[Q] P700 stuck on LG logo - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

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

[Q][L5] IMEI lost and SIM not recognized

Hello
I'm having troubles with my new LG Optmus L5 e610. It comes oot with 4.1.2 and the LG mod v20b.
I rooted it with the v20d_root.kdz and now i've installed an unlocked bootloader, CWR, CM10 and Gapps. I have now a problem: the IMEI inside the information menù is empty and every SIM card is not recognized.
What should I do? I tryed going back to the stock the reflashig all, but nothing. By the way the stock ROM works fine.
Investigating around i discovered the same problem over many Samsung devices, with following solutions talking about this EFS folder that needs to be backed up. Googling around i found that LG don't need to back up this folder. Am i wrong?
EDIT:
Googling around i discovered that flashing a rom fro the v20_root may cause this issue, so it is advised to downgrade to the v10. But how i do it without making the kdz flasher give me errors? And which one of the v10 kdz i have to flash?
Hello,
You must install v10 baseband.I'n on mobile now and u can't help you but serch on google for it.

Strange touch problem after upgrading my lg g2

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?

[Q] Help with VS980

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?

[q] hard bricked lg g2 d802 . No download /recovery/fastboot mode. Pls help

hi,
i'm from india .
i had installed lollipop 5.0.2 v30b via kdz flash method on my lg g2 d802 (indian version ) .
since then i had issues wirth my bluetooth and wifi.both were not working .I Tried flashing back to 4.4.2 stock and other custom roms.
everything worked except bluetooth and wifi.so i flashed back to lollipop v30b 5.0.2
further ,in my attempts to flash back to stock 4.2.2 , i came across A thread ON XDA (http://forum.xda-developers.com/lg-g2/development-d802/rom-stock-30d-flashable-zip-t3070383) and i flashed "D802_PATCH_RETURN_KK_droidth" via philz latest cwm recovery ,
but after that everything went mayhem ..
i got boot error message repeatedly and was unable to enter even recovery .
after several tries i somehow managed to enter recovery mode , but stil phone wont go past it.
I GUESS I ACCIDENTALLY FLASHED A KERNEL FOR MY OLD GALAXY NOTE(due to confusion between the saved files in the download folder ) , On my g2....but i'm not sure if its the cause of the present issue...
after i restatred the moB , it wont turn on .
battery was 85 % ..
i'm not a newbie to flashing roms and have done aTLEAST >50 times with my lg g2 and galaxy note 2 and previously sgs2 , but this is the first time i got into a hard brick mode.
when i took the phone to servie center, they told the mob is just out of warranty and so wont get any warrany related help.
they told that the EFS HAS BEEN CONVERTED TO READ ONLY mode somehow due to improper flahing and also added that the EFS IS BEING SHOWN AS 16 PARTITION S.
they tried to repair the boot sector and recovery using OCTOPLUS TOOL BOX , but failed and told me that the latest models like G2 is not supported as if now in their TOOL BOX.
THE ONE suggestion given by them was change of PCB which is almost same as a new mob.
I'M STUCK WITHOUT MY FAV MOB G2 .......PLS HELP ME OUT SOMEHOW AND HELP ME OUT...

Help Broken phone ?

Hello i have a problem with a friends LG G2 I flashed it lolipop 5.1 and then i wiped the whole internal storage clean and installed new firmware on it i tried flashing 4.4 the second time then the phone did not boot up and the screen was stuck to an error message cant quite remember it.
Anyway my friend sent it to lg and they said to him that the phone was double flashed and it could not be fixed... I need to know if i can recover the phone and if so detailed steps if possible.
Thank you very much (The phone has access to TWRP recovery.)
Please guys it is very important i need help with the matter
It can be unbricked. Your problem was probably flashing wrong bootstack since you got security boot error.
First, if you can get into download mode, do tot/kdz. There is guide here on xda
