I've just bought a Sony Xperia M5 3 days ago after my Xperia C has had its final breath, it came with marshmallow 6.0 out of the box and there was a pending update, I tried installing it, it downloads the update, restarts then a minute after restarting it shows a message that the update has failed.

what I've tried:

using PC companion

factory resetting the device

in total I've tried about 10 times, I've done some research here and nothing seems to help, please assist.

Dear Now PC Companion not support for the updates. so try to update using Xperia Companion. and if you have already try with Xperia companion there is a another way to update phone using Flashtool. you can flash you phone using flash tool with or without loosing personal data. i think it will be helpful for you.

thanks

actually I realized when I googled PC companion it gave me Xperia Companion, any link for this flashing tool and does it affect the warranty?
