Hi all this is the way I have just down back my base band to 3.14.08 and unlock as normal way before.

1. Get this secpack40113 from firmware 4.1 download from this attach from here (i have just rename it to secpack)

http : //w w w .m e d i a f i r e.com/?321ts5g9xly

Or download all in one package here :

http://www.m e d iafire.com/?0xysybsy4pt

(ieraser, bbupdater, testcode.bb, secpack)

2. Copy this new secpack and some old tool :

ieraser ,
bbupdater
testcode.bb
ICE03.14.08_G.fls
ICE03.14.08_G.eep

to your phine at directory :
usr/bin
Change properties to 755 (all x)

3. Run putty and type comand to reloaded CommCenter

#cd /usr/bin
#launchctl remove com.apple.CommCenter

Config minicom at same way before so that ieraser can run. When ok exit minicom and run ieraser

#ieraser

And it funny thing is all will back as original it mean Imei number will correct

Good luck to all

P/S : I have just test on 1.0.2 upgrade to 1.1.1 and baseband upgrade to 4.1 but not yet test it on original 1.1.1 so who have please test this way.

May be it long to remmeber this is sumary :

1. eraser new radio firmware (4.01.13) by new secpack so that it erase and clear version, Imei...
2. Flash it to 03.14.08 by bbupdater but it will say error at first.
3. Flash eeprom 03.14.08_D.eep by bbupdater
4. Re flash 03.14.08_G.fls by bbupdater So firmware for baseband radio will back to 03.14.08
5. Unlock by anySIM or iUnlock_reloaded

was yours 102 anysim unlocked then upgraded to 111?

I think right now all the 1.1.1 unlock is including downgrade to 1.0.2, downgrade your baseband to 1.0.2 and unlock it. you will have problem with upgrade to 1.1.1.

I need to have a bbupdater?
I dont understand that part?

The bbupdater must be from when i got my iphone in 3.14?
I downloaded one. its correct if i use this one?

thanks a lot

is this confirmed to work?

Yes I upgrade and downgrade it. But it different than original is EEPROm 8 or 7 just use bbupdater to flash eeprom it will come to 7.

Here in 1 package for you : ieraser , bbupdater and secpack40113

http://www.m e d ia fire .com/?9mg7mttwoey

After that run
#minicom -s

Confige it and run ieraser

Good luck

What do I need to do to configure after I run "minicom -s"? I did all steps up to ieraser, then I'm stuck at "waiting for data" I already have ieraser and secpack in /usr/bin

Best way is install BSD subsystem from installer so it will install minicome and data for minicom...

#minicom -s
Serial port settup --> press A change it to : /dev/tty.baseband
Save setup as dfl --> Exit --> Ctrl + A --> X to exit.
#ieraser --> it will run.

remember change all file that we copy to phone to x : 755
