  1. Hi
    I have a question
    What happen if i try install this rom on an bison 2020?
    Have the same chipset,and specs

  2. Hola, tengo un Umidigi bison de 6 GB de ram,con el número de compilación:UMIDIGI_BISON.E_1_V1.0_20210408. Me pueden decir si puedo flashearlo con este firmware?

  3. Non sono sicuro se il mio Umidigi Bison GT possa essere aggiornato. Il firmware installato è: Umidigi_Bison G.T.E_V1.1_20210616_1724 pensate sipossa fare!? Grazie

  4. I have an umidigi power 3 that has mediatek p60 apu, 6150mAh battery and shipped with android 10. The new umidigi bison x10 has the same mediatek p60 apu, 6150mAh battery and shipped with android 11.

    What are your thoughts on whether or not using twrp to apply bison x10 android 11 oem rom to power 3 device as a way to get it onto android 11 would be viable or guaranteed to fail?

    In addition to wanting to move device to a11 i’d also like to get there in order to be able to experiment with a12. I’m told in other forums that once you are on android 11 you can then use android 12 asop gsi [ generic system image ] update option on project treble enabled devices to go from a11 to a12 w/o needing an a12 custom rom.
