Hi all,
Just got myself a HTC One a9 from htc.com. Although I got it for a good deal of $200, it only came as a Sprint model. I am using T-Mobile. Reading some posts here and there on XDA, I did myself the following:
1. Unlocked bootloader
2. Rooted phone, sim unlock'd using NV-reader-writer
3. S-off'd using Sunshine
4. Changed CID to MID to that of US Unlocked/Dev
5. Flashed to either the latest 6.0.1 or 7.0 Unlocked RUU
6. Flashed Sprint's radio.img from its firmware package
7. Added T-Mobile's APN settings
And although I am getting 4G LTE and text works, calling doesn't work. Trying to call doesn't make a dial tone, and when people call me it just goes straight to Voicemail.
On 6.0.1, if I go to Settings and try to disable VoLTE, it will freeze up my call settings page. It will then say "com.android.phone is not responding", and I have no way to do anything until I pull the sim card from my phone. I have another friend with the same setup and it's also not working for her.
Anyone with T-mobile service + Sprint phone getting any luck with this?
