[SOLVED] Rooting Issues

hi
clearly this wasn't as simple as the unrevoked method for my last phone,
I ran the script 'root many phone' and it cracked on whilst moaning about permissions and by the time it had finished the phone restarted a bit broken.
It had not play store, none of the previous apps on, wasn't actually rooted at all.
I managed to get play back on there but installing via adb.exe from the command line, and its almost like when I install something, that was on there before, it still has all the settings, so not quite sure what has gone on.
can anyone offer some advice, is it simplest to somehow get myself back to stock and start agin.
maybe I didnt run the root script from the right place. - phone was on and plugged in , usb debugging enabled.
any help much appreicated

I don't know of starting fresh is the 'best' option, but if you haven't done anything that you can't miss our can't do again it's never a wrong try.
Some people also reported that you need allow test locations on. And allow installation of external apps must also be set.
You can always try re rooting without reinstalling.
If you want to reinstall you're best of using Sony update service. Googling is fastest way to find it (not Sony pc companion)
Good luck,
And don't forget to mark your thread solved if it is solved

hi
yes that was what I tried
do I need anything more than that script? (eg those ftf files i keep reading about?)
does the phone need to be on, or in the volume down on boot state
it appears I need 'test locations' and 'external apps' set
anything else I need?
i will try again today at some point
thanks

sure I am being a spanner, but I cant even find the test locations or external apps setting anywhere?
where might that be?
unless test locations is 'mock locations' (guess so)
stilll not finding the external apps option, thought it would be in apps setting somewhere..?
ok found that too in security > unknown sources.
ignore me

That root script didn't work for me either; it kept asking me to connect my device with USB-debugging enabled even though I had already done that.
I would suggest getting back to stock and trying again, BUT use FlashTool instead. It worked perfectly for me in mere seconds.

I downloaded version 0.9.0.0 version, but no XperiaT in the list when I plug it in..
which phone did you pick?
presume the steps are
1. download flashtool
2. Install it on your PC
3. Run the Flashtool and connect your phone (enable USB debugging first)
4. Hit the Root button (second in row)
5. When you see "waiting for restore to finish" open your phone and run Backup&Restore app and restore RootMe.tar file.
6. Wait until Flashtool do the rest of work
thanks

If you mean in the adb drivers list, select Xperia TX. That was the only time I had to select a device.

OK finally success
although using the initial method.
maybe the problem was created by reading the 'root many phones' thread and where it says there is a special case for Xperia T/S etc I took that to mean when running the tool, to pick option '2) special case Xperia S tablet etc' - which didn't work
ran it again picked option '1) Normal' which did work
thanks for all your help
nat

Not necessarily relevant to the OP's problem but I thought I'd share in case it helps anyone else out...
When I tried rooting using Bin4ry's method I kept getting a adb server out of date error and the root failed.
I eventually traced this to having DROID explorer installed which was forcing an old version of adb to be running and stopped the newer version from starting up.
Once I uninstalled the old version I was able to runMe and root the phone.

[Solved] Stuck at Sony logo : Assistance needed and welcome

Dear Members and Expériences user,
My XZ is stuck at Sony logo:
How it happened:
Phone was Roted
Locked bootloader
Recovery installed
Using stock rom with pureaudio
As my phone was always running Multimedia process making it So hot and following users advices (perhaps due to a corrupted image) I have performed the folowing:
1- boot in recovery
2- backup phone and reboot
3- backup everything using titanium backup
4- transfer all backup from internal memory to sd card
5- Eject sd card
6- performed a wipe and factory reset from settings
7- reboot and configure apn and accounts
8- reinstall superuser then titanium backup apps
9- reboot
10- restore some apps (mainly games) and some systems settings (only sms/mms and phone call history)
11- as advice by TB reboot
12- bootloop...bootloop...
13- boot in recovery
14- restore (using advance fonction) system only
15- went off battery (I did not notice that my kids unplugged charger)
16- Here i am...
Please help me
--------------------------------------------------------------------------
Here the procedure I have applied:
--------------------------------------------------------------------------
First a Huge Thanks to :
- diego9016
- LitoNi
Which guided me on the solving.
As proposed, I have :
1- Installed the Sony PC Companion 2.10.155
2- Installed the Flashtool-0.9.10.2beta6 --> Thanks to Androxide for that
http://forum.xda-developers.com/showthread.php?t=2162907
3- Followed the Tuto of 'Flashing Stock Rom with FlashTool --> Thanks to Shadowboy23 for that
http://forum.xda-developers.com/showthread.php?t=2240614
3- Used the UK Unbranded FTF --> Thanks to Paulkhim for that
http://forum.xda-developers.com/showthread.php?t=2221475
I have followed line by line the différents tutos and it worked out very well.
The only thing I did differently was running the the flashtool as admin user when it succeed.
Thanks to all and good dev for the XZ which it deserves it.

Of course... But first, you need to charge your phone.
Follow this tutorial, it should bring back your Z to life.
Here you can find the ftf you need.
Just be sure you have the C6603.

I have tried and unfortunatley no success
Everything runs well until when the phone has to be connected to the PC while holding the Vol Down Button.
Then the Device seems to be connected and after a while it deconnects and restart itself and locked at the Sony Logo.
Then the flashtool recongnises it as disconnected
:crying:
Any other test I may perform ?
Thanks for your patience and support

Do you have the flashtool drivers correctly installed?
Have you tried restarting your pc and see if it works? Don't open PC Companion or any of the other Sony software.
Are you connecting the device powered off and holding vol down?

One more question when to unpress the vol down button ?
I performed it when the Windows displayed Device Connected in Flashmode, Am I right ?

Thanks for the advice.
Does it takes long cause I stayed like 4-5 mins by holding it without seing any progress bar and soon I unpress it the phone restart by itself and back again at the Sony logo.
To switch it off again I have to hold Power + Vol Up and Down during 5-10 sec until it vibes 3 times.
Is it the right process ?

Just fyi, your main cause of this is most likely when you tried restoring the apps.
Do not try to restore them with titanium backup Or cwm if you are moving from one rom to another etc... To avoid any issues like this one.
Backup and restore using whatever the app provides. Their files are usually located internally. ( just drag it to your comp)
Before starting flashtool, hit the arrow icon (where more hidden programs are running) you may find pcc or sus running sometimes after you reboot your computer.
Find the right ftf file, make sure you are using the most updated flashtool.
Good luck man.

Not saying you can't, but why should you have to rehash information they could have found themselves, but I guess this is what xda has become these days.

Ok, here´s the process:
Start flashtool, select the ftf and start the process... Flashtool will say Preparing Files for Flashing. Then, a window will prompt and tell you to put your device in flashmode.
With you phone turned off and unplugged, leave vol down pressed and connect it to pc until the window disappear, that's the moment you release vol down button and flashing process should start.

Add to that I don't know did you do this yet but I'll mention it anyway:
Before you start flashtool
1- go to settings of your device > developers option (enable it) scroll down and check usb debugging.
2- not sure if you need to do this but might as well cause I do it all the time. Phone settings > security > check unknown sources.
Go ahead and start flashtool and follow the instructions before this post

Thanks a lot for your support :good:
By not being alone I kept the head out of the water and finally succeed.
To make it short, it seems that the FTF file was a kind of corrupted (unable to check the MD5 Sum cause not provided), nevertheless I download another FTF file from another country (I selected UK as I can easely read UK than others languages) then on the second attempt it finally went well.
I do not know the effect of flashing another country Stock firmware yet, but I think as for the cooked rom it does not creates big issues.
Thanks again to supporting me on this tricky situation.
And as promoised after this answer, I will write down what I have performed.

Thanks for your answer, As I was blocked on the start of the phone, it was not possibe at the time being to change the settings (perhaps I were Lucky cause these settings were as you proposed before my issue happened).
I will learn more on the SUS and SPCC as I do not know so much on the Sony tech and apps. (Was an HTC addict for years until this one XZ appears and make me change).
Thanks for your support also.

You wont need to root for flashing :good: don't worry go ahead and happy flashing
PS: Take a data backup as clean flash will wipe all data

I changed my config number to get generic US FW because my phone was running indian FW. Basically if you root, you can modify some text in a configuration file and trick the phone into thinking it's a model that it really isn't. More info here:http://forum.xda-developers.com/xperia-z/help/how-to-change-si-sony-xperia-z-t2271530
Root is also super easy - Google towel root, it is a recently discovered exploit that allows for one click rooting more or less.

Where can I download drivers for a Sony Xperia Sp

to include in the drivers directory before I use Flashtool to try and get my phone up and running. I am having the same problem as many of the other Xperia Sp phone users on here that have a phone that will not turn on no matter what you try, and that the LED blinks red twice every time you try to press the on button. And pressing the yellow reset button seems to do nothing for it either. I have downloaded the Flashtool application already, I have downloaded my Xperia Sp's version of firmware, and I am now charging the phone for 24 hours. I just do not know where to find the drivers to include in the driver's directory, since I can not get the computer to recognize that the phone is actually connected to the computer. Any advice as to where I can download the driver's for this phone or even what they are called, then I could probably find a copy of them through the internet on my own, but as of this time I do not even know how they are labelled or what they are called.My Sp's Model # is the C5306. Thought including which model it is might be important since there is 3 different models of the Xperia Sp.
Thank you for any help and Assistance anyone might be able to give and for your Valuable Time

I can guide you if you can install Ubuntu. Flashtool is available for Ubuntu and it works buglessly. I, too, was unable to run it on windows due to some driver related issues but Ubuntu runs it without any issues.

I think it's in your phone only. When you get a notification saying install software. I don't know for sure but tou can try that, if it doesn't, I'll give you the drivers

[SOLVED] Unbrick c5303 possible?

Hey Folks,
Yesterday I came accross a new firmware for my C5303 (Stock) Rom. Problem was, something went fishy on my computer and the upgrade process went south midways.
Probelm being: I have neither rooted, nor unlocked the bootloader.
Is there a way to unbrick? Unfortunatelly I have learned, that appart from other SONY devices, the SP is not so peachy when it comes to custom roms.
Current state:
The device is not recogniced by the flash tool of Sony, or the suite.
Could someone point fingers where to look for a solution?

You will have to flash an FTF file using "flashtool".
A search on this forum will surely point you in the right direction.
There are already plenty of guides.
Good luck!

The device is not recogniced by the flash tool of Sony, or the suite.
Could someone point fingers where to look for a solution?

I bricked mine yesterday at 11 pm,couldnt sleep right cause of the panic. xD
My C5303 has a LOCKED BOOTLOADER too,and I was stuck at the SONY logo.
I downloaded Flashtool.
I installed Flashtool.
This procedure is neccessary in order to install fastboot/flashmode/adb drivers.If you already did it,skip it.
If ur on windows 8,move ur mouse coursor to top right of the screen,a toolbar will appear.
Then click SETTINGS.Then click CHANGE PC SETTINGS.When it opens,select UPDATE & RECOVERY.Select RECOVERY.Select ADVANCED STARTUP.When it reboots,you will see a blue background and an option,i think it is TROUBLESHOOT,anyways,look for DISABLE DRIVER SIGNATURE VERIFICATION.But as I remember,i was put with a choice of selecting a number,and i pressed 7-DISABLE DRIVER VERIFICATION.
The PC will boot like nothing is changed,but now u can install the drivers.
Go to Flashtool/drivers and open the installation program
Select "Flashmode drivers","fastboot drivers" and "common drivers for Viskan board(these are the ADB drivers ONLY for the Xperia SP)"
The PC will ask you to allow the driver installation,allow all of them.Reboot ur pc again,and connect ur phone in flashmode for the pc to link the flashmode drivers to ur Xperia SP,then u can begin.
Download this firmware FROM THIS LINK
http://www.xperiadownload.cz/phocadownload/userupload/download/2013/SP/C5303_12.1.A.1.205_CE.rar
extract the ftf file with any rar program,then move the .ftf file to the FIRMWARE folder in the directory where flashtool is installed,mine is C:/Flashtool.move the .ftf file into (DRIVE):/Flashtool/firmwares
Open Flashtool,select Flash with Flashmode,wait for the program to say that u can connect ur xperia sp with the PC.To enter Flashmode hold the Volume DOWN button while connecting the phone to the PC.
I reccommend using the SONY cable,as i have a feeling it is the best one for these things.
Let Fashtool flash everything,do not touch the device at all until the Flashtool allows you to do so.

Thanks for all the answers so far...
I figured, taht in the flashtool the firmware for the device is not listet, although it is in the respektive directory. am I blind, or am I missing something?
It however does offer a X10 installation, what ever that is, when it is at home

Look for an FTF file on this forum.
Make sure you download and flash the correct one!

It is recognised by the flash tool and therefore, I believe it works well... I'll keep you folks postet... FINGERS CROSSED

Okay folks, you can uncross your fingers... Thanks to all of you, the call is back to life!
