The below 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 Nothing Phone 1

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 Nothing Phone 1.

You can now grab hold of the desired custom ROM for your device from below

Once downloaded, rename the ROM file to rom.zip and the recovery to boot.img.
Then transfer both these files to the platform-tools folder on your PC.

STEP 5: Boot to Fastboot Mode

Now connect your device to the PC via 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.
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.
```
fastboot devices
```
If you don’t get any serial ID, then please install Fastboot Drivers on your PC.

STEP 6: Flash LineageOS Recovery and Vendor_boot

First off, type in the below command to flash the vendor_boot
```
fastboot flash vendor_boot vendor_boot.img
```
Now, use the below command to flash the LineageOS Recovery:
```
fastboot flash boot boot.img
```
Then use the below command to boot your device to Recovery
```
fastboot reboot recovery
```

STEP 7: Factory Reset Device

From the LineageOS Recovery, go to Factory Reset.
Then select Format Data/Factory Reset > Format Data.
Your device will now undergo a reset.
Once done, you shall get the “Data wipe complete” message.

STEP 8: Install LineageOS Android 13 ROM on Nothing Phone 1

From the LineageOS Recovery, go to Apply Update > Apply from ADB.
Then head over to the platform-tools folder, type in CMD in the address bar, and hit Enter.
This will launch the Command Prompt. So type in the below command to flash the ROM file via Sideload:
```
adb sideload rom.zip
```
The process will now begin and once done, you shall get the Total xfer: 1.00x message [Got an error? See FAQ below].
If you want to install GApps, then move over to the next step otherwise select Reboot System Now to boot to the OS.

STEP 9: Install GApps on Nothing Phone 1 [Optional]

Go to Advanced > Reboot to Recovery. Your device will reboot to LineageOS Recovery.
Once done, go to Apply Update > Apply from ADB.
Now type in the below command to flash the GApps file via Sideload:
```
adb sideload gapps.zip
```
You will get a Signature Verification failed message because the GApps package isn’t signed by LineageOS. That’s not an issue, just hit YES to proceed ahead.
Once done, you may now finally reboot your device to the OS via “Reboot system now”.

That’s it. These were the steps to install the LineageOS ROM based on Android 13 onto your Nothing Phone 1.
