UT1 does not boot after flashing with original firmware

[Nedo]

Hi

The UT1 is not recognized by rk batch tool or rk develop tool after flashing the original firmware from november from here:

http://ugoos.net/ugoos-brand/ugoos-ut1

Before that I have first flashed with wasser firmware and after that with the allminipc-firmware - with no problems!
Then I wanted to flash it with the firmware from the ugoos website, but after the message "firmware download started" it said "firmware download failed". The screen on the tv was blank. So I restarted the UT1 but there was again just a blank screen on tv. Trying to get into recovery-mode (switch ut1 on, connect usb to pc, switch ut1 off, press the recovery button and holding it, and switching ut1 on) does not work, the pc (both rk tools) don't recognize it.
what's the problem and what did I wrong?

regards
n.

Have you tried flashing one of the other firmware's that you previously had installed ?

thanks for your reply

as i said, the problem is that the ut1 is not recognized by the pc - so it is not possible to flash anything, in standard way (recovery mode)
is there another way to flash?

I have a UT2 and I had the same thing happen. I followed this You tube video to fix mine.

I know this is for a tablet but worked for me on my TV box.

sorry for the late response - i have been on vacation for a long time

i had contacted the ugoos support and they told me this:
if icon is grey, its mean that PC not see device or device broken in hardware
Try to connect and just wait about 10 minutes, maybe PC will see new device. It may help when old firmware and new firmware have different loaders (i don't know which loader version wasser use). If they are different sometimes after flashing device not working and exist in fail mode.
If it not help, only one way to unbrick device is: disassemble device, found nand flash and shortcut pins like this http://img513.imageshack.us/img513/6853/0kh1.jpg, and power on device. Then release pins, device will be in MASKROM mode (blue icon in batchtool).


... i had to shortcut the pins, i think it's pretty the same solution as "SLHQC" posted it
