Out of curiosity, itās been over a year since any activity or chatter on this lockā¦. Any chance theyāve changed the firmware again to allow for added tags?
Hey mate,
Iāve not touched this in a year, my ārolled backā lock has been working with my NeXT since the first publish date on the git repo and Iāve not run into the collision problem I last wrote about in practice, however Iāve also not tried to debug it either.
I doubt Samsung has made any changes to allow for more types of tags.
PIC reverse engineering is a rabbit hole I donāt have the time to chase at this point either.
TLDR:
Probably not
I just got done installing the Samsung SHS-3321 Everything is working great!
My experience:
- Creating the cable was super easy. Basic soldering, no one should be scared to do.
- Learning PCKit3: Super easy, especially didnāt have to do anything except plug and play (pay attention to the status lights, I killed some time trying to figure out if everything was working or not when I should have just trusted it was fine)
- Using MPLab IPE: super easy. Ensure you follow the screenshots Iām happy I made the back up. My firmware didnāt flash correctly the first time, and the lock would play the music on repeat. I flashed it back to the original and started from scratch and everything worked great.
- Ensure you do not have any batteries in the lock. That is the reason the first attempt didnāt work.
Other than that super easy, had great instructions, and works way better than the previous lock I had in there.

Not to be presumptuous,
But have you considered offering to rollback for others now that you know how to do it?
Could be a blessing for some on the forum
