Ultrasn0w is now compatible with iOS 6.1

ultrasn0w ios 6

For a few days we have jailbreak untethered for iOS 6.x, but many of you have an iPhone 3GS (or 4) released with Ultrasn0w and you are waiting to update to iOS 6.1 so that ultrasn0w, the Cydia tool capable of unlocking some iPhones, will be updated to become compatible. In this way create a custom firmware with Sn0wbreeze or Redsn0w and update without uploading the baseband.

Well Musclenerd has already updated ultrasn0w, the tool for break free the iPhone by software, and is now fully compatible with iOS 6.1.

No new basebands have been added, so if your baseband was not releasable neither will it be now, the releasable basebands are 01.59.00 for the iPhone 4 and 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00 for the iPhone 3GS. If you do not have one of these basebands you cannot unlock your iPhone by software, you should think about unlocking by imei or looking for a unlock card compatible with your device.

You can check your baseband in Settings, General, Information, Modem Firmware.

You can download ultrasn0w en Cydia, you need to have done the jailbreakon your device and a baseband of the aforementioned.

    It does not work on iphone 4 BB 01.59.00 the signal drops at all times and there comes a point where it runs out of service and does not catch a signal

      It will be a bug, they will solve it! 😀

    Hi Gnzl, I have read where you say «In this way to create a custom firmware with Sn0wbreeze or Redsn0w» Can I use Sn0wbreeze or Redsn0w to take an image (backup) of my whole system? I could really use a .ipsw of the iPhone as I have it now (apps and tweaks from cydia included) thanks!

    1.    David Vaz Guijarro said

      No, You can not.

    2.    gnzl said

    I updated with a custom ios 6.1 to my iphone 3gs bb 6.15.00 and ultrasn0w does not work it keeps looking and then noservice ... it is worth more than I had the shshios5 and I downgraded with resdnow ... thank you very much for the contributions it is an excellent page ...

    Still not working on Iphone 4 with BB 01.59.00… :(

  5.   Ialbert said

    Hello! I have a 3GS, you know if the Redsn0w update compatible with iOS 6.1 is going to come out. Why doesn't sn0wbreeze activate the iPhone if you don't have the original sim right? And neither could the baseband be raised and lowered to release, right? Why to use evasi0n you have to have the iPhone turned on and without the tool to activate without sim there is no your aunt, right? Thanks!

    1.    SAPIC said

      the snowbreeze program creates a customized ios 6.1 etc ..., it keeps the database you have and of course if it has activation for the iphone 4 that does not have the operator sim which is tied to the device. SNOWBREEZE NUCA RAISES THE BASEBAND.

    1.    Sergio Ivan Samudio Vazquez said

      I have the same case as yours Odalis! I have a 3GS with an iPad baseband (6.15.00) Look, the ultrasn0w 1.2.8 already works perfectly with firmware 6.1.2. You can update with iTunes and then inject the jailbreak with redsn0w. Once you have the jailbreak ready you install the exploit untethered 6.1.2 (search in Cydia). You restart the phone and you already have the untethered jailbreak. Go to Cydia again and install version 1.2.8 of ultrasn0w, it will ask you to do Respring and VOILA! You can now use your 3GS .. Greetings from Paraguay!

    I have an iPhone 3GS updated to iOS 6.1, I install ultrasn0w 1.2.8 and it comes out without service. I have tried everything and it keeps coming out like this. what I do!!!

    1.    Bloddy angel said

      download RedS0w 9.15 and download ios 6.1 ...
      then Hit Extras-Select IPSW and then hit back and hit jailbreak ..
      later when I present you the obtions ... just leave the install ipad baseband checked and the others leave them unchecked ... yah just wait for the process to finish .... then you go to cydia and reinstall the ultras0w so you don't get into trouble
