Symptoms & Preventative Measures

When a Apple Computer Company iPhone 3GS needs a 3G Rollback from iOS4

Not All iPhone 3GS are the same. Please check your software version to determine eligibility.

The 3GS iPhone cannot necessarily be rolled back to older software versions, nor updated for that matter. In layman terms, Apple intoduced a secure hash File (think of it a s a password) your iPhone has, like a serial number, that is verified against an Apple Server with another hash (password) that generates an approval code for the iPhone to proceed with a restore. This was implemented into the iPhoen 3GS upon initial release, and into 3G iPhones at the release of iOS4.0, as well as the iPhone 4.

If you are to get an iPhone 3GS Rolled back, you will need to know this information available when you call us at 417-268-5211 :

  • Determining your Current iOS (Current Operating System) is important. View this at SETTINGS > GERNERAL > ABOUT > "Version"
  • The Software Model Number also matters. View this at SETTINGS > GERNERAL > ABOUT > "Model"
  • The Modem (Baseband) Firmware Version. View this at SETTINGS > GERNERAL > ABOUT > "Modem Firmware"
  • SHSHs** on file locally (on your personal computer through SHSH storage programs) or remotely via Saurik's SHSH Cache Server
** If you do not have a SHSH on file for the particular operating system, you CANNOT restore to such software... As of yet (We do have someone working on a workaround to enable this without such SHSH). Essentially, this code that Apple stores on it's server is specific to your iPhone 3GS, and yours alone. It cannot be generated (atleast not that we know of), thus we have a way to store the password sent by apple, called the SHSH. Saurik has a way of storing them in an online database (If you selected "Yes, Make my life easier!") available to store your SHSH only while those hash files are available for the particular software version. If Apple is no longer supporting the iPhone Software for your version of device, it is TOO LATE to get this hash (password) from Apple's server.

Symptoms of installaing iOS4 (or later) on a iPhone 3GS

Those that have installed the iOS4 (or later) may the operating system to be incredibly slow and frustrating to use. Symptoms include (but not limited to) text messages taking forever to send, slow boot times, long delays in installing or simply exiting applications, and slow internet usage. This 'rollback' will restore an older, yet faster, version of the software. Please refer to the chart below to see what is available for you iPhone.

Can a 3GS be rolled back the same way?

No. Apple has made rollbacks on the 3GS significantly more difficult. Only certain iPhone 3GS phones can be rolled back, usually those that have been jailbroken in the past and have an SHSH on file for the rollback software. Same with the iPhone 4.

Is there any warranty on the software?

No. The software is original Apple Software. Any liabilities for the software must be taken up with Apple INC. Ensure that you backup your iPhone before using this service, and synchronize your contacts with Outlook or other contact management software, as iOS4 backups are not reverse compatible with older operating systems. Your iPhone WILL be wiped clean with this repair.
