Introduction
Installation instructions
Now use the TWRP install feature to install dual-boot.zip. Follow the prompts of the Aroma graphical installer.
CAVEAT: this extends the boot time by about 5 - 10 seconds as ramdisk images need to be unpacked and there's a wait on a keypress to determine whether to enter recovery mode. In order to boot into recovery, press power on. When you see the yellow LED come on then press the down volume button once or twice. You will then boot into TWRP.
NOTE: the dual-boot.zip installs a new 28.0.A.8.251 kernel. If you're using the autoroot kernel from Devries you will need to flash SuperSU to re-root your device
This dual boot/recovery works by flashing the recovery image to the FOTAkernel partition. A custom ramdisk image contains the normal boot image. If the down volume keypress is detected, then the recovery ramdisk is automatically extracted from the FOTAKernel partition and flow of control switches to recovery. If no keypress is detected then the normal ramdisk is extracted and normal android boot ensues.
Those of you who installed version 1.0 please download and install this version 1.1 to fix the error with the startup of the trim area daemon

Disclaimer: While this TWRP has been tested by myself on my own device to flash, wipe and backup, I make no warranties as to it's performance. Use at your own risk.
WARNING: flashable version contains a kernel boot image which will be flashed to your device along with the recovery image.
Installation instructions
- This recovery image is for the E6553 single SIM Z3+. Do not use it on another model.
- This recovery image requires an unlocked bootloader. You will lose some functionality on your phone if you unlock your bootloader
- Do your research and make sure you're using the latest version of the relevant tools if you do decide to unlock.
- DO NOT enable MyXperia functionality if you've unlocked your bootloader. You will brick your device.
- This first download of this recovery image CANNOT be flashed to your phone and must be used in fastboot mode only
- The second download is a flashable recovery
- Use the first version to flash the second dual-boot.zip version
- Unzip the recovery.zip file to extract the recovery.img file to use in fastboot mode
Code:C:\>adb reboot bootloader C:\>fastboot boot recovery.img C:\>adb push dual-boot.zip /sdcard/dual-boot.zip C:\>adb push dual-boot.zip.md5 /sdcard/dual-boot.zip.md5
