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

hello,
anyone help me to install this firmware step by step
i have hard bricked my sercomm s3 ac 2100 router
i was flashing the openwrt firmware but sudden a network issue leads to bricked router
i had tried unpluging and repluging,TFTP, linux, while in putty it is not taking any password
what i can try
I follow all instructions from this link https://openwrt.org/inbox/toh/sercomm/s3
after that i cant access to the 192.168.1.1 (refused to connect error on chrome)
on PuTTy i can login via root user
please guide what should i do next to complete the installation
Thanks
I assume you installed a snapshot version, which doesn't contain LuCI (the web interface).
Do you have a running internet connection on your sercomm router?
If so, after you login using PuTTy just enter the following commands:
opkg update
opkg install luci
That should do the job.
