Prije hard reseta probaj ovo, sa upaljenim mobitelom:
"I found something that worked on my phone and I hope it will work on other phones.
I logged into my Microsoft account and went to the "find my phone" section. I then chose the "Lock" option, which required me to enter a 6 digit pin code. This feature then turned my phone off. After I turned my phone on and entered the 6 digit pin everything seems to be working."
Mislim da ce to radit samo ako ima prijavljen taj mob na svom account-u, a ak ne uspije nema drugih opcija osim reseta sa gumbima.
Edit: Provjereno i radi samo ako je mobitel prijavljen, jer se inace ne moze doci do Lock opcije.
