Power on device and simplify enter in Recovery / Fastboot

[Maxximo88]

Hi Devs, I have experience in modding Android devices, and I already unlocked bootloader and tested Android and JingOS ARM on my JingPad A1. Sometimes I have some problem entering in Recovery, the process is clear but if you do not press "Power and Vol-" in the precise moment you boot System normally. So, please find a way to easily boot into recovery, for example press "Power and Vol-" untile the tablet enter in Recovery.
