why cant i downgrade my router ?

from all reports, till date stable version is 6.32.4 and 6.30.4

i got a ccr1009 and it came with 6.34.2

i need to downgrade it to 6.30.4

but it shows error saying omitting package.

what to do ?

i need to downgrade immediately, as the router has peculiar issue.

the bandwdith even if if used for 3Mbps, the ping breaks to upstream and latency goes to sky high.

what to do now ?

There is such documented feature.

You should search and read before you ask…

The router might hang or work badly with older ros version because of possible hardware changes that were not supported previously. Rather update to newer version.

updated to latest 6.37.1
same issue.

bandwidth usage is dropping packets even at 2Mbps and latency goes sky high.

Then you have some misconfiguration for sure, if the problem is inside the router. Have you updated the firmware too after the ros update?

are you doing any layer7 firewall rules?

No sir, nothing!

No mis config. everything looks fine.

what shall I check ?

and router is lays 6.37.1

What is your firmware version?
