Hi,
The first thing would be to check your CSC and modem firmware. Use Phone INFO ★Samsung★ app to get all major info about the phone. It is important to know when you are going to flash another stock firmware.
I had issues last week with data and it was caused by bad CSC/modem. Flashed everything back to stock with official firmwares from SamMobile and it fixed my issues. After that, I was able to flash my custom ROM and everything is smooth sailing since then.
Let me know if you require more help.

Thanks for help bro. I took a screen shot of my info. I'm not sure why it shows bmc when I downloaded the rwc files. And is the product code correct?, also I never seen the code for csc modem before. Is it not suppose to match baseband, pda, bootloader

Everything is good, you're almost there.
You have the right firmware but now you need to fix your CSC. The stock ROM is multi CSC so Rogers (RWC) is already installed but it chooses Bell (BMC) by default. What you can try :
- Power off your phone
- Remove SIM card and power on (your phone will start and say : no sim card)
- Power off and wait a moment
- Insert your Rogers SIM card and power on your phone in Recovery Mode (Volume Up, Home and Power on boot). If you have:
#manual mode#
--appling multi-csc...
applied the csc code : RWC
successfully applied multi-csc
That means that your CSC has been changed to Rogers. Problem should be fixed.
If not, the app you downloaded contains a CSC Changer but it will wipe your data. Make sure to have backups beforehand.
Let me know if you need anything else.

Thanks for all the help man, did the sim thing and it just loaded me into twrp and i didnt see an option so I changed it via the app. Same thing still got the 4G and bell bloat. But csc now says bmc/rwc

Ok. Try this now :
You must dial the following key sequence to bring up a regional carrier menu: *#272*[IMEI]# (that is *#272* (your IMEI number) #) - You'll find your IMEI in the Phone Info app.
When the menu comes up, select the regional code for Rogers RWC. The phone will now go through a reset/boot sequence and come this time, it should read the APN settings from your SIM card and viola, you now have LTE. If you do not see LTE but 3G, you will need to ensure your APN settings are correct and then go into the Network Mode and ensure you have LTE/WCDMA/GSM (auto mode) selected.
Let me know how it goes.

I actually did the last sstep you mentioned below this morning (found the steps online ) and it still didn't work lol, so technically when i did it in the app it was my second time restarting the phone.Not sure what's going wrong here. Seems like bmc still lingers around. Haha don't give up on me

Don't worry, I'm not giving up on you
When you flashed back to stock ROM, did you do a full wipe before?
It is really important that you do a full wipe so that it doesn't leave any traces of your old installs.
Try to flash via Odin (while your phone is on Download Mode). Check the AP and the CSC box and input the stock file from SamMobile.
Let me know if it fixes it.

Make sure to backup and then erase the two modem data partitions as well. You can find the fastboot commands in the XML of the firmware packages.
Without behaviour might be not what you are looking for...

I worked for me thanks

Modem file for dual sim
Can anyone please share modem file for dual sim model as I've accidentally selected radio band as USA and hence won't get the network in sim slot 1. Also, if possible, please share link to a step by step tutorial as I'm a novice. Also plz tell me if flashing is possible without using a pc and will the warranty of the phone get void. A prompt response will be highly appreciated.
Thanks

I think Flashify can flash without an external device BUT having the OS (Android) running with all the options for locks and alarms would scare me.
I do _think_ that flashing original Motorola signed binaries will not void anything, to be more precise: With a locked bootloader such procedure should be impossible.
Before you flash a baseband (modem; for which we'd need your current version - see "my phone"), I would recommend just erasing modem setttings. I suspect this is where the modem config is permanently stored so erasing it should set this to default.
fastboot erase modemst1
fastboot erase modemst2
I would assume that after you boot, your device crashes once - so it does for me after flashing the modem. Happens when I make the first call. So just try calling your mailbox or something.
Again, I can't and I won't gurantee anything. You warranty is void!

Here's the version of baseband my phone has got.
tinypic.com/r/2ntb49c/9

I strongly suggest you try the fix above before going after this. This reflashes your modem which might be unnecessary.
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
The modem files are in the download, the ones you are looking for are in:

Thanks a lot, erasing the modems did it for me.
Many thanks mate.

Great. You can hit the "Thanks" button if you appreciate it.

I could fix my phone by erasing modems, after doing that I performed a factory reset, but now I've another problem. Installing apk files takes longer time than it would take earlier, does it have to do anything with the problem I was facing earlier?

That does not make sense - it just takes longer on the Moto X; I've experienced the same...

But it was pretty fast before doing the reset, I tried further resets, both hardware as well as software, but to no avail. The installation process is very slow, it took Facebook app atleast 5 minutes to install from apk file. Even installs from market take time and it's annoying.

See my other thread just posted. Assume this is because installs need to be converted from Dalvik to ART.
I know it was a lot faster under e.g. 4.4.2. But you sure it was also for any device with 5+?

I used this device for 2 days before messing up with radio band, i didn't face this problem during those 2 days and i used a Moto g3 for three months, didn't face this problem with that either. And it's dead slow, like currently my fb app is updating in background, it already has taken 12 minutes and is asking for another 3 minutes for a 45mb update.

I guess getting this phone replaced is the safest bet for me, as i have witnessed one more problem. When i keep the phone aside and pick it up after some time i see some strange coloured vertical lines on display at the right with rest of the screen being black. It gets right only when i lock and unlock the screen with power key. Any idea what it could be?

Hardware issue?! I would try and see what happens when you reflash it to full factory but that's of course only what I would do.

No signal [FIXED]

The problem got fixed a year ago.
The problem was the hardware and not the software
I've replaced the corrupt phone.

how you changed csc as u explained? usually flashing a diferent firmware with another csc will completly wipe the phone a d restore efs info, be sure ur flashing a different csc not included in the original csc pack (oxm and btu r the same csc for example).

maybe thats the problem, ILO and CEL r both the same CSC (OXM), if you dont flash other CSC it will not completly wipe the efs carpet, try downloading BVO from sammobile and flash it.
before flashing twrp or anyyhing first try your signal with completly stock BVO.

is wifi working ok?
had problems with my first s8 regarding gsm/wifi signal, got it exchanged to get it to work(it was stock untouched)

after a full clean flash of the official firmware go to factory reset from the phone settings, if that doesnt work im out of ideas, but after a clean flash, do all the process without the sim card and put it after the factory reset

After a minute without doing anything suddenly, my signal is back but it crashes every time i use it like to answer a call, i guess my antenna is defect, i will return my phone for a replacement.

Hi, have you been able to solve the problem? It happens exactly the same

Yes i have a similar problem, apps crash, phone lags all the time. I use 2 bluetooth devices connected all the time, location is always open, nfc is disabled, i use nova launcher prime. Phone is not rooted. Call drops when there is no reason. Cellular signals complete goes away even though it was at full service a moment ago, then after 10-15 seconds, it comes back again. This phone is making me really sick. I was using galaxy s5 before this and it had a better performance than this one. I have galaxy s8 g950f by the way.

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?

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.

Baseband not found [XT1766 SPerry/Boost Mobile]

Somehow or another I have managed to screw up my modem on my SPerry XT1766 (Boost Mobile).
I only get Emergency Calls Only radio signal, Settings app and bootloader info shows Baseband Not Found or Unknown.
I tried using RSDLite to flash
XT1766_SPERRY_SPRINT_7.1.1_NCQS26.69-64-10_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC
which contains the fsg.mbn and NON-HLOS.bin files, but this doesn't seem to help. I've tried multiple firmwares with multiple different modems and nothing seems to be getting my modem up and going. Back when I originally updated I flashed the partition updater also. I have no idea what to do now. I'm downloading the 69-56 version to try that, but I doubt it'll be any different. If anyone has any idea on what to do that would be great. Thanks

Try my baseband updater from this thread. https://forum.xda-developers.com/mo.../rom-stock-android-7-1-1-rom-moto-e4-t3885821
It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.

Are you on Boost network? I've seen the radio off problem with ppl using a different sim.

Yeah I already tried that but it jept giving me an error saying unknown command [ ]] or somrthing along those lines. i looked through the script and didnt see any typis. i think your NON-HLOS.img is different format than the NON-HLOS.bin files found in the stock firmwares, plus it's much larger. Anyways, tried a fastboot flash the modem with it and that didnt work either.

No I am not on a boost network but this problem goes more into firmware than network compatibility because the bootloadet itself isnt even recognizing the baseband. For the record I am still using a CDMA network like boost (Verizon)

Also as an update, the 56 version didn't fix it either

The latest update did that too many people. It won't work with a different sim. The radio will be off.
I bet if you put in a boost SIM, it would pop right on.
They changed something in the -8 firmware.
One guy building ROMs (not here anymore) made some changes to his build that got certain networks to work on his ROM.
He never got the chance to share exactly what he was changing.
It seems that if you booted the phone ever with the original sim inserted, it tripped a qfuse (of sorts) and it seems they have added a way for that particular reading to turn off the radio completely if you're not using one of their SIMs.

You are 100% on point. Sprint (and its subsidiaries) had Motorola Mobility to include code in an OTA update which would disable functionality of any network other than the original UICC (SIM). In other words, when you got a new Sprint compatible xt1766 (Sprint, Boost or Virgin Mobile), opened the box and booted the device with the preinstalled SIM in it, the xt1766 became forever locked to that network -- the OTA update carved that in stone. The update made it impossible to downgrade the baseband radio, killed all GSM functionality, and broke the radio on custom ROMs (the latter being unintended most likely). The only people I have heard of getting around this are the ones that didn't take the -8 OTA update. Like you were saying, I'd like to know what Jason M. done in his custom ROM to fix radio function, whereas at least the radio would work with the original SIM on a custom ROM. He said something about "adding missing symlinks" to the build.

I did this too somehow. I think this might bring your baseband back (it did for me), but... well, I'll get to the "but..." Anyway, Boot to TWRP, mount the Persist partition, then go to terminal or pull up an ADB shell and do:
chmod 0700 /persist/rfs/msm/mpss/datablock/id_00

Reboot with a SIM card inserted and voila, you maybe might have a baseband again. Hooray! Except in my particular case, I regained a baseband and then somehow lost an IMEI. Well, not really "lost," it's still there when I pull up the barcodes page... but on bootup it thinks it's 000000000000001. I still haven't ever fixed it, though I did manage to turn it to a single 0 somewhere along the line. Fkit.
But I don't know of anyone else who's lost their IMEI this way, and it's been too long ago and I've tried way too many failed fixes to remember what else could have triggered the problem to start with, so who knows. If you decide to try it, definitely make a backup of the Persist partition before you do anything...and make sure your backup turns out to be good first, not corrupt like mine turned out to be....sigh.

Try my baseband updater from this thread. https://forum.xda-developers.com/mo.../rom-stock-android-7-1-1-rom-moto-e4-t3885821
It will attempt to update your baseband to the latest version (M8920_15000.280.06.58.06R) from firmware build NCQS26.68-64-11. If this doesn't work for you let me know, I may have a solution.
