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.
Hey Guy,
Im a Noob. I bricked my phone trying to install a KitKat Rom and a Custom Recovery, and now it wont boot past the LG Logo Screen. I've tried the .kdz method and the step that says "Select country and language" window that never pops up. The TOT method gives me an error stating my "device model is different."(View attachment for error and dll file). Ive search every possible forum looking for different methods on trying to flash the stock rom. I can only access Download Mode and Recovery Mode(ClockworkMod V.6.0.4.4), I've attempted to mount USB storage through recovery but thats not working either. Ive also tried doing a "Upgrade Recovery" through the LG Mobile Support Tool and it spends like 3 hours downloading the firmware but never installs.
KDZ Method.

I'm at a stump and need guidance. Please help. Thanks.
I have worked all day on this and am now totally out of ideas. My LG G2 is without an OS so I am left with Sideload or Push. I have tried Kitkat and Lollipop roms. I have tried android and LG us drivers. I have tried downgrading TWRP to 2.7.0.0 (I am on 2.8.6.1) by fastboot (that just says waiting for device).
Everytime I install ANY rom (either by sideload or adb push) it fails at about 70% with the error 'executing update binary'.
Can anyone get a rom back on my phone please??
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!
Hi,
I have problems to get root access on my LG G2 (D802). I have a refurbished Vodafone device, which runs with the Lollipop version (5.0.2). The phone boots into the OS and works fine (as you can say with 5.0.2), but I want switch to CM13.
Unfortunately I can't access the download mode: I got the "Boot certification verify" error, which results in a DemiGod Crash Handler. I know, I should flash the phone with a stock version. But: I can't downgrade this phone - I tried every LG flash tool version.
Either the LGMobile Tool Suite says I already have the latest Firmware (trying to install a older version -.-), the process just stops because the phone is missing a functional download mode or the whole process just stops at 4% within the "S/W Upgrade is in process"-task and ends with a error message ("Upgrade stopped due to an error").
When doing the command "adb reboot recovery", the phone restarts. Sadly I only see the droid laying with an exclamation mark. I once accomplished (still don't knowing how) to get the options and I tried to install the kk_root.zip with the command "adb sideload", but there is another issue/error message: "E:failed to verify whole-file signature / E:signature verifcation failed"
Is there any other way to get around this mess and to install CM13?
Thanks in advance,
dash
