[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] [Help] Don't know What's the model of my s4

Hi guys,
I've bought a used s4, and after some time spended knowing the new cell phone I saw on the boot screen "Galaxy GT-I9515L" and start to look for a custom rom to this model. But there isn't any one right?
But there's some weird thing , in the back part of the cell where's located the battery is written model "I9505" and the box that came with it have the same thing, "model "i9505".
But when I tried to install a custom or the original rom for this version using the Odin an error message appears and I can't install. Then I tried to put a original lolipop version to "I9515L" and works fine whitout problems and errors.
So what can it be? Maybe the older owner had put an wrong rom? If so, how can I fix this?
Sorry for my bad English. Hope that you guys can understand and help me.
Thanks

Boot into download mode. There is your model.
Ignore everything else, just look at the download mode.

[q] help!!! D802 recovery/rom. Not an easy one.

It might seem like a simple topic with a simple answer, and a thread that shouldn't be created, but it's not like that.
The story goes like this. I bought a couple of LG G2's "D802" 32G (ill explain quatation mark later) from Alliexpress for reselling and decided to keep one myself. Being an android fan the first thing I would do is update the firmware or flash a custom ROM. So I tried to install TWRP with no luck, I bricked my phone (trying to get the phone out of the state of "fastboot mode only" resulted in hard brick, after that I sent it for warranty to alliexpress seller). I got a replacement phone, everything as usual, perfect phone from the first sight. Now to my question(s)... :
1. I checked the IMEI on Swappa, it doesn't even show what phone model it is. I tried to enter the IMEI to this site: http://csmg.lgmobile.com:9002/svc/popup/model_check.jsp?esn=xxxxxxxxxxxxxx for .img extractions it won't load as such IMEI seems to be not real!!!
2. After reading around I found this thread: http://androidforums.com/threads/in...-international-hong-kong-version-32gb.877957/ . It says here that IMEI counterfeiting is not a new thing and changing one model to appear as another (for example D800 to D802) is just a matter of flashing a modified image, thus resulting in wrong IMEI numbers.
3. Now the main question: How do I safely install a custom ROM for my particular model (ill check what model number is printed under the back when I get home)? Would flashing a recovery requires reflashing the phone to it's original state trough download mode , let's say to D800 partitions? Would model check when flashing wrong files prevent me from installing anything at all?
If someone knows how to deal with this, or maybe even had simillar experience could help me, that would be amazing. Thank you for taking your time to read and reply.

Okay, so I checked what's under the cover... Hidden under a few stickers I found that it's actually not a D802, but rather D801/D803 (that's what's written under the cover). So the phone is D801/D803 , the back cover is D802, the software is D80220b. Any ideas how to get to custom rom without bricking the phone??

I just booted to recovery and guess what, it's preloaded with working PhilZ Touch 6.25.4 - LG G2 (cm_d801) recovery. Where does this lead me to? Should I try installing a rom?

My divice is dying!!!

Yah, I'm serious! I'll tell you in detail.
Weeks ago, when I tried to flash stock rom, I made a big mistake that made my deivice hard bricked and then I found the reason in this thread: https://in.c.mi.com/thread-1095941-1-0.html.
I immediately brought my device to Mi Support Center, they made it alive but other problems came and I posted this thread: https://forum.xda-developers.com/mi-a1/help/help-soft-brick-t3860620 (thanks for people who tried to help me)
I found that my device lost persist partition, so that I flashed it, done, however, I relized that my device lost IMEI and BASEBAND, too.
I tried to restored my IMEI by QCN file but I only got sim 1 IMEI, I flashed BASEBAND and my deivice stuck in bootloop.
After a long time, I asked for someone to help but they couldn't do anything and then I found some problems.
1. IMEI dosen't show anything now and BASEBAND is unknown.
2. I can't flash Android 8.1 or higher versions on my device, it only accepts 8.0 and lower versions. If I flash 8.1, it continuously reboot when Android One logo shows up. But nothing happens when I flash 8.0.
Three days ago, I brought my device to Mi Support Center again, they said my mainboard is broken, it need replacing but I denied because the cost is too expensive, about $145. I took it back, tried to flash 8.0 version and installed update, sadly, my device is locked now and I can't flash anything. I think I can flash 8.0 via testpoint method, but the important thing is that I don't know what's exactly happenning with my device.
Why I can't flash 8.1 version and can I take my IMEI back?
I'm tired to find the answers days and I'm thinking to sell my death device with a cheap price about $40 for screen and camera only.
Someone help me, please!
By the way, I'm in Vietnam.

These files were dangerous dude and they brick parts of your motherboard like imei and baseband. So if you need a fix replace it

I can buy a new one with the cost to replace to the whole mainboard. In fact, I accept the thing that I can't use SIM anymore, I just don't know why I can't upgrade to 8.1 or higher

Note 4 N910C Emergency Call only (Not Registered to Network) IMEICERT:PASS (IMEI Ok )

Greetings Folks
I have a N910C and as mentioned in title recently I got stuck in to this issue
How it happened
I had CF-Rooted my phone and Odin flashed TWRP for custom ROMS so I tried a few and was not getting the perfomance thought SimplROM would do it for me in order to install that ROM it said in instructions to install latest Modem and Bootloader
So i tried downloading the ones given in v6C BL was downloaded but CP kept on giving me errors getting stuck at 7% on mega so being stupid I downloaded DPCB(MODEM) While ROM was offering DPK4
So everything went fine until after boot I realized am facing Not Registered to Network
Since I had experienced this before on other phone I went ASAP in dialer to check my IMEI & SN both are still intact
I knew about EFS unfortunately I backed it up on Phone Storage which was wiped for ROM and I forgot (So dont have EFS Backup )
I do recall years ago back when I had S3 I experienced this and sometimes flashing different firmware(CSC ,Modem) fixed it
What I have tried so far
I have already tried several stock ROMs most of em had DPI1 Baseband except 2 other ROMS no luck
tried combination file method too (the one that helps downgrade to kitkat i believe ) no luck
Tried XEO repair Firmware no luck
any suggestions ??
and on that contrary now that I am not on stock is there any way to find out which CSC and Stock ROM this phone originally was one or came with with IMEI or Serial I believe ?
Thanks in Advance

Anyone??

under the battery there's the serial number
install on your pc samsung smart switch program
run it with option of emergency software recovery - device initialisation
input the model of your phone
input the serial number
start
have patience and a good connection
your phone will (eventually) get the latest official firmware
https://www.blogtechtips.com/2017/06/24/easily-restore-samsung-device-firmware-with-smart-switch/
at least you'll have a working phone with stock rom
from here on you can try again and get informed better on what to do
good luck

Hey there bud I have almost tried most of fixes I could I'll give Smart Switch a try as I recall I checked before it didn't have initialization just the recovery mode, while in Kies 3 I did try initialization method by model and SN but it prompted device doesn't support initialization
Anyways do you think it could fix network?

Maybe restore the efs from recovery, if you have a backup that was working.

Yep. Same problem as mine. Im kinda lost now since i dont have anything; even in stock rom it cannot go beyond connecting to my carrier. It only able to read my contact.
Im guessing its a motherboard problem? Isnt it @w41ru5?

I don't know. Usually it's a modem issue when not recognizing the sim.
If it's a 910F snapdragon it might be the infamous eMMC issue.
If you have an EFS backup try to restore it from recovery TWRP.

Assuming its modem problem, its related to motherboard i guess, right?
Finally got the phone working, only to discovered that SIM not working. Really wasting my time and hype!
Plus, its hard to search for n910c replacement board here.

The firmware, not the physical one.
Did you try to flash the 4 files repair firmware?
This is an example, I don't know what phone you have
https://firmware.gem-flash.com/index.php?a=downloads&b=folder&id=7081
Did you try the SmartSwitch pc program?

"...4 file repair..."- what? Ive google it until im almost run out of data here and you have a possible solution? You must be active in note4 forum.
One thing i noticed that, the IMEI and Serial Number are different from the sticker included.
I will try it, but not immediately; waiting for thurday-friday for data renewal.
My phone is n910c
EDIT : just checked the page you gave. I have few question;
What should i do with the files? What are the step? What are the program needed?
Is it related to SmartSwitch as you mention; need to use it?
Thanks!

1. It's good you still have the IMEI. Not so important if they're different from the sticker. Where did you buy the phone from?
2. So if you go to check the 4 files repair, you need to search on that site the files for a 910C.
3. Did the phone worked on your country provider? If yes, maybe you need to search for the 4files corresponding to your region code.
4. These 4files have to be flashed with Odin
https://zfirmware.com/download-samsung-repair-firmwares/
5. SmartSwitch is an alternative to get the latest firmware for your phone according with the model and serial number.
https://www.sammobile.com/forum/threads/29914-SmartSwitch-Install-amp-update-or-replace-firmware

the "firmware.gem" are useless. the error says i need another package (i assume a quota) to download the needed files.
im currently testing "zfirmware", but have a doubt since it only give 1 type file (which country is it i dunno). but yeah, since my phone like that, it wouldnt hurt to try
EDIT : yep, nothing changed. the device not even bricked.

If something does not work, why do you give up so easy?
http://www.mediafire.com/file/a2fdo0xm9nat5jt/N910CXXS2DPJ3_N910CZTO2DPE2_ZTO.zip - this is marshmallow
https://androidfilehost.com/?fid=24269982087001472 - this is for lolipop
Put the phone in download mode, open Odin and try.
And try the smartswitch also.

I tried files from LP and MM. It didnt work. And also smartswitch.
I was hoping that it will brick the phone (if i ever missed a step or incorrect file) but it didnt.
Might as well try looking for replacement board (or even a refurbished note4).
Thanks though for the suggestion @w41ru5!

Greetings again folks reading your replies above I have been trying almost every fix there is out there
First of all about Emergency Calls Only/Not Registered on Network
It can be due to several causes its can be Hardware ie faulty modem
it can be bad network coverage
it can be bad simcard
it can be SW with EFS problems or maybe even on rare occasion a modem file that you flashed
EFS can be either bad IMEI with CERT : FAIL or Just Network with IMEI and SN intact
just dial *#0011*# and see if you have CERT : PASS ( also someone with good IMEI/CERT and working network can share screenshot so i can compare whats wrong)
I am certain mine is EFS related because it happened after flashing modem DPCB modem via ODIN (I had TWRP EFS backup but the blunder I made was backing it up on phone storage and being careless forgot it was there and was wiped for custom ROM flashing process)
So far what I have tried
Combination File Method (and even downgrade to KK 4.4.4 )
Repair Firmware that include AP,BL,CP,CSC and even PIT
Kies 3 or Older Smart Switch says (Device doesn't support initialization ) since initialization feature was removed by Samsung on newer Smartswitch(since it was being used for wrong reasons? read somewhere)
Several different firmware's
OTA update
My IMEI CERT says PASS if only we had a network patch like Ariza Patch (for Galaxy S3) for Note 4 then we would be in luck so far at this point I dont think flashing ROM's would even help with bad EFS our only luck is Box e.g Z3x or Octo dont know if we are allowed to talk about those here (ill edit post if not)
these box applications have Network Patch for most Samsung models but I don't see one for N910C in most versions
for those with bad IMEI they can try writing good cert or efs on note 4 since they have already lost it I am sitting on it because my EFS is good on that part and for some reason box app isnt allowing me to back up my CERT if I am able to back up current cert then ill give those a try but I would prefer current IMEI since in my country IMEI should be verified to use the phone or you have to pay tax
I know its Bad EFS for sure because using Box application I chose reset EFS(after backing up current faulty EFS with good IMEI) upon reboot phone's imei was changed with no SN network came back for few seconds then gone again ,this happened to many users that have tried resetting EFS so I restored my original EFS
if anyone here with N910C and root can give me EFS folder I can corelate if any file required for network is missing since i have good IMEI
Cheers!
