[Xperia SP Q&A, Help & Troubleshooting] mark2410:
so, i have eher my sisters old SP and all was going fine. then suddenly it wasnt. i realy dont know what went wrong.

right now the thing ip you try to power it up it flashes "Sony" on the screen then seems to keel over. it starts with the red led showing. if i plug the thing in it fires up the green led for a little while and i seem to be able to access it via "flashtools" for a min or so and start to write a reflash however it then seems to reboot and start with the red led again. it sits like that for a min or two then reboots again and gives the green led where "flashtools" can see the phone again.

i left it to charge over night to see if it was a battery issue but it doesnt seem to be. im running out of ideas can anyone please help, hopefully to make it stay green long enough to flash the whole rom.
