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?

Recently I've bought samsung galaxy S5 SM-G900R7. Today I have discovered, that this phone is CDMA only and it can't be used on GSM. Is that right? However, phone has SIM card slot. I'm a bit confused, why CDMA only phone has SIM card slot? Is this slot for LTE only? Or can I use other GSM carriers?
If this phone is CDMA only, can I replace motherboard with SM-G900F and use GSM network?
How about installing firmware of SM-G900F on SM-G900R7? Is it possible? Are motherboards of those models same and cellular network restriction is related to firmware only?
all g900's are gsm capable, but sometimes the ROM is built in such a way to not allow you to change it or the NV is locked to cdma with LTE, in which case it needs to be unlocked and can be done with several third party companies that provide such a service. www.idoneapps.com is my place of choice, they rock!! @Nodial is the man!!

Looks like this device is exception. It only supports 2 CDMA bands :/ Except this model, all other G900 phones are GSM capable. I tried idoneapps application, but it requires rooting. I tried to root using CF_auto_root, but after restarting there was boot loop with error "RECOVERY IS NOT SEANDROID ENFORCING". Then I installed the twrp recovery and phone turned on. BUT After restarting the phone and going to recovery menu, "android recovery" menu apears. twrp has gone I think this model has booloader locked. Phone is not rooted.

i dont believe that it is the exception as it would cost samsung more money to make it cdma only than it would be worth. bootloader being locked, now thats a possibility.

no, i dont think you can change the baseband without changing the bootloader, and flashing the tar.md5 for the G900F on your G900R7 will brick you phone so badly, youll need the debrick.img to save it. You could just flash a G900F ROM in recovery on it if you can get TWRP loaded, then the worst thing thatll happen is that youll need to Odin flash the tar.md5 for the G900R7 to save it
Hi guys,
Was able to get a LS997 in Canada. Carrier used is Fido.
Bootloader was unlocked using Dirty Santa.
When using stock based (sprint) rom, I always get an invalid sim error. This causes the phone/cell data not to work.
When using a lineage based rom, sim works perfectly and I get LTE data.
Is this behaviour normal?
Is there a way to make a non-sprint sim work on a stock rom?
Thanks
Update: Tried the WETA US996 rom on the device. Sim is recognized (since its the unlocked version), but LTE only works if I go in Network Mode, disable Global , enable LTE/GSM/UMTS, then set submode to "GSM/GPRS/EDGE only" or "UMTS/HSPA/HSPA+ Only" , then set it to "LTE/LEgacy 3GPP Multi".
This is a PITA since every time the connection is lost, these steps have to be repeated to get LTE data.
Any suggestion would be greatly appreciated.
I am running stock based rom to get the camera app and use the top screen.
Thanks

TWRP is already installed and the roms used are rooted. I looked but am unable to find radios/modem for the ls997.
If running AOSP based roms I have no problems getting LTE to work.
Aren't the radio/modem separate from the roms themselves, or are they included with could be the reason it glitches like that?
the phone itself is not carrier unlocked thats why you get invalid sim. when you use lineage roms they dont check if phone is carrier unlocked

Looking at the LTE specs for both phones:
LS997 : LTE band 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 25(1900), 26(850), 41(2500)
US996: LTE band 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 12(700), 13(700), 17(700), 20(800), 25(1900)
Source: http://www.gsmarena.com/lg_v20-8238.php
Fido requires 700 MHz on Band 17, 1700/2100 MHz on Band 4, 2600 MHz on Band 7
Source: http://www.fido.ca/consumer/content/configure-unlocked-device-guide
Bands 4 and 7 are a perfect match, and band 17(700) is a subset of band 12(700), so the LS997 should be 100% compatible.

Would you happen to know which modifications I would have to bring to make it so that I can get LTE working out of the box like Lineage for 997 on a 996 unlocked based rom?

You would have to use a us996 unlocked ROM with proper apns for your carrier in the apns list. The file is /system/etc/apns-conf.XML I believe

Edited my post above.
APN is properly set automatically on phone. As stated in the first (ERROR: second!) post, I can get LTE working, but need to set GSM/UMTS first then switch to LTE manually, and once the connection is dropped, this procedure has to be done again.
looked at the APN settings, they are the same as described by carrier.....anyone has an idea?

like me2151 said, flash the us996 based rom. Its the unlocked version that will allow sim cards from other carriers to be used.
The ls997 roms are cdma based roms that dont use the sim card for anything but lte and is a locked slot unless device is uicc unlocked by the carrier.
There isnt a method currently to uicc unlock this device without the carrier sending the code to the device.

Hello,
I am currently on WETA US996, but as described in the second post, I cannot get LTE to work without disabling it first, switching to GSM/UMTS, then activating LTE.
Once I switch over to Wifi for a period of time, then switch back to cellular data (example: leaving the house), I lose all data and have to disable LTE again, enable GSM/UMTS, then reactivate LTE to get LTE data.

have you tried a dif option such as global? or WGSM Etc? You may need to select a dif option.
@ME2515 also gave the idea to edit your apns master file in system, so its always holding the apns for your carrier, in theory it would force the device to keep the settings as they become the "default" all the time, vs the devices default auto setting for example.

Hello,
As explained in previous posts, the APNs are properly configured as per Fido settings automatically on the device. I triple checked to make sure all entries were correct.
LTE does work, but only going through the following steps: Go in Network Mode, disable Global , enable LTE/GSM/UMTS, then set submode to "GSM/GPRS/EDGE only" or "UMTS/HSPA/HSPA+ Only" , wait for a data connection, then change it to "LTE/LEgacy 3GPP Multi". Only then will LTE work, and once I switch to wifi, it won't get any LTE data when I disconnect from Wifi unless I go through that procedure again.
Am I really the only one with this problem?
Triple checked APN, it is correct. It's fetched autmatically from Fido when I connect to the network. Still no LTE unless I do the procedure above.
Reply in case someone encounters this issue. The APN setting for LTE was the culprit. I setup the APN as it it weren't an LTE device following the fido directives (using Fido-core-appl1.apn instead of LTEMOBILE.APN) and now get LTE connection when network is set to global.

ouch...that was long ago. I do not remember. I bought an unlocked US996 afterwards and sold the 997. Now with an S9+, which again gives problems..lol
I got an unlocked GSM AS993 on Ebay. Sure, it's frustrating how locked down the bootloader and stuff is but my one true issue is that it's a "GSM unlocked" phone and mostly works correctly except that it has default, baked-in APN settings from C Spire that it keeps defaulting to on reboot, sometimes overwriting the Ting APN settings I need for my MMS stuff to work. It will also occasionally do this while the phone is *running*, swapping out my Ting APN's MMSC for the C Spire one. It does this even though I added a separate APN for Ting. It overwrites the one I added!
Is there a fix or workaround to stop it from overwriting my APN settings? Preferably without doing the painfully complicated flash-three-images-together method used for rooting
I have this same issue but it defaults back to Sprint settings. Anyone know how to fix it?

Hi, good news! I found a solution. Bad news: had to flash a completely different ROM compatible with my device and region (United States) which of course means wiping the device completely.
I used a patched version of LG UP, downloaded Canadian (H873) firmware, did a full partition DL to write all the partitions to the device and after a lot of time it booted and I had a working G6 with zero carrier bloat and it didn't mess with my APN settings after that. I did a full factory reset before & after installing the firmware but you'll lose all the data on your phone either way, so do be aware of that.
Factory reset is performed by booting up holding power button and vol-down, releasing ONLY the power button for a split second when the LG logo appears and then pressing it back down again until the reset menu appears.
Firmware version I got was H87320i_00_OPEN_CA_OP_0204 from lg-firmwares.com
I got the installer for LG UP and the patch files from Jthein's excellent UnBrick thread.
most excellent tip

Hi, good news! I found a solution. Bad news: had to flash a completely different ROM compatible with my device and region (United States) which of course means wiping the device completely.
I used a patched version of LG UP, downloaded Canadian (H873) firmware, did a full partition DL to write all the partitions to the device and after a lot of time it booted and I had a working G6 with zero carrier bloat and it didn't mess with my APN settings after that. I did a full factory reset before & after installing the firmware but you'll lose all the data on your phone either way, so do be aware of that.

Thanks for the tip, this seems to have worked for me. Being on T-Mobile I would like to have Wifi Calling and VoLTE working as well, which the H873 ROM is not showing in the menu options. I understand the US997 phones have these options enabled and work on T-Mobile, not sure if cross flashing AS993 -> H873 -> US997 will work or not. If anyone has tried this I'd be curious to hear of success or failure.
I don't remember for sure but I think I may have cross-flashed either an AS993 or LS993 to US997, a long time ago. Why not give it a try? Worse come the worse, it will give you an error in LG UP and stop the process or even if you manage to brick the phone, just follow the unbrick guide that Mike_IronFist linked. With the firehose out for the g6 long ago, you can't really brick it permanently (except don't mess with H873 as it can't be cross-flashed).
if rooted use gravity box or decompile framework apk gravity box has the option under framework device_respects_carrier_config=true change to false and change_apn to true
Hey team,
I have an SM-A205U that apparently was flashed for Sprint or Boost. I put a Spectrum (MVNO) sim in the phone and it works, but I can't get rid of the Sprint device registration failure notification. I think I saw during bootloader that it lists BST as provider.
I haven't been able to figure out how to get rid of that Sprint branding. It also shows up in "About Phone".
Which firmware do I need to load to get rid of it? I looked at sammobile, but don't know which one I need to download to have a brand-free firmware.
Any thoughts?
Do *#272*yourimei# and change csc to xaa and it will reboot and branding will be removed

I tried that (just go to phone and dialpad that in?) nothing happened for me. I have a 205U that is locked to metro (metro bootup and stuff) im trying to make work with sprint.
Popping a sprint sim card in it I can't activate it.
