Can't make or receive calls after hard reset

[Guest krash_control]

Hi

I have a T-Mobile branded i900 which I flashed to the latest release and the version is now:

PDA: i900XXHJ4/MSHJ1

Phone: i900XXHI5

I also unlocked it using the instructions from http://www.modaco.com/content/i9x0-omnia-h...omnia-it-works/ and it has been working great. A couple of days ago I decided to do a hardware reset by going into Settings > Hard Reset > Reset Main Memory only which seemed to work, but now I randomly cannot make or receive phone calls. I have done the following to try and fix it:

* Soft reset

* Hard reset again

* Took the battery out for 30 seconds

* Took the battery and Sim card for 30 seconds

* Tried the SIM in another phone (which works fine so it's not a SIM issue)

* Hard reset then try the unlock process again. Says phone is SIM unlocked but still can't make calls

* Set it to flight mode then back to phone mode

* Manual selection of the GSM provider by going into Settings > Phone > Network > Set to Manual and picked Virgin.

* Set Time Zone Updating to Manual by going into Settings > Clocks > More

I'm think next I will do a full hard reset including My Storage and if that fails then I will flash it again. If anyone has any other ideas that will help, it will be greatly received.

Not sure, but maybe you have to call the T-Mobile programming number for an updated PRL, or phone settings reprogram.

Thanks for the reply but what is the programming number? I'm also not with T-Mobile, it's a just a T-Mobile branded phone I got off ebay. My network is Virgin (although they use the T-Mobile network).

I've just done a full hard reset by going to Settings > System > Hard Reset > Clear Memory and I can make calls again. Will see how it goes during the day and post an update tomorrow.

Well after the full hard reset the phone was working but would switch off the phone radio after a while so I followed the tip in another post to go into Settings > Clocks and Alarms > More > Set time zone update to manual now its working fine.
