  1. P3113..?

  2. Does this procedure rest my tab and clear storage?
    thanx in advance

  3. If you reset from the boot loader then yes. If you upgrade from existing OS, then you’ll not loose any data. But it’s advisable to reset and clear cache before you upgrade. There are lot of apps in the market that can take backup of your files, make use of them.
