[CaptainChaos]

Heh I think someone should post this method drawn out in crayolas.

You have to be jailbroken wannabelean.

[tattoojack]

lmao

but then i remember this site!

[CaptainChaos]

I agree. Humanity is devolving.

[JStraitiff]

nothing is devolving i just think that people are getting lazier... look at all of the threads that are started and replied to "SEARCH"

lawl

[CaptainChaos]

Well I am not really fond of the search feature on here. It doesn't work so well. I tend to resort to scrolling through page after page within the respective forums to get what I am looking for.

At least I know now that I will be selling this phone as unlocked and that it is set up for future unlock failures to be correctable.

[JStraitiff]

^^ the search does suck here... but ... there is always google

[yoenoesz]

Omg, I've updated 2 iphones to FW 2.2.1 to test it, all the BL'ers of the Iphones are 5.09.. So I have updated it for nothing..

[sarunas4]

now we just need someone to figure out how to downgrade the bootloader to 5.08

[yoenoesz]

how to downgrade the bootloader 5.08? we can.. we can downgrade the 5.08.. can't we?

[confucious]

how to downgrade the bootloader 5.08? we can.. we can downgrade the 5.08.. can't we?

LOL yeah, right. Apple put those few bytes in there for nothing.

LOL yeah, right. Apple put those few bytes in there for nothing.

Geohot, the guy that found the exploit did say this though: "I figured you guys might have it. I'm convinced theres a way to make it run the 5.8 ramloader instead of the bb in ram. We can also do a yellowsnowish thing to grab the bb reset and command boot from the bootrom level, even if the main sig doesn't validate. Unlocks for all versions... And you guys make much nicer automated tools then me :P"

So there is hope.

Does anyone know GEVEY PLUS 2 work with iPhone 3G 16gig bootloader 5.09?
I just jailbreak it and downgrade to 2.28

[carlos.michell]

You will be alright. I hope the video was able to help someone out there.

Thank you for linking this =)

Im happy the video help you.

but you gotta have at$t to do that, so how would that help us?



thats just sad and pathetic, and a complete waste of a post.
beggin for thanks
really?




so are you mad at him for being mad at you?
or you're just mad at yourself because you had to have a kid figure it out, make a vid, upload it to youtube,
all so YOU could understand it?

wow

you can always tell when people are bored.

everyone is all lovey dovey when the exploits come out,
soon as it dont work for everyone,
the claws come out!

lmao

and if i make you laugh, you can thank me,
or go f$#k yourself.
i really don't give a s#$t

No, im mad at him for coming at me wrong. I have no problem letting some 13 year old show me how to downgrade my Baseband. If it saves me time and effort than im happy.

I have tried just about everything and have been trying to do for about 2 days straight now...it's so frustrating I want to cry. I just spent 200 dollars and bought my iphone 3g off ebay and all I want to do is unlock it! My firmware is 2.2 and baseband is 2.30.03 which i completely don't understand and have no idea how the baseband was changed and not the firmware. Maybe im doing something wrong in tattoos steps but I can never get the bootloader information to show up after i type in that command my no sim changes to searching and then my phone automatically cuts off. So I'm really not even sure what my bootloader is. I know you guys are sick of hearing these dumb questions but I am desperate and need any help I can get and in the "dummy" form, not that smart with all of this. please and thank you for you guys time and effort!

Sorry about that
after you put the 3 files on you iphone in terminal
you do the following commands

1. Type in: su
2. Type in the password: alpine
3. Type in: cd /var/root
4. Type in: chmod 755 BBUpdaterExtreme
5. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
6. Type in: ./BBUpdaterExtreme queryversion

after the "launchctl unload ..." you should get the searching in the top
do the next command
and you should see something like the pic i posted above
continue on if you see "ICE2_BOOT_05.08_...", if not that then you have 5.9
if you do continue and your iphone restarts carry on from here

1. Type in: su
2. Type in the password: alpine
3. Type in: cd /var/root
4. Type in: chmod 755 BBUpdaterExtreme
5. Type in: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
6. Type in: ./BBUpdaterExtreme update -f ICE2_02.28.00.fls -e ICE2_02.28.00.eep
7. Reboot Device

I hope this helps you.
and that you have the 5.8 not the 5.9

[ashannak]

if you downgraded it to 2.28 you can yellowsnow it ...what do you need the gevey plus ii for?

[confucious]

Firmware version says 04.22.01(yea i updated to 3.0 beta 2)

Oh dear!

Bootloader Version ICE2_BOOT_05.08_G2M3S2 (OR is this the bootloader?)

Subtle clue in the way it says "Bootloader Version"?

So there is hope.

Linky? He obviously knows a lot more than me. so there is hope.

Sure. He wrote it in his blog post in the comments. That was on about the 11th and there has been no update from him since, but hopefully he's still working on it.
