Repair IMEI LG G4 "TMobile/AT&T" - GSM-Forum

What it dew people....
Since i have not seen any box support for the LG G4 "Tmobile/ATT"
Here is my way of IMEI repair for the LG G4 without a box!

Since we are going to be using "adb shell" to wipe the IMEI, you will need to Root your device
go to this link [ROOT] TMO/VZW/ATT/SPRINT/INTL Root your LG … | LG G4 | XDA Forums
Follow the steps carefully! and give a thanks to "thecubed" for Root method!
Make sure you make a back up of your QCN before trying this you will need this at the end!
You will need "QPST" after installing it enable "diag mode" from your device plug into your computer
Open up "QPST Configuration" go to "Ports" and "add New Port" and you will se your Serail Port highlight it and press "OK"
still with in "QPST Configuration" go to "Start Clients" and go to "software download" you will go to "Backup" and "Browse" to where you want to save your "QCN Backup!"
Close "QPST" and open up "Command prompt window" with in your "adb folder"

Send these commands..

adb devices "your device should pop up"...
adb shell
su "make sure you grant access"
dd if=/dev/zero of=/dev/block/mmcblk0p24 "first command"
dd if=/dev/zero of=/dev/block/mmcblk0p25 "Second command'
dd if=/dev/zero of=/dev/block/mmcblk0p26 "third command"
and reboot your device ....

Open up again "QPST Configuration" add again your "Lg serial port" go to "software download" and "restore" your "QCN" and "Browse" your "QCN" that you backed up ealier!..
and finally you can use either "EFS Pro/CDMA workshop(paid version)/DFS Tool" and write your IMEI! reboot DONE!...

NOTE: if you still having issues trying to connect to the phone send this command with in "adb shell"
echo 1 > /sys/devices/platform/lg_diag_cmd/diag_enable

If you still need help send me a msg and I will try to help you ....

I'd like some help with getting this started if possible. I've tried PMing you, but it doesn't seem to go through.

shabaz9786 · 10-11-2015, 00:24

Does it work on LG G4 H811 and AT&T version??

brazzle · 10-11-2015, 03:51

How do we write a new IMEI with the EFS Pro program?

ownmart · 10-12-2015, 00:36

follow the intructions to a T then see if it works, says you can use workshop or qpst, you'll have to search that part

Open up "EFS professional" select "Qualcomm tools" select your Serail port of your device ...

under "Secure Ops" Check "IMEI" input your IMEI .. reboot...

---------
DFS tool

Open up "DFS Tool"
Select your port..
Write your IMEI under "Programming" reboot...

You will get your 4G LTE if you backup your QCN before you started the process

shabaz9786 · 10-13-2015, 07:14
