did you use autorcm since V6.1? Because that prevents the fuses getting burned. if not, youre not able to downgrade... if you do it anyway, you end up in a softbrick like that.
Possible workarounds::
1 - Enable AutoRCM - AFAIK it should boot up when installed
2 - Restore NAND-Backup with V 8.1 if you have one
3 - I think there is a possibility to build your own NAND backup... but its not easy and i dont know how to do it

If i´m wrong.... correct me

This has to do with fuse count, until you update you need to use hekate or fusee primary or any other payload that bypasses the fuse counting.

———————————————————

8.1.0 burns 10 fuses, 6.1.0 requires 7 fuses. Update your system using choi.

Which payload are you using? What does your injecting program say? Are you sure you are in RCM?
