No hotspot on note 9 after U1 firmware flash - Samsung Galaxy Note 9 Questions & Answers

I was using straight talk cdma with my unlocked nexus 6p and the hotspot was working great as always, then I get a new "sprint unlocked" note 9 today, flashed it to U1 firmware to get it to work with the same sim that is in my nexus and boom everything is working as expected but I lost hotspot functionality. I can turn it on and it acts like its working but my computer never sees the network. Any Ideas? I've been out of the game for awhile and I didn't know much to start with lol. Any help is much appreciated. This phone is sick, if I just had my hotspot back I would be in business. Ran though the process again with a factory reset but no dice.

Bump. Tried a couple more things with no luck, I wonder why hotspot worked so well with the same setup on the nexus phone but just fell completely off with this one. I have heard that you could lose some carrier functionality when flashing U1 like wifi calling, visual voicemail but I never head anyone mention losing the hotspot. This is one of the few features I would have a hard time living without since I've grown so used to having it. Any suggestions or something to try?

I had this issue when I had a tmobile note 9. Changed the apn type to default,supl,mms and it worked. Not sure if that really did anything but had the exact problem you are having. Maybe manually entering the apn is an answer for you.

Had this problem again after rolling back and doing the official upgrade. In APN Type, put * and save the apn. You will likely have to put in all new APN settings for your carrier. I couldn't edit the automatic one. Once doing this, tethering worked properly!

I don't have the option to add a new apn, its grey-ed out and I can't edit the automatic one.

MMS not working no matter what I do.

I've been messing with this phone for a week since I got it and I've tried every APN setting I could find. Does anyone who is using the phone on AT&T have MMS working and can they share with me their APN settings? Also of note, I have made sure my plan is a smartphone 4G plan with att. I've talked to 10 people at ATT and they really don't know what they're doing. If I can't get MMS working I'm afraid I'm going to have to return this phone.

Go to Settings>Xperia>Internet Settings
Follow the instructions which will download an app that will install the proper APN settings. I fought with the same issue and this made all perfect! MMS to your heart's content.

[Q] Straight Tall APN issue with SM-910T

So I recently got a T-Mobile Samsung Galaxy Note 4. As we know, it's unlocked 100% without any special root methods or entering in codes into the dial pad. With that being said, I popped in an LTE Straight Talk SIM card, transferred my old number to the new SIM and configured the APN and for a long while it was working fine with no issues. Then out of the blue, I had no data. It absolutely quit without warning. I go to check the APN settings I had previously and they were gone. I had redone everything and saved the settings. However, when I go back out a menu, no Straight Talk APN. I did the same thing again....and once again no APN settings. Just the default T-Mobile LTE APN.
So I'm at a loss. It was working fine previously and now I cannot set APN settings. I have reset the phone more than once (reluctantly). Any thoughts? Any help would be appreciated since I'm paying those bastards $45 and some change a month for service I cannot get. Also as a note, I can receive and send text messages with no problem. Calling number results in "you are not registered on a network," but I know the fix for that.

Try setting the APN with this app https://play.google.com/store/apps/details?id=com.tracfone.straighttalk.stdatasettings
Sounds like your phone got black listed. Did you buy it from Tmobile? If you bought it from some one else it was either a stolen phone or the previous own stopped paying for it.

I had bought the phone from a local gas station owner (who had 2 other T-Mobile phones with him). It was working while he showed me the phone (he had gotten several text message and Facebook updates). He then reset it. I bought a Straight Talk SIM kit and went to work. I had working data until the next day. I had played around with some more internal settings, like updating the touch sensitivity and more. Everything was working until I refreshed the Wi-Fi antennae. Don't think that would have anything to do with the 4G/LTE radios or regular antennas. Overall, it was working, so I don't see how it could just magically stop.

If he bought the phone on a lease from T-MOBILE and never fully paid it off T-Mobile would black list it. Or if he sold you a lost\stolen phone.
You can contact T-Mobile or check the IMEI on one of those checker sights to see if it has been blacklisted.

You can check to see if you're blacklisted by visiting the T-Mobile website and using their IMEI checker. If you're blacklisted you would not be able to place calls. I will attach sample AT&T APN that works for me. I'm on Cricket and not StraightTalk but it may work for you.
For all who helped out on this post, THANK YOU! I figured what my issue was. SIM card is fine and the data settings work as long I don't configure the MCC & MNC settings. Changing the MNC from 260 to 410 is what caused my saved APN to disappear. Not sure why that happens, but if any of you have an idea of why, direct me to the thread that explains this or if you know, quote this reply. And another thing, I am able to send texts and make calls, but due to the location I was in, texts sent at half the speed of smell and making a call was impossible due the phone claiming I was "not on a registered network" even though ST is a network (duh). I have no service issues on my Note 3 N900A when I that. Anyone think it could be because AT&T's device antennas differ from that of a T-Mobile Note 4? Personally, I don't think they would since they are both GSM and operate on the same bands (I would think), even though the Note 4 has "newer" technology. Not really worried about data, texts or calls since I have Wi-Fi in said location.
Again, thanks to those that helped me out. And, again, if anyone has any ideas to the information said above, by all means give your say or direct me to where there is substantial info.

Updated to 6.0....lost tethering. [METROPCS]

So here's the deal.....I eagerly flashed 6.0 on Monday as soon as I got home from work. I'm on the MetroPCS $60 unlimited LTE plan w/ 6 GB of tethering.
After the update, I can't get tethering to work. It will turn on, and from the phone's perspective it works fine. I can connect to it with my Nexus 9....but no internet. I've rechecked and reentered my APN setttings several times now, still nothing.
Also relevant: I was unable to tether for a while on Lollipop. I rooted for a while and used a 3rd party app, which worked fine. Eventually I unrooted to use Android Pay, and found a change to the APN that made tethering work 100% stock(it involved changing the MVNO ID field to 6D38).
Everything was great right up until 6.0. I can't figure out what 6.0 changed that is making it not work. Maybe a permission? Was it the updated radio?

edit you apn. many tmo users got wrong apns on marshmallow as well. since tmo owns metro pcs, tmo was missing apn protocol which is ipv4/ipv6.
I already have that set.
Got it working. I ended up editing the build.prop and adding the noprovisioning=true line.
Nexus 6
Can you tell me how to do this on my nexus 6

Getting CDMA networks to work on Nougat roms

On a couple threads I’ve been asked how I got my N5 to work on a Nougat romon a CDMA network. I’m posting this in the hope that more people try it, and we can figure out a reproducible way to make it work for anyone. I can’t figure out why it’s working for me, or what exactly did it (that’s why this post is so long).
Since N5 didn’t get the official update to Nougat, there are supposedly some blobs needed for CDMA networks that never got upgraded. My understanding is that this is the reason it doesn’t work automatically. GSM networks work fine.
I’ve been running LineageOS14.1caf and it’s been stable, always connected to Sprint (via RingPlus, an MVNO). Data and everything else stays connected through reboots and updates. Others have been able to connect N5/CDMA on Nougat, so that’s not a big deal, but they don't seem able to stay connected. It’s lost on reboots, and you have to do things to get it back. Or you can connect, but only have phone and texting, no data.
Most of the time if you flash a custom Nougat rom on N5 and you’re on a CDMA network (like Sprint), you’ll get a message at the startup screen that says ‘no sim card detected’. The data icon on the status bar will be a grayed out icon with a slash through it.
What I’ve tried to get a stable connection is like throwing spaghetti against a wall and hoping some of it sticks. I just kept trying different things until it worked. It’s not automatic. You have to try a lot of different things. On 14.1caf, something I did stuck. On other roms I’ve tried I’ve been able to connect to Sprint, sometimes get data, but it doesn’t stick for long.
At the bottom are links to some zips I’ve used that seem to make a difference.
The first step is to get a connection, but that’s just the beginning. There are a couple ways I’ve gotten this to work on different roms.
When you flash the rom, also flash the second and third zips below if you're on an MVNO. The first one is an aroma installer that lets you choose your MVNO provider and installs an apn that may work, the second supposedly does something to update the prl (I’m not sure if it makes a difference, but spaghetti).
This may get you a connection, either at the startup screen, or once you pop out and reinsert the sim card. The grayed out icon w/slash will become bars, assuming you’re in range of a tower. If this doesn't work, maybe try another rom, or try the other zip.
Alternately, you can flash the other zip (sprint.zip) from the post below, I’d try the other ones first, unless you’re on Sprint directly, not through an MVNO. You may come back to this one later.
When I flashed the sprint.zip first on one rom, I got a connection but it wouldn’t initialize until I flashed the other zip with the aroma installer. However, if you’re on Sprint and not an MVNO that uses Sprint, you may only need this one.
From there, once you have a connection, go through the google setup, and if you still have a connection check to see if it includes data. I have a couple ways to confirm this. 1) Turn off wifi, and you should see 3g or LTE appear next to the bars. 2) Use an app like Internet Connectivity Test to confirm connection. Or open a browser.
If you have data connection, reboot and see if it sticks. If yes, use as is for a while and see if it keeps sticking.
If a reboot loses data, or loses the connection, you can sometimes get it back by removing and reinserting the sim. When this happened to me, I then worked on finding an apn that would keep it stable. When I first was using 14.1caf, it wasn’t stable, I got it stable doing the following.
Flash the sprint.zip. Reboot and go to Settings/Wireless & networks/More/Cellular Networks/Access Point Names. You want to end up with only one apn on the list. If you flashed the sprint.zip, one in the list should just be named ‘Sprint’.
Open the other apn’s one by one, hit the three dot menu, and Delete APN, until only the Sprint one is left. Or, you could create a new apn with all the following settings, just be sure it’s the only apn when you’re finished.
Either create a new apn or open the Sprint apn and use the following settings. You may only to change the two protocol settings.
Name: Sprint
APN: Sprint
Proxy: Not set
Port: Not set
Username: Sprint
Password: *
Server: *
MMSC: http://mms.sprintpcs.com
MMS proxy: 68.28.31.7
MMS port: 80
MCC: 310
MNC: 120
Authentication type: PAP or CHAP
APN type: mms
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
APN enable/disable: (grayed out, or APN enabled)
Bearer: Unspecified
MVNO value: Not set (grayed out)
Hit Save in the three dot menu.
Back out.
Is ‘Sprint’ the only apn in the list? If yes, hit + In APN settings, then back out. This seems strange, but more than once it was like turning on a switch, and I got data connection instantly after hitting + and backing out.
Other things that worked for me at different times early on to restore a lost data connection: Reset Network Settings. Reflash the zips below. Update prl, if it works. Repeat all the above. Spaghetti.
If you’re comfortable saving and restoring backups in TWRP, then you’ll be comfortable trying this out on a few roms to see if you can get Nougat on your CDMA network on N5. If it doesn’t work, you can restore your working rom. It’s been worth it for me, I think Nougat’s an improvement over MM.
14.1 Roms I’ve tried this on: LineageOScaf (success). DarkRom (success, but couldn’t get it to stick. Maybe could with more effort). LineageOS noncaf (success, couldn’t get it to stick). PureNexus (no success).
Yeah, this is a complicated workaround. If a developer would figure out a way to get the right CDMA blobs for N5 on Nougat then it would just work out of the box.

An update: I was also able to get this to work on 14.1DarkRom caf version and am now running it with a stable connection to RingPlus/Sprint, everything works fine.
There's one trick I forgot to mention that I learned from another thread: Flash the last stock 6.0 rom, get your network to connect, and save the EFS partition in TWRP. Supposedly some network info is on there. When you flash one of the 14.1 roms, restore that EFS partition at the end before booting.
Someone in a related thread (https://forum.xda-developers.com/go...ix-sprint-data-to-custom-roms-t2541924/page11) used the procedure I posted above including the EFS partition trick and got their phone to connect with Freedompop/Sprint, so it's reproducible after all.

Thanks for working on this. There are probably only 5 people out there who have Sprint and want to use Nougat on the N5. I got data working on PureNexus7.1; however, I have to do the pull sim card trick and then it only shows a "4G" icon instead of LTE. I had similar problems with cyanogenmod on my Galaxy Nexus (N3) back in the day.
Does LineageOS and DarkRom show LTE or 4G? Thanks again!

Both Lineage and DarkRom (and the unofficial cm caf) show LTE on my phone, never saw 4G. It may be a carrier thing, not sure.
Yeah, it's surprising there aren't more people wanting to do this. I guess it's a combination of an older phone (Nexus what!!!?), few Sprint users, and honestly it can take some work to get it functioning. Nougat is such an upgrade for our phone, though, it's worth it. Feel free to add anything to this that helped you get it working.
Has anyone gotten this to work on Nexus 5 with a nougat rpm on Freedompop Sprint? I tried the two zips and service connects for a second then drops. The sprint zip won't download. Anyone have another mirror for it?
Most "fixes" don't work.
They either never worked, or addressed something that was broken again in a later build. I went through dozens of wipes, flashes, and system tests to get CDMA working 100% reliably for me... and then a patch was merged that changed something.
You could get CDMA working up to September (?) 2016, but builds after that (CM13, CM14, and LOS14) changed CDMA again, killing previous fixes.
I have FreedonPop, and the best thing to do with that service is trash the Sprint CDMA/LTE SIM and get their AT&T GSM/LTE SIM.
Yeah, you get less free data, but it fixes all SIM and connectivity issues, and even gets GPS fully working (another problem with using Sprint).
I can just flash CM/Lineage and have a working device on first boot. That's such a nice feeling.

Yeah, I think I may have to switch to their ATT or T-Mobile GSM/LTE SIM.... I'm not too surprised that CDMA isn't working properly, I've always hated CDMA service to begin with, haha. I only went with this originally because it was 500mb for free . Time to go order a GSM SIM card from FreedomPop. Any good deals on those right now? I'm not trying to spend $20 on one, if I can avoid it...
EDIT: I found this website (great info for FreedomPop! http://www.cranialborborygmus.com/FreedomPop-LTE-gsm-sim-review.htm Within that site is a link (http://www.cranialborborygmus.com/buy/FreedomPop-LTE-GSM-sim) to get the ATT LTE FreedomPop SIM for $1.99 w/free shipping +1 extra GB of data on top of the first month's 1GB. You just have to remember to switch your service to the free plan before the first month is up, else it will auto-renew at $27.99/month)
With Ringplus folding I'll be going to Mintsim, which uses T-Mobile, a GSM network. No more CDMA for me, for now.
I've been running this on Sprint without a hiccup for weeks now, never had to scramble to fix things even once. Everything comes to an end.
It doesn't work for mine, maybe I'm doing something wrong?

Unlocked US Note 9 loosing mobile network

Hey All,
I just got an unlocked US version could silver note 9. I am on N960U1UEU1AEL1 firmware and T-Mobile network. I seem to have an issue where the phone is dropping connection. It shows the LTE icon in the task bar but I cant connect to the internet. I have to restart the phone in order for it to connect. It seem to be tied to a wifi or something along those lines. If I connect to a wifi then walk away from it, the phone has trouble picking a tower but it shows that I am connected to LTE. I tried adding new APN settings but it defaults to the T-Mobile APN. Do I really need to flash TMB firmware, I really liked the unlocked version without all the bloat. All help is appreciated.

Have you tried resetting the network settings? That's where I would start. Could be a bug with your software. If that doesn't work try rebooting the phone into recovery mode and wiping the cache partition the reboot. If that doesn't work back up your data then factory wipe the phone.

I haven't tried resetting the phone yet. This is my first phone that is not rooted and I started using Blokada from day one. I wonder if Blokada is causing this, hmmmm.
Ok, I did some more research and it sppears to be an issue with Blokada version 3.6.
