# Update PSP to Firmware 6.61

> How to update your PSP to official firmware 6.60 or 6.61 before installing ARK-5.

# Update PSP to Firmware 6.61

ARK-5 requires official firmware 6.61 (6.60 also works). If you are on a lower version, update before proceeding with the [ARK-5 install](/docs/psp/ark-5/install).

Note that other guides may refer to PRO or LME/ME custom firmware. These are older and no longer maintained. Use ARK-5 instead.

## Before you start

There are always risks when modifying firmware. Reduce them by:

- Having at least **80% battery life**
- Making sure your battery cannot fall out during the process
- Keeping the charger plugged in

## Downloads

Download the correct firmware file for your PSP model from [darthsternie.net/psp-firmwares](https://darthsternie.net/psp-firmwares/).

| Model | 6.60 | 6.61 |
|---|---|---|
| PSP 1000, 2000, 3000, Street | Available | Available |
| PSP Go | Available (different file) | Available (different file) |

The PSP Go uses a different update file than all other models. Make sure you download the right one.

## Steps

**1. Rename the firmware file**

If your downloaded file is not named `EBOOT.PBP`, rename it to `EBOOT.PBP`.

**2. Transfer the firmware file**

Connect your PSP via USB or remove the memory card. Copy the file to:

```
PSP/GAME/UPDATE/EBOOT.PBP
```

PSP Go users can place it on internal memory or the memory card.

**3. Launch the update**

Disconnect from USB mode. In the **Game** tab on the XMB, a new icon for the update will appear. Launch it and follow the on-screen instructions. The PSP will restart once the update is complete.

Sony's original update instructions (via Web Archive) describe the same process and show the expected folder structure if you need a reference.

## Next step

Once you are on 6.61, you can proceed with the [ARK-5 install](/docs/psp/ark-5/install).
