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.
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.
To make things clear: There are 3 versions of mainboard in this googles: v1, v2 and v3 (this upgrade works on for v2) Googles it self are in 2 versions v1 – 30 fps dvr v2 – 60 fps dvr
So if you have a v1 googles and v2 board this product is for you.
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.
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.
Hello, 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.

To make things clear:
There are 3 versions of mainboard in this googles:
v1, v2 and v3 (this upgrade works on for v2)
Googles it self are in 2 versions
v1 – 30 fps dvr
v2 – 60 fps dvr
So if you have a v1 googles and v2 board this product is for you.
Oscar why you don’t disconnect ribbon cable from DVR module side ? looks like its much easier to do, does those cable are diferent ?
I just upgraded DVR on my goggles – disconnect cable from module side – no problem, works perfect.
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?
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?
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?
The DVR playback doesn’t work through AV output to an external screen
Hello,
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.
theres no fle in the zip folder of EV300O firmware!!! Please help me!
Maybe you should mention that the V2 version already has the 60fps board.
Any chance this would work on an 03O as well! ?
