MK808B with Linux installed, wish to back to Android

[mac-]

Hi,

I had done backup of stock partitions. Next with use of rkflashtool under Linux I've put linux boot.img on my MK808B, unfortunetely on both kernel and recovery partitions. It worked nice with system on USB IDE Hard Drive ... for some time. Now I get ext4 errors after short time. Those are related to journal, I/O and etc. Hard drive and IDE2USB works properly because I can use it for hours without any problem with my laptop then it looks like something went wrong in MK808B.

I wish to back to Android then I will be able to give it back on service after check USB on Android ... but with flashed kernel and recovery I don't know how can I restart the device to flash mode (as I did previously by 'adb reboot bootloader')?

Hi,
You can do it by pressing the "reset" button and while you're holding it pressed, plug the OTG cable to the OTG connector on the mk808B. The other end connect to your PC's USB.
Hope it will work for you.

Thank you very much. I was able to boot MK808B into right bootloader mode to flash backuped images.
