Phone freezes at Homescreen and goes into a reboot loop topic

Samsung Galaxy S i 9000 keeps rebooting after booting up to the homescreen. I don't know why this happened as this phone is in my brother's use, he says that it started happening right after he cleared the cache from Google Chorme. The phone is on 4.1 custom rom, TAJB something running Devil Kernel. What I have tried so far; *Rebooting phone without memory card. *Wiping Delvik cache *deleted Google Chrome files from the recovery file manager. Nothing has helped so far, I believe some data in the phone has corrupted which freezes the phone a couple seconds are booting up. Any help would be appreciated.
