HELP: 4.1 JB update to 4.2.1 ?
I've got a JB iPhone 4 @ 4.1 and I'm wanting to go to 4.2.1 ever since the DST change kicked in. Stupid bug...
Internet searches show me plenty of people going to 4.2.1 but that was when it was the latest from Apple.
I've tried several methods (each with a small variation) utilizing TinyUmbrella, SHIFT+Restore & select 4.2.1 IPSW (from Apple and one Custom). It always ends with an error message and stuck in Recovery mode from which TU won't kick it out of. Thankfully I'm able to Restore to 4.1 and my latest backup each time.
Also, SHSHs are saved with TU. It says it has them for 4.2.1 which I presumed would allow me to update but alas... no-go.
Suggestions or just wait for untethered 4.3?
