Lurker since the N770 days. First post.

I'm currently on a Sailfish X and it has severe problems with roaming.
My experience is reported on togheter.jolla.com (https://together.jolla.com/question/...obile-network/)
But it's not fixed on 2.2.1.8 and abroad while roaming the device will not connect to a operator (my sim works fine in my Jolla 1).

Can anyone help with reverting back to stock Android?

- I want to update to the latest of everything there and reflash sailfish.
- I did backup my TA partition prior to flashing
- Do not have access to a Microsoft Windows machine

So,questions then:

- Where do one find the stock Sony image for the F5121 (where would you download them from)?
- What tools do one need to flash the images?
- In what order do one flash them to restore the TA partitions?

I have done some flashing on Samsung and Motorola devices, but none in the Sony world. High level pointers would be greatly appreciated.
