I've been trying for almost a month to build a working TWRP for my Umidigi Bison with no luck. I've used several different methods.
I used the auto TWRP Device Tree builder and compiled from that. No success.
I used this TWRP guide https://gist.github.com/rokibhasansagar/...ac73ef79a5. No success.
I have also used the TWRP Mediatek Auto Porter here on this forum. No success.
Any assistance with getting this working would be greatly appreciated.
Let me know what if any data I might need to provide to get this thing going.
