Hey everyone.
My LG G2X is running Cyogenmod 7.2.
Just last week my phone apparently started to not be able to receive phone calls. I called T-mobile and told them about the issue, however they tried calling me and it went through without an issue.
I am lost for words, i've had people from AT&T and Verizon try to call me and no calls go through.
Any ideas?
Kind Regards,
Jordan
What baseband are you on? If you're on a baseband that is not supported by the ROM then you may need to flash one of these zip files to make your phone capable of making calls. See this thread: http://forum.xda-developers.com/showthread.php?t=1776843

If test calls come through, and calls from other t-mobile phones come through, then it is clearly a t-mobile problem, NOT a phone problem. There is nothing ON your phone that rejects only calls from specific carriers.
You will need to call them back with specific examples of people (phone # and carrier) who cannot call you. Perferably you will also have some examples (landlines, other carriers) who CAN call you.
You also need to make sure to have more than one example, otherwise it could be on the other person's side.
Armed with that information you can prove a pattern and that it is not your phone.
On the other hand, if it is random as far as whether a call comes through or not, then it could be either your phone or t-mobile. A pattern is what you're looking for.
Source of information: I was once a T-Mobile Tier 2 PDA Tech.
Hi All,
I have been trying to get my g flex2 unlocked from sprint for a while now, sprint can only give me a MSL code, so I have been forced to look into other ways to get my phone working on AT&T. I was reading on another thread people were able to get their flex2's unlocked by editing the build.porp, but I have only seen it changed to VZW, has anyone been able to use a sprint g flex 2 on AT&T by using that method. Also I heard that enabling the location services on a g flex2 with an edited build.porp to VZW puts the phone in a bootloop, could you move the GPS files from maybe the at&t model to prevent that from happening, are the gps radios different?
so far i have sms slowly working on tmobile network. i will send an sms but it will crash immediately after i press the send button. strangely enough the sms went through with no confirmation, still playing around with the settings, but have no to little knowledge on editing files or finding out what is going on to cause the phone app to crash.
Just unlocked my phone through the Tmobile app and now plan to root (hopefully I can I'm already on 10D and was gonna do the tot method but idk about all these problems with it, this is my daily but I miss xposed dearly). Any way I want to know will the unlock stick through a factory reset and rooting? Also when I unlocked I got this weird message.....
Update: Well I'm rooted and ran the app again and still shows the message. Tried a few extra sim cars I had lying around for att and Verizon...... BOTH were able to pick able to pick up a signal and read the phone numbers from those cards but of course weren't able to make calls. Are the G5's like the S7's when it comes to unlocking? The S7's support all carriers hardware wise once unlocked not just GSM ones, is this the same? Unfortunately I don't have an active Verizon sim to test with.
Yes I have had the lg v10 on T-Mobile and had it permanently unlocked and since then have flashed wiped and tried new Roms with no revert to being sim locked and I had it done on my lg g5 and since then flashed fluences ROM and wiped a few times and my phone still works when I put my [email protected] work sim in it to make calls and text
I have 2 Note 8s right from Samsung Unlocked. My dad and I are both on AT&T. We both flashed the AT&T firmware. His works with WiFi calling mine doesn't. The only 2 differences are I took an update the day before we flashed and he did not. Also he has had WiFi calling on AT&T with an LG G6 phone and used it. I have never activated any device on WiFI calling with AT&T prior to this. Last night I put my sim in his old LG G6 and called AT&T to swap IMEI numbers. With that phone I was able to activate WIFI calling.
So is the issue really the unlocked note 8s IMEI numbers not set up with AT&T correctly and my dad got lucky or is it with the firmware software?
I have had so much help from BlueFox721 and a few others I know there is an answer out here.
The crappy thing about this is that it is more important for my dad to have WiFi calling than me but now that I know it is not working I don't want to give up!

I hope someone gets it figured out...It would be nice if everything just worked out of the box...
My phone is back to the state it was in out of box I believe. It is telling me Shave an update. I am not sure if the first time it updated it changed something that flashing back to original will not undo. I am contemplating trying to flash the same ATT firmware that I did on my dads or just wait and see what develops over the next few days. I have flashed so many times in the last 24 hours I am not sure what is in my phone
Hello everyone, im new here kept searching everywhere for solution for my problem without any success. In may 10 i bought SM-G955N KT module, it was working great with 2g / 3g / 4g / LTE / LTE+, i went out of usa for almost 3 month and when i came back my phone doesn't work well with tmobile, i can send msgs use lte internet but i cant do calls at some areas, some times i have full lte bar and when i try to make a call it goes to 0 signal bar, i called tmobile many times about the issue but no solution i found out that they did upgrades to their towers in the period i was out of usa from may to august, right now i cant use the phone as any normal person its been a month that i cant use the phone at my house and some areas, i can make calls sometimes if im at different tower locations. Question is, is there any solution for this problem since tmobile did those tower upgrades its screwed up everything..... should move out to att or verizon or what should i do. I really need help with this problem its been a month, any solution would be welcome if it requires root or not i dont care i just want to find a solution for this,
Thank you.
Have you tried resetting your network settings and/or getting a new sim card?
Its not the sim card i already changed it to a new one also i tried it on a iphone 7s plus and it works fine, my phone is bone stock no root no custom software alsi its the korean version when i looked around i found that tmobile did some network upgrades from may to aug and thats when my phone got screwed up, i was albe to play with the ims setting and i got the phone to recive calls but i cant make calls, does my phone screwed up because it has the korean csc and the stock firmware or whats going on here
I'm not quite sure I understand your experience. From what I am reading, you went to Korea, got the G955N (which I bought for both myself and my wife), and then came back to the states and can't get it to work with T-Mobile?
I tried to get mine to work with T-Mobile and have experimented extensively with different CSCs and ROMs.
I eventually went over to AT&T
I've also had a rather extensive experience of how to get 4GLTE working here in the states with AT&T.
Feel free to reply here or DM me if you wish.

Hello thanks for your input, actually i bought the phone in the box brand new from amazon, it came here on may 10 i used it for 7 days 4G LTE 3G works great then i had to go out of country for 3 month i came back at the end of august to find that tmobile did a huge tower upgrades in my area, since i came back i wasnt able to do calls and receive calls, i was only able to text and use LTE internet but not calls, i went to different towers area and i actually was able to make calls but not in every area because some times my signal bar goes down to 0 or even 1 signal and i cant make calls still but my other friends who owns iphones or usa version of android works fine except me. Yesterday i edited the IMS setting im still on stock fw and i enabled every single feature there and i was able to receive calls in my area but still i cant do calls, i wanted to make sure if im gonna follow the steps here in this guide i will be able to use TMOBILE CSC with the korean stock firmware and get the features of tmobile as VOLTE and WIFI CALLING etc with the right CSC for sure and without tripping knox
Thank you
Hi, I did some extensive searching and was not able to find a solution for this.
I've got the SM-G955N, and ran into the same issues as other users in this thread with T-Mobile, has anyone found a workaround to unlock the LTE bands necessary to make the SM-G955N work with T-Mobile?
I didnt find solution yet too, i dont know what to do i gave up i tried everything on the official software no root.

I had a phone with the Korean CSC as well, N phone as well. I left the CSC alone and it worked with T-Mobile and ATT here in the US just fine, last fall.
I later changed the CSC to XXA, and still works well. Just tested it this week with T-Mobile, and it's working. I have to say, that locally, T-Mobile has much poorer spot area service than ATT. Kinda puzzling, but that is the way it is.
My phone is rooted, so it make things a bit more handy to mess about and return to my previous setups.
