    If you can get the non destructive bar files then I think it should work

    The version you have is not a leak... it just hasn't been released for your device (it's the Z3's current).

    The procedure is the same. Grab l files and drop them into Sachesi. Same as you'd do for an update.

    On a side note Z10STL100-2/10.2.1.2947 +.2759 radio has given me some awesome battery life.

    Some people see the word leak and get all scared. As if their phone will stop working. 2947 best OS so far.

    It's the same procedure as updating using Sachesi. I did it recently using the Debrick bar files plus my radio file in the same folder and I found it was faster than using the Upgrade bars (but that could have also been because I used a different USB port as well but it took 26mins and normally it takes about 45mins using the Upgrade files and my other USB port).

    Update: I recently discovered that if you install the Debrick OS using Sachesi it doesn't update the app bars. You can extract the app bars from the Debrick OS using Sachesi or Darcy's BB Tools or just download the Upgrade Files which contain everything you need.

    Anytime you download an OS using Sachesi it creates and places the files in a folder that is named after the Software Release version number of the OS you're downloading. 2102 and 2126 are older ones you probably downloaded. I suggest you download and use 10.2.1.2160 for your downgrade since that is one of the most stable and trouble free releases so far. Feel free to ask for more info.

    I've seen it mentioned before but never with a definition.

    What are the debrick files?

    When and how do you use them ?
