I bought an at&t htc one (m7) mobile from the us
i managed to unlock it with a code. My issue is that the current software is android 4.1.2, Sense 5 and the mobile cannot find the updates (guess because I am outside of the US)
What should i do to get the update
can I download the latest software from the internet and do a flash recovery? or should I flash it with earlier updates first?
Is there an easier way to update?
Can you please explain how to do flash recovery?
