PLZ HELP! Tried to JB without updating ios 1st. Stuck at Silver apple
So I just got a new for me iphone 3g running 4.2.1 on it. I decided to downgrade to 3.1.3 to avoid any speed issues and for a solid unlock but soon realized that I couldn't use ultrasnow for 3.1.3 because of the baseband. Despite not wanting to use the Dev Team's new, irreversible baseband update to unlock I realized that I didn't have much of a choice and proceeded to run redsn0w...without updating the ios on my phone first!
So I went straight from 3.1.3 to 4.2.1 and instead of completing the jailbreak the screen went black for 2-3min after the "downloading jailbreak" screen and then just froze on the silver apple logo. I've retried only to get the same results over and over again and iTunes doesn't even detect the device.
Please help!!! I'm desperate for any kind of solution and while I've jailbroken a 3g once before I still consider myself a noob that's just good at reading instructions (except for in this case obviously).
I just bought this phone used but it's in perfect condition and I want to be able to use it.
Thank you to anyone who has some advice!
