Iphone 3g: 3.1.3 bb 06.15 advice
It's a long story, but I'm CURRENTLY (after everything listed below happened) on 3.1.3 on my 3g iphone, and i unfortunately applied the ipad bb 06.15.
I followed these instructions: How to Prepare your iPhone 4.2.1 for Unlock using RedSn0w and they worked fine. I believe I was running 4.0.1 with the ipad bb 06.15 at that point. So I successfully completed the above walkthrough with 4.0.1 on my iphone.
I then, stupidly tried to update to 4.2.1 using itunes. I didn't know better at the time.
I was then stuck in recovery mode and itunes wouldnt restore it because of error 1015, obviously. This was easily fixed by using tinyumbrella and I simply kicked it out of recovery mode and it instantly worked. Apparently it sent me back to 3.1.3, leaving my baseband unchanged and it remains this way, as I stated in the first paragraph.
My phone was successfully running this, until I ran the latest redsn0w and pointed it at 4.1.2 ipsw and tried to jailbreak it again. It stopped at the Apple logo after redsn0w had done it magic and I can't get it to boot up. It goes to recovery mode, but when I try to boot it gets stuck on the logo.**
**It's not stopping at the logo anymore, it goes back to recovery mode and gets stuck there. Tinyumbrella won't kick it out this time.
Any advice would be greatly appreciated. I haven't tried much yet, so even a list of things that won't work would be helpful. Thank you all so much in advance.
