Re: {GUIDE} How to Root Xperia™ Smartphones

Install the drivers mate

Go to C:/ > flashtool > drivers > flashmode drivers > install

If that doesn't work then use this version of flashtool

Re: {GUIDE} How to Root Xperia™ Smartphones

Hi Nabeel,

I had relocked the bootloader and it worked ... updated to 4.0.4...

Before I go ahead, I want to clear something.. Earlier user soumikray posted:

"

Thnx again for the guide. Last time I rooted GB with ur help. This time I rooted ICS .587 with ur help. Just 1 thing I wud like to mention here, at the xda page of doomlord there is a list as follows:

Before u begin: 

  1. make sure u have installed adb drivers for ur device
  2. enable "USB DEBUGGING" - from (Menu\Settings\Developer Options\Development)
  3. enable "UNKNOWN SOURCES" - from (Menu\Settings\Security)
  4. [OPTIONAL] increase screen timeout to 10 minutes
  5. connect USB cable to PHONE and then connect to PC
  6. skip "PC Companion Software" prompt on device

"In between point 4 & 5, there should be a mention that u need to connect the usb cable while pressing the back button of your phone."

A lot of people who are not so experienced, they just connect the phone normally & the rooting toolkit doesnt work. Thought it wud help people so I mentioned it here.

"

Do I need to hold the back button while connecting the phone for rooting ... it didn't work? The rooting procedure has failed yet again. I think I'm missing something but dunno what. the steps I have taken:

1) Unlocked bootloader through Android SDK (again.....)

2) Downloaded flashtool 0.9 and installed the drivers(windows 8 procedure).

3) Flashed the device in flashmode (volume down button for Ray) using your link: http://www.4shared.com/file/QSM6uqPU/ST18i_41A0562_kernel.html

4) rooted through dommlord v4 ,,,, this step failed yet again...!!!!

Did I miss a step ... ?

Re: {GUIDE} How to Root Xperia™ Smartphones

creptil Nopes , you don't have to hold any button while connecting.

I've updated few lines in the guide now.

OMG Anguished Face , creptil Why why why aren't you following the steps correctly mate ?

You've to use the toolkit for ICS. v4 is for GB, V1 is for ICS, see the first page again, in the step 4 download link has been given.

Please follow the instructions carefully Slightly frowning Face

LeoOrta Link updated Slightly smiling Face
