Hacking Q3H (allwinner v3 - Camdroid)

For people who have a camera that just has a white screen after removing the new camera from its package or after a bad update, I made a video to try to fix this. Links to tools and drivers files are in the description text of the video.

"How to recover (unbrick) an allwinner v3 4k action camera that has white screen boot"

possibly. other people have used a hex (binary) editor for example IDA Pro to edit files under /system/vendor and /system/lib and supposedly improved video image and sound but I'm not good at doing that yet. ;) Otherwise, please first make a backup of your original firmware by getting ADB drivers and using the script
see - https://dashcamtalk.com/forum/threads/hacking-q3h-allwinner-v3-camdroid.20507/page-11#post-301213
and compare your model and firmware to page 1, post #8 of goprawn
see - https://www.goprawn.com/forum/allwi...mnivision-ov4689-action-cameras?p=130#post130
and if you woud like to, be careful too choose a similar model firmware there, and flash it to see if it would improve anything. Don't worry, the camera can not be "bricked".

Hi all,
I have a Q3H-2 Action Camera acquired from Banggood and I would like to get some better results in video capture.
According to the specifications, it is equipped with Sony IMX179 image sensor and Allwinner V3S processor.
Can I upgrade my camera with your Q3H or F60B flash images firmware (.fex file)?

Meanwhile, I make a firmware backup. It is available for download at:
EDIT:

okay. i downloaded your firm and NMD firm. yours is "fuxin4k30imx179s_sdv-eng 4.2.2 JDQ39 eng.fjj.20160621.113349" with imx179S sensor chip, but NMD is "fuxin4k30imx179_sdv-eng 4.2.2 JDQ39 eng.fjj.20160509.180916" with imx179 (not S) sensor chip. your camera probably needs a "imx179S.ko" file but it is missing from NMD firmware (2-system.img). this is likely the cause of the camera stuck on white screen. try to flash your backup firm file or flash a firm copy from https://drive.google.com/file/d/0B4tyaJWIqCb_eDRTQjRweFRVcEE/view [2016-06-21 (shows 20160621V03)]. plz try to follow the video. buena suerte :)

The problem is when i connect the camera to pc , didnt recognize as usb and i cant put that file because i cant go in to my sd card or menu from camera "stuck in snowboarder logo" , my english is bad and maybe i dont know what are you saying , thanks :)

BTW: i check the video and i see my blue led turns off 2 sec a go when i turn on the camera and show the logo.

okay. do not use sdcard, and do not use battery -- remove (take out) sdcard and battery. disconnect (unhook) usb cable. hold ↑↑ UP button on camera. connect USB cable. download (descarger) files:

When you turn on the camera and press 'UP', you are entering the camera's recovery mode. Update your drivers to F60B_recovery_driver. Then try to follow the steps provided by Petesimon in the youtube video. Download makeimg scripts and PhoenixSuit. Use your original full_img.fex and makeimg scripts to create a .img image file. Now flash your camera with PhoenixSuit using this .img file.

I've been to confirm, my original firmware does not have the module imx179s.ko. You can use squashfs_unmake script to extract the contents of my 2-system.img. Copy your imx179s.ko module to vendor\modules\ and re-compress the 2-system.img file using squashfs_unmake script. You should also replace the script.bin info using scriptbin_read and scriptbin_write scripts. All those tools are available at:



Cuando enciendes la cámara y pulse 'ARRIBA', tu cámara entrará en modo de recuperación. Actualiza los drivers para F60B_recovery_driver. Después, intenta seguir los pasos indicados por Petesimon en el video de youtube. Descarga script makeimg y PhoenixSuit. Utilice lo arquivo full_img.fex originale y lo script makeimg para crear un archivo de imagen .img. Ahora actualiza tu cámara con PhoenixSuit usando este archivo .img.

Ha confirmado, mi firmware original no tiene el módulo imx179s.ko. Porsupuesto, puedes utilizar los scripts squashfs_unmake para extraer el contenido de mi 2-system.img. Copia el módulo de imx179s.ko para vendor\modules\ y volve a comprimir el archivo 2-system.img usando lo script squashfs_unmake. También debes reemplazar la información de script.bin mediante los scriptbin_read y scriptbin_write. Todas estas herramientas están disponibles en:

Have you selected the fw file on Phoenix before connecting the camera?
I think it's normal your PC recognize your camera as a USB device(VID_1f3a_PID_efe8).
