Prerequisites to Install Paranoid Topaz Android 13 on OnePlus 7/Pro/7T/Pro

The ROM could be installed via two different methods- Fastboot and Recovery [each having its own separate ROM] and we have listed both these methods below. Go through them once and then try out the one that is in sync with your requirement.

Moreover, both these methods will wipe off all the data from your device, so take a complete device backup.

Install Paranoid Topaz on OnePlus 7/Pro/7T/Pro via Fastboot Method

The below instructions are listed under separate sections for ease of understanding. Make sure to follow the same sequence as mentioned.

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 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 process.

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

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 of OnePlus 7 series

STEP 4: Downgrade to Android 11 Firmware

It is recommended that your device should be on the Android 11 firmware before flashing Paranoid Topaz ROM. So refer to our guide on How to Downgrade OnePlus 7/7T/7T Pro Android 12 to Android 11 [3 Methods].

Likewise, rename it to rom, so that the complete name becomes rom.zip.

STEP 6: Boot to Fastboot Mode

Connect your device to the PC via a USB cable. Make sure USB Debugging is enabled.
Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter. This will launch the Command Prompt.
After that, type in the following command in the CMD window to boot your device to Fastboot Mode
```
adb reboot bootloader
```
To verify the Fastboot connection, type in the below command and you should get back the device ID.
