Tutorial [HOW TO][FIX] Recover your IMEI

DISCLAIMER

USE THIS METHOD AT YOUR OWN RISK.

THE TOOLS INVOLVED ARE VERY POWERFUL. THEIR USAGE IS VERY RISKY. BE AWARE AND PAY EXTRA ATTENTION TO WHAT YO ARE DOING.

I AM NOT RESPONSIBLE IF YOUR PC OR PHONE OR ANY EQUIPMENT ATTACHED GET DAMAGED / BROKEN / UNUSABLE.
I AM NOT RESPONSIBLE IF YOU SOMEHOW GET IN TROUBLE, HURT OR INJURED.

PLEASE NOTE THAT THIS TUTORIAL IS ABOUT RECOVERING YOUR OWN IMEI IN CASE IT GETS CORRUPTED OR DELETED. IT IS NOT ABOUT CHANGING YOUR IMEI TO A DIFFERENT ONE. THIS IS ILLEGAL IN MOST COUNTRIES. I WON'T PROVIDE SUPPORT ON HOW TO DO THIS. DON'T BOTHER ASKING.



PURPOSE

The purpose of of this tutorial is to help people recover their IMEI.

Flashing the leaked SFR (France) 4.1.1 OTA and then flashing back a stock 4.0.4 ROM might as a side effect delete your IMEI, "Settings / About phone / Status" shows "0". With an IMEI set to 0, chances are your phone can't register to any mobile network, meaning no calls, no texts, no data.
There might other scenarios which will end up deleting/corrupting your IMEI. This tutorial might help.


CREDITS

I take absolutely no credits at all for this. A huge "Thank You" to cellzealot for pointing me in the right directions in this post. From then, I understood the idea, the process and the required tools. In addition, I got some details from these threads:

- [HOW-TO][FIX] Repair your IMEI with QPST - updated w/ info. Thanks to PureMotive
- [FIX/TOOL] Backup/Restore/Fix IMEI Data Restore Tool Updated - Updated 9/04/2012!!!. Thanks to Peoplearmy
- RAZR M - USB Drivers and Flashing App. Thanks to compnird


REQUIREMENTS

- a Windows XP 32 bits PC (a Virtualbox VM works OK)
- Motorola pre-release USB 32 bits Drivers v5.9.1
- QPST v2.7.378
- Your IMEI: a 15-digit code

I won't redistribute any of the tools since I'm not authorized to, but I'm pretty sure you can handle this by yourself i.e check out the threads referenced in the CREDITS section...


FOREWORD

This method has been successfully tested on an XT925 running stock Orange (France) ICS ROM. IMEI was set to 0. Software was installed in an XP SP3 running in a Virtualbox 4.2.4 (Debian host).
Other people reported successful IMEI recovery with different setups:
- running XP in with VMware Workstation 9
- running the required drivers/tools in Win7 64 bits & Win 8 64 bits


PROCEDURE

1/ Install the Motorola pre-release USB 32 bits Drivers v5.9.1 on your Windows XP 32 bits PC. Make sure to install all the embedded drivers. Windows might ask you to confirm for each of them. Just go ahead.
2/ Install QPST v2.7.378. Microsoft Visual C++ 2005 Redistributable is a prerequisite.
3/ Boot up your device in BP Tools Mode (while your device is on, hold Vol-/Vol+/Power buttons for a few seconds until the screen turns black, then release Power. Another few seconds later comes up the boot menu. Release Vol-/Vol+, then quickly press Vol- a few times to highlight "BP Tools" then Vol+ to trigger it). The device will start as usual (with extra features turned on).
4/ Plug your device into your PC (USB port)
5/ Run QPST Configuration from your Windows Start menu. Switch to the second tab ("Ports") and choose "Add new port" (bottom left button). You should see a COM port associated with "USB/QD Diagnostic". Select it, then press Ok. You can close the QPST Configuration window now.
6/ Open Windows Explorer and browse to "C:\Program Files\Qualcomm\QPST\bin" (or wherever you installed QPST) and launch RF_NV_Manager.exe. In RF NV Manager, Go to "Settings / Comport". You should see your COM port in the dropdown box. Select it, then press OK.
7/ Go to "File" and choose "Read from phone". RF NV Manager will read all NV items from the phone. Now if you see item #550, you will be able to alter it (see below). If you can't find it, you're gonna have to create it first. Choose "Option / Customize NV item list", then find item #550 on the left listbox and transfer it to the listbox on the right, then Save. You should see item #550 in the main listbox now.
8/ Now comes the critical step of altering the IMEI. Select item #550 and you'll see 9 boxes on the right, a "Write NV" button and an "Hex" checkbox.

First of all, check the "Hex" checkbox.
Now, you'll have to enter the IMEI in the 9 boxes in a very specific way. Check out the explanation below, copy/pasted from [FIX/TOOL] Backup/Restore/Fix IMEI Data Restore Tool Updated - Updated 9/04/2012!!!:

Quote:
The Hex values for your IMEI will consist of no more than 2 characters per a box and must match your IMEI or it will not take the values you enter.
The IMEI is also listed in a special order so you must follow this guide to ensure your IMEI is correct.
The first box will always be an 8.
The second digit in the second box will always be a.

Example if your IMEI was: 954091051099226, then the boxes would look like so:

8
9a
45
90
1
15
90
29
62
9/ You can then press "Write NV" to write the IMEI value to your phone.
10/ Once done, unplug the device, and reboot it.

That's it. Check your IMEI. Hopefully, it's been successfully recovered. If not, well, ...

Good luck!

EDIT: Please report if you successfully recovered your IMEI, and give as many details as possible i.e about your device (XT925/XT926), your ROM, your PC (physical/virtual machine type and version..., Windows version). Thanks.

@ kaktuss77: Are you able to detail how you managed to get this to work on 64-bit Windows 7?
