I bought a S7 Edge G935F, manufactured in Brazil (stock ZTO G935FXXU1APB4), and I decide to update my device with another country rom, because my phone is heating up using basic applications like whatsapp.
The frequencies 4G FDD-LTE that I will use Band 7 (2600MHz) and Band 28 (700MHz).
Doubts:
1) How do I check which frequencies are available on my device (forget manual device). Some app?
2) If I flash another G935F country rom by Odin, is the modem file "cp" has the power to change the frequency? Have the risk of losing the bands 7 and 28?
3) What is the unbranded rom that has less bloatware: BTU, XEF, PHN, XSA?
Thanks community, thanks people.
Attention who bought S7 Edge runbranded in Brazil: on first boot after unboxing, the "Do Not Disturb" simply not open to set up; the heating was more than usual. Then I did a factory reset from the device menu, now everything is normal, with no heat, "do not disturb" function normal. Finally, the tip is: give the first boot without setting anything (jump all settings and without connecting) and make a factory reset.

I am really new to the world of ROOTING & FLASHING and have already bricked one device. I have followed a lot of information provided by the gurus on here but am at a standstill with my new device as I cannot afford to brick a second one due to my lack of knowledge when it comes to this stuff.
I do not wish to root my device at this time but did read the post talking about "regional" lock. It seems this is only relevant if people unlock their device through the rooting method. Since my device is from WIND Mobile (unactivated) and I purchased an unlock code from cellunlocker.net, I assume I can input my Telus SIM and I would not have to worry about a regional lock? As I understand, the purchased unlock code would supersede the regional lock correct?
As for Telus... When I unlock my WIND device, I assume it will be like my original where Telus voice worked but data was limited with 3G. This was due to the radio band for LTE being crippled in the device. I was told without rooting, I could still use the device with LTE but would have to FLASH the LTE modem through the ODIN software. When I look at the link which provides "flashable" modems, there is nothing there for my specific model.
AllGamer posted a modem (.bin) file for the Puerto Rico modem which supports LTE but confirmed with me this is not a file which can be flashed through ODIN and has to be packaged (or something to this affect). This is all too new to me and so if anyone could provide the steps to FLASH a compatible LTE modem onto my device without rooting so I have LTE support enabled, this would be great!
Thank you!
Issue is resolved. Currently, you cannot just flash the modem and must root and install a custom ROM supporting LTE. Once this device has been out long enough, the possibilities of modification will be greater but for now, my device from WIND works with Telus and has LTE data.
First, Telus, Rogers, Bell, Wind....all these carrier carry the same model of Note3 and running the same ROM
all you have to do is pull out your Wind sim card and do a factory reset. Then put in your Telus Sim card.
Phone will find Telus CSC setting and set it up as Telus phone.
As long your phone is sim unlock with Wind Mobile, any Canadian carrier should be working with your phone
About LTE, maybe there just don't have any LTE signal in the area, or your LTE setting has been turn off.
All you need to do is go into setting check under network and see if the phone is running GSM/CDMA/LTE or GSM/CDMA only, just switch between 2 and you will get your LTE with Telus LTE sim.
You don't have to worry about region code once your purchase unlocked online. region lock only apply when the phone never activate with local sim card and trying to activate with sim card from other countries. Just put in your Telus SIM and setting up the phone. Wind has this phone becuz it support AWS network, it doesn't mean the phone come with different modem!
Since you are not looking to root your phone or anything....there really no need for any flashing!

You are only partially right with your response. Look at my other threads with how to get things functional. First, the phone is the same model for each Canadian carrier but as per the agreements between the carriers and Samsung, specific bands have been crippled. I unlocked my Note 3 so yes, the Telus SIM will be recognized upon a factory reset and will pick up the correct APN settings but since the LTE modem has been crippled, the device is great for voice but has sloooooow 3G data.
In order to get the device working with LTE, you must flash an LTE capable modem onto the device. Since this device is new on the market, no modem (.bin) file has been made flashable. At this point, the only option is to root your phone. Even when rooting and installing the Telus firmware (ROM), this will still not enable LTE as there's a safeguard in the device. Once the phone has been rooted, you must go into the regional settings for the device and select the carrier setting for the ROM you just installed. This will format the device and reboot with your carrier setting thus enabling LTE/WCDMA/GSM (auto connect) within your network settings menu. Only at this point, will you have true LTE capability otherwise, you're using a phone with hindered capabilities. Using Telus on 3G is like driving a Corvette with a Cavalier motor.

LOL :laugh: I have already rooted, flashed the Telus ROM and enabled LTE on my device. It is a little more complicated than what you've suggested but yes, you are partially right. Even with the Telus ROM, you need to ensure you've enabled the radio/modem for LTE capability. Thanks for your suggestions!
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?

I have a i9505 running 4.2.2 (UFNB8, DBT CSC) stock, non-rooted. My problem is that I still can't get LTE/WCDMA to display as an available option in Network Mode. Operator is Telenet (MVNO, Belgium). I am in a 4G area, according to the operator my SIM card is 4G capable and my IMEI has been 4G activated. According to them I should be able to connect to the LTE netwrok, but no go. They advised factory reset but I don't want to do that for now as I am not sure it will help. I remember seeing LTE as available when I roam (in roaming my MNC is different though).
Any ideas (apart from rooting and forcing LTE radio on?).
How does the 9505 decide when to turn on the LTE radio? Is it based on getting an LTE signal or is something defined on configuration file level per MCC/MNC...?
Cheers.
OK, I should have searched more. But for future generations' sake, apparently there are two possible reasons:
1. Need a factory reset (still don't understand why?!)
2. Your phone's CSC is not supported on your current carrier's network (apparently this is checked and there's a whitelist of some sort)
In my case it was 1 - I reset and now LTE/WCDMA appears.
Cheers
So i bought a 2nd hand s7 edge off kijiji. No issues with it, but i've been reading that wifi calling is an option with my provider (Bell Canada, hence the BWC csc) and I'm wondering what benefits there are (if any) by changing the CSC in my phone, or if making this change would then enable the option.
I can enter the *#272*IMEI# and get the option to change it, i just want to make sure i'm not gonna mess anything up by doing this.
Any insight would be helpful. Even if there aren't any benefits for doing this change, i'm still curious as to what kinds of things this change can do, whether they be good or bad.
Thanks in advance!
Bump for visibility
I believe all the firmware from any carrier is fine, as long as its from a Canadian Provider.. I bought my Edge from Samsung store... Went onto the Sammobile and flashed a general canadian firmware with the sept update, no issues...
Only way to change the CSC is to root your phone first and then install SAMSUNG INFO software from Google play Use the Csc Changer option and then select your preferred CSC from the list and install then your phone will restart and will restore Factory setting *before doing that make backup your phone* and then your phone will restart with new CSC ......You are done ....
NOTE: this process is only be possible with multi CSC phone or international models
Hello, hoping someone can help out, I bought a AXON 7 mini hoping to use it in Iraq, but it does not seem to want to register on any network outside the USA. In the USA I was using a Tracfone T-Mobile SIM and the phone worked great. As I traveled across Europe the phone would not connect to any networks (Germany and Turkey), I figured it was just the SIM not allowing roaming. When I got to Iraq I purchased a Korek SIM and still no dice. I phone sees two networks but will not show any service. I have tried SIM cards from other phones with active service and still nothing. I have even tried a SIM card from ASIACELL and still no dice, it sees the providers but will not show service on the network. When I click "automatically select network" the phone response "registered on network" but still no service. I have tried the usual reset all the way down to a factory reset.

Phone now seems to be fully functional with aid of a lot of reading an testing. I can also replicate the issue consistently. The original issue seems that the pervious owner, or ZTE set the operating band to "United States." Once this has happened the seems to be locked to USA networks, even though it still sees the other networks. Using *#*#4636#*#* method, you can try to change the band, but only 2 options are there "800 cellular" and "United States," I tried to change to 800 but get the response "unsuccessful." So for the fix!
Thanks to all the hard work here, I was able to install the boot loader unlock update for my phone found here: https://forum.xda-developers.com/axon-7-mini/development/unlock-official-bootloader-unlock-t3690496
I then proceeded to install TWRP, backed up the entire system, and then installed Linage. Then used *#*#4636#*#* and the band now had a third option of "Automatic," selected that and bingo, service in Iraq. Recovered the phone with the backup and the fix stuck. Of point in Lineage there is five options in the band selection, 2 options are duplicates (USA and Auto), I assume for each SIM, and you have to select both autos otherwise only one SIM will work.
This probably could have been fixed with a ROOT application that allows you to enable additional bands, but I was never successful in ROOTing my phone.
