How to Reset LG G5 G4 G3 Screen Passcode without Losing Data

Do not forget to backup your phone’s data before doing a factory data reset. Here’s our guide.

Performing a Factory data reset restores your device to the original factory settings as it comes out of the box.

Now here is how you can hard reset your LG G2/G3 from device Settings:

Tap the Menu key from Homescreen.
Select System settings> General.
Now scroll to PERSONAL.
Select Backup & reset option.

Formatting a phone doesn't make it do anything for it. There's actually no such thing as "formatting" a phone.

You can delete programs, texts, call logs, pics, and other stuff that might be slowing it down. That usually helps.

Or you can do a factory reset, lose all your media and start from scratch, as it was, out of the box.

But I'm sorry. There is no formatting a phone to make it work better. Their phones, not computers

Have you started up in a different mode yet? Safe mode, etc? https://support.apple.com/en-us/HT201573

check ram
try hitting f8 on boot see if you can get into safe mode?
if u can then try running chkdsk /f in dos mode
if that doesnt work run a scan in safe mode
if cant get into safemode at all,get a bootable erd commander 2007 and boot with cd,choose your windows installation if you see it and use restore option,if you dont see windows installation at all try backing up ure data if necessary using usb adaptor for hard drive n copy data to other pc nad re install windows

If you have a problem getting into safe mode using windows Vista or 7, boot up your computer. As soon as it tries to start windows turn off the power. When you try to start it again it should come up with a menu asking if you want to use safe mode or boot normally. Select safe mode.
