I cannot emphasize this word enough, “backup”. If you have just rooted your LG G5, the first thing you should do is make a backup. In fact, make a backup of everything before even rooting, backup all your personal files, photos, videos, etc…etc… If you absolutely have no need because you have nothing important on your phone, did you know you should still backup your stock firmware?
In fact, you should backup your stock firmware, modem, and EFS then put that data somewhere safe just in case you want to restore your LG G5 later down the road when things go wrong. Of course, you can always use our unroot guide but backup ROMs can save you the headache of starting over from scratch.
Backing up using TWRP recovery is easy as pie and you can use an OTG cable and USB flash drive to save all your backup ROMs so it won’t take up your phone’s storage space.
Especially for those of you who are rooting your LG G5 for the first time, having backups of all your stuff can save you time and money in the long run.
Okay, but how to backup stuff?
First, backup your ROM using TWRP recovery, which will backup everything on your phone except for personal files like photos, videos, and documents.
Next, backup all your personal files by simply copying them to another source such as your desktop computer or you can even use an OTG USB flash drive.
Third, use Titanium Backup app to backup all of your apps so when you install a new ROM or switch to another phone, you can restore your apps easily within minutes instead of starting over from scratch. This will also save all your app data such as Level 300 on Angry Birds or perhaps important app with all your work.
