[Q] How to upgrade to 10.2 from 10.1.3 stable
some one says that the build-in upgrade is not very reliable, and may cause problem.
do I need to flash the 10.2 as a brand new install, means:
ie: boot CWM, wipe factory/reset, install zip, install new Gapps (still need to find it)
will this still allow me to have the apps and files (like under /Downloads)
