alright osx baseband downgrade guide coming up just from me to you(all)

[meatwagon]

All right! If any of you have "bricked" iPhones from upgrading unlocked iPhone's to 1.1.1, you are now able to downgrade without paying a dime!

2. extract the ramdisk file from it by typing

dd if=694-5259-38.dmg of=ramdisk.dmg bs=512 skip=4

I tried that in terminal

XXXXXXXXXX-computer:~/Desktop/iphone baseband XXXXXX$ dd if=694-5259-38.dmg
dd: 694-5259-38.dmg: No such file or directory


my 694 dmg isnt -38 but -5 and i got the file from the hyper link.. any suggestions!??!

Will this work on an unlocked 1.0.2 phone never updated to 1.1.1?

[wawawa11]

will this work on brand new iphone with 1.1.1 out of the box?

Why would you want to use this? Your phone is fine. Jailbreak it and wait for the free unlock to come out.

So cash when will you be posting that guide for the baseband?

[meatwagon]

i cant get com.apple.CommCenter? to stop
launchctl remove error: No such process


cash, any word on your tutorial?????

[ddochi11]

I bought an iPhone that was originally unlocked (i don't know which method was used...), then it was upgraded.

I have downgraded to 1.0.2, and everything is working except the phone functions.
I also unknowingly tried to unlock the phone with one of the free simunlock services, but obviously it didn't work.

However, I have read that I should not attempt to downgrade BB if I have modified the BB with some of the unlock programs.

My modem firmware is 04.01.13_G. It seems this is what it's supposed to be.
How do i know if my BB is messed around with?
And can I still downgrade BB?

Thanks in advance

Do you think an easy step by step program like simfree will come out and you dont have to do all this stuff? just click and go? would make it alot easier, faster, hassel free, and error free

[hat]

i have already unlocked my phone with anysim my phone is running on 1.0.2 my phone is working fine i am able to call if i do this process my phoen will get bricked pls help me as i dont want to mess up by doing this and lose what i have

thanks

[EZ2ENVY]

i also have an unlocked iphone 1.02 that works and used anysim,

I want ppls opinion, do you think i should update the phone and use these new 1.1.1 jailbreakers and unlockers?

Or should i just keep it the way it is? and if i decide to do this, do i have to restore it to the 1.02 from the downloaded link or since 1.02 is on my phone already unlocked by anysim, can i just start this proceedure

PLEASE ANY HELP WOULD BE AWESOME

Better instructions coming soon by cash. This was the quick guide which was from the original author. Cash is rewriting as we speak. You type that in Terminal.

WHERE I TYPE THAT?

AND WHERE I DOWNLOAD firmware 4.0

THANKS

[Mirza513]

Okay here is a quick guide with what I did to "unbrick" my iPhone

Follow this guide to downgrade your iPhone firmware back to 1.0.2 (but still having BB firmware at 4.01)
http://modmyi.com/wiki/index.php/Dow...firmware_1.0.2

After you have finished that guide, you should be looking at your Springboard.

STEP 1
1 - Connect your iPhone to iBrickr
2 - Go to applications and follow the instructions (it should ask you to restart phone twice)
3 - After you finished that, browse the applications and install - BSD SubSystem, Mobile Terminal, and anySIM 1.0.2
(if the Mobile Terminal is acting weird and it's not letting you type in commands. Delete BSDsubsystem and install it again.)

STEP 2
1 - After that, download the files that Poetic_folly provided here
2 - Extract the files and rename secpack.bin to just secpack
4 - Now upload the following files to /usr/bin using iBrickr. (ieraser, secpack, ICE03.14.08_G.eep and ICE03.14.08_G.fls, bbupdater)

STEP 3
0 - Tap the Terminal icon and enter the following commands
1 - launchctl remove com.apple.CommCenter
2 - cd /usr/bin
3 - chmod +x bbupdater
4 - ./bbupdater -v (the v stands for versions I guess. This will show you which BB version you have)
5 - chmod +x ieraser
6 - ./ieraser (Wait for it to finish)
7 - ./bbupdater -f *.fls -e *.eep (Wait for it to finish)
8 - ./bbupdater -v (Now check if you have BB version 3.14. If not then something did not go right. Try again)
9 - Tap the anySIM icon and let it do it's thing (Make sure the auto lock thing is set to never)

-Restart your phone and you should not get the "Incorrect SIM" error anymore
-You should also have the correct BB version now along with the correct IMEI number


I wrote this from memory, I hope its accurate and for the record, I don't know much about the unlock process or what its doing. I just followed the instructions from the first post

All credit goes to the people who made this possible!

Good Luck Guys!!
