Hi so my friend gave me his LG Leon to flash CM 12 because he didn't use it anymore. For my surprise when i turned on the phone it boots automatically in flash mode showing "910K" in the little box. I try to flash a kdz but nothing works, when the phones restarts boots in flash mode again.
I installed TWRP but always is showing that is not detecting the OS.
Why can I do?
Is a corruption of the partitions?
help
Try to flash a official rom using LGMobile Support tool. Connect the phone, open the program and Select "Option -> Upgrade recovery".
From what I can gather, the recovery was either replaced with an incorrect version or was corrupted.

Hey,
I've tried to flash my lg g2 d802 with CM 11 with TWRP recovery
after 5 minutes is says : "fail"
I selected reboot system the phone stuck on the lg logo and the phone won't boot
then I've wipe everything
tried to boot the phone the phone won't boot
then i read a thread on XDA : http://forum.xda-developers.com/showthread.php?t=2451696
via "terminal command" method and the phone won't boot
then I booted the phone into download mode and downloaded kdz file then i tried to use the flash-tool and I have the "lg drivers" and also "lg-mobile support tool"
then the flash-tool is not responding :/
so what i can do ?
and should I wait for kitkat official update or flash rom ?
and if I want to flash rom which one is better for lg g2 d802 ?
Well did you make a backup b4 you tried flashing the rom to restore it if anything were 2 go wrong ? Its most likely it flashed partially but it wiped your original rom thats why u couldnt boot . if you can still boot into recovery mode try flashing a diffrent rom if you have any downloaded
Hellfire and liquidsmooth are best 4.4 roms...
Try installing these roms..
I have a new and unique problem with my set Ls980 (LG G2). I dig down all xda and other forums from last week. But no use till now. So i need some good help from experts . Ok here is the situation . I have Lg g2 ls980 (sprint) i rooted it to flash some LP custom rom in it. i installed RECURRECTION REMIX LOLLIPOP ROM in it successfully along with it's gapps. After reboot i got my phone in boot loop. now the current situation is that
1- I have nothing on my phone everything wiped out. no rom backup or anything else on my phone memory.
2- I have stock recovery (pictures attached).
3- I have broken download mode. ( so i can't attach my phone to lg flash tool) picture attached.
4- I am stuck on boot loop with cm11 M5 ( last rom installed using adb sideload option from stock rom)
5- No fastboot mode.
Please guide me to recover my soft bricked phone.
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.
My LG G2 d802 is stuck in the download mode and has no recovery. It happened when i flashed Miui 6 by gtbluesky after full wipe of data and system. Previously it was on cloudy 3.2 . After flashing the miui it wont boot and is in a bootloop on mi bootscreen. I tried but cannot boot into recovery seems like it doesnt have a recovery.
However, I can boot into download mode but it is not recognised in ADB nor Lg flash tool. I tried flashing kdz with the lg flash tool but it wont detect the device. I tried installing various drivers to the pc and also tried two different pc with windows 7. However, adb wont detect the device.
Regarding the drivers, the windows installs all the drivers but fails to install the LGE Androidnet usb modem drivers. If i manually try to install it from the lg drivers, it would keep installing and returns an error of timeout period expired.
So, i am stuck in the download mode with a bricked device.
If Someone could help me with this problem, i'll be much obliged. Thanks
SOLVED
[SOLVED] I downloaded the .tot file for my phone and extracted .dll from one of the .kdz & flashed it using the lg flash tool . It flashed good and now my g2 is up and running. :good:
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??
same situation lg g2 d802

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!

Did you shut down your phone and enter it into it's download mode (when it's shut down, hold the VOL Up button and plug it in to your computer's USB port simultaneously)? The current version of LG Flash Tool 2014 has a option called "CSE Flash" which deletes the ROM you installed and the Internal Storage's data, and installs the stock ROM you are trying to install. All you do is make sure your phone is on Download Mode, have the KDZ selected, select CSE Flash, hit "Start" select "Different Country" (as it have Korea as it's default choice), select your language, wait for it to be done. I hope it worked for you, as it worked for me.
