Hi Guys,
I have installed the XtreStoLite rom on my Bell 900W8 but for some reason it shows up as 900T. Is this normal? Everything seems to be working fine the only complaint I have is that my reception doesn't seem to be that great. On my previous S4 it seemed better.
I've also flashed the proper bootloader and modem as detailed in the OPs post #4.
PS - I'm posting here because I don't have sufficient privilege to post in that Rom's thread.
Probably because your custom ROM was based on a 900T. It's normal for various custom ROMs to show up as another model. e.g. if you install the Phoenix ROM it will show as 900F regardless of whether your phone was originally a 900W8, 900T, 900F, etc.
It doesn't affect much and most people wouldn't be worried about it. If it bothers you for some reason you can edit build.prop to make it show 900W8 or whatever you want.

Hi all,
I just sim unlock my sprint s4 both international and domestic. It come with the NAE modem. while unlcok it, I odin to MDC modem.
I have signal and text on AT&T network on this phone now. ( Phone is not rooted yet, I did edit the build.prop to add ril.sales_code=LOL
ro.csc.sales_code=LOL. I am not sure if not-rooted matters).
Right now I am looking into flashing a rom to use on AT&T network. Lots people suggests Fenny's T-mobile rom. and some suggest SACS CUSTOM ROM
I am not sure which is better if I am using a GSM network.
And If T-mobile roms are better for GSM rom, how could I flash them? Do I need to flash NAE modem back?
Thank you for all of you idea/suggestion.
I just asked pretty much the same question in the following post...
http://forum.xda-developers.com/showthread.php?t=2764201
I think we have to build the roms for the device ourselves, but I was reading about calling issues on unlocked phones so I'm trying to find out what to do as well. Flashing recovery is easy enough, then the rom of course, but getting this right rom zip seems to be a little tricky in our scenario. Not hijacking or anything, but check my thread too in case someone answers on mine first.
BTW, this is the post I was referring to about phone issues with non-stock roms on an unlocked sprint s4...

Well, it looks like the 100% sure way to get this working is to do the outlined steps in the post linked above to the nightly builds of CM11, which I will link below (notice the spr/att designation at the end of the link)...
http://download.cyanogenmod.org/?device=jfltespr
http://download.cyanogenmod.org/?device=jflteatt
Other way looks to grab a jflteatt labeled rom from the Sprint Android dev subforum, but it looks more hit or miss. I might be way off and overthinking this, but I'm gonna try the mix/match way.
Well, I ended up working this out myself. I grabbed the nightly CM11 spr and att jflte builds, then followed the directions from the post I linked before that showed how to mix the 2 so the Sprint boot.img was in the AT&T build, including changing the updater-script so that the assert line read "jfltespr" in the 3 locations it had "jflteatt", then flashed the jfltespr CWM recovery from Heimdall, used recovery to wipe data/cache/darvik, installed the mixed rom from recovery, then installed the Chronic kernel (blackscreen without this), and the gapps apk for CM11. Once I was done everything worked perfectly, I only had to change the APN to the ATT Phone one for HSPA+. From what I can tell the CDMA portion of the phone is pretty much gone, and it shows the phone model as the AT&T version instead of the Sprint version (ie shows l337 instead of l720). The correct phone number from the SIM is now properly displayed as well. Also, with the Chronic kernel (slight OC) and CM11 the phone is lightning fast and responds instantly. Overall I'm very happy with this. Hope this helps anyone else in the same scenario. BTW, still using MDC modem from Odin flash during the domestic unlock.
Hey everyone,
Please bare with me, this is my first time rooting & flashing a smartphone, so my knowledge on the topic is still limited even after some reads.
I also have the "misfortune" to not fall into the (apparent) easier route of having a non-Canadian Galaxy S4 where the model starts with "i950.." but mine being SGM-i337m. From what I've understood, the only reliable method I could use would be CF-Root, as described in this thread (OP's post), although the thing that bugs me, because I'd like to be able to install whatever ROM I'd like, is the line that says "[..] and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares [..]".
Also, which might be worth mentioning, my best bet is I'll probably end up flashing Cyanogenmod's ROM and they seem to have packaged installers, but I'm still worried it might not cover my model (if I take that route instead of rooting using CF-Root). From CGM's wiki under Supported Devices, there's a list that includes "jfltecan" (code name) for Canada, but I'm still hesitant. Do you guys think it covers Koodo (service provider) which I believe is owned by Telus (another SP) ? The last thing I want to do is brick my phone or have it unusable at the booting stage or whatever. And I don't mind reading, so any helpful links which covers this specifically would much be appreciated, although I don't mind an all cooked answer
Thanks
Will the i9505 stuff work on the SPH-L720T? It's the branded Sprint version of the i9505 and I don't want to brick the damn thing. If there is anything I need to know, now would be a good time to tell me. I will point out that I have the 4G version (I think that's the only version made for this model anyway) and it is unlocked to work on all networks. Will I loose that if I flash a custom ROM?
Secondly, I am looking for a ROM that is as close to the stock experience as possible but doesn't have all the issues of stock! But with fixed stagefright issues, the widget draw on Touchwiz UI, and better power saving features.
Thirdly, recovery: what is the best one to use? I was thinking TWRP since I already have experience with that. Do I also need to match up an Odin version for my device?
I think that's about it for now. Thank's for the help!
If the code was jfltexx, it's safe to flash. Just check the ROM's thread for any special guides if available.
For stock-based, no idea. I don't have an I9505.
Sent from my GT-I9500
Thanks. Where do I find the code to tell?
On any I9505 development thread with jfltexx on their supported device list.
Sent from my GT-I9500
It's a rebranded I9505. They have identical hardware.
Your phone has a tri-band something. I don't know what it does, but it seems to be carrier related. That's the only difference between the normal SPH-L720, I9505 and your model.
Ok I'm just a little confused.
Canadian i337m compatible marshmallow roms?
Are they jflteatt jfltexx i9505 or something else or all of the above.
(I'm running wamanlite 4.4.2 9505 rom now on my jfltecan I don't think there are any good links for it left, and when I flash a new one there will be no going back)
I know there are others confused out there as well..
If you are using marshmallow and you have flashed the rom to your Canadian s4 and all is working great.
Please post a link to that rom here
If you needed some other kernel or file to flash in to make it work
Please post that info with links also.
Thanks for any info you can provide.
(And bite me Samsung att and others for locking so many U.S. carrier boot loaders which has reduced development)
The s4 should work with the 9505, jflteatt, and jfltexx ROMs; however, editing the updater script may be required to get the ROM to install.
Hahaha - you will likely get yelled at to use the search bar and to read the stickies with these sorts of questions, but I was a noob once too, so here's an olive branch. (that being said, please do use these in the future!)
Your i337m will be cross-compatible with ALL GS4 devices (at least to my knowledge). I've had one now for a little over 4 months and have explored most of the options available to the Canadian variant. I have run everything from 4.2.2 to 5.1.1 on my device successfully, but you will have the most luck where the developer indicates that the build is for jflte devices in general, not one in particular.
Furthermore, the GS4 or ANY device sporting a Qualcomm chipset can use a modified modem file to access WCDMA/HSPA bands (ie. WIND, or T-Mobile).
Again, the search bar is your friend here! Also try Google, or Duckduckgo (google will tailor your results, sometimes in a way which will actually hinder your search).
If all else fails, send me a PM and I will assist you wherever possible.
Best of luck!

Just wondering what modem to use. Do I use the latest modem for I337M or can I use modem for I9505. I live in Canada and have always used the modems for the I337M model. The latest modem is PA1, I think for the I9505.
Hey tvsite,
Modems for this phone in Canada puzzled me for quite some time, however, this is what I did to make things work.
--> Downgraded from 5.1.1 CM 12.1 Optimized via odin using "I337MVLUAMDJ_I337MOYAAMDJ_VMC.zip" (http://www.sammobile.com/firmwares/download/14412/I337MVLUAMDJ_I337MOYAAMDJ_VMC/)to net me 4.2.2 (note: your wifi or calling WILL NOT WORK).
You may have even better luck using the SaskTel firmware at this point, although I have not tried it yet. (http://www.sammobile.com/firmwares/download/14418/I337MVLUAMDJ_I337MOYAAMDJ_BWA/)
--> Do the AWS mod, unlocking etc.
--> Upgraded to 4.4.1 using "I337MVLUFNC1_880525_REV06_user_low_ship_MULTI.tar"
https://mega.co.nz/#!h8pTnCZS!t2-PiSb5W9ZyNp7fct7WD_Pg_dnc-eZqtMvpsuKv_9Q
--> I forget what modem I was on at this point, however, after letting OTA do its thing, I wound up at 5.0.1, OH1 modem, and AWS still enabled.
Good luck!

I flashed the OK1 modem which is posted, here, which is for the I337M model. I believe this is country code Mexico. This modem is working fine. Have you tried flashing a I9505 modem using Odin. I tried and it said "failed", so I may have answered my own question---that you cannot flash modems over different model numbers even though its the same phone, ie. S4
Hi,
I have a G900F I got in the UK and I've just moved to Canada with. Problem is it doesn't support some of the bands here so I find I often have a poor signal. I'm happy with the stock ROM but I believe if I am to open it up for all bands I need a custom ROM.
I don't need anything too flashy, but I'd like everything to work and be responsive.
In terms of the most complete ROMs it seems LineageOS Official and Resurrection Remixed are the most popular. Can anyone comment? How about Android 6 vs 7?
Thanks
Used to use resurrection but now that I've moved to lineage os I can say that its better and getting improved every update it gets

g900f is almost identical if not the exact same as the canadian s5 g900w8.
you would need to use correct freq for your carrier, search will provide a howto. worse case scenario is to flash a canadian 6.0.1 modem from any canadian 6.0.1 stock fw
if trying to figure out connectivity, stay w/stock first as modems are from stock fw.
imo try superlite 6.0.1, it stock based and only takes a few minutes to install that way you can test out your carrier connectivity issues
https://forum.xda-developers.com/ga...-superlite-mini-mm-v1-0-361mb-g900w8-t3497158
So I can keep my stock firmware and just replace the G900F baseband (G900FXXS1CQAV) with the Bell Canada SM-G900W8 Modem and everything will be the same except the phone will work on the Bell Canada frequencies?
I had been planning to follow this guide: https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059 to enable the 1700MHz band which is disabled on the G900F, but if flashing a Canadian modem will enable this band that sounds easiest.
Do I need to download the full 1.5GB firmware and extract the modem from it?
Thanks

ive never tried flashing a mdm from another model as ive never needed to for the s5.
ive not read enough to know if its possible or if it has any neg consequences.
easiest would be to change freq w/current mdm, search for samsung secret service codes to view and maybe change current freq
good place to start is here https://forum.xda-developers.com/showthread.php?t=2729694
I've done a lot of research on this forum. Most people say that installing G900W8 firmware on G900F isn't possible. Also it seems that it is the NVRAM which stores what bands are allowed on what model, so simply flashing a different modem won't make a difference.
Some people are saying that the hardware is different and this is what limits the bands, but I don't believe so, the radio/modem chip is the same version between models.
Trying to follow the link I posted earlier to change the NVRAM values after installing a custom ROM appears to be the only way. Some people say it works, and others say it only appears to work. The original thread was closed years ago so I guess I'll just need to try it and see.
Alternatively I could buy 2 phones, one W8 to use in Canada and a F to use in Europe, this seems silly though.
