    Android hacking problems solved: How to fix a bricked phone and more




    There are many benefits to be gained from hacking and
    modding your phone. But it can be a daunting process
    with a steep learning curve. Many users will find
    themselves following instructions without really
    understanding what is happening.
    To help you understand a bit more about the issues
    involved we’ve taken a look at some of the frequently
    asked questions users have about rooting.

    Will I still get OTA updates
    on a rooted phone?
    The answer to this depends on who manufactured your
    phone. Generally speaking, if you are rooted but still
    running the original, unmoved ROM then your device
    should still check and alert you to the availability of
    over the air updates. Installing them will very likely
    unroot your phone in the process so you will need to
    reroot afterwards.

    If you have modded your ROM, including relatively
    simple things like removing pre-installed apps, then the
    OTA update will probably fail. Reversing the mods
    should make it work again.

    If you’re running the Xposed Framework you will
    need to uninstall this from within the app for an OTA
    update to work. If you’re running a custom ROM you
    will have to install updates from the ROM developer.

    Can I install KitKat or
    Android L on my phone?

    If your phone is no longer getting official updates from
    the manufacturer then you can in theory update it to the
    latest version of the Android OS using custom
    ROMs. Older devices, or those with low-end specs,

    may not run so well, but most devices can be updated
    with varying degrees of success.
    There can be compatibility issues especially with older
    devices, since developers will need drivers for the
    hardware components of the phone, and if they don’t
    exists for that combination of component and OS then
    the developer will have problems implementing certain
    features, such as camera support.

    In some cases devices use processors that are no longer
    supported, so cannot be properly updated to newer
    versions of the OS.

    Unless you are able to build the ROM yourself you
    are reliant on your device having developers who are
    making the ROMs for you to install. Most mainstream
    phones will have a few devs working with them, and
    will be working on ROMs; the cheapest or most
    obscure handsets may not.

    To find ROMs for your phone head over
    to forum.xda-developers.com and search for your
    device.

    Can a custom ROM stop my
    apps from working?

    Apps that make use of DRM, or require a high level
    of security, such as banking and finance apps, will often
    not work on devices that have been rooted.
    There are some solutions that enable you to hide the
    fact that your phone is rooted, but these are by no
    means fool proof.

    Don’t forget that if you need to you can unroot your
    phone even while running a custom ROM.

    I’ve bricked my phone—how
    can I fix it?

    If you flash a lot of ROMs or mods then it is
    inevitable that you will brick your device at some point.

    A soft brick is generally not a problem. This means
    your phone turns on when you press the power button,
    but won’t boot. A hard brick, where the phone shows
    no sign of life when you press the power button, is much
    rarer and may not be salvageable.

    If your phone won’t boot after flashing a ROM the
    first thing to do is wait. The first boot after flashing
    can take in excess of ten minutes.

    Next, take out the battery or reset the phone by holding
    the power button in for ten seconds.

    Restart the phone
    and boot into recovery mode .
    Work your way through the menus to either reflash the
    ROM; wipe your data (not doing this is a very
    common cause of a non-booting ROM) then reflash; or
    restore the Nandroid backup that you should have made
    before you attempted to flash the ROM first time
    around.

    On many devices you can also use fastboot mode to
    recover from problems, including reinstalling your
    custom recovery if that has been wiped.

    Why do I need a custom
    recovery?

    Recovery is a small piece of software that runs on a
    separate partition to the Android OS.
    Booting into
    this partition enables you to access all parts of your
    phone, including the files in the OS.

    Recovery is used to back up or update the Android
    OS and its data.

    Every device comes with a recovery. The stock
    recovery is not a consumer feature so has very limited
    functions. A custom recovery, which is an essential part
    of the rooting process, can do a lot more, including
    flashing a ROM, creating a full backup, and mounting
    the internal storage or SD card as a drive.
    The two main custom recoveries are ClockworkMod
    and TWRP. They have different interfaces but
    largely similar feature sets; it doesn’t really matter
    which you choose. see ( http://www.gistpluz.com/2015/06/how-to-flash-custom-recovery-like-cwm.html)

    Do I need to clear the
    Dalvik cache and data when
    flashing a ROM?

    The dalvik cache is a cache of optimisations that makes
    your apps run faster (and will be phased out in Android
    L in favour or ART). You should always clear this
    when flashing a ROM.

    The data and cache contains all of your data, including
    your files, game save, text messages and so on. You
    need to back this up before you flash a ROM as there’s
    always a chance it will be lost if something goes wrong.

    Ideally you would always wipe your data before you
    flash a ROM. If you’re updating to new version of
    your current ROM then you probably don’t need to,
    but if you’re moving to a whole new build then you will
    definitely need to.

    If you don’t wipe and your phone won’t boot after
    flashing, wiping your data and reflashing is the first
    solution you should explore.

    Will rooting or flashing a
    custom ROM break my
    phone?
    The main thing when hacking your device is to follow
    the instructions closely.
    Make sure the ROM or mod is designed for your
    specific device before you flash it (and note that some
    devices have country-specific and international models,
    so make sure you’ve got the right one there, too).
    Also make sure that your phone is either fully charged
    or, preferably, plugged into a power supply before you
    start flashing anything.
    Rooting and flashing ROMs will likely void your
    warranty. In most cases you will be able to revert the
    process before making a warranty claim—Samsung
    devices being the notable exception to this.
