How to Root Samsung Galaxy Note 8.0 GT-N5100

Hello All,

---

Few days back my Note 8.0 entered into Factory Mode. A transparent yellow panel superimposed upon the “home” screen with a list of hardware information. Although i was able to access any application easily installed in my TAB but i was not able to restore factory settings/clear cache etc, Power button options were also missing on doing ON/OFF tab.

Factory Mode:

Earlier i was not having any idea about this Yellow screen box so i went to Samsung Customer Care Center and showed my TAB there. I was shocked when an executive took my tab and entered 10-12 alphabets in TAB then suddenly said motherboard is not working and it will charge around Rs 7000.

So this research started from here. I had a conversation with executive. Why and how it can be possible that mother board is not working but TAB is getting ON/OFF. And Executive was very sure that motherboard is not working.

I came back, opened my laptop and thought to google it. After searching it again and again i get to know that my TAB that it is entered into FACTORY MODE. It happens due to EFS corruption. So let me tell you what i did to make my TAB come out from this MODE.

Here is the solution for this problem which i have had:

1. You have to root your phone and install Terminal Emulator from Google Play.
2. Open terminal emulator and type as ;
su
rm /efs/FactoryApp/keystr
rm /efs/FactoryApp/factorymode
echo -n ON >> /efs/FactoryApp/keystr
echo -n ON >> /efs/FactoryApp/factorymode
chown 1000.1000 /efs/FactoryApp/keystr
chown 1000.1000 /efs/FactoryApp/factorymode
chmod 0744 /efs/FactoryApp/keystr
chmod 0744 /efs/FactoryApp/factorymode
reboot

You will not see that message anymore. It will also bring back the lock screen and power button options.

Please provide your valuable comments and suggestions. Thanks
