[HELP] Change device ID without flashing

[bane022]

Hello, does anyone know how to change device ID on Tanix tx3 mini with atvexpiriance firmware 4.2?
I am using IPTV app for a 30 day trial period which is registered through mobile phone number, but for activation every next 30 days, i need to flash firmware (because i get new device ID) and if i unchange my ID (if a do not flash device), app recognize same ID which is probably registered in their system and forbidden for next activation
I think there is a easy way to change it, beacuse flashing firmware is a hard way to change id. THANKS, IF ANYONE KNOW EASIER WAY!
