How to resolve the quarrel with my brother by texting?

First of all, I think the content in the text message must be full of apologies and take the initiative to admit mistakes. If it still doesn't work, I suggest the landlord buy something he likes and apologize in front of him. The most important thing is to admit his mistake voluntarily, even if his mistake is bigger than yours. If he puts all the responsibility on you, you want to keep this relationship bearable, but if you really can't bear it, you can vent it elsewhere. Don't wronged yourself.
