Acer ICS OTA
Acer has started the OTA process to bring Ice Cream Sandwich to all A500 devices. I got the notification that an update was available today. I've uploaded the base OTA file for those of you that would like to use it. It can be found here:http://downloads.tabletroms.com/blaz...F411D7F117.zipThis has not been modified in anyway. What that means is it will not have root or have any files removed or changed. It might not be installable as is.This is the gen2 file meant for the US. The update is called Acer_A500_7.014.02_041.205.01_COM_GEN2 by Acer. In the build prop it shows as Acer_AV041_A500_1.033.00_PA_CUS1.
Ahh I see. The link software link is not working.
All is working in the first link from XDA.
Also found this at the bottom of the OTA thread.
