[Q] GPS Crashes during Cold Start

[greatanjum]

On my QMobile A6, having 1Ghz MT6575 , Android 4.0.4:
GPS crashes frequently during cold start and GPS beacon disappears and GPS Test App need to be restarted to restart GPS. While analysing the GPS debug i found that the
GPS chip could not use LTO.DAT file
GPS timming is in correct, although i sync my device time frequently as you can see in the extract from GPS Debug log
