Default I'm on 14.1.G.2.257, wait or try to root?

Hi guys! thanks for your time on reading this.

I have an Sony Xperia Z1 C6902 with 14.1.G.2.257 firmware. I bought it 2 weeks ago on USA (NY).

I saw that I got to downgrade and root, and then flash a new pre-rooted 2.257 firmware. I tried a lot of roots toolkit but obviously non of it works.

Im a little scared about to flash a tft to downgrade an lose signal or something and can't go back to my actual firmware (because of no root, no rom backup )

SO, its better wait for a root toolkit for my actual version or try to downgrade?

thanks again for the time! hope you have a nice day guys

If you really need root then I say go for it. Just downgrade to .534 with flashtool, root it with root many android, then upgrade to .257 with OTA

You can always make your own FTF file yourself so you can flash it back. There is no danger in flashing them and you don't need root.

Won't you lose root by doing OTA after?

NO YOU WILL NOT

Read any of the several guides in the general section about how to achieve root on 257 FW

Not trying to thread-jack, but I was under that impression after reading guides saying you will need to re-root after flashing FW OTA 257.

Sorry for the ignorance....

Then you read them wrong, they all say that if you downgrade to 534, root then upgrade OTA you will keep root

Thanks for your quick reply!.

Sounds a little complicated but I will searchfor how to make my own ftf.

My problems is find a correct image to flash with flash tool. I'm a little scared to flashe the wrong one. I also didn't found how to make backup of my actual FTF without root, but again, I will search for it.

I want root first for install adaway, I used my old one x with it and now I cant stand for the ads... And I need 2 whatsapp ( one for work and one personal). Just need root for that.

thanks again. hope you have a good day
