That's my problem, I wanted to downgrade my tablet Via the command "Fastboot" and by mistake I copy the file to boot.img. Since then the tablet will not boot into recovery and hangs on "starting fastboot" Firmware Version 209.5.
"Fasboot devices" Works. But no "command" posssible writing.
I have bandwidth to recovery by the command "adb reboot recovery"
My tablet Works Well, I do not know for more change anything or the root.
Is there way to reinstall "Fastboot" in tablet?
My firmware is UL-K010-WW-12_10_5_11-user
