While the Sony Xperia XA1 (released in 2017) was a popular mid-range device, finding a dedicated "interesting review" for a custom ROM today is a bit like hunting for vintage car parts. Because the device uses a MediaTek Helio P20 chipset—rather than the more developer-friendly Qualcomm Snapdragon—the custom ROM scene for it has always been significantly more limited than its siblings.

If you are looking to breathe new life into an XA1, here is the current consensus and "real-world" review of the custom ROM experience: The "State of the ROM" Review

The MediaTek Hurdle: Most reviewers and users on the Sony XDA Forums note that the lack of public source code for MediaTek processors makes creating stable, bug-free ROMs difficult.

LineageOS Availability: There have been community builds of LineageOS (and even experimental "Oreo Go" editions) for the XA1 family. Users generally report that these ROMs offer a much cleaner, faster UI than Sony's original skin, which was known for occasional multitasking lag.

The "Camera Trade-off": A common "review" warning for any Sony custom ROM is the loss of the TA Partition. Unlocking the bootloader can permanently delete proprietary Sony camera algorithms, which may result in noisier low-light photos—a significant downside given the XA1's 23MP sensor was its standout feature.

Performance Gains: For users dealing with a slow device on official Android 8.0 Oreo, a "debloated" custom ROM is often reviewed as a "must-have" to keep the 3GB of RAM and Helio P20 usable for modern apps. Where to Find More

For the most authentic "user reviews" and step-by-step guides, the community continues to point toward these hubs: Installation Process Review Installing a ROM on the

XDA Forums: The Xperia XA1 ROMs, Kernels, and Recoveries section is the only place to find vetted, community-tested files.

Reddit: The r/SonyXperia community often discusses the long-term viability of rooting older XA series phones to fix battery drain and speed issues.

Installation Process Review

Installing a ROM on the Sony XA1 is moderate to difficult.

  1. Unlocking Bootloader: Sony provides official bootloader unlocking codes. You have to request it from the Sony developer website. This process wipes your DRM keys.
    • Warning: Once you unlock the bootloader, your camera quality will decrease significantly, and features like X-Reality engine will vanish forever (unless you backup the TA partition, which is risky).
  2. TWRP: You need a custom recovery (TWRP). However, TWRP for the XA1 often requires a "boot-to-recovery" method where you flash the recovery image to the boot partition temporarily, which can be confusing for beginners.
  3. Bug susceptibility: Because many ROMs are ports from the XZ2, you have to be very careful about flashing the correct vendor files. Flashing the wrong vendor can hard-brick the device.

The Catch: Known Limitations on XA1 Custom ROMs

Before diving in, be honest about the drawbacks:

1. Android Version Updates

The XA1 officially stopped at Android 8.0 Oreo. With custom ROMs, you can jump to Android 10, 11, 12, or even 13. This means new emojis, better notifications, privacy dashboards, and Material You theming.

Can I relock bootloader after installing a custom ROM?

Not recommended – may brick the device.

Should You Do It? Final Verdict

The Sony Xperia XA1 custom ROM scene is not for the faint of heart. The MediaTek chipset makes development harder than Snapdragon devices. You will lose the signature 23MP camera magic and DRM keys.

However, if your XA1 currently sits in a drawer because it’s too slow to run modern apps, a custom ROM is a resurrection. LineageOS 20 transforms the device into a respectable media player, backup phone, or even a primary device for a light user.

Final Recommendation: Flash LineageOS 20. Keep your expectations realistic. Enjoy security patches from 2025 on a phone from 2017. That is the magic of Android.
