Thread: upgrading question

    Default upgrading question

    Uploaded with

    Hi guys, I'm currently using an jailbroken iPhone 4 with a 4.0 firmware.

    I would like to upgrade my firmware to 4.2.1 , I have saved my shsh on 4.0 once only a long time ago.

    does the green firmware numbers mean i can upgrade to those firmwares?

    Yes, but before you do anything download tinyumbrella & save your shsh thru there first. It's easier than using cydias in my opinion

    Yes, you can restore to any firmware with the shsh blobs you have in Green. Go with IOS 4.3.3 for the latest IOS version with untethered jailbreak.

    what i did was
    1.) download iPhone3,1_4.3.3_8J2_Restore.ipsw
    2.) shift click restore on itunes to the above firmware
    3.) while restoring halfway it gave me the itunes error 3194
    4.) tried changing my host file to # but still didn't work.
    5.) use ifaith to create a custom 4.0 ipsw file and restored the phone back to 4.0 again.

    not sure where i go wrong, or should i restore using a custom 4.3.3 firmware then jailbreak from there using redsn0w?

    also if i managed to upgrade to 4.3.3 will i be able to do a "restore from back" to get back my contacts emails sms and settings?
