Simplex Buggy After Downgrade To 2.77 (FIXED)


Recommended Posts

Finally got it back. It got delivered to the wrong house. The connection is tight now and no more coil errors. Left it turned on in the tub last night just to be sure. I will try to email the tech and ask what he actually did to fix it. Now maybe I can finally give 2.77 vs 2.78 a try again.

Were you able to get 2.77 to work? Also hoping you can share this file with me because I can’t find it anywhere:(

I had no problems changing to the v2.77 .. I have wired waterproof headset .. maybe that makes a difference, but I don't know .. IMO the v2.77 is the better of the two .. at least it makes the machine run like I believe it should, getting the most from under the coil .. I was really unimpressed when I bought the simplex with the v2.78, there seemed to be a 'wall' (I don't know how else to describe it) which wouldn't allow the machine to detect anything deeper, or at least report anything deeper .. and I was thinking of selling it, until I made the switch .. now I kind of like it for what I use it for.

Do you still have the 277 bin file?

I got The Simplex in November 2019 so it had 2.68 on it...I upgraded to 2.76 then 2.77 in April 2020..Then up graded to 2.78 in December 2020...After all those versions i felt like the original 2.68 was the best..I successfully downgraded to 2.68 in Jan 2021 and the detector is fine..Good luck with yours..

Can you please share version 2.68?

If you've got 2.78 on the detector it seems they say you can now no longer roll back to 2.77 or any previous version.   I don't know why, back when I was fiddling with my Simpex I was bouncing between versions testing results in different firmware and it flashed back fine. 

From their website:

IMPORTANT!

SIMPLEX+ CANNOT BE ROLLED BACK TO 2.77 OR ANY PREVIOUS FIRMWARE VERSIONS.

Software Update (2020.06.02) : System Software V2.78
