Help how to factory reset (not the 2 obvious ways)

Hi all,

Apologies if this has been asked before, but I am trying to factory reset my phone before I send it back to the phone company. I have tried the 2 methods that I know of (through the settings and hard reset), but they don't work. If I go through settings, I go through all the steps but when I tap on the final ok to reset the phone nothing happens. Well, sometimes. Sometimes I get the rebooting message and sometimes it does actually reboot, but the phone is as before. Hard reset is even more interesting. I go through all the steps, I get the 'reset done' or whatever it says at the end of the procedure, but the phone is as it was.
This may or may not be part of the same problem, but I have similar issues with removing accounts (Google, Exchange email, etc.) manually. I remove them but then, when I restart the phone, they are all back. Same thing with apps. I just spent 15 min removing apps one by one manually, but they are all back! It appears that my phone has picked a 'state' to exist in, with certain apps and settings, and won't deviate from that no matter what I do.
So, back to my original question, is there a way to reset the phone apart from the two obvious ones? I would really like to be able to send the phone back clean, instead with loads and loads of private data (like bank accounts, google details, etc.) hidden somewhere in the phone's memory.

Many thanks,
Dimitris
 
Hi Dimitris

Do you have a Google account set up on the phone? If so you may be able to use the Android Device Manager to zap your phone. You can access it from the Google Play Store apps page in a browser by clicking on the "Gear" (top right of page) and selecting "Android Device Manager" from the pop-up menu.
 
Best way to do it to stop people from recovering your data:

Remove SD Card if one is inserted

Goto Settings>Storage then tick "Phone Storage Encryption"

Wait for your phone to finish

Switch off your phone

Switch your phone back on while holding down the Volume Down button

You should have a white screen with 3 skateboarding android robots at the bottom

Use the volume down button to highlight "Factory Reset" then press the Power button.

Thanks for your replies.

John - tried that, without success. I'll give it another shot anyway.

Fonzig - good idea about the encryption. The only problem I foresee is that, when the phone gets even a little bit 'stressed' (i.e. do something that requires a bit too much thinking), it resets. I'm worried that it will do that during the encryption process. I've tried the factory reset the way you suggest, but it didn't work (even though it says that 'wipe is complete' at the end.

If none of those work then how about trying it via adb/fastboot:

If you don't have fastboot and adb setup then Google it and then plug your phone in via a USB cable to your computer and do the following commands:

adb reboot bootloader

fastboot -w

Or try this route.
 
Unfortunately, adb commands didn't work, as the device 'could not be found' (even though the drivers were installed properly). Oh well. I've sent the phone back anyway and changed all my passwords. It's so messed up that I'd be surprised if anybody could get anything out of it anyway. Thanks to everyone for their suggestions, much appreciated.

Cheers,
Dimitris
