Slight correction of my slight correction. @EskeRahn wins the gold star in simple math today and I lose. 😉

Thanks for the information. And you re-flashed the system partition like this? fastboot flash system_a system.img fastboot flash system_b system.img

But from your previous comment, are you saying that when yo pick "Recovery mode" from the bootloader menu or run "adb reboot recovery", that you aren't presented with a Recovery mode? It just says "No Command"?

So, to be clear, the only way to turn on VoLTE was through the special dialer code, not through some settings menu? And to recap, this was an old SIM that was in a phone (the G6) that was activated for VoLTE usage originally? Way to go!

No idea, but 15x6 = 90, which is sort of close to 100. 😉 If fxtec wants to send me a box, I'll do a good write up on it. 😂

I am totally guessing that there are 15 frames in each box, and that what was laid out represents one box that was emptied. Unless one was taken away for use, there are an odd number of panels, so it wouldn't be from 2 boxes. It could be 3 boxes worth (3x5). That would make for 1/3 my guess. There are 29 visible frames in that earlier picture. If one was taken away, then that would jive with 2 boxes worth (2x15) as well. (or 6 boxes worth)

I am going to say 1680 pieces in the opened boxes with red bubble wrap, and 1080 screens in the stacked boxes.

Let the math games begin on those pictures. lol

Thanks for those steps. I am also wondering if A/B partitioning is coming into play at all here and creating variability in your testing, depending on the state of each partition and which partition you are on when you try the OTA.

Was this the same SIM the AT&T tech tried in the Pro1? May he rest in peace. LOL Yay! I love it when a plan comes together. (I figured an "The A-Team" quote was appropriate for AT&T)

It was more entertaining seeing you do things by trial and error. It also provides insight for fxtec on areas to improve. And your video is the only one showing inserting the sim card, I believe, so that's why I used it as an example. :-)

The OTA downloaded and installed fine? What was the sequence of steps?

What??? Can someone else verify this?

You shouldn't be able to try it both ways, with the keying. Unless the other side of the tray is recessed too? If that is the case, someone needs an empty glove across the face (the engineer who designed it). 😂 I don't see many people letting this thing go! We've all been psychologically programmed to be addicted to it before ever getting our hands on it.

I have a cellular router that takes a larger SIM size than the AT&T SIM I have for it. I had to use an upsizing adapter for it and that adapter and/or the SIM slot would allow the SIM to fall out/move around too much, so tape was used on the bottom side of the adapter to keep that little bugger in place. Similar (no pun intended) deal, where it didn't really snap into the adapter. I'll be able to use that AT&T SIM to test the Pro1 too, but only for data. That SIM won't allow phone calls, as it is technically a tablet data-only plan. I do need a Pro1 to conduct that test though

Thanks for the picture. I just assumed it wan't keyed, because it took Craig a bit to get it in there and I figured it wouldn't fit in there wrong if it was keyed. The keying isn't as apparent when trying to put the SIM in the combined SD card location, it seems.

Ah, that makes perfect sense. Yeah, that shouldn't be a problem with this phone, obviously. I see it as him trying it phone face up at first, but the SIM falls out (before the timeframe I link to in the youtube video), so he then flips the phone around, so it is face down, and then inserts it with the SIM face up. Maybe the instructions are wrong? LOL I could be seeing it wrong in the video, but that's what I thought I saw.

Yep, that's my guess too (SIM inserted incorrectly). That's why I figured he could mimic what Craig did. I was very surprised when Craig was doing it that the SIM tray isn't keyed. Seems like something fxtec should consider down the road. Maybe even for later production unit Pro1s, if they are able to get different trays. Did you have to add a custom AT&T APN, @Hook? And was your SIM brand new, or was already in an AT&T phone before?

As per @Waxberry's post: If it is a newer phone, the bootloader will be locked by default. If you need to unlock the phone to get it to work on AT&T, then you might need to go through that process. There are multiple other people who have gotten the phone to work on AT&T, but maybe they have phones that came unlocked? Maybe the tech inserted the SIM incorrectly? I believe @Craig is on an AT&T MVNO (FreedomPop). Here is how he inserted the SIM: He had to add a custom APN though too.

You can try entering "default_password" at that screen, but I'm not sure if it is going to allow that when it expects a PIN.

You could also see if a factory reset from recovery affects the issue in any way.

I was thinking that maybe something done beforehand could have affected the problem in some way. But if someone else can verify that flashing back to stock, using the information in this thread, causes the same invalid PIN issue, then that might reduce the chance of it being something done earlier, especially if that person didn't root or anything else. Since we can't back up userdata properly with TWRP yet, I guess your option is to use Titanium Backup to backup the apps and then restore them after step 3 up there (fastboot erase userdata)? We don't know yet if flashing the OTA causes

It might help to list the steps you took from the time you got the phone and rooted it and unrooted it and tried the OTA and then afterward too, in the way you listed above. For instance: 1) got phone with unlocked bootloader -> flashed modified boot.img to install Magisk -> did xyz in Magisk -> uinstalled Magisk without rebooting -> tried OTA -> got error QRS 2) x -> y -> z etc I'm just making up the first series up there, by the way.

Yeah, I saw that too, but I was hoping for a fancy screenshot of it in action and to see if the multi-keypress thing was a problem with it. Us delayed-Pro1-shipment customers have to live vicariously through you have-it-in-my-hot-greedy-hands customers. 😂 It is great that the old games are so relatively small that a person can have them all at their fingertips.

That would be true of any provider where not all the bands are supported and a person only has unsupported bands in their location. We are talking about a specific issue of T-Mobile in Chicago, IL. But to attempt to get T-Mobile working at all, it seems that the APN needs to be added manually. The APN to add has been provided in another thread, but here it is again: https://support.t-mobile.com/docs/DOC-2090
