Okay, so you can boot your phone right?
Let it reflash and get booted, enter the market, and download Terminal Emulator, if you don't already have it on there.
Follow these instructions:
Download this
http://www.mediafire.com/?bx14hzq5i2pq3ps. It is a ZIP file, inside it is a file called flash_image. Copy it to your SD card (the extracted file, not the archive.)
Download this file
VM670NH_recovery.img to your SD card and rename it r.img
Type those lines into Terminal Emulator one at a time. If you get any errors STOP and report back. That should re-flash your recovery. If it goes well, type "reboot recovery" in terminal emulator and it should hopefully boot into recovery, from there you can flash a ROM.
