Hello tem,
After updating my htc desire 820 to 6.0 phone become dead, at service center they are asking to replace motherboard which costs 10, 000 inr

If 6.0 is not supporting in htc then why you are giving such updates i want solution for that

If proper solution is not provided by company then i will publish this issue at facebook/twitter etc

Note : i have not searched for update it came from system only

Thanku
