Update Google Nexus 4 with LiquidSmooth Android 4.2.1 Jelly Bean Custom ROM

From the numerous Android 4.2.1 Jelly Bean based custom ROMs available for the LG Google Nexus 4 device since now, the LiquidSmooth software might be the most stable one, so you might be interested in trying the OS on your own handset. If so, I will be showing you in how to install the LiquidSmooth custom ROM on your Google Nexus 4, all the details needed along with the proper flashing operation being explained during the following lines. This is a complex tutorial and it will require all your attention therefore read everything and don’t rush things up.

The LiquidSmooth software is being based on the AOSP Jelly Bean 4.2.1 software which means that you will be enjoying a perfect Android experience on your Nexus 4. Furthermore, the update is coming with extra features and improvements that cannot be found in the default version of the Android 4.2.1 system; this is a custom ROM that brings an optimized and personalized Jelly Bean platform to your phone, so don’t expect to get a upgrade similar with your stock (official) OS.

According to our sources (those of xda-developers are being “responsible” for this) the LiquidSmooth custom ROM is working perfectly, as there are no bugs or issues into its system. So, you can update your LG Nexus 4 to latest Android 4.2.1 Jelly Bean software with no worries and with ease (this tutorial will be easy to complete though there are a lot of things to take care of) because the ROM will smoothly run on your device. But, before starting the step by step guide, you should check our source page for ensuring that this is what you need for your Google Nexus 4 (use the download link from below). Also, you can check our “update Nexus 4” section as there are more Jelly Bean powered custom ROMs released for your smartphone.

If you had decided that the LiquidSmooth is the suitable ROM for your device, then we should get started. Be aware as if you are not following my directions you can end up in bricking your handset. The first to start with are the pre requisites, which are being explained during the following list.

  • I recommend you to begin this tutorial with the classic backup operation. Unfortunately, by updating the LG Google Nexus 4 with a custom ROM firmware, you will lose all of your personal info. That’s why you might need to save the contacts, text messages, call logs, market apps and so on. For that, you can anytime use our backup and restore guides.
  • Then, the Nexus 4 bootloader must be unlocked. Furthermore, you should also root the system. This Android 4.2.1 based software will need to access some internal files and by unchaining the system of your phone, you will be able to grant that access.
  • The warranty will get void. Do not apply something on your handset without consulting the step by step guide first.
  • If you will need to, you can restore the lost warranty; you just need to re-install the stock ROM, or flash an official update to your Google Nexus 4. Of course the root access will then be revoked and the bootloader relocked but at least you will have the warranty restored.
  • Install a custom recovery image on your device. Without tool we won’t be able to apply the Jelly Bean update on your phone.
  • By using the mentioned recovery image it is recommended to make a Nandroid backup before performing the update operation.
  • As usual, you will have to use a computer for downloading the proper files.
  • For being able to do so, you first need to deactivate the Firewall and antivirus protection from your PC (also do the same on your Nexus 4).
  • Go to your phone’s settings and from there enable the USB debugging option.
  • Just before applying the LiquidSmooth update, charge the battery of your LG Nexus 4. Else your handset might get turned off right in the middle of the operation and you will risk in bricking it.
  • This tutorial must be performed only by those who own the LG Google Nexus 4 smartphones as the Jelly Bean 4.2.1 based custom ROM can be installed only on the mentioned device.

How to Update Google Nexus 4 with LiquidSmooth Android 4.2.1 Jelly Bean Custom ROM Firmware

  1. As already stated, on your computer use this link (is also our source link) and download the update file.
  2. Now, you must use the link from here and get the Google Apps. The package is not included in the update, so you will have to install it afterwards.
  3. Next, you need to connect the phone with the computer because the downloaded files must be transferred on your device.
  4. After placing the files on your handset, unplug the USB cord and turn off the device.
  5. The custom recovery image must be entered now.
  6. For that reboot by pressing and holding the Volume down and Power buttons together. From the bootloader mode that will be displayed, just select “recovery”.
  7. Now, from the recovery image first of all wipe the system; you can do this by selecting “wipe data factory reset” and “wipe cache partition”.
