RIP T428?

[Titoy]

I've just flashed a T428 HDMI key with Tronsmart T428 4.2.2 Finless 1.5a when ROM_Flash_Tool_137 displayed an error message during checking process.
Then I tried to restart flashing once again after erasing NAND but T428 disappeared from WinXP USB monitoring.
Since then the HDMI key is unable to be recognized by WinXP. Restart and Re-install WinXP didn't solved this issue.
When I try to start T428 on the Sony Bravia TV then the screen is desperately blank.
Using restore button doesn't help on the PC nor on the TV.

It seems that the HDMI key is dead...

Does any one of you have a brillant idea?

Hello,
Thank you for the information.
I was able to perform short circuit as mentioned in these tutorials (6-7 or 7-8 or 8-9). But unfortunately I had no result except freezing the computer... I wonder if the Key has a short cut in it.
Thank you for your help.
