Now the last piece of puzzle of Nokia x.2 series bootloader unlock line has been completed, thanks to the help of a member called Woke_World.
After I read his procedure, I decided to optimize the entire procedure and use my own firmware file to achieve it.
Step 1: Do full backup
(For this case please use SP Flash Tool 5.1924 or newer that can be found on spflashtool.com )
The firmware for this procedure can be downloaded here: https://www.androidfilehost.com/?fid=2188818919693749336
SHA256: D056631A8A795A06795B3A4E5F334DBF9B55C3C71269831F8E7926FA3ABA5637
Please follow the procedure in this topic to do readback: https://forum.xda-developers.com/t/...-global-nokia-5-1-plus-unbrick-guide.3858253/
For this case, you need to keep Download Agent file as the same came with SP Flash Tool, and altunlock-MT6761_Android_scatter.txt
Once readback done, please extract these images inside your backup for later use:
Code:
nvcfg.img
nvram.img
proinfo.img
protect1.img
protect2.imgStep 2: Format all + Download to flash the firmware with altunlock scatter file
Switch to Download tab, and choose format all + download to flash the entire phone with this scatter file: "altunlock-MT6761_Android_scatter.txt"
Once flash complete, disconnect the phone.
Step 3: Bootloader unlock
Press and hold volume down key and connect to PC - keep that condition for around 12 seconds then the phone will boot to Fastboot mode.
Execute these 2 commands to perform bootloader unlock:
Code:
fastboot flashing lock_critical
fastboot oem unlockLook at your phone and press volume up to confirm unlock. Once done, disconnect the phone and remove the battery, wait 5 seconds and place the battery back.
Step 4: Do readback again
Once readback done, please extract these images inside your backup for later use:
Code:
sec1.img
seccfg.imgStep 5: Format all + Download to flash the firmware with original scatter file
Switch to Download tab, and choose format all + download to flash the entire phone with the original scatter file named as "MT6761_Android_scatter.txt" - note there's no altunlock at the beginning of filename.
Once flash complete, disconnect the phone.
Step 6: Power on the phone and enable USB debugging, root the phone with MTK Easy SU
[NOTE: DO NOT INSERT ANY SIM CARDS AND YOU MUST SKIP INTERNET CONNECTION]
You can download the MTK Easy SU apk from here : https://github.com/JunioJsv/mtk-easy-su/releases/latest
And Magisk APK from here : https://github.com/topjohnwu/magisk/releases/latest
When you have both MTK Easy Su and Magisk APK installed, please enable the "Run as 64 Bits" option, and tap the hash (#) button to enable root.
Once root complete, we can now re-enable bootloader unlock and restore IMEI.
Step 7: Re-enable bootloader unlock and restore IMEI
Please copy the 7 img files to your phone's internal storage:
Code:
nvcfg.img
nvram.img
proinfo.img
protect1.img
protect2.img
sec1.img
seccfg.imgThen execute these commands on your PC:
Code:
adb shell
su
dd if=/storage/emulated/0/nvcfg.img of=/dev/block/bootdevice/by-name/nvcfg
dd if=/storage/emulated/0/nvram.img of=/dev/block/bootdevice/by-name/nvram
dd if=/storage/emulated/0/proinfo.img of=/dev/block/bootdevice/by-name/proinfo
dd if=/storage/emulated/0/protect1.img of=/dev/block/bootdevice/by-name/protect1
dd if=/storage/emulated/0/protect2.img of=/dev/block/bootdevice/by-name/protect2
dd if=/storage/emulated/0/sec1.img of=/dev/block/bootdevice/by-name/sec1
dd if=/storage/emulated/0/seccfg.img of=/dev/block/bootdevice/by-name/seccfgWhen it's done, please perform factory reset to apply the NVRAM restoration.
Please watch this video for entire procedure demonstration:
That wraps up the entire procedure of bootloader unlock, and have fun for modding this device!
