So you did the inevitable... you got a phone that's bricked.. fear not.. this happens to all of us.. consider it a "right of passage" when it comes to dealing with custom ROM's :)

Here at xda, help is never too far away :D (I was there once too)
I've tried to get you back to functioning latest Local 2.1 with recovery (xrecovery)

0) You'll lose all data with this method....
come to terms with that... not stuff on the sd card but data of your phone, sms'es, contacts, applications etc


1) Turn off your phone
Pull the battery and reinsert it if you have to...

2) Install Flashtool
go here and downlad flashtool
Install on your windows pc
Thank Androxyde and Bin4ry for this kickass tool :D

3) Download and flash stock 2.1
Go to this thread and download a 2.1 rom in your language of choice (Dont worry that it's not your local ROM)

4) Flash this rom using Flashtool
In the first link there is a how-to. follow it and flash the downloaded ROM from step 3

Once you have 2.1 on your phone,

5) Enable USB Debugging and Root
Use flashtool and root your phone using the simple button "Root" (I know!! what an awesome tool right!!?? :D)
Once rooted, disconnect the phone.

6) Get yourself a root file manager
Download a file manager capable of root access such as root explorer or solid explorer.

7) Access and edit the build.prop file
Open the file manager. U should get a superuser prompt to allow root access. Touch "Allow". Go to /system and mount the system as RW. there's a file there called build.prop. open it in a text editor. Find all instances of a number that looks like this 1238-9045 (this is my build number, yours will not be the same). Edit this number(all 3 instances) to look like your build number (Found on original box or behind the battery). Save the file and exit

8) Update via SEUS OR PC companion
Now connect your phone back. PC companion or SEUS will tell you there is a new update available. follow the instructions and you'll be running the latest 2.1 for your region and variant of the mini pro

9) [optional] Root and recovery
The new firmware installed by SEUS/PC companion is not rooted. If you need it, root again (same way as in step 5). once rooted, click "Ask root perms" on flashtool. Once root access is confirmed, install xrecovery from the menu.

Hope that helped!

Enjoy :)

Edit: if you get an error while opening flashtool saying "JVM could not be started because heap size bla bla bla..." Please try on another pc and maybe reinstall windows on urs :D

I have bricked xperia mini x10, and it's failing to boot. Debugging is turned off, so flashboot can't recognize it.

16/010/2012 19:10:31 - INFO - Device connected with USB debugging off
16/010/2012 19:10:31 - INFO - For 2011 devices line, be sure you are not in MTP mode

Can someone help?

Repair it with SEUS or PC Companion.
Step A: leave your phone disconnected from your PC
Step B: Run SEUS/PC Companion, and select update
Step C: It doesn't recognise your phone because it's disconnected and give you a repair option
Step D: Select it, choose your model, it will download the firmware
Step Ea: You get a popup, Press the back-button on your phone while it's off and plug in the USB-Cable
Step Eb: If you can't turn off your phone, plug in the USB-cable and press home- and power-buttons at the same time, it will do a hard reboot and enter flashmode.
Step F: Wait till it's done...

everything past item 3 is pretty hard since we can't acces anything on phone(that's bricking a phone right) to enable usb debugging.
Good tutorial though for those who installed a custom rom and they want to revert to original plus root acces.
Any ideea how to force seus or flash to force flash?

You don't need usb-debugging in order to flash your phone.

Not too sure of the greek firmware file bro.. can you put the link of the forum where you got it from? are you sure it is a stock firmware?

cant flash using SEUS...its saying i have latest version but in reality the phone is already bricked by me and not having the original stock firmware... now it just keeps restart with sony erricson logo and turns off again and bootloop...cant root, cant flash... heard that there is some special modified usb that will make the bootloader enter download mode so that we can flash fresh firmware inside it?

You can always flash... post your model and if your bootloader is locked or unlocked ( since you're on SE kernel logo, i assume it's locked), and i can provide you with stock firmware (E10i or U20i) to flash with flashtool.

hi, i am u20i model...i accidentally locked the bootloader while having nna kernel i think, because flashing customised rom and kernel, my phone will enter bootloop, thats why i pressed Restore inside s1tool.exe, which got my bootloader locked....

and now that my bootloader is locked, and i cant root my phone without turning it on( the phone bricked cant turn on anymore) i cant unlock my bootloader to flash new kernels into it... please do provide stock firmware and rom for me... i can only flash stock kernel, but not the rom... after i flashed the stock u20i kernel, i dont know how to flash the original rom into my phone, since now my phone, didnt have the CWM or XRecover anymore, which can browse my SD card, and install the rom from .zip files....

flashing stock kernel no problem but did not know how to flash the stock rom

Download this, It's the complete SE 2.1 Firmware (Kernel and ROM), flashable with flashtool.

(It's about 213.5MB, although the site may display it's less in your download dialog, but it will keep downloading till it's all there)
