There’s no better way to cement this statement than by looking at the fact that the Xperia 1 III has already been blessed with quite a few custom ROMs based on the latest Android 13 builds. These include the likes of Rice Droid, SparkOS, and the ever-so-popular LineageOS. And in this guide, we will show you the steps to welcome abode these ROMs onto your device. So without further ado, let’s get started.
Prerequisites to Installing Android 13 Custom ROMs on Xperia 1 III
Irrespective of the ROM you flash, the process will wipe off all the data on your device. So please take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.
STEP 1: Install Android SDK
First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform tools folder, which will be used throughout this guide.
STEP 2: Enable USB Debugging and OEM Unlocking
Next up, you will also have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader unlocking. So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
STEP 3: Unlock Bootloader on Sony Xperia 1 III
Next up, you will also have to unlock the device’s bootloader. Do keep in mind that doing so will wipe off all the data from your device and could nullify its warranty as well. So if that’s all well and good, then please refer to our detailed guide on How to Unlock Bootloader on any Sony Xperia Device. Once done, don’t restore the backup now as we will have to again format the device in the subsequent steps.
STEP 4: Download LineageOS 20 ROM for Sony Xperia 1 III
STEP 5: Boot Sony Xperia 1 III to Fastboot Mode
