With the phablet UI making a mark on many devices with Paranoid Android ROM, it’s time for the Xperia Arc to join in on the fun. Paranoid Android features a phone and tablet hybrid UI that makes efficient use of the screen for displaying more info on the screen, also allowing to scale and size different apps and parts of the interface individually as well as use them in phone, phablet or tablet mode as you prefer.
You also get the latest version of Android – Android 4.1 Jelly Bean – with Paranoid Android ROM. Jelly Bean brings many new features to Android, such as a smooth as butter and fluid interface, expandable and actionable notifications, smart and highly accurate keyboard, faster and efficient browser, a voice recognition assisted Google search experience, offline voice typing, and lots more. Keep in mind that this is an unofficial custom ROM and is currently under development, so there may be a few issues present and some things might not work properly.

This ROM and the guide below are compatible only and only with the Sony Xperia Arc, model number LT15i. It’s not compatible with any other device and may render an incompatible device unusable. Check your device model in Settings » About phone.

How to Install Paranoid Android ROM on Xperia Arc

Important! Don’t forget to at least make a backup of your APN settings, which you can restore later if your data connection does not work after installing the ROM. Use the backup guide to find out how.
- Important! Your Xperia Arc must have an unlocked bootloader. You can unlock your bootloader officially → here. Unlocking bootloader voids your warranty, so make sure you have no problems with before proceeding.

- Transfer the 2 zip files downloaded in step 4 and 5 to the SD card on your phone.
- Open the downloaded zip file of the ROM and extract the boot.img file from inside it (use a software like WinZip or 7-zip to extract). The boot.img is the kernel that needs to be flashed along with the ROM.
- Download fastboot, which will be used to flash the boot.img obtained in step 7.

To do this, first plug the USB cable to PC, then pick up your phone and hold the Menu key (key at the bottom right on your Arc), and then, while holding the Menu key, connect the USB cable to your phone. The LED should light up on the phone to indicate it is connected in fastboot mode.

- Now, in Command Prompt, type the following commands to flash the kernel, pressing Enter after each command:
- cd c:\Fastboot
- fastboot flash boot boot.img
NOTE: If you get a “waiting for device” message with the above command, type fastboot -i 0x0fce flash boot boot.img to flash the kernel.
- Once the kernel is flashed, you will get a “finished”/OKAY message in the command prompt window. Disconnect the phone from your computer. It will now be turned off automatically.
- Turn on the phone. The screen will turn on and show you the kernel logo. As soon as the blue LED lights up, start pressing the Back button on your phone continuously until you boot into recovery.
In recovery, use Volume buttons to navigate and Home button to select options.
