The phone is rooted and safestrap installed, with a CM10 rom
I can get it into the boot selection menu with power+ vol up+vol down. If i try to go into BP tools from there and wait a bit i actually managed to get into safestrap once, where it showed a 99% charge, which couldn't be right. When trying to reboot again from safestrap, it just powered down. After reconnecting the charger again i could get it to go the the M logo again, arriving back where i started.
Any ideas on how to fix this?
