Hello,
Today I flashed a rom from http://forum.xda-developers.com/note-2-tmobile/development/rom-team-ub-rom-t0lte-t2974731 and it killed my network. Before flashing I was able to get a signal to T-mobile's network (calling, texting and data). After update, it couldn't find the cellular network (stuck on the screen looking for a network). Going into settings to auto-register on the network also didn't work and getting the message "error when searching for networks". Then I tried to flash stock with odin but it didn't work, gets errors of writing on boot.img and system.img using the stock roms for Jan 16, 2013.
My phone is Note 2 (SGH-889V). originally T-mobile, Wind (Canada) on T-mobile sim.
Please help.

I recently just got a plan on the Canadian cell service provider, WIND, on my Roger's phone. I unlocked it and make it able to use AWS bands, which is what WIND is on. The phone read WIND fine when I was getting the plan, but only a few hours later the signal died and now I'm getting "Your SIM does not allow a connection to the network".
I tried using ODIN and flashing back to stock 4.1.1, but that has not worked. I don't know what to do right now.
I also tried turning the radio on and off, and that has not worked.
I'm stumped. Can anybody help?
You have to reapply the AWS mod the moment you flash another modem.
My phone was was modded and has had SEVERAL different modems and never had to re apply the mod is a hardware firmware flash and should stick. You could try I suppose but it may b with all the ownership changes with carriers here they may have changed frequencies. Like Telus screwed 90% of Public mobile customers.
When I modded mine I went through QPST there is a thread in development.

Have you tried changing SIM Cards?
What about booting to recovery and performing a factory reset?
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 the last week i update the Z2 force AT&T from 7.1.1 to Oreo. After updating I had no mobile network so I decided to flash another modem specifically Verizon but now I lost all the baseband the WiFI and mobile data doesn't works and it tells me that the baseband is unknown , i try to flash again the AT & T modem and nothing. Unlock the bootloader a while ago maybe that's useful.
WHAT CAN I DO?
The baseband says unkown because you used Verizon's firmware on an AT&T phone. I did this accidentally last week.
Now, when you said "After updating I had no mobile network" did it not recognize the SIM and have the little warning icon or did it just never connect? For the former, get a new SIM. I had this issue on a samsung with AT&T once. For the latter you might want to check your APN setting here:. https://www.att.com/support/article/wireless/KM1062162/

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
