Saving my HTC One S

Hallo,

after some failing experiments with other ROMs like CM,
I'd like to get any Android on my HTC One S now. There are no backups, because I don't need any way back to my old system.

Some information for you:
UNLOCKED
VLE PVT SHIP S-ON RL
HBOOT-2.15.0000
RADIO-1.15.50.05.29
OpenDSP-v31.1.0.45.0815
eMMC-boot
Dec 14 2012, 17:10.57:222

Team Win Recovery Project v2.8.7.1

Branding: T-Mobile (Germany)

Anyway the only claim is that my phone is useable again.

Thanks in advance :)
