On mine z10 currently running SR 10.3.1.1877, my first unofficial release since I bought the phone in 2013.
Installing this leak was the last attempt to improve system performance and usability, but still I can't find a reason why continue sticking on this bad engineered sw.
It's not SO bad, but with many little annoying things, such as keyboard click not able to eliminate, battery life halved, general lagging, the appearance that there is something ruined in graphics and text rendering.
I prevent my wife upgrading to 10.3 on her z30 staying on 10.2.x, that I think is still the best BB10 os I saw.
So my question is what's the best downgrade path? What's the best 10.2.x release? Need I a blitz file?

By asking which is the "best 10.2.x release" you are setting yourself up again. What is "best" for one person may be problematic for someone else. For example, I had no problems on my Z10 using 10.3.1.1877 which you don't particularly seem to care for. You could go back to 10.2.x by using an autoloader from the archives; however, why not blitz to 10.3.1.2744 and see if that solves some of your problems?

Will try 1877 maybe will solve something.
I know it's not an universal feeling about 10.3, still I didn't understand why didn't work with me, I just have installed only few Android app and about 20 BB one, a couple of email address and some VoIP apps.
I thinked to be safe so was a surprise to discover these problems.
In the upgrade process I did also randomly loose some phone numbers with the data restore, another thing not critical but just annoying.

The best (for me) os is 10.2.2.1609. The best signal and battery life. Search function is better than assistant, call log is longer (30 days) etc.
