Does this kernel work for all 3 flavours of the z3 compact tablet? I am asking is as I read that you are developing with the wifi only version while I have the lte (SGP621) version.

I'm not sure, I don't know what the differences in kernel, but I don't think they have a lot of differences and probably it should work

Great!

krabappel2548, great work men! :good:
Very nice

Do you also know if the bootloader is still intact?
I ask this because the algorithms for noise reduction, Mira Cast and better pictures in lower light are protected by DRM and the process of unlocking the bootloader removes it from the software.
So basicly if the bootloader was unlocked we should also loose the named algorithms .
And you could loose waranty if you have to bring it back to the store for problems.
Of course not for Root/Custom ROM issues: That is still the responsibiliy of every user

Edit: Did you know that you could earn money? They reward people who can root the Xperia Z3. For details see http://forum.xda-developers.com/z3-compact/general/bounty-root-unlocking-bootloader-method-t2940539

I have installed the kernel and TWRP works fine.

The kernel seems to be the same as stock. The only difference I have found is that /system is rw from boot. If I

mount -o ro,remount /system

it becomes read only as expected. After this it is not possible to mount rw again (Operation not permitted) which is the same as stock.

I've flashed the kernel in fastboot, how do I then install superSU??

Download it and flash in recovery or enter recovery, then reboot, it will ask to install supersu.

hack without root

Hey krabappel can an app be hacked without having root..?
I ask this because lucky patcher manage to hack an app and I have no root and locked bootloader.

First thanks for your hard work. Now I have some questions.

Is the kernel for wifi version 16/32gb?

How to open the bootloader without loosing the specific sony bravia and drm files. To backup them would be nice.

Thanks a lot for your time and work

Before there is a root for locked bootloader you will always lose them.

Question, Do you lose Sony's proprietary stuff when the bootloader is unlocked? Also, we will still receive software updates once unlocked and rooted? Thank you.

I am not sure about Sony proprietary stuff since I have not really used any of that. To me the tablet seems to work just fine after unlocking the bootloader.

Updates for the Sony applications like "Movies" are not working for me and it is probably caused by the unlocking. Waiting for CM12 so I can get rid of the Sony stuff...

If you aren't on stock kernel OTA updates will fail to verify. When you flash back stock kernel from an FTF with Flashtool it should work I think. Don't update through pc though. Use ftf files for safe updates, since pc companion might have a risk of bricking the device
