Simple Root for Unlocked Bootloaders (SGP311/312)
It was clear that rooting some Sony devices was not as easy as it should be. This is for unlocked bootloader users, who want to quickly root a stock ROM by flashing a rooted boot.img. It is for the POLLUX_WINDY (ie. the SGP311/312) devices ONLY.
Do not install this on the Pollux (tablet Z with LTE), or it will no longer boot - use flashtool to fix it
There may have been some in the past, but these tend to be full of other "tweaks", like hideous amateur boot logos, and stupid changes like setting ro.secure=0. That's a bad idea, it can break things, and frankly, I know from experience of myself and others that there is a need for a FAST way to root your unlocked device after flashing a new ROM, rather than messing around with downgrading and OTAs.
This will NOT work on locked bootloader, but this is not intended for them. This doesn't include 9001 different recoveries either, like some "kernels" do. This is the stock kernel, with root added, and nothing stupid added.
There is one security improvement made - ro.adb.secure has been set to 1. This is an important security feature, please don't complain about it. If you don't use ADB, you'll never see it, and it won't change anything. If you use adb, it will offer you greater security on 4.2+ stock Sony ROMs, which don't have this feature enabled. You will be prompted to accept the computer connection on the phone, just like in "AOSP" Android 4.2 and above.
The downloads are available above, in the "Downloads" tab. If you have a particular version you wish to request, simply post the kernel.sin. I have made this for only the SGP311/312 (Pollux_Windy) Tablet Z phone images right now, but will consider expanding it for other devices if there is demand and people who can test.
Enjoy simple root, without the nonsense. None of the "don't mirror my files" crap. None of the "please give me donations", none of the "omg credit me as the best person ever". Feel free to share, use, re-use, mirror, enjoy. And I think you'll find that these files are rather helpful for the unlocked bootloader root community :) I've been thinking about making them for months, but it seems that nobody has ever bothered to.
