Question [Q] Question about DooMLoRD´s kernel FW-136

Hi there,

I managed to root my Xperia Z1 using firmware 14.2.A.1.136 with the help of DoomLoord´s stock kernel FW-136_v01.

Upon what code is this kernel based? Is this a stock Android 4.3 kernel or does it contain Sony code? Is it based on Sony kernel code? If the Sony kernel is open source, after all...

I ask, because the original Sony kernel has some security features that might get lost when using a stock kernel without Sony extensions.

So, does DoomLoord´s kernel include Sony code or is it a "naked" stock Android kernel?

Thanks for any hint!

1. If you use 136, then use V7 for more features and more stable.
2. It is based on Sony Stock Kernel.
3. Flashing custom kernel need unlocked bootloader, which mean you'll lost your DRM key. This is Sony security which you meant, this is not kernel issue, it's just something you get from what you do (unlock bootloader = lost DRM key)

If I missed to answer your questions, let me know.

I did not find a version v7 for the 136 firmware on his website.... Do you have a link?

Well, on the Sony website I found a paper that says Sony added security enhancements to the Linux kernel, precisely some kind of runtime control mechanism that is not part of the standard Linux kernel. Thus, there is actually some kernel enhancement by Sony to their Linux kernel. This is why I asked, if DoomLoord uses the Sony kernel source these enhancements will be part of his kernel. If DoomLord does not use the Sony kernel source, these enhancements will not be part of his kernel.

Besides, does it require a kernel change to root a device?

Thank you!
