Update Google Nexus 7 to Liquid Jelly Bean custom ROM
The Google Nexus 7 tablet has just received a brand new custom ROM that is based on AOSP Android 4.1 and now you can use the instructions that I have listed in this post to learn how to install it correctly. Read the entire post and only after that you should proceed to apply all the changes. Also, remember that this update is only for Nexus 7 and it is an AOSP-based release that packs several CyanogenMod features and it has been named Liquid custom ROM.
Liquid Jelly Bean custom ROM is based on the Android 4.1 stock firmware and it brings multiple new customization features, new apps, improved notifications bar, new lockscreen targets, a better UI etc. Before we can begin to flash this update you should read the preparation guide and learn what steps you need to take in order to correctly apply all the files.
At the moment, this new ROM is in alpha stage and it might be packing some bugs and you should create backups before installing it. Read the guidelines below and the extra info so that you’ll learn what steps to take before moving to the tutorial. Here’s what you need to know:
- this tutorial works exclusively with the ASUS / Google Nexus 7 tablet device and you shouldn’t attempt to install it on other Android devices.
- to correctly install this new ROM you will be asked to wipe the data. This means that you should move all important files on your device’s Sdcard as this one won’t be wiped during the process. The data removed will be the installed applications and other files.
- it is recommended for you to create a full backup of the existing ROM so that in case you don’t like this Liquid Jelly Bean custom ROM then you will be able to restore the one that works.
- if you wish to backup apps and the APN Settings, then you should use the following applications: AppBAK for Android apps backups | APN Settings Backup & Restore.
- The Google Nexus 7 should be rooted and CWM Recovery has to be installed on it. Also, all these are working only with a Nexus 7 tablet that has its bootloader unlocked. If you don’t want to use CWM Recovery then you can flash the TWRP Recovery project.
- Enable USB Debugging option for your tablet device.
- Charge the tablet’s battery so that it won’t be disabled during the updating process.
- Install this update only if you’re an advanced Android user as you might end up bricking it. Read the entire post and make sure that you don’t skip any steps I’ve listed as that might end up in bricking your device.
This update will install the Liquid Jelly Bean custom ROM and you should try it if you’re an Android enthusiast and Google Nexus 7 owner. It will improve the phone’s performances and since it packs several CyanogenMod functions you will get new customization features that will allow you to set and configure the phone’s just the way you like it. Make sure that in case you cannot update your tablet with the instructions I’ve listed in this post, you will use the comments section to post all your questions.
Now that you know all of the above you should move to the tutorial guide and learn how to successfully install this new custom ROM on your tablet.
Install Liquid Jelly Bean custom ROM on your Google Nexus 7
- Download the Liquid ROM zip file HERE and save it on your PC without extracting its contents.
- Now connect your tablet to your PC and move the ROM zip file on its internal SD card.
- After the transfer is complete you should unplug the device and then power it OFF.
- Boot into CWM Recovery mode by pressing ‘volume up’ + ‘volume down’ + ‘power’ buttons at the same time. Hold them like that until the ClockworkMod screen appears and then move to the next step.
- Create a Nandroid backup of the existing Nexus 7 ROM by selecting ‘backup and restore’ option and then select ‘backup’ and wait for the process to complete. If you already created a full backup of your ROM before moving to the tutorial then you should skip this step and continue with the Liquid custom ROM install process.
- Select ‘wipe data/ factory reset’ option and after that, when the next screen appears you should confirm this process. Wait for the data wipe process to complete and after that you will be able to flash the Liquid Jelly Bean ROM. If your tablet uses TWRP Recovery then you should select ‘Wipe’ and then ‘factory reset’. After the data is deleted you should return to the main recovery screen.
- Select ‘install zip from sdcard’ and from the new menu select ‘choose zip from sdcard’. Find the Liquid ROM zip and install it. For TWRP Recovery users, select ‘Install’ and then find the ROM and install it. After the installation is complete you should return to the main recovery menu.
- Select ‘reboot system now’ and now your Google Nexus 7 will reboot into normal Liquid Jelly Bean custom ROM home screen. If this first boot process cannot complete the restart then it might have been bricked and this means that you will have to repeat the entire tutorial once again, but, after you remove the battery, then re-insert it and boot again into custom recovery mode.
- If everything went according to plan then you should enter your Gmail account details and get control over your phone.
