[Guide] Downgrade: iPhone 2G on 2.0 to 1.1.4 + total unlock - best tutorial! ;)
I tried the method below with my iphone using lebara kontant kort in norway - works beautifully. NB! dont use this with iphone 3G - the hack is on the way but not ready yet for the public.
1. install itunes 7.7
(this is to have the correct driver / files necessary)
2. uninstall itunes 7.7 with appzapper
(this will remove itunes 7.7 but not drivers)
3. open terminal and type:
sudo rm -R /System/Library/PrivateFrameworks/MobileDevice.framework
(type in your admin password when requested)
4. install itunes 7.5 - get it from apple
5. reboot mac
6. rename itunes folder in music to itunesOld
7. start itunes - and click what u need - next etc. until u are in the app and have configured it like u want it. quit it.
8. plug in your iphone to the dock and the dock into the computer.
itunes helper will now start itunes again. After a little while u will get an error message saying u need a newer version of itunes - dont give a shit about this message - its bullshit ;) Just click ok.
9. Put iphone into DFU mode (the iphone WILL BE BLACK WHEN IN DFU !):
While your iphone is in the cradle - its dock - hold the home button on the bottom and the power button until the screen turns off - then count to 2 - (1 to 1.5 secs) - and let go of the powerbutton on the top of the iphone , but keep pressing home button until itunes reacts and asks you if you want to restore your iphone. The trick is to let go of the powerbutton before the apple logo would normally show.
DFU MODE INFO:
it does not take 10 seconds to get into DFU mode - people are full of shit!
hold powerbutton and home button:until black screen and in 1 second let go of the powerbutton (dont get to the apple logo and the iphone must be totally black with no graphics on it) but keep on pressing the home button until itunes tells you that u can restore your iphone - this takes some time - so dont worry - just keep on pressing the
home button on the bottom under the display and let go when itunes tells u that u may restore your iphone.
10. download iphone 1.1.4 firmware - but first turn off "open safe files after downloading" in the preferences so that the file dont decompress after download:
11. download pwnage tool version 1.1 on this page or any other place:
12. download the 3.9 and 4.6 boot loaders:
unpack this rar file - (get unrarX from macupdate.com)
13. Go back into itunes and option-click restore in the iphone tab - choose the iphone1,1_220.127.116.11A102_Restore.ipsw.zip file.
itunes will now extract this file and restore it onto your iphone.
When this completes - you will get an error 1015 which is a good sign.
14. Put your iphone in restore mode if its not allready:
turn off iphone- turn on with a tap on power while holding the home button - and hold the home button until itunes 7.5 tells u u need to restore your iphone.
Now u are in normal restore mode and not dfu like last time.
Restore iphone again! dont give a feck about itunes error code in the end.
15. quit itunes
16. start pwnage tool that u downloaded
17. hit browse .ipsw and find the 1.1.4 file u used in itunes.
18. hit ipwner:
after a little while your phone will start showing text - and quite a lot of text will show up after the iphone reboots. After a while its all done and the iphone is showing that u have to connect with itunes.
19. hit browse ipsw: choose the 1.1.4 file you used earlier via browse .ipsw button.
hit ipsw builder: you will now see a menu - general - custom packages etc...
turn on activate phone, enable baseband update , enable neuter bootloader, unlock baseband, and autodelete bootneuter.app.
image of the info above:
20. hit ok and choose the 2 bootloader files from the .rar archive u downloaded earlier and hit ok again. pwnage tool will now ask you where to save the new custom restore file for your iphone. choose your home directory in my case its the house with aRt next to it ;)
Pwnage tool will now work until its created the new custom restore file.
21. quit pwange tool
22. open itunes (your iphone should still be in restore mode - showing connect to itunes picture).
23. option click on restore in the iphone tab (the alt key plus mouse key) - and choose the new custom restore file you created in pwnage tool. Your iphone will now finally be totally cracked, hacked and prepared to be a full working iphone that accepts any simcard, uses edge if u configure it, jailbroken etc ! All the goodies will now work. iTunes will ask you to name your iphone and start a syncing process - to put your contacts on the phone.
The phone will now show a pineapple instead of an apple.
24. enjoy your hacked iphone!!!!!

Sadly, this method didn't work for me either. I originally tried making a guide using PwnageTool all the way but 1600 was my enemy. I also had to go the iliberty route to finish up and had to use kiphone to down the baseband. I've done this three times now successfully.
