What is IMEI/MEID?
IMEI is the unique 17 or 15 digit code used to identify an individual mobile station to a GSM or UMTS network, without proper IMEI, you'll not be able to receive OTA update in some phone like LG G4.
Similarly, MEID is a globally unique number identifying a physical piece of mobile station equipment.
Anyway, this is your NV Data, if you lost your NV Data, your android device might not work as a phone anymore.
How to backup your IMEI/MEID on ZTE Nubia Z9 Max?
So here is a simple guide on how to backup your IMEI/MEID on ZTE Nubia Z9 Max, in case you accidentally brick your device and need to restore.
So let's see what we need first:
1. Your phone running stock ROM,a PC and a Micro-usb cable
2. QPST v2.7 Build 4.11 or newer
Now get the backup:
1. Connect your phone to PC
2. Bring up your dial pad, dial *#7678#, you'll see something like this, check "Factory Port"
3. Now open QPST configuration, you should be able to see your phone
4.Select "Start Clients"-"QPST Software Download" from QPST Config UI,
5.Select "Backup" from QPST Software Download, press "Start' and you'll get your backup in the "bin" folder of QPST
6.If you ever need to restore from backup, just do 1 to 4 again, and Select "Restore" from QPST Software Download, get your backup and hit Start
this might take a while and your phone will reboot when it's done.DO NOT UNPLUG WHEN RESTORING.
That's all, enjoy your phone.

Hello,
My phone: GSMART Roma R2 (Rooted)
I know there are a lot of threads how to restore IMEI but none of them worked when I dial up *#06#, it shows message with two lines containing "null".
I was using MIUI rom for a while and suddenly after I rebooted phone SIM was no longer recognized (before reboot I was playing with SWAP couldn't make it work so I uninstalled BusyBox (could that cause the issue?))
I already tried:
Engineering Mode: Displays "AT command is failed to send"
Terminal Emulator: Doesn't work
MAUI 3G: Flashing new IMEI changed nothing.
MTK Droid Tool - Changing IMEI did nothing.
SN Writer: Writing new IMEI changed nothing BUT when I choosed to read IMEI it successfully displayed both IMEI in the textbox. (So it looks like the IMEI actually is registered on the phone but phone doesn't seem to use it)
Manually writing MP0B_001 to NVRAM: Nothing changed.
I have used backup in CWM recovery to stock ROM, didn't work, then I did factory reset, didn't work, flashed back the stock recovery and installed update from Gigabyte site, didn't work. So basicly now my phone has stock rom, stock recovery, factory reseted and is rooted.
Thank you very much for any answers because I just fell hopeless about fixing my phone
Hi there,
I see you already posted new thread in the right place: [Q] IMEI null and SIM not recognized, nothing works
Please wait an answer there.
Thanks, thread closed.
Hi everyone, to restore my UMI Iron from a malware that ask every time after boot for privacy password had to flash the phone with sp tool, the device is back but lost my 2 imei.
On umi forum warned me that i would missed the 2 imei, and that should use to restore SN WRITE tool.
I follow the guide step by step but always end in error.
I think was because Iron device do not enter in Meta Mode, but i follow the same way to flash a new rom with SPFT: remove battery cable, wait to recognize it and plug it again,
but it seem's not working.
If i tried with battery off (same as to flash the rom with SPFT) seems to not recognize the mobile and report a time response error.
If tried with to connect the power off phone with battery plug in, report other different 2 error:
First - ERROR!! Prod_Info : Metaresult = SPMETA_DLL::META_LID_INVALID
Second - EnterAPMode[] : MetaResult =
SPMETA_DLL:;META_MAUI_DB_INCONSISTENT
I tried to restore my 2 original imei from box sticker.
