Thank you for taking your time to view my post and possibly helping me!

My phone is about a month old and it's a Rogers iPhone 3GS 16GB

I jailbroken it using Dev-Team's method and than unlocked it using blackra1n.

Last night, I did a complete update in Cydia, and was told to reboot the device, I did so.

After that, my iPhone will only stay on the Apple logo screen for 10-20 second, and then shuts itself off again. I tried to reboot more than 30 times and tried to connect to my mac, same story......

Is there anyway I can restore it w/o the need to see it in iTunes??

I'm so upset now.... So any input or tips would be much much appreciated~!

Thanks everyone again!

Did you update mobile substrate? That has been causing problems with people. I would suggest restoring the phone in iTunes and rejailbreaking it. Is there a reason you don't want/can't use iTunes? It is required to do a restore.

Thanks mate, pardon me I didn't describe it clearly.

My phone won't even turn on now, will only stay on the apple logo screen for a while. So essentially I can't connect it with iTunes...

any idea?

You might have an iPhone with the updated iBoot, which means you can only do a teathered jailbreak. Check to make sure. :)

Please let me know if you were able to fix it and how. I had the exact same problem. :(

There is no fix for this. For the new bootrom the jailbreak is a tethered jailbreak. It requires a computer, USB cable and copy of Blackra1n to restart or reboot every time !
