I normally build roms for Oneplus devices, but one of Xperia users donated and asked to build for Xperia XA2 Ultra. XA2 Ultra doesn't have a lot of options, so, here it is:

I have been building Android roms since 2012 for various devices including multiple Sonys, Lenovo Zuk, Oneplus 3, Oneplus 5, 6, 8 and 9. You can check my Oneplus 6 or Oneplus 6T or Oneplus 8 threads and browse my profile.

Jaguar rom is focused on hardening of AndroidOS and kernel. As such, the rom has hardened bionic, art, framework and tightened security.

1 Rom control with custom Power options, Statusbar, Buttons, Navbar, Quicksettings, Lockscreen, Notifications, Gestures, Themes etc...

2. Heavily modified Art, Bionic System/Vold and System/Security

3. Telephony response to Type Zero sms ('silently acknowledged') disabled

4. Toggle to disable Captive Portal logging.

5. Speakerphone proximity sensor toggle - could be set to automatically switch to speaker when not at the ear

6. IMEI and phone numbers hidden in About menu

7. Built-in encrypted DNS providers, such as: Cloudflare (US); LibreDns (Germany); AdguardDns (Cyprus); and PowerDns (Netherlands)

8. Wakelock and Alarmblocker

9. Fully working Call recording with the button visible in Dialer

10. Deskclock app modified to work with PowerOn alarm. The app will boot the phone 2 minutes before scheduled time to trigger the alarm on time

11. Default Dark mode

12. All regular customizations plus. You tell me which feature is missing.

The rom has 2 versions Vanilla (no Gapps) and Full. So, pick according to your needs.

Install instructions

Xperia AX2 Ultra is somewhat easier to deal with (because it doesn't have virtual partitions). So, the only requirement is to be on the latest stock firmware in both slots, and unlocked bootloader, of course. If you have been using Lineageos 18-19, you already have it. If not, install stock and then use Lineage's copy-partitions zip to populate another slot.

1. Either boot official TWRP and flash the rom followed by factory reset, or boot my recovery and sideload the rom also followed by factory reset.:

The command to boot recovery (from fastboot) is simple:

fastboot boot 'recovery name' (without quotes).

The first boot might take longer, because your phone will be encrypted.

2. Magisk: only versions 24.3 and higher will pass Safetynet. However, don't use TWRP, or any other recovery, because you won't boot. Rather install Magisk as a regular app, take boot.img I provide (the same as recovery), put it on your internal storage and patch from the app. Then install the new image (Magisk will tell you where it would save it) via fastboot: fastboot flash boot boot.img.
