Question about Apple iPhone Smartphone
This is how really people downgrade from firmware 2.0 to 1.1.4 on an First Generation iphone. all other videos just show what you have to do if you use a touch or if you have a at&t sim. Now dont forget that the extra steps are just for people that have the iphone with t-mobile.
Before you start make sure your phone is not on DFU or restore mode... and Itunes has detected your iphone...
You need to have an ATT SIM Card from an active phone for downgrade (it doesn't have to be yours)
1) download link.
the next file is only is you have t-mobile.
3)Install the itunes that was downloaded from link
4)Go to start menu, my music, itunes. change the name of a file called iTunes Library.itl to iTunes Library.itl9
5)open itunes, make sure phone is detected by Itunes and restore iphone by press down SHIFT , clicking RESTORE bottom at the same time, and select the file that what download that should say "iPhone1,1_1.1.4_4A102_Restore"
6)After the restoration, an error number '1015' may come up, that okay its part of the downgrade. After downgrade is done, ur phone should be on recovery mode
7)Open ziphone from your desktop and click the "do all button".. it will take like 5 minutes if if takes more than ten minutes go back and start from step 1. After this process is done your phone should be unlock.
8) If you are a at&t customer then your done. but if u have TMOBILE follow the next steps
9) Close all applications; (iphone and ziphone). Click on the file that was download that say "KiPhone" unzip it and start the app. that says this "ZiPhoneGUI - patched by kIREmK". once open you need make sure you select "downgrade baseband" and "debug boot" and then just click start. THis process may take several minutes.
10) After Kiphone has finished now you have to redo steps 5-7.
11)now this is for both at&t and t-mobile user go back to start menu, my music, itunes and rename the file that u changed in step 4 back to iTunes Library.itl
