I have received a security update in June 2018 and I
tried to update usually and after it rebooted showed me an error -
"Your phone has ever been rooted, this may result in system instability,
malware or spyware or privacy information leakage". I visited service
center in Visakhapatnam, AP with the name of Bright Infocom. They first
mentioned it was liquid damaged. I wondered why but as they are imposing
it is liquid damage I said ok. After that they informed me it was
problem with charging port and needs to replaced. I wondered again why
it should be with charging port when the error came in software. They
charged me Rs. 1500 INR to change the charging port. I hope Nokia
Support will help me in this issue of customer service center ignorance
and false information. I have trust in Nokia. I can send over jobsheet
and the error screen photograph of the phone if required.
Please do the needful.
