I don't know why it stops half way in windows, strange.

In some Linux you need to do

sudo screen /dev/ttyUSB0 115200

Thank you so much... Everything works fine...

Is it necessary to use ATWZ command while unbranding?

[dmcdonnell]

ATWZ is used to set the parameters listed, including Debug mode. You can change your bootloader also, if you wish, to a ZyXel built CFE. https://forum.openwrt.org/viewtopic.php?pid=246561#p246561

Thank you. After unbranding I tried to update the latest firmware from this forum via normal way but it is not allowing to do that. Do I have to flash new firmware from CFE? Why it is not allowing even after flashing zyxel firmware once.

[dmcdonnell]

Did you set cfe debug mode? Did you flash the ZyXel bootloader? Which firmware are you trying to flash?

Thanks for your time and help...

Steps that I did
CFE> ATSH
CFE> ATSE DSL-2492GNU-B1B
Then navigate to http://www.tonycool.es/zyxel/zynpass_en.htm site and generate the password

CFE> ATEN 1, password
CFE> ATBT 1
CFE> ATUR

From Another terminal trafered the V100AAKL0C0.bin file xModem

This is the firmware that I tried in normal way after the above steps.

If you did not set Debug mode, as per the instructions, you have not unlocked the bootloader.

Thank you I'm confused about that step. In that step you provided mac address along with some other values, where can I get all those values. Sorry about noob questions.

Feature bits are unknown for this model. I see no public data. However, we're not changing any. Simply follow the command in the instructions, with your Mac address rather than the one in the example. I recommend flashing the ZyXel bootloader, ATUB does that over xmodem. It will enable you to flash future ZyXel firmwares from GUI.

The number of MAC addresses is 12, decimal, 0c in hex. 01 sets the debug bit and you can use whatever country code you wish.

Interrupt the boot and upload the ZyXel firmware. Try to do this by entering ip address 192.168.1.1 in your PC browser. You may have to set your PC ip address to 192.168.1.100 to achieve this. If it does not work for you, use the
