[LG G5 back to Stock] [H850 Europe] [Full Wipe]

[wolfgart]

Just tried on my device H850 and other two EU Variant with success and no problem.

Prerequisites :

1. have just installed right G5 Drivers here
2. make a backup using LG Bridge (optional)
3. download and install right LGUP version here (if you have installed another one remove it before)
4. download and install H850 DLL file here
5. Download right KDZ for your variant. In this case we will use H85010c provided by @autoprime here

Here we go.

Installation guide:

1. Power Off device
2. By pressing Vol Up button connect device to your pc and wait Download Mode screen it appears on device
3. Start LGUP , check Bin file and select your KDZ

4. Select REFURBISH in "Process" panel
5. Close LGUP and open it again
6. click to START to begin Stock Clean Reflash
7. wait that in "Step" panel you have "Complete" status and don't disconnect device from pc until % is = 100%

Finish

oh wow, that is just amazing. I was holding off rooting my device till there is a way to get back to stock and now it seems we have a way.

Does the warning triangle/message disappears after stock flash ?

Because if you unlock bootloader, you can' t relock it

I've installed LG Up version you linked in windows 10, but process tab doesn't appear, so I cannot check refurbish or upgrade.

Problem is not LGUP version but your Windows.

You should clear you registry from all traces of previous LGUP versions, reboot, and reinstall him

Trying this on my H850, but LG UP shows it as model Unknown and won't let me Select it to continue. It says "You have to select a known model, please."

Ahh that was it, forgot the DLL.

In LG UP I chose the Upgrade option instead of Refurbish to see what would happen (hoping not to lose all my data and have to restore). Seems to have worked ok, went from 10a to 10c now. Everything working ok so far.

good news: this seems to have fixed the aux/headphone jack static problem in my car. Don't have to use a ground loop isolator any more.

Looks like that many guys do not read the guide

I managed to flash the KDZ file. But now, I'm not able to root it again.

fastboot boot twrp does not work (unknown command)
fastboot flash recovery twrp claims to be run successfully, but still the stock recovery is installed. Whcih means: everytime I try to get into recovery mode a full wipe is done. this is really annoying.

According to "fastboot getvar unlocked", the device is still unlocked and, due to this, the unlock image cannot be flashed again.

Do you know what I'm doing wrong here?

Edit: Done. The fifth time it worked. Nevermind. Thank you!
