You can follow the steps in the link below but use the Bison GT boot.img file from the rom on umidigi's site. I can confirm this works.

*Remember, unlocking your bootloader will cause your phone to be erased.


Here is the short version:
In a nutshell, assuming you have your drivers setup for ADB and Fastboot...on this phone, everytime I go into bootloader mode, I have to goto device manager and set the driver manually to the google bootloader one.

Steps:

1. unlock bootloader
2. install magisk apk on phone(https://magiskmanager.com/)
3. Extract boot.img from stock rom that is installed on your device. https://community.umidigi.com/forum.php?mod=forumdisplay&fid=258
4. Copy boot.img over to your phone
5. Run magisk app on your phone, click install, click from file, locate boot.img on your phone and start. This will patch that boot.img
6. Copy patched boot.img that magisk created from your phone to your PC
7. Reboot phone into bootloader mode/fastboot (adb reboot-bootloader)
8. Flash patched boot image to boot partition: fastboot flash boot nameofpatchedboot.img
9. Reboot into phone and see if it worked.

This will get root working on Bison GT

Ah, You would use fastboot to flash it. Though, there are some steps in there I generalized. Like step 1, unlock bootloader requires a few steps and fastboot...

I'll have to go back and edit my post to get much more specific. I don't have time now, buy in a few days. Otherwise, if you find someone elses post about rooting and unlocking the older "Bison", those step should all be the same.

I think umidigi has this detailed out on their messageboard. Otherwise, just wait till I get back here to update this with all the details.

I had Magisk working with the release rom. The update today will bootloop if I install the magisk built boot.img. If I push the boot.img that came with the update then the phone will boot but no more magisk.

Did you rebuild the boot.img from within Magisk on the phone using the update boot.img...not the original release boot.img.
