Bricked Device?

[tobs1895]

Hello, I followed this nice tutorial. I came till step 11 without problems, but when I tried to write the flash with new the file (fullmod.bin), I recognized it was too big. It could not be flashed. I think I missed something in the modifying process. Due to, I already had done the erasing command, I decided to flash the original fulldump.bin file. Then I did the reset.

Now I only get these two lines output on power on:

ROM: Use nor flash. ERR: Flash is corrupted

Is that a U-Boot message or is U-Boot lost? Do you know where U-Boot is stored?

Thanks a lot!

Hi Tobs thanks for reaching out.

I am not sure what happened that would result in this state. It should definitely not be bigger than the flash. That would result in a corrupt flash indeed.

I have followed my own instructions in this repo with multiple camera's and never had issues.

Maybe somewhere the tutorial you have missed something or maybe you have an older/newer model. The most important thing is that the camera has a Fullhan FH8626V100 Soc. You will find this specific model on the camera.

If you can give me the fulldump.bin and the fullmod.bin file I could check out what went wrong.

I see you have bricked your device. No worries. I made the same mistake before. You can still re-flash it using a ch341a programmer. https://www.amazon.com/KOOBOOK-CH341A-Programmer-Adapter-Converter/dp/B07VMPZFWH

If you still have issues I can modify your fulldump.bin and send it to you, or just give you my own modified dump.

Cheers!

Hello Berobloom, thank you for your help. with the CH341A Programmer I could read the Data of another Camera and unbrick the first one . It worked well! Maybe its related to a bad SDcard. I tried a few things like formatting and writing zeros to SDcard, but the file I get with this card is completely diffrent to that I grabbed with the programmer. Sadly I do not have anther SDcard to have a try at the moment.

Have a nice day and thank you very much for that nice guide!

You are welcome. Contact me if you need any help.

Hello Berobloom, I need some help again. It seems to me the cam is running, but I can not connect. I tried with tinyCam and with the LSC-Prox. no luck. Maybe it is a problem with the credentials. I tried with default PSW and also generated new credentials with the same result.

Here is the console-output of dgoit. Maybe it helps.

Hello @tobs1895 ,

I miss some output of the init script that is run before the execution of ./dgiot. Are you sure you followed everything in the instructions?

[berobloom]

It has been a month. I cannot reproduce this. Let me know if you need further help. I will close this issue.
