Upgrade cisco 2811C to IOS

IOS features of Cisco devices
2811C has spservices and advipservices IOS. The features of advipservices include pptp with mppe, but spservices do not. Unfortunately, I bought spservices (show version shows the information .)
Then I found many 2800nm-XXX IOS, but they couldn't be started. I recovered from ROM mode many times.
By the way, write the method for restoring IOS from ROM mode.
IP_ADDRESS = 192.168.1.2
IP_SUBNET_MASK = 255.255.255.0
DEFAULT_GATEWAY = 192.168.1.254
TFTP_SERVER = 192.168.1.1
TFTF_FILE = (IOS file name)
Tftpdnld
This command is case sensitive.
I found a lot of information on the Internet and said it was a problem with licensce. It was very depressing. I don't know what channels I can use to get this.
Later by chance I found that the IOS name from the machine dump is c2800nmc-spservicesk9-mz.150-1.M5.bin, but the IOS name is c2800nm-XXX. What is different? One is c2800nmc and the other is c2800nm. These two are incompatible! Start looking for crazy looking for c2800nmc-XXX IOS, after the Wall to find a file c2800nmc-advipservicesk9-mz.151-3.T.bin, began to use tftp irrigation in, waiting for more than half an hour, the miracle of the boot successful
Ppp enc mppe can be executed.

Finally, how can we see that the support does not support this IOS? In fact, I ignored something during IOS injection.

In fact, this IOS cannot run on this platform. What if it can be used?
