Have you tried flashing the rom? And if it works flashing dont install the update it leads to boot dead phone happend to me and now it dont boot and blackscreen no led lights

Sounds like either the build has errors or hardware problem

Is there a way to fix the phone or it neee to go repairshop or need a new one?

How about us who loss the phone?? It will be on the guarantee or what???
