I bought a D855 motherboard from ebay, and it arrived with Android 5.0 V20n.
I want to install LineageOS on it, so I need to root it first.
But every method I tried failed (probably not compatible with V20n).
So I tried to flash another stock ROM, but both LG Flash Tool and LG UP fail to recognize the device.
Any help would be greatly appreciated!
Did you manage to sort that out? I’m in exactly the same situation

I have a rooted LG G2 VS98012B with TWRP recovery and Cyanogenmod 11. I have tried this (http://forum.xda-developers.com/showthread.php?t=2432476) method, but I always get a "page error" at 49%. It doesn't brick my phone or anything, I just need it to work, since I'm returning the device to Best Buy in 2 days.
Follow this method instead...

I've done it myself quite a few times without issue.
Folks,
I gave my rooted (mahdi rom) ATT G2 to my teenage son seeing I was no longer using it. He said he tried to update the Mahdi ROM and now it is bricked. From my questioning him all I know is when he was installing the mahdi update, but he did not flash the D800 patch. Noticing there was a problem I think he tried to re-flash recovery or something. All he would get is "fastboot mode".
I think I am a pretty smart guy and have been on XDA for years flashing and what not with no issues - but this one has me stumped. These are the steps I have taken:
1) Finally got it into download mode and when I try to flash the tot file for ATT, it says incorrect model. Says the model is the D801 (t-mobile)! I was like what?
2) So I tried to flash the D801 tot and it seemed to work, but the flash would ultimately "Fail" in the LG Flash Tool. It would boot up into the t-mobile rom but I would get errors and reboots - very unstable. AND the IMEI was wiped!
Does anyone have any ideas what I can try next? I would like to somehow change the model back to the D800 and flash the ATT tot file. Maybe it is truly just bricked!?!?
Any help would appreciated! Thanks!

if you can successfully root device with towelroot(best choice since it is not device specific) then your best bet is to copy d800 build.prop(or to play it safe edit the build.prop model number from LG-D801 to LG-D800) into system/ give it rw-r--r-- pemissions and reboot into download mode, it should say you have d800 and you should be able to flash back to d800 tot(might want to be using d800 dll that ignores model check too just in case)
I have a d801 g2. When i flashed twrp i used d803 autorec because that is the only way to flash it on this model. So i installed cloudy g3 rom. Now i want to unroot back to stock lg d801. G2. First thing i did was i went into download mode and used lg mobile support tool to install stock rom. The phone recogized it as a d801. But when it went to the install it stopped at 49% and canceled the install. So how would i root it back to the d801 model. Im afraid if i install a d801 rom, it might brick my phone. Can someone help me?
I just bought a used lg g2. Guy had it unlocked and rooted and used Cyanogen mod for a d801, he used it on metro pcs. He said it was att phone. I verified by disassembling and check the MOBO. The imei also matches a d800. However when trying to return to stock on LG flash tools, I get an error saying device model is different. LG flash tools says its a d801 and im trying to install a d800 file. Anyone have any ideas?
Its running team win recovery v2.7.0.0
and CM 12-20150225 nightly d801
should I flash a d800 rom from recovery and then use lg flash tools?
Have you tried flashing the 801 kdz file? I've seen another thread on here about this specific problem. http://forum.xda-developers.com/lg-g2/help/version-g2-t3042262
No I havent. Just stock d800 tot
Fixed!
Flashed stock as per super sports thread and used the dll file at the bottom of the first post.

Are you sure you have original D802? Because many refurbished D802 are in fact either D800 or D801.
You may need to open it and see main board.
