    Default How to leave the "IPSF" slavery.

    i've just tested this on a friend's iPhone, was 1.1.1 unlocked with IPSF and accidentaly "bricked" by an unwanted 1.1.2 update via iTunes.

    1 - put the iPhone in DFU
    2 - restore with 1.0.2
    3 - "ierase" the baseband with the 1.1.2 secpack, then downgrade the modem firmware to 1.0.2
    4 - put the iPhone in DFU once more
    4 - upgrade to 1.1.1 with iTunes and simply jailbreak/activate via jailbreakme
    5 - unlock with AnySIM 1.1.1 / 1.1p

    that's all. no need anymore to wait for IPSF releases.

    did during syncing his iphone, the 1.1.2 file just appeared on his hard drive and then he accidentally had his elbow on the option/shift button and was hypnotized by the update button into pressing it!??

    how unfortunate.. ieieie

    Umm.. anyways, downgrading modem firmware of an IPSF unlocked phone will not relock it.. thus you wouldnt need to use Anysim 1.1.1 (step 5), you cant leave ipsf (with the current "in the wild" tools)

    that was exactly my thinking, but with those such of downgrade, seems that IPSF automagically disappear... maybe the rewriting of the 1.1.2 and the back conversion to 1.0.2 do the magic?

    when in 1.0.2 i can't state if the phone was still unlocked (AT&T SIM was in the slot), but in 1.1.1 the phone was locked back.

    Yes and no. It's true that there is no one-click tool to "leave IPSF" per se but those folks that are lucky enough to have a IPSF cache file can use a combination of available tools and manual edits to recover the original token that gets zeroed out by IPSF and thus rebuild the original seczone and revirginize. Details are available at the iphone-elite IPSFCache Wiki page.

    I'ts more easy to do nor to explain:

    the steps are clear, the only differences is that BEFORE to connect iPhone to iTunes it must be put in DFU mode (10 seconds home+wake and ten second home, black screen).

    In DFU the restoring / upgrading process seems to take quite more time, maybe because iTunes rewrote really EVERYTHING on the iPhone.

    btw, i've just retried with another iPhone (not IPSFed but unlocked via AnySIM), experiencing a NO-WIFI / NO CARRIER issue: completely restored.

    Honestly I wouldn't waste your time. Either way you're phone is currently unlocked and working, so why fuck with it?

    AnySIM is free and reversible, IPSF not. You can sit down and wait for IPSF releases (if there will be any and will be FREE upgrade) or clean up your phone and choose whatever you like better.. no? Freedom of CHOICE.

    btw: have you ever tried to claim a warranty repair with an unlocked phone?

    I highly doubt that the process described by iRev rebuilds the damaged seczone, intentionally corrupted by IPSF. More likely the proces of downgrading the baseband and firmware to 1.02 and then to 1.1.1 but the phone back into a state that was compatible with the IPSF patch.

    could be, but at the end of the process the phone seems correctly unlocked (correct IMEI and correct messaged whit the non-AT&T SIM), and could be correctly unlocked by anySIM 1.1.

    and also, with a downgrade + virginize looks like OOTB.
