Allow flashing global firmwares on Docomo model Xperias about newflasher HOT 5 CLOSED

Product devices e.g. SO-05K , XX, YY, ZZ ...etc have their own signing procedure and you can't flash firmware in any way, e.g. you can't flash H8314 to SO-05K for example, as a product you getting signature verifiction failure bacause bootloader simply reject flashing firmware from e.g. H8314 to SO-05K product, hope this is clear. You can't bypass that. Phones with "Default security: ON" is protected by signature verification and you/we/I can do nothing about that, the things is digitally signed with a private certificate which only product manufacturer have and one who have licence for that, you can't modify things otherwise you getting signature verification fail as like you getting when newlasher want to flash wrong firmware. Your device model is SO-05K and you must flash only SO-05K firmware and nothing else is possible! Even you think it is the same phone, yes, but product version is not the same!

If I unlock the bootloader, is there any way to force flash a firmware, or change the signature somehow?

If you unlock bootloader you can flash any firmware
You can't change signature any way.

How would I do it then? I would like to be absolutely certain as my options are either paid bootloader unlock or return it. I would like to at least get working VoLTE in the US (XZ2C/XZ3 OEM, and maybe even modem?), and then if possible compatibility with normal H83x4 ROMs (Complete H8314 firmware on the phone I would assume).

I don't have time for this please go to https://xdaforums.com/ and search / ask in forum. If you unlock bootloader you can flash only higher level files like system files, not bootloader and low level things. If you need more info go to forum and ask there, I have xperia 10 and I don't know anything about newer devices, to be honest phones not interest me. How to unlock bootloader -> https://developer.sony.com/open-source/aosp-on-xperia-open-devices/get-started/unlock-bootloader/how-to-unlock-bootloader/ , double check what they say before you proced to unlock
