Samsung galaxy S5 SM-G900R7 - GSM SUPPORT? - Galaxy S 5 Q&A, Help & Troubleshooting

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.

How about changing baseband version? Is it safe to install baseband version of G900F? Can I change baseband version without changing bootloader?

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

[Q] Help with Modem - Model: WIND (SM-N900W8)

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!

RESOLVED: Enabling LTE on Samsung Galaxy Note 3 (model: SM-N900W8)

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?

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?

Will an S7 Edge (T-Mobile) work on Verizon?

Hello all,
I want to switch to Verizon but I don't have a verizon sim to test my phone, I just got it unlocked through the unlock app. I've also read this post,

Well i live in Mexico, but i own a galaxy s7 edge from tmobile and to try nougat i installed first the Verizon version, and it work well, the only issue was to setting the data configuration, now i use the At&t nougat and everything still even more perfect (the verizon nougat have a lot of little bugs)

Using a Tmobile S7 Edge going to Verizon won't work cause of a few reasons.
1. TMOBILE S7 and S7 edge are not built for CDMA networks that uses certain bands and network. Along with the security of CDMA networks.
2. There is no band 13 on tmobiles S7 and S7 Edge. Even you were to unlock it.
But going from CDMA to GSM most phones work due most of the hardware and software is already built in the phone.

I can confirm this. Yes, your unlocked T-mobile S7/Edge will work with Verizon network if you flash the U firmware. I'm currently using my unlocked T-mobile S7 Edge with the U-firmware on the Verizon network. Voice, text, data work fine. No issues for me.

You can flash the stock Tmobile ROM or the U firmware. The only reason I got a new S7 when I jumped from big red was I had a huge scratch on my screen. I was running the U firmware when I went into tmobile and used the girls sim card from her phone to prove I could do it...

You need to UNLOCK your phone. It might be a Tmobile phone and running G935U software...but the sim is still locked to T-Mobile. Here is Tmobile unlock page information. you can request unlock in the T-mobile app or by calling T-Mobile....then it should see the Verizon sim and load up just fine once the phone itself is not locked to T-Mobile only sims. https://support.t-mobile.com/docs/DOC-1588
And for anyone else looking at this forum, There is no physical difference in hardware from a SM-G935T phone and a SM-G935U phone. Samsung actually made the hardware the same for all US Variants it is just the software that is different. And not that you would want too but you could load other carriers software on your phone if you wanted too(IE- running Verizon software on a SM-G935T, or ATT or SM-G935U (Stock Samsung Software) The only problem Running SM-G935U is they haven't upgraded the unlocked us phones to 7.0 yet. Where T-Mobile and other carriers already have nougat out.
The SM-G935U software however has all the US and even some Chinese LTE bandwidths enabled, and it also enabled the CDMA bandwidths to be used on the SM-G935 phones...hence why it will work with Verizon, Sprint, and even US Cellular if you can get them to put it on the account.*(I haven't dealt with US Cellular in years and with the new laws on moving phones from carrier to carrier in the US they might not have any issue with Bring your own phone to US Cellular anymore I do not know!)

I can confirm this. Yes, your unlocked T-mobile S7/Edge will work with Verizon network if you flash the U firmware. I'm currently using my unlocked T-mobile S7 Edge with the U-firmware on the Verizon network. Voice, text, data work fine. No issues for me.

Had you flash any ROM before via Odin?. If so, you will only need to download the verizon firmware (sammobile.com) and flash those files. if not > Open odin (Attached) load all the files accordingly (AP, BL, CP, CSC) in ODIN> put your phone download mode ( pressing fingerprint button + volume down + power) > connect phone to PC > Once all files are ready in ODIN hit start. You will get the success message and phone will boot.

Exit completely ODIN (make sure you run it as administrator), repeat the process and make sure all files are uploaded (AP takes a long time to upload) make sure to use the CSC file label as HOME_CSC. Try to flash again.

Does the phone have to be unlocked before adding these files or does it matter?

If you are going to use a verizon sim, you will need to have it unlocked. Firmware flash won't sim unlock/lock the phone.

Thanks for the quick reply. I thought I was gonna be waiting months. I got it tho. The home csc file wasn't working so I used the other one that reset the phone to stock. It was g935u firmware for tracfone from T-Mobile if that helps anyone in the future.

Great it worked.
I flashed the tracfone rom and everything is working well. I got a software update notification. Should ignore it or is it ok to update?
Bumping the thread...sorry guys. I just jumped ship from Verizon and went to Tmobile today with my S7 Edge along with my wifes S7 Edge. Can I flash her phone with the U firm from TMobile and is the U firmware from tmobile the same U firm that is provided to Verizon? Jist wondering. I've used Odin plenty and understand flash process.

How to Full carrier unlock Verizon S8+ with Stock SM-g955u1 bloat free

DISCLAMER: I AM NOT A DEVOLPER AND MAY NOT BE ABLE TO HELP YOU ON YOU DEVICE. UNSUCCESSFUL ATTEMPTS TO FLASH FIRMWARE ON THIS DEVICE CAN AND WILL BRICK YOUR PHONE. BACK UP EVERYTHING IN EVRY CONCIEVABLE WAY.
After days of trying to do this with all the outdated guides and miscommunications and edits in post i decided to try and make a streamlined guide to help others.
NOTE: If your are looking for anything else other than a stock bloat free unlocked firmware then look elsewhere.
Also if you are using rev 1 booloader then this will ireversablly upgrade you to rev 2 bootloader not a real problem just a note
Download 3B's patched Odin 3.13 https://drive.google.com/file/d/17wH1YHcGsOCxbDGYDoy9VlnqO_Xi6IOm/view?usp=drivesdk
Download samfirm.exe
https://drive.google.com/file/d/1XdboeTqk8pSZyJQVt-IHVHFfznJ9eOQk/view?usp=drivesdk
Thanks to @zxz0O0
If you can't find your own drivers don't do this
1. Extract B3 Odin
2. Extract and run samfirm.exe
3. Make sure auto is checked use SM-G955u1 as model number and XAA as country code then search. It should find you the absolute latest firmware
Hit download and choose file destination. This can take a while.
4. extract firmware.zip
5. Run 3B's Odin and add file to there respective locations. I.e. Ap file in Ap slot etc. Use the non home CDC
6. The only thing you need ticked in Odin are already set by default
7. Boot phone into download mode power+bixby+volume down while the device is off
8. Read the screen that pops up very carefully and decide to continue at you own risk by pressing volume up
9. Connect phone via USB 2.0 port do not use a USB 3.0 port it will not work
Make sure Odin recognizes device if it doesn't then u have a driver issue
10. Press start and wait patiently
11. Phone will reboot it self setup device and insert sim card. You will probably get a notification say phone not allowed a quick call to the service provider you trying to use is all that's in order here
12. Enjoy your carrier unlocked stock SM-G955u1 on your preferred network
I AM NOT RESPOSIBLE FOR ANYTHING YOU DO TO YOUR OWN DEVICE YOU WERE WARNED.
So this gets rid of all bloatware?
From my knowledge, Verizon does not, and has not ever carrier locked their phones. Seems like a lot of trouble just to debloat.. Am I missing something here?
Any idea why it stucks at "SetupConnection.."
This worked GREAT! My Verizon S8+was working fine on AT&T before I did this, but I was stuck on Android 7.0. So thank you so much for this. There's only one thing that bothers me is in my drop down menu there's a notification that says "Sprint OMADM Checking Device Status." Which really isn't a big deal, it's just annoying. Another thing I worry about is, i'm using it on a GSM network, is it actively searching for a CDMA network at the same time and draining my battery? Any input would be appreciated, and thank you again!
I have a verizon s8 plus does this still work please confirm???

The method will be similar just need the proper firmwares for your device
This being quite an old post I was wondering ...
I am currently on G950USQS5CSB1 with CSC XAS/XAA/VZW.
Currently I have no carrier bloat (good), I am on Mint with no issues (good) and I get prompt OTA's I assume for carrier VZW but I lack wifi calling which I would like (bad).
I have downloaded G950U1UES5CSB2 for G950U1
Will this work using the 3B modded Odin as described without having to flash the combination files?
normal and Prince Comsy Odin both failed.
Thanks
edit: Took the dive .... worked great thanks, now on G950U1 and have wifi calling and VoLTE
This is great, minus one thing, it installed facebook on my phone, which I didn't have before and never wanted and it won't let me uninstall it..
I'm hoping you are still monitoring this old thread. I have a Verizon Galaxy S8 and followed your instructions exactly (except that I downloaded the files for SM-G950U1 (my current model is SM-G950U). When I start Odin, it gets stuck at "SetupConnection" and never goes any further. Thoughts?

Yea. I just switched to Verizon. You should be able to just pop your sim in and it automatically carrier switch. Most of these are multi carrier
But yea I don't know about the firmware program he's offering never used it I get mi e from sammobile.com or update.com

Yes, it has unlocked as it recognizes my sim card and carrier. But no signal. I think the problem is the device is with "MIPI device fail" status

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

Yea not yet. I'm also on 7. We need edl files first. I got the combination rom for the boot img but edl is still missing. I got a few guys looking for it. I typed in the error you gave me and saw a few sites with no box fixes. Normally if you can get to the menu I don't see root being needed. But I may ne wrong since I've never seen this error
This would be great if it worked. However I have my doubts. You would first need to have the phone be from Verizon or be on another carrier and *unlocked* first before changing any CSC using the US OPEN firmware which allows you to simply put a sim card in and switch carriers by swapping sims and letting Samsung reconfigure the phone. The BEST setup is a SPRINT phone.. unlocked.. then converting to U / U1 firmware. You then have every possibility when it comes to carriers sitting at your finger tips!
Good Luck

Your post dont even make sense. The Verizon s8 at the time came sim unlocked. All you had to do was swap the csc. But worked unlocked out of the box. Why would a sprint device be the best setup. All the us s8s are identical. Sounds like you come from LG which is true on devices and versatility. Not Samsung.

How to remove write protection Galaxy S4 SGH-i337 (hardware), containing i9500 firmware?

I purchased an SGH-i337 motherboard from Ali Express. However it is booting into an [email protected] stock i9500 ROM with Android 4.2.2 on it. I tried to flash it using Odin 3.09 with the corresponding SGH i337M stock ROM of the 5.0.1 Android but getting <ID:0/013> FAIL! (Auth) message. Also in download mode on the top left on the screen it shows one grayed out line saying "write protection enabled". So, I assume its the write protection giving me this problem. Perhaps someone has an idea how to enable writing to the device?
Thanks in advance
Lutz
AT&T never sold the I9500. If the motherboard is an AT&T model - a quick trip into download mode will confirm that - then your best option is to get your money back. AT&T locks the bootloader, meaning you cannot change the ROM.

Thank you. Well I got this main board for cheap and for the purpose of playing around, experimenting with rooting etc. What struck me was that the board is an i337 (which also is confirmed when going in download mode) but contains a well running i9500 firmware. I wonder if someone ever here has come across such oddity. Perhaps it is a chinese trick to re-sell old main boards, who knows... So, what you are saying is that it is bricked already and there is no way to ever download a different OS? Also of the bat, my Canadian SIM card will not work - which points clearly to a locked ATT firmware. I heard about a possible way with enabling debug mode to turn off the write lock, not sure though if that is applicable here...
Frequently. Resellers would buy the boards from phones with bad IMEIs in the US and, using hardware that worked with contact points on the board, rewrite the firmware without touching the bootloader and change the IMEI as well.
We usually tell people who get such a motherboard to get their money back. Now...if you want a North American motherboard that can be modded, you want a SGH-I337M or a SGH-M919 board as both of them have LTE that works in the US and have unlocked bootloaders.
Thank you again. I think I have learned something... So, the resellers just rig the board by somehow enabling to write firmware to the NAND flash bypassing the boot loader? I thought the IMEI is absolutely untouchable, but as you say apparently not so if you know the exact location in memory and know how to override perhaps? Darn, I thought I could practice with this board a bit until using my "good phone" for going to LineageOS. Well I will leave a rant on this seller at least.
Essentially yes. It used to be that changing the IMEI wasn't necessary, but if I recall correctly IMEI blacklists are now global in scope, so a phone IMEI that is blocked in one country would be blocked in others.
On Android 4.2.2 the IMEI was stored in a directory in the device internal storage and could be easily lost. Around Android 4.3 or 4.4.4 that file was moved into a portion of the device storage that normally is not user-accessible.

I have been trying to root this thing using jortex method with the exploits. This failed as literally every memory address this program tried to access was readonly. I am just running this board on a display and the USB connection, which should not be the problem.
Also curiously, on this board I can't get any SIM card to give me access to a network operator. Searching for operators fails with a brief error message. Otherwise it seems okay reading my phone number and showing it. There is no apparent network lock present. So, this piece of hardware really puzzeles me. It seems bricked if I can't even use my SIM card, let alone the write protection to everything. I already complained, but what can you do with these AliExpress Chinese dealers. He tried to explain to me how I can lock a SD card - totally off, - or avoiding the topic.
Unless things have changed, you have to use Safestrap recovery on an AT&T board to be able to do anything with it, including root it. With Safestrap you can install a second copy of the firmware on the internal storage and root it. You'll need to search the AT&T S4 forum for more information.
