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...

see part 2 'Flash firmware via serial cable (U-Boot)'
also you will need such tool
then download the firmware forceware 1.4b1 mod1
then read this http://www.haxorware.com/forums/showthread.php?tid=3025
also will be necessary to disable 4 downstream channels in the settings of forceware, because otherwise this version will work unstably (see tutorial)
Serial cable connector
upd: at the time when the modem is loading, it is necessary to short the eighth chip contact on the modem case as soon as the message appears
'Hit any key to stop autoboot: 0'
after this the loading will be interrupted
type
> printenv
then type
> setenv forceboot 0
> setenv bootdelay 5
> saveenv
then after rebooting the modem when the line appears
'Hit any key to stop autoboot: 5'
press SPACE bar
then see the part 2 'Flash firmware via serial cable (U-Boot)' in the manual https://ru.scribd.com/doc/62539505/SB621...emod-Guide#

no, a noob yes but middle no, this is basic modem hacking
it's hardly a full hard mod as theres no need to solder anything and all the tools needed to hack this are under $10
