I nucked up BIG time.
I had xxuamdk 4.2.2 i somehow* managed to upgrade from kies. now i have xxuemj8 4.3 BUT no network connection my imei has not changed at all. I tried upgrading radio via odin but no luck lots of radios didn't even worked. workking ones cannot registered on network. i tried installing other roms and no luck.
BUT something is fishy in here. when my phone says not registered on network. i tried calling myself from land line i got ring tone. but there isnt any action om my galaxy. when i turn on airplane mode i got carriers unreachable message.

i had this happen to my cspire phone today. It wont get past activation right?? Mine would try to activate on first one and go to different carrier like verizon, 2nd one just wouldnt activate at all. It acts like the modem is wrong but the sim card app's will tell you that its fully functional as does the settings menu, its just stuck in ROAMING mode.. I went through 2 of them this morning, My 2nd would keep trying to activate and then say no sim and crash out, so odin it back to samsung official status and go claim your warranty and don't touch it again. I did both with the knox 0x1 and far as i know that doesn't hold anything against your hardware warranty. Company should approve it as long as you have their original software back on there in the locked state.

thanks for your advice dude but i couldn't care less about warranty i have friend work in there but i dont have time to go there and i cant be away my phone for my job for more than 1 hour. even right now i have wifi hot spot to use my phone. i have to fix it or i will have to buy a new one.

OK try this.
Flash a custom recovery, Philz is my recommendation.
Boot to recovery (hold volume up +power)
Them in recovery menu go to mounts and storage and format System, cache, data, pre load.
Now flash stock ROM again and keep fingers crossed.

Just telling you man the carrier couldnt even fix mine with their forced data fix from their system. The phone gets screwed up and not even odin can bring it back. You can get someone to pull your modem from their rom and try to flash over but it will fail. Once its there its like it cant untake it. I returned 2 by warranty today, im done with messing with this pos phone if thats all its going to do for me. But go in the store tell them the sim card went bad, they will piddle with it and try another card and it will do same crap, then they will finally break down and offer u a warranty phone. Mine were FREE!! You said you cant be away from the phone for more than 1 hour, well at this rate NOTHING is coming through your device at this point?? So your hotspot does nothing if the phone doesn't have a data connection? Mine would get stuck with the roaming triangle, you could do 611 and hang up and 4g would come on but then go away again. If thats the case you'd save time and hassle by just taking it in with official a odin full restore flash on it.

[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.
Android version 4.2.2

please help me… i am not sure if i need to reroot, delete binary counter, flash with files???? i have read some about odin files, don't know what is the latest and which sources are safe…just confused all around.

please someone tell me where to start
please tell me where to start? do i need safestrap?

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.

[Q] Roaming, cannot register on network

Hey,
I flashed my device some time ago and I broke the glass. I sent to a repair shop and since then I'm stuck on roaming and I can't register to my network (Videotron).
When I use auto connect, it uses Videotron PRTNR which is videotron's partner network (rogers).
I want to install the stock firmware but I've tried to install about 7 of them from sammobile or samsung-updates, all of them show BMC (BELL) or EUR at the end of the firmware version in kies.
Kies refuses to let me install the stock firmware from the firmware upgrade and initialization it says "This version of the device cannot be updated."
I want to be absolutely sure it's not my firmware that's causing the problem before accusing the repair shop....
Does anybody have any idea?

The way you worded your post is confusing. Did the glass shop break your phone or did your flashing cause the issue? We need to know exactly what you did and a lot more information about your phone configuration if you want good advice. You didn't even tell us which S5 variant you have, the specific firmware versions you refer to or give us a verbatim log of what Odin said when you tried to install (an unspecified) firmware version. All of which are critical details.
Some obvious first steps, try your SIM in another unlocked phone to confirm that the SIM and your account are working properly. Also try a friend's SIM in your phone and see what the result is. Check your phone settings for inadvertent changes of course. And list what your phone settings are for us! Clear your system cache from recovery mode.
If you still have problems, try writing a stock firmware with Odin, followed by a factory data reset. Then give us a detailed, step by step description of what you tried and the results for a start.

My apologies for the lack of information
I have the SM-G900W8 model, using Videotron as my network provider. I believe the roaming issue did not exist before the repair, but they won't believe me since I have a custom rom installed.
While my phone was being repair I've used a galaxy S3 and it started roaming... I thought it was normal since the phone is from Bell (Unlocked) and maybe the network aren't compatible.
I tried what you suggested and inserted my Sim card into my girlfriend's Videotron Galaxy S3 and it still says roaming. I guess the problem must be with the sim card or videotron's network?
And about the roms I tried on my S5 :
=> with Phoenix rom v2, the problem is there.
=> With a couple of original SM-G900W8 stock rom (found on sammobile website) flashed with odin , the problem is still there.
I did try to clear the cache etc...

I forgot, the latest rom I flashed is named G900W8VLU1ANF4_G900W8OYA1ANF4_G900W8VLU1ANF4_HOME.tar.md5.
Please let me know if I forgot something :fingers-crossed:

fffft said:
Critical point that. If I understand your reply, the problem remains when you try your SIM in your girlfriend's phone. That shows the problem to be independent of your phone i.e. it is a problem with your SIM or more likely, account. Especially if your girlfriend doesn't have this issue with her own SIM.
Talk to your carrier's support department and if they can't resolve it immediately, open a ticket for them to look into it further. Based on what you described it doesn't seem to have anything to do with the glass repair people. It's just an account problem that happened to occur while your glass was being repaired.
Let us know what support says or if anything changes. If you're ambitious, post your network settings here for review, just in case they impact on the issue in some way. Still it seems to be an account issue.

I am also with Videotron.
Try to use the Search for Network, not the auto connect and see if Videotron is available from that menu.
If it is not, be sure that there is a Videotron cell tower near you otherwise it will default to Videotron PRTNR which is the normal behavior if the Videotron signal is out of reach.

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 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.

Unlocked Samsung S8 to Xfinity Mobile

I recently switched to Xfinity mobile from AT&T. I got the cheap Moto phone for basically free but would like to use my GS 8 factory unlocked.
When I put in the SIM Card my GS8 is unable to connect to the network.
I recently tried rooting my device and that failure resulted in a warranty claim. Now that I have it back I need assistance... Don't want to spend the money on a new phone as my GS8 works just fine.
Saw a recommendation to flash my device to Xfinity firmware but not sure about this approach given my recent root failure.
Anyone ever BYOD to Xfinity and had to work around the network issues?

I'm a complete noob, but you say your s8 is unlocked so have you tried to change the apn settings for Xfinity mobile

Typically, it's very hard to "brick" a device. As long as you are able to boot your device in upload mode, it's not technically bricked. Most flashing errors can be fixed by booting the phone into upload mode and flashing stock (the original baseband file of the device) firmware in Odin.
I personally think you should be fine using an unlocked phone on Xfinity Mobile (even though it's not technically supported). When you flash in Odin make sure the CSC file is from Xfinity Mobile. Try doing some research in the Carrier Switch thread first.

I personally think you should be fine using an unlocked phone on Xfinity Mobile (even though it's not technically supported). When you flash in Odin make sure the CSC file is from Xfinity Mobile. Try doing some research in the Carrier Switch thread first.

You mean download mode. Upload only is bricked

I recently switched to Xfinity mobile from AT&T. I got the cheap Moto phone for basically free but would like to use my GS 8 factory unlocked.
When I put in the SIM Card my GS8 is unable to connect to the network.
I recently tried rooting my device and that failure resulted in a warranty claim. Now that I have it back I need assistance... Don't want to spend the money on a new phone as my GS8 works just fine.
Saw a recommendation to flash my device to Xfinity firmware but not sure about this approach given my recent root failure.
Anyone ever BYOD to Xfinity and had to work around the network issues?

First off welcome to XDA Im pretty sure I saw you post on the XFIN forums..
Yea I have never seen that issue I have used several byod devices on XFIN all where verizon based though..Which does not matter on s8 as it is a multi carrier device
So first you need to see which firmware you are currently running
Download that exact same firmeware with cct as csc which is what determines carrier Heck if your on tonight I can upload a CCT csc and you should be able to flash one in ODIN if yours is the 950u1 which is unlocked s8 model We will be changing it to a regular 950u which is carrier....
I am Like the local Xfinity guru here as I use them I have mine rooted and everything even bricked several to previous said upload mode But I was playing with deep deep stuff.Nothng that odin can really harm
