So I "found" an easy method for uncapping and it works in my ISP but I cannot speak for others. What I basically do is disable SNMP on modems using SnmpCfgAdmin or NET-SNMP, keep in mind these modems are Subscribed to an internet plan with no modded firmware or anything, anyway once SNMP is disabled I call up the ISP or go on their live chat and have the internet speeds upgraded for that modem. Then because SNMP is disabled when they Update the speeds for the modem it does not reboot. They do not tend to notice this they just say "It should update within a few minutes" (Gotta love "dumb" phone reps) anyway I then reboot the modem manually and it picks up the higher speed config and then I call back into the ISP and downgrade the internet plan again. Because the modem has SNMP disabled it does not get rebooted to pick up the new config and just continues running on the higher speed config and you will be billed for the lower speed internet plan. I have tested this with 4 different DOCSIS3.0 Modems on my ISP and it works they are all running on a 400down config now (Too bad they are not mine) lol anyway ya you can even cancel your internet plan if you want too and the modem continues running just fine (On My ISP anyway) ....feel free to to try it I guess, but remember if the modem gets rebooted due to power loss or something else your gonna have to do this again to re-gain higher speeds. I do not recommend doing this too much as they may notice something is up.
Edit: suppose i should have told you all the OID to disable SNMP set 1.3.6.1.4.1.1166.1.19.3.1.14.0 to a value of 0
