No more WiFi connection Dome camera 1080p (log_no_wifi_dev)

[Veritas999]

Hello.
I have 2 Dome 1080p cameras.
After applying the settings in the web interface, one camera lost Wi-Fi connection.
The camera can be flashed in stock and yi-hacks v4 and v5. But it cannot connect to wifi.
When I turn it on, I hear "Waiting to connect". Then I select the network, the qr code is generated, the camera reads it without problems: "QR code scan, connectet to WI-FI", the blue diode blinks, then lights up yellow and reboots. And so endlessly.
The loops are ok. I tried to swap boards, the problem is the same on this board with different cameras.
The login and password are correct in wpa_supplicant.conf.
What do these lines mean in log.txt?

What is the Hardware ID? The first four digits are at the back of your cameras.

Any solution? Maybe there is a special firmware with a rollback to the factory?

[alienatedsec]

Have you tried manual wifi connectivity?

Also, when you flash the latest firmware (hack or whatever) please ensure you have a FAT32 filesystem.

What does it mean

#193 and 98f3db1

Let me know how it went

[Veritas999]

I correctly understood, creat configure_wifi.cfg file at the root of the SD card, and write two lines with my data?
wifi_ssid=[your_wifi_essid]
wifi_psk=[your_wifi_password]

Does not help. It tries to connect again, reads the qr code, reboots and starts all over again.

you will need to place the configure_wifi.cfg file in the /tmp/sd/recover/ folder and restart the camera

Those two lines should be in the file, yes:

wifi_ssid=[your_wifi_essid]
wifi_psk=[your_wifi_password]

Replace [your_wifi_essid] and [your_wifi_password] with details matching your WiFi network. DO NOT configure anything using the QR code.

No sir. All the same when power is applied "Waiting to connect". Perhaps the mechanical damage just happened. Thank you!

Perhaps the mechanical damage just happened.

no chance

Try recovery firmware, e.g., one available here:

[Veritas999]

Yes, I tried. And not only this one. With any firmware, the camera can be flashed. Those the yellow diode is on for about a minute, then it blinks and reboots. But after always "Waiting to connect".

[alienatedsec]

Try this file

home_h20m.zip

extract and place in the root of the SD card (it has to be FAT32)

[Veritas999]

Same. Flashes, reboots. And then a cyclic connection.
Thanks again for your help!

[alienatedsec]

Please don't give up on this.

It would be worth comparing if any files are missing or even deleting some and reflashing.

I'm ready. But there is no access to the camera, and I am good friends with a soldering iron and screwdrivers, but not in programming.
