Campark X20

[Epoch555]

Hi, are there any hacks for the X20? Can I use autoexec.ash or a tool like the yimax-pro script or something similar to improve video quality?

Hello, this cam seems the same as Andoer AN2 and RUISVIN S30A WiFi Action Camera

I updated the firmware from campark website and now my camera is broken, the screen shows (as video feed) some random colored dots while touch screen and icons etc are all ok (even the menu works)

[nutsey]

Which one is yours? X20, AN2 or S30A?

[dorubrad]

[dorubrad]

I have the x20

[nutsey]

Ok. Seems like your cam has the Panasonic MN34110 inside and you've flashed it with a Sony IMX078 firmware...

[dorubrad]

Hmm, I used the firmware from the website (the one and actually only I can download)

is there some firmware that might work ?

[dorubrad]

The strange thing is:

1. The formware was from their website and should be the official one
2. As USB storage the camera was showing "novatek" as name

[nutsey]

I can remember several similar situations with Chinese action cam brands when some hardware specs for an actual product were changed without any notice...

[dorubrad]

Product ID: 0x8612
Vendor ID: 0x0603 (Novatek Microelectronics Corp.)
Version: 0.10
Speed: Up to 480 Mb/sec
Manufacturer: NOVATEK
Location ID: 0xfa130000 / 2
Current Available (mA): 500

Extra Operating Current (mA): 0


This is what I get when connected via usb

Here it states: 4K/20MP & SONY Sensor

- is there a similar camera with these specs to try the firmware?

[dorubrad]

They "updated" the update wit a fix ad emailed it to me

It is attached fo any other person that has the Campark X20 Touchscreen 20MP 4k version (dual screen)

IT FIXED MY CAMERA!

!!!! USE ON YOUR OWN RISK !!!!

Thanx for sharing! I was right that the sensor is different, but I was wrong about the model. Your cam has the Omnivision OV4689 inside. Better low-light performance, but lower resolution comparing to the Sony IMX078.

[dorubrad]

Well at least if I found the solution for me it is nice to share, after all they should put it on their website ...

Help me please, hi I have a camprak x20 with the firmware locked, can you send me the original firmware to unlock the cam? Thanks.

Hi, I am now stacking the same problem.
After I update the firmware, my campark x20 camera can't get image from the sensor. setup screen and menu works correctly.

Do someone have other firmwares? I sent an email to the customer support, but they said that they only have the latest one.

And I also test the firmware they sent, but nothing was shown on the screen.

I think they stopped the publish of firmware. Now I can't access to the firmware page: https://www.campark.net/pages/firmware
Please help me.

[nutsey]

Could you share those firmwares?

[nittax]

This is the firmware the customer support sent to me.

[nutsey]

What was your original fw version? X20, X20-1 or X20-2?

[nittax]

The information of my original firmware version is the following. (At that time all camera function worked correctly. I forgot to backup
Model X20
Version V1.0
Update Date 09 05 2017

So my camera model is X20? (I'm not sure)

[nutsey]

Yes, yours is X20 with IMX078 inside. X20-1 uses OV4689, X20-2 - GC13503.

BTW, seems like Campark recently changed hardware platform for the X20. I'd say it looks like a HiSilicon chipset.

[nittax]

Thank you for the information.
I bought this X20 camera February 2018.
My camera is old, so the chipset seems to be based on novatek.
And I tried the firmware dorubrad shared on this page above, but my camera can't get image from sensor..

[nutsey]

Try this one: https://mega.nz/#!zrhmTC5K!sgudmw_TJ...qjGK-xM7juDpYY

[nittax]

Thanks a lot !!
Now my camera works correctly...!
Thanks.

BTW, do you collect many firmware of many various chinese action camera?

[nutsey]

Yes I do. I've got almost 2TB of firmwares, manuals, datasheets, teardown pics and so on.

[nittax]

I see... anyway, I appreciate you a lot.
The customer support should publish their firmware...

[nutsey]

I don't think they know so much tech details about their cams

[nutsey]

BTW my collection was not downloaded from somewhere in a blink. I've spent 5+ years for precise bit by bit explorations to get all the data I've got.

Hi, sorry to jump on this post.

Just new member never done this before.

I'm having issues with my campark x20 and have done since I bought it from amazon, I missed the date to send back and the support wasn't very helpful. I have been unable to use the camera to it's full potential since.

When in any other mode other than wide it does not save the photo correctly if I zoom in change the picture quality anything it will not save the photo other than a blue fuzzy screen.

I have attached photos of my camera version and what I mean by fuzzy photos.

Campark x20 - 20
Using sandisk extreme 64gb memory card.

I'm unsure if I have to update firmware or what I have to do but any help will be really appreciated as I have had the camera since April and only ever been able to use wide mode.

Thanks Steven.
