GT-King firmware：914P0

Is it possible to downgrade the firmware to 913P0? My GTKing (SN: SB9XH0KG10126 purchased 03Nov2020) worked for a couple of weeks and then suddenly went into boot loop. Right now it has 914P0 installed, it's still in boot loop, and won't let me downgrade to 913P0. Please help!

Hi, i have a problem with connection of Xbox bluetooth controller, gt king find him, but connection isnt possible. On others mobile with android the controller function without problem and quickly... why on 914P0 no??? Please help, thx
