[Q] Japan Arc no unlock key screen

gagafafa · Apr 12, 2011

I had bought a Japan ARC [SO-01], unfortunately, I bought it b4 1 April, so i cannot get unlocked by docomo and also I'm not in japan now...

I think the unlock code from some provider also work but the problem is that, my phone will not prompt any unlock key insert screen, please help :"(

All Docomo phones sold before and after April 1st still come carrier-locked. The only difference is that starting April 1st, you can now take your handset into Docomo, pay ￥3150, and get your phone unlocked -- even if you bought your phone before April 1st.

You will have to go into a Docomo store, however. If your phone is still carrier-locked (to Docomo), your best shot is to find someone in Japan who can do it for you. Perhaps you can contact the seller and arrange the unlock for some fee.

thanks for confirming this info , i have ordered a docomo xperia arc so that i can use it in the usa , but people have been doubting that it can be unlocked because it was released on March 24th.

the Lt15a(America version) and the Docomo SO-01c are hte same and that is why i ordered from japan

Although they say "They can do" but actually they cannot do, because nobody can find entry screen for unlock code. I bought UNLOCK code from them but cannot do this.

alsaqr · Apr 13, 2011

i have contacted this unlock code provider

they have replied sayin it is possible
in the middle of the page there is a way to show you how you get the code screen and hidden menu

this was their reply(my original message is at the bottom

Can you unlock the japanese xperia arc ?

its the Docomo SO-01c

morita0107 · Apr 15, 2011

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 can return it to DoCoMo firmware. You just need somebody to update their DoCoMo arc and send you the firmware files.

If you would like to reveal how to do so, I could be of assistance.

Sure, the box says exactly this: "GSM/GPRS/EDGE 850/900/1800/1900 UMTS/HSPA Bands 1/2/5/6" The UMTS/HSPA bands are 2100/1900/850/800.

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.

Arg. Too bad. Thanks for the quick reply.

I think that any japan arc, could be flashed anywhere with an european version software (ie: unlocked LT15i flash rom). The phone will result with the european firmware, but it will support american and japanese networks.

I did that with my C905, its model is "C905a", but I flashed it whit the C905i firmware because of different spanish text from Europa. I use 3G in chile with no prob.

SO, can't this be done to a Japanese Xperia arc?
