Rooting a locked android phone

    As above really.

    I have an O2 locked Sony xperia sp which I would like to put android 4.4 on.

    I have read various articles on rooting it, but none of them either make sense or in the case of one I tried worked. Some lead to websites that won't let me download the rooting kit or if I can get it to download, then informs me it is not for that phone despite me having checked it was the correct phone, android version and phones firmware...

    I appreciate that the kits are specific for unlocking and rooting, the phone is on 4.3 which on my phone had been very unstable crashing at midnight unless I turn off network operator time synchs and is really bad for a flickering screen etc.

    Had anyone any experience of rooting the phone that can guide me please? It is outside its 1 year warranty but not fully paid for yet - another 9 months to go on that.

    I did root a old Samsung S2, without any problems, but that was a couple of years ago,
    I just had a look on google and found this website, which might help

    Have a look at this link

    The best place for that is xda developers. I've rooted a handful of phones now without any issue. All have also had the operator lock removed too!

    Well, I haven't experienced anything like this before but I can understand because there are a number of junk thread available which may be the reason why things doesn't moves like the way it should at your case but anyway but what need to do now is flash the stock ROM again over to your device and then again trying rooting things !

    The phone has been rebuilt. I am considering my options at the moment. My laptop needs to be rebuilt and tbh some of the instructions for flashing the phone are not obvious to me at least. Please beat in mind that until a year ago I didn't have a smartphone and it is only in the last 3 years I have even had a mobile phone because I used to live and work in an area that had no signal and cycling to and from work also had no signal...

    The one that starts install the fastboot drivers leads to an inf file. Install where? Phone or laptop (windows 7 64bit) and do what?


    I'm happy to kill the laptop. It had to be rebuilt son, I just keep putting it off because well I hate rebuilding it (stems from rebuilding easy too many at work and not wanting to do my own).

    Talk about wanting to scream!

    So I have finally found out where the driver is meant to go.

    You have to install the android SDK package first.
    But to do that and get it to work, you have to install Java SDK as well.
    Then you run the installation for android SDK again to be informed that it can't find the Java SDK installation and it wants you to manually point to the required file which is not in the folder suggested
    Then the program runs after a very slow installation and informs you that there is an update but before you can do that there are over 1gb of downloads it must do..
    Then you update and still find you don't have the required file to replace because you haven't yet run the SDK manager which unsurprisingly wants another 9 packages to install one of which is actually the package that has the file in it that you need to replace...

    And I still need to root my phone.

    On the interesting side, I have finally established where the developer tools are on Jelly Bean (4.3).. You have to go to settings, then into about phone, then scroll down to build number and keep tapping it repeatedly until a count down arrived and then keep tapping until the count down informs you that the developer tools have been enabled. After this you can go back up one level and you will now see that you have a new level called developer tools, so now you can go in and enable USB debugging.

    I am seriously wondering if it is worth upgrading from android 4.3 to 4.4.4!

    Oh and I have established that my phone cannot be unlocked by entering a long code into the dialer (*#*#7378423#*#*) which brought up a new menu going into service info, configuration, routing status and reading the boatloader unlock option sadly said no!

    This comes from http://developer.sonymobile.com/unlockbootloader

    Right, I have finally tracked down the file that needs replacing.


    OK, I feel better now.

    Every article I've read has said rooting your phone is not for the faint of heart... Also I'm not sure lollypop is really that good yet. I have the Moto G which should be one of the first to get it and it's not rolled out to my device yet. You are probably better of installing a rooted version of kitkat than lollypop, depending on why you are rooting it...

    Best of luck. Think I'll be trying mine soon, the phone is getting slower with every goggle and Motorola app update and I want the speed back...

    ah, upgrading to kitkat is worth it, if rooted.

    lol, indeed my phone keeps goggling rather than googling...

    It is currently getting the better off me. Calling it a day, yet again. All the instructions seem to be either 5 years out of date or include software that says it is only for version 4.0.4 of android! Ahhhhhhh

    PS does anyone know why the KitKat ROM is meant to be left zipped and on the SD card?

    ahhhh - well I have managed to root my phone quite easily with towelroot.apk but it turns out that my phone can't be unlocked, so none of the kitkat updates are available to me because they all require an unlocked bootloader and mine can't be unlocked, so it seems... at least not according to sony and putting that code in to it!


    now to rebuild the laptop to get all the crap off it!

    Ah, that Sony love of locking things down. Shame but a learning experience...
