LG G3 LS990 Hard Brick/Wont Turn On/No LED No Light/Black Screen - G3 Q&A, Help & Troubleshooting

hi, I tried T-Mobile version of CloudyG3 2.2 ROM on my LG G3 LS990, when it asked for a reboot, I rebooted it and since then its not turning on anymore, there is no LED, no screen, nothing. I tried many times to press and hold power button and combinations of volume up and down keys, no luck. Before the ROM update it had good amount of battery, more than 80%.
However when I pluck it in with my computer, Windows detects it as "LGE AndroidNet USB Serial Port (COM41)". Thus I got luck. I changed it to COM41 and tried to flash it ZV4 TOT using LG Flash Tool, but it says as below:
--------------------------------------------------
PID: NULL
IMEI: NULL
Model:
DLL: LS990
BIN: LS990ZV4_04.51101.TOT
SWV:
SWOV:
Model Information Check FAIL!
00000000
--------------------------------------------------
I guess the T-Mobile ROM might have updated its model number somewhere or did some changes. I used LG Flash Tool before and used ZV4 TOT to unlock my phone, and it was working fine with bare-pop ROM (LP 5.1). Then I thought to try CloudyG3 2.2 with another variant's ROM file since it doesn't have any for LS990 yet.
One more thing is the when the battery is removed and phone is connected to computer, there is a sign on the phone-screen, that says battery is not present. So the screen is fine I believe.
Thanks and will appreciate if someone can help to fix my issue.

Did anyone find a fix for this? My phone is in the same boat

Makes sense that your phone is bricked because Cloudy G3 currently does not support the LS990.
Keep trying to enter download mode.

I had the same, I edited the tot file, deleted the d855 (in your care ls990) and I avoided this error but it didn't flash.
I suggest you seek for the qhusb 9008 fix, boarddiag etc. It's actually pretty easy (but you have to open the device)

Have any of u used the guide here. http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359

Fixed through JTAG
I had it fixed from a guy using jtag. Had to pay him $30 though

LGD855 Changed to LS990 after flashing wrong rom.and wont go back

Hello Everyone I have a problem with my LG G3 which I have bought it recently was working nice but it had KitKat so I wanted to upgrade to lollipop but didn't know that LG G3 had different variant.
I've downloaded a wrong flash (LS990 sprint) and flashed it. so I lost the network and I noticed that the imei has changed. and I don't have the original IMEI of the phone ( the sticker on the back of phone is for D855 16GB not for D855 32GB).so I think its not the original IMEI.
After bricking the phone I've opened it and noticed that it was D855 written on the motherboard.
when trying to flash the original D855 rom it doesn't work (flashed it using the crossDLL method and using the Hex Method By changing D855 to LS990 to make the flash tool think Its LS990) the flash pass on both methods but i'm stuck on LG logo.
send it to some repairing services here in my country but they didn't fix it they thought its sprint so they flashed PrimeGSM but still no network.
I think I should change the IMEI before flashing D855 or something.
please Help me I've looked all over the NET but find no solution to this problem.
If you need more informations ask me. Help me as soon as possible this is the only phone that I have.
Did you ever figure out how to fix this? I have a ls990 which was flashed with PrimeGSM and is now detected as a d855... I have been trying to get this working for the last two days with no luck
Reply
Hello
What is the problem that you are facing ?
Is it a network problem or what ?
Primegsm is ported from d855 so i think it will show D855 on any lg g3 that does'nt mean that your phone detected as d855.
Make sure your phone is ls990 or another variant
And which country and carrier ? So i can help you.
I basically have a soft bricked phone - no OS as all. I am in New Zealand running on the Vodafone network.
I was using PrimeGSM and it was working fine but decided to go back to the stock ZV8, when running through LG Flash Tool I noticed Download mode was showing the model as a D855 and would not accept the LS990 DLL - I then made the mistake of using the generic DLL with a D855 image which started a boot loop - then made more mistakes and ended up with no OS and stuck at the LG logo.
At this stage I am able to get to fastboot and use fastboot boot to get into TWRP but cannot do much from there, I also have to use the D855 TWRP image as the LS990 fails with a device tree issue. fastboot will not erase any partitions or flash any images manually. Using terminal in TWRP I am able to browse the partition though but cannot mount the SD card or use adb to push or pull (fails with error closed)
I stuffed up quite a few times along the way but sure I can recover from it since I still have quite a bit of access to the device...
I managed to get my phone going again by following a guide I found in the forum, I am pretty sure it would solve the ops issue as well.
Really quick and easy, I just bridged the points with a needle and copper cable.

No signal, wrong country version

Hi,
I have a problem with my LG G3. The phone shows the well known message "Current version is not available for user. Can't find matched cust for NT-code mcc/mnc[], subset[]". If I insert SIM, the phone won't connect to any network.
This is how it happened:
I bought the phone form Aliexpress as refurbished. It came with Android 4.4. It could not find any update for my ROM. So I decided to root it and install CM13. But during the rooting process the phone got hard bricked. I had to follow the guide with shorting pins and Qualcomm driver to restore the phone. Unfortunately I didn't have the original ROM. So I flashed files from LGD855AT-00-V10e-EUR TOT. Then I was at least able to get to download mode and flashed a European Lollipop ROM with LGUP.
Since then I'm getting this error message no matter which ROM I tried. According to IMEI the phone location code is A6GBTN. So I even tried to install a UK ROM without any success.
I think the fault might be caused by the fact that during unbricking I flashed also do misc.img partition. And now the data in it don't match with my phone. Is it possible? What should I try?
Thank you.

Unable to access fastboot

Hi,
I just got a refurbished LG G4, and i'm unable to reboot to fastboot mode. I want to install TWRP and LineageOS. Before that i have to unlock the bootloader.
I followed this guide : [HOWTO][H815] Complete Guide to Unlock Bootloader + TWRP + Root + Xposed + ViperFX . I'm stuck at "1. Unlocking the bootloader officially" -> viii) ...adb reboot bootloader etc...
I tried on Windows and GNU/Linux "adb reboot bootloader" and "adb reboot-bootloader", with and without administrator/super-user right without any success....
The phone reboot to Android. However the phone can reboot in recovery and download mode.
The phone is still in android 5.1, and come from T Mobile (the phone suggest upgrade from T Mobile).
One strange thing is the dmesg usb connection log on GNU/Linux :
Code:
[195563.124097] usb 2-2: new high-speed USB device number 43 using ehci-pci
[195563.257487] usb 2-2: New USB device found, idVendor=1004, idProduct=631d
[195563.257498] usb 2-2: New USB device strings: Mfr=1, Product=2, SerialNumber=3
[195563.257506] usb 2-2: Product: LGE Android Phone
[195563.257512] usb 2-2: Manufacturer: LG Electronics Inc.
[195563.257518] usb 2-2: SerialNumber: LGH81029e8b9d6
The serial number start with H810, and the phone is labelled H815 in the stickers under the battery, and on the info on Android...
What can I try to get the fastboot mode?
The refurbished phone says "H810" on download mode. The IMEI was modified too to appear be a H815, as the stickers etc... The phone is counterfeit...
Someone have/had the same problem?
Settings -> developer options -> OEM unlock enabled?

frankenphone maybe someparts from h810 and some from h815 and manipulated or edited software.. we had this in G2 alot. only wasy to find out was by looking at motherboard its printed what variant it is only looking at it physically. mean to take out on you hand and read the number model.

I requested a refund. The vendor falsified the IMEI and model number. The Android image seems to be frankenstein-like too. It proposes me to upgrade with "T-Mobile" (and fail at reboot), and the default welcome page on the web browser is att.net (after a complete wipe out)...
I don't know how to solve this problem. I need more LTE band (working but it's poor comparing to my Xperia Z1c). I have the band 7, but I need band 3, 20 and 28.
1. Which method (unlock bootloader, install TWRP, etc...) i must use the one for H815 or the one for the H810 ? Which image of Lineage OS ? Logically the H810 one?
2. Is there a way to revert back the phone to its original model and IMEI ?
3. Finding the original IMEI? Maybe with the original SN?

I tried LG Bridge, and it detect the phone has a H815. When it tries to upgrade the phone, on the reboot, on download mode, the phone show information like H810 H81010o, and stay stuck here. The software on windows report a fail.
"LG Phone From" report a H815, with the IMEI on the label.
I read that it's possible to modify the model name(here on XDA) and the IMEI (QPSK or LG "something" by Octopuss). Seem's that some vendor in Aliexpress are not very straight...

Is there a way to revert back the phone to the correct model (H810) ?
I read this Lg G4 F500L - Fixing and Converting to International H815 Model
The solution is to modify the TOT file? How to do that ?

Did it. The discussion is on the way.
Opened the phone, the mainboard is labeled VS986.
So :
-Download mode claim H81010o
-Android show H815
-Mainboard is labeled VS986
So my phone is a VS986 (ie the mainboard). Is there a way to make it a VS986 for Android and Download Mode, like the mainboard was originally?

I tried the KDZ for Verizon (VS986). LGUP fail because the model reported is H815. I will try with "LG Flash Tool 2014".
Another solution could be writing directly the eMMC with eMMC DL Tool. I didn't find the VS986 bin file for now.
I successfully flashed the phone with "LG Flash Tool 2014".. It's now a VS986 (claimed by android) and as labeled on the motherboard.

is all working .. too bad you wont have unlocked bootloader.
Yes, and :
LTE isn't working (verizon limitation)
Sticker labelled H815
What I've found out about my G4 Frankenphone so far:
- sealed box said LG G4 'dual LTE'
- sticker on phone under battery says H811 and has a valid corresponding IMEI
- phone model in settings/device info is H810 with IMEI 0! :crying:
- download mode screen is in Korean with some mention of F500L v11d...
- the phone came rooted running LP
- it is registered on my network, working 4G LTE!
I've been hoping to custom OS and reinstate a sensible IMEI but from everything I've read and not been able to do (can't flash anything and always coming across 'barriers') and to avoid bricking the phone, I am giving up. I have contacted the vendor and told him to find a replacement, clean G4 or clean G3. Seems to me that the G3 is a lot more versatile in terms of the support, especially here, for it. I shall miss the spec. of my G4 and it's greeeat camera!
- unless someone can convince me otherwise or point me to a G4 FrankenRom link and successful instructions!

open phone . take out mother board .. and read plaque model. if sprint flash sprint KDZ and LGUP. if H815 then do that .. thats the only way to be sure.
U have a refurbished model.Go to nearest mobile repair shop & take out your motherboard to see what model no is written on this.Then flash a rom accoringly. Don't flash any other rom just by assuming else you will brick your device.
Yes my phone is refurbished...
But how to flash the rom?
If I found it to be a sprint version and flash a sprint rom ...it will be locked?I am using phone in India...
Any chance to root the phone and install twrp?
Then flash a custom rom?
Please help...

Most probably it will be locked cause most higher Android versions LG has blocked rooting or unlocking..But you can always browse few threads.
Mine is also a refurbished model with F500L motherboard,LS911 body & had H815 global rom installed out of the box.I am currently on F500L Nougat locked & unrooted..I have tried almost every method.It failed to root & even to enter fast boot.
If you get your proper model no on motherboard then just flash the rom with ToT flasher in download mode with respective DLL.

Your network is locked?
You cant unlock it?
Can we degrade our Os to lollipop to get root?
Even I cant turn on the Enable OEM unlock under the developer mode...
Any more advices?
Please help.....
I have tried almost all h815 ans ls991 roms with all flashing methods but still unable to successfully flash my device...lg tot flash tool always show dl error after 4 to 6 percent of flashing...
Please help
Any idea's?
Pick the phone, and send it to the place where you bought it. If you have warranty the repair is free, if not, then you must pay sadly.
Still no solution, I even cannot enable OEM unlock under developer options...
It automatically disables it...
Please help
Just experienced this issue after changing sim card... Call and Camera stopped working over and over again.
How I solved it: Go to the specific app that is causing you trouble, and clear cache/files (too bad I only found this after 3 factory resets).
Maybe it will help ... LG G4 CAM

[D855] Phone not flashable

Hello, I have an international D855 32GB that I used with many roms.
After one flash (probably fulmics) I noticed bluetooth and wifi aren't working anymore.
Now I'm trying to flash back to stock because it seems to me a problem with software ( i checked and the wireless cable is firmly in position).
But when i try every method I find the phone seems to be not flashable (by PC)...
If I check my IMEI it seems OK (IMEI SV it's 00 I don't know if it's normal).
When I try to use LGUP it sees com port 41, d855 but it reports "model unknown".
With LG Flash tool it says that model info aren't recoverable, it doesn't see IMEI or other codes.
With LG FlashTool2014 it says wrong model info, and refuse to flash it.
There is a way with I can force the flash even if the model isn't recognized?
I'm sure that I'm using the correct tot and kdz files.
The phone actually works pretty well (except for wifi and bluetooth and maybe mobile networks, and I'm able to flash things from twrp successfully, but I wanted to make a complete reflash from the PC), or maybe there are files that I can flash trough twrp to be sure to reflash everything? Also, i have my IMEI backup that I made before the first flash of the phone.
Thank you in advance if you can help me
