Hi, thanks for all your work on these ROMs!
I tried to flash your 18.1 ROM but it did not work on my T889 (flashing failed). This 16.0 ROM did flash correctly, and performance and battery life were good.
Unfortunately it has modem crashes sometimes which makes me have to reset the phone often. And also, when I make calls it switches from LTE to the 3G network instead of 4G. After a few days my phone stopped making calls and data stopped working.
I had to call ATT who told me the system automatically disabled my phone because it detected either a non-ATT phone or a phone using the 3G network which they are shutting down next month.
So I'm not sure if there's a way to force 4G only, disable 2G and 3G, or what but just thought I'd mention it in case you or others know of a way.
Oh, and the Camera app is a Google app (with location stuff built in). And location had to be disabled for the web browser. Just a note for others avoiding Google/telemetry stuff.
Thanks again for all your work, it's really impressive to get a modern ROM working so well on such an old device. Hopefully I can figure the 3G switching problem out (or maybe it can be configured in the next ROM release if there is one). Also, thank you for the TWRP, I was able to update to 3.6.0 and it runs great (also gives me back USB UMS Mass Storage connection which is awesome and has been missing from TWRP for a long time on this device).
