Windows baseaband downgrade - Baby steps ;)
Developed with the help of IRC people based on Iphone elite wiki.
Tested with week 30 iPhone, activated and unlocked to use a BrasilTelecom SIMcard and upgraded to 1.1.1 without knowing.
So i had to make the 1.02 restore before all this steps.
You will need a 1.02 phone with bsd subsystem, terminal and anysim 1.02 already installed. If you downgrade from 1.1.1 like me you probaly have this now.
Create a root folder call it unlock - c:\unlock
Download to this folder:
Windows programs (links to follow next):
Iphone binaries (links to follow next):
On your iphone open terminal and type:
On your windows open cmd.exe, on a Vista computer open explorer and type cmd.exe at the address bar
pscp ieraser your.ipod.ip.address:/unlock/.
pscp bbupdater your.ipod.ip.address:/unlock/.
pscp ICE03.14.08_G.eep your.ipod.ip.address:/unlock/.
pscp ICE03.14.08_G.fls your.ipod.ip.address:/unlock/.
pscp secpack40113.bin your.ipod.ip.address:/unlock/.
Now putty will ask if you want to connect to the iPhone, answer y and
type the password, dottie.
Now you are on your Iphone terminal, please pay attention on what you´re typing.
chmod +x ieraser
chmod +x bbupdater
launchctl remove com.apple.CommCenter
You had make the binaries executables, stoped the com.apple.CommCenter and you executed bbupdater to view what version is your iphone baseband. Now its time to rename the secpack, don´t forget to rename ieraser only accepts secpack as the filename, and let´s erase the baseband.
mv secpack40113.bin secpack
Now run the bbupdater command again, see if your baseband is erased. Type
Now lets reflash the baseband, to do type:
./bbupdater -e ICE03.14.08_G.eep -f ICE03.14.08_G.fls
This will flash the 3.14.08 baseband firmware back to the iPhone, bbupdater will run for 3 minutes.
When its over let´s check if it´s reprogramed the 3.14.08 baseband, type:
The correct answer ;) :
pinging the baseband...
eep version: EEP_VERSION:207
eep revision: EEP_REVISION:7
Now just reboot and run anySIM 1.02 ;)
Please correct any errors!!!!!!!!!!!!!
