    To try and help, I visited the WiKi site for a List of LTE networks in Italy and Japan.
    Now I am not sure how accurate this information is, but posted below.

    My approach to this would be to look at what is working in Italy and see if there is a parallel service in Japan.

    This information shows:
    Italy Vodafone operates on 800 and 1800 frequency or band 3 & 20.

    Japan only has one network that works on band 3 and none on band 20.
    In Japan the most common Bands are 1 & 28

    Looking at European LTE networks there is only 1 that operates on Band 28 and 0 on band 1.
    Therefore it is highly unlikely that you will find European firmware to support LTE in Japan on your European N9005.

    Thanks! I appreciate all your work to help me solve the problem!

    Actually it was I the person who updated the Wikipedia records for Vodafone and Softbank.
    :-)

    So I knew the basebands and frequencies of the operators. What I don't know is which MPN I need to flash and where to find it. These are the frequencies/bands which I need:
    1, 3, 8 and 20

    I really did appreciate your time and I wish I could show my gratitude!

    Found this at Sammobile (of all places)
    Says that the i9005 supports the LTE 1,3,5,7,20 bands.

    http://www.sammobile.com/2013/09/01/...certification/

    This is the hardware set up of your modem and cannot be changed.

    @ greenman,

    Again, thanks! At least you have clarified to me that each MPN has its own separate radios and that, therefore, I need to find the right MPN firmware to fix my problem.

    But during my 3+ weeks of research I found many official webisetes that claim differently. This is only one of them: http://www.samsung.com/hk_en/consume...SM-N9005ZKATGY (BTW, here they mention yet another MPN). But also Samsung UK, Italy, France etc... they all claim that the N9005 for those regions can work on the LTE bands which I need (1, 3, 8 and 20).

    My problem is to find the right MPN code name firmware and then find where I can download it from to flash it into my device to setup the right radios which will work on those 4 bands.

    I found some links, but I'm not sure that these are the right ones...: http://www.samsung.com/uk/function/s...ords=N9005+MPN

    The link to the Hong Kong Samsung site shows all LTE bands that you want.
    However if you go to a European Samsung site, you will see the LTE bands are qualified with the words 'depending on region'.

    So, where you purchase the phone is vital to the LTE service supported.

    An S3 bought in Hong Kong would support bands 1,3,8 & 20.
    An S3 bought in Europe will not, and to my understanding cannot be changed - but it may be worth trying an Hong Kong firmware.

    By the way, it is the firmware that has the modem information, the MPN will tell you which modem the phone has within the same model.

    To my understandings firmware/modems can be changed. The problem is identifying the right one and then finding where to download it from.

    This information is important but I don't know which MPN refers to which modem/firmware...

    That would be a first step: finding the right firmware/modem (region) for my frequencies and then finding which MPN it refers to or includes it. Your suggestion might be right: the HK firmware/modem could work on all my frequencies/bands... how can I verify it?

    Anyway... if at least I could get that first step fixed, then I could start asking around in forums where I could find that firmware/modem it and how to flash it...

    This is my understanding.
    The modem is 'hardware set' to respond to a range of frequencies.
    How these frequencies are accessed and the connection made will be a software programme.
    So this part can be changed by a reprogramming of the firmware.
    But, you cannot change the frequency itself.

    Having just read this XDA link on the Hong Kong N9005, the problems in installing EUR firmware appears to be due to an incompatibility in modems.

    http://forum.xda-developers.com/show....php?t=2486605

    I believe there is no answer to your problem, other than purchase a phone with a modem having the frequency support you need.

    The European N9005 does not have this, and cannot be modified.

    It is Band 8, that is the problem, and I do not believe a resolvable one in a European N9005.

    Yes, I read that whole thread, plus the official kk thread. It took me 5 hours and fifteen minutes!

    Only by reading those posts, not from direct knowledge, I came to the opposite deduction: a modem/radio can be flashed.

    But I must find the appropriate scs, with the appropriate frequencies instructions. Once more, I'm back to the original quest: the right MPN and where to download it from...

    Of course, there is the problem of how to flash such radio/modem, once I find it. I have absolutely no idea of the technicalities involved.

    After all.. if you think about it, that's exactly what some ROMs do: they carry better radios/modems.

    I have the hardware, now I need the firmware.
