It appears sd2812 ticket was "assigned" does this make it any more likely this router will see DD-WRT support?
Hope dd-wrt started work and love to see dd-wrt support for this model.
R8000P has encrypted CFE and it is difficult to make port for this model. Only a Merlin ported firmware support for this router, topic discussed on right.com.cn. But the firmware is cfe rom and in squbi.w format (Asus-wrt use this) instead of .bin or .trx and flashing guide not disclosed. May be this Merlin ported for business only and available for China only.
I haven't seen any development in the public repo, and I have not followed up with the developer. If it's going to happen, a new router needs to be donated for the cause, if it hasn't happened already since the one in hand got damaged. At present, it seems RMerlin is the only one to have a custom firmware ported.
