Ok guys look, I bricked my LG g2, made it via tot method cuz nothing else was working (no recovery, secure boot fail) (no Rom, already wiped) (download mode with LG flashtool 2014 stuck always at 2% and sometimes crashes on read phone info) and also I'm encountering a cdc driver fail.
Whatever tot method worked, dunno how but did.
Now I'm on rooted 4.2.2 unknown carrier stock Rom.
What now? Can I freely flash? Do I need to upgrade the bootloader and then flash? How is that done?
I just want cloudystock but I'm really afraid of upgrading after all that fails and this brick. Can someone help me please?

As stated in title:
- Updated to stock V20X (no root), then tried to flash V10k rooted/CWM/bootunlock etc.
- Can't flash through KDZ updater whatever the mode (DIAG/EMERGENCY) because of a Wparam/Lparam error every time
followed various tutorials to the letter, even with a downgrade solution but still no dice.
I usually end up with the yellow emergency screen as a semi-brick (have to use LG phone recovery method)
Not sure if if there's something I'm missing here, I'm used to the optimus 2x which never fails when flashing KDZ files.
Any help would be much appreciated! Thanks

Resolved: flashed the downgrade file and ended up with LG logo bootloop, looked a bit further into the issue; had to do a hard reset (which led me to see that CWM had actually been installed) - wiped/reset through CWM and boot finally worked.
Hello guys! I bricked my device, so it doesnt boot right now. I was on Cloudy Flex 2.8, then I wanted to flash Cloudy G2 3.3 (G4 ROM), but my phone was bricked. I wanted to solve these problems with SRK Tool. I did this option there: Unbrick - qhsusb_bulk 9006 (No Recovery Mode,No Download Mode).
Now, I can enter download mode, but afraid of entering recovery cause I think custom recovery lost, that's why If I try to enter recovery device will be factory reset. PC doesn't see my G2 Device gets "Security error" when boot. So, I dont know what I must to do. Want to back to stock but If I used to flash stock roms with kdz or tot methods after I must do factory reset And I don't want to do it. How can I backup my datas right now? And can I rescue my device without flashing stock Rom? Thanks in advance! Regards!!!
OMG Noone can help me :crying: Please, help me friends!!! I cannot do anything right now
Hey!
I have a problem with my LG G2. After unbrick my phone and successfully instaled Cloudy G2 3.3 I can't get into Download Mode. I think i might broke it while I've been trying a few methods to unbrick my phone. But after all I went through I'd like to install stock rom by KDZ and stop being worry about my device. But first I need to fix download mode somehow. I was thinking about flashing laf.img by TWRP but I'm worried that it may break my phone and leave me with no download mode, no system and no recovery.
Any advice?
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!
Well, I searched for a solution for a long time but I couldn't find one.
I accidentally flashed CloudyG3 2.5 on my LG G2 Korean LG U+ Variant (F320L).
I got HS-USB Diagnostics 9006 on my device manager and I managed to recover it via this thread.
I couldn't use the tool right way cause they didn't have my variant, so I extracted images from F320L TOT and replaced those aboot.img, laf.img, etc.
I got into the download mode and launched LG FlashTool (the TOT FlashTool) and loaded up my TOT and DLL on the tool and attempted to flash.
BUT the error "CrossDL [F400] to [F320L]" was shown in the log.
I think this problem is caused by flashing G3 ROM on my G2, changing the model name in system partition.
I have no idea how to solve this problem.
I tried flashing all kinds of g2 dll, but failed.
I considered flashing the G3 firmware, change the information on the phone, and re-flash g2 firmware, but I think that's gonna make the problem more difficult...
I tried booting into recovery and flash g2 custom firmware, but no recovery mode.
I tried fastboot mode, but phone just says "Security Error" and won't let me get into fastboot mode.
What should I do?
Please ask me if you don't understand exact situation. Sorry for my bad english...
