Hi, friend!
B593s-22 is a consumer product, and our forum is focused on enterprise devices.
Confirmed:
B593s-22 has reached EOS.
We cannot provide you with a solution, and you are advised to replace the equipment.
Of course, you can call Huawei's hotline for solutions or purchase new devices.
You can get the regional hotline number in https://consumer.huawei.com/en/support/hotline.
Thanks!
