HTC TyTNII Broken !!!!!! HELP ME

[feizuy]

Hi, Yesterday, I changed the battery as usual (I have 2 batts and a desktop charger) to my TyTNII, and when I turned it on, it started on a mode where 4 colour lines appeared (red, green, blue and white) and at the bottom of them says the word "SERIAL".
Also, when its on this mode, I have to remove the battery to turn it off. When I turn it off and turn it on again several times (about 20 times aprox.), the Windows starts, when it starts I plug USBCable to PC but doesnt sync and when I reboot the Windows the problem happen again. I have both batteries fully charged, so its not a charge problem. I tried to reset it and also I reinstalled the ROM but nothing happened.
If someone has any suggestion please help me.
Thank you.

Its in bootloader mode. This is the screen from which you can hard reset your device or install a new rom. Dont panic. Follow this link to install HardSPL if you haven't already:

Then click on this link to learn how to flash your device with a new rom:

I recommend downloading HardSPL 3.56 at this location:

Then if you are looking for a really good rom I would suggest this one:
