I need answer for some questions???

[santhire]

I have rooted my device
I don't know it's rooted fully or half how can I check it???
When I tried to replace framework-res.apk my device reboots why???
Replacing these apk needs to unlock bootloader???

Thanks

Simple, install an app that require root access and check if it works. 

[santhire]

It is working
Then why is that reboot when I replace framework-res.apk??

*Whether your root is full or half, it depends on the method of root you used.

*Unlocking bootloader is only necessary when you need to install any custom rom.

Otherwise rooted phone can function fully with the locked bootloader.

*Framework-res.apk is used to tweak your phone's appearance.

However, manually changing it can mess your phone.

I would suggest that install Xposed Installer, then download modules using xposed installer and you can use these modules to tweak your phone.

Use Towelroot to root your phone. Then run remountfix. This is to rectify the reboot issue. Once run, your rooted phone wont reboot.
