Impossible to JB after 4.2.1 downgrade to 3.1.3

[mr.evo]

Hi guys.

I have two iPhones 3G that was in 4.2.1 (don't remember baseband). I donwgraded both to 3.1.3. One of them is activated but locked to a local carrier. The other one is stuck in the 'Emergency only' screen.

I tried to run redsn0w 0.9.6rc11 but I get the message 'Unable to recognize specified IPSW'. Only with the 4.2.1 firmware I get the 'IPSW succesfully identified'.

I donwloaded again the 3.1.3 firmware but I got the same 'unable' message.

I also tried with sn0wbreeze but I got the same error message.

Do you have any idea about this error message?

Thanks a lot

You need to use redsnow 0.9.4 and point it to a regular 3.1.2 firmware.
