Hello,
today I went to downgrade my L7 from Carbon ROM to V20A with CWM/ROOT by Homero using KDZ and when phone restarted after upgrade it got stuck at LG logo, so I tried flashing multiple times but it didn't succeed.
I couldn't even access the CWM, I tried almost all unbricking solutions.
Now I tried even with official LG Mobile Support Tool which updated firmware to V20D and it won't boot up.
a) Is there a way I can back my phone to get it working myself?
b) How much will the service cost as my warranty expired?
Thanks a lot!
Anybody?
Please, I really need to fix this device.
EDIT: Solved.
reinstall rom, maybe this can help u
Hello Experts,
===========================================================================================================
Update - 08/Jan/2015
I tear off my set & found several things
1. My back cover, settings > Software info & booklets shows it D802, while internal plastic is labeled as D800 & Motherboard is D801 T-Mobile. Look like some company is selling T-Mobile as D802.
I read it on this forum that if flash D802 rom on T-Mobile D801, then need to reload Kernels of D801 too after flashing D802 rom. I tried flashing D801 kernel in recovery mod but it gives error "E invalid certificates" or something like this, I also tried flashing D801 stock rom, but LG Flash Tools 2014 gives error at 2% (Phone disconnection & sometime "Connection to server failed"), however, LG Flash Tools flash D802 without any issue.
Now, can someone tell me how to flash D801 kernels after flashing D802 rom? Or how can I flash stock D801 rom?
===========================================================================================================
I am facing quite odd problems. please help me.
I have LG G2 D802. My software version was d80220b while when I attached my mobile with pc, pc suite notify me that d80220c is available. I upgraded. But after upgrading, touch is totally out of work. Say like below, I tap "7" & it goes to 2, 3 etc. I select say first option, it selects 4th option.
Also, one more thing, my mobile is 32gb variant, while now it's showing only 10.7gb.
Three Problems total
1. Touch totally disturbed
2. Storage reduced from 32gb to 10.75gb
3. Service Disabled (No sim is working :'(
I think it's due to some rom issue, can you please guide me or send me link for the correct ROM for my mobile?

Hello everyone, I have the Verizon LG G2 and it thinks it's a different g2. I have edited the .tot's to other device models and it still won't work. I have followed many threads and none are working for me. I also did try the .kdz method which kept getting stuck at 2%. I also do not have twrp.... My question is is there a way to install twrp right from download mode to try to flash the right software to get it working agian? Or does somebody think they can help me figure out the problem with the download mode restore?

a few feeks ago bought a second hand lg g2 d802 running kitkat 4.4.2 wich was only detecting 2g when i try to connect to the internet, i tried to solve this problem by entering the hidden menu and selecting the network types it could detect but no luck, so i decided to upgrade to lollipop, i downloaded the lg support tool and went for it, when the update was done i found myself with an almost completly functioning device except it had the "imei=null" problem, meaning no network at all --"
i tried the QPST but it was unable to detect my phone, so i decided to root my phone and go for a custom rom, the cyanogenmod13 nightly (i don't really know what i was thinking at that point :s ) and when done i was stuck in a bootloop, so i tried flashing a stock rom kdz method but the lg flash tool would stop automatically. since then i've been trying to flash stock TOT roms, the process would stop at 94% and the phone reboots. the screen shows random pixels and lines, the start up lg tune is there and i feel vibration when i press the home buttons location, i've tried to reset it to factory settings and i've used theLGUP_8974.dll, selecting the BOARD DL option in the lg flash tool but that didn't solve the problem. i have read somwhere that it could be a kernal problem, i don't know if i should go that way ( am at that point where i don't want to mess up my device anymore xD ) what do you guys think?
thank you for your help

Sounds like to me you may not have a D802. You'll need to take the back cover off, and look and see what model #s you see. As if your having screen issues that sounds like your flashing a D802 firmware on a D800 or D801.
Also remember flashing will almost always stop before 99%.. Anything after 85% its done this is normal and will almost always happen.
These D802's have a LONG history (mostly bought referbs) of not being what they are being sold as.
