[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?

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

LG G2 display problem after going back to stock

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.

Please One of main forum rule is dont bump threads. I know youre in a rush because u wanna know whats going on on your phone but keep this in mind.
My suggestion. Get Samsung Kies, hook up your Phone in Downloading mode and do a total restore. If this will not help you can also try samsung firmware downloader and flash everything custom to stock via Odin. Try first method if this will not help, pm me. If the hole thing will not work i think your EFS partition is bad or corrupted maybe.

I had a similar problem, the only way I managed to fix it was by using Samsung smart switch. Here's how:
I am not responsible if this ends up destroying you phone
1- download Samsung smart switch to your pc http://www.samsung.com/us/smart-switch/assets/downloads/Smart_Switch-PC_setup.exe
2- Put your phone into download mode ( Turn off your phone, press the volume down + home + power button together and then press the volume up)
3- connect your phone to your pc via USB cable
4- open Samsung smart switch
5- on the top right there is a option button click on it
6- now click on emergency recovery
7- now click on device initialization tab
8- now enter your model name. For example: SM-G928C
9- now enter your serial number. You can find this in your box.
10- after that agree to everything and it will start downloading your original rom. This will take a while.
After that hopefully you phone will boot up.

allready tried everything you writte. didnt help. but thank you guys for helping

thanks for help grsjohn, i havent fix efs yet. because i dont have so much time. just reading a little a day about it. i havent any efs backup or something.
can you tell me little more about efs? can i flash efs or recovery it without box? if its hardware, how you fix baseband? i tried only apps what need rooted device to solve this problem(with no luck). nothing else yet
thanks guys for help to solve the problem

Hello, I had many phones from clients with your issue, it's a hardware issue, baseband got damaged, if you flash different firmware versions and fix efs an result is still baseband unknown for sure is hardware issue. Probably guy from who you bought that phone knew about this problem, baseband cannot get damaged after frp reset, I do this kind of operations often and never had problems

Galaxy S5 + Root safely.

Hi guys, today I made a big mistake by thinking that it would be so easy to root on my S5 +, I was wrong, because it appear that I had the bootloop problem, i resolved it by mistake i was so lucky, I tried to put a BootLoader on Odin on AP section, an error occured on my phone, It reset it and it did come back to life Yeah WTF right ? So now that i've got my phone back ! I'm happy but still, I'm worry about my sim and I want to know if someone is listening to me (because strange things happened lately), that's why I did some research and It appear that an app does exist to prevent such thing ! it's called Snoopsnitch, Amazing isn't it ?
I've got hope that you might be able to help me to root my phone properly this time and avoiding the loopboot issue. If you can led me to do it, it would be amazing.
There is my config. I wish you a good day, night or whatever you are doing on this planet. Kiss. :victory:

Thanks for your time and your answers guys. :highfive:

Oh hi, im having the boot loop / logo problem too.
could you explain more clearly what you did to resolve that and is it still good to this day?
ive already used odin3 v3.11 and put the latest stock firmware successfully but the phone still boot loops or if lucky it will get passed the carrier screen (O2) but then as soon as i restart the phone it will boot loop again. (or boot loop randomly, if i dont restart it myself, eventually).
I havent tried TWRP or PIT as im a basic user and just wanted the stock rom.
Any updated advice? ...im worried its the memory/emmc/hardware prob
thanks
