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.

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:

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.

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.

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

Upgrade Skyzone Sky04x Dvr 60fps Remove Old Module Board 2 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.

the skyzone download for the v2 DVR is not 2 bin files, but a rootfs.jffs2 file. can anyone tell me how to update using that file type?

Craig 24th April 2024 - 8:19 am

This old so you’ve probably sorted it, but the procedure is in the manual.
Put the .jffs2 file on your SD card, put that in the DVR slot, then go to “DVR FW upgrade” as shown in the last screenshot, ON, click, wait.

I have a set of Skyzone 04X V1. Will this work on the V1 goggles? My DVR displays a “Error” and will not record. Does this unit replace the V1 unit?

It’s best to contact Skyzone customer service to troubleshoot what’s wrong with your DVR first, then ask them if the upgrade DVR board can fix it. They are pretty responsive.

I also bought this for my V1 goggles and have the same problem. Maybe you should mention it so more people don’t buy this thinking it will work for the V1. Thanks.

Hi there, Tim
Could you fix the issue of the ERR? Today this same issue started to happen to my sky04x V1 too.
Best regards

I know this question is not about current topic but may be somebody know marking of diode which placed on the other pcb side behind power connector?

Juan C. Gonzalez 28th January 2022 - 8:05 pm

About to follow your procedure. Thanks for writing this Oscar!

There is a V3 version of the firmware on the SKYZONE website. what is that for? Is there a newer V3 version of this DVR module?

Robert 18th November 2021 - 7:52 am

The DVR playback doesn’t work through AV output to an external screen

Roman 26th October 2021 - 12:31 pm

I have Cobra X v.1 glasses does it make sense to go for that upgrade? Does upgrading even lost images? I have noticed that when playing FPV video, the image is sometimes skipped. Thank you.

Feliciano Crecca 22nd October 2021 - 7:07 pm

theres no fle in the zip folder of EV300O firmware!!! Please help me!

Quentin 12th October 2021 - 8:01 am

Maybe you should mention that the V2 version already has the 60fps board.

Hnbc2 9th October 2021 - 6:20 pm

Any chance this would work on an 03O as well! ?
