Would be interested in what folks who have flashed this think. Benefits and issues. Thanks much in advance
Been running it since a week or so after release...
Benefits: Minor battery life improvement after several days and locking the mode to CDMA/LTE, battery seems to be significantly better in areas of good signal and worse in areas of poor signal, for me it's an overall plus most days. No data stall issues, not once since going to global mode ROM. No stupid location settings pop-ups every time you change a setting.
Issues: (Car?) charger is not recognized occasionally with screen blanked, unblank screen and it is recognized right away. Manually toggling Mobile Data or WiFi on/off causes reboot (hasn't done this since a factory reset 2 weeks ago, may have been an app conflict and not a ROM issue)
So basically unless you are going overseas (or wish to experiment with AT&T/other SIMs), use Skype, or have lockup/data stall issues, there probably isn't much advantage to it at all, and on the downside unless Verizon/HTC happen to release this as an OTA ROM (unlikely), you will not get further OTA updates since it is not an official Verizon-supported ROM.
For me the main reason for changing was the data stall issues on the official .12 ROM, I got it several times a day, since I switched to the Global Mode ROM it hasn't happened once.
