Discuss [All Firmware] Should we go from 4.6 to 3.9??? at the iPhone "2G" (Rev. 1) - Hackint0sh.org; don't forget. 4.6 is required at the moment to attempt to use 4.6_geomod bootloader. he ...
don't forget. 4.6 is required at the moment to attempt to use 4.6_geomod bootloader. he attempted to load it on a 3.9 and it bricked. so 4.6 might be required to be able to jump to the new possible custom bootloader.
im waiting, why? cuz it works, its unlocked, and i can make phone calls/text people i needa get ahold of. when there is an amazing break through i will make my move. i don't wanna keep jumping around with my phone like its literally a toy or else ill break it like half the people on here lol.
originally OTB 1.1.2 iPhone 4.6BL
now blackra1n'd 3.1.2
Complete agree, I'm in the same situation.

Just wait some time....we will see the better option in a few weeks for sure
I agree with you as long as the seczone and the locks are concerned, as these things are encrypted individuallly on a per phone basis. This makes a true unlock so difficult, because we would need the master key to decrypt/re-encrypt the seczone after an unlock.

As BL3.9 is older than BL4.6, it probably will have similar flaws like BL4.6 - because otherwise these holes would have been closed in BL4.6. Both bootloaders, as long as they are unmodified, have a known CRC, so it would be very easy for Apple to find out that a modified or 3rd-party bootloader has been installed on the phone. Whereas i consider it quite safe to stay with BL4.6 or downgrade to BL3.9, i think a modified one like Geo's loader will produce a much higher risk of your phone being rendered useless by a new firmware revision.
As many have concluded it's a matter of personal choice.
Some like to be on the "perfect solution" and are for running 1.1.3 with the 04.03.13G baseband.
Some like to play it safe, and wait. You can perfectly wait for any progress in GeoHot's custom bootloader either at 1.1.2 or at 1.1.3 with baseband 04.02.13G. I'm still to seen any major advantage in 1.1.3.
Also, I've unlocked several 4.6BL phones to 1.1.3 with 04.02.13G and they all work 100% fine, except for Google Locate.
If experience and history serves for anything, the original A17 unlock, that was the basis for anySIM 1.0 should serve to remind us that we must always look for solutions and hacks that can be reversed. It was a terrible time when people upgrade to 1.1.1 by mistake and bricked their phones. It took GeoHot quite sometime to release the first revirginizer (fakeIPSF method) allowing the recovery of bricked phones and 1.0.2 to upgrade to 1.1.1. For quite some time anySIM 1.0 effects were not not reversible.
So if there is no tangible gain in downgrading and there are perfectly working solutions, why anyone would give up the option of using the next generation unlocking scheme (that is whay 4.6_GEOMOD will be). Those thay stay at 4.6 will not give up any of the options. On the other hand, those that downgrade will probably give up the change to use the new custom BL, and will gain only the ability to run Google Locate.
Again, it's a personal choice.
One nice feature of BL 4.6_GEOMOD is that one will always be able to revert back to 4.6 or 3.9 or even to a new BL that apples may release (if there are advantages there).

I don't think a 3.9 downgrade is irreversible at this time... consider this:
1) Ienew erased parts of the BB FW, so that the A17 pull-up would fool the bootrom into thinking the "bootrom locations" were blank.
2) Iunew, with the A17 testpoint, fooled the bootrom into flashing a new BL.
3) Geohot states that in Gbootloader he has protections to prevent a BL without the bootrom locations blank from being uploaded.
4) THEREFORE, if my logic is correct, downgraded BL39 phones now have the bootrom locations blank and can simply run iunew without the testpoint with the 4.6 NOR.
5) If my logic is correct, anyone with a downgraded BL39 can do this too. In native BL3.9 phone this would not work.
Who wants to be the first to try?
-------------------------------------------------------------- EDIT -------------------------------------------
Nevermind, I just got confirmation from Zibri that the bootrom locations are NOT blank.

Still...I don't get why people want to go back to 3.9BL?? to use Google maps, really??? I'm not compromising a $500 device just to use Google Maps fully! it just doesn't make any logical sense to downgrade the BL for one feature...
now, if we are talking about baseband, that would a better reason, but then still, if you downgraded the BL your should not be worry about anything then, right? and if that answer is yes, about what? Apple will still support it...
btw could someone explain me this? it's from ZiPhone's help menu...
so why people have their iPhone unlocked with iPSF, running at latest baseband (4.03) with no problems execpet the signal.app running at every boot? shouldn't the phone complain then?
ipsf "method" corrupts the seczone. And baseband 4.03 KNOWS that
So.. thank ipsf team for this you iphone, for now is "tied" to baseband 4.02.

I installed LocateMe 0.5.

Tap on google locate and it works (give me Blue Circle).
Prior to locateme, it did not work.
may be this a "lucky" thing ?
not lucky - this is a known way to fix the locate me feature when on BL 4.6 and 04.02. It just needs to be done every time you startup your phone (Locate me or Navizon).

Just look how far unlocking etc has come in the past month or two. 6 months ago nobody could have predicted how far the unlocking methods/community has advanced.
However, i may be wrong :p
