Hello. I ran in kind of problem... I have iPhone 3gs, that needs blackra1n every time i turn it on. Problem began few days ago, when it got stuck, so i had to reset it, and when i tryed to blackra1n it, it got stuck... I tryed few more times and than it worked. That happened also next day, and i had to do blackra1n like 20 times. Now i this does not work anymore and it gets stuck everytime. Problem is because i have on cydia only files for 3.1.3 so i cannot restore it to 3.1.2 as i normaly did. I have sbsettings and SSH, but i think i turned it off :/ I have 05.11.7 modem firmware and 6.4 bootloader. What can i do?
