Thanks for the advice Bro. Sorry but need to ask how do I wipe data cache and dalvik? Can I do it on the phone?
And when you say Nandroid backup, what will it actually backup?
If say I just flash over my LG8 now, will I lose any data or apps?
Sorry for the many questions. Still new at this

Does your phone rooted and have CWM recovery..?
If you have CWM recovery then you can do Nandroid backup via three buttons combo (vol up + home + power button).
Once you on CWM recovery > backup and restore > do your Nandroid backup.
For wipe > CWM recovery > wipe cache partition
Then go back into CWM recovery > advanced > wipe dalvik cache.
I think you will lose your app and data..so better do Titanium backup for your app and data. After flashing download and install back Titanium app from market then you can restore back all your apps and data.
Good luck
