(bmips: rename BCM63168 to BCM63268 BCM63168 and BCM63268 are very similar and Broadcom refers to them as BCM63268 in GPL sources (e.g. 63268_map_part.h). Use alphabetical order for supported bmips quirks. Add BCM63268 to devicetree documentation.)

Firmware: Under zyxel-p8702n-bcm63xx/firmware/p8702/ are all the official Telenor Firmwares I have, the latest are missing, the latest known working not to be locked to Telenor WAN is 100AAJX14D0.bin , to flash this, older, or different firmwares the router needs to be put in a special mode, i'll get the techincal details later, but it involves holding the 'reset' button untill a light blinks red, set a static ip via ethernet cable to i believe 192.160.1.x and connect to 192.168.1.1. This should be in the linked documentation above.

To force flash firmware: from zyxel-p8702n-bcm63xx/doc/bcm963xx_bootloader_appnote.pdf : "

  1. Press and hold the reset button until the “DSL” LED goes on. It will take about 8 seconds.
  2. Configure a PC Ethernet connection with a static IP address on subnet 192.168.1.x.
  3. Open a Web browser to IP address 192.168.1.1. The following screen will appear. " To flash a non Telenor WAN locked firmwre, you can now select: 'zyxel-p8702n-bcm63xx/firmware/p8702/100AAJX14D0.bin'

A bit of copy-paste from zyxel-p8702n-bcm63xx/doc/oldwiki.archive.openwrt.org/toh/zyxel/zyxel_p8702n.html:
