Optus MyTab Upgrade

[Guest nech.q]

Hello everyone, I kinda stuck on Optus MyTab upgrade process, my situation is:

1. I rooted this tablet before (long time ago, I can't even remember what app did I use...Universal...something like that if my memory served me correctly.) and I unrooted it last night.

2. Then I followed the instruction (power off and power on) and stuck on android icon screen after I pressed and held volume up and down buttons, that little red light on the corner turned on all the time.

What shall I do next? I tried to recovery the device, but got no idea how to do that :)

Please give me a hand, tell me how to figure it out specifically, I mean step by step.

THANKS!
