[Q] LG G2 [Hard Bricked] - G2 Q&A, Help & Troubleshooting

I had a V30a lollipop on lg g2 (D802). Last night I rooted my phone, installed autorec and then installed TWRP with it. Then I openned TWRP and wiped my data and flashed resurrection remix Rom. I rebooted my phone and it got stuck at lg logo. Now it connects to the computer as LGE Android MTP. There is:
No download mode
No recovery
I can see the device as MTP media and all the files present in my phone but I can't do anything else. The screen is black.
I found a solution online that involves capacitor trick and then installing partitions but the problem is that my version was v30a and i cant find any partitions regarding 30a. All the files that I could find belong to 10a or 10b.
Is there any way I can still bring my phone back to life? Thanx.

go to download Mode and Start the LG flash tool and flash the kdz, i hope this will fix it
also you can use the LG tool and use (on German Upgrade Fehler wiederherstellen)

Did you try Tot method? What happens when you plug your phone to pc? Does adb recognize your device?

How can i try tot method without going to download mode ? as i said phone only have stock recovery , Yes there is an option in stock recovery "Apply update from ADB" by selecting that i can run adb sideload commands. And i can flash any zip rom from that option . I tried several rom's using this option but installation aborted in middle .
Does device manager in Windows recognize your device? In Tot method you do port settings to flash kdz. Also you can give it a try for LG pc suite.

Bricked D801 - TOT & KDZ recoveries both failing?

I've got a T-Mobile D801 and tried flashing to the stock lollipop rom D80130b_00 using TWRP and the instructions on this page, but the flash must have failed. I did a full factory reset back to stock 4.4.3 prior to attempting this flash and I'm not sure what (if anything) I did wrong for the flash to fail. I can boot in factory reset mode and select clear everything, but then I just see the android guy with gears turning for 2 seconds and the phone reboots again.
Now I'm in a bootloop where I get an "error: Boot certification verify" above the T-Mobile startup logo followed by a "Demigod Crash Handler: Critical Error!" screen that provides options for rebooting (volume down) or putting the phone into download mode (volume up). After using the volume up the screen displays "Volume Up is pressed: Jump to Dload mode" and after connecting via USB appears in device manager as "LGE AndroidNet USB Serial Port (COM41)". I can't (1) boot directly into download mode or (2) get back into TWRP.
I've tried both the KDZ and TOT methods listed in this thread and neither are working. The LG Flash Tool 2014 / KDZ option starts the LG Mobile Support Tool, but it fails every time once "S/W Upgrade is in progress" reaches 4% with a generic "Upgrade stopped due to an error" message.
The TOT method fails every time with a "Model Information Check FAIL!" message. The full text is - "PID: NULL, IMEI: NULL, Model: , DLL:801, BIN: BIN_LGD801AT-01-V10c-310-260-AUG-13-2013+0.tot , SWV: , SWOV: , Model Information Check FAIL! , 00000000"
I've also tried using srktool to repair fastboot, but it gets stuck at "waiting for device".
What do I try next?
Finally got back into 4.2.2 using tot method. LG Mobile Support Tool doesn't think updates are available though??

Yes, I *think* what happened was that my 30b bootstack was flashed successfully via twrp, but then the actual kdz flash of D80130b_00 failed. I had a lot of trouble at this point - needed to fix qhsusb_bulk problems first, then use the more aggressive TOT flash method to reset to stock 4.2.2.
Finally the LG Mobile Tool was still reading it as having D80130b_00 / lollipop after going back to 4.2.2 via TOT (?). Last step was to do a full restore from the LG Mobile Support Tool (options -> upgrade recovery) and it actually downloaded / flashed D80130b_00 so everything is working well now :good:
If it helps anyone I used the LG backup tool to restore apps / media and have to say that for a stock solution it's pretty solid.
qhsusb_bulk?

you said your g2 was detected as a lge androidnet in device manager but not as a qhsusb_bulk...then what problems have you fixed about qhususb_bulk? and what is the more aggressive tot method different from this threadhttp://forum.xda-developers.com/showthread.php?t=2432476
Were you able to find a solution? I'm in the same situation. Please help!

LG G2 screen berzerk after flashing Rom

Hello everybody, I bought a G2 a while ago, the seller told me it's a D-802 (which the backplate tells also), i wanted to upgrade it to Lolipop using LG Support Mobile Tool, since the tool flash on it's own and I have limited knowledge of Android Flashing, I let LG Support Mobile Tool do the work, when it finished the screen went berzerk (not calibrated), I opend the backplate and it is written D-800. My friend succeded to enable USB Debugging, Root it, and install TWRP custom recovery, since i tghought that it is a problem with the Kernel, I installed Dormimanx LP kernel for D-800. now i'm stuck in "[870] Fastboot Mode Started". please heellpp :crying:
If your model is D802, you need install D802 rom and kernel. Go download mode then install stock rom or go twrp and install any rom you want via adb/otg...
TWRP works and download mode works but i can't install a D-800 rom with LG Flash tool V1.8 because it says that my model is a D-802 "Device model is different. Check phone or DLL"

Bricked LG G2, download mode goes on, but not working

Hello
I'm new here, I've been modding my lg a few times, always when bricked, kdz or tot files were saving me.
But now I've got real problem.
I was changing ROM from Cyanogen 13 to Cloudy 3.3. I thought I just need to flash rom via recovery (2.8.7.3 bump blastagator). Flashed fine, without any troubles, but when it came to reboot, phone just got stuck on LGs logo.
I knew i f*ed up.
Recovery isn't working, but Download Mode is turning on normally, at least it seems to.
So i tried to flash KDZ, but LG Flash Tool immedently shuts down giving "lg user...." error (don't remember what exacly it was saying).
Then i tried via tot files. But after installing drivers from tutorials, device isn't showed as "LGE AndroidNet USB Serial Port", but as few positions like MTP device or usb serial port(but not in Com ports) and all are marked as devices without drivers. Flash tool for tot also didn't worked here, because it did't found device.
What can i do now? Please help me.
[Edit]
So now, using different drivers somehow Jelly Bean installed by tot method (device didn't appeared as tutorial said, but it worked) phone is booting normally, but i can't again install lollipop with kdz files.
I was trying 3 different drivers, every giving instant error of flash tool.
What can I do now?
[EDIT2] LGUSERCSTool.exe is crashing. How can I install lollipop now?
Are there tot files for lollipop?

H910 LG Logo loop | tried many KDZs | factory reset not helping

Hi,
my H910 is not starting Android anymore.
I flashed many KDZ Files (different versions) with LGUP:
First in the mode "partition DL" (selected all partitions), after that I tried it often with "Upgrade" option.
Everything seems to be succesful, but LG V20 is in boot loop at the LG logo.
Sometimes I can see after LG Logo a circle with "erasing" for some miliseconds.
Tried recovery factory reset, circle spins some seconds then reboot and same loop.
Download Mode always works.
Factory reset dialog (recovery) works, but erase progress seems not to work.
I don't know what I should try now anymore.
EDIT:
Downloaded newest LG Universal Mobile Drivers from LG Site and now everything works
For the sake of leaving a record what helped you out of your problem, could you clarify?
You downloaded the latest LG Universal Mobile Drivers from LG site and installed them to your PC, replacing the drivers that seemed to work (the device was visible, LGUP did not complain).
Then you used the LGUP again to load something and that fixed the bootloop. What was that thing you loaded after updating the drivers?

Hi,
yes new drivers from LG site was my solution.
It was correct visible on LGUP before too.
Now I flashed same as before firmware 10f, than dirtysanta root and than recovery. As written in that "How to root" threads.
Seems like old LG drivers hat maybe some problems with Win 10 so that not everything was written correctly.
