Indeed, if you don't work under Windows, you need another access like that of Tony to calculate the password, best suitable for web broser.

I used the ZynPass.exe, but you can use any password generator like that from Antonio (Tony).

Maybe this step could be avoided, but also defines an 'end point' for this procedure, because it's not necessary to load customized MAC and serial numbers too. Yes router reboots but I prefer to force manually rebooting after flashing process to ensure all memories and parameters are actually restarted in the router. Cornelus2009 found DSL-2492HNU-元v2 as x parameter for his P-2812HNU-F3 (from Telenor). It could be 'smile' or 'wierd' or any strange word, not related to model. Yes, it works in most routers, it's just a 'word' I had when I look to GPL sources and found this 'jocking' parameter just needed to avoid us to use ATSE command, so it has no meaning more than being 'secret'.

This command changes MAC address in working buffer to the right one in the router label/stick Where MACAddress is the First MAC address obtained in step 9

This command changes serial number in working buffer to the right one in the router label/stick Where SerialNumber is the Serial number obtained in step 9 This command copies manfacturer data from flash rom to working buffer (RAM)

Observe Debug Falg is enable in the new boobase, by default. Repeat steps 7 and 13 to get access to ZyU console Now it's necessary to customize the serial number and the MAC address to match label in the router. Restart the router (switch off and then switch on) This command uploads firmware file from TFTP Base directory folder to the router, erases the flash and writes new firmware This command uploads bootbase file from TFTPD Base directory folder to the router, erases the block0 flash and writes new bootbase This command unlocks block0 in flash memory where bootloader resides. This command activates Enable Debug Falg. Where password is the password we previously obtained in step 11. Introduce previous seed number provided by ATSE command in seedNumber field, then push Generar button and obtain the password for ATEN command in Password field

Where P-2812HNUL-F1 is the x argument of ATSE command. Take note of Serial number and First MAC address values X)Ĭopy bootbase file 304TUJ.bm and frimware file 311TUJ0C0.bin to TFTP Base Directory folder (where send/receive files are stored) ) will be executed in Tera Term Pro, that is in ZyU console.Ĭonfigure to bind TFTP server to PC LAN port (192.168.1.

Unmount front panel of ZyXEL P-2812HNU-F1 using screwdriverĬonnect FTDI TTL cable (just GND, TX and RX cables are needed) to the router board as indicated in the following image Now working with this router and firmware version 3.11(TUJ.0)C0 I previously downloaded from ZyXEL FTP server. I finally got it: I unbranded or changed the firmware from my ZyXEL P-2812HNU-F1 router.
