Xperia Active Root nach 4.0.4 Update weg; was ging falsch

[mvaro2002]

Hallo Community,

habe gestern das Tutorial für Xperia Root befolgt aber irgendwas ging schief:

1.) Flashtool 0.6.9.1 installiert
2.) Alte Firmware raufgespielt (Xperia Active (ST17i)_4.0.2.A.0.42_CE.ftf)
3.) Update über Playstore gemacht aber beim letzten Update auf Version (4.1.B.0.587) hab ich das Handy im Auslieferungszustand vorgefunden.

Hab mich durch die vielen Posts geklickt war aber etwas skeptisch da viele doch schon ca. 2 Jahre alt. Bitte um Hilfe, bin hier sehr unerfahren.

THX

Heute die "andere" klassische Variante ausprobiert, aber irgendwie ging da was auch schief, telefon ist up to date aber eben alles beim alten. Hat wer nen screenshot vom flash tool was da wie angeklickt werden muss? Das fehlt hier nämlich:

We cannot root 4.1.B.0.587 directly, so to root it we first flash 4.1.A.0.562 kernel, run the rooting toolkit and in the end flash 4.1.B.0.587 kernel.
Few devices don't have their own 4.1.A.0.562 kernel, so we need to flash the 4.1.A.0.562 kernel of other devices just to root. However all devices have 4.1.B.0.587 kernel.

Follow all the steps.
Go to settings > Security > Mark "Unknown sources"
Settings > Developer options > Mark USB debugging
Settings > Xperia > connectivity > USB connection mode > select MSC mode

Download Flashtool
Windows Users > Flashtool
Linux Users > Flashtool ( From previous release tab, download 0.9.0.0 version)

After installing flashtool, reboot your PC.
1 ) Download the respective 4.1.A.0.562 kernel to flash
Arc and Arc S - Kernel
Ray - Kernel
Neo/Neo V - Kernel
LwW, Mini - Kernel
Active - Kernel
Neo L - Kernel
All other users - Kernel or even try the kernels for Arc S and Ray
2) Go to C:/ Drive > flashtool > firmwares > delete everything present and put the downloaded kernel
3) Run Flashtool > click on the flashing icon ( left side below "file" option)
Select flashmode > ok
Setup should be like this > select OK


Flashtool Setup Screenshot
Follow the steps, connect your mobile and flash. Note: on devices with touch navigation keys, hold volume down key instead of back button while connecting your device.

Flashtool may show error after flashing kernel, no worries. Even your build number and android version won't change. Everything would remain same so please don't visit phone's settings to check anything
4) After flashing restart your device, It may not start completely, may remain at Sony logo or with blank/black screen.
Whatever the status is, just restart your device and proceed with the rooting >
Download Rooitng toolkit > 1 / 2 / 3 / 4 and extract it.
( Make sure you close flashtool before running the rooting toolkit )
Now connect your mobile to PC ( Mobile should be ON) and wait for 2 minutes. Then run the rooting toolkit. When it says all done, close it. disconnect your phone and switch it off ( By pressing power button/ or by taking out the battery and reinserting it).
5) Download Kerenls, If you are on 4.1.b.0.431 rom then download the respective kernel, same goes for 4.1.B.0.587
For Neo L > Download the kernel version on which your phone is running 4.1.B.0.626 or 4.1.B.0.631
Xperia
4.1.B.0.431
4.1.B.0.587
Arc S Kernel Kernel
Arc Kernel Kernel
Ray Kernel Kernel
Neo Kernel Kernel
Neo V Kernel Kernel
Mini Kernel Kernel
Pro Kernel Kernel
Live with walkman Kernel Kernel
Active Kernel Kernel
Mini Pro Kernel Kernel
Now flash the kernel ( same procedure as step 2 and 3 above )
Your mobile should now b rooted (See if any Superuser app has been installed on your phone ) and working fine again.
