For about a month I have on the galaxy nexus rom slimkat + kernel dfk and until tonight I had not any problems, until this evening the phone has rebooted and the disaster happened, the boot animation was jerky and the phone has put more than 5 minutes to power, however going slow, and even after I have booted the phone is super slow, it's all jerky and unusable.
From recovery I tried to wipe system, but even if the message confirming correct operation, it really does not matter because if I reboot the phone loads the system, even if ever so slow and jerky.
I also tried to use the Nexus root toolkit but nothing, when I try to reflash stock hangs the command "writing system" and does not go forward ... I do not know what else to try.
I also tried using fastboot commands, but nothing changes ... not the operations are successful and the changes are not applied.
Please help me! Thank you very much!
