I have a 3GS on 3.1.3 BB = 5.12.***
I used Umbrella to save my shsh to my PC, then used this process to update from 3.1.3 to 4.3.5,
How to Upgrade Your iPhone 4, 3GS Without Updating the Baseband (Windows)
it worked well, but iphone was stuck in recovery mode.
It suggested I use "Recovery Fix", so I did, it said it was "Done!" that my device would complete the process, 20 minutes later, it finished.
Still stuck in "Recovery Mode" Now what do I do?
Thx in advance.
