Hello guys, this might be another noob question so please dont flame. I’ve been searchin this site but havent come up with the info I needed. I recently flashed my 3500 to the quickee v2.28, but now I wanna bring it back to the original version I bought it at which was v2.18. How would I do so?

The same way you flashed the modded firmware… just now you have to use 2.18 original firmware instead :wink:

thanks for the quick reply quikee, but when I downloaded firmware from nec’s website and I clicked on the flash it said “target NEC ND-3500A is not found correctly”. Can you enlighten me…

Well… you can select in BinFlash the downloaded Nec flasher instead of a .bin file. It also works this way.

xxpnoisnxx! I did the same thing and binflash works everytime. I added an extra step and removed the old FW first in binflash then you can dump anything into the drive(donuts, coffee, etc).
