hello my father purchased a unknown chinese tablet called the uno tab from Synrgic 16gb it has 2gb of ram and ran android 4.4.2 it runs a atom Z3735F its a terrible tablet i know but recently my father said its been bricked, i wanted to go into its bootloader fastboot etc to figure if i can do anything, but to no avail i cant find anything, its stuck on a boot loop power+volume down is still a boot loop, power+volume up powers down the tablet, and it just doesnt seem like theres a way to enter recoverymode, but then i realised its a atom processor, is there another method into getting into recovery mode? or is there a way to enter its bios like a laptop, (ive tried hooking it up to a usb keyboard via micro5pin adaptor and spamming del and f2 i would love any information on how to fix this, thank you
