Below link is my rooted system image (img format).

www(dot)multiupload(dot)com/AF56GU8XDT


Just use below command to flash it: (of couse you must unlock you phone first)

fastboot.exe -i 0x0fce flash system rootsys.img

Below link is the guide how to re-lock Xperia mini:

www(dot)theandroidsoul(dot)com/guide-how-to-relock-boot-loader-on-xperia-arc


it worked for my xperia mini st15i,I already tried it.but DRM (Digital rights management) and trackid can't work.

Are the rooting instructins (and unlocking bootloader) ONLY for Mini Pro or will they also work on Mini?

Thanks for the quick reponse but I am even more confused now. I thought in order to flash the fimware I had to be on build 4.0.A.2.368.
Is that not the case?
Thanks

if u are already on that FW then u DO NOT NEED TO FLASH FTF...

u need to flash FTF ONLY IF u are on OLD FW...

there are two seperate threads for these two devices...

the boot.img is the only this which is different...

I think i may have casued too much confusion.
Let me start at the begining.

I am on build 4.0.A.2.364.

According to the posts at start, if I want to use the ROM then I need to be on 4.0.A.2.368.

Questions;
1) Do I need to be on 4.0.A.2.368 to use the aforementioned ROM?
2) If yes then how do I get to 4.0.A.2.368 as the first article says I need to be on 4.0.A.2.368 to use the firmware. If this is the firmware that gets me to 4.0.A.2.368 then Im going round and round in circle - e.g. im not on 4.0.A.2.368 but cant get to it as I need to be on it in order to flash the firmware

Hope that makes sense

ok somethign to clear up confusion:

1) this is not a ROM
2) this is a Original (untouched) SE Firmware (FW)
3) this thread gives u 2 options
- (a) update/flash to newest FW (no requirements other than FLASHTOOL)
- (b) if u want u can root this FW (using boot.img provided)

to get to latest FW u need to flash the FTF (link in 1st post) using FLASHTOOL...

I used Flashtools 3.0 to flash the firmware for STi15 (Mini). Went through the process and at end states I need to turn on phone, activate debug mode and unknown sources. So far so good. Once this is done Flastool shows choice of two devices that mine should (Mini Pro (SK17) and X10 ) It did not show Xperia Mini.

I checked the devices folder and found one for Sk17i and one X10. There is no folder for STi15 (Xperia Mini).
When I checked my build number it says 4.0.a.2.368 (was previously 364).
Does this mean flashtool has worked?
Can I now continue with Root process?

Thanks

Edited as follows:
Flashtools wont root it as it doesnt recognise the device. I believe I need to create a folder for STi15 and put appropriate files in there. What are these files? Do I need to edit any of them?

Superoneclick got to 'Rooting device Step#5' and just sat there for about 15 minutes before I disconnected it.

Edited again:

After disconnecting it went to step 6 and 7. I reconnected device and it said Busybox not installed - install it?
I selected Yes.
Completed and said device rooted.
I rebooted, ran Superuser, installed Root Explorer, Ran Root explorer, got the prompt from superuser for permissions. Granted permissions and it seems I have root access :)

Hi everybody!
Is there a way to find out if i have an unlocked bootloader or not?
I have the right firmware version in my Mini and i really want to root it!!
Can you easily reverse it to stock condition for guaranty reasons?
Thanks!!

Root without unlocked bootloader...

So, as the topic says.. Is there no currently known "exploit" for getting root without unlocking the bootloader?

Well, that sucks and i guess i have to seach for a solution for this. If i have read the info on different sites correct, then i trash my DRM management if i unlock the bootloader or?

thanks for the quick response. Much appreciated.
How do I remove the notification from the task bar. I have tried to go in to 'About phone/Updates' but there is no option in that section to stop notification either
thanks

    What about .377 fw ?
    Does the procedure and your kernel work or do we have to stay on an "outdated" fw ? :cool:

    i was informed that .377 FW doesnt have many changes... also the kernel sources for that FW are not available...

    one of the user/tester told me that the insecure kernel which i have posted here (.368) also works w/o any issue on .377

    so u can still use that insecure kernel
