This is almost embarrassing to post, but I need some help...
I have the T-Mobile G2, btw, which was rooted and with TWRP 2.6.3.3
So I was installing an AOSP ROM, and like a dumbass, instead of installing gapps like I meant to do, I accidentally flashed Smikey's KitKat ROM on top of Cyanfox. I realized it too late to stop it, and once the flash finished, I did a wipe of everything but internal storage and tried to restore a backup of CloudyStock. When I rebooted it goes to the LG screen with a secure boot error, and then a black screen where you can still see the backlight if you tilt the phone.
I tried using the LG Mobile Support tool to go back to stock, (It will go into download mode), but I can't get it to push any of the three stock images to the phone.
Holding down and power to do a hardware reset doesn't work either.
Help!!!
I picked up a cheap Tmobile prepaid to use until I get this figured out, but I want my G2 back! Does anyone have any advice at all, or did I brick my phone beyond repair?
I forgot to mention, I'm not sure if it's the phone or the drivers aren't properly installed on my computer, but LG Mobile support tool is reading my phone as a V500...

Anyone know if this method for unbricking the Optimus G will work?
Hi guys!
I just registered now but I am not new to this site at all.
Well, I have been using an LG G2 D802 (currently D80230B 5.0.2) for about one and a half years now, and I thought about proceeding further than rooting. I installed TWRP and flashed a volume boost mod with it succesfully.
The problem occured when I tried to flash a custom kernel in the hope of smoother system, features and customizability. I will write down in steps what I did:
1. I downloaded the kernel and put it on the storage of the phone.
2. I booted into TWRP and flashed the zip
3. I Wiped dalvik (or art? idk) / dalvik cache
4. Tried to reboot, I have only seen the lg logo appearing from time to time, but it's stuttering and sometimes the logo has green pixels around the screen. I can get it into download mode, but I had no result with flash tool, the software either stopped responding when I started the update without reading the phone, or it said after a minute of waiting to read the phone that port not found (USB or something).
Any ideas I can unbrick my G2 with, I really don't want to have it gone, I can't afford a new phone yet.
P.S: I have sent it to the service once in the past, so I guess my warranty is void by now.
EDIT: I got it working, the problem was that I didn't set the folder containing the kdz file at 'Work Directory'.
Hey guys. About a week or three ago I saw nightlies started rolling out for the D802, and decided to try the third nightly that has been released. While flashing itself went fine, I'm having trouble with getting the ROM to boot. After the LG logo the phone enters a blank screen, and won't do anything at all. I can barely notice that the backlight stays on, and I noticed that during this bootloop or whatever this is, Windows Explorer spams over and over I need to format the disk before I can use it when the phone's plugged in. I've read from someone that I should flash the ROM and google apps simultaneously, thus I've added them to a flashing queue and wiped the Davik cache after the flashing.
At first I thought it might've been my recovery being out of date, since I was running TWRP v2.6.x.x before, so I flashed the most recent version I could find which was v.2.8.3.73.
Doing this however made no difference whatsoever, so I gave up at this point and decided to wait for a week or two for the developer to fix a potential issue on the ROMs end.
Now it's fast forward to two weeks later where I'm typing this post after trying to flash the most recent version of cm13 which was available for my phone (the D802).
The problem is I'm starting to run out of ideas to do, so I'm hoping somebody can hold my hand regarding this issue. I really like to try Marshmallow and it's really irritating it doesn't work.
Thanks in advance guys!
i yhink you need to install boostacks when you install boostacks for your varian. dont reboot into system, just go back to main menu. then reboot into recovery from recovery. then copy the rom. flash and gapps ...
i also ecoment blastagator twrp to prevent ecreen dmage

Thank you!
I was having the same trouble with lineage OS 14.1 on my D802.
I always got a black screen after the logo of LG appeared.
luckily I could get to TWRP and push the alternative bootstack via "adb push (filelocation) /sdcard/"
Thanks a lot!

Hi everyone
Ill try my best to explain my problem
To be simple, i started with a 4.4.2 version on my phone. I was tired using a phone no longer up to date so i decided to root it.
Sunday night I decidec to install the **crDroid**v2.0 CFW
I install TWRP following the tutos and i installed crDroid and gapps just after.
After the reboot, the phone doesnt boot at all. Only the logo appears for a very brief moment and vanish and the screen stay black but ON.
I do not panick and use LGMobile Support Tool to get my phone working again and it also helped me to find out that Lollipop version exists
This update wasnt available using update tool on the phone directly
So i restarted from a 5.0.2 version.
Tried to root it so many times, with so many differents methodes but nothings working
So i reflashed a kdz file with lash tool in order to downgrade to KitKat 4.4.2.
I root the G2 again (easy) and i try to install Lineage this time
Just like the beginning, the phone doesnt boot anymore
Is there any necessary step i am missing in order to make it work or my phone does have a real problem ?
Because im kinda annoyed i checked like 4 differents websites including this one, and the result remains the same
Thanks to everyone able to help me, even a bit
Sorry for the bad english, this is not my primary language
Good evening
Without fail every time after the lg logo disappears after flashing a custom rom made for the h918 lg v20 I get a flashing black screen. I'm doing a factory reset/wiping davlik cache/ cache/ and data 3 times each time I flash the custom rom and sometimes I even go as far as wiping the internal memory completely even after a factory reset but no matter what I try without fail I always get the flashing black screen right after the lg logo disappears. I even tried upgrading twrp from 3.0.2.0 to 3.1.1.0 and I even tried flashing the no-verity-opt-encryption 5.1 and 6.0 but nothing I've tried seems to fix it so I'm asking for help now since I've exhausted my knowledge on what could fix it. What can I do to fix that issue so I can finally start using custom roms again? Any help would be most appreciated thanks in advance.
P.S. The only rom I could get to flash successfully was the stock twrp flashable t-mobile rom on one of the threads in the rom section of the lg v20 forum so for now until I can fix that issue I'm currently running that so I have a phone I can still use.

did you ever find a solution? I'm having the exact same issue and am pulling my hair out trying to get something to work
If the version number of twrp your using is in fact 3.1.xx then that could be your problem all the new roms im almost positive need the newest twrp from pheonix i think it 3.2.3.4 its in the deveopment section...ive heard alot of problems on this device with older interations of twrp. I would start there

Official lineage 14.1 only works with pre10p h918, some firmware blobs need changed.
I just built an unofficial for my own use a few days ago that should work, but I havnt gotten around to testing it yet.
lineage-14.1-20180721-UNOFFICIAL-h918.zip
lineage-14.1-20180721-UNOFFICIAL-h918.zip.md5
When lineage 15.1 becomes official the h918 builds will be aimed at post10p. x86cpu is currently doing unofficial builds for both.
