[Android Stick & Console Computers General] z80pio:
I need help with my T428 bricked situation. I wanted to put linux on it and followed this runtimerec | how-to-install-and-hack-linux-on-t428-or-mk802-iv-mini-pcs

but i only got hold of rkdevtool may be the only difference. After running the update through this tool, my t428 does not start, hdmi goes blank, only the red led lights.. It doesnt go into loader mode with the recovery button pressed during start.

many research and tries didnt help. finally came to know about maskrom and tried shorting pins. Though the device goes to maskrom mode, i am unable to have a successful restart (even with the stock rom). I am pasting the rkbatchtool's output (restore and upgrade, tried both) below. Please help.
