As today we need either one of these in order to archieve the final goal (which as i mentioned, is to modify/rewrite/change the baseband):

    Available option:

    Option A) We need to find a hole in the bootloader 4.6 that allow us to reach the baseband or

    Option B) We find the correct secpack for the baseband 04.02.13_G, in order to erase it/change it/modify it.

    My 2 cents.
    I think I really have some problems in explaining myself..

    We are in fact telling the same thing are you aware of that? What I was trying to tell by saying "the problem is not the baseband" is the following:

    Assume that you have an OOTB 1.1.1 phone, OK? If you upgrade it to 1.1.2, your baseband also upgrades to 04.02.13_G, all right? And you can downgrade again to 1.1.1 and your baseband still remains as 04.02.13_G, do we agree on that?

    Then using aynSIM 1.2u, you can unlock this 04.02.13_G baseband, am I wrong?

    BUT, the point is that, you can do all these things only if you have the bootloader 3.9! So as all we know, the OOTB 1.1.2 phones also have the 04.02.13_G baseband which is unlockable by anySIM 1.2u, as I told above but we cannot unlock these OOTB 1.1.2 phones... WHY? Because the bootloader is no longer 3.9! It is 4.6!

    So what we deduce here is that, the problem is NOT with the BASEBAND of the OOTB 1.1.2 phones, it IS with the bootloader of them, which is 4.6! If the bootloader did not make this signature check - which has not been broken yet - anySIM 1.2u would easily "reach" that 04.02.13_G baseband and unlock it as it did for upgraded 1.1.2 phones.

    QED!

    Absolutely 100% correct.

    Asked a couple of times, but didn't get a clear answer!

    there is now easy way to do that, that is the reason, until this moment the only way to "downgrade" de Bootloader is by harware....desolder the chip and reprograming the old bootloader and solder again in the comm board (hard stuff to do)

    Actually there is no software downgrade bootloader option
