PC companion doesn't want to update my rooted Z1 compact.
After PC software preparation and after I accept the "information" my connected phone powers off (step which I think is normal) and then I get the following message:
"The phone contains modified software that cannot be updated"
"Sony update Engine failure (error 2003)"
Can someone help ?
Bought my phone in March, works well, runs 4.4.2 and was rooted.
Tks in advance
