    Default Backing up seczone

    Im one of those people who used geohots virginizing method right away. Now were hearing rumors that the seczone that we replaced ours with wrote zeros and could seriously screw up our phone via next update. I didnt back up my seczone so im wondering if every seczone is different and if it is what steps shall I take to be 100 sure my phone wont F**k up?

    Thanks,
    Zach

    As long as you didn't use ipsf to unlock, your rsa token should still be intact, which is what i'm guessing you are refering to. Geohot has a utility that you can use back up your token. You can find his utility on his blog a "finding jtag". Google it, i don't remember the link. And you also need the specific memory range to dump. Again, i don't remember... I saw it somewhere on iphone elite's site. Like i said, it looks like the ipsf unlock is the only unlock that messes with your rsa key so unless you uses ipsf, you should be ok. If you did use ipsf, then your rsa key is already gone and you can't get it back unless ipsf backed it up at time of unlock or you backed it up yourself before you unlocked with ipsf. I am not an expert. This is what i've read from other posts.

    Well, geohot's method used ipsf to point to his server.
    But while using ipsf, the expected error about the token appears...basically, that should mean that the RSA fingerprint isn't touched, shouldn't it?

    the rsa token isn't touched unless the phone was successfully unlocked with ipsf (which involves zeroing your unique rsa token). The revirginizing method using geohot's server and the ipsf program does not touch RSA token from what i understand

    tony604 is 100% correct. If you use geohot's weekend-in-Austin server, your RSA token at seczone+0x400 is intact. If you instead used the actual (without spoofed DNS server) IPSF unlock, then your RSA token at seczone+0x400 is gone. Well, maybe IPSF still has it, but we don't know for sure.

    I also try to run ieraser on 1.1.1 wanting to downgrade the baseband back to 3.14 and unlock it with unlock.app. but as soon as i typed ieraser and hit enter, the ssh froze and i need to restart the the terminal window. any one success on downgrading baseband in 1.1.1? I may try it again this afternoon.

    Hi,
    Thanks for the info.
    I did mine on Saturday night after reading that I will be down on Monday so I guess I was on the weekend-in-Austin. What's this "actual (without spoof DNS) ..." all about?. Why the RSA token gone?. Someone used the actual IPSF server? How? did they blindly reverse dns the domain and stick in the real IP because Geohot's is down? My God ....
