Backup and Other Important Tips
Done with the USB drivers? Perfect. Now please take a look at the following tips and important
points you need to take care of. These are important, as we don’t want
anyone losing their personal data or apps:
Always backup your important data that you might need
after you install a new custom ROM, an official software update or
anything else. Make a backup for just in case, you never know when
anything might go wrong.
- Backup your Apps.
- Backup your SMS messages.
- Backup Contacts, Gmail and Google Data. How? –> Sync with Google Sync.
- Backup Call History.
- Backup WhatsApp Messages.
- Backup APN Settings: GPRS, 3G, MMS Settings. How? Note down
everything from: Settings > Wireless & Networks (More…) >
Mobile networks > Access Point Names.
Samsung users can also back up data using Samsung KIES.
If you backup data manually, you get more options what to choose from
and it is very easy to move data across Android devices from different
manufacturers, i.e moving Samsung Galaxy Note backup data to HTC One X.
If you already have a custom recovery (ClockworkMod, TWRP etc.)
installed on your phone, we strongly recommend a backup using that as it
creates a complete image of your existing phone set up.
A few more optional tips that you should remember:
1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode.
2. Make sure your Android device is charged up to 80-85% battery level. Why? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
