READ CAREFULLY!!!
You flash these files at your own responsibility!
I am not responsible for any damage that might
be caused by flashing (bricked device, lost data, ...)!
Flash only the correct files for your phone!

Since no custom ROM for the SM-T585 on this side updates the baseband/modem, here you'll find all availiable ones from the original firmwares. With a new baseband/modem you might benefit from a better cell reception and / or less power consumption. Feel free to test, which one works best for you!
