Thread: What is keeping me from getting MMS on the Arrive...

Well this post gave me hope that we could get MMS working on the Sprint HTC Arrive.

Confirmed on a Samsung Focus

Confirmed this process works, but it takes a little bit of work. Below is a simplified step by step process that worked on my Mango phone.

1. Developer Unlock your phone. I used Chevron WP7 ($10). Make sure to follow all the directions on their website. This is needed to sideload apps.

2. Download and install Windows Phone Power Tools onto your PC from the devs site

. This is needed to easily transfer files from your computer to an application installed through the Power Tools.

2.5. If you have a Samsung phone use the Diagnosis app (install it by calling ##634# on the phone) to check your current internet/mms settings. Check the settings by typing *#9920# INTO the Diagnosis app. Take mental note or write them down in case you want them later.

3. Interop Unlock your phone. I suggest you install the app through Windows Phone Power Tools, makes for easy management. Follow the directions on Post#1 of thread number

. This is needed to sideload apps that use the interop flag (ie native code). If you are changing your internet/MMS setting right away you won't have to worry about fixing your internet settings as suggested in this thread.

4. Install the On-Device ProvXML tool from thread

using Windows Phone Power Tools (necessary to add your provxml file).

5. Using the provxml example files from posts in this thread create your own file with the settings for your provider. Experimentation really is the key here, it WILL eventually work with the right settings in the right spots.

6. Using Windows Phone Power Tools, copy (Put File) the provxml file you created for your carrier into the On-Device ProvXML app storage.

7. Open the On-Device ProvXML app and swipe left to the ISO STORE screen. Long press the file you just copied and select EXECUTE. The app should tell you it executed successfully. Close out of the app.

7.5. If you have a Samsung device check your connection settings again to see if they changed to what you wanted. This is good to check in case a change you made in your file did not do what you wanted it to do in the settings.

8. Try sending a MMS! If it doesn't work, keep working on your provxml file and repeat steps 6 and 7.


My first post here in xda-dev, I hope it helps the brave souls using WP7 on different carriers!

I'll upload my provxml files for Red Pocket Mobile/JOLT and have a quick chat about things I've noticed in a post to follow.

This was from XDA.

Basically I already had the phone registered as a dev phone. That is a good process as well. What it boils down to so far is that the fact that the HTC Arrive is not a global phone and doesn't have a GSM radio. This prevents some methods of unlocking the device from being done. You may be able to downgrade the phone from Mango, chagne the MMS settings and then upgrade again.

Another thing you can search for is a way to route data through a proxy for Windows 7 Phones (wifi is easy... talking through a cellular network).

I'm totally burned out with long processes on phones that aren't even popular! Good luck if you try and please post up.
