Whether it be a Computer, Laptop or even an Android device, if your device won’t boot but has valuable data on it, there is a very good chance it can be recovered.
It happens to us all at some stage and I have written an article on this very subject, here.
I am able to assist with anything from data recovery only to a full re-installation/upgrade of a new Operating System with as much data as possible recovered.
Please get in touch with brief details and I can advise if I think I am able to help you get your data back or point you in the right direction.
Please note, this excludes Apple devices.
