First post. Please be gentle.
I'm a long time DD-WRT user. So far all of my routers have been Broadcom based. WRT54G, e1200, e4200, r8000. Previously I had stuck strictly to kongac builds for one reason. They worked. Don't ask me why but I recently tried some of the newer BS (that's brainslayer) builds and quite frankly, I'm not happy with ANYTHING starting with the number 4! It appears their access to BCM proprietary drivers has ended. They've introduced an experimental driver variety that apparently is using a newer open source driver but that too has it's share of problems. And so I have again reverted back to using older kongac builds exclusively. That's no BS!
After doing a bit of reading here, do I understand correctly that OpenWRT builds as of 19.07.x now work correctly on BCM based devices like my r8000? Potentially my others too? If so, I am ready to defect. I am SO ready!
What I need to know is, must I revert back to stock firmware first or can I flash directly from the DD-WRT web interface to the OpenWRT .chk file? The only reason I ask is because every example I have seen so far that requires reverting back to stock only involve Atheros devices.
Thanks in advance.
