[ROM][Nexus 7] Jr12 **WiFi** (JOP40D / 4.2.1): MoDaCo Custom ROM for the Nexus 7

Thursday, 13 December 2012



I'm pleased to present my MoDaCo Custom Jelly Bean ROM for the WiFi Nexus 7! READ THIS WHOLE POST BEFORE YOU START! No, really, it contains everything you need to know. 

About MoDaCo Custom ROMs

MoDaCo Custom ROMs are based on official ROMs. A MCR release is designed to feel like a stock ROM with optimisations, tweaks and complimentary additions that enhance the user experience. The aim of a MCR is to be ultra reliable for use on an everyday device.


In order to use this ROM you must have a custom recovery installed. The ROM is installed at your own risk. A wipe IS recommended if coming from a ROM other than MCR or stock. BACK UP YOUR DEVICE BEFORE INSTALLATION!

MCR Nexus ROM features Include... (many optional via the Online Kitchen) - check kitchen defaults for what is in the prebake:
  • Based on the 4.2.1 / JOP40D release, updated, rebuilt, compressed and optimised with the MCR build system.
    For this MCR we've used the latest available shipping ROM, updated with all the latest versions of the installed apps, which we've run through our scripts to ensure that it is as optimised as possible both for install / download size and real life performance.
  • De-odexed... re-odexable.
    Our ROMs are de-odedex, giving you the ability to flash other mods over the top, tweak the system and generally get the system set up as you want it without worrying about odex issues. We also include the 'OdexMe' application, which lets you odex your system when you're ready, saving valuable space on your data partition.
  • Pre-rooted
    All MCR ROMs are pre-rooted with SuperSU preinstalled. In addition, the kitchen allows you to choose between secure, insecure and secure with patched ADB boot images.
  • Enhanced Quick Settings
    The quick settings in Android 4.2 are cool, but limited. MCR builds include a customised version of the excellent 'Quick Settings' mod by kevdlui, allowing you to customise your toggles by holding the Settings button down. The WiFi and Bluetooth buttons are also changed to toggles - long press to access the settings menus.
  • Enhanced Power Menu
    The enhanced power menu (the one that appears when you hold down the power button) has additional options to allow you to reboot and reboot to recovery.
  • Apps aren't disabled on boot
    Jelly Bean added a feature to disable apps on boot that aren't intended for your region (Wallet, Ears, Magazines etc.). I think we're smart enough to make that decision ourselves right? So that doesn't happen in a MCR.
  • Legacy Play Store
    Isn't it frustrating how Google removed the ability in the Play Store to see which apps you'd bought in a nice simple list? I thought so... so I created 'Legacy Play Store', which has this feature.
  • Legacy browser and Flash
    Google might be ditching the stock browser for Chrome and Adobe might have canned Flash, but we still need to use it sometimes... so it's included in a MCR.
  • Patched Google Wallet
    We've patched Google Wallet to remove all region and root checks, so you can have a play!
  • Facebook sync support
    Google removed all support for syncing contact information via the Facebook app, we put it back. It's basic support (an app like HaxSync is more fully featured) but hey, it works!
  • init.d support on boot
    The init.d directory is processed on boot, allowing our (and your) startup script to be processed before the system starts up.
  • Alternative appstores (Amazon and SlideMe Market)
    The Amazon and SlideMe stores can be preinstalled, if that's where you like to purchased your wares.
  • 'TweakDeck' - Tweetdeck, fixed
    Tweetdeck was great. Twitter ruined it. It's fairly comprehensively broken on Android, but we've fixed it with TweakDeck.
  • Titanium Backup preinstalled
    Once you've flashed your ROM, if you've wiped you want to get your stuff back on as quickly as possible - the option to preinstall Titanium Backup is here to help!
  • MoDaCo Boot Logo
    Wear your MCR with pride with the MoDaCo boot logo. It can be disabled in the kitchen of course if you prefer the more subtle look.
  • And there's more!
    We haven't listed everything here because a) there's too much and B) there's things we've forgotten. 
MCR Nexus 7 ROM specific features Include... (many optional via the Online Kitchen) - check kitchen defaults for what is in the prebake:
  • Alternative UI options (clickable when hidden menu keys with alternate locations, search button)
    A number of different UI options are included - the default option makes the legacy menu button available on both sides of the screen for easy reach and also keeps them active when invisible, handy if there's a pesky menu button at the top right that you can't quite get too! You can also bring back the good old search button. In stock Android the navigation bar always stays at the bottom - in the kitchen you can choose to have this move to the right. Finally, percentage battery meters are also included in stock style and round style.
  • NFC on screen off
    If you use NFC tags to set profiles or similar, then the option to enable NFC on screen off might appeal to you. Be aware that we haven't benchmarked the impact this may have on battery life as yet though!
  • Stock Launcher with rotate support, Nova and Apex Launchers as options
    The stock launcher, with support for Landscape. So simple! If you're an Apex or Nova fan however, you can choose these to be baked right in to your ROM.
  • Camera Launcher
    In their infinite wisdom Google removed the Camera icon from the Nexus 7 - we put it back!
  • Disable camera shutter sound
    You can disable the camera shutter sound - use responsibly!

Please see the post below this one for the changelog.


To install this ROM:
  • Download the zip file of your choice from the links below (or the online kitchen) and copy to your sdcard.
  • Restart your device in recovery mode
  • Select the option to apply an update zip, and select the zip file you copied to the internal sd card! Remember that due to the 4.2 user changes, you may need to change to the '0' directory in recovery to find the zip!
If you have problems with Market licencing, check your device date!

First boot may take a while - be patient while it carries out it's pre-dexopt. It's worth it!

It's impossible to mention everyone who contributes to the Android community by name, but to everyone out there who does great work and shares it with us all - you have my gratitude and respect.

Future Updates - READ THIS!

By providing this ROM I am not guaranteeing that future updates will follow. Due to limits on my time and the fact that I have a large number of devices for short periods of time, it isn't possible for me to continue providing ROM updates indefinitely. Please do not donate / sign up on the assumption that future releases will be available (I don't want you to be disappointed!).

And finally...

Details on how to donate should you wish to do so are in the download topic at MoDaCo.
