Brick other brand new LG G2 D802 32GB taken out from the box. Oryginal version of KDZ installed by factory: V20B. Upgrade to V20 G (45 Baltics). Phone connect to PC with download mode, CDMA, DIAG, CSE Flash. Phone Unrooted. After finish download the firmware into phone following symptoms: when touch the screen for example "english UK" the phone doing something different/elese-the phone select together other 2 buttons on the bottom (arrow button and 3 lines), phone is completely crazy, go to next step (from point of select the language) is impossible. Recovery Mode not available, Download Mode available.

I tried repair method with TOT & DLL file using LGFlashTool 1.8.1.1023 unfortunately this not help.

I think the reason is that phone should be rooted before upgrade (before use the FlashTool).

Anyone has any solutions,suggestions?
[G2 Android Development] DominikHolecek:
Always crashed on 4 % however it doesn't even start on the phone at all... I don't know what to do... It looks the same as on previous method - it was solved by flashing it on en version of Windows (It was the recommendation of LG, I don't know why but it doesn't work on our CZ version of Windows), do I have to do the same again (en Windows) or is there another option?
[G2 Android Development] vassagout:
does Flash Tool works on unrooted and locked bootloader devices?

regards.
[G2 Android Development] kt-Froggy:
Yes. As long as you can boot into the download mode, it will work.
[G2 Android Development] vassagout:
thanks. I already tried and I can enter to download mode, so I think following the guide in the OP I can flash D850 v20a final kdz from stock 4.2.2 using CSE Flash. Any advice?

Regards.
[G2 Android Development] vladmir:

Guyz i m on d802 model indian version.....is it safe to do cse flash choosing CDMA instead of 3GQCT and den what the procedure....???

Will this make me complete unrooted?

And if not den pliz xplain me procedure bcuz loads of links are on xda are there to unroot.
[G2 Android Development] kuppenhorst:
Procedure stays as in the op described. If you change some options than in my experience the worst case scenario would be that it either will get stuck in process or the process won't even start. Either way you can start over again. And yes no matter what flash mode you'll choose it will take away your root.

Having said that...your device may still show rooted when in flash mode. In my experience you would have to go to d80210a and than flash d80220 again to have that gone.

need help

i have LG G2 D802 32gb ... heres the details...

i tried to flash twrp recovery which lead me to fastboot with no recovery no download mode no adb connection just fastboot...

after two days of reading threads after threads i flashed "pgpt32g.img" "rpm.img" "sbl1.img" "sgpt32g.img" and "tz.img" with fastboot.. after that i finally saw my device booted normally.. but dont know why the touch went crazy... like theres something wrong with the screen... i thought i messed it up or its some software issue... so i downloaded D80220F_00.kdz and flashed it on my phone... once again i am stuck.. now on LG logo... after that i downloaded ""Europe OPEN D80220B_00"" "TMO-EE 32GB D80210B_00" and "UK Open 16GB D80210B_00" and flashed them one by one ... i am still at my LG logo phone doesnt go further....

now... i found these websites here on xda

http://lg-firmware-rom.com/

http://csmg.lgmobile.com:9002/csmg/b...heck2.jsp?esn=

and yeah i tried searching the firmware with entering my imei and both sites are giving me same kdz now...

my question is if i flash this file now will my device boot or i should just stop wasting my time on it? and what about the touch screen is there any way i can confirm is it software messed up or hardware?

thanks for reading so much for me hope u guys will reply soon
[G2 Android Development] kuppenhorst:
may be here you can find it

http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/

1st: for your screen issue you should take a look at this thread:

http://xdaforums.com/showthread.php?t=2769770

although i think it's driver/software related

2nd: i recommend you to go back to the last point where you could boot into download mode. then try repairing/updating your firmware with the lg support tool and the lg r&d flash tool. take a look at this thread

http://xdaforums.com/showthread.php?t=2498102

if that does not help repaet the steps that lead you to a booting device and try flashing an d80210a.kdz. after that, no matter if it got stuck try repairing again or try to flash with flashtool 2014 again. sometimes the proces get stuck. just try again.

you can download the kdz from here:

Don't think LG changed something. Just flashed with this method and everything went smooth. But there is another method available. Just Google offline flash method for LG g2.

Also you could try access your recovery and factory reset/ wipe all. After that try this method here again.

[G2 Android Development] kuppenhorst:
You are stuck in bootloop? Switch off the phone by holding the power button and then try to get to recovery. Doesn't matter if stock or custom. Perform factory reset. If you can access custom recovery wipe everything you can.

You can also try to repair the firmware with LG support tool.

[G2 Android Development] ksio89:
Thanks, OP, this tool is SO much easier and safer than the regular KDZ Updater (with offline fix). This works just fine with LG Optimus G (E975/977) as well, just select "DIAG" and then "CSE Flash" to flash stock ROM 100% clean. I don't even need to perform hard reset afterwards. No hassle with scripts, it just works :good:

Help, I used this method and now I am stuck on the LG logo screen. I went through the steps, it seemed to complete, then the Android with the spinning geometric stomach came on, and then the LG Logo screen with the LED pulsating green and froze there. I tried doing the process again but got stuck. Please help.

I can restart the phone with power+volume up. It shows the Android with the spinning geometric stomach for a few seconds and then goes to the LG logo and stays there.

If I try to run the process from the start again it shows a few lines printed on the phone ending with

fastboot: processing commands

and it says on the tool 'Upgrade stopped due to error'.

I am not able to get into recovery though I have never tried before.

I 've tried. I put the tablet in download mode I started Lg flash tool and I set CDMA DIAG 3300 , the processes you crashed at 4% . Then I had to reset the tablet with LGMobile Support Tool because it came out of the download mode mode.

My questions are two :

1. I have to change some settings for Lg flash tool ? (I have to pass by the V50020d V50020a)

2. To exit download mode as you do ?

Sorry for my english
[G2 Android Development] kuppenhorst:
when the proces gets stuck just try again. i got stuck lots of times and just played with the option available.

did you try emergency mode too?

are you sure you cannot get into recovery? retry the proces. doublecheck all steps in the op.

if nothing helps. try to repair your firmware with the official lg support tools to get a booting system in the first place. if you got it booting try factory reset and repaet the flashing proces.

---------- Post added at 08:36 AM ---------- Previous post was at 08:29 AM ----------

some things you can check/try:

repaet and double check all steps from the op(drivers etc.)

try entering recovery(google how to do that) and factory reset.

what happens when you connect the device to pc?

try playing with the option available in flash tool.

try to repair firmware with the official lg support tools or try offline methode in case its a bug of the flash tool or offline methode in case its a bug of the flash too.

[G2 Android Development] kuppenhorst:
Your main concern at this point should be to get a booting system again and then go from there...to twrp. Your problem point toward some problem with your devices' partitions so you gotta solve these issues first.

What happens when connecting your device to pc?

Can you enter adb/fastboot or download mode?

Something went terrible wrong and I need to flash a KDZ. I can't get this tool to work.

Some questions:

1. On the phone USB debugging was OFF when I got stuck on LG logo with only download mode left. Is this a problem?

2. When I connect to Win7 three devices were found but the device "CDC serial" later named "LGE AndroidNET USB Modem" couldn't find a driver after a LONG try. Is this driver needed?

Although not installed correctly, this "LGE AndroidNet USB Modem" shows in device manager without exclamation mark. I tried a manual update with the drivers under '/LG United Mobile driver' but without success: Error, Timeout

4. Are there any alternative drivers?

4. The flash tool always stops at 2% with error whereas the update process on phone does not start at all. Related to the modem driver problem?

5. Did someone have similar problems and knows a working alternative (offline/tot/?)?

D802, OptimusG3, TWRP 2.8.2.0, Dorimanx 9.2, KK modem, bumped

Stuck on LG logo. TWRP not accessible.

Drivers tried: LGUnitedMobileDriver_S51MAN312AP22_ML_WHQL_Ver_3.12.3 and 3.11.3

To buy a new phone is not an option. Any help would be highly appreciated. Thank you for reading.
[G2 Android Development] kuppenhorst:
You don't need usb debugging in dl mode.

Try deleting the android usb modem in device manager. If this doesn't help try deleting the one with exclamation mark. Check if something in the flashing proces changes.

There are no alternativ drivers.

You should be good with the drivers provided here.

Lots of poeple have similar problems. I had those too but could solve them. There's a whole variety of possible error sources and therefore lots of things thats could be done to get rid of the problems. You should start eliminating those possible error sources. For example close all processes and programs not vitally necessary for running your pc and the flash tool.

Are you using some kind of android emulator? Kill its proces.

Just try to flash after any change and look for any improvements. It will flash or it won't but it will not destroy your phone.

Hope i could help.

2% problem solved for me (LG G2)

My D802 was stuck on LG logo with a modified rom installed.

After several tries with different PCs I gave up with the kdz method and tried the LGFlashTool for tot files.

Found that my main problem was the OptimusG3 rom which changed my device ID to D855 (G3).

I found a generic DLL ("LGUP_8974.dll") which helped me to get past this error and to flash a 1.0B firmware tot.

Afterwards the LF Flash Tool 2014 worked like a charm and I could flash the 2.0h firmware.

My phone is back online. :good: My problem was in the phone itself and not on the PC.
