Install stock firmware, factory reset. You will lose ALL data and settings.

Yes, I also tried by factory reset. I cant explain exact issue, some virus/malware exist on my phone which makes my phone slow.
I tried many antiviruses but no luck so far.
So I want to format/repair/restructure folder/system files of phone so that infected files gets deleted from phone.
Factory reset and installing stock firmware is not replacing/deleting all folders/files of my phone.
Best Regards...

How do you know your phone is infected though? Factory reset + flashing already overwrites all your system files.....

okay, but your phone being slow does not mean it is infected. the prob might be with something else. maybe hardware?

How to fully reset device?

Dear SGS2 users,
I'm experiencing some problems.. The device is getting REALLY slow. When I try to open a picture taken with the SGS2 on the device itself it takes about 1 MINUTE before it shows the picture.. And opening SMS/Contacts also takes time.
I'd like to factory reset my device.. I tried a reset yesterday, but it didn't wipe any files, just sms/contacts. Can someone help me? I'm not rooted
Thans in advance

No it won't. But you should really try get a backup of it
But if you are using stock recovery and are unrooted, then you can wipe fine
Old stock ROMs did have an issue where they would not boot properly after a wipe, unless you re-ODIN the stock ROM again.

Put this code in your dialer:
*2767*3855#
This will do a complete rebuild of the device and wipe internal storage. So phone will be like when you first took it out the box! ;-)

Using avast! Hard Reset Protection

If I somehow brick my custom ROM and need to back up to a previous state, will this security app cause problems and not allow me to fix my phone?
Just wondering! Thanks.

I always used that,and never had a problem flashing roms (didnt turn it off before flashing)
i think it only stops say if you lost your phone, and somebody found it, and they did the hard reset option in storage (factory reset)
doesnt think it stops it at all at the custom recovery/ODIN level

Ah, that makes me feel a lot better. Thanks man.
But does that mean they could instead flash a backup or something onto the phone to bypass that "hard" reset?

yes, if a computer geek finds it you're done
but with sprint you can have them blacklist the EMEI
on GSM they could still use your phone

The only thing I can think to do is just restore your device to it's original factory settings/ROM as it will restore all the system files and hopefully restore your ability to use Bluetooth, then try rooting you device by using the one click root from towelroot.com, which hasn't caused me any problems what so ever.

Do i n just need to do factory reset or flash original rom?
And towleroot did'nt work for me?. Is' nt there a way where all my data does' nt get lost?
I would do both, first do a factory restore then flash the stock ROM and hopefully it will fix the problem. Towleroot worked for me, but I had to access the site and download the. apk file using my phone and to answer you last question when you flash a custom ROM all your data is erased, so you should backup your information before you, flash a ROM, or do a Factory restore it will make things easier.

Are you using a custom ROM? Custom kernel? Are you rooted? Have you unlocked your bootloader? We need more information.

I would suggest taking a backup and then do a factory reset and not restore anything. If that doesn't help just restore your backup. If it does work you could try to just install some apps at a time to try to figure out what made the problem.

I'm not sure. Did you make a clean install on all those Rom's? In case you don't know what that means, did you wipe data and cache between flashing them? If you did you could try flashing a factory image to see if that helps. If that doesn't help then as far as I know it is a hardware problem.

Find your firmware. If yours is G935A model, look for the PG1 fw.
Flash with Odin.
Literally only a few clicks away.
This will wipe everything so I'd suggest trying to see if you can save anything worth saving on your phone to a computer.

You'll need to either flash the stock firmware:
http://forum.xda-developers.com/att-s7-edge/how-to/stock-s7-edge-attg935aatt2apg1-firmware-t3431187
Or the "U-model" firmware:

Best is if you go back to AT&T and let them know about problem. They may replace your phone.

Don't listing to this guy. Your phone is rooted so your warranty is void and they won't do anything. Try a data factory reset in recovery first and wipe cache. It probly won't work but if it does it beats reflashing. Most likely won't work though. Your pretty much going to have to reflash it with Odin
I did this to mine as well deleting Samsung apps.
