objcopy is your entry point to modifying a binary.
or
just generating a modified one from the sources.

Most likely, combine the two methods (the original binary + just the binary modifications):

Reading the ARM instructions that you just dump'd will answer your questions about
"Where / How do I change the limit on the array length?"
"What is the storage format for mime types?"
and just about any other question you might have about how it works / how to change it.

Sometimes changing the behavior of a binary does include the WAFG (Wild Ass F...ing Guess) protocol you mentioned - but only rarely.

Give up on the built-in browser - just install one of our alternate browser packages.
(If we have a build for the K3 that is, I don't recall off-hand if we do.)
