[Question] Problem with Recovery

I have two problems:

1. I tried to flash it with the SPFlashTool and with the scatter & recovery files. But the problem is that it loads the old stock recovery. While I got the green check that download is ok.

2. I tried to do this with ADB, but it seems like that this does not work either, I'm getting the error:
C:\Users\Laurens\Downloads\>fastboot flash recovery recovery.img
target reported max download size of 134217728 bytes
sending 'recovery' (9214 KB)...
OKAY [ 0.315s]
writing 'recovery'...
FAILED (remote: download for partition 'recovery' is not allowed
)
finished. total time: 0.332s


Does anyone have a idea how to solve this problem. I also tried the oem command to no avail.
