I have a problem. I bought the acer z2 duo.
I had microsim so until my normal sim comes I opened it and worked it for a bit.
I normally signed in with my google account and I downloaded also all the updates required from the playstore.
When my sim came I reset the mobile and put the sim in.
Once again I logged and everyhing but now Anything I want to download or Update I get the message
"Error Update for "XXXXX" could not be downloaded due to an error (403).
I tryed a data wipe a hard reset.. but also the same thing
I tried with and without the sim and with and without the sd card
Can somebody help me please on how to dont know.. maybe Flash the mobile to an original firmware or something?
I did searched for an apllication like KIES for samsung or sony application but I didnt found anything by acer.
Thank you in advance
