After the last update on RR 2207, i have a bootloop. I try a factory reset and a lot of other firmware but i have alway a bootloop...
So i do a flyme restore and i use the firmware on http://xep.8800.org/pro5/flashtool/F...prd_stable.rar. and the phone is alive! YES
But the problem, it's the 4.5.4D and not a 4.5.4a or 4.5.4i/g, so i can't upgrade to a firmware with a BL unlocked... i can't upgrade to anything...

I try Kingroot, change the id region, try all update firmware, TestPc tool but i have a "token sign failled"...

I was found a thread on htcmania but there are no solution...

Help me please i don't have more idea...
