After unlocking Arc, I'm now available to use SoftBank (in Japan), O2 and Vodafone (in UK). Of course this can use docomo SP-mode.
Now I'm very confortable with no stress. :)

Thanks so much!
I could do successfully and now mine was returned to the version of Docomo.

As FYI, after flashing it, have updated as Repair mode on SEUS.
Absolutely this is NOW Docomo edition.

Great job!

this is a sony ericcson xperia x12 arc SO-01C of NTT docomo

this is a sony ericcson xperia x12 arc SO-01C of NTT docomo (same models LT15a , LT15i )
first of all you have to update ROM to LT15i
you can update rom by WotanClient software on wotanserver.com it is free now
then insert SIM card other than docomo
With a Non accepted simcard start up the phone. When the screen says "SIM network unlock PIN"
please don't enter wrong code because you have only 10 attempt then it would be hard locked
*#06# get your phone IMEI numder
unlock code was purchased on cellunlocker.net (received in about 6 days)
enter SIM Unlock code
well done

    Basically Docomo says this model cannot be UNLOCKED and this has to keep specified ROM.

    But finally I could UNLOCK by flashing global ROM and after completing ROM flashing, unlock screen appeared. Therefore I could enter unlock code successfully!

    But the key thing is that this cannot be returned to original ROM which is provided from Docomo, so now this is UK or Chinese (HKG) version (LT-15i).
    And slightly Japanese font is different from original font style, probably this is Chinese KANJI, I guess.

    You need someone with DoCoMo firmware to update their phone. If they then pack the 'db' folder from SEUS and upload it, I will be able to make an .ftf file for flashtool.

    Hi,

    Usually I am in Japan but this month I have to stay in France. If I get a Xperia arc european version here and then take it to Japan with me.
    Will it be possible to use it in Japan? Does the european version support the japanese network?
    Will it be possible to flash the docomo firmware to use sp mode?

    Thanks

    No, you can not get the European version, the LT15i, for use on DoCoMo. I'm unsure of Softbank.
