[Q] G2 won't boot after failed custom ROM flash (LG-D800) - G2 Q&A, Help & Troubleshooting

So after trying to backup everything in recovery and flash PACMAN ROM for my phone, everything seemed fine, until it rebooted... When the LG logo appeared, suddenly weird horizontal lines started going across my screen and suddenly the edges of the phone started greying until the whole phone started going greyish-white, then powered off. I tried rebooting several times, and eventually it just wouldn't boot at all. If I hild the power button, it vibrates for a sec and nothing. When I plugged it into my PC, I can access it like a USB storage drive and my internal storage is still there, but I can figure out how to fix my phone. Did my screen die? Is there a way I can recover my phone from my PC via USB?

Back up your internal storage to your pc, more importantly the nandroid which is in the TWRP folder. Then follow this guide to get your phone back to stock.

I think that rom is kk u can find more info about that problem in liquidsmoth thread please tell me if fix it if not that mean how I know maybe u need to replace something in motherboard

Art is right. Follow the guide to get back to stock. If that doesn't work then it's a hardware problem.
Looks like I'm never trying the pacman rom on the g2...

Ok update. After following the steps in that guide posted, the firmware loaded and the AT&T boot screen popped up after reboot, though now LG Flash Tool is still doing it's thing and the screen's off with the phone still in USB and power light slowly blinking red, so I have no idea if it's fine or not.

Alright, it turns out it completed the installation and I just had to unplug it, it now works! I just want to know of which custom ROM to go with now.

Check the index in my signature, the roms are organised by android version and variant

Need help with possible brick

After several attempts trying to apply Lag Fix, my phone ended up doing endless boot loops and due to my ROMs being on the SD Card instead of Internal SD, I could not flash it and seem to not have access to somehow get the ROM file from External to Internal SD. I then tried to restore the Stock ROM through Odin and it failed miserably, with several stalls that eventually led to the screen shown below. This screen stays on when I press the power button and nothing else seems to work. Removing SIM and SD Cards also did nothing.

I got it past that by plugging in the USB cable and getting into download mode with Power/Vol+/-. However, I can not get anything to flash via ODIN once connected. ODIN does recognize the device on port 6 but once I select the stock files nothing appears to happen from there. ODIN just sits there. I went on a walk at the boardwalk to see if I just needed to give it more time but it was on the same screen. If I flash a kernal it sits at zImage, and if I flash a ROM it sits at cache.rfs

if you can get to download mode just keep trying to flash with odin. I think some mentioned loading the files before you plug in the usb cable.
I am in download but still no progress. I've tried a lot of times and it just sticks at cache.rfs. I think its a total brick. ODIN **** out on my when I was flashing JAC's kernal. Can't get anything since then....
Regards,
B
OMG I finally got it. I had to leave ODIN open after it stuck at file analysis. I then took out the battery of the phone and put it back into download mode. I click start in ODIN and thankfully... she's flashing back to stock 2.1. I had tried a million different ways... ODIN is not exceptionally stable. No bueno. I think I'm going to keep the stock Kernal cause this was scary... lol.

Need to turn on Moto X Pure *without* power button (not rooted)

Hello all,
I'm in a jam here and hoping one of you can help me out.
The power button on my Moto X Pure Edition, which is not rooted, has stopped working completely. The battery died overnight and, obviously, the phone powered off. Now I can't turn it back on. I'd like to get it turned on or at least get my personal data off of it. Does anyone have any ideas?
I have figured out how to get it into AP Fastboot Flash Mode by holding down the Volume Up & Volume Down buttons simultaneously while plugging it into a power source. But, I cannot select "START" (or anything else) from Fastboot because my power button doesn't work.
Hoping I can figure out how to do this without taking apart the phone, which will void my warranty and probably won't result in me being able to fix it anyway.
Thanks so much for your help!

Do you have fastboot installed on your computer? If you do then issue the following command : fastboot reboot
Your phone will now start up.
If you don't, install it. You will have to research how to do it for your system. I'm on Arch Linux, so won't know how to help you, but there will be a google guide.

Hilarious. After an hour of fumbling around I figured out the USB port I had the phone plugged into was bad. Plugged it into one on the other side of the computer, recognized, rebooted, good to go.

Hi!
i think your phone board was damage in process, happened to me on a Alcatel Idol... The same thing. I think the phone was already a bit laggi, no?
.
Phone was not worked properly,thats what my mother in law said.
Its sometimes show just white screen after unlock,or camera wont switch on.
And battery draining fast.I thought firmware upgrade will fix it but its brick now(
Update:I have fixed the phone with dc phoenix software-Installed new board firmware and then stock rom and its all ok now.

You can try to do a hard reset I hope does it but it could be hardware issue.
Sent from my SM-A730F using xda premium
The hard reset doesn't work because the phone reboots when I enter to the recovery mode.
Someone told me it may be because I let the phone go to 0%. Do you think it's possible? If that's right, what do you think I can do now?
Thank you

In that case leave it plugged in for a day and then retry reseting. You calibration could be out of whack.
If you are using the Leeco supplied usb C cable, replace it with a higher quality cable.

So here's the problem with doing this, I have no way of flashing Mr.Bump at the moment with the stupid tablet looping like it is. When I plug in the tablet I don't get the bepoop from my laptop telling me its plugged in and ready to go unless I press the power button and volume down. But then I get what the second picture showed, at that point then the pc does the bepoop sound but I still can't do anything with the tablet. So I guess my next question is how do I flash or use this with the state my tablets in? Thanks.

Can you not even boot into bootloader/fastboot or TWRP/recovery?
You should be able to boot to recovery by following the steps shown here -> https://www.hardreset.info/devices/lg/lg-lk430-g-pad-f-70/recovery-mode/
You could also try and boot into safe mode and try and use the magisk manager to uninstall magisk - howto here -> https://www.hardreset.info/devices/lg/lg-lk430-g-pad-f-70/safe-mode/
okay update, so if you look at the fsecond picture it says fastboot_init() I assume this means its initialised? I have no idea what any of the stuff below that means. when I do the recovery mode it shows the words recovery for like a second then gives me the black screen with white text that you see in picture 2. when I try the other method all the tablet does is bootloop with a new error code of 2250 I think. So I have know idea whats going on with this. I'll try uninstalling Magisk like you said but things are looking bleak I feel?

somebody else apparently had the same experience although on a different LG device -> https://forum.xda-developers.com/lg-spirit/help/help-fastboot-error-loading-keystore-t3430163
So it seems that fastboot commands may have been disabled which means you can't interact with the device in fastboot mode whatever you do.
If nothing else works, you could try and re-flash stock ROM if you can manage to get into download mode.
Best of luck!
