I have rooted Razr with CM installed. It stopped booting few days ago - stuck on CM logo. I can seen safetrap, access it normally, but phone doesn't boot. I tried to wipe and clear everything I can from safetrap. I tried to reinstall CM (newest stable for spyder_umts), then wipe and clear everything I can. It still stucks on CM logo. I tried to install Miui instead of CM - it stucks on Miui logo. I installed CM again, went to recovery mode, did factory reset, cleared cache. Still stucks on CM logo. Is there anything left I can do? Is there any way to recover stock rom (I removed it by mistake), so I can sent phone to be repaired (I have valid warranty)?
