[Q] Quick question on ftf 534 for Telus (Rooting)

Alright, Just got my xperia Z1 today. Looking to root it. Seems like I need the .534 FTF.
My phone is the C6906 from Telus. The only one with .534 ftf is for Rogers. Does anyone have the generic, the Telus or know if I can use the Rogers ftf to downgrade my phone in order to start rooting it?
Use any .534 for your model to start rooting. It doesn't matter if branded or not, you will upgrade anyway to Pre-Rooted by NUT.

[Q] US Generic FTF on Canadian C6906 (Rogers)

Hi there,
I am looking to flash 14.4.A.0.157 on my stock (not rooted, stock everything) Rogers C6906, but the only available option right now is the US Generic FTF from the FTF megathread. Now, I'm sure this will flash successfully since the hardware is the same, but will this affect my ability to receive OTA updates from Rogers? Lollipop is due in a few months and I still want to be able to get that.
Basically, what are the risks (if any) of flashing this generic FTF on my Canadian C6906, and can I revert back to the stock Rogers firmware if needed?

Not Needed no more, new to this whole to this Rooting/Flashing. Was able to pre-root o2 UK 5.0 rom myself and flash it, it was risky as it was the first time, but found it rather easy.

How to downgrade ME572CL back to JP sku Kitkat from pre-rooted WW Lollipop

So I have a Japanese model ME572CL which I flashed with WW lollipop firmware. I then downgraded and reflashed with pre-rooted lollipop following the guide on here. But now I would like to go back to the correct JP SKU firmware, the most recent version of which is V12.14.1.17 released last month, but I believe still 4.4.2 based. Can anyone tell me the correct steps to downgrade back to that firmware? Really grateful if anyone can help!
Sorry, please ignore this thread. I managed to get it done by myself and found that JP12.14.1.17 is infact lollipop. And there was an OTA update to JP12.14.1.19 too. So all good, now on Lollipop and Japanese. No way to root it, but nevermind.

Upgrade AT&t g900a from 4.4.2 to 5.0

I have a galaxy s5 that is not activated and would like to update to the latest stock, non rooted android version, which I believe is 5.0. I found a tutorial here:
http://www.droidviews.com/install-rooted-lollipop-on-att-galaxy-s5-sm-g900a/
that provides the lollipop firmware (Via the mirror, other link is broken).. However this doesn't work from 4.4.2.
I have been unable to find the 4.4.2->4.4.4 update. Does anyone know where to find this?
If this isn't possible, what are my other options to get to stock 5.0 version.
I was able to find them all from the following, https://www.androidfilehost.com/?a=show&w=files&flid=27720
