Backup and Other Important Tips

Done with the USB drivers? Perfect. The tutorial is on the next page, but first, 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. See below for some tips on how to backup data:

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. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean and Lollipop.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. 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?

4. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend not to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

  • Do we have a modified kernel for this latest build? I tried the steps outlined here, but I still get no root access. SuperSU says “there is no SU binary…”

    • You need to flash the CF-AutoRoot image by Chainfire. Download it and copy it to the same folder as the fastboot file. After following all the steps in the post above, reboot your Nexus 5 into Bootloader/Fastboot mode and run this:


      fastboot boot CF-Auto-Root-hammerhead-hammerhead-nexus5.img

      Root should work now.

      • Hey, I had that problem too and I did what you said and it fixed it!

        but I have a problem with titanium backup, when I launch it and it grants root permissions (it does) and it says:

        “Sorry, I could not acquire root privilieges. This application will *not* work! Please verify that your ROM is rooted, and try again.

        This attempt was made using the “/system/xbin/su” command”.

        I have rooted LRX21O with ElementalX 2.03 kernel stock rom.

        • I had the same problem yesterday. The version of Titanium Backup that was on Google Play yesterday was not compatible with Lollipop. They have just updated it so you probably already got the updated version. I manually installed their test version last night, which also worked.

    • I just used the modified kernel for the developer preview. It worked. I hope little if any has been changed between the dev build and the release one…

  • Just use Wug’s Toolkit.He just updated it to 1.9.4 and it now fully supports Lollipop 5 latest firmware and it does all you need automatically.It uses modified img’s offcourse like Furst well said.May the force be with ya’ 🙂
