Sm-j700m cpu is arm64 but only allows 32bits android on it.
I thought that, if the bootloader could be replaced or tweaked (change some bytes on it), it could allow 64bits android (lineage os 64bits build) to be installed on it.
But these are the only clues i got til now, any tips? Can it be done? Is there some software for that device, or other devices, that could do that on that device?
