download lg bridge on pc and go error recovery. the tool will flash your phone with latest firmware and restore it to factory settings removing all modifications you have done to it.
Will this (LG Bridge) also work for H872?

Hello everyone! I am a beginner in the modification of Android, having rooted my g2 I followed a tutorial to fix the 4g on AMALBK in France. but I wondered if these changes could cause problems during updates? Can I do the update without fear via lg pc suite or OTA? I'd prefer not to have flashing process or complex changes . Please help me.
Sorry for my bad english.

If you modify the ROM you won't be able to OTA. That includes custom recovery, moving, renaming, or otherwise modifying anything in /system.

Thank you for the answer! How to find a phone like the factory? Can I update with lg pc suite?
I tried updating my phone via OTA the other day, but because I had TWRP recovery, when my system installed the updated, it would boot into TWRP, and.... that was basically it, could not update, had to rollback from a backup I took moments before. Then, in a stroke of genius, I used flashify to restore the original recovery and almost bricked my device.
Big tip for anyone in this situation...
When using flashify, use recovery IMAGE not zip, if you use the zip function, it has to boot into a recovery to use it, so the image file is the preferred method, in my opinion.
is this one flash able and stable, i have tried to use autorec to install recovery twrp, but i got security error and boot. also, i can even find the rom to restore it back ? any ideas ?
Rootable ? yes, you can use Kingroot it worked for me http://kingroot.fr.uptodown.com/android if this did not work try the PC version it will for sure.
is it stable ?, i cannot help on this.

Did you have a nandroid backup? If so, you can boot to twrp and restore. Or just go back to stock firmware.

thank you, but how do i get the original recovery file? i didnt find it.
with my pixel and oneplus 3t i was able to flash stock rom and this reseted recovery, too.
I already flashed the actual stock rom with twrp (https://forum.xda-developers.com/lg-g6/development/rom-eu-lg-h870-10n-rom-t3637828), but this zip was made to keep twrp. Now i´m wondering how to flash a full stock rom, inkl. recovery or just flash recovery....

Hey guys,
i still didn´t get it to work. Any Tipps for a LG Noob, how to get back to stock recovery?
plz give me a hint or throw a link in at me, If i´m missing something obvious :silly:
Can't you just install the official LG suite software on a desktop or laptop and then use that? It will probably detect the missing or "damaged" recovery and then automatically "repair".

Thank you. This did the Job.
Now I'm on stock rom with stock recovery, but the "fastboot oem lock" leads to a "corrupt device" that will not boot anymore. Can't the H870 (europe) be relocked, once it was unlocked via unlock.bin?
Isn't that the exact same procedure but then simply choosing "lock"?

i thought it was, but as a mentioned, it leads to a startscreen, that says: your device is corrupt and will not boot. after flashing the unlock bin it boots again

Is there a "lock.bin" file that can be fetched from the LG site maybe?
From the LG developer site:
4. Once unlocked, it cannot be undone.
There is no turning back once you have unlocked the bootloader. You will not be able to revert your phone to locked status.

I'm interested in buying a LG G6. Can you please explain a little bit more what you did to re-lock? Where did you get the kdz image (which region) and what steps did you do? I'm completely new to LG devices.
I just got this phone and I'm debating on unlocking the bootloader and rooting it and I was just curious if in the future I need to return it to stock (especially for selling it in the future) how do you go about doing that? Do you just flash one of the stock firmwares though TWRP like I found here? http://downloads.codefi.re/autoprime/LG/LG_G6/US997/US997-USA/US99714a
Then what do you do if that is correct? Also how do you relock the bootloader? I'm sorry if these are noob questions but I have been out of the modding game for a good while.

Just flash a kdz trough LGup and the phone will be completely stock, no twrp and no root. Then you have to only lock the bootloader by typing "fastboot oem lock". Don't run this command while you have twrp and root!
Ah, and the fact you have relocked the bootloader doesn't mean that you recovered the manufacturer warranty, LG can easily verify if you used the unlock bin.

I did some searching and found this. Is it the correct thing? http://rootmygalaxy.net/download-latest-lgup-tool-for-lg-devices-flash-tool/
Also just to be clear I unlock my bootloader, install TWRP and root the phone. If I ever want to go back to stock for selling the phone or whatever I just download the latest KDZ file like I linked to above and then I flash it to the phone and it will return everything back to stock? Then after that you just do the relock command and the bootloader is closed again?
I appreciate your help. I just to be super clear.

Pretty much yes, search for uppercut if you have driver problems with LGup, and for firmwares this is the best site to download them: https://lg-firmwares.com/lg-h870-firmwares/

Ok then
LGUP
Hi, so I started flashing the kdz on my LG G6 using LGUP and it starts, but then randomly quits out. It's recognising my device and the file is definitely the correct one. Any hints as to why it's not working?
EDIT: I managed to fix it, apparently Windows Defender was seeing Uppercut as a virus and stopping it from creating the files it needed to. So make sure you turn off Windows Defender when you do this.
My experience with returning phone to stock is bad. First unlocked bootloader, installed twrp, bootloader for havoc ROM and ROM itself..
Havoc 3.1 OK, but BT calling not working, so I decide go back to stock.
LGUP used without problem, but then camera neither flash ligh doesnt work anymore.
Last firmware for H870 used from official.
Have someone same shi t experience like me?
Trying everything, but no success.
So its not easy go back to stock again..
(My phone is H870 for EU)

It's a known problem, the A10 ROMs somehow mess with files needed for stock camera that aren't included in stock pie.
You have to flash Oreo bootloader and then 30b zip for the camera to work.
If that doesn't work flash Oreo kdz and update to Pie.

Problem finally solved!
Tried many times flash Oreo bootloader and then 30b(pie), 20a (oreo). With 30b everythings work except camera. With oreo 20a phone wasnt even bootup normally.. (after reset just screen with green android and message "No commands" appear. I used LG UP 1.14 with Uppercut.
Then after many unsuccesses I put phone to state where bootloop appeared and I thought about to throw it into garbage.
ADB shell and TWRP saved me... I was again able flash roms.
At the end I found some package with LG UP 1.14 and patch (so I could use it without Uppercut...there is a new LGUP_common DLL), and with this combination flash procedure worked smoothly.
BUT! I had to load nougat stock rom first (H87011i_00_OPEN_EU_OP_0108.kdz), which fix partitions in phone somehow (but there wasnt possibility upgrade higher). Everything, camera included was working with this rom..
Then I flash oreo stock rom (H87020a_00_OPEN_EU_OP_0423.kdz), and now It booted right (no "no command" during startup). Phone worked perfectly, and I used OTA upgrade to land on 30b pie last official update.. tadaaa
Hope it will help others with same problem..
Hello,
Recently i installed flumics rom on my phone and everything was fine but today i wanted to go back to stock rom and it seems i can't.
I installed the latest lg usb drivers and downloaded the latest lgup with uppercut
When i try to install the kdz file from the lgup everything is working fine and it finished 100% then the phone reboots and stucks at lg logo then after a while it reboots again and same thing stucks again.
ALso when i try to flash the kdz file again in the lgup it shows Fulmics rom 1.6
Tried to do a factory reset from lg recovery as well didn't help
Don't know how to turn off the device fully so i have some battery left.
Anyone can help me with this? do i need to send it back to lg?
If you have TWRP still just flash stock rom and bootloader

Sadly the kdz files i flashed restored the stock recovery.
Also i tried the lg bridge as well but that didn't work either.
I have left the phone doing its thing for more than 45 mins, i guess that is not normal.
Use LGUP and Uppercut to flash stock. Need drivers and put phone in download mode. It will find the port and then flash the firmware.

I downloaded 3 different kdz files for h870 and none of them worked.
The strange thing is why after i flash the kdzs the lgup shows Fulmics Rom v1.6 under the version category.
Is there any way to flash recovery via download mode?
Enter bootloader and try to flash twrp again. Then flash the stock rom and all will be fine.
