  • Hey Very happy Fast service. Worked as expected but I was not able to delete carrier bloatwares at first cause I had to deal with a ''bootloader unlock allowed: no'' problem. I’ve finally been able to root the phone with Towelroot. I found an uninstaller that was able to do the job. Try the phone with a SIM from Bell Canada, worked Thank you Sister going to Europe this spring will be very happy.
