To do those kinds of tasks on the Omni 3750, you need to put the terminal into "system mode". Since once in "system mode", you can not only erase the previous applications, but you can also erase the operating system, I do not want to post that information on the web for everyone to see. I would recommend that you contact a terminal repair shop and ask them to walk you through that process.
Do you have the capability to reload the operating system?

I bought a used Verifone omni 3750 and it says download needed but it won't take any password we have tried. Is the machine just a gonner?


This unit is repairable. Change the battery and do the download needed to bring it back to factory reset. This will set you up for application download. Call Frank 775-338-6634

Need to reset a VeriFone 3750 v501 to its original default state. The program password has been changed and I cannot access to update


Turn off and unplug the Verifone 3750. Wait for five seconds or so and then plug it back in. This will automatically reset the Verifone 3750 and it will reboot and restart.

Reset the shift. Resetting the shift is another reset option available for Omni. Press "Shift," then "#," followed by "1" to reset and change the shift.

Press "Shift," then "#," then "2" to stop a change and keep the shift on the current settings.
Below is your user/install manuals, it's all in there so download each copy for any time later.

I have a verifone 3750 terminal when stated message on thescreen is " download needed no *go variable" 1alpha alpha 66831 do not work


Press the F2 and F4 keys at the same time and it will then prompt you for a password. Enter 1alpha alpha 66831.

This takes you to the programming screens where your processor enters in their platform settings to perform the software download for your account. Without a valid download from your processor, the terminal will remain a blank slate.

Hope that helps
