How to do a Factory Reset on HTC One M7 with Lollipop

Yes, this is one of the best ways of making sure that an update is as good as it can be on your phone.  Or just sorting out various issues.

But I don’t want to lose all my phone contacts!

Done right you will not lose a single contact. I recommend that you use Google for all your contacts.

If you don’t got your phone setup that way, you can easy do it inPeople > 3 dot menu > Manage contacts > Copy contacts, where it will ask from where to copy and then to where.

I don’t want to lose my messages!

Done a guide on that before, it’s very similar in Lollipop as described in that.

And, you of course got HTC backup and other ways. I tend to keep as little as possible on my phones, just making sure that contacts etc are safe.

You’ve got two ways in doing a Factory reset.

Via settings

Open Settings > Backup & reset > Reset phone, will warn you about what it will remove. And, on the bottom part of it you have a tickbox for Erase SD card,  which you of course might want to avoid if you want to keep the content on the card.

Via hardware buttons on phone

  1. Power off phone
  2. Press and hold Vol down , press power button until you see bootloader (3 happy androids on skateboards at bottom of page). Release vol down.
  3. Select Factory reset, and just go with it.

And a third way that I almost forgot about

When wiping the cache partition, there’s an option for factory reset there as well.

    I just did the reset & carefully followed instructions & lost everything on my phone.
    I have an HTC One M7 with AT&T as carrier. I have attempted numerous times to backup to my PC using the HTC Sync Manager & was only successful in backup of my photos.
    Now my phone is more bare than when first bought.
    I didn’t think I would lose anything because that’s what the article states.
    My HTC One M7 had been running poorly for a while – battery draining, slow connections, slow everything so I was desperate, it was running so poorly.
    Please help.
    Is there any way I can restore my phone & get back my information?
    I had text messages that were extremely important. I really need these back. I also have no way to restore all of my contacts,
    I felt on my cell for too much. I had so much important information stored on it which are now gone.

    Please, if there’s any way I can restore my phone, even just parts of the information, please help me.
    I don’t know what I’m going to do. I had some extremely important texts necessary for an upcoming legal matter.
    I hope there’s some way someone can help.
