Sensible Android custom install

Recently I have gotten my hands into a Sony Xperia Z phone. Thanks to Sony, its bootloader can be unlocked, so it's time for some Android flashing.

My objective is to get an Android terminal as full of FOSS as possible, free of Google's eavesdropping, functional, and safeguarding my privacy. Why?

Right now they know your bank accounts, they read your mails, your chat conversations, log your messages and calls, your social interactions of any kind (and who is your friend); with the gps they know where do you sleep (ergo your home), where do you work, your daily paths; they know what do you like, dislike, you search for, etc.

In summary: they know things about you that you don't even know.

Do you remember how it feels to have one of those 90's telephones? the freedom, but at the same time the feel of being connected? It can be achieved within this modern times too!

Steps to follow

  1. Android ROM: CyanogenMod. Replicant is not supported for Sony devices so far.

    • download CyanogenMod, flash bootloader: fastboot -i 0xfce flash boot boot.img fastboot -i 0xfce reboot
    • install CyanogenMod from zip, with the bootloader. At this point there isn't any Google apps installed on the terminal.
  2. One can setup a CyanogenMod account, to be able to wipe and track the device.

  3. Privacy protection from apps: CyanogenMod has a privacy setting, under security->security in applications, that allows you to protect access to contacts, messages and call registers. Active it now so every app you install from now on has it activated by default. Anyhow, this protection sounds scarce. Apps should not access without permission to IMEI, SIM serial and info, network, list of accounts... that's what one would expect of a truly caged sandbox. This is achievable for example with pDroid. Also, CyanogenMod 10.2 will ship with Privacy Guard 2.0, which achieves some of those things.

  4. Grant root rights to CyanogenMod File Manager so you can see the external SD card.

  5. Google play substitutes:

- [1mobile]: for those (necessary) apps that aren't open source. It's a drop-in substitute of Google play, without the need of a Google Services account. Also, it allows you to install apps even if they aren't "supported" on your device (e.g: apps for 7" devices on a 5" device). You can install the market app from [http://www.1mobile.com/app/market/](http://www.1mobile.com/app/market/) .
  1. If you are going to install an ad blocker such as AdFree (from 1mobile market) or AdAway (from F-Droid), install it on the first place. That way apps would not make a cache of ads to show. In case of AdAway, you can add more sources to the host file from here: https://github.com/dschuermann/ad-away/wiki/HostsSources.

  2. Google contacts/calendar sync substitutes: synchronises your Android address book and calendar to CalDAV/CardDAV servers like ownCloud.

    • kolab-android: synchronizes your Android address book and calendar to Kolab/IMAP folders.
    • The Funambol Sync client: uses SyncML to synchronize your calendar and address book with various applications.
    • SSH Daemon dropbear: is pre-installed on CyanogenMod and can be used to e.g. run rsync.
    • birdieSync: paid one, 21 trial days. Syncs directly with thunderbird, no cloud needed.
    • aaaaaaand my favourite!! ownCloud. You can set up your cloud easily and painless. You can synchronise your Android address book and calendar to your own CalDAV/CardDAV owncloud server, and chose from a lot of apps to connect to it. UPDATE: look at my blog post for setting it.
  3. Now you can have all the Google aps from 1mobile, minus Google Now and Hangouts, which are tied to Google Services.

  4. Install all the apps you want. If you are using CyanogenMod app privacity settings, don't forget to allow your chosen apps to see your contacts!

  5. Using the CWM recovery, make a restore file and save it in the external SD card. This is what was called Nandroid before (called liked that because it backups the content of the NAND memory of an Android device).

  6. Since CyanogenMod includes Google Analytics, go to Settings->Telephone Info->CyanogenMod Statistics, and turn it off. If you don't feel good anyways, add to the hosts file (with AdAway for example):

    video-stats.video.google.com

    google-analytics.com

    analytics-api-samples.googlecode.com

    wintricksbanner.googlepages.com

    www.google-analytics.com

    www-google-analytics.l.google.com

    ssl.google-analytics.com

    googletagservices.com

    www.googletagservices.com

  7. ???

  8. Profit!

In the event that you feel the need of Google aps/services again, you can always install them from goo.im. Goo.im checks that the signing key of the Google aps matches the one from the Google Play Store. For obtaining your needed version you can look at rootzwiki, or install goo.im application from goo.im. If you prefer Gtalk instead of Hangouts you can download the Gtalk zip from here.
