Testing: I (and my wife) continue to not get some MMS messages. We both now have OP6, both using UT, have the same carrier, and APN settings, the same as earlier detailed. 1) with my WIFI on I can not send an MMS message. It fails to send. 2) with my Wifi off I can send my wife an MMS and she can receive it. If Wifi is off the MMS comes through just fine. If her Wifi is on she gets Oops and the process described of switching Wifi off and Download retrieves the MMS successfully. 3) I created an MMS for my wife and to a secondary Google Voice # I have for myself (group message). Both of these numbers are in our contacts. With Wifi off for both of us, the MMS was sent AND received. I did not need to have a 'group' set up on either phone.
4) My wife has received Oops messages for MMS sent to her as a group message from her sister and 2 daughters. All numbers were in her contacts. These messages are not retrieving with the Downloads action. I will next set up a group with them to see if that makes a difference BUT why does my previous group MMS come through and this one does not? What are the variables? Is it because some of them use IOS or Android vs UT? Is it Carrier specific if it works well or not?
I just thought I would pass along this 'testing' to add to the confusion. I have not yet viewed any logs or wget the failed MMS. I may get there soon but previously when I did and opened the file with Seabass the file showed empty. I hope this has been helpful but my wife is very frustrated that she is not getting her pics of a new puppy, lol.

@antidroid 1) Will this also work on an OP6? 2) I am not sure of the process. Where do I run the flash_all.sh, from my laptop terminal or from the phone? Do I need to download the files to my Linux laptop or will they be pulled in when the script is executed? Sorry I am pretty non-technical and new to all this but want to get my OP6 back to factory so i can try to install LineageOS.

@rik I had created a group on my wife's phone that included my wife, her sister, and our 2 daughters. I sent a picture to them with a text message saying it was a test and asked them to reply to the message with a picture of their own. My wife's sister just replied to the group message with 3 pics and some text. It came through just fine. It seems that as long as it is in response to that same group or that group thread then it is OK.
A problem I believe this creates is that the only access to this group they have, in order for my wife to get the message, is by responding to that specific thread. I am curious, if one of them were to delete the thread and then send a message to the same members (a new thread) will my wife then receive it or will we be back to where we started? I am waiting to hear from the other recipients. Also if any one of them were to add an additional person I am not sure what will happen since they will not be in the group I established? I guess one step at a time.

@rik said in MMS success and failure:

Please confirm: did you just use "+" to add 2 recipients? If so then you just sent 2 simple SMS. To send a group MMS you need to click the "people icon" to the far right in the "to" field, then set up the group, then you can send to it. So the fact that you didn't set up the group on your sending phone makes me suspect you did not actually send a group MMS?

I didn't realize there was a difference between the To: line and the Peoples icon . After more testing, you are correct. If I add two contacts in the to-line it does work but if I use the 'peoples' icon and then add them there it does not go anywhere - no failed message-no Oops message- no nothing? I expected something....

I did create a group using the 'peoples' icon and sent a picture to them asking for a response with another picture attached if received. I will report back any response received.

I also find it odd that my 'group' is not really saved somewhere for later use like a distribution list can be in other systems. Seems like once the group message thread is gone/deleted then the group is gone and needs to be recreated for any future use.

@ronbillock In addition, I did find out that this failed message was sent as part of a group message.

@applee I just received a failed MMS. I shut off Wifi, waited a couple of minutes, hit Download. Nothing happened. The download button is now greyed out. I looked at the nuntium file (attached) and did wget on the HTTP (attached). I used Seabass2 to view the file created in my home directory. When I open the file (mm?T=m-6-262-2-993f40-78) though it says the file is 1.1mb, again it is blank like before.

@applee well I am willing to do what I can to help but I will be on the road the next couple of days. Maybe I can re-engage when I have fresh 'failures'.

@rik I downloaded Seabass2. I have never used it before but am familiar with nano. Unless I am doing something wrong, it appears the file is completely empty. Do I have to type anything in the Seabass window to get it to read the file or should it just open up when I select it?

@applee which log(s)?

@rik is this what the output should look like?

This is greek to me. If this says nothing, is there a way to clear the log and then I can send a message from my wife and then after it 'oops' try and get the log again?
