hi, i recently adquire a generic mp4, nexxtech-p2 (

it comes whith a mini-cd which contain some games and the firmware. I don't know why, installed the new fuc** firmware, and after that, it never turn on again.
To upgrade i folow the manual's step:
1)-The player must be in POWER OFF condition;
2)-Then holding or long pressing [ESC/Return] button without release before connecting to computer
3)-Connect the player to computer with its USB (The screen of PMP will blink

4)-A portable device, for example H:\, appears in “my computer”, open it and search to find out the file “ROM_EXEC” which is the firmware of PMP, o just copy another new “ROM_EXEC” file properly for this player from the software CD or other sources and then to cover that already existed in this directory (Copy the new firmware to replace the old)
5)- Disconnect the player, upgrading finished.
After that, was imposible to access to "all" the device, only to the "firmware part" follow the previous steps, and never turn on again.
I thing that the firmware that come in the mini-cd was not from my mp4, but i can't find the original one (no backups ...

)
I try the reset buttom that it has ... but nothing change.
Info that I could recolect from the chip
S210c01
0608a02

ARM
The chip is from Sisis.
Please, help me ... it was 1 day old too young to die.
Thanks
