Hi. The files for the Note10+ are finally available for download and flashing. The procedure is the same as for the S10 and may be consulted here.
It's untested at the moment if the files work for the regular Note10 too. Purely technically speaking, it should. Maybe it will work perfectly, except for the camera. Indeed, one of the true changes between the two devices is the presence of a Time of Flight (ToF) sensor for the camera. If the software expects input from it, the camera might not work properly or at all. Again, this is untested as I do not possess a Note10.
The version for the Note10+ is ZSK3.
