[Sony Xperia S, Acro S, Ion] ricstc:
For Acro S LT26w short GUIDE & Confirmation of ROOT on .211

Hi

Of course priceless THANKS (and I will buy a beer on paypal after this) to DoomLord.

I own both Xperia Acro S and Xperia Go and wish to post my summary of confirmation and a short GUIDE to show (and hopefully HELP) those that own these model of phones that the STEPS work and that DooMLoRD's Easy Rooting Toolkit (v16) {perf_event exploit}[20130706] works.

How I upgraded Acro S from ICS 4.0.4 6.1.A.2.45 to Jelly Bean (JB) 4.1.2 6.2.B.0.200 then to .211 (Note: you can upgrade STRAIGHT to ,211 but in this short GUIDE of mine, I show you the .200 then onwards to .211 flow)

Use SUS to download the latest official ROM. LT26w (6.2.B.0.200) - if you get .211 great! The steps are the same anyway.

1. after you have had your stock / official FW download completed - check that the phone is now on the new FW - but that you have NO ROOT

2. Then download DL's exploit from here http://xdaforums.com/showthread.php?t=2327472 DooMLoRD Easy Rooting Toolkit (v16) {perf_event exploit}[20130706]

3. Extracting the files to any folder

4. after your extraction you would only need to launch an Administrative Right CMD prompt

5. Then run the BAT file

C:\DLv16>dir

07/05/2013 11:49 PM 2,128 runme_win.bat

C:\DLv16>runme_win.bat

Note: follow the on screen instructions given by DoomLord in his Batch file below

especially the Before u begin part. Redo the steps even if it is done or shown to be ticked in the phone. Redo the steps and also reconnect the phone via USB and hear the plug-n-play-"tu-dut" sound to confirm that your phone is USB connected. if not you will receive errors. ALSO, make sure that Flashtool.exe (if you have this opened and running) is NOT running, else you will have errors like this here

*** If Flashtool not exited or closed you will get this

--- WAITING FOR DEVICE

adb server is out of date. killing...

ADB server didn't ACK

* failed to start daemon *

error:

--- creating temporary directory

adb server is out of date. killing...

(and it LOOPS here with further errors)

6. When you run DoomLord's runme_win.bat file you get this below:

ALL DONE!!!

Press any key to continue . . .

8. After some waiting, you phone's home screen is shown - your DATA and SETTINGS are NOT LOST. Check that all is OKAY and that you have ROOT rights.

If, like me, you want to proceed with downloading the .211 FTF and then FLASHTOOL-ing it, then follow the steps below. Else you are DONE.

To FLASHTOOL .211 ftf Firmware for Acro S

This will require the use of the latest flashtool so read this too

http://xdaforums.com/showthread.php?p=42659596#post42659596

In summary, YOU ONLY NEED THE KERNEL.SIN & SYSTEM.SIN to be FLASHED

Note: Get and use the latest Flashtool here http://androxyde.github.io/ flashtool-0.9.11.0-windows

How to use Flashtool? (that's a standalone topic by itself - so I may post the Step by Step later if asked) or someone please paste a link to it for all to follow.)

Anyway, Remember to uncheck every Checkbox

EXCEPT

the System and Kernel Checkbox

So If you follow the specific instructions, you will get to see loader.sin, system.sin and kernel.sin ONLY

After this check that your phone is on FW .211 but NOT ROOTED.

then run DoomLord's ERKit v16 batch file again (***AGAIN, MAKE SURE Flashtool is EXITed) and see it get ROOTED!

DONE.

If any of the steps posted in this sharing is unclear, please ASK but don't forget to say thanks to DoomLord and the others that have brought this for you.

I am a mere MESSENGER.

Good luck!
