1015 is successful. Just use tinyumbrella's exit recovery to boot your phone back up.

Edit: sorry, if you went to 4.2.1 you can't do that. You'll use a different method. Which fw did you restore to?

Hi, I was trying to go to 4.2.1 but I did so many intents with no luck so I went to 4.1 and had luck thanks for your help

I see you fixed it but for anyone else in the same situation tiny umbrella has a "fix recovery" button now for when you get that 1015 error on 4.2.1.

Awesome, thanks for the heads up. Question though, for those with bb 6.15.00, can they now restore to stock 4.2.1 and exit recovery with TU?

They sure can.

Hey everyone, need some help.
Running a iphone 3gs on 4.3 trying to downgrade it and get an unlock, dont have the ssh saved in tiny umbrella. Saw a site that said to alter the c: drive any idea how I can do a downgrade. i have all ipsw files for all previous versions on my desktop. Please help!!!
Also no unlock for 4.2.1 on iphone 4 yet?

If you dont have 4.2.1 SHSH there is no way to downgrade sorry.

Nope, no unlock for iPhone 4 on 4.2.1 yet.

**goldie737** · 03-16-2011, 01:14 PM

what if i have the shsh in tiny umbrella but it belongs to my other phone can that work?

**Simon** · 03-16-2011, 01:22 PM

Nope, they are device specific.
