SONY PRS T1 Sorry! The application Home has stopped unexpectedly. Please try again.

Hello. I need help. I know this is and old reader but I hope someone here can still help me fix it.
I fear I brick my reader when trying to root it using Rootset-Mynimo-B3 from here : http://www.mediafire.com/download/g1...imo-B3Home.zip

Well, the reader reboot himself buit when it got back I have the persistent message "Sorry! The application Home has stopped unexpectedly. Please try again." and it gives me the option to force close nut when I press it it just comes back on a on. I can see the wifi icon on standby, the battery and, when I connect the reader to the PC, I also can see the usb status icon with "connect" and "disconnected" when I put the cable on or remove it.

The thing is I can't reach any other option in order to soft or hard reset the reader and I can't connect via data tranfer to the PC to restore or do anything. I tried to hard reset by doing the next page and back buttons pressing but since I can´t load the Home Screen I can't seem to do anything with the button secuence.

I really hope someone can help me. I just reacieved the reader and can't affort any other one. Thank you very much and excuse my poor english. :help:
