Hello so I have recently purchased a Samsung galaxy Note 5 Verizon model. Since Verizon doesn't lock there devices I decided to use it on AT&T so I just stuck my AT&T sim card into the phone it worked I had to tweek some APN settings but nothing extreme. I noticed that I was only getting "H" and "H+" data so i double checked and yes I can get data on some bands from AT&T I had then done some research and could not find any guides that helped me so I thought id post my questions here to see if I could get you wonderful people on here to help me with my problem.
Problem 1: It does not let me enter MMI codes it give he the "Connection problem or invalid MMI code." message (this is what it looks like: XDA doesn't let me post pics so....PM me for the links i guess.)
Problem 2: I can only get H or H+ data and I know this phone cant get AT LEAST 4gLTE bands from AT&T is there anyway I can force it to use 4gLTE and nothing else?
Rest of the pics that could help troubleshoot.
Since XDA doesn't want me to post pics in order to help me I guess PM me or email me and ill send you the image links?

It's hard to say without knowing exactly what he did to it.
computers are complicated and a tablet is basicly a computer with a phone in it. he could have messed up a modual and decided to get out from under it. because once you start rooting and putting whatever you want on it, it's basicly yours and your warrenty is over. best way is to restore it back to the factory version and start over from there. this way you can tell if it's a software problem or hardware. it's just like building and modding your own computer.
Hi All,
Recently purchased a Samsung Galaxy S2 from Gumtree online. It was only working on o2 network so got at unblocked from a guy at a market stall so that it works on all network sims. It was working fine for about a week but then randomly came up with a message saying "emergency calls only" and I coulnt make or recieve calls or texts even if i changed the sim to o2. The internet was still functioning correctly however.
Called network provider and have been told that there is a bar on it by an insurance company. Tried to get back to the seller but have not been able to contact him. Have reported him but I would just like to know is there any way to unblock this phone at all? Dont want to lose out on all the money spent on it. would it be worth downloading any unblocking applications if the phone has a bar on it?
Please any ideas, comments and suggestions would be greatly appreciated.
Apologies for the long message
Thanks
this section is for i9000 Galaxy S, not Galaxy S II, pay more attention please because here maybe we can't help you
Unlock the phone and flash to a generic firmware.
And please post in the correct sections to get help better.
im using my SGN4 in a brazilian carrier, and everything was working perfectly till from nowhere the phone lost connection from network.
I was unable to make phone calls , but strangely my 4g connection was on i could browse on the web normally. How this is possible? I popped out the sim card and tried in another phone, it worked normally. I also tried another carrier on SGN4, i was ok too. Anyone have an idea what is going on?
factory reset, problem persists, i have data connection, but cant make phone calls.
Is the phone unlocked. Yes I have to ask.
BAD ASS NOTE 4
Yes it is as I told I was using it with my Brazilian SIM card
Is their anyway to check if it still unlocked. I know some people said when they unlocked it was a temp unlock. Did you check APN to make sure they set right for that carrier
BAD ASS NOTE 4
hey guys, im back to this post because the problem persists.
Here is the scenario:
I bought the phone from a Swappa Seller. Phone is t-mobile branded and was in the box, Brand new.
http://swappa.com/listing/ZPB505/view
Brand New Samsung Galaxy Note 4 SM-N910T White ( UNLOCKED) 32GB
Phone is brand new in its original box. The phone has never been used. All Accessories are still sealed in plastic - The phone model is SM-N910T. This is a great deal on a BRAND new - NEVER USED phone!
This phone is guaranteed to work with AT&T. There is no regional lock whatsoever

Can anybody tell me why a T-mobile unlocked phone won't work with T-mobile?
I used the phone on my carrier and it was flawless. Everything was fine till suddenly i lost phone signal. It always show "NO SERVICE" message now, but strangely I still have 4G Connection. I can use the phone to navigate, not to make phone calls.
So I swapped carriers, and the phone was working ok, phone calls, data connection.... then the thing happened again: no service, but i have 4g LTE connection.
Inserted a third sim card, from another carrier. Phone is fine, workin as it should! But this is not my main sim card and i would like it very much to work with ANY carrier. Do you guys have any idea what the problem is? Factory reset did not work at all. For the others sim cards, it recognize the network for a second and then "no service". How can i have data connection if there is "no service"?
Im really desperate because i payed a lot for this note 4... Maybe if i root the phone and flash another ROM?
help please!
Is that possible that previous owner reported is lost and now imei is blocked? Your carrier may participate in that program.

thank you im going to check with my carrier.
* BUMP *
Sorry to revive this old thread, but has anybody figured this out?
I too have data with No Service (no voice) when roaming to the USA from Mexico (Telcel). My Note 4 was purchased on T-Mobile USA (contract free) but got it unlocked by gsmunlockers.
Everything was perfect until I got my Note 4 upgraded to 5.1.1 rooted. I have tried several other ROMS and Basebands with no avail.
Any ideas?
Cheers!
Sorry if this has already been posted, I try to search as much as possible before making a new thread.
New N910T owner here, upgraded from N900T but got it second-hand from someone who I assume used JTAG to repair the IMEI. Haven't been able to get LTE at all, no matter what ROM I'm using. (CM based ROMs display H/H+, TW based ROMs display 4G) I odin'd by using the latest NK4 full firmware (found here) and still no avail.
I don't have an old sim card so I ruled that out. I used it with my old N900T and it gets LTE here no problem. For some reason this phone just will NOT connect to LTE. Trying to find a network will lead to a 5-15 minute search eventually leading to "No service."
Attached is a picture of the ServiceMode menu. Not sure what other screenshots or information I need but I'd be willing to provide anything if it can help diagnose my problem. (If it IS a JTAG issue I'm screwed, the person who I got the phone from was shady to begin with, couldn't say no to such a low priced Note 4 though.)
Currently running NK4 on Hyperdrive ROM RLS3 with stock kernel.
Fixed by going into *#0808#, selecting DM + MODEM + ADB and then used QPST/QXDM to fix the target port.
same issue
I was wondering if any fixed the issue, I'm getting the same issue..
Can you be more detailed?
I'm having the same issues a ls the first post diacribes. I bought a phone finding out the one I number was changed, well the phone register but I have issues connecting to the network, and I can't connect to the 4G lte. The second post states that something need to updated but no instructions.

That doesn't work for my phone, had tried it and no go.
I was wondering how you fix your phone port just like in post 2
I know this is an old post, but did you ever get it resolve?
Hi member Ohmygaa. Accidentally I found your post here and I found it very interesting since I have exactly the same problems with my note 4 tmobile sm-n910t as you described. My phone which I bought on ebay shows no lte only 4g doesn't matter what rom I'm using. Even though Internet shows 4g but it works very slow, can't practically download anything, even websites don't work. Searching for signal every 20 minutes so I'm practically unable to use it. The imei *#06# is different than that on the sticker under battery. So my question is could you be more specific with this fixing of target port ,please? I could try your method maybe it would help to fix my phone? Best regards from NY
Hello,
I bought a SM-N960F/DS off of ebay from seller never-msrp
I followed the guide on here to root the phone, and then followed the guide here to add features for my carrier (AT&T):
tekhd detonator (I can't link it because it is an outside link, and I don't have enough posts.
The only thing it seems I am missing now is call waiting. When I try to access the call settings I get an option that says:
failed to read data
Something went wrong. Check your sim card or network connection, then try again
And the call waiting button is greyed out so I can't make any changes to it.
I searched for call waiting on threads here, but I couldn't find anything. Any help is appreciated.
figured it out
I added my old iPhone IMEI to my account and I was able to toggle the call waiting switch to on
Glad you got it sorted! Enjoy your Note 9!

Did you try using the IMEI number of your N960F?
I did not, because the guide for detonator mentioned that you had to give AT&T an AT&T branded IMEI for wifi calling to work
