I couldn't find folks mentioning my charger on this forum so I wanted to share my experience.
The charger looks very much like GT Power A6-10 or Turnigy A-6-10, so I decided to try cheali-charger firmware for one of them without modifications and it doesn't work (so far), the charger turns on, displays the firmware version and then stops at "eeprom reset:15" screen. The keyboard doesn't seem to respond.
Also I think the Turnigy A-6-10 cheali firmware burned the backlight on my screen, it went on bright for a brief period of time and then never turned back again.
I hope the problem is as simple as pin assignment for the keyboard or something trivial like that, but I'll have to de-solder the screen.
Thank you.
Below are some pictures of the inside of Thunder T610, the screen is soldered in so the most interesting parts are not visible.
