For those of you having trouble downgrading to the older 3.1.3 firmware or even older versions of iPhone firmware, this tutorial is for you.
This tutorial fixes the problem – This device isn’t eligible for the requested build
I walk you through adding a server IP to your host file to allow you to use the older software.
See my other video on how to downgrade from 4.0 to 3.1.3 and check out the video after the break.
Hey bro, thanks for the vid…..nice work
I’m trying to downgrade on a 3GS from OS4 to 3.1.3 but getting that exact problem…”this device isn’t eligible for the requested build” …I tried your method to revert to cydia server but i’m still getting the exact same thing. I checked terminal and the line 74……gs.apple.com is definitely saved but no joy.
Preciate the help
Can you do this for PC?
I still get the error for my 3GS, however this had worked fine for two 3G’s i had updated to 4.0. not sure what the problem is. any help?
Same here. Only 3GS suffer for this. I wonder if those numbers for Apple Servers is wrong because I saw other tutorial typed in “10.249” at the end. I tried all of them but none are working and I still have that “not eligible” sign.
Having the same issue as Thankick – Still will not let me do anything, getting that “not eligible” error using both IP addresses. Any thoughts out there anywhere on what to do???
