if you want to try it,first thing you need to have flashtool.

You can download Flashtool from this thread

You need original file from SEUS in order to flash the original kernel (FW.62) back to you phone.

 

[puppet13th]

Kernel only Flashtool files :

- Xperia Arc LT15i_4.0.2.A.0.42_kernel only.ftf

- Xperia Neo MT15i_4.0.2.A.0.42_kernel only.ftf

- Xperia Mini Pro SK17i_4.0.2.A.0.58_kernel only.ftf

- Xperia Mini ST15i_4.0.2.A.0.42_kernel only.ftf

- Xperia Active ST17i_4.0.2.A.0.42_kernel only.ftf

- Live With Walkman WT19i_4.0.2.A.0.42_kernel only.ftf

You will need loader.sin to create bundle for flashing original .62 kernel

i will working on a guide later :-D

 

[zurazuzi]

downgrate to 42 Fw with wotanserver.com its best way

 

[puppet13th]

updated 1st post with completed guide. :-D

To get ROOT working on .62 FW,we need to flash older kernel in order zergrush exploit to work on the ROM.

You need Flashtool found in this thread

download following flash file according to your device.

- Xperia Arc LT15i_4.0.2.A.0.42_kernel only.ftf
- Xperia Neo MT15i_4.0.2.A.0.42_kernel only.ftf
- Xperia Mini Pro SK17i_4.0.2.A.0.58_kernel only.ftf
- Xperia Mini ST15i_4.0.2.A.0.42_kernel only.ftf
- Xperia Active ST17i_4.0.2.A.0.42_kernel only.ftf
- Live With Walkman WT19i_4.0.2.A.0.42_kernel only.ftf

put downloaded file to flashtool\firmware folder
flash your device using flashtool using downloaded file.

after that try to root your device with zergrush method
this can be achive using flashtool as well

after your phone was ROOTED,you need to flash .62 back to your device.
you need firmware from SEUS can be found on
SEUS\DB\13740270\blob_fs

copy any file named FILE_?????????
there should be 3 files like that,if you found serveral files like that copy the newest files
put it on one folder
download loader.sin and put it on that folder

create new bundle :
1. open flashtool
2. advanced -> decrypt files
3. point the folder contain SEUS FW + loader.sin
4. after file decrypted it will show bundle creation
5. just select kernel.sin and loader.sin
6. fill device , version and branding
7. flash your device with the newly created file

to test if your have correctly flash .62 kernel,try to run zergrush exploit on your device

dont understand. it's need to unlocked bootloader?

root 62

I used Flashtool-0.6.6 and in it the "Flash FastBoot Mode"> "Select a HotBoot kernel" in which kernel to boot on your PC (I used it from FXP 103). after the start I went into recovery and flash file RootXperia.zip + Recovery-Addon.zip. then restart and mini default kernel + root + recovery

for files and Recovery RootXperia.zip-dik Addon.zip belongs to people from XDA.

I'm sorry for the google translator English better

 

[puppet13th]

dont understand. it's need to unlocked bootloader?

if zergrush exploit working on erlier kernel,it should give us a way to gain root access.

We don't need to unlock bootloader in order to flash kernel files that originally come from SEUS.

What do you actually mean with 'you need firmware from SEUS'?
I have been trying to figure out what SEUS is and where I can download it.

after your phone was ROOTED,you need to flash .62 back to your device.
you need firmware from SEUS can be found on
SEUS\DB\13740270\blob_fs

SEUS = Sony Ericsson Update Service

that is location example
usualy SEUS installed on "c:\program files\sony ericsson\update service"

Hello, I have flashed my phone back to the .58 kernel, but I still can't root. In the service menu it now says:
Phone software version: 1244-7088_4.0.2.A.0.58, generic - user
but file system version says: world-i_4.0.2.A.0.62
In the "about phone" menu, it also says build .62.
The deletable pre-installed apps such as Wise Pilot and UEFA came back and PCC tells me that is new firmware available again (.62)

What am I doing wrong?

Same thing here. I don't even have a update service folder. Mine says update engine. Still can't find SEUS\DB\13740270\blob_fs.
And you say SEUS is Sony Ericsson Update Service, is that the same as Sony Ericsson PC Companion?

 

[sirmarcelot]

im not sure about this step:
6. fill device , version and branding

is there some way i can copy the exact same values from my current rom? im not sure what to enter here. i use a .62 claro operator sk17a

 

[sirmarcelot]

just tried this on my sk17a and i couldnt flash the kernel - nothing happens, and it says that i do not have debug on - which is not true..

which flash mode am i supposed to use? i used 'flashmode', not the 'fast boot one' - should i use it?

maybe i need a different kernel to do it? anyone was able to

 

[puppet13th]

It's look like zergrush exploit patch was stored at /system partition,so if we just flash older kernel will not revert the zergrush exploit patch.if we want to use. 62 firmware we need .62 update.zip ROM that contain su binary stored on /system partition.
