The problem I had with my 2 byod evo 4gs was not being able to send text with pictures or download the pictures in the received text. Would get the generic network failure error every time. Resets, reboots, and updates did no good. Still no pictures. Of the 3 evos we have, only 1 did the updates to Ting correctly and work perfect. I don't know what the diffrence is between the phones. All software, firmware, etc is the same versions. The 2 with the problem would not allow the APN settings to be saved during the Ting mms setup procedure out lined in the help. So I really couldn't expect Ting support on a byod evo, so I had to help myself. This is what I found. (I want to give the person who came up with this credit,but I not sure if I can or should put a link to his page on this article) I will add it later if allowed. Here is his fix: I changed the mmsc to the Ting mmsc for our use.
Using "APN Backup & Restore," which is free on the market, you need to backup your APN file. Name it "APN-Broken.xml". Connect your phone to your computer as "disk drive" and using notepad correct the code to match what is shown below or just cut and paste.
FIXED Code: <?xml version='1.0' encoding='UTF-8' standalone='yes' ?> <apns count="1"> <apn name="Production" numeric="00000" mcc="000" mnc="00" apn="**1**" user="null" server="null" password="null" proxy="null" port="null" mmsproxy="null" mmsport="null" mmsprotocol="2.0" mmsc="** [http://mms.plspictures.com](http://mms.sprintpcs.com/servlets/mms)**" type="**mms**" /> </apns>
Save your changes as "APN-Fixed" and make SURE it is saved as a .xml. Using APN Baqckup & Restore again, restore your new APN. Perform a soft reboot and you are back in business.
Original Broken Code: In bold is what I think the problem is... <?xml version='1.0' encoding='UTF-8' standalone='yes' ?> <apns count="1"> <apn name="Production" numeric="00000" mcc="000" mnc="00" apn="1**apndroid**" user="null" server="null" password="null" proxy="null" port="null" mmsproxy="null" mmsport="null" mmsprotocol="2.0" mmsc="http://mms.sprintpcs.com" type="mms**apndroid**" /> </apns>
I don't agree with what his problem was in our case, our problem was the APN file was not created and saved. If you watch the backup, it does not backup anything on the phone. Look at the broken backup you made, it does not have a APN file at all! It was never saved! By following the steps above it forces a save. Make sure you disconnect the hard drive mode before you try to restore, or else it won't work. I did a power button restart and all the setting was were the same as the correct phone, SWEET!!!! Everthing is 100% now!
I will send this to Ting support also, maybe they can use it to help us byod crowd. I only done this on my evo 4gs, don't know about the other phones.
A very happy Ting customer,
