[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] LG G2 d802 completely ruined...help!

Hi all, hope you can help me. I've tried searching on the internet but no-one seems to be having any problems like mine. and my phone is now near enough bricked.
So i bought a LG G2 D802 from aliexpress, all working fine but no 4g lte option for some reason. Had a look around and seems updating to stock europe rom would have sorted this so i thought id do this.
So Updated the rom using flashtool2014, downloaded lg usb drivers, the europe rom D80220D_00 and lgmobile support tool. Went through the process and it all ran fine with no errors completed 100%and then said done pressed exit and disconnected phone.
Now, switched phone on . Straight away touch completely messed up click on the screen and different parts keep of the screen keep clicking. Eventually after 15mins managed to get out of the startup where it asks for wifi settings etc so i could try to factory reset. No luck even out of startup have not yet managed to get to the screen for usb debugging yet due to random screen clicking (keeps opening other apps, screens).
I cannot rerun the flashtool as i cannot enable usb debugging or even switch away from charge only to pc softwarw and it just says phone not connected on the flashtool and keeps ending.
Switched off by holding power button for long time. Holding down the down button and power does nothing just keeps restarting when i eventually let go.
Also sim is in phone but it says service disabled?
Any ideas how i can fix the phone! All was working fine before I did the europe rom update
Thanks
Jon

You can connect a mouse via otg and navigate to usb debug

I eventually managed to select lg software as connection mode and flashed to another firmware but exact same issue again.
After trying for ages and opening the wrong thing again and again i managed to get to the screen in settings to click 5 times to enable developer options however now the screen just freezes and then you get a message saying settings has stopped working and phone locks up. This has happened 3 times since. Doesnt seem like anyway to get it sorted if i cant enable usb debugging.
Also it seems to be that the firmware change has erased the imei and that is what is causing all these problems. I found one site that details how to restore but once again you need usb debugging enabled.

Droidview has the page where you have to backup and restore imei, i dont have a backup so will need method 2. If i can get usb debugging enabled that is!

Try using onscreen phone maybe you could manage to set that up and then enable usb debugging?

thanks for all the help, lg on screen just didn't work for some reason wouldn't connect to the phone. Was thinking about a otg cable but after an hour of clicking again and again I managed to get the developer options and usb debugging enabled.
I went through the procedure at droidview to restore imei using qpst but after finding the com port it says no phone detected so theres nothing more I can do, looks like I just have to accept this brand new brick lol.
Anybody know anywhere in London that does repairs like this, I have tried a couple of shops in London Victoria near work but they couldn't do anything. Apparently theres something called an octoplus/octopus box that can fix LG G2 imei or flash firmware.
Thanks again for everyones suggestions. .

Jon-jay, I have the same issue. I tried the "easy" kdz flash and tot flash and basically bricked my phone. The phone turns on but the screen is calibrated incorrectly like you describe so I can't click anything without trying over and over. I click one area of the screen and another is activated. I can pull down the notification pane but can't click anything in there. The phone is in a boot loop too if I don't touch it. I also want to turn on USB debugging so I could try to restore with adb or fastboot. I will let you know if I find anything.

Yeah very tricky to fix this phone after flashing. Ive flashed loads of lg phones with the flash tool and never any problems until now. Ive currently sent to a shop in south wimbledon who quoted me £50-£80 for repair if he could fix it. I dropped it off on mon and still no response so im not holding my breath. It seems this phone will be going to the recyclers if he cant do anything.:crying:

Check out the thread lg g2 is unbrickable now, it involves shorting a couple capacitors to unbrick but its ingeneious. I bet itll help you out.
.::.LG G2 D803.::.
.::.CLOUDYFLEX 2.7.::.

the plot gets thicker...
okay so it has been a few months now and I revisited the phone sitting around. This is how I got on:
I gave the phone to shops in London, no-one could fix it got it back first week of Jan. So I thought I'd retry myself.
One guy told me that the imei may be for D802 but the screen and insides of the phone is a d800 model.
That makes sense as the touch works erratically. This was a refurbished phone I bought from aliexpress which claimed to be a EUR D802 but after I took the back cover off it says D800\d801\d803 inside on a lot of the flex connections and at the bottom of the plastic it says d800. I downloaded the AT&T stock rom and flashed with octoplus - touch worked perfectly! but phone kept restarting itself and looping really badly so I put in download mode and went back to D802 uk firmware - and touch not working again.
(Prior to this I bought the octopus box also in the hopes that restoring the imei I had previously lost will somehow be related to the screen.
This worked in restoring imei only and I have restored the d802 imei with octopus box)
Anyhow I then flashed stock uk firmware on the phone so everything in the phone works perfectly fine except the touch! so I am controlling touch with otg cable and mouse.
my next thought was install a d800 custom rom it will fix the touch! Now I then rooted, and installed d802 autorec.apk. I came on xda and downloaded a d800 stock custom rom (D80020k) from the AT&T subsection and thought I'd install this through twrp. All though the custom rom says successful when I reboot it comes to fastboot mode again. so I then go about restoring the stock d802 firmware. I installed d800 autorec.apk but that too send to fastboot mode.
So I am lost. Everything working perfect except the touch. Any ideas anyone? Im hoping some one says there is a stock lg custom rom that has all the screen settings for d800/01/02/03 which will sort my problem!
What it seems is the chinese company selling the refurb has somehow managed to get a d802 imei on a d800/01/03 not entirely sure how this is possible either!

What they're doing is flashing a d802 system.img with otherwise d800/01/03 firmware.

I saw a thread in the T-Mobile G2 area saying to get d802 on your d800/d801 you just flash a custom d802 rom and then a d800/801 kernel but this causes my phone to go back to fastboot...still lost! the custom rom works fine itself (Except for touch again!)

There is a way to get them back to their original frankenphone state but it's quite a procedure. Flash d802 firmware. Use a otg usb mouse to navigate since it'll have touch issues. Root and install custom recovery using the actual hardware as your guide to which twrp version to install. D800 in your case. Do a nandroid backup. Move the nand backup to your pc for safe keeping. Now install d800 firmware using a hex edited tot to allow it to proceed and a generic dll to avoid cross dll issue. Root, install twrp again. Move twrp backup from pc to phone. Do a restore but only restore the system.img. Now you have firmware that cooperates with d800 hardware while appearing and acting like a d802 in every other way.
The other thought I had but have not tested yet would be to flash d800 firmware right off the bat, then root and install twrp. Then use dd to flash system.img to it's partition ( /dev/block/mmcblk0p34 ). I'm not sure how that would work due to the very large size of the system image. You'd have to extract it from the kdz. Because it's so large when it's extracted, it does it in parts so it must be merged back together to make one file. But if it did work, it'd save the step of having to root/recovery twice on two separate firmwares.

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?

Nothing was loud thinking but cant help you here anymore sorry told you everything i know

my LG G2 went crazy after i tried Lollipop update

hello, so it all began with the lollipop update, i wanted it on my new phone (less than a week old), so i've read everything i can about flashing the G2, and i guess i did nothing wrong (i used normal flash instead of CSE the first time), but i didn't back up my original ROM and that's the problem, so the KDZ installed normally, but when tried to configure the phone, the touchscreen went crazy , exactely like this https://www.youtube.com/watch?v=hYwumfkokOA. so i downloaded a 4.4.2 kitkat rom, but it didn't correct the problem, i used an OTG and a mouse to use the phone, and i found out that my IMEI is "null", and there is no signal at all, plus the phone heats up and the battery drains really fast, and some apps like the browser freeze when i open them, i tried at least 5 roms, and they all have the very same problems.
then i tought maybe my phone isn't a d802, so i checked my IMEI on every IMEI check website, and they all told me it's a D802, but when i removed the back cover, i found "D800 0815" written under some sticker, and i'm afraid that i'll brick my phone if i try the stock d800 firmware, and it's android 4.2 while my original firmware was 4.4.2, i even took my phone to a repair shop but no luck, i'm really confused and can't replace or buy another phone, all my savings went into this one, and this forum is the only place that can help me, so please, if anyone has a solution help me
TL;DR: my touchscreen went crazy and my IMEI says "null" after i tried a lollipop update on my LG G2 D802

Where did you got your phone from?
There are a lot of shops selling refubished D800 or D801 as D802. They replace the Model number in build.prop which is a simple trick. Then you get flashing errors and other crazy errors.

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.
