Dead Xiaomi Hogmi

[Ultegra]

Hello, on January I bought a Xiaomi hogmi from Minideal.net.1-2 Days ago it stopped functioning for no reason.Doesn't charge or anything.It's a dead brick.I contacted minideal and they told me to send the phone back to them for repair and I will pay the shipping.I don't know what to do.Why repair and not a replacement then?Any ideas?

Hello, I guess Sw=Software and Hw= Hardware?

you can try to flash a hongmi ROM to check if it is just OS problem first
