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

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

How old is your phone? Were You having battery problems with it before this?

Are you able to do Volume down-power-home This will put the phone in download mode

if you have a computer go here and get this and plug your phone into the computer it will see what the problem is. If it is software it will put the latest software on it. If it is the battery or something else like hardware then that will be another avenue you will have to get checked out

I just reread your post try doing the Volume up-power-home this will put the phone in recovery mode

and use the volume down to highlight the clear cache partition press power then volume down to say yes

hit power again then volume down to factory reset and power that will do the factory reset and the clear cache partition will clean out any old files that are in the phone

Hope this helps

You realy don't have a clue how to fix this phone. I suspected as much.

I apologize if this has not helped with your current phone problem. Does the phone not do anything.

When you do try the volume up -power-home nothing happens? I do agree about not being able to take the battery out is such a dumb thing to do. They would not had to recall the Note 7 if they had just let us replace the battery .I know of one site that maybe able to help you

Again this is just a suggestion

Someone is trying to help you. Why are you being rude to them??

OK....I'm slightly frustrated with my s6 and taking it out on "Support Team" is not cool. My bad...can you help me at least load drivers. Every time I connect phone to PC it tries to install drivers and I get the following response.

I know the feeling, however the person trying to help you isn't the "Support Team". They are a community member like you, and myself and are just trying to help you out.

In any case, with the drivers-- do you know if you have USB debugging enabled by chance?

I’m not sure. How do I enable debugging?

Try this first, and then connect to computer to see if driver's update after completing...

Taken from: USB Debugging Mode - Samsung Galaxy S 6 / S 6 edge | Verizon Wireless
From a Home screen, navigate: Apps > Settings > Developer options (System section).
If not available, navigate: Apps > Settings > About phone then tap Build number seven times.
These instructions apply to Standard mode only.
Ensure that the Developer options switch (located in the upper-right) is turned on .
From the Debugging section, tap USB debugging to turn on or off.
If prompted, review the message then tap OK to confirm.

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 !

Negative...Nothing...Nada!
