Update Nexus 4 to Android 5.0 LNX07M Lollipop Developer Preview

Google took a huge leap when it released Android 5.0 to the public and bought tons of new features and additions with it. It was released as a preview officially, for the Nexus 5 and the Nexus 7. The sole purpose of this preview was not only to showcase the upcoming Android version, but to build a stable version of Android, with the help of its users. This way, everybody could prove itself to be a part of it, which in its own way is a huge accomplishment.

Nexus 4

Here at XDA Developers, are aiming in porting the same to our beloved Nexus 4. Since, the beginning of the trials, a lot of errors were tackled and resolved with pure dedication of both, us (developers) and the users. The teamwork has resulted in creating a near-perfect port for the Google Nexus 4, which is highly voted to be used as a daily driver.

After a long thought, XDA Developers have decided to split the project into two different parts. The first one is based off of Nexus 6 dump (LRX08) containing the complete N6 framework and apps (S-builds). The second one is based on the latest official Nexus 5 preview image. This is being done for a better user experience because some users prefer the N6 framework and apps, giving the latest Android Lollipop experience, and others like to follow a more close-to-google walkthrough given by the N5 preview image (P Builds).

Backup and some important tips

Done with USB Driver? Good. Now here we go for some work that you must do before installing this firmware. Please follow the important points that you need to take care of, as we don’t want anyone losing their personal data or apps:
Backup your all important data and apps because during any installation of a new custom ROM or Official Firmware , your device will be wiped and cleaned with new operating system. Make a backup for just in case, you never know when anything might go wrong. Read below for some important tips on how to backup Android data in a easy process:
Samsung user can also backup data by using Official Sumsang Kies. If you backup data manually, you will get more options for what to choose from. You can also move your data to other Android devices from different manufacturers, i.e moving Samsung Galaxy S5 backup data to Google Nexus 10. 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.

Few more important things that you must remember before installing any custom ROMs or Official Firmwares:

  • You might face some problems in connecting your Android device to the computer. How to fix? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich and KitKat.
  •  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?
  • Most of the tutorials and how-to guides on iDroid Horizon are for factory unlocked Android devices. We recommend NOT to try our guides if your device is locked to a carrier, unless we have specified the device model or carrier name.
