Tools and information

mauronofrio's recovery twrp
usb drivers
platform tools
magisk
munchy_cool's disableecrypt tool

get your files ready, the twrp img, twrp zip, and disableecryption zip
you may rename the img file into twrp.img

unlock your blackshark bootloader, i assume you have known how.
backup everything, whatsapp chats, use sms and backup restore app to backup your sms, call logs, and wifi logins

first.
check your update in which slot. is your phone now in last update ota december ? lets see in which slot it is.
Code:
adb reboot bootloader
Code:
fastboot getvar current-slot
if the answer is B, reboot your phone, and check the system is before ota or not. boot back to fastboot, and do this :
Code:
fastboot set_active other
then reboot. check if its in latest ota update or not. just make sure, which slot has been updated to latest ota, and which slot is before update.

i assume the ota update is in slot A.
format this slot by going to recovery, this should be stock recovery, then turn off your phone.

now get to slot B, turn it on, directly to fastboot, volume down and power
Code:
fastboot set_active other
it must be in _b now. make sure its _b.

Code:
fastboot boot twrp.img
do not do anything here. do not install anything first. because we are doing a backup here. so you are now in slot B, and the twrp is in slot B.
now lets backup the slot A which has been updated to the last ota / december 5th.

backup boot image from slot A using twrp.
Code:
adb pull /dev/block/sde11 boot_a.img
Code:
adb pull /dev/block/sda8 vendor_a.img
Code:
adb pull //dev/block/sda6 system_a.img
Code:
adb pull /dev/block/sde19 custom_a.img
*remember, we cannot backup userdata image here, i dont know yet how. these files you can save just in case things are messy.

still in slot B. still in twrp
go to Wipe
Advance wipe, choose data, repair or change file system, change file system, pick ext4
back to menu, choose mount, disable and enable until you have your internal storage pop up in your pc
then put the disableforceecrypt zip, flash, then reboot.

*you will see the message pop up in your phone saying there's an internal problem with your device. its normal. this happened if you decrypt the slot.

skip skip skip, check your wifi works or not, mine works. check also your device if its ecrypted or decrypted, mine is decrypted.

in this part, we have our slot B is decrypted. reboot back to fastboot to boot twrp.img
Code:
fasboot boot twrp.img
then put twrp zip, and flash.

get back to recovery, check if its normal and your internal storage automatically pop up at your pc. it should be normal..
from twrp, get back to fastboot
Code:
fastboot set_active other
and then reboot recovery

you are now in slot A, and you are about to flash disableforceecrypt zip and the magisk zip into slot A
put the zip files to your internal storage. flash disable first, then magisk.
and reboot to system.

you will see the message pop up in your phone saying there's an internal problem with your device. its normal. this happened if you decrypt the slot.

done.
you now have slot A and slot B decypted and rooted

*Rebellion is here.

Hey, you should unlock your bootloader first

Go, READ CAREFULLY the instructions below. Also if you unlock your bootloader, your PHONE data, EVERYTHING will be WIPE OUT!!!

BACKUP EVERYTHING FIRST BEFORE DOING UNLOCK OF BOOTLOADER

I'm a bit curious here. Doing the instructions will root the phone right? Is it possible to unroot or revert back to normal state?
I'd like to root my Blackshark global, and after installing China ROM JoyUi I'd like to unroot to see if it will receive updates.

Is it possible to unroot?

It is possible, but i don't think you will receive Chinese OTA.

I see. I guess I'll not bother to root this global anymore. And as you mentioned, since light settings doesn't work, and also the upside boot logo.
I guess its not worth it for now. Anyway thanks for the answer
