As mentioned above I did the procedure,It work fine for me I downgraded. I found that my ray was fast with gingerbread rom.
I do not need to unlock bootloader as it was OEM unlocked. I would like to install custom rom from XDA. should i take back up of origional kernel? if yes how?
and if i install custom rom and reverted it back to 2.3.4 or ICS with its origional kernel, is it possible still i can use pc companion to update it?

I just want to confirm if I should root my Xperia Mini pro SK17i first before downgrading it from ICS .587 to Gingerbread via flashtool? and is your GB firmwares generic? Can I use it regardless of the SI number I have?
