Android 10 comes earlier than expected, but there's no twrp to flash Magisk to gain root access. I tried to use SAR method to patch boot image, and it actually worked:

Requirements:

A PC with ADB environment setup. * If you are using macOS, try to use a Virtual machine instead.

XperiFirm to download Android 10 firmware.

Magisk Manager App.

unsin.exe program to extract sin file.

Download here.

Instructions:

1. download the latest Android 10 firmware from XperiFirm, the current one is 52.1.A.0.532

2. open the downloaded folder and find boot_X-FLASH-ALL-B6B5.sin file. it may vary on XZ2C, but it surely will start with `boot_X-FLASH-ALL` .

3. drag the boot_X-FLASH-ALL-B6B5.sin file over unsin.exe to extract boot image, then you will get boot_X-FLASH-ALL-B6B5.img in the same directory.

4. Copy boot_X-FLASH-ALL-B6B5.img into your phone.

5. Install Magisk manager app, and make sure your phone is connected to the internet

6. Press Install → Install → Select and Patch a File, and select boot_X-FLASH-ALL-B6B5.img

7. Copy the patched image from your device to your PC, then flash it with fastboot command:

Code:

fastboot flash boot_a magisk_patched.img
fastboot flash boot_b magisk_patched.img

fastboot reboot

after reboot the devices, your XZ2 is should be rooted, but it probably not pass SafetyNet Check, you can use MagiskHide Props Config Module to fix it.

I can't find the way to leave the boot image and patched boot image down below as the attachments, but even if I did, I still suggest to do it manually, just in case I am an idiot and it might broke your phone.
