Android 4.2.2 AOKP Build 4 Jelly Bean Firmware Details:

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:

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

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.

All set and ready? Good. Now, let’s proceed with the tutorial below and update Droid 3 XT862 on Android 4.2.2 AOKP Build 4 Jelly Bean firmware.

    I realize I’m coming at this rather late, but I need some advice. I picked up a Droid 3 on eBay, and I would like to bring it forward in time from gingerbread to at least Jellybean. I managed to work around the broken links in this tutorial, I’ve gotten all the files I need downloaded and onto my SD card, and my phone is rooted and ready to go. But I can’t get ClockworkMod to function. It opens, it says its doing things, but it will neither make a backup it can find afterwards, nor will it reboot into recovery mode. The phone just restarts normally. Any suggestions? Note: This is a Verizon phone, although I have switched carriers with it. (It still has a Verizon SIM card installed, and half of its Verizon apps are still there. But I have service thru Straight Talk.)
