I'm experiencing the same problem. I have retail french GSM version. I installed, some time ago, the safestrap (work everything except install roms), then unistalled and install boostrap v2 and I always get stuck in motorola logo when try to enter in bootstrap recovery mode.
Also i tried a full flash with RDS (english (EN.EU) and french (EN.FR), 2.3.5 and 2.3.6) and nothing works, wipping mobile, sd-card... Just now I just tried to delete some files in the "/preinstall/app" directory and nothing... What can I do for give you more info? There is some log file that I can post?
