[Q][L5] IMEI lost and SIM not recognized - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

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.

[Q] Strange touch behaviour after Stock Rom flash and root befor

Hi there,
I realy need your help on my problems with the G2 32GB D802.
I bought it on ebay and instead of getting it from GB it came from HongKong and I didn't think about it that it does not have a european ROM.
First I wanted to root and flash custom recovery and cloudyG3 rom. After rooting with ioroot and installing the TWRP I stuck in the fastboot mode. First problem I did not make a backup because I never reached TWRP. Download mode only appeared for a second an then disappeared again.
After a lot of searching I found that probably the 802autorec.apk was wrong, since I don't have a european model. So I installed via fastboot a laf.img for a D800. After that the download mode was working again and I installed different roms via flashtool2014. The installation worked again but after rebooting the phone I had a lot of trouble with it. That the reason for trying different roms as I sad befor.
First, the fingertip points at different areas of the screen but not there where you are touching the screen. So you can not reach the buttons or write on the keyboard.
Second, after connection to pc I recognized that my 32GB model had only 10GB internal memory.
Finaly I can not use the phone. For me it seems that I burned my partitions and need your help to get it right again.
Please give me a chance.
Best regards an thanks for helping me.
p.s.: I tried to go to the settings menu in the phone and reached it after a lot of confusing taps on the screen. All the phones informations like IMEI and all the other disappeared. Something realy went wrong with it.
No one an idea how to get back to normal?

I now have the answer from the dealer that my G2 has the Firmware D80220B.
Just try and test it. Good luck.
@Angryyolk
I just ask myself how to enter engeniering mode?
Thanks for your help.
I walked one step forward now.
But there is still no solution for my problem. I found a link to LG "http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI" to get the information about the version of my stock ROM. Just replace IMEI by your real number and you will get it.
In the meantime I flashed the rom with flashtool but the screen behaviour is still the same.
I later rooted the phone with towleroot and then installed the correct autorek.apk for the D802. That worked properly. I reached TWRP but in fact of the weired screen behaviour I couldnt do something. I tried to fix my IMEI problem with QPST but this tool showed only empty tables on my PC when I connected my G2 with usb.
I tried an update of the screen firmware as posted above. The code that has to be entered on the dialer is 3845#*802# but it wont work for me since I can't enter "settings" the service menu. That's because of the weired behaviour.
Beste regards
I now was able to enter the hidden menu. And I was able to get to the menu point "update touch firmware" but nothing happend.
What is wrong?

[Q] P700 stuck on LG logo

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

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 Going Back To Stock!

Hello guys, I have a D802 phone and I was on Ressurection Remix 5.0 but since the official lollipop update was made avalaible, I wanted to return to stock and unroot so I could again use my warranty(for some weird reason they couldn't tell last time I took it there that it was rooted). Basically my problem is that every guide for going back to stock has the phone connected to the PC and use the flash tool. Well, I did that but when the mobile support tool opened for the upgrade, it couldn't find my phone. So I found a guide that showed you how to extract and rebuild a kdz file into a .zip. I tried that, used the UK d8023b rom ( A friend of mine who has a d802 as well, though unrooted, got the prompt to update through the pc suite and it updated his phone to d8023b, thats why i used that version), flashed it and I am now stuck in a bootloop. I have full access of recovery and adb but the phone isn't recognised by LG software. Can you please help me use my phone again? Going into download mode didn't work with the flash tool.

Misc files over 20 gb?

Hello guys, I hope you can help.
So, last week I had a problem with my lg g2. When dialing a number it would show the wrong contact number, so I thought, what the heck, I'm still with KK (I'm lazy), time to upgrade! I've flashed a rom but something went wrong and I softbricked the phone. I was able to go into download mode and restore the latest official LG firmware (I made sure to download the 32gb version of it). However, now I have 21.87 gb of Misc files and I have no clue what they are or what is the problem. Ideas? Thanks!
No one, pls?
Hi.
Got the same problem. It happened exactly after the failed upgrade. Tried a number of things (including returning back to the KK and rooting the phone). Unfortunately failed to find a solution.
Does your sim work and is you screen messed up?
Have you tried to look into those Mics files?
