How to identify this camera?

[dtralara]

Good evening,

I don't know how to identify this camera [1]. Anyone knows what it can be?
The menus look quite like a few screenshots of eken clones I've seen around here [2].

The 'firmware information' entry of the menu reads:

Model:
Version:    20180903V25
Updated:    20180903
Manufacturer:

Also, the 'dd' command is missing from the system (via 'adb shell'). I get the error message:

/system/bin/sh: dd: not found

Because of that I'm having trouble backing up / copying the firmware on an sdcard.
Does anyone know any workaround? (I'm on Linux)

Thanks

there are too many "eken clones" to pinpoint which camera you have. so, what eken clones are you talking about ?
please power on the camera, take photos of the front, and top and rear of the camera and post the photos here.

Thank you for your assistance.


Attached are photos of the camera and of its menus:

awesome. it's very helpful. evidently you have an Allwinner V3(s) camera. thanks.

PS: I can't manage to backup the firmware since the dd command is not available...

[email protected]:/ # dd if=/dev/block/mtdblock0 of=/mnt/extsd/backup/0-uboot.img
/system/bin/sh: dd: not found

Isn't that strange ?

[petesimon]

busybox works in the camera. 'dd' command is inside busybox. download the "busybox-armv7l" binary from https://busybox.net/downloads/binaries/1.21.1/ and copy it to the root folder of the camera using adb push and do the 'dd' command that you want.

adb kill-server
adb root
adb remount
adb push busybox-armv7l /busybox
adb shell
chmod 755 /busybox
/busybox dd if=/dev/block/mtdblock0 of=/mnt/extsd/backup/0-uboot.img

continue to use /busybox dd to backup other mtdblock's
.
you could also watch this video https://youtu.be/QrhPxpFFMrc and use the "backup2.cmd" script http://bit.ly/AllwinnerV3FirmwareBackupScript

Can you check if the /bin/toolbox is available?

[dtralara]

Yes. There is!

[email protected]:/ # toolbox                                                      
Toolbox!

So 'toolbox dd' should do the work then, right ?

PS: There's a kernel loaded module named imx179v. Am I right in thinking that it's an Allwinner system with a imx179 Sony sensor ?

Here's a link to the firmware:
https://drive.google.com/open?id=1UBaVQQVsIvYQSd4E-DE9imczGKvibYsW

I couldn't make the fwinfo script work so I ended up gathering the firmware information manually.
To do this, I just mounted the system.img image file as a loop device and then sifted through the relevant files (build.prop, /etc/MiniGUI.cfg, /etc/info.xml ... )

sudo mount -o loop -t squashfs 2-system.img system

Firmware information (Warning - manually compiled):

Product:       fx1gddrimx179vpq-sdv
Manufacturer:  lzm
Short id:      fuxin
OEM id:        zhongxing_ir
Camera type:   fx2830
FW orig. date:
FW mod. date:  20171012
FW date: 
Camera name:
Version:        20180903V25
LCD model:
LCD resolution: 220x176
LCD count:    1
Sensor model: imx179s

I hope I'm not mistaken.

Thanks for sharing your info! Please also share all 0/1/2/3/4/5/6 small "img" files.
working link for full_img.fex - https://drive.google.com/file/d/1UBa...zGKvibYsW/view
I'm not able to unpack the 2-system.img either. The full_img.fex firmware size is 8126464 bytes and its structure is different than other 'fex files. However, I was able to get text from script.bin (script.fex). Here is additional info:

LCD model: ili9225
Sensor: imx179v

thanks to nutsey, i modified the unfex-refex scripts to work with 8126464 bytes full_img.fex
