Wireless not activating on a TC70

Hi all,


I recently upgraded a TC70 to the V1504 image (this one : Release Notes).


After following the update instructions and doing a factory reset, the wifi refuses to activate, the wifi settings activity displays the following message : "Tuning Wifi on...", but nothing happens and every available option is greyed out.


Model number : TC700H-KC11ES-01


Any help would be welcome, thanks in advance.


Have a good day!
