Sorry to bump in,but my question is kinda related to this topic.
Can someone tell me where are stored informations about "my devices" (bluetooth) ?
I know that every setting is lost after flashing FS.
I flashed my phone (d750i) MAIN & FS twice (w800i & k750i),and i still didn't lost "my devices".
They were (and are) still in my phone after whole process.
