[Completed] Half Dead LG G2, No use of touch, imei, network

I have been stuck for over a month now and now I am forced to make this thread with the full story:
I bought an LG G2 D802. A few months later I updated it through the LG software update tool. This thing killed my phone. It installed lollipop and I then had these issues:
[1]no imei.
[2]no baseband.(FIXED)
[3]touch is not working properly. It is haywire. It does not respond properly at all and the phone is unusable
[4]no sim usage as no IMEI.
[5] ONLY 16 gb showing as memory available. (FIXED)
I did this. Using OTG to use my phone, I flashed stock d802 ROM (kitkat). This got me to Stock ROM but phone was boot looping. I factory resetted and it started up okay. I then found a way to fix the 16 gb issue by using a droid view guide called : "Your 32GB LG G2 Shows only 16GB Storage Space? Here’s How to Fix the Issue! " This fixed my 16 gb issue. But everything else same... Then I followed a guide to fix ESN but it demanded that the phone be rooted. So I rooted and installed TWRP. But I was not able to fix IMEI. So I then gave up I searched my issue extensively and found a thread (ON XDA) which i cant post here... But its name is: "Strange touch problem after upgrading my lg g2". There I read of other people who had the same issues. This basically happens to refurbished handsets, apparently. There where no proper fixes there. None of the people where able to fix their phones.
Some guy said that check your motherboard and install the software according to the motherboard. I opened the board and found it to be a motherboard of LG D801. No problem. I downloaded D801 software and tried installing with kdz method but it failed. And now so has the tot method. I have downloaded over 20 gbs of different software and roms. ALl of these roms where completely downloaded!! Please help me here...
Its not me only: These threads are after the same issue!!:
1. Name is: (on XDA) "LG G2 No IMEI, Touch not Responding After Update" (One person)
2. Name is: (on XDA) "Strange touch problem after upgrading my lg g2" (MULTIPLE people withe SAME issue)
I am not an advanced android guy but I can follow directions and I have adb, root, twrp, qpst set up.

Can you be more specific on the error when using KDZ and TOT? Please post a screenshot.

The kdz method just fails at 2%. But the tot method works. I installed jellybean to see if that fixed the problem But no go. Still have no touch screen and no IMEI. The major problem right now is touch screen ONLY!
zhzhou said:
Which TOT did you install? D801 or D802? I think it should be D801 because it matches your motherboard.

I agree that I should install tot of d801 . But the install fails. I tried using the LG_UP 974 dll file but that does not work too! The error is alwasys wrong model number. The TOT method works for d802 roms.
I am wondering. Should I flash a kernel of d801?
hyelton said:
Well that can happen if you flashed the WRONG model for your phone, and youd need to flash the correct model to fix it.
or 2 its an hardware issue.

Hyelten some help would be dearly loved!

You should install the D801 TOT. Here's how to do it.
1) Download D801 TOT
2) Download HxD hex editor
3) Open D801 TOT in HxD
4) Find first instance of "D801" and change to "D802"
5) Save new TOT file
6) Open Flashtool and flash the modified D801 TOT that you just created (use the LG_UP974.dll)
This should work to get D801 firmware onto your device.

Any possibility of hard bricking my phone??

I did what you said and changed the first instance to d802. Now a new error dialog appears saying: "failed previousload()"

It's unlikely you'll hard brick the phone. You've already put the D802 firmware on a board that you've confirmed is D801.
I had wrong firmware and subsequently lost the IMEI. I flashed the right one firmware (after modifying TOT because of model mismatch error), and the IMEI came back.
Isn't your phone pretty much useless already? I think the steps I described above is pretty low risk. You can find the answer pretty quickly by just doing it

[Completed] LG G2 D802 Refurbished, problems after upgrading rom

Hello to all and hope you will be fine
My Problem: i bought LG G2 D802 last week, it was running on 4.4 kit kat, i thought to root my phone and to install android 5.0,
So i use " one click recovery" for rooting but sudddenly my phone stuck in fastboot mode, after a lot of search i find a solution with LAF, BOOT, ABOOT etc, but i flash these .img files of d801 unfortunately. after that in download mode i installed KDZ, for turned on but touch is not working its awkward.
After searching lot i find that my LG G2 is Refurbished. i opened it and see the motherboard and D800 was written on it. So it is D800, but it always shows d802 in adb.
After doing above all things what happened to my phone
No network
Baseband Unknown
Imei Null
Touch is not responding
Internal 32 gb but showing 10gb
Restarts after 1 or 2 minutes
im currently using it with Mouse and so worried as i had managed money with great difficulty. :crying:

[Completed] Unbrick LG G3 Beat D723

Quite recently i recovered my Beat when i managed to soft brick it and it just booted into fastboot mode or whatever you call it (im a newbie).after days of searching the web i managed to find something called LG Flash Tool from which you can flash a .kdz file which i think is a firmware file .You can find how to use the LG Flash Tool from here Mod Edit .You need to download the firmware file and i downloaded it from here Mod Edit (im guessing it works on other models as well such as the D722 or the D724).
Once downloaded you need to open the LG Flash Tool and select the firmware file you downloaded and select either of the two flash options (normal being for the one with your data being recovered and Csu the one with your device being wiped ) i did the csu as i had already messed my device up .I hope you find help from this thread and manage to recover your beat and best of luck to you all.
Greeting,
XDA Assist is not the correct section to post this in.
Please re-post in the device specific forum.

Thanks,

[Completed] LG G2 Touch not Working After Software Update...

Hi,
I have Lg G2, and I upgraded it Android Lollipop using Lg PCSuite. After the completion of upgrading my Cell phone Touch screen is not working properly, as I touch on the top of the screen and something is touched on the bottom of the screen.
Now, I used Lg Flash Tool to Downgrade it back to the old Kitkat rom, I found tutorials from here and I downloaded .tot file for Lg G2 D802, it flashed properly on my cell phone but the problem is same.
Then, I searched few threads here where I found that this problem occurs when you upgrade to a non international version and I must open the backcover and see the original model, where I found LS980 written on the back. I downloaded .tot file for Sprint and now when I flash, it says like that you cannot start install on D802 with LS980 Bin file..
Please Help

LG g4 correct kdz ????

A while Back i tried to update my LG g4 H815T to marshjmallow using the LGUP method. I followd the thread on XDA.
When I was finished with it my phone got soft bricked. ( It booted up bu tgot stucj on the LG logo and blue LED flashed continiously.)
I tried using the same method but this time LGUP was not even recognizing my phone. Then I started searching for other methods i.e LGFlashTool but that didn't work either so I gave up on the phone.
The other day I was just sitting and realized thatthe issue may be that I flashed the wrong KDZ. Since the link that was provided to all the LG KDZ didn't have a file named just H815T.
Now I searched the internet but couldn't find out what KDZ to use. Any help would be really appreciated. Also, If someone thinks there could be another fix please do share as I'm not a 100% sure that i'll unbrick my phone even if I do find the correct KDZ.
here are the links i reffered to
the tutorial I used:
http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
