How to fix some mysterious problems.

I'm on Mac OS 10.6 (but also have access to a Mac with 10.7) trying to upgrade my iPhone 4 with iOS 5.0.1 to iOS 6.1 and preserve the baseband (4.10.01) so that I can continue to use my Gevey SIM unlock (or use another unlock method that may be restricted to certain basebands).

I am running into errors trying to upgrade to iOS 6.1 using Redsn0w 0.9.15b3 .

Here are the steps I took:

  1. Downloaded iPhone3,1_6.1_10B144_Restore.ipsw from downloads page
  2. From Redsn0w, clicked "Extras" > "Even more" > "Restore". Clicked "IPSW" and selected the ipsw file mentioned in the previous step.
  3. On "Prevent baseband update?" dialog , clicked "Yes"
  4. Entered DFU mode as prompted in Redsn0w
  5. Got an error message "No remote blobs found | Couldn't find 6.1 (10B144) blobs for this device on the Apple or Cydia servers. Please click OK to browse for any you might have saved locally. TIP: You can mass submit all your local blobs to Cydia using the Extras->Blobs->Submit button

So I then uploaded my local SHSH blob of my current iOS 5.0.1 (which I saved using TinyUmbrella) to Cydia in Redsn0w as per the instructions, using "Extras" > "SHSH Blobs" > "Submit" and repeated the above process, but I got the same error message.

How can I get around this error and upgrade to iOS 6.1 while preserving the baseband?

Redsn0w rerestore function does work past 6.0. Use iFaith to fetch blobs to know which iOS version you have shsh saved in cydia, then stitch it to the corresponding ipsw version, do pwned dfu using ireb and shift+restore in iTunes. iFaith works on = or < than 6.1.3. If you currently have iTunes 11.1, you also need to downgrade iTunes by uninstalling iTunes and all components and installing iTunes 11.05.

EDIT: reread your question, afaik gevey for iP4 does not work on iOS6 and 7. You are stuck on iOS5 if you want to continue using gevey.

@justinred Thanks. I just updated the question to clarify: I'm using Mac OS 10.6 (but also have access to a Mac with 10.7). Looks as though iFaith is Windows only. I read about redsn0w supporting at least a tethered jailbreak for iOS 6...

@justinred also, I've seen mixed information about whether the Gevey sim unlock will work on iOS 6. if evasi0n will do the trick, then I'd be happy with that. I'm on baseband 4.10.01

As already stated Redsn0w restore works only up to iOS 5.1.1.

For preserving baseband and upgrading to iOS 6.1, i.e., custom restore, provided you have valid SHSH saved in iFaith server (iOS 6.x.x SHSH saved in Cydia are partial and not good for a restore), only tool is iFaith or Sn0wbreeze. Both work on Windows. Need to borrow windows machine.

Gevey is know to work at iOS 6. But sim interposers are not supported here on this blog. You need to get in touch with applenberry. AFAIK it is a discontinued product for iPhone 4. There are other sim interposers for these you need to do research.

Unlock from carrier is recommended method for unlocking iPhones. If you post your carrier someone may be able to help further.

@Tilerone thank you pointing out. I edited my response accordingly. I interpreted from this. Where there is mention of questionable legality of Gevey. Others being reffered to as clones.

No amount of editing of your OP is going to change answers for unlocking. If you post your carrier, someone may be able to help you.
