Hmmm, crickets....guess no T-mobile people that can comment have read this
This sucks because I cannot use WiFi at home if I want to receive voice calls - once WiFi is turned on WiFi calling TRIES to enable, and fails.
Anyone calling goes to Voicemail without me ever seeing it ring......impatiently waiting for either Tmobile to update firmware to one with bootloader version 2 or for me to pay off this phone so I can buy another
while I love the S8 Active I now wish I'd have gotten an S7 as I was able to get firmware for a pair of S7's and flash them from ATT models (SM-G930A) to T-Mobile models with Tmobile factory apps (G930T) and friends say they work AWESOME now - no such love for the Galaxy S8 Active
Great questions, but unfortunately not the best news for you. As an alternate carrier, we don't develop any bootloaders, firmware changes, or any updates directly. I didn't see a very active root community for the S8 active, but I also didn't do a huge search since we don't technically support root. That said, that's probably the only real option, but as mentioned, we don't officially support that as a carrier.
I wish I could offer you a better solution.
I'm not looking to ROOT the phone, just load T-Mobile firmware onto it so it looks just like a T-mobile purchased phone.
I did this with a couple S7's with no issue but the bootloader was at the SAME version unlike mine
OH well I guess I just deal with using EITHER WiFi OR cellular but not being able to take calls with WiFi on until such time as TMO releases newer version and it's got BL 2 and gets posted on xda-developers forums ...not the best solution but at least I have FIVE BARS of signal at home unlike those OTHER guys who only gave me 1 at best....
