    if ziphone can't unlock a 4.6bl phone on 04.03 firmware.... does it downgrade to 04.02 before perfoming the unlock? if it does... does it show 04.02 in the settings>about menu?

    Poe408: Correct.

    pbmaster93: because AnySIM are designed for 3.9BL and patch the baseband rather than doing an IPSF-style unlock. The 4.02 unlock for 4.6 BL is an IPSF one.

    Thanks but I thought that the unlock geo did was just use an exploit in the bootloader to flash a 4.02 bb patched with anysim 1.2u. I'm bot to technical about this stuff but if the exploit let's you flash a bb without signature then thworatically couldn't geo just flash a 4.03 bb with the anysim 1.3 patch already in it.

    Ps. Just thinking here but it fouls be a posibilty and sorry for the spelling but I'm typing from my new iPhone

    1)“The first exploit I found, at around 4 AM last night, was the -0x20000 exploit. Just like the -0x400 exploit, but -0x20000”

    2)“The explict addresses 0xA03D0000-0xA03F0000 will always erase. This exploit relied on two things, the secaddrs are copied before the secpack is validated(stupid), and the erase command extends the range to whatever is in the secpack. So I tell it to erase 0xA03D0000-0xA03F0000, the erase command sees 0xA03C0000 to 0xA03F0000 in the secpack; BOOM secpack erased.”

    3)“The third minor concern was the full range check of 1.1.3. So use 1.1.2 This allows full unsigned code execution, it is a relatively simple matter of patching the bootloader to skip the range check. And while you are at it, patch the bootloader to validate all tokens. IPSF style unlock w/o touching the seczone.”


    i like this thread - reading above comment from geohot's blog

    - BL4.6/OTB1.1.2/BB 02.13 gets an ipsf-style unlock ? right ? sure ? very sure? is the 3rd comment reality or aspiration about modded bootloader ? was he thinking about 4.6 GEOMOD already just to make it work on 1.1.3 also ?
    - whatever he means by a full range check, something didn't work well on 1.1.3 so he had to use 1.1.2 - what 1.1.2, the OS are the baseband ...
    - did he or didn't he use a patched bootloader, was he just talking about future possibilities/aspirations (gbootloader 4.6_GEOMOD)

    or if geohot found the trick to make an Anysimed BBand work with BL4.6+4.02.13 baseband, does he really talk about a range check in the 4.03.13 baseband (damn Apple) ?

    sorry for being long and analytic, still if you see a clear response anywhere just point and clear me please

    You are correct gunlock is an ignore MNC patch like AnySIM 1.1+ and not an IPSF token-erase type.

    I'm pretty certain the IPSF RSA-hack was well patched in BL4.6. If you are referring to gunlock, it's an ignore-MNC patch like the recent AnySIMs.

    then why doesn't geo do the same thing but with the 1.1.3 bb??
