[Q] LG G2 booting loop (soft brick?) - G2 Q&A, Help & Troubleshooting

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?

[Q] Soft-brick? ADB sees the phone.

Hello guys, I have a problem with this phone.
First I flashed the euro+fastboot kdz... The phone booted and worked awesome but It wasn't showing recovery or LG logo.
Somewhere on this forum I read that you had to flash v10c and then v20B to fix this.
I did so, v10c failed, but v20B flashed correctly, but it didn't boot up.
I'm still stuck here, the phone is completely dark, but when I connect it to the pc I can see it with ADB, It just doesn't go into fastboot mode (because of v20B I guess). But flashing the euro kdz won't work anymore, and I'm stuck in ADB without fastboot.
Hope you guys can help me,
Juxter.

Thumbs up solution to get logo
solution from 4PDA
flash first french firmware _hxxp://csmg.lgmobile.com:9002/swdata/WEBSW/GT540/ANEUBK/V20a_00/V20A_00.kdz
(you must make kdz flasher fullscreen and change right option to CS_EMERGENCY)
dont boot android , remove accu reinsert them and press vol - and plug usb cable into port on mainboard - you must get in download mode )
flash firmware with fastboot (i use CIS _hxxp://narod.ru/disk/26675062000/V20B_00.kdz.html)
boot android and flash this firmware _hxxp://narod.ru/disk/25473801000/out.kdz.html
after this you must see all logo ( LG , Motion LG , Android )
after this flash firmware you like (custom fastboot e t с)
maybe some point is not needed but this tutorial work 100% and tested by myself

So after 4 5 6 or maybe 10 times, it will finally become working, that's what you're saying?
This is really odd, something's wrong with these phones lol
Okay, i'll load myself with a ton of patience and repeat the steps as per the instructions. This is *exactly* how i am doing it, with all the details:
1) Using the French v20A ROM - http://csmg.lgmobile.com:9002/swdata/WEBSW/GT540/ANEUBK/V20a_00/V20A_00.kdz and this Russian one - http://narod.ru/disk/25473801000/out.kdz.html
2) Take out the battery, SIM card and SD card
3) While holding the Vol - button, plug USB into phone so that the phone goes into Download Mode
4) Run the KDZ Updater, put it into CS_Emergency mode
5) Select the French V20A rom and flash it
6) When it's finished (immediately after the DOWNLOAD MODE letters vanish), i pull out the USB plug from the PC, so that the phone doesn't boot.
7) Again hold Vol - and reinsert USB to put the phone back in Download Mode
8) In KDZ Updater (still in CS_Emergency mode) select out.kdz and flash it
9) Let the phone boot into Android
At this point i STILL don't have a boot animation, should i keep doing this until i see one appear?
When it (if) finally appears, i just flash my own ROM, do a factory reset and it should stay that way, correct?
I guess my impossibility to access recovery mode also has something to do with this...

Note: For above step: 1) Using the French v20A ROM
-- as long as you have the ROM of v20 with fastboot option, it doesn't really matter.

Thanks for the reply, I actually fixed it following this:
hxxp://modaco.com/topic/329863-how-to-raise-gt540-from-the-dead/
Once I got fastboot with that cwm.kdz I reflashed a fastboot rom, and from that one I could use the KDZ updater again, following the French kdz procedure...
The phone now is fully working recovery and bootanimations again

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.

[Help] LG G2 bootloop, Only open in download mode, No recovery

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.
