Then flash 214A in firmware upgrade mode and make sure to use proper DA .

Problems start when members ignore steps by using there own past experience.
Exactly ...there are reasons to include all the steps ..so that the person flash properly .. skipping any step can brick the device.

    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://fih-firmware.hikaricalyx.com/fihsw_en.html

    Part 1: DO FULL BACKUP
    Because few critical partitions are included in this backup, this will ensure you can restore them.
    Download "PDA-114A-0-00WW-B01" 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.
    image2-1.png


    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.


    If you just want to unbrick it as Chinese firmware, double click the Location of "lk_a", and choose "PDA-0-102A-00CN-lk.img" before you "Download", or you will unable to install later OTA updates.

    Because it flashes service lk by default.

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

    Note: If you're using fastboot included in OST LA, use .\fastboot-android instead of .\fastboot
    Code:
    .\fastboot reboot-bootloader

    Type this command to confirm your phone's Serial Number, in this example the serial number is PDAGAM0123456789:
    Code:
    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:
    Code:
    .\fastboot --set-active=a
    .\fastboot reboot-bootloader
    .\fastboot oem dm-verity (your_md5_checksum)

    In this example:
    Code:
    .\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:
    Code:
    .\fastboot oem CustomerSKUID get
    .\fastboot oem CustomerSKUID set 600WW
    .\fastboot oem CustomerSKUID get

    Type following commands to reflash stock lk and reboot:
    Code:
    .\fastboot flash lk_a G:\PDA-114A-0-00WW-B01_unpacked\PDA-0-114A-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.

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

    Thank you for sharing this tutorial. But how to unlock Nokia x5 bootloader? It needs unlocked bootloader right?

    Nope, bootloader unlock is not required.
    You can just convert your phone, that's it.

    Code:
    .\fastboot oem dm-verity (your_md5_checksum)

    In this example:
    Code:
    .\fastboot oem dm-verity bb1bfc95418f51dc906462554d71313a

    Part 4: Install PDA-114A update manually.
    Download the update package "PDA-114A-0-00WW-B03-1100-0-00WW-B01-update.zip", copy it to root directory of internal storage, then dial *#*#874#*#* to update.

    hi.. i had global version Nokia 5.1 Plus, can i flash it with chinese rom ?

    Yes you can, but you need to unpack PDA-102A-0-00CN-B07.nb0 and follow the guide, but change the SKUID to 600CN instead of 600WW.
    And you need to flash a different lk file which you'll find out.

    Use this tool to unpack nb0: https://forum.xda-developers.com/android/general/nb0-unpacker-packer-tool-t3699464
