this device not eligible to

[mypyupi]

I have a iphone 4 with ios4.1 jailbreak already

When i try to restore my iphone to an original 4.1 ipsw or a custom ipsw, the itunes gives the following error.

"the iphone could not be restored. This device isn't eligible for the requested build."

any idea?

If you do not have 4.1 SHSHs saved then you cannot go back to official 4.1 firmware because Apple stopped signing it.

Thanks for replying.

I 'm using 4.1 in my iphone . i didn't do any update. can i install shsh now?
i can see there is a SHSH blobs available to install. should i install this one?

At the top of Cydia do you have 4.1?

If so then you need to change your hosts file to point to Saurik's server.

yes it means that you do have 4.1 blobs. Also use tinyumbrella to backup them to your pc

thx all..restoring now~~

i found a reference from another website, hope it helps other users as well

- Download the latest version of The Firmware Umbrella
- Ensure that you have Java (Oracle | Software. Hardware. Complete.) installed.
- You must also download the stock firmware of the version you would like to restore in your hard drive.
- Open the umbrella program and plug in your 3GS and click 'show shsh'.
- Click 'start TSS server'.
- Put your 3GS into DFU mode.
- Open iTunes and press shift + restore and point it to the stock firmware.
- Let iTunes do its thing.
- Once restored, stop the TSS server and exit the umbrella program.
- Use the umbrella program to save the 4.0.1 shsh if you have not already.
