Hi CafeKampuchia, I followed your procedure from rooting with S-ON and got rooted. I currently have rooted 2.3.3 Android version. MARVEL PVT SHIP S-ON RL HBOOT-1.08.0099 MICROP-0451 RADIO-7.53.39.03M NOV 28 2011, 19:09:21 I followed the above steps and tried both 1 and 2, and couldnt update my HBOOT to European HBOOT Version of 1.09. I dont wanna try step no 3, as I feel it might brick my phone since HBOOT didnt accept my update from PG76IMG.zip and gave me an error unlike the last time when I was able to update my HBOOT without any hassle during my rooting procedure. I was wondering since I am already rooted and hence has the ability to flash any ROM suitable for my device using CWM Recovery, can I install HTC European Marvel stock Rom with Android 2.3.5 without updating my HBOOT ? And if I can, can you please tell me the procedure.Thanks in advance !
