How can I do a factory reset on my Galaxy s6 without firmware?

This is Samsung's help page for your phone .... Galaxy S6 (Verizon) | Owner Information & Support | Samsung US

As far as the usb debug that has to be done with the phone on and you have to have the developer

option on which at this point you can't do. What options do you have in Maintenance Boot Mode?

Have you tried the factory reset in maintenance boot mode?

I have tried every option available via Maintenance Boot Mode and now I can't even get the device drivers to load.  Battery works and screen works on all the maintenance features.  It acts like its going to start when Galaxy s6 logo shows up on screen, but then nothing.  No typical vibration at startup.

I was actually going to recommend what Kathy65793 recommended, if you follow their troubleshooting flow it should ultimately take you to a recovery/repair program that can be run that might be of help.

Just to confirm, you said you were using Maintenance Boot Mode and I want to make sure this is the same as the Android recovery screen as there are a couple different boot modes that can be loaded. To clarify, you have done this, correct?

Press and hold the Volume Up and Home buttons.

--------------------------------------------------------------------------------

While continuing to hold volume up and home, press and hold the Power button until the Samsung Galaxy S6 screen appears then release all buttons.

--------------------------------------------------------------------------------

From the Android system recovery screen, select wipe data/factory reset.
(volume buttons to cycle through the available options and the power button to select)

--------------------------------------------------------------------------------

Select Yes.
(Allow several seconds for the factory data reset to complete)

--------------------------------------------------------------------------------

Select reboot system now.

Have you been able to get the drivers loaded on your computer? If you can get that done and try doing  Volume down -Power -Home it should put your phone in download mode. My S5 had the same problem trying to get it started .It took a lot of times doing the volume down power home but after awhile I got it there. Once you get it into download mode the the Verizon software asst should be able to see the phone when you connect it to the computer. You may also want to try Smart Switch or Kies they could possibly help where one of the others may not

I totally understand your frustration and I am sure that is putting it politely if you are feeling like  I was then.

The main thing is that you get your phone up and running and I am sure someone on here will come up with something that will help you

Does this mean you got your phone working ? That Android Recovery screen looks awfully promising !

[DENOGA95]

Negative...Nothing...Nada!

But you do have that recovery screen right? If you use volume down to highlight wipe cache partition and hit power will that work? It should go to another screen that says no   yes volume down to say yes and hit power button if that works then should go back to same screen and then just hit the power button on the reboot system now
