I've noticed multiple boot fails after the evasi0n 0.2 upgrade reboot from cydia. I've tried to contact evasi0n at the cydia support email but it bounced. The iPhone 5, 6.1 does eventually boot on the 4-6th try.
Do not upgrade from cydia.
It seems unstable Ignore that upgrade until an official statement is made that it is safe enough.
Restore your device and re-jailbreak but then do not upgrade from cydia.
Use the compatibility spreadsheet to install the correct tweaks
