Hello i have a problem with a friends LG G2 I flashed it lolipop 5.1 and then i wiped the whole internal storage clean and installed new firmware on it i tried flashing 4.4 the second time then the phone did not boot up and the screen was stuck to an error message cant quite remember it.
Anyway my friend sent it to lg and they said to him that the phone was double flashed and it could not be fixed... I need to know if i can recover the phone and if so detailed steps if possible.
Thank you very much (The phone has access to TWRP recovery.)
Please guys it is very important i need help with the matter
It can be unbricked. Your problem was probably flashing wrong bootstack since you got security boot error.
First, if you can get into download mode, do tot/kdz. There is guide here on xda

Hi there,
I realy need your help on my problems with the G2 32GB D802.
I bought it on ebay and instead of getting it from GB it came from HongKong and I didn't think about it that it does not have a european ROM.
First I wanted to root and flash custom recovery and cloudyG3 rom. After rooting with ioroot and installing the TWRP I stuck in the fastboot mode. First problem I did not make a backup because I never reached TWRP. Download mode only appeared for a second an then disappeared again.
After a lot of searching I found that probably the 802autorec.apk was wrong, since I don't have a european model. So I installed via fastboot a laf.img for a D800. After that the download mode was working again and I installed different roms via flashtool2014. The installation worked again but after rebooting the phone I had a lot of trouble with it. That the reason for trying different roms as I sad befor.
First, the fingertip points at different areas of the screen but not there where you are touching the screen. So you can not reach the buttons or write on the keyboard.
Second, after connection to pc I recognized that my 32GB model had only 10GB internal memory.
Finaly I can not use the phone. For me it seems that I burned my partitions and need your help to get it right again.
Please give me a chance.
Best regards an thanks for helping me.
p.s.: I tried to go to the settings menu in the phone and reached it after a lot of confusing taps on the screen. All the phones informations like IMEI and all the other disappeared. Something realy went wrong with it.
No one an idea how to get back to normal?

I now have the answer from the dealer that my G2 has the Firmware D80220B.
Just try and test it. Good luck.
@Angryyolk
I just ask myself how to enter engeniering mode?
Thanks for your help.
I walked one step forward now.
But there is still no solution for my problem. I found a link to LG "http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI" to get the information about the version of my stock ROM. Just replace IMEI by your real number and you will get it.
In the meantime I flashed the rom with flashtool but the screen behaviour is still the same.
I later rooted the phone with towleroot and then installed the correct autorek.apk for the D802. That worked properly. I reached TWRP but in fact of the weired screen behaviour I couldnt do something. I tried to fix my IMEI problem with QPST but this tool showed only empty tables on my PC when I connected my G2 with usb.
I tried an update of the screen firmware as posted above. The code that has to be entered on the dialer is 3845#*802# but it wont work for me since I can't enter "settings" the service menu. That's because of the weired behaviour.
Beste regards

Hello,
today I went to downgrade my L7 from Carbon ROM to V20A with CWM/ROOT by Homero using KDZ and when phone restarted after upgrade it got stuck at LG logo, so I tried flashing multiple times but it didn't succeed.
I couldn't even access the CWM, I tried almost all unbricking solutions.
Now I tried even with official LG Mobile Support Tool which updated firmware to V20D and it won't boot up.
a) Is there a way I can back my phone to get it working myself?
b) How much will the service cost as my warranty expired?
Thanks a lot!
Anybody?
Please, I really need to fix this device.
EDIT: Solved.
reinstall rom, maybe this can help u
Hello guys, I have a D802 phone and I was on Ressurection Remix 5.0 but since the official lollipop update was made avalaible, I wanted to return to stock and unroot so I could again use my warranty(for some weird reason they couldn't tell last time I took it there that it was rooted). Basically my problem is that every guide for going back to stock has the phone connected to the PC and use the flash tool. Well, I did that but when the mobile support tool opened for the upgrade, it couldn't find my phone. So I found a guide that showed you how to extract and rebuild a kdz file into a .zip. I tried that, used the UK d8023b rom ( A friend of mine who has a d802 as well, though unrooted, got the prompt to update through the pc suite and it updated his phone to d8023b, thats why i used that version), flashed it and I am now stuck in a bootloop. I have full access of recovery and adb but the phone isn't recognised by LG software. Can you please help me use my phone again? Going into download mode didn't work with the flash tool.
Hello Community! I hope I am right here, otherwise please just move this thread to where it belongs to, thanks!
I have a serious problem with my sgs 8 (950F). I flashed newest twrp, magisk, renovate-ice-g95x-r164 and no-verity-opt-encrypt-5.1. Everything worked fine and like a charme. I decided to update to a nightly version (worst decision ever) and before i was able to flash, twrp said: zip file corrupted. So I decided to go back to version 164 via the full backup i´ve made in twrp before. After the restore-process was finished, the device didn´t recognize the sim card anymore. So I tried to go back to stock firmware, which did not work since (after odin says pass) the firmware always stops at 32% and erases everything but the download mode on my phone. So I flashed twrp again, made a full wipe und data format and installed the renovate ice 164 again. After the boot, the sim card is detected and I also have to unlock it with the pin code. The problem is, that i can´t enter the network (Austria/Telering) and also I can´t search for any networks with my sim card, only emergency call is available. I am desperately looking for a solution to solve that problem and since I am no expert when it comes to details in flashing and the connections between hardware and software, i really could need help from experts. My guess is, that something is wrong with the modem. Can this be solved by flashing the mode new via odin? Stock firmware is not able to be flashed on my device, because of the error I mentioned above.
Thanks for you help and time!
I have an H872 on Havoc 4.4. I have upgraded to a Pixel and will be giving the H872 to my father-in-law. He will only be using it for phone calls - very unlikely he will text, and definitely won't use data. It will also be his first smart phone. Since the H872 is rooted, when it boots up it gives the warning display that the phone may be "Corrupted". I don't want to have to explain all that "root" stuff to him, etc... I want the phone as basic and simple as can be, hence , I want to reflash the stock firmware.
I am having troubles though. Booting the phone into download mode and starting LGUP fails to recognize the phone. I've tried with Uppercut as well and it says I'm missing a file in Apps/Roaming, etc...
Not sure the problem because I have reflashed stock many times with LGUP. Could it be that Havoc has changed the "identity" of the phone, or that it's on Android 11?
Any help to get this back to stock is much appreciated!
Got it figured out. Flashed back to an older TWRP (was on Orange Fox), flashed an old stock Oreo ROM, and then was able to flash kdz with LGUP.
