[zahidm]

Hi guys,
Note: I am not responsible to the brick device if you will not follow the guide step by step, this is very important to do each and every step, never think to skip any step or may be you will have a total loss, but this guide is tested and working for those who accidentally selected (format + download) while converting from X5 to 5.1 or while re-flashing.

Nokia X5 to 5.1 Plus convert Guide Link: https://forum.xda-developers.com/nokia-x5/how-to/guide-how-to-convert-nokia-x5-to-global-t3858253

Note: The only thing i want to tell you that if you followed the guide in Link above of converting Nokia X5 to 5.1 Plus, than you must have a file from step 1 that is Backup_0, and that file is the only hope to save your device Base band/IEMEI/Serial Number.
So keep in mind please always read follow step 1 and backup your current firmware that have very important partitions, and can save your bricked Nokia X5 device:
BTW I HAVE UPLOADED REQUIRE FILES FROM MY BACKUP HERE BELOW ON REQUEST BECAUSE EVERYONE MAY NOT HAVE PREVIOUS BACKUP, BECAUSE BASE BAND FILES FOR NOKIA X5 ARE SAME FOR ALL PHONES

At Special Request:
I Have added a link required files from my backup here, you can use these if you did not made the backup:


If you are using windows-10 than please follow this guide to disable drivers Signature Verification or your will be unable to connect phone in fastboot mode, you will hear sound connect/disconnect again and again if Driver signature Verification will be enabled in Win-10,
Link Guide: https://www.howtogeek.com/167723/ho...8.1-so-that-you-can-install-unsigned-drivers/


I will try my bests to make the guide as simple as i can:

So let' Start:
First of all What you need before starting the process to restore Base Band/IEMI/Serial Number
1: SP flash tool: please download latest version from this Link: https://spflashtool.com/download/
2: 7-zip: Please download 7-zip from the link: https://www.7-zip.org/download.html
3: Global Firmware: Please download (PDA-1100-0-00WW-B01_unpacked.7z) from this Link: https://tpedutw-my.sharepoint.com/:f...UN3tQ?e=wOfytH

5: Adb Platform tools : Please download from this Link: https://mega.nz/#!4rR0AAZI!N3l0FuPDrtej2GwU4VXmehBbLs2TvIlADYXcQv_Nf1Q


That's all, now please create a folder Nokia X5 in any PC disk and please copy all above files there this i am only guiding that you can open everything from one folder, not to move in multiple folders.

Now we are starting the to Restore Base Band/IEMI/Serial Number: (Follow each step carefully)

1: Extract downloaded firmware (PDA-1100-0-00WW-B01_unpacked.7z) in same Nokia X5 folder.

2: Go to Extracted folder and make a copy of " MT6771_Android_scatter.txt" separately and rename it to "proinfo_MT6771_Android_scatter.txt" (make sure do not write .txt because obviously this is .txt file.)

3: Now copy the "proinfo_MT6771_Android_scatter.txt" back to firmware folder (PDA-1100-0-00WW-B01_unpacked)

Now the very important part need to perform carefully:
3: Now right click on "proinfo_MT6771_Android_scatter.txt" and open with word pad that is normally available in windows or you can use any text editor to edit the file.
4: Once you opened the file please follow below edits in file:

Reserved and Tips:
You can also contact us at https://t.me/VictaraUni
This group is for multiple devices ROMs, Debrick Help and many more

Tip-1: To generate your Md5 Checksum you can read the serial number at your box, or back of your phone and enter manually to generate Md5 Checksum.

Tip-2: If somehow your phone is off from long time please turn it on and then power off before flashing nvram. Or may be in Windows-10 it will not be recognized

Tip-3: It's much better to use Windows-7 to do this process because installation of drivers is typical and sometimes SP Flash tool stop responding suddenly.

Okay, I'm ready to be called a complete moron, but I want to check before I give up.

Due to an unfortunate series of events, the original backup I had is gone. I do know the original IMEI and I think I know the original serial number. So, is it possible to manually change it in the backup that was made after I lost them?

Side note, where exactly is the serial number on the box, since I couldn't find it there?

You can use my backup, may be it works for you, because you need 4 important files from backup..

I will upload link of my backup files, those only required to restore baseband/imei/serial, in Post#1, i think it will work because all Nokia x5 have same baseband

Please follow each and every step strictly and all now you have to do is use your own serial number:

Thanks, I'm currently busy due to a deadline breathing down my neck, so I won't be able to try it right now. I'll be sure to report on how it goes when I do.

On a side note, the serial number is something that has confused me for years, some people use it as a synonym for IMEI, while others don't. So do I use my IMEI or do I go back to trying to find my serial which I can't actually find on the box...

I'm pretty sure it's obvious at this point that I'm not the type of person that should have messed with this, so final question. Is the serial number the last 6 digits of the IMEI, without the check digit?

(I'm really sorry if I'm being a pain)

No man, serial number is different and will be different , and starts with PDA , if you are unable to find the serial number and you know the IMEI, there are many websites can search serial number from IMEI, you can ask help.

I tried but when I try to flash nvram it fails and say the target device is locked, I tried unlocking bootloader but it also fails whenever I entered the command, initially it tells me that unlocking bootloader is not allowed so I turned OEM unlocking on from developer options but now if I enter the command it fails and say unknown command, please I don't know what else to do I can't make calls with the phone because the IMEI is missing
