[Help] How to update rooted 4.4.4 to latest without losing root

I have managed to downgrade my Xperia z1 c6906 to 4.4.4 fw. 187 and rooted it.

I wondering now what steps I can take to have it updated to the latest fw and keep root. I used flash tool to flash the 4.4.4 onto my phone and then used towelroot to root it.

I'm also unsure which recovery I can install on the device that will work.

I've searched around for some solutions to no avail and a lot of links for downloads were broken.

Thanks for your help

OTA Update Without Losing Root

I currently have the volume bug on the July 5th security patch on my Nexus 5 and recently rooted it. Is there any way to get the upcoming OTA update without losing my root access?

downgrade from 6.0.1 without root and without losing data?

so a family member asked me to downgrade his samsung galaxy s5 from android 6.0.1 to the previous version.
i've googled it a bit but only found ways where you either lose your data or need root and he won't let me root his phone.
is it still possible and could someone either explain or link me how to do this?
thnx

Am I Dead? (Losing Cell Svc)

For the past few weeks I've been losing cell service - a lot! With the phone at home where I normally get 3-4 bars, signal will suddenly cut out & I'll get the warning notification. BUT sometimes I seem to lose the phone part of the signal & the phone seems to have data - though even then it will often fail even when it says there's a data connection. (I hope this makes sense to someone.) Sometimes it reconnects on its own, but usually I have to search for network & re-register. And about 10% of the time it fails to register on the first or second tries. Variations on all this happen multiple times per day & I probably have any cell service for a total of 5-10 hrs on any given day. (But once in a while I do get a good day with almost no outage)

At worst, I could live with completely unreliable voice service for a while as I'm aiming to buy the upcoming new Nexus. The bigger problem is that I do need semi-reliable data - and when cell cuts out Cell Standby battery usage skyrockets.

*I'm on Wind Mobile in Canada so cell service is never perfect but this is WAY beyond normal failings.
*Wind has tested the network & towers at my apt & say all is 100%
*I've replaced the SIM card.
*I'm stock 6.01, not even rooted.

Any help/suggestions would be greatly appreciated.
