arris cm820 docsis 3,0 how to hack

[andytg]

from sbhacker:

Hello everyone,

If any of you have a Arris modem such as the 820A, 860A, 852, 862G, etc and happen to have a locked bootloader. Do the following:

- Dump the flash with whatever you can use to dump a SPI flash.
- Load the backup into a hex editor.
- Search for "forceboot=1" (there will be a few instances of it throughout the flash)
- Modify "forceboot=1" to "forceboot=0"
- Save it.
- Reflash back.


Yes, change all instances of bootdelay=0 to bootdelay=5 on the Compal modem.


Shorted pin 8 to get into bootloader - thanks parker...
