flashed my allwinner v3 OV4689 but now no display, is there a way out (have a backup)

[ostearn]

It 'updated' the firmware just fine, but now I get nothing at all when I start it up.
In order to flash the firmware I had to use a menu that I can no longer see, is there a way to revert it without using a menu?

Thank you so much in advance.

[dokuzovski]

can you share your backup with us ?

[ostearn]

replied below. sorry, still trying to get the hang of this forum

[ostearn]

Thank you very much, the backup zip is here:
https://drive.google.com/file/d/0B1x...ew?usp=sharing

any advice would be appreciated, even if its just to chuck it and get another.

[petesimon]

the firmware has skier welcome/goodbye logos at boot. and here is your firmware's info:

Product:   
   fuxin4k30imx179-sdv
Manufacturer:   
   fjj
FW date:   
   20160812
Version:   
   20160810V2.3
LCD model:   
   st7789v
Sensor model:   
   imx179

and is likely very similar to "Fuxin (excelvan boot logo) 2016-08-12 (shows 20160810V2.3)" on page one, in post #8. cheers.

[dokuzovski]

Obviously you made a mistake. According to your backup you have camera with imx179 sensor. So you need to look for a firmwares for that particular sensor. In order to back your camera in working condition you will need to flash a new firmware using the software called PhoenixSuit. On this video https://www.youtube.com/watch?v=fdjEcRlpYTU there is a tutorial how you can unbrick your camera. It is quite long but it will save your camera. Also if you want to test other firmwares pay attention on the lcd controller before testing. According to your backup your lcd controller is Sitronix ST7789v

[ostearn]

thanks so much! I certainly did make a mistake. Unfortunately I can no longer see the device in my device manager I love your optimism, but I fell at the first hurdle of that video really

[dokuzovski]

Did you install all required drivers like adb ?

[ostearn]

well, should I need different drivers now that it has different firmware on it? I assumed that the ADB drivers that I installed previously (allowing me to see it in the device manager) would still work. I just went through the original firmware thread and tried to install the ADB drivers shared there, but it looks like they are already installed on my machine.

[dokuzovski]

I had the same problem as you and i saved my camera with the help of the video. You will need to make .img of your firmware and next you will need to enter in recovery mode (keep holding volume up button and then connect the micro usb cable) . Next run PhoenixSuite locate the .img and flash it

[ostearn]

Dude, this worked! Thank you so much! I should just have watched the end of the video, and without you explaining recovery mode, I never would have.

[dokuzovski]

I am glad to help you

Hello forum.
I have similar issue. Camera model crane4k30imx179s-sdv, XDV logo. I flashed it with "Crane (MGCOOL boot logo) 2017-06-02 (shows Explorer Pro V1.0 / 20170612)"
Now i have black screen, i tried different ADB drivers, not recognized, Connected the camera to USB with UP key pressed and the ADB recovery driver was accepted and device USB Device(VID_1f3a_PID_efe8) appears in Device Manager.
PhoenixSuit does't see the camera. I will appreciate any help, suggestion or advise, how to unbrick the camera. I just uploaded to firmware for allwinner v3 action cameras dropbox my backup zip folder
- XDV logo Ver 20170426V3.3.zip

Before lital flashing PhoenixSuit info from the camera was like this see attachment.

[nutsey]

Could you please share full_img.fex file from your 20170426V3.3 backup to google.drive or yandex.disk?

Most likely you can recover your cam with this firmware IMG file for PhoenixSuit tool (don't be confused with adb and recovery modes/drivers): https://drive.google.com/file/d/0B4t...ew?usp=sharing

Thank you for prompt comment. Yes i uploaded full_img.fex to https://drive.google.com/file/d/0B0N...ew?usp=sharing
Trying the IMG you provided, it is accepted and now camera powers up to white screen. Should i try to make IMG from my backup and restore original state of the camera?
How to learn what lcd controller i have? Thank you again.

[petesimon]

LCD model: st9341

[niko]

I managed to restore the camera in to original state. Thanks to your forum!!
Still looking, how to learn what lcd controller i have and will try another FW. Seems to me picture on monitor with HDMI connection looks much better then saved on SD card.

Hello, i have a lazytech action cam. It is also running allwinner v3 chipset, sony179 8MP sensor. Right now i’m getting a black screen when i turn it on. I dont have any backup file or the like. I need help. Thanks in advance

[petesimon]

hello. welcome @jaysdaiz

do you here any chimes (jingle) sound when you power on the camera? do you know the firmware date or version of the camera?

please give us a full link to where you got the camera. for example: amazon, gearbest, tomtop, lazada, but full link.
please read messages in this forum thread starting at message #8, and let me know what you think...

Hi, got mine from Lazada, it is working now. The manufacturer provided a fix.

here's that camera:
https://www.lazada.com.ph/lazytech-4...y-7657696.html

If anyone can create any mod for this cam it would really help. the latest firmware update provided for this camera bricked some units here in the Philippines and their solution is to put back the old software.

good to hear your camera works again.
we don't know what exact firmware is now or was before on the camera...
so, please share copies of both firmware, the "bad" and the "good".

you can upload your files to this public shared folder

I'm a big dumb dumb and I flashed the incorrect firmware on my device Fuxin (andoer boot logo) 2017-03-02 (shows 20170213 V23): https://drive.google.com/file/d/0B4t...ew?usp=sharing

I've installed all the adb drivers and I cannot get my device to be seen by PhoenixSuite at all.
Driver installs and shows like this in device manager. See attacked image.

Here's the link for my backup https://drive.google.com/file/d/0B3s...ew?usp=sharing

You're my only hope. Thanks in advance.

[petesimon]

hello darkproteus66 and welcome. your screenshot of Device Manager is correct.
.

.
When a device is bricked then it will not show in Phoenixsuit. and there is no need for a camera device to show in Phoenixsuit anyway to proceed with recovering the camera.

Please read through all messages in this thread.
Everything you need to know to recover your camera is in that thread already. and be sure to press + hold UP button on the camera at the right time and get these Phoenixsuit drivers.

petesimon you're a beautiful person and I love you. It's all fixed now.

[petesimon]

wow! I'm flattered... yeah, I feel good because you wrote "you're my only hope" and wrote "beautiful person". but I have a crazy sense of humor too -- so I also think of the Marilyn Manson song "the beautiful people" duh duh duh. hehe

I'm glad your camera works again.

You can flash other firmware that has: IMX179s, Fuxin, and LCD st7789v, and it will should work fine.
