Have you checked the list at https://3ds.hacks.guide/ntrboot to see if your DSTT has a compatable flash chip to use ntrboot properly

According to that, not all DSTT carts are supported. Yours might just be one of the unsupported ones.
Edit: Try the DsttFlashChecker from here: https://www.linfoxdomain.com/nintendo/ds/?mode=desc&fileid=2112
Compare with the list from here: https://gist.github.com/Hikari-chin/6b48f1bb8dd15136403c15c39fafdb42
According to the comments on that page, using an older version of the flasher might also work, even if the chip isn't listed as compatible.
