Overall process

1)I have tested flashing only ClockWorkMode (CWM) Recovery v6.0.4.5 and higher for flashing lollipop. Other recoveries might work as well.
2)Download GT-P3100_ClockworkMod-Recovery_6.0.4.5_Non-Touch-UNOFFICIAL.zip. And install it first. (New Version:6.0.5.1 GT-P3100_CWM_6.0.5.1.zip.)
3)Choose your choice of latest lollipop ROM, gapps and chanfire supersu from here and copy to your external SDCARD root.
4)Boot tablet in to CWM Recovery v6.0.4.5 and take a backup of existing ROM. This is highly recommended.
5)Flash the Lollipop ROM, gapps and supersu and reboot.
