[2.0][Solved] Never unlocked iPhone > Downgrading to 1.1.4
i couldnt find my exact question.. I seen you can downgrade your 2.0 back to 1.1.4 if you accidentally upgraded. But that was for a iphone that has been unlocked already and had the boot installer or something like that.
Now my question is, what if i bought i had a apple iphone that has never been unlocked but already been upgraded to 2.0. Can i downgrade it and then unlock it? Or did it have to be unlocked before, i could re unlock it, haha if that makes sense. thanks guys
If you upgrade your software to 2.0 . currently there is no guarantee you can go back.
It has nothing to do with whether you were locked or unlocked before.
2.0 upgrade installs baseband that none of the current tools can reliably downgrade.
You have to wait for the new tools to do it.
Well that makes sense.. i was gonna buy my buddies iphone but i guess i might wait.

Ofcourse you can downgrade back to 1.1.4 and unlock / jailbreak it.
You'll need to spend some time to learn the trick as its a matter of timing / judgement on pressing the home and sleep button to fully drain / wipe out the iPhone and leaving it completely blank dead screen... as soon as it tries to restart / turn off (iTunes must be opened btw)... LET GO off the top sleeper button but STILL HOLD THE HOME BUTTON... make sure this is done for approx 10 seconds... iTunes will then detect the iPhone after some time and make a sound ... that its connected... then click alt (for mac) or shift key (for windows) and click RESTORE... then browse the 1.1.4 which you may have previously or google for the file / download... then yeh select it and you'll notice the iPhone goes white and flashes and then starts to restore...
However not tried this on latest iTunes as i heard you need to uninstall this and install 7.6 version... so try as it is now if not then repeat it after you revert back to previous iTunes version
If still stuck, let me know and il make a video of how to do this for you / others or a simple guide to follow.. but im sure theres already other guides out there in google if you got time to snoop around...
after 56 hours of headaches heres the technique
for 1.1.4 firmare just google it if you dont have it
download itunes 7.5 if you havent done so
but first restore your phone to 2.0, i know it is a bitch but it has to be done correctly
learn to put your phone in dfu mode not recovery mode they look the same but it needs to be in dfu mode
now once you have restored the phone to 2.0 erase everything apple on your computer that means itunes, quicktime, safari, bojour, ipod, and then go into your personal music folder and delte the itunes folder there
once done go to oldapps.com and download itunes 7.5
now you must put the phone in dfu mode and run itunes dont worry when you cut itunes on and it says it isnt comaptible with the iphone
You will need the following :
iTunes 7.5 : [itunessetup7.5]
iPhone1,1_2.0_5A347_Restore.ipsw : [download - 2G]
iTunes 7.7 : [itunessetup7.7]
iPhone1,2_2.0_5A347_Restore.ipsw : [download - 3G] This is Only For iPhone 3G
KiPhone Windows : [KiPhone]
Uninstall iTunes 7.7 if you have it and restart your computer
Install iTunes 7.5, iLiberty+ & KiPhone. Make sure only iTunes is running
Enter the phone in DFU mode (You must have the iPhone connected to the computer and iTunes running). To do this, hold the power & the home button down for 9 seconds. Why 9? Well people say 10, but it depends how slow you are at counting. Too short and it doesn't work, too long and the apple logo appears. When you hit about 6/7 the screen should turn off, leave it for 2 more seconds and release the power button, STILL holding the home button. If all went well, you should NOT see an
apple logo, the screen should be dead. Keep holding home until windows/Mac informs you that it's found new hardware, OR iTunes tells you that your iPhone is in recovery mode. Remember, screen should be blank
Shift/Option click the restore button in iTunes and select the iPhone1,1_1.1.4 firmware you downloaded.it should restore back to 1.1.4 However, you WILL get an error message when restore is complete, something like 1011, 1013,1015 That's a good sign This is normal and
expected. An error 1601, 1602, 1600 or anything else is not ok.
Your phone now should be "stuck" in restore mode, you should see the old type "connect to iTunes" screen. run iLiberty+ Click the Other Tools tab and select Jump out of recovery mode. Keep your eye on the bottom right of the Liberty window it should change from a flashing recovery mode to disconnected within about 5/10 seconds. If it does, that's a good
sign. If it doesn't, you may need to hard reset the iPhone (holding power and home until screen goes off) and try again. Once it kicks it out of recovery mode you should see the slide for emergency calls screen on 1.1.4.
If you have the bootloader 3.9:
You can use this option to erase, which baseband do
want. 04.05.01_G, 04.05.02_G, 04.05.03_G AND 04.05.04_G too.
Check "iErase" AND "Debug" and press "start"
If you have the bootloader 4.6:
You can use this option to erase the baseband, if isn't
04.05.04_G. If it's the 04.05.04_G baseband, you must
downgrade the baseband first, lock under "Downgrade Baseband"
you have the bootloader 4.6 and the 04.05.04_G baseband -> run first "Downgrade Baseband"
Once done you will need to restore the iPhone one more time to 1.1.4 using iTunes. Shift clicking restore should do it, no need to put into recovery mode.
This is the hard part, run iLiberty+, select what options you want, select "Go For it" and wait. Once done you will be back your iPhone 1.1.4 Unlocked
If you think you are in DFU mode and keep getting error 20 from iTunes restore, you are not in DFU mode. An iPhone in DFU mode has no image on the screen and looks powered down.
you might get reporting error 160x (1600, 1601, 1602, 1604 etc) on the iTunes downgrade while in DFU mode. You may still have some residual files left over from the 7.7 install. Make sure you are in iTunes 7.5 with drivers from 7.7. I suggest trying another PC with itune 7.5
I would like to second that question.. I just got an iphone and upgraded as soon as I got home in itunes7.7 now am I screwed until Pwnage for windows? unless I find a mac.
