Hi @roleoroleo thanks for your great job. I have a camera y211ga with the same 12.0.37.0_202211241030 firmware. The camera was updated using original Y! app. And now after a reset I can't connect anymore to any wifi. Always getting Wifi connection error. Then I try with the hacks y211ga_0.3.1.tgz and y211ga_0.3.2.tgz and the backup is done automatically but nothing more. Setting up the wifi with configure_wifi.cfg doesn't work and using QR code still getting the same error. I don't know how to downgrade or fix this error. When I apply the hack, the camera boot at first time, create the backup and reboot normally. The hack never create the LOG folder.

I can downgrade to 9.0.36 but I still have the wifi error. Even after apply the hack. But now I get a log. Here are some: log_pwd_wrong.tar.gz log_pwd_wrong2.tar.gz

Try again to pair the cam with the original Yi app. Don't use a 5 GHz wifi, bring the cam near your access point and try again. If your AP uses wpa3, try to disable it.

Tried with: -Reset several times -8 different power supply (3 original Y! and 1 new) -Different USB cables (original new too) -5 different routers, wifi, SSID -Last wifi try, old 54G router with WPA2, WPA and TKIP, AES combination. -Y! app with QR code hacked or restoring -Hacked with WiFi settings (permanent blinking Blue led after booting)

The problem start with firmware 12.0.37.0_202211241030. I have 5 cameras with this problem. In this test, I downgraded to 9.0.36.00_202011101611 using only mtdblock2.bin 3 and 4 from y211ga_9.0.36.tar.gz for creating rootfs_y211ga, home_y211ga and backup_y211ga.

Where are stored the wifi drivers? The downgrade restore old wifi drivers? If the wifi drivers are stored in other partition than 2,3 or 4, I think that maybe the drivers in firmware 12.0.37.0_202211241030 are broken.

mtdblock3 and 4.

The downgrade restore old wifi drivers?

Yes.

If the wifi drivers are stored in other partition than 2,3 or 4, I think that maybe the drivers in firmware 12.0.37.0_202211241030 are broken.

Maybe.

Thanks for you answer. I am currently blocked, I don't know what to do anymore. I went back to version 12.0.37 and everything is the same. If I think wrong, it seems to me that the Kami people made some update that blocks devices for those of us who do not pay the monthly service.

Maybe a hardware failure.
