Unknown Allwinner cam - changing picture modes somehow possible?

[foobar]

Hi,

I recently bought an 25€ Action Cam. It seems to work nicely, but I miss the feature where it takes continously photos every 1 or 3 seconds.
There is a timer function which takes pictures in 3 s but just one.

The camera is labeled as Fontastic AC4K, Fontastic seems to be a brand of D-Parts[1]
So I played a bit with the buttons a figured out there is a bootloader. When in bootloader mode
it says it is this USB device

vendorId 1f3a, idProduct=efe8

which seems to indicate an Allwinner device in FEL[0] mode.

In the normal operation menu it says:

Model: ActionCam
Version: 20180322V3.3
Rev. 20180322
Manufacturer: Fontastic

When I connect it to my computer in charging mode it is an Android device

1f3a:1002 Onda (unverified)

Can somebody point me in the right direction where to look to change the software to take continously photos?
Or is there some firmware which does that and runs on this cam?

Thanks a lot.

nice info!
FIRST, make a backup copy of your firmware, and share it here. follow this tutorial video https://youtu.be/QrhPxpFFMrc?t=1

the original firmware in a camera tells us what other firmware might be compatible...

after that, we can try to find a firmware that fits your cam.

Thanks petesimon.

I uploaded the backup.zip and script.bin to the dropbox folder.

As I did not have no dd on my cam I had to cheat with using busybox (https://busybox.net/downloads/binari...busybox-armv6l) and tweak a little bit the OS X script.

i like your adb command "adb devices -l" and thanks for the files. here is your FW https://www.dropbox.com/s/2cmzapnr7h...ackup.zip?dl=0

Will do, but have bricked my camera and need to bring it back to live. So it takes some time.

btw. how to read the script.bin file? is there a tool for that?

[petesimon]

get and unpack this zip file. https://www.dropbox.com/s/vf22hrxggl...ll_fw.zip?dl=0
put your script.bin and full_img.fex into the same folder where the scripts are.
read the "readme-small_fw.txt" file inside the zip archive

run these scripts in the order shown:
unfex.bat
scriptbin_read.bat
convertscriptbin.bat -- you will need Java installed
squashfs_unmake.bat
fwinfo.bat
getfwinfo.bat

and open "script.fex" file in a text editor.

your camera "product" vanci1gddr is unique as far as I know. you can look for other firmware in the big big thread on page 1 in post #8, and look in pages 38 in reverse order (38, 37, 36, etc) for other firmware. Be sure to match sensor, LCD, and full_img.fex file size 8126464 bytes.

thanks to nutsey, i modified the unfex-refex scripts to work with 8126464 bytes full_img.fex
download here - https://www.dropbox.com/s/6n6f4i8r3u...26464.zip?dl=0

These firmware sizes /8 1.. ... byte/ squashfs_unmake.bat are not packaged, "Can't find a SQUASHFS superblock on c:\unfex-scripts......\UNFEX\2-system.img" error messages are sent.
It would be nice to have solution for 32bit Xp

[petesimon]

what is the size of your full_img.fex firmware file?

give me more details about the problem.... give me screenshots and more error messages

are you using NTFS file system on your computer hard drive?

[petesimon]

thanks to nutsey, i modified the unfex-refex scripts to work with 8126464 bytes full_img.fex
download here - https://www.dropbox.com/s/6n6f4i8r3u...26464.zip?dl=0

[tvszer]

The size of the full_img.fex 8159232 byte.
I use NTFS file system.
It's about this firmware. I can't unpack 2-system.img.

I'll let you know from the beginning briefly that I was going. I bought a camera sold under the name "F60R", which does not have the inside, it is equipped with 1GB of DDR RAM, I think, only 8MB of firmware can be good for it. Unfortunately, the original firmware could not be saved, but a non-vertex was fired, so it became a brick. This firmware is almost good for just GC9305 LCD, mine is ST7789V. I switched the driver in script.bin, now there is a picture on the LCD but inversed. That's why I think 2-system.img should be modified, but I do not know. I do not even know what to change. Also, it does not work with a remote control, and I also want to improve the audio quality of recording because I need great sound quality. I would be very happy if you could help them. Thanks!
