after the mod (v.0204) flashing you must install Acer 2.1 Cert.: copy Acer 2.1 Cert. "ACRSYS-4B032EBD.XRM-MS" to root of C: run cmd.exe as administrator and type in the command prompt: SLMGR.VBS /ILC C:\\ACRSYS-4B032EBD.XRM-MS ...wait for result SLMGR.VBS /ATO
I didn't... I flashed your modified 0204 BIOS dump and Windows 7 stayed activated on the previous ASUS SLIC2.1 activation, I've also successfuly upgraded to Win10 in the meantime
