im trying to flash my xperia s to 6.2.B.0.211 so i can root it, i have installed all the drivers and each time i still wont flash. when i start the flash, it loads and tells me its done and to restart but when i try to run DooMLoRD_Easy-Rooting-Toolkit_v17_perf-event-exploit it still says 6.2.B.1.96 is running.
