Hello,
I have a iPhone 3GS 16GB from week 22 2009, and wonder which firmware I can update to then JB. I tried to upgrade from 3.1.3 to 6.1.2 but it didnt Allow. I made then an update in iTunes which told me the newest firmware for my iDevice is 4.2.

I have seen that other people can have up to 6.1.3 firmware on this device, how come it dosent allow me?

Ive even tried to download 6.1.2 ispw and run it through RedSn0w, still same problem, it would not accept my iDevice?

thank you so much

I was aware the old bootrom 3GS doesn't require any shsh blobs. However, the newer bootrom 3GS requires shsh blobs to restore to an unsigned firmware.

Your iOS 6.x shsh blobs may be invalid since you did not manually save them. You should still have iOS 5.1.1 shsh blobs that you can restore to. Download the latest version of iFaith and check the shsh blobs cydia has for you

I wouldn't recommend a 6.1.3 tethered jailbreak. If he has 5.1.1 shsh blobs, that would be better
 
If you phone has the oldbootrom you can untether jailbreak on 6.1.3
Otherwise it will be a tether jailbreak on 6.1.3

If you have blobs for 6.1.2 you can restore to that an untether jailbreak.

Is your phone currently jailbroken, if yes, Cydia might have 6.1.2 SHSH/blobs but you need to verify with iFaith if they are complete.

If not jailbroken before and don't have SHSH's save manually you can't restore to 6.1.2

Incorrect. Old bootrom only means untether JB. SHSH is another thing.

This.

Old bootrom 3GS cannot downgrade to unsigned firmware without SHSH blobs. If it could then I would have downgraded my 3GS back to iOS 5. :mad:

Oh, thanks for the correction

I never tried the downgrade as it was problematic. I would love to downgrade my old bootrom iTouch 2G to 3.1.2 but only learned about shsh blobs when 4.0 came out :(
 
updated to 4.2 from 3.1.3

Like i wrote in the beginning when I asked the iPhone 3GS earlie 2009 was with 3.1.3 iTunes said there is a new version for the device 4.2!

I have updated the device to 4.2, but now it need an activation through a simcard without pincode.

So, what can I do to update it further to 6.1.2 where Evasion JB works perfectly?

kind regards.


OH I SEE ITS A IPHONE 3G??? HOW CAN I SEE THE DIFFERENCE BETWEEN IPHONE 3G AND 3GS???

Look at the model number at the back of your phone: http://support.apple.com/kb/ht3939

You probably need to make a custom firmware with hacktivation included. You might need to put your device into pwned DFU mode too

sn0wbreeze might work for you
