I have the same problem.

I had extensively modded with N9qt, then suddenly my n9 rebooted, and that was it, I could not reboot.

I had an open-kernel, so reflashred ernel. No effect

Reflashed rootfs, 10 times, no effect

Reflashed rootfs, erased user data and flashed emmc, 10 times, no effect

tried different rootfs. no effect.

The n9 reboots, sometimes to the start of the first tour, then just reboots again.

RD mode seems faulty as well. No wifi, cannot run most applications, so it is not even useful as it is. Disabling rd mode means continuous reboots.


Am going crazy, right now is not the best tiem to change phones...


EDIT: Wouldn't flashing so many times remove any mistakes I made? n9qtweaks is not working in rd mode, so cannot do a restore. And am not sure what caused the initial problem
