Haha....just kidding..
Well, download 4.3 and flash it through flashtool.
I remember we were losing IMEI if we downgrade from 4.4.2 to 4.2 so check for that...
I think there's method (ftf) to avoid that..
Search for NUT instructions...

Root Xperia Z1 C6902 android 5.1.1

Can anybody please tell me about any one click or any easy root method for xperia z1 C6902 android 5.1.1?
Or else just tell me how to downgrade my phone to 5.0.2
I am new to this forum so if i have said anything incorrect please forgive me.
And thanks in advance.
And also provide links if you know how to downgrade to 5.0.2

There is no way to directly root Z1 lolipop 5.1.1. You have to downgrade (to Kitkat 4.4.2 is the best), get your z1 rooted, install recovery then update it to pre-rooted lolipop 5.1.1
Use Xperia Flashtool to downgrade or upgrade firmware.

Thanks for the reply.
Can u list the steps and the links and
Also please tell me how can I downgrade to 5.0.2 lollipop.

no do not downgrade to 5.0.2 since its awful to root because you need to change from kingroot to supersu... just downgrade to 4.4.2 and install nut's recovery and it will root it for you in the process... then flash prerooted 5.1.1. and you're golden

Okay. Thanks for the reply.
Can you list the steps and the links?
You know I am just a little new.
Thanks in advance.
