You can only rebrand your phone with TWRP. For this you need an unlocked bootloader and the unlock progress causes a factory reset.
So, without factory reset you can't rebrand your phone to C432.
If you installed a C432 firmware you can relock you bootloader, but I don't know if the OTA Updater recognize a different between locked and relocked.

You can try this. It worked for me as Updater very good, because I can't OTA update because, I rooted. But this tool has also a rebrand option. If you need any help using this, reply or send me a message.
