    Am new to the forum, if anybody could help it will be great because i have done a lot of searching without sucess.

    Ok so, i have already a jailbroken iphone4 running cydia version 4.3.3 and i want to upgrade to ios 5.01 and then jailbreak it again. My problem is that i am having a lot of errors during this process which is making me mad.

    First of all i read that you need to save your shsh using tinyumbrella just in case anything goes wrong and you went to revert back and restore your phone. i have downloaded tinyumbrella and install it but here comes my first problem, tinyumbrella can't detect my iphone. I've done some search and was told it was a java problem and i need to uninstall and re-install java which i did, but still it can't detect my phone. I just left it like that without saving my shsh.

    Then the next step is to restore my iphone to 5.0.1 using itunes, so i have downloaded the 5.01 file which i rename to .ipsw because it was in .rar, then i do the restore but i had the errorcode 3194, again doing some search and came to know that there is a problem with a host file and i need to add somekind of text using notepad to the host file and save it. Then i need to put the phone in DFU mode and then restore again with itunes.

    After doing the above step i got another error code 1602, after googling came to know that i need to uninstall itunes and re-install it which i did but no luck, then i have install a program called iREB which i read maybe a fix for the problem but then i am having another errorcode 1601.

    I thought maybe i have done something wrong so i re-did those steps 2 or 3 times but am tired of this now and always having same error code. the only thing i haven't done yet is to try it on another computer but i don't have another pc in hand now to try it. PLEASE HELP.....!!!

    No SHSH = No upgrading/downgrading to an earlier iOS-version then 5.1. You are forced to upgrade to newest iOS-version. In this case it's iOS 5.1.
