Hi there,
can I use firmware from this web site -> http://www.jnhuamao.cn/download_rom_en.asp?id=66
Or I have to use firmware from attachment?
Reason why I ask is because I don't understand this part
"*You need the full firmware, not the firmware provided by the manufacturer as this firmware is only usefull for UPGRADE a genuine HM-10 wich have already a bootloader."
