lg g2 d802 İMEİ NULL REPAİR

We will repair phone with only 2 programs. You needn't QPST, qcn, etc.

I already haven't qcn backup, so i failed to back up and change it.

İf you did number 4 before, just do number 2, reset phone. Your imei will come back.

Necessary programs: I used theese, you can use newer versions.

Minimal ADB Fastboot v1.1.3

EFS Professional 2.1.80 beta

1-)Connect the phone "Lg Software", you will see in device manager (com&lpt) port.

Driver I used: LGUnited MobileDriver_S51MAN313AP22_ML_WHQL_Ver_3.13.2

Device manager -> androidnet usb modem #2 -> modem -> The fastest connection=115200.

LG G2 D802, MSM7945, SNAPDROGAN 800, ANDROİD 4,4,2, V20c, Made in Taiwan.

2-)Phone should be root.

İf your phone doesn't seem with root in ADB FAST BOOT: uninstall supersu, install again form google play.

I uninstalled supersu, installed superuser# from google play.

3-)We will just here enter 7 commands.

Install ADB FASTBOOT and open, enter commands one by one.

........Enter “adb shell”. You will see *Daemon not running, starting it now on port 5037 *Daemon started

succsfully* shell@g2:/$ .

........Enter “su”. İf you see 'not found', your phone is not root.

........Enter “setprop sys.usb.config diag,adb”. Port will opened.

........Enter "ls -al /dev/block/platform/msm_sdcc.1/by-name".

After this command, you will look for: modemst1, modemst2, fsg

lrvrwxrwx root root 1970-01-03 03:31 modemst1 -> /dev/block/mmcblk0p10

cblk0p10

lrvrwxrwx root root 1970-01-03 03:31 modemst2 -> /dev/block/mmcblk0p11

cblk0p11

lrvrwxrwx root root 1970-01-03 03:31 fsg -> /dev/block/mmcblk0p16

p16

İmportant is last numbers here, mine is 10,11,16. You just change theese numbers with yours.

Enter 3 commands below one by one, by changing only with your last numbers.

......dd if=/dev/zero of=/dev/block/mmcblk0p10

......dd if=/dev/zero of=/dev/block/mmcblk0p11

......dd if=/dev/zero of=/dev/block/mmcblk0p16

If you didn't do these commands, qv nv items fails.

4-)Go into Qualcom Nv tools in EFS PROFESSİONAL.

You will see LG Andoidnet Usb serial port (comx) on top and connect.

If it is not connected, go to phone: Settings->general->pc connection->tethering and connect.

If it still fails, get empty "send pc" box in qualcom nv tools program and connect.

İf you connected, read phone info and go into secure ops. tab.

You will see 3 boxes under MEİD/ESN/İMEİ REPAİR in secure ops tab.

We will just fill them and write phone.

First we should learn Meid hex, esn hex, imei dec numbers from meidconverter.com

Meid hex is the first 14 digits of our 15-digits IMEI number.

Write your meid and convert in site. You will see screen below.

Format	Value

Hex ESN

Decimal ESN

Hex MEID	3xxxxxxxxxx8

Dec MEID	08xxxx7845xxx3448

Pseudo Hex ESN	80DBxxx7

Pseudo Dec ESN	12xxxxxx207

IMEI

MetroPCS SPC	7xxxx0

We just need here: Pseudo Hex ESN. Because it gives us our 'esn hex' value, 8 digits mixed with letters.

'Meid hex' is the first 14 digits of our 15-digits IMEI number.

'İmei dec' is our 15 digit imei numbers we knew.

Write these in Nv TOOLS, tick the boxes and write the phone.

Finished.... When you reset the phone, your imei will come back.

If your phone keeps restarting, first press power button 30 seconds. You sure phone turned off exactly.

Press and hold volume+, plug suitable usb cable until download mode.

While you are connected pc in download mode, use B2CAppSetup program.
