    Thanks for sharing. Did you already had a chance to verify the GPS issues having with 3.19 down to 3.17 ? I will update to this 3.22 in the next days to overcome some random ghost touches that I have with 3.15.

    Did they fix the damn memory issues? I know these are more related to Android 5, but still :)

    Sorry to say, neither Nubia tool 2.00 nor 2.10 is working in case Firmware 3.15 is running on the phone. Same PC, same driver which I used to update my phone from 1.59 –>1.64 –>2.13 –>3.09 –>3.15 fails.

    The nubia tool (both versions) recognizes the phone, allows to select the firmware folder (phone icon is marked in green), but as soon as I hit the Start button it verifies something and fails with a chinese message including the word "modem"twice.

      Erata: It works with the Nubia tool updater 2.0.0: 


      (requires installed Microsoft Visual Studio C++ 2010 Redistributables)

      but not with the nubia NX505J Updater 2.0 !

      Anyone getting a similar "modem"error should check the post linked below for a quick solution (it's in Italian, use Google translate):

      1. Go under C: \ Program Files \ Nubia NX505J Updater \ Config \ Download (or your path where you installed the tool under C)
      2. Make a backup of the original file EMMCDownload.ini
      3. Open the file with Notepad ++ EMMCDownload.ini and try these two strings:

      Version \ Internal \ Modem \ = Intrinsic NX505J_Z0_CN_DSXP K1JD11H164;NX505J_Z0_CN_DSXPK1JD11J213;;
      Version \ Internal \ Modem \ Extrinsic = NX505J_Z0_CN_DSXP K1JD11H164;NX505J_Z0_CN_DSXPK1JD11J213

      4. delete them, save the file and try again to install   ITS OK
