Ok, for the past for few days I'm having problems upgrading to an Oreo rom.
I have the xt1675 UK based cedric, running Nougat stock. I am actually now in the Netherlands on a Dutch provider and the phone works fine.
However as soon as I flash an Oreo based rom in TWRP, the phone cannot find my network provider anymore and forces me to roam with another provider in the area.
Now here's something weirder. I lost my IEMI when I downgraded my phone to return to stock, however doing the Pixel experience trick restored my IEMI and now I have 3g and an IEMI again.
Now, that's fine I can live with that. So I decided to flash xposed so I can have a little customisation on Pixel experience, but weirdly I lose my network provider again and I am forced to roam again.
Now, I do have a back of the EFS which was 4g ready, but if I flash this it forces me to roam however I have 4g but only in roaming. My network provider is not there is the provider listing.
I am sorry if this post is confusing, it's all confusing for me. It seems I cannnot have an Oreo rom with 4g, as it forces me to roam. However if I go with Nougat, then everything works as it should.
Anyone have any idea what this is all about

I finally got my internet sharing and MMS working on my unlocked Rogers Lumia 900 running on Bell. Earlier this week, I came across this page. http://forums.wpcentral.com/lumia-900/197920.htm. If you follow his instructions (minus the unplugging the cable during the rom flashing), you should have working internet sharing and MMS without having to input any APN settings. The first time I started it with the TelCel rom, I still had to input my APN to get data to work. Then I performed a hard reset by holding volume down, power, and camera buttons. After that, it picked up the correct settings from the sim card and everything works as it's supposed to. The only downside to some people is that now instead of showing "LTE" in the status bar, it shows "4G" and instead of "4G" when you are on the HSPA network, it shows an "H". I think this is a truer representation of the network you are on anyways since HSPA isn't a true 4G network like the American companies would have us believe.
Please note that if you are going to do this, you will lose any unsynced data on your phone and will also have to reinstall all your apps so backup what you need to.

Seems interesting. I will wait for the 7.8 version to come out. I wouldn't want my phone to be stuck at 7.5 for some reason after trying this.

If for some reason it doesn't update to 7.8, you could always just flash the stock Rogers rom back to your phone and then get 7.8.

Have no problem with 4G, sharing and MMS on original AT&T firmware (using my lum with Europe operators).
Could it be a SIM card flag that prevents the sharing, the euro ops SIMS dont have it
Could it be a SIM card flag that prevents the sharing, the euro ops SIMS dont have it but the NA ops do?

May be, may be... But I had problem too with this features, when it worked on a 1st firmware (flashed by AT&T, not by me). Then I decided to flash it on my own via Care Suite (had flashed the earliest firmware, then updated via Zune). Now it works without any problems. After flashing try to not use the Nokia's Network Setup. If sharing would be OK, you could install NNS on your choice
It works for me after doing a hard reset with t) mobile, if I run NetworkSetup then it stops working. If I insert my att sim then it also stops working.

One more datapoint...
Recently unlocked, using Taiwan Cellular unable to tether.
Before installing Network Setup receive message: no data connection found...
After installing Network Setup, "to enable tethering on this device, go to att.com...".
Same SIM card in HD7 allows internet sharing... no problem. So it's not the SIM.
On HD7, data connection shows "H" but on Lum900 showing "4G"... (not a problem, just observation)
Have hard reset with Taiwan SIM, no joy. Reflashed using Nokia Care Suite... same results.
1. It's clear, stay away from Network Settings app. Even overriding APN settings results in same bogus ATT message.
Any point in flashing a pre-8779 rom? One of the TelCel MX or Claro LTE roms?
To flash another RM808 carrier's rom on top of an ATT RM808 device, is it a straight flash with NCS or need to rename files?

Hello, recently I had to reinstall stock tmo on my s6 edge because of a soft brick.
Everything was back to normal, my phone is unlocked to use in Brazil. After a couple of days running stock tmo, the phone stopped connecting to the network I use, but still had data connection. So now I can only use 4g but can´t place calls.
Any suggestions? Should I try different radio firmware? Different ROM?
Thanks!
Problem solved, bad imei.
Bro, the problem is that your phone is locked. I had the same problem and the solution was unlocking the phone. In this comunity there is a guy who unlock phones for free! check his post...

Good morning, I am running the latest Lineage 14.1 rom (14.1-20171204-Nightly-d2att) on the Samsung Galaxy S3 (SGH-I747) phone, this phone is rooted, running the latest TWRP (3.2.1.0) and the I747UCUFNJ2 baseband on this device, this device is fully rooted, and is SIM unlocked for use with any carrier, my carrier is T-Mobile.
Ever since installing this rom, and any roms higher than android 6.0 (I've ran CM 12, CM 12.1, CM 13, SlimKat, and AOSP roms), everything works perfectly except for my cellular data will not go higher than Edge (2G) and my complete cell connection will randomly disconnect for a few seconds then reconnect itself.
I've tried everything from changing the APN settings specified by T-Mobile for LTE connectivity, I've gotten a replacement SIM from T-Mobile, I'm lost at this point as to what the issue could be. According to T-Mobile I do have the BYOD option so unlike some carriers, the SIM is not supposed to be locked to a specific IMEI.
Does anyone have any idea what could be the issue and/or a solution to this? Is there a higher baseband that needs to be loaded to fix this that I'm not aware of?
Thanks for your help everyone.
The phone is also running the latest bootloader?
Yes it is.
I assume the cellular data works properly with a stock ROM.
Does the cellular data work with the sim in another phone? Cellular data works with another sim card in the s3?

Hi all,
I live in EU, so we can use data in EU countries for normal prices. Last summer when i was abroad international roaming worked just fine on stock rom, 7.1. But since then I did not wait for the official update, unlocked bootloader and tried some custom ROMs including Viper 7.1 and the last one was lineage 15.1. And when i was in Austria last weekend, phone was in roaming mode, but i got no data. Mobile data was on, data on roaming was on as well. I double checked, restarted phone and contacted my carrier to make sure I have roaming enabled. I even tried flashing viper 7.1, but with no luck with data.
Sadly I am back home with working domestic data and I cannot test it.. What do you thin would be the best process to make sure to have working data next time I will be abroad? Flashing stock 7.1, then stock 8 and then custom 8 or 9?
Thanks for suggestions

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.

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
