Hello everyone. Im sorry if theres a post out there that relates but I've searched and have found nothing. I have a 3gs, version 4.3, baseband 5.16.01, and I think a new bootrom (sn0wbreeze said), serial starts 86114, and as far as tinyumbrella I have no shsh saved. I want to jailbreak and unlock this device. I see posts that say I can upgrade my baseband to the ipad 6.15.00 but I don't know how. I tried using redsn0w to install cydia and ipad baseband but that didnt work. redsn0w (0.9.10b6) walks me through the dfu process and then once it recognizes my device is dfu it starts a process and then just fc. I would appreciate any help.
