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

Which RUU for Canadian unlocked?

TItle says it all, am using Canadian unlocked version and whenever I flash the 1.80.617 RUU for US unlocked I get this weird bug where I have to go into settings and manually reset default access point names in order to get mobile data. Should I be using international instead? Never got this bug when on WWE edition ROMs. BTW am on Fido network if it matters

I need help on samsung note 4 N910v

My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.

Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.

the fone I have came from china ,am in Africa and remember I told you it was working woth N910f firmware version 5.0.1.All am asking is there anyway I could make this fone work again on Gsm network, cause all it says after re flash is the card is not from verizon

I now rooted this n910v android version 5.1.1 still no network, am in Africa where there is 2G&3G GSM network, how would I make this fone to work again with the gsm network now that I rooted. On the network bar I get a circle with a cross ,how to make this work

- N910VVRU2CPJ2_FullFirmware_NoAboot<--- Full Framework with no aboot so you will not re-lock bootloader, but will unroot and restore back to 100% stock. once your on the full stock check if your connections are working fine, if they are then install custom rom, otherwise change the sim card

go in settings, connections and select network mode to global, should be fine

By flashing stock n910p your network is get locked because you are not using sprint sim card.
Open dialer and dial ##72786# and press "yes" the phone will restart and unlock your network.then you have to make your APN settings manually.depending on your network and you will get only 3g maximum speed 4gLte will never work.
If this does not work you have to root the phone and unlock network by galaxytools app.

Does your phone shows "invalid sim" if not then your phone is already unlocked.
Follow the guide i made step by step in link below only if it shows invalid sim.
once you unlock it then you can flash any rom or stock the unlock will be permanent.

You claim LTE will not work but the N7 ports have LTE working as shown "Device Information" page. How is it that it works on the N7 port but not on stock?

Go to settings/about device/ mobile network type if it shows LTE here then it is getting real LTE signal if not then its fake LTE icon in status bar and its easy to fake it.
If you are in USA then you get high chances to get LTE work.

The "Device Information" page is a hidden setting page and accurately reflects the signal being received. The N7 ports are definitely able to receive the LTE signal on a GSM network as I am on Cricket Wireless. I have even received LTE on stock but it is very hard to do so. I've managed to play with the PRL on stock enough to get it once in a blue moon but have been unable to maintain it like the N7 ports allow me to.

No LTE HTC 10 Sprint Nougat/Oreo !

Ht c 10
Sprint
Unlocked
S-On
When i purchased this phone it was running Viper nougat rom with functional LTE
I updated to oreo firmware and lte gone. It would only show 3g where as i am in full lte coverage zone
I flashed different oreo and pie roms but fruitless
I tried to fix by erasing modemst1 and 2 but it always give error of 35 partition
Today i downgraded to Nougat and erase persist but it is still same
i can only get 3g no 4g or lte
I tried network reset by ##72786# but it eventually sim locked my phone and i had to unlock it manually
Any suggestion or possible fix
Thanks in advance

did you find the answer?

I have also lost connection. Except mine is both 3G and 4G. Oddly I can still call, text, use wifi and putting the sim in my other phone works just fine. I have no clue what's wrong. I've tried everything at this point.
Here's a link to my thread if you wish to follow any solutions provided if someone comments.
https://forum.xda-developers.com/htc-10/help/internet-connectivity-htc-10-please-help-t3946949

It had same situation but eventually I solved it. Now LTE is working. First of all, need to be S-OFF and then after unlocking SIM, you can install any firmware with any ROM that supports the encryption...Either US unlocked or UK International Roms will fix the LTE issue. One thing to notice: you must keep the data partition unformatted for keeping the SIM lock status and need to use SPRINT or VERIZON radio. I am using stock Oreo from with Verizon radio + Magisk.

In addition, I unlocked LTE bands as well with DFS Qualcomm tool
