I can confirm that it can cause a mistake on the first try. But, for me at the second attempt was fine 
Thank you sir! I was going crazy trying to get adb to work and finally I got it.Weird that it just succeeded in 1 try for me, it might have to do with different firmware versions. Mine runs on the model SGPT111NL/S.
Can you guys tell me what model number it displays beneath the SONY logo on the back? That might give a small indication, or not. Who knows.
ANYWAY.
I promised to make a vid, here it is:
Note: Quality sucks (not screen quality, but quality quality. It does display the process)
OP stated he doesn't know if we will lose root with ICS or any OTA update for that matter.does anyone know, would this prevent the imminent ICS OTA upgrade from working? Thats my only concern.
I realise that there may not be a way of answering this yetbut as root is not unlocked BL, theres no guarantee I can custom ROM to ICS, so I'm a bit hesitant with official ICS so close
Oh yeah?Since ICS will be on every tablet sooner or later, chances are 100 times higher that another exploit will be found that works on all of them, so don't worry about Sony doing anything![]()

bingoI don't think the concern is losing root. Its not being able to update to the new ics update once released. I'm curious too.
