Have a Samsung Galaxy Note 3 (model: SM-N900W8) and wish to enable LTE for a specific carrier? Follow these in-depth instructions and you will enable LTE for this specific model. My Samsung Galaxy Note 3 model is from WIND Mobile and I use both WIND Mobile and Telus SIMS on the device (interchange when needed). When using WIND, I get their default 4G data speeds and with Telus, I now have LTE which is like going from a Honda to a Corvette.
These instructions will work with all the SM-N900W8 models but you will need to select the appropriate root for your country/carrier (as indicated in Chainfire's post).
Should you have any questions, please respond to the post or send me a PM and I will assist where possible.
Thank you to the following 3 individuals! Some assisted with their general posts while others provided informative information via PM to ease me into the process:

UNLOCKING YOUR DEVICE
Before you are able to use another carrier SIM in your device, you must first unlock the device. I know there is a method of doing this for free after rooting but I paid $32.99 USD and received my unlock code through cellunlocker.net. If unlocking to use a SIM from another country, make sure you first activate with the original SIM. Failure to do so will region lock the device so you cannot use it with an International SIM. The only way around this is to pay a Samsung technician to reset the device. Since I use WIND and Telus, both carriers are Canadian so I went ahead and unlocked my device using the Telus SIM directly as I do not need to worry about a regional lock.
ROOTING THE DEVICE
1) Download and install Kies (for the Drivers) from here http://www.samsung.com/ca/support/model/SM-N900WZKEBWA
2) Download the ODIN software and ROOT provided by Chainfire:
http://forum.xda-developers.com/showpost.php?p=46098951&postcount=3
3) Unzip the files just downloaded and run the ODIN software. Once loaded, click on the PDA button and browse to the ROM file:
CF-Auto-Root-hltecan-hlteub-smn900w8.tar.md5 (this was the file I selected for my Canadian provider as my device is WIND Mobile). Make sure the check-box in the ODIN software that says "Re-Partition" is either unchecked or greyed out.
4) Power off your device and once off, reboot into the Android system by pressing Volume Down + Home Button + Power (all at once). When you see the Galaxy Note 3 logo, let go and it will present you with a warning regarding installation of customized OS's. Click on the volume up button and this will allow you to continue and present you with a Android logo screen and the word "Downloading".
5) Plug your device into the USB port and click on the "Start" button within the ODIN software. It should take a couple of minutes but the status window in ODIN should say successful.
CONGRATULATIONS... You have now rooted your device!

INSTALLING TWRP (TEAM WIN RECOVERY PROJECT)
I loaded the above program which I recommend you do as well. TWRP is a fully touch base recovery software program that allows you to store/backup and save custom ROMS either to your computer or to the device itself through internal storage or external SD. Think of it as a simple way to manage your device rather than having to enter a bunch of codes or press key sequences to get into specific low level menus of your device.
The software can be downloaded from the following link. I downloaded the latest 2.6.3.4 version:
http://goo.im/devs/OpenRecovery/hltecan
1) Power off your device and once off, reboot into the Android system by pressing Volume Down + Home Button + Power (all at once). When you see the Galaxy Note 3 logo, let go and it will present you with a warning regarding installation of customized OS's. Click on the volume up button and this will allow you to continue and present you with a Android logo screen and the word "Downloading".
2) Load the ODIN software, click the PDA button and select the TWRP package you just downloaded:
openrecovery-twrp-2.6.3.4-RC1-hltecan.img
3) Plug your device into the USB port and click on the "Start" button within the ODIN software. It should take a couple of minutes but the status window in ODIN should say successful.
CONGRATULATIONS... You have just installed the TWRP software which will open your device up to a world of possibilities.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
INSTALLING AN LTE CAPABLE ROM/MODEM
Now that you have your device rooted and the TWRP software installed, we now want to enable the LTE capability so you can use this device at the best speeds possible! Unlike what many have posted, I confirmed with AllGamer you can load any carrier SM-N900W8 ROM onto the device as long as the models version match (ie: SM-N900W8). My device is WIND Mobile and this carrier does not support LTE so the fastest speed I can select is 4G which is WCDMA/GSM in the network mode settings. Since I will be using the device on Telus with LTE data speeds, I want to install this ROM but ensure the device will have LTE as a option which I can select under network mode.
1) Go to the following link and download the carrier specific ROM for the provider you wish to use your phone with (in my case, Telus):
http://www.samsungis.com/Firmwares/SM-N900W8.html
2) This is a large file so I downloaded it to my Pcloud account then onto my computer which took about 30 minutes. Once the file is on your computer, extract the contents.
3) Power off your device and once off, reboot into the Android system by pressing Volume Down + Home Button + Power (all at once). When you see the Galaxy Note 3 logo, let go and it will present you with a warning regarding installation of customized OS's. Click on the volume up button and this will allow you to continue and present you with a Android logo screen and the word "Downloading".
4) Load the ODIN software, click the PDA button and select the ROM package you just downloaded (in my case, Telus):
N900W8VLUBMJ1_N900W8OYABMJ1_N900W8VLUBMJ1_HOME.tar.md5
5) Plug your device into the USB port and click on the "Start" button within the ODIN software. It should take around 5 minutes but the status window in ODIN should say successful.
6) Your device will now reboot and you will need to go through the setup process. Once complete, you think LTE will be enabled but you are wrong! You must dial the following key sequence to bring up a regional carrier menu: *#272*[IMEI]# (that is *#272* (your IMEI number) #) - To find your IMEI number, check your manufacturer box or press *#06# from your call menu and it's the first 15 - digits.
When the menu pops up, it will show a listing of codes and it matches the "region" list that's shown at the following link: http://www.samsungis.com/Firmwares/SM-N900W8.html
When the menu comes up, select the regional code for the carrier ROM you just installed (in my case, Telus which was "TLS"). 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.
CONGRATULATIONS... You now have rooted your device, installed a custom ROM for the carrier you wish to use LTE on and have LTE capability. Since you have installed a specific ROM and set the regional carrier settings to this ROM, if you look under your status menu, instead of it saying "Custom" next to "Device Status", it will show "Original".
I hope this information helps others who have been stuck with enabling LTE on their device. Remember, LTE will only work for carriers who support LTE capability. Should I switch my SIM card and put my WIND SIM back into the device, it will work but the MAX data speed I will get is 4G.
Good luck everyone and again, please thank the above 3 individuals for the countless amount of times they have helped us members out with our problems!
Great post!
seems like the most important part was step #6
that was the missing info to complete the LTE setup.

Thanks! Look at everything that can be accomplished with a little hard work, dedication and assistance from those in the know. I only wish I was able to figure this out sooner without bricking a device. A costly mistake but a learning experience so all in all, no complaints!
will this work for the N9005 model?? I currently have
AP: N9005XXUBMJ1
CP:N9005XXUBMJ1
CSC: N9005OLBBMI3
Im using T-mobile right now, and would like to know if its possible to get the LTE for T-mobile in the US.
Thank you
So let's say I have a Mobilicity N3, and use this method to install the Bell ROM. Does this mean I now have a "Bell" N3? Will the OTA updates still work? Will this cause any known issues? If I factory reset the phone, it will be reset as a Bell N3?
Theoretically, installing any of the Big 3 (Robellus) ROMs should do the trick from an LTE perspective, assuming you've SIM-unlocked the phone, yes?

Hi, i have an N900W8 Rogers Note 3. I have a T-Mobile rom flashed on the phone., however, my baseband is still MJ1 (Same as my Rogers stock rom). And im having Poor LTE reception. Can you provide a CWM flash-able zip modem i can flash that might fix this issue? Or can i download the stock rom myself and flash ONLY the Modem? Thanks!

I suggest to do verifications before you flash a modem. Call Rogers and ask tell to do a "resend to switch". Call from an other phone if u can and listen to instructions
Also, update the phone to the latest firmware to have the latest modem.
Info: you can flash kitkat although the approved version by Rogers itself is not out yet.

Hi, i am with Fido. The Note 3 is from Rogers though (Same company). I dont want to flash the entire stock rom is the reason im asking for only the modem. I was wrong before, currently im using an N9005 Note 3 rom called Hawkish Elite. And the rom i was on prior to this one was the T-Mobile Note 3 based Darthstalker rom. I really dont want to have to flash the stock rom. So any information would be greatly appreciated. Thanks!

Rogers LTE issue
hello all,
I was wondering if someone could guide me in the right direction as i need help enabling LTE on my phone on the rogers network.
I came across a thread about enabling LTE on the SM-N900W8 model of the samsung galaxy note 3 (the one i have)
I do not have LTE showing up on my phone, i tried speed test and the best i get is 4G with 9mb download speeds.
I actually sent my phone in to repair and the gentleman swapped out the motherboard to change the IMEI legally.
Its an unlocked phone at this point and it has model number SM-N900W8, ive gone into the settings and selected LTE coverage but it doesnt give me more than 4G.
getting back to the instructions on the thread, i had a couple of questions.
If my phone is already rooted to another version can i follow the step by step instructions and "re-root" over the existing root which is the second instruction after unlocking the phone itself in this thread. Will it "brick my phone?"
on The third set of instructions for installing an LTE capable ROM/Modem i dont see any rogers options when i click on the link...can i load a Bell one as currently i think my phone had a bell one installed onto it as it had Bell TV bloatware etc when i got it back from the motherboard swap out. IT IS an original Rogers phone.
your guidance on this matter is greatly appreciated, i was so happy to search and find a thread helping with my needs!
First post!
I have a Fido firmware on my device (country code FMC)... and I'm using it with Virgin Mobile. Do I really need to do all those steps if connecting to LTE is not really a problem right now? I did not do a speed for now because LTE coverage is nearly non existent where I am... but I see it connecting to LTE.
If I do all the steps to change the ROM and CSC, will it format/reset my device?

Also for those unaware you can force LTE only by typing in *#2263# and Selecting LTE Band Pref -> LTE ALL
Please note you will be unable to receive a voice call as (in Canada at least) calls are still handled on the UMTS/HSPA network as no carrier I'm aware of has VoLTE yet.
...and if one switches over to LTE only, can that same phone be put back without issue? any tested?

You mean if I activate lte this way I won't be able to make calls? Do I have to disable enable lte everytime I need lte?

This worked for me. I now have LTE on AT&T.
Thanks!
I hope there is not a super obvious solution I missed somewhere, I apologize if I am hasty in posting this question, but I cannot understand why my AT&T l337 is not working with my Canadian mobile carrier, Wind Mobile. I do not get the network lock screen with the pin/dismiss options, and the phone picks up on signal, but it gets no data and still prompts "emergency calls only" when I try to make a call.
Phone is rooted stock 4.2.2 NC1, safestrapped, with an MF3 modem. I got the phone new when it was already on NB1 in May 2014, so the service menu unlock method was obviously not an option. I followed the steps in method 3 (@NewToGalaxy) from the @bvzxa3 "possible method to sim unlock" guide, http://forum.xda-developers.com/showthread.php?t=2595457, it does not seem to do anything but remove the initial "pin/dismiss" network lock.
I tried enabling AWS using the "enable AWS on AT&T samsung S IV" @zaryan guide (http://forum.xda-developers.com/showthread.php?t=2291589), but when I try to enter the *#7284# into the dialer for step 3, I get the same "Connection problem or invalid MMI code" I get when trying to use some of the options in the *#0011# service menu.
I have searched around XDA, but I did not find anyone who was experiencing the same issues I had. What am I doing wrong? Flash the MF3 modem, run regionunlock, insert non-AT&T sim (and all the combinations of steps therein). How can I enable AWS if my phone can't access those service menus?
Based on the information cloud-x provided in his sim-unlock thread http://forum.xda-developers.com/galaxy-s4-att/help/i337-sim-network-unlock-assistance-t2808211, it seems like receiving an unlock code from AT&T is not an option since I'm only three months into a contract, and normal unlock code vendors may not be able to pull codes. At any rate, I am in Canada for a limited time and I hope to solve this issue before I return to the states and cannot test my Canadian sim.
I'm sorry I'm kind of a noob and if this situation or issue has been dealt with before, I just hope someone can point me in the right direction.
http://forum.xda-developers.com/showthread.php?t=2285431 follow the state at the beginning of this thread after rooting and installing shortcut master lite use the secret code explorer and scroll down to code 27663368378 there you will see all the options needed. I was on NC1 when I did this
I337 stock NC1, rooted, unlocked
Sm-T537A NE1stock, rooted
Bought this tablet on eBay cheap. Then realized it's Sprint. Thought about the NV edit to add band IV LTE, but could not get passed the MSL requirement. Sprint was no help. Same with the apps, save for one that I found here. The Sprint Samsung Galaxy Unlock apk sometimes after a reboot I get the Invalid SIM error. This apk solves that quickly.
My intent was to first clear the current carrier information. Such as the user name and anything relating to Sprint.
I have at my use an Octoplus box with latest software.
I threw everything I could at this Sprint tab including flashing via Octoplus the firmware for SM-T337A (AT&T). Which did not take nor brick my device.
I have the SM-T237P rooted with the detoxed firmware found on this forum.
I used Octoplus box to (likely wasn't necessary) flash the AT&T version SM-T337A.
This model (T337A) was useful to unlock my Sprint tab 4. I can't tell if it was necessary or not, but the process completed.
Then I found another model (T335) that had the option to Fix the MSL via Octoplus. This version is a Tab S model SM-T335.
I pressed the button and rebooted the phone.
To get into Diag-DM-ABD mode is required for any operation. EFS Professional can do this or there is a way into the service menu on the tablet.
On the SM-T237P make sure you have an active wifi connection. Then go to General | Activate this device | it should fail saying call customer service by pressing *2 on your phone. The three dots at the top right will allow access to the service menu. Click on PST and you will see the ##DATA## and several other menus. From here you may change anything, if you found the MSL.
Repairing the MSL via Octoplus opened up the menu to edit the MIN and MIDN which doesn't really help me at this point.
In the service menu look for the third option down | LTE Services | click on Global and restart the device.
After reboot under | About Device | Status | my regular GSM sim card is seen and the number does show up.
That particular chip is out of service, but I did achieve my goal of removing the previous sub info.
Also new is the option to select many new network modes. I will get screen shots of what I am attempting to explain.
I had read a lot and not found too much on this Sprint SM-T237P
I understand it does not have the frequencies to be used on Wind Mobile. I should find a Bell chip and see what happens.
This is the culmination of a month's work. Utilizing Google, XDA and the Octoplus box. Some things I have done may be contrary to the user manual or common thought. When testing your new device and there isn't much that others have done, you must think outside the box and not be afraid of bricking a device. This is just my experience. Following is my log from last night.

My question to the forum: Was it the MSL Reset that flushed the Sprint subscriber info or was that the unlock or maybe just enabling LTE Global which never stuck until I did the MSL reset. Fun, fun testing.
Any updates to your efforts?
Any way to root T237P on android 5.1.1? Without root i cant reset MSL which is necessary to stick the global mode.
Galaxy Tab 4 T237P Sprint
To set global mode:
Open stock calc app tap (+30012012732+ - in Factory Mode put ##3282# (equivalent to ##DATA#) - then tap SPC/MSL (you can read it by enabling DIAG and using z3x Samsung Pro) then menu More > HDR1x selection > Global > Yes
To Enable Diag:
Open stock calc app tap (+30012012732+ - in Factory Mode put ##3424# (equivalent to ##DIAG#)- then tap your SPC/MSL > tap Qualcomm USB setting > DM + MODEM + ADB
I tried to set Korean Mode to Indian and this enabled WCDMA / GSM Mode, APN settings and more
also can be sim unlocked using ssu.apk on Android 4.4.2
Will the Sprint Tab 4 work on Att GSM after your resolution i.e. setting the global mode and enabling Diag mode.
I bought this tab Samsung Galaxy Tab 4 sm t237p from eBay and was told it could be unlocked for gsm use in Africa. But despite all my efforts, I can't seem to get the tab to recognize the gsm networks. I live in Africa and from what I've read, it ought to work outside the US. I have the msl code and was able to put the tab in global mode but that didn't make any difference. I've rooted it and installed philz custom recovery. Tab runs on android 4.4.2. Can anyone help me out or point me in the right direction?
My father brought me a Samsung sm-t237p tab in new your he came to Trinidad western design and it do not work its still lock on sprint network. I have the imei number.how can I put it on the b mobile net work hete

I called Sprint customer service (always chose "other option"), and had to argue a little bit to get them to provide me the unlock code.
Once they did, I followed the instructions above, entered the 6 digit code they gave me, and now my tablet is SIM Unlocked.
Be warned - This did a factory reset and erased everything!
I just got the Sprint tablet, SM-T237p yesterday. I did the OTA upgrade to Android 5.1.1 last night.
This morning (actually, 5 minutes ago) is when I did the sim unlock.
Thankfully, the Sprint activation nag is now gone. (I got the tablet on Amazon due to price - I never intended to use it on cellular network, but the Sprint tablet with 16GB was cheaper than the wifi only version with 16GB)

Thankfully, the Sprint activation nag is now gone. (I got the tablet on Amazon due to price - I never intended to use it on cellular network, but the Sprint tablet with 16GB was cheaper than the wifi only version with 16GB)

So are you saying you have the T237P working on a GSM network?
search specs of this tab.
even if you could unlock it wont work because no gsm radio.
Cellular Networks: CDMA800 (BC0), CDMA1900 (BC1/BC14), CDMA800 (BC10)
Cellular Data Links: cdmaOne, CDMA2000 1xRTT, CDMA2000 1xEV-DO Rel. 0, CDMA2000 1xEV-DO Rev A
I'm wondering if its in the modem hardware or the programming because IF it is in the programming maybe it is possible this guy got it working by somehow flashing att radio in odin (seems like it will fail or brick or destroy efs, nv, etc info) and then unlocking all bands. All of this seems pretty suspect and I am pretty sure this is a dead horse

Is it possible to get this unlocked from Sprint and use it on a GSM network? I just got one of these and I have Metro PCS

idk about that.
I did try a StraightTalk SIM and a VZW SIM and with both of them the tablet gave error about invalid SIM card.
I just took this tablet out of service last month. It still works perfectly fine, but, dang, who wants to still be using Lollipop? :laugh:
were i able to unlock this way ?
My tab 4 10.1 ( sm t 530nu matissewifiue andriod 5.0.2) is missing the 'unlock oem' button in the dev options. ..
I don't have access to a computer, and I'm about as green as they come...
I've tired multiple troubleshooting fixes, searched the Web high and low for an embarrassing amount of hours, and the best thing I've come across is loading twrp in recovery (since I can't load it myself) / forcing the bootloader thru a virtual andriod. I've Seen The option to do so in 'vphonegaga' but before I could do anything about it the app kept crashing ... so round two is xposed virtual andriod. ... only I can't find the same option in this app. So once again i, scouring the Internet to fund the solution. But so far this virtual andriod app is stable as can be, im asolutely thrilled that it can master the very choppy and crash happy waves of my crappy tablet, so much so that I sent the last of my bank balance (enough for a coffee atleast lol- it's not much but its better than not showing my appreciation at all) just to say thank you
....and if your still reading after all that then you may as well not let the time- and effort you've already spent- go to waist by not replying
first I'd like to thank all the different people on multiple forums that put in all the work with what I gathered here to make a simple guide on what got me a domestic sim unlock for my SPH-L720T
I know there are other guides out there, but I couldn't find any clear and simple methods to do this; there were a lot of things where I had to dig and scratch my head for information, so I will post step by step how I did this and try to make it clear and easy. This is all free and requires no unlock service.
I currently have my SPH-L720T on Straight Talk with Talk, Text, Data, everything working. I ran through and made phone calls, texts, picture messages, checked the internet connection etc. All worked with an ATT sim card that came with my Straight Talk Activation kit. I havent tested T-Mobile, or other sims. But i can verify for you the ATT sim from Straight Talk works.
This is what I did step by step and what worked for me, I'm not responsible for what you do.
Step 1
1st off you need to root, this was extremely easy with chainfires CF Auto Root, and it worked on 5.0.1
http://forum.xda-developers.com/showthread.php?p=41743595#post41743595
just carefully follow the directions, it worked perfectly.
Step 2
next you need to flash the MK5 modem
put your phone in download mode (power your phone off, then hold volume down+home+power. their will be a prompt menu and it will warn you, but just continue by pressing volume up),
next open Odin which you should have from the CF Auto Root process, connect your phone to your computer with your usb cable while its in download mode, Odin should recognize it and you should see it says its been added.
Now flash the MK5 modem. You do this by clicking on the PDA / AP button in odin and selecting the "modem-L720T-MK5.tar.md5" file I provided. Make sure the re-partition option is not selected in Odin, now click Start. Odin will run its process and once your phone reboots, I got a quick notification saying that android has successfully updated. Then you can check in your "About Device" settings in your phone to verify you're now on MK5.

Step 3
Next you actually Sim Unlock for domestic use, this is the part that took the most time searching for something that worked, I used the Galaxy Tools .apk app from idone.apps. You can purchase it or obtain it by other means, but just make sure its up to date, v3.1.8. is the version I used
http://idoneapps.com/instructions.php#msl_sam
When you open Galaxy Tools .apk, you'll see a MSL/SPC: number which is your unlock key, you dont need to do anything with this, because on the option / button called SIM UICC Unlock, all you do is click the button, and it uses the MSL number to unlock your sim for you. If you've successfully Unlocked your sim, it will say in bold letters "SIM uicc: UNLOCKED"
If your MSL/SPC says UNKOWN then you probably need to update your Galaxy Tools .apk or reinstall, I had to update mine, then it worked like a charm
note: I know some other people had success with SSU.apk the samsung unlocking app, but it wouldn't work for me, the app would force close, try SSU.apk if you like
http://forum.xda-developers.com/spr...print-samsung-unlocker-unlock-sprint-t2928250
Step 4
Next you need to modify your GCF settings via the service menu. Open your phone dialer, and follow these instructions
Dial *#0011# and in the service menu do the following
Click (menu) then (key input) then input Q then (Ok)
Click (menu) then (back)
Click (menu) then (key input) then input 0000 then click (Ok)
Wait for about 15 seconds then a menu will pop up, from there follow these procedures:
Click (UMTS) then (DEBUG SCREEN) then (PHONE CONTROL) then (NETWORK CONTROL) then (GCF) then the top option. From there you may press the home button and go to Settings and change the mobile networks to either Automatic or GSM.
note: these directions for the service menu were from user F_X here, http://forum.gsmhosting.com/vbb/f453/how-unlock-l720-l720t-1980164/
Next all I needed to do was modify some settings in the Mobile Networks section on my phone
Change your Network Mode to GSM/UMTS, you can also choose Automatic, but I have it under GSM/UMTS.
Step 5
Lastly you need to add an APN setting so you can actually use your service, for Straight Talk I use these settings
go to Settings, under Mobile Network settings to Access Point Names (APN) and press the + button to add a new APN.
Enter Name: Straight Talk
APN: tfdata
Proxy:
Port:
Username:
Password:
Server:
MMSC: http://mms-tf.net
MMS Proxy: mms3.tracfone.com
MMS Port: 80
MCC:
MNC:
Authentication Type:
APN Type: default,admin,fota,mms,supl,hipri
Keep default values for all blank fields shown above.
Press menu button (top right) and select Save.
note: these settings I got from here, https://apn.gishan.net/settings/752_11_straight_talk_apn_settings_for_samsung_galaxy_s5.php
If you already have your Straight Talk Simcard in, then you should literally see the 3G icon and everything active almost immediately, it was for me at least.
-----------------------------
Thats it, you should be good now. Some other notes I would add, would be that I THINK, and I repeat THINK, you can lose your SIM UICC UNLOCK in Galaxy Tools .apk if you flash to another ROM or upgrade your OS, I never really found a clear answer on that, so I am leaving this phone with the stock ROM so I dont lose my SIM Unlock, but please share if you know more about this.
Also please share more info so I can update this Guide if you have more knowledge, which I KNOW theres more info out there on this to be added. Or if theres a mistake in my guide lol (pretty sure I covered almost everything I did in my own process.) I dont know if this will get moved or what, but it will prob be associated with the section about unlocking in the [q] ALL THINGS GALAXY S4 (GS4) MODEL SPH-L720T under the "UNLOCKING FOR USE ON OTHER CARRIERS" section here, http://forum.xda-developers.com/showthread.php?p=56584245#post56584245
Again thanx to everyone I sited, seriously..!

My baseband is OH1, I'm not sure if that's 5.0.1 or 5.1.1 cuz I'm on CM13 atm. Any insight as to if I could still use this guide before I just go willy-nilly flashing back and forth?

I did this on 5.0.1 stock, so I'm not 100 about custom roms, I wish I had a solid answer. Although I think I read ppl did this on stock Android, then flashed roms. But if the sim unlock will stay, is the question, please let me know if it works for you, try a backup beforehand, I think I heard that SSU.apk's sim unlock sticks better than Galaxy Tools .apk regarding flashing to custom roms afterwards

It isn't compatible with custom ROMs, I know this ahead of time. I meant asking what baseband OH1 came from (its 5.0.1) so I would be able to revert to stock, test the unlock then flash back to CM13 and test the unlock sticks or not
Does it work for international carriers?
OP, I've installed and run the Galaxy Tools / idoneapps apk version 3.1.8, but it shows MSL/SPC field = unknown and SIM uicc = NOT SUPPORTED. When clicking the "SIM uicc unlock" button in the app, I am prompted with an popup dialog titled "Network UnLock" and a field named "Enter Control Key" to be filled in. Not sure if the MSL code is expected there. I happen to know my phone's MSL code. After entering it and hitting "OK", it shows "Unlock request unsuccessful".
What may be wrong? I am on OK3 stock Sprint ROM, rooted, and baseband downgraded from OK3 to MK5.
Lollipop 5.0.1
The Galaxy Tools 3.1.8 apk doesn't seem to be able to do its magic/do the unlocking.
Thank you.
Hi All - hoping to get your help and advice.
Original S8 was a USA SM-G950U on T-Mobile that was successfully flashed and unlocked to SM-G950U1 (CSC = XAA). The phone was fully functional, successfully received OTA updates and was on the latest firmware (G950U1UES5CRL2) in use in Hong Kong (3HK 4G LTE) until yesterday when I did a hard-reboot and cache-wipe a few days after a system update and now the cellular radio won't connect to any network. I've tested the SIM card (works fine on other phones), rebooted without the SIM inside (no impact), tried upgrading to Android 9.0 as well as older Bootloader v5 firmware to see if the cellular radio would turn on and re-connect but no luck.
Current State: When looking under "Mobile networks", Network mode shows "Preferred network mode: CDMA/EVDO/GSM/WCDMA" whereas it used to be "LTE/3G/2G". This option is available under the drop down list but I can't selected it. Under "Network Operators", tapping "Search networks" results in an error "Error while searching for networks". Tapping "Select automatically" pops an error "Unable to connect. Try later".
After exhaustive testing, it feels like the phone is behaving like it's SIM-locked since everything else works thru wifi but it's on the SM-G950U1 XAA unlocked firmware so it shouldn't be locked?? Any suggestions would be greatly appreciated.

Just because you flash unlocked firmware does not remove the T-Mobile SIM lock

Thanks for your feedback! What's strange was that my S8 with the unlocked firmware (SM-G950U1) was working perfectly for 6 months and I was able to make calls, get LTE data connectivity, etc. Now the phone is still working via wifi but the cellular function is dead. Any suggestions or advice on how to remove the T-Mobile SIM lock?

We need to verify some how if it truly is Sim locked or not first.

I've tried 2 different SIM cards (though both from the same carrier) and both were not connecting to the mobile network. The phone can detect when there isn't a SIM card inserted so that is a minor indicator that the SIM card slot is functional.... any other suggestions on how to verify whether my S8 is SIM locked?
EDIT: Both SIM cards work in other phones (iPhone6s, iPhoneX).

Of coarse not always but most of the time it will display a warning or something about sim not accepted. This sounds like to me. A couple things. Simlocked. Maybe install the T-Mobile firmware again and try the T-Mobile unlock app. It should say this device is already unlocked or successful. If that passes. It could be a disabled band or something. Sounds like the latter. Like it's not picking up your carriers signal. Again the us models I believe are pretty universal so maybe a different firmware may enable it again. Or last the device has somehow become blacklisted which unfortunately I have seen plenty of people here in US sell devices still on contract maybe pay a few months and quit then blacklists

You can't fish 950f different chipsets. What country are you trying to use it in. If it's blacklisted that's more than likely your answer right there.

Yeah can't flash 950F, Russia - No T-Mobile here. Don't know what to try right now, possible try get stock TMB, then unlock network again if its lock. No blacklists, T-Mobile support says status Clear, but maybee contract on T-Mobile not paid. Trying to flash custom modem, but didn't help too.
