if u want use global verson rom.
use WW lk file.

but make sure u already set sku to WW

so the key is :
if u want use global rom.
1. flash to global rom.
2. change sku to WW
3. flash lk WW.

if u want use Chinese rom.
1. flash to CN rom.
2. change SKU to WW
3. flash lk CN

that it, it worked for me.

i own device with SKU ID (indonesia)

its can use global rom, or chinese rom, and can ota update without a problem.

Gan pas saya mau flash ko ada bacaan verified boot img ? Tolong dibantu gan

You can't download from link in Post#1?

Unlike previously released Qualcomm based Nokia phones, Nokia X5 uses MediaTek Helio P60 processor.
However, unlike Nokia 3, it no longer uses authentication file, this will make unbrick easier.
After you read the full guide, you should understand how to unbrick your phone.
This guide should work on both 64-bit Linux distro and Windows operating system.

And this guide is simplified than previous guide to ensure your phone will get newer updates.



What you need to have:
- MTK Smart Phone Flash Tool, which you can download from https://spflashtool.com/download/
- Android Platform Tools
- For Windows users, patched OST LA: https://drive.google.com/open?id=1n91aYT9Di6_v4F3Wjlv8TjfeLc64AcYA and MediaTek USB Port driver, which is easy to find
- Nokia X5 Chinese firmware and Global conversion firmware: https://tpedutw-my.sharepoint.com/:...dFks--5G6V4vYBGTwLw1BsthbtIuJqMUN3tQ?e=wOfytH

Part 1: DO FULL BACKUP
Because few critical partitions are included in this backup, this will ensure you can restore them.
Download "PDA-1100-0-00WW-B01_unpacked.7z" and extract it.

Open Smart Phone Flash Tool, choose the Download Agent file and Scatter File in the unpacked PDA-1100 firmware.

DO NOT USE DOWNLOAD AGENT FROM THE FLASH TOOL ITSELF!

Then pick "Readback" tab, add a category.

Double click this category, and choose the location you want to save the backup.
Use any text editor to open the scatter file, and find "userdata". You'll need the start address of userdata as the length of the full backup.

After it properly set, click "Read Back", then power off your phone and connect your phone to PC with both volume keys pressed and holded.
When you see a progress bar moving, you can release both keys and wait for the procedure complete.

Disconnect your phone when procedure completed.

Part 2: Flash PDA-1100 global firmware
Return to download tab, choose "Firmware Upgrade" in the download options, click "Download", then power off your phone and connect your phone to PC with both volume keys pressed and holded.
When you see a progress bar moving, you can release both keys and wait for the procedure complete.




Part 3: Modify SKUID and flash lk
Trigger your phone to Fastboot mode.
You can type this command then connect your powered off phone:

.\fastboot reboot-bootloader

Type this command to confirm your phone's Serial Number, in this example the serial number is PDAGAM0123456789:

PDAGAM0123456789	fastboot

Google a website to calculate the md5 checksum of the serial number, for example, the md5 checksum of PDAGAM0123456789 is bb1bfc95418f51dc906462554d71313a.

Now type following command to grant service permission:

.\fastboot --set-active=a
.\fastboot reboot-bootloader
.\fastboot oem dm-verity (your_md5_checksum)

In this example:

.\fastboot --set-active=a
.\fastboot reboot-bootloader
.\fastboot oem dm-verity bb1bfc95418f51dc906462554d71313a

Type following commands to confirm and modify SKUID. Following commands are case sensitive:

.\fastboot oem CustomerSKUID get
.\fastboot oem CustomerSKUID set 600WW
.\fastboot oem CustomerSKUID get

Type following commands to reflash stock lk and reboot:

.\fastboot flash lk_a G:\PDA-1100-0-00WW-B01_unpacked\PDA-0-1100-00WW-lk.img
.\fastboot reboot

Part 4: Install PDA-209B update manually.
Download this package, and rename it to "PDA-209B-0-00WW-B06-update.zip", place it to root directory of internal storage and dial *#*#874#*#* to update.
https://android.googleapis.com/pack.../b1ebc1be5c4b01109fc3c4dea515e8286904fad0.zip

Old ota packages:

That's it.
Is it bootloader unlockable? Still finding out.

Do you have global variant or Chinese variant of the phone .

 

[Axel_13]

Do you have global variant or Chinese variant of the phone .

Global variant.
I was actually following your guide of downgrading Nokia 5.1 plus.but mistakenly i used "DOWNLOAD AGENT" of the SP flash tool,due to which my device got bricked.
After following part 2 of this guide, i can boot it to recovery and fastboot mode.
Should i proceed to part 3?or do something else,to get my device working?
Thanks in advance!

Problems start when members ignore steps by using there own past experience.
