HI,
guys i was trying to work for a solution with recent root and recovery development and bricked my device. Even in bootloader mode i get Secure booting error. Has anyone fixed this for snapdragon 805 variant of LG G3 ? I know some of the users have got it working for 801 variant by sorting pins from the motherboard. I just need confirmation if anyone can provide
Thanx .
any one with anything?
Multiple threads little to no replies besides sensless info that ive already tried
CAN TOT METHOD WORK ON TMOBILES VARIANT G4 AND IF SO WHERES THE LINK FOR THE TOT FILE NOT KDZ!
Tmobile g4 forum is helpless after days and 100s views
this is my last hope. I Have a tmobile lg g4 model. I hapened to relock the bootloader while i was still on a rom and rooted with twrp, but i do have download mode and only download mode .I dont have a bootable o.s
Ive tried and tried and tried to get lg UP Tool which is a joke its not really a true unbrick tool cause if you bricked yourself on a rom and not the stock firmware its useless .All you get is device model unknown. This is supposedly cause custom roms are edited. Lg bridge does not work as a brick tool either it just states wether your firmware is up to date . The only hope was lg flash tool 2014 but that im told and seems to be outdated not compatible with any g4 on android 6.0.... Im at a loss here i can get into dload mode thats it the phone charges in download mode also and it also is recognized by pc meaning drivers are installed because lg mobile support tool sees my device and says its up to date.
s
Some members have been in my same scenario relocked bootloader with a rom and twrp with nothing but download mode and swear they fixed it with lg bridge tool using the update recovery error link within the tool.
Can anyone confirm if im screwed or if i am doing something wrong this is day 5 now im ready to toss the g4 in the trash for the sake of my sanity.
Closed at OP's request
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?

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?
Install LG Phone From and run it,maybe you'll get more information...

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!
Goodnight.
I have an LG G4 LS991 and use LGFlashTool2014.exe with the cse flash option with the kdz US99124a_00_0119.kdz.
Once the installation was over, the cell phone went out and died. does not enter download mode. does not go into fastboot. does not react to anything.
any solution?
thank you very much
sorry for the bad translation!

You flashed a US991 firmware on a ls991? Why? These are different models! LS991 is not US991.
Check what happens when connect it to your pc in the device manager. Do you see something like qhusb / qdl / 9008 device?

Hi @steadfasterX
the reason was because I am from Argentina and the LG buy it by ebay to the US, in Argentina the code of the model is different, and as the KDZ started with "US" I thought it was that, totally wrong.
and yes, Qualcomm HS-USB QDLoader 9008

Hello
I'm going to try it and commented how it went
thank you very much
I do contract work for a cellular dealer, and they've given me some demo units to set up as loaner units for client devices going out for service.
I've been able to disable and remove the Retail Mode application on most of the devices, but the G7 Thinq doesn't seem to allow it to be removed - it's effectively baked into the ROM (it can be stopped/disabled, but that doesn't allow for full access - each time the device is wiped it goes back into demo mode, something that's useless for a service loaner).
Since I'm in Canada I'm assuming that there's no bootloader unlock available so I'm stuck until this (hopefully) drops/releases? My knowledge in my time with devices leads me to understand that there's no way to remove an app that's baked in (although some Samsung devices have bloatware removal tools or ADB commands to help with this process, so I figured asking might be a long shot!)
Thanks in advance

After flashing the KDz did the retail mode gone ?
Do the demo units have a active modem?
Maby it's disable to prevent them from being sold to customers.
U probably nead to flash correct kdz if its a real fully functional unit..
The demo mode is activated automatically so stores can wipe a unit fast when costomers try to tamper with demo units.
Help me please
