Upgrading Skyzone SKY04X FPV Goggles DVR to 60FPS

The mighty Skyzone SKY04X FPV Goggles is without doubt one of the best analogue goggles out there. However, its DVR recording only supports 30FPS (frame rate). In this tutorial, I will show you how to upgrade it to 60FPS.

This would be the last post I make about the SKY04X, because I have given them away to one of my Patreon followers. Here’s my Patreon if you want to support me also.

Buy Upgrade DVR Module

Unfortunately, this hack is not a simple software upgrade. You need to buy Skyzone’s latest DVR module to replace the existing board. You can get it here:

• For Skyzone SKY04X, SKY04L, Eachine EV300O V2: https://oscarliang.com/product-q0so
• For Skyzone/Eachine Cobra X: https://oscarliang.com/product-7x0f

This DVR board is only compatible with the V2 version of DVR hardware! (Check your hardware version (HW) under firmware version in system menu, if it starts with “V2” then you have V2 hardware. V1 and V3 are not compatible.

Back side of the board.

Taking Apart SKY04X

First of all, remove the receiver module, its covers, SD card, the face plate and headstrap.

There are 3 screws you need to remove, one under the nose, one next to the USB-C port, and one next to the SD card slot.

Then you can wiggle the house very gently and open the housing. Be extremely careful so you don’t put too much stress on the ribbon cables.

Replace DVR Module

The DVR module is the board that has the SD card slot and HDMI port on it. It’s connected to the main board via a ribbon cable, protected by a metal bar. Remove the metal bar with a small screwdriver.

You should also remove the small ribbon cable so it’s easier to work with later on. To do that, simply lift the black locking tab up, and gently pull the cable away from the connector with a tweezer.

Then unplug the old DVR module and put the new one in. Simple as that.

Update SKY04X Firmware

There’s a new firmware you need to flash the SKY04X with, otherwise it won’t recognise the new DVR module.

Before updating, please write down your existing firmware version, so you can check later to see if the update was successful.

You can grab the new firmware on the DVR board product page on Bangggood. It should contain two .bin files (A and B).

1. Connect goggles to the computer via the USB-C port (no need to plug in battery)
2. Hold down the left wheel button, then press the power button
3. A new removable drive should appear on your computer
4. Copy the firmware files (A and B) to the drive, while copying, the goggles will install the update at the same time
5. Once the file copying is done, you can remove the drive and restart your goggles

Now check firmware version to see if it’s been updated.

If all went well, your DVR recording should be 60FPS, as you can see in the file properties.
