Upgrade to 4.3.1/2

[Simon]

If your hosts are already set to cydia then there is no need for tiny umbrella. Your restore will verify fine without it if that is the case.

Ok i'll report back after i've attempted this. Thank you so much again.

Ok, I made custom 4.3.1 FW on sn0wbreeze, and attempted shift+restore in itunes, and i got error 1600. Any suggestions?

Just restored to custom FW, everything seems to have gone great. BUT, my device did not reboot! Now it's stuck in DFU mode, and wont exit! Please, any advice?

^What's on the iPhone screen? It wasn't clear, did you successfully restore again after the first 1600 error?

[RIKKI123]

Yes, after the 1600 error, i succesfully restored through itunes, but it didnt reboot after that :S it stayed in DFU mode, so now the iphone has a blacked screen on DFU.

You were running the TSS server werent you? You need to save your SHSH locally first with tiny umbrella if you want to restore with the help of the TSS server.

[RIKKI123]

Oh, that makes sense i suppose, so can i still do that now ? or am i screwed? can i get a quick guide on what to do please?

[Simon]

You did (almost) everything right the first time. Just save your SHSH with tiny umbrella first this time then do what you did before.

Ok i just saved the SHSH files with tiny umbrella and went through the process, the same thing has happened... Its still in DFU mode

[Simon]

What SHSH does tiny umbrella have listed for your device?

[RIKKI123]

4.1, 4.2.1, 4.2b3 & 4.3

[Simon]

And what custom firmware are you trying to restore to?

[RIKKI123]

4.3.1 , isn't that 4.3 ?

[Simon]

Nope, they are different. Doesnt look like you have 4.3.1 SHSH so you cannot restore to it. Make a custom 4.2.1 instead.

[RIKKI123]

OH Ok at least i know the problem now, i'll try 4.2.1 now and let you know, thanks

SUCCESS!! I am now on 4.2.1, thank you to everyone who contributed with their suggestions In particular a BIG thank you to x98car

[Simon]

No prob
