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...

Help me

Hello sir, I have done the steps you gave and all the processes were successful, but after I checked the IMEI and SV the results were still unknown The process that I have done:
1.The steps you conveyed from step number 1 to step number 7 I have done correctly (but I did this using another firmware not from the firmware that you attached)
2. Entering step number 7 to step number 7.5, in this process I have entered a copy of nvram.img and elabel.img into the adb-platform-tool folder, but in the process of writing the command prompt I entered the command you demonstrated in your tutorial (fastboot oem dm-verity 85BC0D743F935BA9078DCB290FAD2194), but the process still works
3. The "Frimware upgrade" process is also successful, but after restarting the imei and sv devices are still unknown Is the process of writing the initial command at my command prompt wrong? (sorry because I don't understand about md5)
Do you have to use the firmware that you attached and can't use other nokia x5 firmware? Please correct my mistakes, I wish you all the success of your career
Sorry and thank you very much ??

The problem is you have to calculate your md5 chack sum, by your phone detail, that's why you have no IMEI restored, ROM you can use any..
The checksum i mentioned here is Random by using a random serial number

I have checked the serial number and the device shows 0123456789ABCDEF
Can the serial number change after the previous flash? Or do you think my serial number is valid?
I have calculated the serial number and performed the steps of typing the command prompt with the serial number checksum but the results are still the same

Flashback about this device: the owner once submitted a downgrade request from android 10 back to 9 to another technician but the device was bricked and the technician had not backed up the rom before flashing, so here I was backing up files after unbricking.
Could my backup file be the cause of the problem?

I'm sorry I asked a complicated question ? thank you very much

Your backup files can't be used otherwise you will have same serial number and IMEI on 2 devices that is an illegal act, in my country, i don't know about your country.
If you have backup_0 for this device i can help to solve online

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

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:

- partition_index: SYS11
partition_name: protect2
file_name: protect2.img
is_download: true

After edit just save file by pressing ctrl+s, and close the file

5: Now go the the Backup_0 file that you saved earlier via "Readback" process in SP Flash Tool.
5.1: Right Click on file and open with 7-zip and you will see your backed up files in 7-zip.
5.2: Now press "ctrl" on your pc keyboard and select
"proinfo.img" "nvcfg.img" "nvram.img" "protect1.img" "protect2.img" "elabel.img"
5.3: Now right click on selected files and copy to extracted formware where you edited the scatter file.

6: Now open SP Flash tool and load " proinfo_MT6771_Android_scatter"
6.1: In SP Flash tool uploaded list scroll down to "Ik_a" partition and click on the loded file, change the file to "Ik_service.img"
6.2: Now Un-check all files in loaded list and just check "proinfo, nvcfg, protect1, protect2, and lk"
6.3 Now at SP flash tool select "Download only" and press download button to start. (make sure again you selected download only)
6.4: Now turn off you device and press "volume up and volume down" together and connect your device,

7.1 : "fastboot oem dm-verity 85BC0D743F935BA9078DCB290FAD2194" (This is Random md5 you have to calculate by Md5 tool as you downloaded above)
7.3: "fastboot flash nvram nvram.img"
7.4: "fastboot flash elabel elabel.img"
7.5: "fastboot oem HALT"
Never write "fastboot reboot", diconnect cable and long press power button to reboot phone.

Hello sir, I have calculated my serial number but when writing the command "fastboot oem dm-vertify (code md5 check)" I got the result "(bootloader) PID NULL, status not change"

Is my rom backup file having errors?

Thank you very much ?

I have two questions
1: You are using same device backup_0 or another device
2: Did you tried attached firmware also as it is for 5.1 Plus, and can you use 5.1 plus except X5 Chinese OS?

I am using the same backup_0 device, I am using 5.1 global pie firmware and that I can use.

Do I have a problem with extracting backup_0?

    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
