i got 4s running ios5.0.1 bb 1.0.3 that i have never updated before. i use Gevey ultr s sim(CDMA)to internationaly unlock it (since im not in stats anymore i was origanly locked to Verizon.
i have my shsh saved on cydia for 5.0.1,5.1.1,6.0.1 (some how although i have never upgraded before..)
now im trying to upgrade to 5.1.1 to cuz lots of apps demand so nowdays, so i tried using
redsn0w 0.9.15b3 , and used every single option in it trying to upgrade all failed.
even restore button i downloaded ipsw for 5.0.1 from apple and tried to use it to upgrade to 5.1 but it always fails telling me "probably the ipsw is not the one already installed"
so how can i fix that ?
also when i upgrade i understand baseband will change. question is to wt version ? should i do it ? or better stay safe ?
On my 3rd trial, i tried local shsh insteed of remote, it gave me diff error: It seems the APTicket flashed on the device cannot be reused for this hack.
If the current firmware was installed at the factory,its APTicket contain the wrong data for this to work.
Does this means no upgrade for me :( ??
Please check the FAQ before asking questions like these. HERE Scroll to where it says iPhone 4S. Are you positive it's a 4S cause you can't downgrade a 4S and you said you have 6.0.1 blobs? Something's wrong. You must verify that Gevey will work on the new baseband once it updates.
