[Q] new firmware disable my root?

[bagiz010]

hey there!!
so i have the SGP521, and i understood that if i want to root it i need to flash older version of the firmware, so as it. - i did it! i installed the 17.1.A.2.69 firmware, and i rooted it sucseccfuly! but now i want to update it's firmware to the latest, and i don't know if it possible, that i will flash a new firmware and keep my device ROOTED. (i'm using Flashtool).
is there a way to only "update" the firmware without wiping the root (and maybe without wiping the user data too..)

thanks!
Tal.

Having read these three threads, I don't know and it seems the 511 trick works for the 512. Don't know if it will do the 521.

I'd like to know of the lollipop update coming will be rootable or kill root.

I think I will not take the chance and maybe lose my 4g LTE contectivity by installing other version firmware..
But i will wait for the lollipop update too (hope it will not kill the battery, like it does on almost every phone it's installed on)

but thanks very much for the help!!
