you were on kit kat and flashed a stock based LP rom ? not sure but didnt you have to be on stock LP then flash cloudy.
maybe flash a KDZ theres flasjable ones as zip for LP.
what i done from kitkat is
root/autorec. update twrp 2.8.7.3/bootstacks 5.02. bumped KK. you know you must reboot recovery into recovery again from recovery to take effect. during update of twrp and bootsacks then flash LP KDZ stock. then just wipe and flash cloudy.

Cheers managed to flash cloudy g2.2 over it,
Gps is terrible though

Stuck on LG logo after ROM flash

So i have a jdi panel d800 g2 ( iwas on 20k). i rooted with ioroot and installed TWRP then flashed a jdi KK kernel to avoid white lines. Then i followed the steps to install g3 rom. cleared memory etc and flashed baseband. when i flashed the g3 rom it seemed to go well and then asked me to set it up by choosing my carrier and such. when it was finished it asked me to reboot and then proceeded to get stuck on the lg logo.. so i flashed baack to 20c and got the ota update to 20y did everything again except install the Baseband and rom... how can i get it on right? couldnt find advice on cloudyg3 rom thread... any help appreciated!

Tired and annoyed, ROM help.

So, first got my LG G2. Was on 4.4.2. Managed to get custom recovery on it, cool. Attempted flashing resurrection remix. Success, bootloop.
TOT'd back to stock firmware, 4.2.2. Managed to root device, and place custom recovery on it after multiple apps because I don't understand what the f*** "Loki" Is, or anything. So I attempted to flash 4.4.2 ROM, failed. Cool. Attempted to flash resurrection remix again, got aboot error, and loki-ifying failure of some stuff. Rebooted device, bootloop. Cool. So, how do I place lollipop on the LS980 4.2.2?
@edit, got LiquidSmooth 4.4.4 ROM on there from 4.2.2. Had audio error, flashed newer nightly of LiquidSmooth, got bootloop. Flashed KK Baseband from Cloudy's thingy for the LS980, ran CloudyG2 LP Rom, installed via aroma, now I'm stuck in fastboot. gg.
Are you sure you're flashing the right versions? i.e. D801 for T-Mobile, etc

Yeah, it was stated on by the pages of which, LS980 (Sprint), VS980(Ver) 802, int.. Etc.
Now I'm having to attempt to modify tot files to change model versions because my phone
Appears to be model LG-F320S in Download mode, but it's not. I flashed CloudyG2 3.0, and his LS980 KK Baseband
And that's what occured me to get stuck in fastboot mode. Now I've been reflashing stock firmware img's and I can't
Get back into fastboot mode, so I'm stuck in Downloading Mode but as I modify the hex, and try to do the tot file, I
Continuously get wrong model number. It's kinda aggravating...
@edit, managed to get back to 4.2.2 stock firmware with this http://forum.xda-developers.com/sprint-g2/general/dll-to-bypass-lg-flash-tool-model-check-t2990665

please be more explicit. like yes am on KK rom already rooted and have twrp.?
if you are rooted and have twrp are in kitkat..
use the links i provided in the other messages i sent you before this.
enter recovery. button vilume down and power at same time, at LG logo release power, then press again. select on white screen yes twice this should take you to recovery. or download quick rreboot app.
1. flash bootstacks 5.02 KK-bumped for you variant i thikn you have d800 make sure its for your model.
2.dont reboot to system go to main menu/ reboot into recovery from recovery.
3. install the slimmed official rom for d800. it has root, and can take ota updates if AT&T sim is used.
4. go to playstore download autorec for lollipop for d800 install.
5. install thermal twrp 2.8.7.3 again. reboot to system, then you are done you have lollipop. rooted and thermal recovery...
if you want to flash a custom STOCK rom, not CM or ASOP this are different. if you want stock custom rom 5.0.2 just wipe all in recovery. copy rom you want to install while in twrp. then install and thats it you have custom stock rom if you want to.

thats something wrong with bootloader.
go back to stock again.
go into download mode and flash
KK 4.4.2 tot or kdz. the one you used.
then root/use autorec for KK
use the 5.0.2 Bootstack with KitKat (Bump) bootloader: https://github.com/lg-devs/bootstack...ump-signed.zip
once you flash that reboot into recoveryy from recovery.once you reboot phone and takes you to recovery flash official slimmed LP rom. it should work.. something you flashed or didt follow steps.

Always get bricked after installing lollipop

Hello, today I decided to install Google Edition 1.4 rom, just after flashing I bricked my G2, and my PC detected a lot of partitions. I fixed that, flashed stock KDZ with LG Flash Tool, started again. And its the same result. Then after installing stock rom, I tried to install another Lollipop rom (Cloudy G2 3.3) and again PC detected only a lot of partitions.
Sorry for pure English.

[Help] D802 4.4.2->TWRP 3.0.2->CM13->BRICK!

Prerequisites: D802, 32 GB, Stock 4.4.2. I believe "Int" version (original motherboard was replaced)
I tried to upgrade stock 4.4.2 with CM13 and failed with the brick result (LG logo for a couple of seconds and the black screen then).
Now the recovery mode is available (TWRP 3.0.2 bump blastagator) but there is no android image loaded except CM 13.0 snapshot 20160418 which causes the brick state.
The questions are following:
What was wrong?
What proper android image can be used to unbrick?
How to load image on the phone?
Since I found Mount->USB-OTG checkbox in the TWRP, then I hope the OTG cable can be used to load image from USB flash drive. Unfortunately I can check it now.
Will be appreciate for the help.
KK bootloader, that's the reason. If you want to have stock bootstack you need to update to 5.0.2 stock, root and then flash TWRP and CM13. Everything'll work fine.

Thanks edi.
Do I need to replace TWRP bootloader with another one (I guess stock) and then update to 5.0.2 or I can start updating 5.0.2 with TWRP?
If you want to stay with stock bootstack:
You need to flash 5.0.2 KDZ file with download mode.
If you want to do it fast:
You need to flash hybrid bootstack.
Thanks a lot.
Fixed.
