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.

Hello,
I have LG G2 (d802 polish version) with 4.2 rooted stock rom, Installed pac rom two days ago and then (stupidly) changed build.prop ro.sf.lcd_density value from 480 to 240 and since then phone is bricked It's either booting forever (LG logo) or booting all the time to recovery mode( I have installed CWM recovery, and later Philz CWM). Now the good side is:
- I can get to download mode and connect to LG Flashtool. .When flashing the tot file BIN_LGD802AT-00-V10b-EUR-XX-SEP-07-2013-16G from XDA Storagecow.eu site, I can connec the phone via USb, change the port to 41 and it starts flashing. HOWEVER, when flashing the stock rom, LG flashtool skips all the partition and flashes it in seconds, then stops at 84 percent, tries to get factory reset,waits for it120 sec and then I have the error DOWNLOAD FAILS. What can be the problem here? Earlier I flashed the same bin file without any problems, and it didn't skipped through partitions , and everything went fine. WTF? Seriously maybe someone knows because I am desperate here. Already trying 2 days to figure it out. Haven't tried the KDZ method yet, because I have Windows 8,1 , and I am having permission errros while trying to flash. I will atttach a screenshot of LG flashtool skipping all the partitions whil flashing soon.
Please HELP!
clarification
In any case I am just asking why Lg Flash Tool is skipping all the partitions and flashin properly and then stopping at 84 and not restarting ? How can I flash back to stock? Any advice appreciated. thanks.
anyone can help?

Did you try to let LG Mobile Support Tool download and flash matching ROM file automatically? That worked for me when I was stuck in LG logo boot loop. In order to make Support Tool reflash ROM select menu Extra Featrues and then Reset Upgrade Error (or something like that - having tool in german here ) Of course phone must be in download mode and connected to PC.
Hope this helps
After kdz/tot flashing you might have to reset the phone.
either:
Hold volume down + power, wait for lg logo, release keys and hold them again (then proceed to factory reset)
OR
Hold volume down + power, wait for lg logo, release keys and hold volume up + volum down (then proceed to factory reset)
Did you solve this?
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?
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!
Update,
I fixed this problem by using LGUP. My phone was refurbished (ls980) so that's why twrp didn't booted,
Hello,
I have a LG G2 d802 32gb variant. I bought it a week ago. I was running andoid kitkat OS (HK D80220C). It wasn't rooted. I tried to get official updates from about phone section but "no updates". So i decided to manually flash updates from a rooted recovery as i did in my LG G3.
First of all I rooted it by "IOroot". Then tried to install custom recovery by "autorec d802". Everything went good and autorec was also successful. I asked me to reboot into recovery, I pressed yes and then it took me to "fastboot mode". I tried to reboot into OS by pressing power button (As battery is non-removable). Everytime it rebooted back into that fastboot mode. This once happened with me on LG G3. So i tried to flash "laf" and "recovery" image and downloaded from here
http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware
I flashed them by CMD fastboot method. Now it stuck at "LG Logo" and download mode was also started. So i decided to install a stock rom by KDZ or Tot method. First i tried KDZ method. I downloaded stock rom "Hong Kong D80220C_00.kdz" which it was previously running. Also installed all drivers, downloaded flashtools2014 and connected phone while in download mode.
I started KDZ method as told here
http://forum.xda-developers.com/showthread.php?t=2432476
But everytime it shows internal error on "2 or 3 percent". It didn't worked for me. So i decided to do tot mothod.
Download tot file, dll file, LGFlashtool, drivers etc.
Followed whole process which was also described in above post. But when flashtool reached at 94 percent and mobile was being rebooted it showed error
"Fboot check"
"Fboot Check"
"Can't reboot completely"
I tried to turn of phone at this condition by waiting and then doing a factory reset by keys combination but it keeps resetting and rebooting. I searched whole internet but can't find a solution. Can anyone please help me. Because i bought this cellphone a week ago for my friend and i would not be able to face him after showing a sick phone. Please someone help .
Only download mode of phone is working, It also keeps led light on while stuck at logo.
