I did 3.1.2 OTB jailreak with blackra1n rc2.
When I tried to restore with custom fw 3.1.2 it took long time at "preparing iphone for restore" screen and then it gave me error 1604. Then I have to use itune to restore it back to 3.1.2
Am I doing anything wrong here? Is there any solution to this?
Thanks in advance for all the help and suggestions.
how do you restore custom firmware.
in itunes just shift click restore and select fw right ?.
That is correct
One more thing:
I got this custom ipsw from a friend as I don't have mac.
what i meant is did you put phone in dfu mode or recovery mode. If you did then that is not needed. no need for dfu/recovery.
I have the iphone 3gs otb with 4-5 digit serial 41, with legal att sim.
I jailbreaked with blackra1n rc2 and got to main screen on iphone.
Than I opened the itune and did shift+restore and select the file a friend sent.
It took a long time at "Preparing iphone for restore and then it gave me 1604 error."
Meantime iphone went into recovery or dfu mode and only way I can get out is to do a restore from itune.
are you sure that custom firmware is good ?
That phone (week 41) probably has a new bootrom.
I'm not sure if you can restore a custom fw to it. I think you should because once jailbroken, the phone is pwned.
I don't have anything like that to test here.
But I just tried the same thing on iphone 3G and it works (fw 3.1.2, jb with blackra1n rc2 then restore with custom fw 3.1.2)
ps: I think something may be wrong with your custom ipsw.
Take a look at your itunes updater log file. It is located in
C:\Users\<username>\AppData\Roaming\Apple Computer\iTunes\iPhone Updater Logs
