[ROOT][Kernel][TWRP][DRM] repack of stock kernel with dm-verity & SONY RIC off

[zacharias.maladroit]

Hi guys,

are you aware that by following:

[ROOT][Kernel][TWRP] repack of the stock kernel with dm-verity and SONY RIC off

you'll get a repackaged stock kernel that

• has potentially root (option)
• a recovery TWRP to which you can boot via volume key combination during boot (didn't read about it for Xperia M4 Aqua yet, but on Z5 it works),
• dm-verity & Sony RIC DISABLED (additional security which messes with rooting and modifying /system - thus needs to be disabled, also leads to non-booting phone when system is modified)
• DRM emulated (restored) so that camera quality is same like before bootloader unlock, picture/image enhancement working (BRAVIA/XREALITY engine)

@madsin has followed the steps and supposedly was successful:

@AndyPhoenix9879 is your custom kernel using a repackaged stock ramdisk with the drm emulation ? https://forum.xda-developers.com/m4-aqua/development/kernel-sky-melon-t3532944
@dani020110 the same question to you: is your custom kernel using a repackaged stock ramdisk with drm emulation ? https://forum.xda-developers.com/m4-aqua/development/kernel-foykernel-t3536004

I'm posting this here since I'm not sure yet if I'll unlock bootloader & lose the TA partition data/keys

or I should flash back to Lollipop, root (with locked bootloader), backup the keys, then unlock the bootloaders [for my Z5 that option wasn't available at the time to backup & restore the keys]

What you've just posted is used on both kernels. It works on MM even with stock kernel but the recovery and xposed option doesn't. I haven't tried backing up the keys with MM since there is no root but I've used the second method and it works.

Hi there! It's really nice to see you here!
1. Yeah I'm using that tool to get root access
2. I tried that recovery, but it wasn't working correctly
3. As far as I know, we don't have that kind of security here, we can modify /system flawlessly without using that option
4. I haven't tried that drm restoration yet, because I thought it wouldn't work
Anyway this is the ramdisk I'm using https://github.com/dani020110/destiny_build_tools/commits/master/ramdisk

When I was at lollipop I did that trick to backup my drm keys, and then unlocked my bootloader
Anyway you can try the universal dirty cow one

@DavidMKD , @dani020110

thanks for the quick and in-depth answers !
@dani020110 thanks for the warm welcome

okay, I'll see how the dirtycow approach works out

sorry, I've used up all "thanks" for today, will give upon next chance

Yes, it's awesome that we have those great devs/minds at XDA who empower us,

[much thanks to @tobias.waldvogel ]

otherwise we would lose important features and had to do compromises

when in fact we root and unlock the bootloader to have *more* features in first place !
