[Q] Blocked from AT&T after international travel

I have read through this forum for hours and in no way savvy with this stuff; I have learnt a lot so thank you but please help me.
I just don't know how to tell what the problem is with my phone therefore i don't know which of the 100s of solutions here to apply.
its a S4 i337 previously used on AT&T LTE network, I traveled overseas and used other country's sim card for a short time after giving it to service provider to program. i believe phone was rooted and settings changed for this to happen, though i did not do them or know what they did.
I returned to U.S. and reinserted AT&T sim, made one call, but phone seems to trigger anti theft or network suspend right after. I have had it unlocked twice by AT&T but first use thereafter seems to reblock me out of their network and i get message that this device is blocked from network use. When I call they say phone shows stolen and i repeat process above only to get reblocked again.
I don't know if it is APN settings, previous rooting or what that is causing this? I found an app called SuperSU on the phone, i clicked on its settings and clicked "full unroot" which made app icon disappear but can't tell if I am really unrooted or not. I have also done factory reset and lost everything already, I just want phone to work back on AT&T network as before.

Take it to a best buy Samsung service counter and have them reflash the firmware or update it to MK2. Wipe everything (including internal and external SD card) Then, call att to unblock it again. If it relocks, then go back to the Samsung service counter, tell them the issue and see if they can restore your efs for you from a backup. If they can, do it and then unblock it.
If after all this it relocks, its not your device. Its att who are at fault. Then all you can do is to yell at them.
EDIT:
Another possibility is that the ppl who unlocked your phone overseas stole your imei number and used it to revive a blocked stolen phone. In that case your imei is in an international stolen imei database and you are probably out of luck.

Interesting. If the IMEI was stolen, what would the phone show? Would they clone the IMEI (so it would show the same IMEI) or would it come up as UNKNOWN or blank or something. Reason I am asking is that I've been try to fix an issue with my father-in-law's phone that completely lost the ability to connect to wifi/data after having his S4 "unlocked" in Vietnam to use a local SIM there. Tried may reflashes with MK2 and custom TW ROM's but none work with wifi anymore (data works ok).

If data and calling works then the imei is fine. Its some other issue..

All is speculation but there is a small posibility that when you gave your phone that person gave you another phone which indeed was stolen. Your best bet is to go to the samsung guys right now or learning how to restock your phone. You tube search videos How To Unroot & Unbrick Samsung Galaxy S4

so its been a few days now with no service. it turns out my phone has somehow been programmed with a different imei that comes up as stolen according to at&t. so the theory of my imei having been stolen is pretty possible. every time i have the phone unblocked from the network, one phone call or message causes it to trigger the stolen phone alert and kick me out the at&t network. i have been to the at&t store with my device and the original packaging that shows my original and correct imei but the one that the phone is registering on screen does not match what is on my actual handset sticker and original packaging. the phone never left my sight the entire trip so i am 100% positive my handset was never switched, if anything it was reprogrammed with the stolen imei and they stole mine which is now working fine out there for some crook
i just can't believe that at&t can't verify my original imei that came with the phone i bought from them and just reprogram my phone and get my service going again. its looking like i will need to find a way to recover my imei myself. although i just got the 4.4.2 update that force placed itself on my zero service phone. hope this post helps to alert others to be careful of this type of thing.

Wow! what country did u visit?
If your s4 had insurance I would report the phone as stolen and give the original Imei to be blacklisted and try to get a new phone.

Galaxy Note 4 SM-N910F Invalid SIM

I had been looking at this phone for a while on ebay and despite well... ebay... I had temporary lapse of good judgement and maybe a bit of alcohol and pulled the trigger.
I got the phone thinking it was a SM-N910F, everything I'd read said it would work on US AT&T sans some bands for LTE.
The phone came and it was in good condition. The box and the serial label behind the battery all say SM-N910F.
I turned the phone on, it has a beautiful screen, everything seems to work fine, works with wifi no problems, so far so good.
I turned it off, popped in my ATT SIM and turned back on and, uh oh, got an invalid SIM error.
Ok so next step, I go to the ATT store, they check the IMEI and confirm that yes it will work on their network and they give me a new SIM for good measure. Their new SIM still shows invalid in the phone and the sales guy is confused but then I tell him I got the phone off ebay and he gives me a look of pity. No problem though I wanted the international phone so I could learn about flashing ROMs and such without leaving me with a non-working brick and no communications device.
So I read through XDA posts and various tutorials over the web and try to find out why it's not accepting my SIM.
I flash TWRP, and root the phone, that worked fine.
Then I decide that maybe upgrading the firmware to Lollipop and flashing a new ROM might fix the problem. I go to Sammobile, download N910FXXU1BOB4_N910FOXA1BOB4_DBT because that seemed like a good one that would work. Then try flashing it via ODIN.
ODIN Fails, SECURE_CHECK_FAIL : aboot. Some more reading later I find out that usually happens because you're trying to flash the wrong thing.
So I dig further. I can still get into the stock kitkat software on the phone so I download *Samsung* Phone Info and check out what I've currently got on the phone, but now I'm totally confused because I don't know what to make of it and this is where I need some help.
I've got screenshots but due to being new I can't post a link, I can email them if they'll help.
Settings > Device Info shows SM-N910F with baseband of N910FXXU1ANK4... that looks right
but then I fire up Phone Info and it shows a phone model of SM-N910P which would be a Sprint CDMA phone? and a country CSC of CHN?
so this phone is truly international
European phone, Chinese CSC, with USA Sprint firmware?
Where do I even begin, can anyone suggest what I can do to untangle the mess?

Have you check the box "OEM unlocking" in the developer options menu? This allowed me to use Odin the first time on my tmobile note 4.
If you don't have a developer options menu in your settings, go to about device and press build number 7 times until it tells you you are now a developer.

try a European version BTU from sam i have the same model SM-N910F root is an issue i'm looking at.
as the SM-N910F is Euro i would use that firmware.
Hope it helps.

S7 Edge (SM-G935F Exynos) Carrier Flash ROM Question

Hey guys, i was wondering if i can flash firmware from other carrier without bricking?
I bought my phone last year locked to carrier, and I unlocked it using doctorSIM service. Phone itself works fine, and as I'm not living in country that i bought my phone from originally, phone gives a message "No SIM card installed" sometimes once a week, sometimes several times a day and i need to remove SIM card or to restart phone to make SIM card work again.
Please note:
- SIM Card from my original carrier (from one that I bought my phone from) works PERFECTLY fine
- My other SIM card (that my phone constantly rejects) works in other phones just fine
- I have tried to reset the phone, and carrier bloatware constantly keeps installing
- EDIT: Wi-Fi and 4G are working PERFECTLY fine
What to do? Any ideas?
Thanks in advance and sorry for gramar mistakes

Bump, flashed other carrier firmware, still same problem.

R u rooted? Have you considered flashing a CSC packet for your location?
I have a 930S, and works fine with the Korean ROM/Chinese language here in the US, on ATT service.
I have flashed the ATT, XAA and TMB CSC sets, and though the phone worked, and loaded the correct USA carrier info, I lost the phone code ability, which I could not solve.
In the end I went back to the original Korean ROM and it's CSC packet. Interestingly, though it works perfectly here in the U.S., and I can use/input phone codes, it still shows Chinese cities for my 'Region", none of which I have selected. When I do a search for local towers, it locates and correctly identifies AT&T, T-Mobile, etc. I select ATT. The Chinese cities remain in the region selection, none selected.
Wait and see if someone knows if CSC (Exynos or US based CPU) are interchangeable. I used CSC packets from a universal ROM setup (non-USA).

I'm not rooted, as I use Samsung Pay and have more than one year of warranty left. I will try flashing CSC of the current country I'm in (Austria). Thanks for taking time and writing all this, this problem is unbearable

Hello!
My s7 edge is in trouble, it freezes sometimes, and sometimes it gets a full screen of pixel color flaws, with that problem my root smartphone works two weeks. Sometimes this error occurs in the ROM installation process, I insist on the installation until I can. I tried to install superman rom and due to this problem, the smartphone in the screen of death "exception of bootloader" (But it's already been resolved)...
When searching the internet, I saw that this could have a problem in flash memory.
After all history, I ask;
I could use a twrp file system repair function to try to solve this problem? And how to proceed?
(sorry for the use of google translate)

I am, by far, not educated up on TWRP, so I'm not sure what you mean by "repair", other than making sure your data partition is formatted so it does not cause the issues you are talking about.

Updated Verizon G950U now no service

I have a stock Verizon G950U (on Selectel prepaid but that shouldn't be an issue) and used the PC software to install the latest update NRD90M.G950USQS2BQL1
Immediately following the reboot I have not have service since. My sim works in other phones, took S8 to Selectel store and they confirmed working Sim and said it was a device issue. I have factory reset and even restored the firmware with the software again. I don't get a ton of service in my rural area but was able to activate an old S3 that I had lying around. The Selectel store is also in a larger city with plenty of service.
The radio is on as it shows bars, scans and shows networks, but absolutely will not register manually or automatically.
My limited knowledge and searching says that I cannot directly downgrade the firmware to an older working version. I've rooted older devices but last I played with it KNOX and the risks of bricking are getting ridiculous unless someone can specifically state otherwise for this device and link me to videos and direct download links.
Thanks in advance, I'm pulling my hair out. Short of rooting or waiting for the next update to hopefully fix it I don't know what to do.

Ok so its not a corrupt EFS issue. have you gone into netwrok and switch to global or anything....
Does it show your phone number in the info as well That will tell if its reading sim or not

It does show my number from sim after booting up without a sim and then inserting. I don't see any global settings. Again from the update no settings changed, since then I've wiped to factory settings numerous times.
I can't find a fricken stock rom file anywhere for crying out loud, just loads of register spam sites.
I think I'm downloading an Oreo 8.0 rom but can I downgrade later and again where's the dam file?

Don't worry about Knox, it's not possible to trip it on a 950u

Tried flashing to BQK5 with moderate success. Passed with Odin (which csc file should I use?) but on reboot it stalled at 32% when installing. Rebooted and after flash screen updated android and showed BQK5 but all my data and apps were there so i likely screwed something up. Installed sim card and momentarily showed 4g and appeared to register but at reboot did the same crap with no service.
Called Samsung prior to flashing and no surprise that was a colossal waste of time. I'm not paying them $200+ to fix an unrelated issue with the back glass that cracked with a case on and phone has never been dropped. They did say that they're partnered with best buy but that's two hours of driving for me...I'd fix the back glass myself and try to get them to give me a new phone if it came to it.
Verizon software shows an update now so I'll let it download (again...takes all night for some stupid reason) and vainly let it flash to current version.
I think I found the Oreo 'final' update so might try that...looks like it installs off an sd card if I can find an old one.

How to Full carrier unlock Verizon S8+ with Stock SM-g955u1 bloat free

DISCLAMER: I AM NOT A DEVOLPER AND MAY NOT BE ABLE TO HELP YOU ON YOU DEVICE. UNSUCCESSFUL ATTEMPTS TO FLASH FIRMWARE ON THIS DEVICE CAN AND WILL BRICK YOUR PHONE. BACK UP EVERYTHING IN EVRY CONCIEVABLE WAY.
After days of trying to do this with all the outdated guides and miscommunications and edits in post i decided to try and make a streamlined guide to help others.
NOTE: If your are looking for anything else other than a stock bloat free unlocked firmware then look elsewhere.
Also if you are using rev 1 booloader then this will ireversablly upgrade you to rev 2 bootloader not a real problem just a note
Download 3B's patched Odin 3.13 https://drive.google.com/file/d/17wH1YHcGsOCxbDGYDoy9VlnqO_Xi6IOm/view?usp=drivesdk
Download samfirm.exe
https://drive.google.com/file/d/1XdboeTqk8pSZyJQVt-IHVHFfznJ9eOQk/view?usp=drivesdk
Thanks to @zxz0O0
If you can't find your own drivers don't do this
1. Extract B3 Odin
2. Extract and run samfirm.exe
3. Make sure auto is checked use SM-G955u1 as model number and XAA as country code then search. It should find you the absolute latest firmware
Hit download and choose file destination. This can take a while.
4. extract firmware.zip
5. Run 3B's Odin and add file to there respective locations. I.e. Ap file in Ap slot etc. Use the non home CDC
6. The only thing you need ticked in Odin are already set by default
7. Boot phone into download mode power+bixby+volume down while the device is off
8. Read the screen that pops up very carefully and decide to continue at you own risk by pressing volume up
9. Connect phone via USB 2.0 port do not use a USB 3.0 port it will not work
Make sure Odin recognizes device if it doesn't then u have a driver issue
10. Press start and wait patiently
11. Phone will reboot it self setup device and insert sim card. You will probably get a notification say phone not allowed a quick call to the service provider you trying to use is all that's in order here
12. Enjoy your carrier unlocked stock SM-G955u1 on your preferred network
I AM NOT RESPOSIBLE FOR ANYTHING YOU DO TO YOUR OWN DEVICE YOU WERE WARNED.

So this gets rid of all bloatware?
From my knowledge, Verizon does not, and has not ever carrier locked their phones. Seems like a lot of trouble just to debloat.. Am I missing something here?

Any idea why it stucks at "SetupConnection.."

This worked GREAT! My Verizon S8+was working fine on AT&T before I did this, but I was stuck on Android 7.0. So thank you so much for this. There's only one thing that bothers me is in my drop down menu there's a notification that says "Sprint OMADM Checking Device Status." Which really isn't a big deal, it's just annoying. Another thing I worry about is, i'm using it on a GSM network, is it actively searching for a CDMA network at the same time and draining my battery? Any input would be appreciated, and thank you again!

The method will be similar just need the proper firmwares for your device

This being quite an old post I was wondering ...
I am currently on G950USQS5CSB1 with CSC XAS/XAA/VZW.
Currently I have no carrier bloat (good), I am on Mint with no issues (good) and I get prompt OTA's I assume for carrier VZW but I lack wifi calling which I would like (bad).
I have downloaded G950U1UES5CSB2 for G950U1
Will this work using the 3B modded Odin as described without having to flash the combination files?
normal and Prince Comsy Odin both failed.
Thanks
edit: Took the dive .... worked great thanks, now on G950U1 and have wifi calling and VoLTE

This is great, minus one thing, it installed facebook on my phone, which I didn't have before and never wanted and it won't let me uninstall it..

I'm hoping you are still monitoring this old thread. I have a Verizon Galaxy S8 and followed your instructions exactly (except that I downloaded the files for SM-G950U1 (my current model is SM-G950U). When I start Odin, it gets stuck at "SetupConnection" and never goes any further. Thoughts?

Yea. I just switched to Verizon. You should be able to just pop your sim in and it automatically carrier switch. Most of these are multi carrier

Yes, it has unlocked as it recognizes my sim card and carrier. But no signal. I think the problem is the device is with "MIPI device fail" status

Yea not yet. I'm also on 7. We need edl files first. I got the combination rom for the boot img but edl is still missing. I got a few guys looking for it. I typed in the error you gave me and saw a few sites with no box fixes. Normally if you can get to the menu I don't see root being needed. But I may ne wrong since I've never seen this error

This would be great if it worked. However I have my doubts. You would first need to have the phone be from Verizon or be on another carrier and *unlocked* first before changing any CSC using the US OPEN firmware which allows you to simply put a sim card in and switch carriers by swapping sims and letting Samsung reconfigure the phone. The BEST setup is a SPRINT phone.. unlocked.. then converting to U / U1 firmware. You then have every possibility when it comes to carriers sitting at your finger tips!
Good Luck

Your post dont even make sense. The Verizon s8 at the time came sim unlocked. All you had to do was swap the csc. But worked unlocked out of the box. Why would a sprint device be the best setup. All the us s8s are identical. Sounds like you come from LG which is true on devices and versatility. Not Samsung.
