DPC2100R2 HELP !!!!!!!!

[mmr_22]

I know this is an old post but just wanted to know if I could get some help in regards to this same topic:

I'm trying to install the firmware through ethernet cable on a DPC2100R2 modem with v2.0.2r1256-121012. After I launch the DPC2100R2.bat file it says the following:

C:\>snmpset -v2c -c public 192.168.100.1 1.3.6.1.4.1.4413.2.99.1.1.1.2.1.2.1 s p
assword
Error in packet.
Reason: notWritable (That object does not support modification)
Failed object: SNMPv2-SMI::enterprises.4413.2.99.1.1.1.2.1.2.1

Press any key to continue . . .

C:\>snmpget -v2c -c public 192.168.100.1 1.3.6.1.2.1.1.1.0
SNMPv2-MIB:ysDescr.0 = STRING: Cisco DPC2100R2 DOCSIS 2.0 Cable Modem <<HW_REV
: 2.1; VENDOR: Cisco; BOOTR: 2.1.6d; SW_REV: dpc2100R2-v2.0.2r1256-121012as; MOD
EL: DPC2100R2>>
Press any key to continue . . .


Why it says it is noWritable and that the object doesn't support modifications.

Do I need to install something in the modem before this.

Thanks for you prompt help.
