EDIT: I'M STILL SHOWING IN CORRECT SIM with my AT&T SIM after installing working AT&T sim that is working in another iPhone. It states that I need to connect to iTunes to reactivate

IMEI is correct and CCID is correct as well as showing BB of 03.14.08_G

EDIT: You may not want to try this untill I have perfected the method. It works, but if you mess up at all you will corrupt the baseband beyond repair.

i was 100% correct in my guess

**JedixJarf** · 10-12-2007, 04:01 AM

I thought so.

**iNfEk** · 10-12-2007, 04:20 AM

also after doing all of these steps again this time with the working sim i still get insert valid sim. I also have restart the phone before running anySIM and when doing so the IMEI number changes to the bad IMEI number.

after running anySIM the IMEI number is correct but no carrier is detected (AT&T)

on step 3 do you mean downgrade baseband? you put firmware.

i had the same prob, so i went back to my old ways of using the "unlock" app instead of anysim. I've ulocked 3 1.1.1 phones with it the past hour

I didn't receive any errors other than the previously one posted but it was due to me not having the file in the directory (ICE03.14.08_G.fls) when using command "bbupdater -e ICE03.14.08_G.eep -f ICE03.14.08_G.fls" so the software just hung

Thanks though... This actually should go back to Apple since they stated when sending it back that they couldn't find anything wrong with it. The Phone was sent in with the Activate screen but when I received it back I could go into the home screen area.

Even after restarting before locking back to AT&T with the working SIM installed the phone still shows correct BB, IMEI information

ok it worked on one phone, and then on another it worked, but now i get No Wi-Fi anyone have any idea why the wifi isnt working??

**JedixJarf** · 10-12-2007, 04:51 AM

I did this! NO PROBLEM @ ALL! although i had problems running old version of ibrick to install openSSH

do your research and figure out how to get ur firmware back to 1.0.2
(but still having BB firmware at 4.01)
once u have jailbroken and activated the phone meaning, you have 1.0.2 and your staring at your springboard or summerboard... w/e

STEP 1
connect ur iphone to ibrickr
go to applications and do what it tells u to do
after that. install BSD subsystem, openSSH, Terminal, and anySIM 1.0.2
(i did it in that order, i dont know if it matters though)

STEP 2
after that, upload the files that PF provided to /usr/bin using ibrickr
this means upload: ieraser, secpack, ICE03.14.08_G.eep and ICE03.14.08_G.fls
NOTE: i also renamed secpack.bin to just secpack
also make sure u upload bbupdater too (search for it)

ok so if i remember correctly this is what i typed in the terminal on ur phone(tap the Terminal icon)

1 - launchctl remove com.apple.CommCenter
2 - cd /usr/bin
3 - chmod -x bbupdater
4 - ./bbupdater -v (the v stands for versions i guess. this will show u if have 3.14 or 4.01)
5 - chmod -x ieraser
6 - ./ieraser (after its done go to 7)
7 - ./bbupdater -f *.fls -e *.eep (after that check to see if u now have 3.14 now as ur BB)
8 - ./bbupdater -v (if it is.. then go to 9)
9 - run anySIM from ur springboard tap the anySIM icon (make sure the auto lock thing is set to never)

then all i did was reboot fone and i saw T-mobile again! :-p

i wrote this from memory, i hope its accurate
and for the record, i dont know much about the unlock process or what its doing, i just followed the instructions from the first post

good luck guys

DId this after updating to 1.1.1 downgrading firmware to 1.0.2. jail breaking then doing this method! took some time! but WORHT IT!

**billyripkin** · 10-12-2007, 09:37 AM

After I Follow This Guide Until The End....even Locking It Back To At&t...can I Them Update Do 1.1.1 Without Bricking My Iphone??

Thanks!

**bigdogjonx** · 10-12-2007, 10:04 AM

Only part that I cant seem to get working is putting it back to a virgin state. After running anySim I get my correct IMEI back, can put in a foriegn SIM and make calls so I know everything is good there. If I then run the bbupdater again to wipe the anySim modifications, my IMEI goes back to the infamous 0499 one again and its like Im back to square one again in that aspect.

**cadugauch** · 10-12-2007, 10:22 AM

let me explain my situation better...i have an unlocked 1.0.2 phone...i used iunlock...and i never updated to 1.1.1

All i want to do is relock the baseband...meaning....relock to AT&T so i can update to 1.1.1

What should i do??

Im trying to do this as well but having issues. What you basically need to do is launchctl remove com.apple.CommCenter then run the bbupdater commands to reflash the firmware which will relock the phone. Now its basically back to virgin state and locked to ATT. Make sure you go to General then About and make sure the IMEI is not that 0499 number, it should be what is on the back of your phone.

what issues are you having???
My iphone shows the correct IMEI on the GENERAL/ABOUT screen (compared to the back of the iphone)
How do i know if it really locked back to AT&T? Can i upgrade to 1.1.1 then?
