I had a failure of the phe phone, using this .sbf:[ http://goo.gl/NPB7Z] The flashing worked fine, but I lost use of the phone, text was dead, and my number changed to 000 000 6778! I had to perform the dreaded *22898 and re-flash BACK to the original .621. Now I have to delete the same garbage I dumped the first time I took the phone from stock to root. I find I was 'saved' by TB, but not happy tobe back with .621 .sbf. I wil be daring and redo this again soon, I now know this flash was not a workable solution. Just wanted to inform people about the potential troubles.
