any help?

as can see, partitions in dumchar_info type 2 (=emmc, not mtd), use cat /proc/emmc instead of cat /proc/mtd".

anyway might use mtkdroidtools rua1 create scatter file mtk device, load scatter sp flash tool, click on read tab, add desired address , size of recovery partition dump file.

to find address , size, open scatter file in text editor, copy hex number after label revocery (this physical address in emmc), subtract next partition's address (this size).

or can use sizes dumchar_info, don't use addresses, because addresses relative addresses related mapped devices.
