Default Bootloop, formated /system

Hi.

I have a problem with my Sony Xperia Tipo. I have CM10 and I downloaded rom based on it. Everything went ok, but this rom needed storage fix. I've changed file that was needed for this in Root Explorer (because some people said that doing that in CWM isn't working), so I have done that. After that, when I wanted to restart the phone the phone restarted itself. After few restarts I've seen that my phone is bootlooped. I pasted rom zip on my micro SD card with computer and a reader and I did factory reset and formated /system. After this I've seen that CWM can't read the external_sd, probably because of some problems with this before. I want to send this file through ADB, but I haven't unlocked USB debugging yet. What should I do? I have CWM, now useless ADB, unlocked bootloader and formated system ;_; Sorry for my english.
