[Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A] Abhinav1997:
U can use the fxp cm 10 151 which is quite stable on the extended kernel(cm10) by m66b till now....only some minor bugs but it is a good choice...

Here are steps to do it: (it's better if you are on extended kernel and rom but it's not necessary since I flashed on kernel panic 1.25 and delicious rom 2.1)

1.Download the latest fxp rom from here and place it in the sdcard.

Optional

: Download gapps from here and place this also in sdcard.

2.Now turn off the phone.

3.Now download the extended kernel from here.

3.Now extract the kernel and move boot.img to a known place on computer.

4.Now hold vol.up button and connect the phone to pc.(Blue led should light up)

5.Now you are in fastboot mode. Now launch flashtool.

6.Click on the flashing icon and select fastboot mode.

7.Now click on select kernel to flash and select the boot.img you extracted earlier.

8.If no error occur then you are successful. Now disconnect your phone from computer and turn it on.

9.Now the logo must appear. As soon as it gets brighter press the vol.down button.(I keep it pressing till I go in recovery)

10.Now wipe data/factory reset and also wipe cache.

11.Now go to install zip from sdcard->choose zip from sdcard->select the rom to flash.

Optional

:Flash the gapps in the same way.

12.Now turn on the phone.

If you see the screen you're successful....Enjoy jb

If you get status 7 error do the following steps...

If you failed at first time(me too and got the same error), its better to start from the starting...

1.Download the rom again as the zip might be corrupt.

2.Extract the zip and then go to: META-INF->com->google->android

3.Download the updater-script from here

4.Replace the updater-script from the one I gave.

6.Copy the boot.img persent in the zip to any folder you want.

5.Now right click the rom folder and archive/compress it as zip.

6.Place it in your sdcard.

Optional

: Download gapps from here(Find the suitable one) and place it in sdcard too.

7.Turn off your phone.

8.Download flashtool from here.

9.Now install flashtool in C: Drive(Recommended).

10.Now go to Local Disc (C:)->Flashtool->Drivers and install the file given there and choose all the drivers.

11.Hold vol-up key and connect the mobile to computer(blue-led may light up).

12.Launch flashtool and click on the flash icon and select fastboot.

13.Now click select kernel to flash and select the boot.img you kept the folder of your choice.

14.After the flashing is finished check the flashtool if there is any error.

15.If not continue....

16.Now turn the phone on.

17.As soon as the screen gets brighter or any led glows start pressing vol-down button.

18.Now you might be in recovery mode. Do a wipe data/factory reset

19.Now choose install zip from sdcard->choose zip from sdcard and select the rom.

Optional

: Do the same for gapps.

20.Now reboot the phone.
