Hero keeps entering "Emergency Callback Mode", cripples data/calling
 

My Hero keeps entering a weird "Emergency Callback Mode". It happens all the time randomly, many times immediately after answering a call, and EVERY time I try to change my roaming preferences. This mode kills all active data connections and only allows incoming calls. It is supposed to enabled itself for 5 minutes after calling 911 to allow rescuers to call you back, find you with GPS, etc. I have never called 911 on this phone.

I have checked everything I can think of and it still happening. I am on the latest Sprint radio and have tried on multiple different ROMS. I did successful OTA PRL and Profile updates, still didn't fix it.

I have found the most reliable way to clear this emergency mode is to open QPST service programming, read all settings from phone, then just write them back. This resets the radio and it works fine for a while.

I tried researching this a lot and haven't found much helpful information, I would be greatly appreciative if anyone could suggest anything else. Thanks

Just wanted to chime in and say I was able to fix this. I did a ##786# and reset to factory defaults. Then I just re-entered my NAM and data profile info and everything seems to be fine now. Oddly enough, doing the ##786# retained everything including meid, recovery, ROM, etc. All it did was reset my CDMA options and fix the problem. Hopefully this will help someone out there!
