  • 1.1.1 Baseband Downgrade Achieved!
    cash edit: All you OSX guys out there I have written a nice guide for you, it takes a little time but i tried to be as detailed as possible.
    Click here for the Downgrade from 1.1.1 to 1.0.2 complete guide including baseband via osx


    Revan has made the windows guide click here

    All right! If any of you have "bricked" iPhones from upgrading unlocked iPhone's to 1.1.1, you are now able to downgrade without paying a dime!

    The guys over at RDGaccess.com have put together a guide on how to do it, here it is:

    "UNBRICKING 1.1.1 UPGRADE

    How To

    0. Download firmware 1.0.2 from apple: http://appldnld.apple.com.edgesuite....8_Restore.ipsw

    1. rename it to iPhone1,1_1.0.2_1C28_Restore.zip and unpack.

    2. extract the ramdisk file from it by typing

    dd if=694-5259-38.dmg of=ramdisk.dmg bs=512 skip=4

    3. mount the ramdisk by doubleclicking it (on mac). On windows use some HFS tools to peek inside it or get the files from someone who extracted it already.

    4. Put your phone into DFU mode and do option-restore in iTunes. This will reflash everything to 1.0.2. You will get an error at the end because it couldnt reflash the baseband. You will end up with a yellow triangle.

    5. Quit iTunes, launch iNdependence and quit it again, relaunch iTunes. Press the power button on the phone for 3-4 seconds. After like 10 seconds you end up on the activation screen.

    6. Complete the Downgrade by Jailbreaking / Activating, Installing SSh on to the phone etc. There are tons of wiki's about that so I won't repeat. (probably also true for step 4,5)

    7. Extract the baseband firmware and EEPROM files of 3.14 from the ramdisk of firmware 1.0.2. The files are named ICE03.14.08_G.eep and ICE03.14.08_G.fls and are located under /usr/local/standalone/firmware.

    8. Get the Secpack of baseband firmware 4.0. Its at the bottom of this post.

    9. Download ieraser2 from http://www.fink.org/ieraser/ or from Geohot's blog.

    10. Install all the tools on to the phone (i use the location /usr/local/bin)needed to get ssh access to the 1.0.2 firmware phone and upload ieraser2, the secpack, the firmware 3.14's FLS and EEP file and anySIM 1.0.2.

    11. ssh to the phone. Stop CommCenter? by typing:

    launchctl remove com.apple.CommCenter?

    12. run bbupdater -v. it will tell you you run version 4.01 of the baseband.

    (bbupdater is a tool by apple which is also on the ramdisk)

    13. run ieraser2. This will WIPE your baseband, given a file "secpack" is in the same directory and this is a version 4 secpack.

    14. run " bbupdater -v " again. it will not find any firmware now. 15. run " bbupdater -e ICE03.14.08_G.eep -f ICE03.14.08_G.fls " 16. run " bbupdater -v " it will tell you you run version 3.14 At this point in time you will still have a IMEI number starting with 004999... and its not of use yet. So still bricked but at least downgraded to version 3.14.

    17. run anySIM Version 1.0.2 (note that older versions might not be good here as 1.0.2 has a lot of fixes for this kind of stuff).

    Now you have a unlocked 3.14 baseband with IMEI being your original one! Congratulations you now fully recovered from your update 1.1.1 and are back to 1.0.2.

    If you want to return to virgin state again you can stop the commcenter again and repeat " bbupdater -e ICE03.14.08_G.eep -f ICE03.14.08_G.fls " again to reflash the "locked" version of the baseband.

      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.

      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)

      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

      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!

      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.

      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?

      As I stated before, everything works including using anySim. Once I run that anySim my IMEI (when going to General then About) shows the correct one as noted on the back of your iPhone. Before it has that bogus 0499 one. So now Im working again, can put in a Tmobile card and working just fine.

      Now if you want to go to virgin state, you have to run the bbupdater one more time which will erase the unlock by anySim and relock the phone, however everytime I do that the IMEI returns back to that bogus 0499 one, which is still a problem, because its going to cause problems if you upgrade to 1.1.1 not to mention you get Invalid SIM even if you have your original ATT one in there.
