*/Finally I managed to build mount namespace enabled(required by MagiskHide) kernel for Sony Xperia M2.
I applied patch to the original kernel source code(available on Sony website), version 3.40(18.6.A.0.182)
So you don't need kernel 3.8+ for using MagiskHide
This kernel tested on D2302 device.
Kernel:
3.40 - 18.6.A.0.182
Features:
- mount namespace(required by MagiskHide)
- kernel configuration is available in /proc/config.gz
- boot image format is AOSP, so there is no need to use Boot Bridge for flashing Magisk
Tools:
- Ubuntu 14.04
- gcc 4.7
- mkqcdtbootimg (for building flashable boot image)
- Flashtool 0.9.11.0 (for extracting kernel.elf from original .FTF)
- Android Image Kitchen 3.6 (for extracting ramdisk and cmdline from original kernel image)
- TWRP 3.1.0-0
- Magisk 20.3 (20300)
- Magisk Manager 7.5.1 (267)
Download:
DM2-V0100-D2302-boot.img
Installation:
- Ensure device ROM version is 18.6.A.0.182 or based on that or has same working kernel
- Download .img file
- Power off device
- Press Vol+
- Hold Vol+ and connect device to your computer using USB cable
- Device will boot in fastboot mode(verify that notification light color is blue)
- run "fastboot devices" to ensure device is connected (fastboot print device serial number)
- run "fastboot flash boot DM2-V0100-D2302-boot.img"
- Ensure no error is occured during flash
- run "fastboot reboot" to restarting device
- After boot up check kernel version in Setting->About
- Magisk can be flashed using TWRP
If MagsikHide not worked :
- turn off and then on again MagiskHide in MagiskManager->Seetings
- Hide Magisk Manager using "Magisk Manager->Settings->Hide Magisk Manager"
If you encounter bootloop or other kernel related problem:
- Don't worry
- Download original ROM 18.6.A.0.182 using XperiFirm or newer version of Flashtool bundled with XperiFirm
- Install and Run Flashtool 0.9.11.0+(I used 0.9.11.0 version)
- Click on "Flash Device" button in toolbar
- Select "Flashmode" in "Bootmode chooser" window
- Select downloaded ROM in left panel
- Exclude eveything in right panel except KERNEL
- Uncheck all WIPE options
- Don't change other settings
- Click "Flash" button and follow flash process
