[Q] LG G2 booting loop (soft brick?)

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?

[BRICK] D802 fota partition fail. TOT doesn't work

Guys i need your help, I screwed my phone BADLY. I have D802 from Hong Kong

Phone restarts until LG logo and the diode is blinking colors.
There is only download mode available.

3. i flashed laf.img to restore download mode, it worked
4. i flashed aboot, tz, rpm, it allowed me to boot into system but screwed touchscreen

First double check that you can enter recovery. Hold the power button until the phone completely shuts down. Wait 5 seconds. Then hold power + volume down until it vibrates and LG logo shows up. Release both buttons. Then press them again quickly and hold them. You will enter recovery. Or the phone my offer to do a factory reset which btw won't happen since it will go to recovery by pressing the power button 2 more times. If you have TWRP then you are good. Install ADB on your PC and the LG drivers. When you have ADB, Download (check everything) related to JB and KK. Reboot the PC. Connect your phone with the cable. The PC will not recognize the phone. You have to use a little trick in the device manager first:
Press the windows key + pause/break and click on device manager. Right click on the faulty device with the yellow exclamation mark and hit properties then update driver. Click on the second option then from the list search for ADB or ADB device or something along those lines. Select the LG driver and hit OK. Unplug the phone. The phone must be in recovery still. Inside recovery hit advanced and look for ADB sideload. Check both checkboxes on what to wipe. If you don't already have a rom you want to flash, then use this one. It is a very stable and fast one and I only recommend it because I had the same issue as you and it worked for me. Download that rom and rename the zip file to rom.zip and copy it to the location where your adb.exe file is. You will also need the KK baseband modem otherwise auto rotation won't work. Search for it on the D802 dev thread. Now on your PC, open a command prompt inside the directory you copied the rom.zip (shift + right click) and hit "open command prompt here". Type in:
adb devices (this will ensure that your connection with the phone is alive. If you see some weird string then it works. That is the name of the phone btw)
adb sideload rom.zip

Installation will now begin. You are saved.
Of course all the above only applies if you have acces to recovery. But I wonder how could you screw that one up. It's literally a simple apk installation and a 1 button solves everything app. If you don't have recovery you can still try to save your phone with download mode. Here is a link that maybe helps but I havent tested it
And one last thing: Don't use Flashtool.

thanks man. But unfortunately no recovery. The phone ONLY goes to download mode.
I will try to flash .kdz because tot method didn't work. If .kdz fails then i don;t know.... expensive paper holder

D802 bricked after Lollipop update

Hello, today i tried to flash from recovery this lollipop zip: http://forum.xda-developers.com/lg-g2/development-d802/rom-stock-30d-flashable-zip-t3070383 and flashed immediately TWRP also.
Now when i boot up the device I get a critical demigod error screen from which I can enter Download mode.
So i tried to install v30a .kdzwith flashtool but the installation fails...
Any suggestions? D:
I can only get to download mode, the phone is correctly recognized from the pc and LG Mobile Support Tools sees the device but with SW OPTIMUSG3 1.4.1 (the rom i had when I flashed Lollipop)!

As said above, you should try .tot method; I was like you, .kdz didn"t work, but .tot method works perfectly. You'll be on 4.2.2, 'cause .tot method only support 4.2.2 version of android on D802, but you can upgrade after with .zip rom or re-try .kdz method.
Check second part of this tutorial : http://forum.xda-developers.com/showthread.php?t=2432476 ( "2015 (updated with pictures) TOT method" ).
Yeah, final thing: if, after .tot method you're stuck in bootloop, factory reset your phone (power off, then volum down + power key, wait for LG logo, release buttons, then volum down + power key again, and your phone should work like a charm). Let us know if it work!

do tot methot and it wil work follow this instructions get the tot files and the right dll i copy paste from a guy that had optimus and worked like this on him
"My problem was the infamous 2% bug with the KDZ. I think reason for this is the wrong device ID set in the 'build.prop' by the G3 rom for the G2. The flash tool expects a G2 but sees a G3.
I did not find a workaround for this BUT there is one for the TOT method. You will need:
- LGUnitedMobileDriver_S51MAN312AP22_ML_WHQL_Ver_3.1 2.3.exe (version does not matter)
- Setup_LGFlashTool_1.8.1.1023.exe - for flashing of a TOT
- LGUP_8974.dll - this is needed for the flash tool to accept all TOTs
- the right TOT for your device
Please google these, I just checked and found them all. You can also find instructions for them.
Install drivers and LGFlashTool then start it.
Start smartphone in download mode by holding the volume up key while plugging USB in PC. Phone must be off.
Wait for the device recognition then change COM port of the new device in Windows device manager to something between 41-56 so that the flash tool can find the phone. In the model config window of the flash tool select the 'manual mode' then enter the path to the downloaded LGUP_8974.dll in 'DLL' and the path to your TOT file in 'S/W'. Set 'Action mode' to 'BOARD DL' then press 'OK'.
Your phone should be shown on selected COM port. Now you can press Start (the arrow).

As you said the problem was that flashtool didn't recognise the G2 (probably it saw it as G3) so it keeps stopping at 2%.

ls980 lg G2 , Stock recovery , broken download mode, no rom

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.

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.

Need help on lgv20 h990ds to unbrick

I tried to root with dirty Santa steps
But unfortunately
At step16 my cell went to fastboot mode
After that i cant restart in normal mode and download mode
If i do multicolor display is coming
But system recognize the download mode
So I tried to boot stock rom with
Lg flash tool
But it says
Firmware mismatch
Like us996->h990ds
And stop installing in10 persistent
Even lgup detect my download mode
But model unknown error
So pls some help me in it
I checked the file.bat file santa
In 3 batch file it was
There was twp file mention in us996
Instead of
H990ds
So I think the problem starts there
Any way to re flash through
Fast boot
If any one can explain
Say it in step by step pls
Thanks in advance

Some one help guys

To get to a working rooted phone from where you are, enter fastboot mode (hold volume up while connecting to PC iirc), then flash the h990 version of my twrp, (fastboot flash recovery C:\path/to/TWRP/), pull the battery after running fastboot flash twice, then enter recovery by while holding volume down, press power until the screen turns on, then tap power repeatedly until it asks to factory reset, say yes twice, then flash a new kernel and magisk/supersu. Neocore is a popular h990 kernel.
To revert back to full stock, replace your LG up files in Program Files with the modded version from this thread, and use the partition DL mode it adds (select all partitions from your kdz file) to go around the model restrictions

Please help me.
Thank you..

Hi I ran into the same issue, but I managed to force flash the firmware by choosing "Erase Chip" option (while choosing the kdz file) in the LGUP tool. Then somewhere in the middle you have to click the pink progress bar to confirm a warning. Hope it's not too late buddy! I registered the xda account just to post this haha. The only issue is that the two IMEIs show up as 0 in the system, but the sim card (data and phone call)works just fine.
