OpenWrt for Sercomm Model S3

This device doesn't support 22.03.3. Only snapshot.
Check your MAC address in Network Interface. If it changes on everyboot you probably lost your device configuration & wireless firmware in mtd2 partition. confirm this then i will send you dump of that partition for restoration.
For usb to work boot flag should be 0
"Boot Flag : Sercomm0"

I have checked mac addresses, it remains same on everyboot.
how to change boot flag to sercomm0

You can share dump file with me, I will give a try and will let you know, also tell me how to write it with ssh.

The image you had installed doesn't contain wireless drivers for this router. Update snapshot image & install luci. Wireless will be ok.
For bootflag follow This Guide
I have uploaded mtd backups of this router here OEM_MTD_Backups
