Problem with YI Dome Guard YRS.3019 with v12 firmware

[akkasss]

Dear friends,

Can someone help solve such a problem?
Some time after updating the firmware to the 12th, the camera entered a mode in which it cannot connect to the router.

I tried to reset the camera, it doesn't help.
The camera successfully scans the QR code, reports "Connecting to WIFI", but then again "Reading to connect".
I read in internet that many people have such a problem after updating camera firmware to 12th.

On SD card I found ps1.txt file (in the "no_wifi_dev" folder).
Also, there are other files on the SD, including log-files.

I tried to make a firmware backup, but no new files appeared on the SD.
After that, I tried to install the r35gb firmware, but apparently it does not install, because the camera behaves the same way.

Thank you so much for your help!

You should try the unbrick procedure.

However, when the camera is turned on, it turns and speaks. And i have no backups.

I will check if I have a backup of the old version.
Are you sure your cam is s r35gb?

The inscriptions on my camera look this:

As far as I understand, is r35gb suitable for my camera?

Is there a way to restore the old firmware version from the manufacturer, for example, the 9th?

The label is not enough to know exactly the model.
You need the whole fw version 12.x.x.x or 9.x.x.x

Maybe I can use this firmware? https://kamihome.com/firmware/

How can I check the fw version if your camera refuses to connect to the router due to the fw update?

[roleoroleo]

Do you have a backup of the original fw?
I could open it and check the version.

[akkasss]

Unfortunately, I don't have a backup, because the camera stopped connecting to wi-fi unexpectedly
However, here is some kind of firmware for YI Dome Guard: https://kamihome.com/firmware/

Please try to install r30gb hack.
If it doesn't work, I will try to send a backup firmware.

This site contains only partial firmware and you can't use them for the unbrick procedure.

I seem to flash the camera (r35gb 0.2.9), since the 'Factory.done' folder appeared on the sdcard.

However, if I don't use 'configure_wi fi.cfg', then I still can't connect it to the router via YI Home using the QR code.

If I use configure_wifi.cfg, the LED starts flashing green and the camera does not talk. However, I do not find my camera in the list of devices connected to the router and I cannot connect to it with a browser, since I do not know its IP.

[akkasss]

Does YI Dome Guard YRS.3019 need to use r30gb, not r35gb firmware?

[akkasss]

Here is a backup made by your firmware: https://dropmefiles.com/iDBPN

Sorry but I didn't have time to download the file, can you upload it again?

Yes, it's a r30gb.
Partitions are ok. So I think that a firmware restore (with v 12) won't fix your problem.
You should try to restore fw 9.

Or...
Did you try to use the new hack procedure where you can set wifi credentials?
It's not released but it's commited and I could send you a beta.

Hi,

I installed FW 12.1.05.1 und YI-hack 0.3.2 r30gb

PTZ and rtsp-stream didn't work.

Can you help?
