Phone won't boot and can't use adb topic

I got unlocked, S-off and changed the CID to BS_US002 and flashed the latest available nandroid backup. It worked great until I went into TWRP recovery and selected "fix permission". The phone got stuck in a boot loop. I could still access it through adb, but then I made the mistake of thinking I could fix it through doing a factory reset. BIG MISTAKE. Now I can't access it with adb anymore. I can still get into bootloader and TWRP recovery, but when I restore the nandroid backup it still doesn't get past boot.

Any help please.
