First of all, hi everyone ! I'd like some help, if possible of course. I had a new iPhone 3GS (16 Gb, new iBoot, 3.1.2 stock) in february (just as the damn 3.1.3 FW arrived, too late to save SHSH on Cydia), and managed to jailbreak it. So as I'm using a PC computer, with Windows 7 64 bits, I decided to use blackra1n to jailbreak it (from blackra1n.com). First of all, everything was cool : the jailbreak was done 1st time, I arrived on the iPhone OS, used blacksn0w to unlock (I must unlock it, not the official provider) ... everything was fine ! Please Register or Log in to view images (I even tried to reboot, it requiered me to re-blackra1n, tethered Please Register or Log in to view images, but worked as well, 4 or 5 times to be sure). I managed to install, via Cydia, all the stuff I need ... installed Winterboard, etc. After that, it required a reboot, I did it, blackra1n as usual ... and BAM ... nothing happened ! Please Register or Log in to view imagesPlease Register or Log in to view images I must explain : - I click on 'Make it ra1n' - the Geohot image appeared on the iPhone screen, while 'running' was on the blackra1n application - blakra1n told me 'done, wait for reboot' ... my iPhone reboot ... and NOTHING, black screen ... - I waited, some mins, nothing - restart the iPhone : iTunes logo, nothing - blackra1n another time, the same And since february, my iPhone is stuck. I didn't restore it in 3.1.3 to be sure not to lose baseband. Can you help me ? Thanks a bunch, in advance !
