u were the first. nice!
This zip has two sbfs. One of them is the recovery sbf and the other is the FRG22D sbf. You dont need that one but it's there anyway. The update.zip is the one from motocache1 which you dont need for this procedure either. Just download rsdlite, reflash your recovery using the "MC1_A855_1282081087_Recovery-Only_SPRecovery_0.99.3b" file flash the rom of your choice.
