Solved My MMS AT&T Issue

Not sure if this will help anyone or not but I read all MMS issue posted here and on the AT&T webside but was still not able to correct my issue on my new unlocked Excalibur. So I finally deleted all my connection settings and rebooted the phone. I then followed the AT&T settings found on the HTC Excalibur wiki and then was able to send and receive. I hope this helps.

[Q] Verizon HTC One (M&) on T-Mobile can't add apn!!

I just switched to T- Mobile and i am able to make and recieve calls. i can recieve texts as well. but i can't send texts and the service will randomly just drop out . i was told to add the t-mobile apn settings, but when i follow the instructions to do so, i don't see "Add" i just see "reset to defaults". can some one help.
Also, someone told me that it would be a good idea to install a t-mobile ruu on my phone. My phone is not rooted and has S-On. also, my bootloader is locked. would i still be able to install it?

see this thread. we're having the same problem.

[Q] Which ROM for an Unlocked HTC M8 branded Verizon, running on MetroPCS carrier??

Haven't received a reply, so I'm updating my question with some new information.
I used Sunshine & am now rooted & s-off.
However, I still don't know what ROM I'm supposed to use:
- My HTC One M8 is a branded Verizon phone, but I've been running it successfully on MetroPCS
SO:
- Do I use a T-Mobile ROM (MetroPCS was purchased by TM and I believe my LTE & 4G comes from TM network)?
- Do I use a Verizon ROM?
Thank you in advance,
Hello,
I purchased an unlocked HTC M8 branded Verizon and have successfully been using it on MetroPCS' LTE network.
I'm considering a different ROM in order to:
- Remove all the Verizon bloatware
- Get as close to Android as possible (I'm dependent upon all the Google apps, gmail, hangouts, calendar, etc.)
- Hopefully get a working FM Radio
From all the threads/replies, I still have not been able to figure out which ROM I'm supposed to use:
- Since my phone is Verizon branded HTC M8, do I have to use ROMs developed for Verizon?
- Which ROM would get me closest to my goals?
Thank you,

Answers to my question
Okay, here's what I had to do to get my Verizon M8 which (thanks to Sunshine!) is s-off and unlocked and rooted to run lollipop (5.01).
1. So the good folk at therootninja.com were able to answer my question and they told me that I have to use Verizon ROMs.
2. I used these instructions to upgrade my phone to 5.01: http://forum.xda-developers.com/showthread.php?t=2727831
3. There are 2 issues I've encountered:
A. My mobile data says "disconnected" and no matter what I've tried, can't get it work.
B. Smart screen security (so my face can unlock my phone) does not work
Does anyone know how to fix "mobile disconnected"? Here's what I've tried so far and doesn't work:
- Used different combinations of APN that I found posted in this forum & via Google searches
- Recovered to my previous version (4.4.4), copied down the APN settings, re-recovered 5.01 and used the settings;
- Factory reset & put in the APN settings
At this point, I'm back to running 4.4.4 because I need my mobile data to work and my next step might be to go back to 5.01 and take the phone to MetroPCS and see if they can get it to work.
I honestly don't know what to do & would appreciate some help from this community.
Thanks in advance,

Some more answers
Okay, so today I restored to my last 5.01 image (twrp backup) and walked into the MetroPCS store.
Here is the APN info the gal, Tiffany, input which worked(!!):
Name: metro pcs
APN: fast.metropcs.com
MMSC: http://metropcs.mmsmvno.com/mms/wapenc
That's it, nothing else. I left the store estatic, drove home and when I clicked the menu, Mobile Data>GSM/UMTS Options, I reviewed the settings, BUT... when I exited the menu an automatic save was done and I lost my mobile data.
After much futzing, to include deleting the APN info & adding a new entry with the same info, I've found that by selecting LTE/legacy 3GPP mode in preferred network, I'm able to get mobile data working again. Go figure! :-?
In any case, the only final two things which are not "perfect" are:
1. Unrecognized SIM error (@DOTT suggested an xml file to edit)
2. Smart lock does not work, facial recognition never appears.
Hopefully someone will read this post & provide a reply. To date, I've submitted many questions and have not received many replies (2).

Getting a Verizon rom to work on another carrier is pretty easy. Since you are s-off you could use qpst to unlock the bands needed to get 3G and 4G working for MetroPCS. If you cannot get data to work, try a Verizon rom from the Verizon section. Verizon phones and Sprint phones have odd mount points,so flashing a rom for a different phone is not recommended. I know from experience on my m7 that a Verizon cannot be Co vetted to another variant. I don't know if the m8 is the same story as I have an AT&T branded converted to T-Mobile for the m8.

Long story short: try the Verizon m8 section instead of this one for help please. The people in this section have the T-Mobile branded m8 and yours is different.

HTC M9 -- Mobile Data Disconnected -- MM 6

Hi All,
I have a HTC One M9 (Unlocked -- S-ON), it was working perfect till I received the official MM 6 update 2 days ago. but after the update is done I found out that the Mobile Data is always showing " Disconnected".
Additional info, this device was assembled in UAE and was locked for Vodafone Qatar and I unlocked it to be able to use it on AT&T (US). I did'nt root it at all but I am ready to if this will fix the issue.
Do you have any solution that can fix this? or you suggest that I downgrade to LP 5.1? and how can I do both steps
I really appreciate your support on this.
Thanks
Best regards
Khaldoun CG

Have you set up a new APN yet ?
If your update did not complete the carrier setup...or if an error occurred...then your default APN will not be chosen.
Set up your APN under network settings...save it...and reboot to test....g

Thanks bro for your help,
I dont need to root my device or downgrade the software

LG G5 sprint locked, desperate need for help

Hi, I have followed the hidden menu apk method carefully which didn't change anything in the phone, I took my phone to THREE repair stores in my country, one of them could manage to do calls with it but no mobile data then the other store updated it I think and nothing is working like at start, PLEASE I BEG YOU for help, I am willing to donate once it is fixed. I was told that some ebay sellers remote unlock it but I don't trust them or at least I want the person to try and then I pay him if it works but I don't want to waste my money.
If it helps, it is now on Software version LS992ZV9, android version 7.0, and there is an update waiting to be installed but I still didn't accept it. I read there is a downgrade guide but how can it help or are there other links or guides to follow? Please guide or help me, it's been more than a year I have this brick.

As I stated in PM upgrade 1 step to ZVA and stop there never again.
The the hidden menu hack will work....

Thanks a lot for the help, I updated from ZV9 to ZVA and the hiddenmenu guide helped me do phone calls but I still can't have mobile data although I set up the APN correctly and I read the tutorial 3 times.
I noticed that in step 8 it says to "Reboot" then if I go in the Hiddenmenu settings in " LTE Data roam config" where I enabled all bands before reboot, I see that "Bar Roam Enabled" is set back to "Disable" so after a reboot it gets disabled and the "mobile network state" in settings is "connecting". Any idea ? Thanks.
Edit1: If I also go in Access Point Names in the normal settings, the apn I put is not checked although in the Hiddenmenu app it is. (https://i.imgur.com/mYwiRB9.jpg)
And usually the carrier in my country sends a settings sms that automatically adds the apn to the phone but when I request it the setrings sms never arrives as if it is blocked by the phone.
I even tried adding the APN of the second carrier we have in my country using my friend's sim card and his apn settings but same results as before.

I don't understand how calls work but mobile data isn't! Does my carrier requires additional settings in the phone to be unlocked or is my phone super locked? No expert to troubleshoot my problem? Please.

Finally fixed! I followed wildantics steps by starting with a R&D factory reset (maybe it is not required so you can try without it first), then a tip to skip configuring your phone which worked from me is to SPAM tap the power, and volume up and down buttons (and I didn't have any sim card inserted).
Use the hiddenmenucall app, in IOT(CDG2), LTE setting, put Operation Mode to Lab Network, reboot, insert sim, reboot. Then in ModemProtocol, RAT Selection, choose GSM/WCDMA/LTE Auto, then in ModemProtocol, Network Mode, choose Automatic, add your APN by going to IOT(CDG2), LTE Settings, APN settings and in LTE Data roam config, enable all the bands.

Which software version did you have when you tried these steps?
