iphone 3GS recovery only solution.....

,this phone came-in to the shop with a "recovery mode" only problem.

,the first thing that i do is to kick it out of recovery using tiny umbrella, result is the same.

,then i restore it using 4.1 firmware with my hosts file pointing to saurik server hoping that its shsh is saved, it came out with error 1604 (as seen from the image below), darn no saved shsh..



,then i try to restore it using 4.2.1 firmware, it came out with error 1015, and the result is still the same. hmmm...maybe this was unlocked before using the update baseband option..

,i check the logs and this is what is shows..



,so my speculation has been confirmed, the baseband has been updated to 6.15 that is why restoring to 4.2.1 ofw still gives me error.

,so to quote the dev team..

WARNING — YOU DO THIS AT YOUR OWN RISK! PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

1.There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple. You’ll be voiding your warranty in a very obvious way.

2.If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).

3.Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail). You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).


,so from the number 3 quote above, to solve the problem i need to restore to a custom 4.2.1.

,so here's what i did..

1. download the custom ipsw here.
2. open redsn0w 0.9.6b6.
3. browse to 4.2.1 ofw.
4. check on "just enter pwned DFU right now" and wait for it to finish.
5. open itunes and shift-restore with the custom 4.2.1 ipsw.
6. wait till finish and itunes will not give you any error.

,here's the screenshot of the mobile..
