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.
*there is stupidity. i still cannot believe myself WHY I DID IT. I didn't even back up my efs.

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.

NO service plz help

i have one nexus 4 purchased from Ebay. it has
4.4.2 OS STOCK,
base band M9615A-CEFWMAZM-2.0.1700.97
KERNEL 3.4.0-perf-g2cae413 WED nov 20 14:54:28 PST 2013
build number KOT49H
it has unlocked bootloader, rooted, twrp installed.
it is able to show me IMEI number in about phone and as well as on dialer *#06#
now the problem is, when i insert sim card, it show me no service and no signal in status bar.
so not able to use phone.
kindly help me

Flash the latest factory image.
My N7's baseband version is M9615A-CEFWMAZM-2.0.1700.98, so I think you have the 4.3 baseband which is incompatible with the 4.4 roms, that's why you don't get service.

Best solution is try some another "micro sim".
DONT cut it but bring it from your service provider.

From what I know I believe the sim cards can have hardware within 1/16th of an inch from the side, or it might have been 1/8th but yes dont cut the card, um I know it sucks but back up what you can with something like titanium backup, then try undoing what could be the cause, so flash stock rom. With titanium backup you just hit backup/restore then the checkmark in the top right then scroll way down and hit restore apps/missing apps+sys data... if it fixes the problem then great but put a copy of the backup on your computer in case the extsdcard gets wiped too for some reason or in case you have to send it in

i use following method to downgrade
http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312

Ill ponder for a while and see if I can brainstorm a solution, ill ask around a bit and see what I come up with,
If your worried about your warranty and your carrier won't help you, I suggest going to best buy and letting the Samsung guys take a crack at it, they have the proper software to find the problem.

OK when you first got the phone was the sim working?
Is it a carrier specific device?
If yes are you using a sim card from that carrier?
Is the phone unlocked or factory unlocked or is it locked?
Was there any thing you did such as flashing custom roms?
I think it may have a bad Imei but I'm still trying to figure that out

dont know if you ever got your issue fixed or not, i had a similar problem the other day on my galaxy s4 i337
i was able to make phone calls and recieve text messages but i could not access the internet through the network, my carrier actually did something that helped but didnt fix it... the technical support team had me turn off the phone and then they erased me from the network, so when i turned the phone back on the phone rebuilt the network through the sim card and for some reason i have better reception now...
i still could not connect to the internet via wifi or mobile network so i factory wiped and installed the stock firmware.
do you have somewhere to go where they can "officially" flash the stock firmware? here in the usa i can take my phone to BestBuy, a large electronics dealer, and they have a samsung area that the people have the tools to do so.
maybe your network carrier can help you, maybe its not a phone issue but rather a network provider issue.

It's a little bit strange but you can try to use an adhesive tape on the side of sim card to prevent a short circuit between contacts and the sim card's metalic tray.
It worked for me.

Samsung Note 3 doesn't want to recognize/register my SIM

I'm not a 100% sure how this problem occurred, I believe it was after flashing an S5 custom rom called: "RC Elite S5 Port V16" To my Samsung Galaxy Note 3 (N900W8). From what I was reading it was a ROM that "converts" your note 3 to a note 4 or s5, while still having all the Note 3 features. Another possible cause is trying to use RegionLock Away.apk by Chainfire to essentially(unlock) the phone. I feel like this is the main cause though as this affects the modem on the phone. This isn't the SIM as I tried it in another phone and works fine with calls and texts.
My phone doesn't want to register its mobile network anymore. When I try to make a call or text it says:
"Not Registered on network"
I was reading online for about 2-3days now for possible solutions that can cure this. Such as:
1. Going into Mobile Networks settings and manually register [failed, details below]
2. Going into Mobile Networks settings, hold home button for 2seconds and then hold power button + home button for 15seconds [failed, details below]
3. Taking out battery while the phone is on and remove the SIM card, clean it and re-insert [failed]
4. Factory Reset [Failed]
5. Wipe Storage and re-flash stock ROM [Failed]
Options 1 & 2 do not work because when I try to access Mobile Network Settings I get this:
"Insert SIM card to access network services"
The SIM card is inside the phone though...
So what I did is found a mobile network options shortcut "program" from GooglePlay Store and installed it. It allows me to access the menu, which is great! Now, when I try to register the SIM card to my correct service provider (BELL CANADA)...it will make me wait for about 1-2minutes before I get "Unable to register, try later" error.
I tried the factory restore with a stock 4.4.2 ROM from Sammobile and the issue is still there.
Is there anything that anyone knows that can help me resolve this problem? I tried EVERYTHING i can possibly find on Google. I've seen posts of people suggesting to flash a modem.bin file with Odin but I don't know where to get those files, nor what to look for in terms of modem file "types".

I tried region unlocking it with RegionLock Away by Chainfire. I would like to say afterwards this issue occurred but as far as im concerned, using a TELUS Mobility sim card activates the network pin unlock. So i'll be going with no, it's not unlocked.
I currently have a Bell LTE 4G SIM card installed on the phone. If you check the photos there it shows I have a full connection but unable to make calls nor access the mobile networks menu.... =/

Do one thing.
1. Turn off the phone. Take a out the simcard and battery for some min.
2. Add the battery only. Turn on the phone and factory reset your device (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Insert SIMCARD without turn off the phone.

They there! I tried to follow all the steps to the best of my ability but it seemed that didn't work. For 1, the note 3's sim card slot is blocked by the battery so i can't take it out without turning it off. In addition, after only inserting the battery and performing the factory reset, I decided to test it and the issue is STILL there even though a sim card isn't even inserted AFTER the factory reset. Same error messages as if nothing ever happened, even shows full bar reception even though nothing is in there. =/
This is the most unique problem I have ever encountered myself. I really don't know what to say...

Bumping.
After some more research I was wondering if you reflash the stock firmware back, does it effect the EFS partition at all? Cause if it doesn't I believe I installed a faulty EFS partition accidentally which results in the broken connection.
Any way I can get a backup of an EFS file that I can flash?
Thanks.

Bump. This issue is driving me nuts.
Thank you in advance.

Thanks in advance for the replies.

I had this same problem earlier (for a note 2) in the week where it just wont register any sim card.
In my case i think the problem was that i did a full format before flashing which probably deleted the EFS folder.
I tried so many options and eventually managed to resolve it by following the following instructions to restore the stock firmware.

Hey there!
Thanks for your swift reply! I had already did the Samsung Recovery via Kies 3. Do you know if I reflash it that way that the EFS folder would get flashed as well? Because after doing those steps the issue is still there, after about 3 firmware recovery flashes. xD
I didn't even think about backing up the stupid EFS folder otherwise I would have. I was looking at this

Is this the same one? xD

SIM card not detected

I moved my T-Mobile SIM card from my Nexus 6 to my never used, eBay purchase, 6p. The 6p does not detect the SIM card. I reinserted it multiple times with no luck. I don't know if it matters that I installed TWRP, Nitrogen ROM and Franco kernel, without the SIM in the phone?
The phone is otherwise fully functional.
Any ideas on what might be going wrong? The package slip that came with the 6p states, "Tested for Key Functions, Ready for Resale". I've contacted the seller for advice.

Probably should of checked it out before loading a custom ROM. That being said if the ROM is 8.0 I don't think the first version of the update is compatible with T-Mobile.
"8.0.0 (OPR6.170623.013, Aug 2017, Not for TMO/USCC/Fi)"
You should maybe try a stock ROM first. Get nexus root kit. There is an option to revert the phone back to stock. Might help.
Just a shot in the dark. May also be locked to a region. Good luck though.

I reinstalled stock Oreo. Now, I'm only seeing "No Service". I don't know if this is of significance, but when I check Settings - > System - > About phone - > Status, SIM status everything is blank. At least the SIM was detected. I didn't realize when I installed stock Oreo it would wipe out my SDcard.
The vendor image is used with Nitrogen was opr5.170623.007.img.

And I suppose the sim works in other phones?
It's hard to say what is going on. May just be in backwards?
Aside from the bootloop and battery issues the 6p has been awesome as far as loading ROMs. You never have to replace the bootloader so even if you break the recovery it can be fixed easily. Not the same for my sapphire unfortunately.
Anyways I would first say it may be a physical issue, Especially if the sim says it's blank. Again, good luck.

I believe it's just Android 8 and not the phone. Go through any 6p Oreo thread and will find one person with this problem. Solutions that where posted fingerprint/pincode security off before flashing, no encryption on first boot and solution that worked for me complete wipe of phone flashing stock Oreo. I haven't heard any direct answer on what the cause is and I think the first 2 solutions worked for people because they did a clean flash of stock Android 8 anyways.

Yes, the SIM works fine in my Nexus 6. I noticed under SIM status, it lists "No signal".
I installed the factory Nougat ROM and still no service.
Under SIM status in Settings, Network is Unknown, Signal strength is 0, Cellular network type is Unknown and Service state is Out of Service.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?
Put a known working SIM in the phone from a different carrier (preferrably not an MVNO), If that doesn't work, since your phone is new (to you) there is no harm in fastboot formatting these 3 partitions (system, cache and userdata) and then using the Google script (batch file) that comes with a full factory image. Not a factory reset, not manually flashing a ROM. One other possible scenario is that if the phone was previously used on ProjectFi, you may need to contact Google and have your phone's IMEI de-registered. Hopefully you get it working and won't be forced to return the phone.

Is your IMEI field blank too in Settings? If the phone does not have an IMEI, the device may have corrupted EFS partition(s). Boot the device to bootloader (fastboot mode) and select "Barcodes". Is your IMEI there? Is your model a H1511 (US model)?

Barcodes shows IMEI present and model is H1511. I ran the script in the full factory image for Oreo and then tried the same with Nougat. I didn't reformat the partitions prior to flashing ROM. Is this important or does the factory image replace them anyways?
I don't have access to another carriers SIM card.

The script uses fastboot erase which does not format the partitions. Formatting returns partition information, any errors and in some cases corrections. You did not mention IMEI within settings, both under "SIM Status" and "IMEI information". If present in bootloader, but not in settings, this may further point to a SIM card. Until you try (borrow) another carrier's SIM for 5 minutes you won't know for sure. At the very least you could get TMo to provision you new SIM. They should not charge you for this, and it may change your situation. There are many threads on this very same topic. Maybe searching those would give you another idea.

According to Google, the phone was purchased from them. They do not know if the phone is financed, as this would cause the IMEI to be locked. I'll try the T-Mobile store next.
Spent an hour at T-Mobile. The sales rep was determined to fix it, but in the end was unsuccessful. The Ebay seller issued an RMA and I dropped off at the P.O.. Will try getting another.

No, I meant the the Google-Fi the MVNO (carrier) not finance. If the phone was activated on Fi, it will have to be de-registered on their end. You still did not reply about IMEI present or not in Settings>>Sim info?

When I went into Settings, the IMEI was present, but no carrier information. The phone recognized the SIM card, but that was all.
In the chat session with Google Support, I did ask about Google-Fi and she wrote that she was unable to provide any information on that. She said the only information she could provide is where the phone was purchased.

I came across the same issue. Just flash your vendor.img using flashfire, this will fix everything.

Another fix for the no sim is too turn off security pin lock and reboot the phone. I take no credit for this find just spreading the good word. ?

Thanks so much. Worked like a charm and could then reenable pin lock and reboot and SIM kept working.

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!

I have a verizon s8 plus does this still work please confirm???

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?

Did you by chance boot download mode?

Will this work if I have a v5 bootloader?

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
But yea I don't know about the firmware program he's offering never used it I get mi e from sammobile.com or update.com

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

Never saw that one before. But theres a few fixes supposedly

You'll have to root and do a nv rebuild it looks like
Need access to hidden menus

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.
