzzy/foggy images unless somehow you have some kind of filter enabled (which the stock camera doesn't have of course) - some filters in third party apps can "add" such effects but, the only logical reason for it to happen would be either the lens cover assembly has dirt and smudges on it or the physical lens does.

Hope this helps...

Model number changes from H815 to H815TR

Hello guys, recently I flashed a vodafone branded v20L firmware on my LG G4 H815 version. Upon this step, my model number in hardware version shows H815TR while my actual model number is H815, which other third parties are verifying as such.

Initially I updated to MM(v20H) using LG Bridge, which is when I started having this model number conflict and now whenever I make/receive calls, the other party does not hear me, reportedly they hear static or muffled or nothing at the other end.

Ever since, I cannot clearly make calls without having a peace of mind.

Hi

I'm running the latest version of LineageOS 14 on my H815 and I've been having some issues with my data connection for a few weeks now.

I've tried wiping and flashing the OS again, but it didn't fix it.

What happens is that after my phone disconnects from WiFi, most of the time it doesn't connect to cellular data internet.

I have to reboot the phone in order to get it to connect again. Soft restart doesn't do it, have to do a normal restart.

If I have WiFi disabled and only use cellular data, it works fine, but I have limited bandwidth and the battery seems to be draining faster on cellular data.

Any ideas? Thanks for reading.

Hi all,

I need a bit of help,

the other day I flashed the stock nougat rom v29a, but after I flashed this i couldn,t flash twrp anymore. So thought it was a good idea to downgrade again and tried to flash a marshmallow kdz with the lg tool, but unfortunately it gave me an error at 25% of the process.

when I boot the phone now it boots in download mode, however I am able to boot in fastboot mode.

I have tried to flash the v29 nougat version via fastboot and it looked ok during the process but when I was finished and rebooted it booted back into download mode, tried to flash twrp but unable to boot twrp. I guess i need a nougat kdz file to be able to flash it via lgup of lg flashtool.

or is it possible to flash a rom via the fastboot commands and if yes how to.

LG G4 Unable to flash Stock ROM

I have LG G4 and I flashed (upgraded) it through LGUP from 5.1 to 6.0 a couple of days back. This is what has happened.

Before Flashing:

Hardware - LG-H815T

Android - 5.1

Software - H81510p

Baseband - MPSS.BO.2.5.c3-00072-M8992FAAAANAZM-1

Kernel - 3.10.49

Build Number - LMY47D

IMEI - 357766060879504

After Flashing:

Hardware - LG-H818

Android - 6.0

Software - V20a-OPT2-HQ

Baseband - MPSS.BO.2.5.c3-00101-M8992FAAAANAZM-1

Kernel - 3.10.84

Build Number - MRA58K

IMEI - Same

This is what the problems are:

1. The phone turns on but the screen stays black all the time. There is one way to turn on the screen and that is by removing the battery and plugging it to the usb cable and when the screen blinks for the missing battery indication, holding down the power button and inserting the battery. This way the phone turns on as if it has no issues.

2. The internal storage is showing 22gb instead of 32gb.

3. I am unable to flash (upgrade or refurbish) the phone through LG Flash Tool 2014, LGUP and LG Bridge. All softwares partially work through the process and according to my analysis give an error at the point after establishing connection with the mobile when its the time to access the internal storage for writing system files on the phone's storage.

4. I am unable to conclude the model number of the phone because before flashing it was H815T, after flashing it is H818 and when I connect it to LG Bridge, it shows the connected phone as F500K.

5. I tried to unlock the bootloader of the phone by visiting the LG Developer site and when I came down to filling in the information of the phone like IMEI and Device ID derived from the instructions outlined, it does not accept H815 as the model number against the Device ID of my phone and secondly does not list H818 and F500K in the dropdown options.

I don't know what wrong have I done in my life to end up in a situation like this???
