  • [Beta] DownBase for OSX


    Digitol has coded up a nice GUI for baseband downgrading. This is intended for those that upgraded a 1.0.2 unlocked phone to 1.1.1 resulting in no phone calls or txts, even after restoring the firmware back to 1.0.2.

    It will not restore your IMEI but it will get your phone's baseband back to a point where anysim will unlock it for use allowing you to make calls and send txts, etc again.

    First you need to use iTunes to get your iphone's f/w to 1.0.2. Then you use app tap and installer to get ssh and sftp running. Upload the files in this archive (besides anysim) to /usr/bin/ on your iphone & chmod them to 775. Make sure you are connected to your wifi network and the autolock feature on the iphone is turned off. Enter in your iphone's ip address to DownBase and click downgrade. The process should take under 5 mins. When complete there will be a pop up telling you to run anysim (included in the archive). Install it and run it and your phone. You should once again be able to make calls and such things running 1.0.2.

    Download DownBase 1.1 here

    If we choose to continue development a future release of DownBase may upload the required files for you and restore your IMEI as well.

      i may get fussed at for asking this (it seams some people are on a shrot fuse today). I have a LOCKED iphone and only want to get back to a normal compleate 1.0.2. will this program do that for me without unlocking it? if so do I need to make any changes on how I do the process?

      So this basically sounds like follow the downgrading base band guide http://modmyi.com/wiki/index.php/Dow...1_to_1.0.2_OSX

      until step 12 and then the program take over? Sounds easy enough. Thank you for making this program. I have followed the step by step guide with no success even though it all went correctly so I hope this works.

      hey buddy don't be a hater. I'm only stating that the baseband from 1.1.1 to 1.0.2 didn't work for me for some reason. it just kinda hung up while using terminal. I was only asking since this one seems like it eliminates the use of using the terminal it may be easier to use. thats all. If you can't be constructive don't reply. I've been through almost all the forums to look for someone in my same situation.

      Well I guess this does not work for everyone. I followed the instructions and everything went as it should but I still get the same result which is I get full bars for a second and then they go away and it says no service. Any ideas on why?

      i think because either you dont have a strong signal. or, your phone still isnt unlocked.

      Catmando, You are getting confused downgrading the Firmware to downgrading the baseband. When you donwgrade the firmware, you then have to downgrade the baseband as well to get your phone working again.
      Go to settings->General->about and at the bottom check your firmware, it might start with a 04, that means, you need to downgrade, if it starts with an 03, then you are good. I recommend using unlock.app not anysim and dont confuse unlock.app with iunlock.app

      why do i keep getting this message in the down base. the message is bigger but i think this is the most important part.

      "add correct host key in Users/jose/.ssh/known_hosts:1"

      Hey Nemesis45,

      I have to double check my work what are you using to chmod the bin folder? I think i didn't change it from 755 to 775 the numbers are real close.

      I think I may have got very lucky today. My iPhones safari started crashing alot so I took it to the apple store, (I had 1.0.2 unlocked). I told them since I had changed my # I didn't have the original sim in the phone and was worried about the upgrade. They told me it would be fine and they done the upgrade and bricked the phone, then they asked me all the questions I said no and they replaced my iPhone. I have at&t so I would not reccomend this to anyone with another carrier.
