I was banging my head for like a week, I tried to use a rom that was 2.17 when I was on 2.08 and I started breaking things and flashing 2.17 kernals. nedless to say it got messy. using a command prompt I tried to get into fastboot usb and relocked my phone and ran a ruu_shooter_s_sprint_wwe_2.08 exe file on my pc when it was in this state and it said I already had firmware 2,17 on unit do I want to downgrade it to2.08 whicjh I did so I could use soprint to update to 2.17 properly then go to custome rom. It always errored out, finally i found an ruu 2.17 "RUU_Shooter_S_Sprint_WWE_2.17.651.5_Radio_1.06.00.1216_NV_NV_spcs_1.42_release_233304_signed" with that file it just flashed my phone to 2.17 and I was able to unlock my phone again but with hboot1.5 s is stil on. I couldnt get clockwork mod back on it easilt but luckily teamwin has twrp 2,0 which is like clockword mod but works decent with 1.5 followed instructions and installed that then I went into it installed meanrom which had superuser rights and reinstalled titanium and used it to recovery my rom manager and used that to push clockwordmod to my phone so know Im on 217 rooted and Im loving the new rom.
