Help screen does not turn on after Down Grade

[Artanis]

I flashed to no2Chem 2.0 rom everything worked fine except bluetooth headset. Decided to downgrade to 2.17 cause I dont use gps as often as I thought. So I flashed last night via sd card rom loads fine, do softreset before sprint mods. screen turns on fine but if sleeps does not wake up. Tried flash via pc this morning to 2.09 same problem.

Did you install the old bootloader/unlocker/locker?
