Help To bypass tethering block - Galaxy S 4 Q&A, Help & Troubleshooting

Hi
Just brought my Mrs, A Tab 4 Wifi edition. I want to see if it is possible to bypass the three network block on tethering.
Just recently updated the Samsung S4 to lollipop.
What i would like to use is the phone as hotspot or internet sharing for the tablet.
i hope somebody has some ideas or has been able to do this.
thank you.

I don't think the operator can even see that you are tethering to your tablet.

I've tried every route possible, creating a wifi ir bluetooth hotspot,but not possible. Get message saying I cannot tether, need to purchase a add-on.
No add on available until I upgarde.
update: just tried her sim card in my s5 which is running Phoenix Rom, tethering working fine no message nothing.
she is running stock rooted android.

It's likely the firmware was customized by Three to remove tethering. Your options?
1. Root and install a custom ROM.
2. Install the BTU Samsung firmware for the S4. BTU has no carrier branding or modifications.

I don't think changing the rom is a option coz she doesn't want to lose all her photos messages etc. Baiscally she has already TOLD me I'm not allowed to do that.
Is there anything possible I can do without changing the rom.

Unless you want to pay for the tethering, there's no way I can think of other than changing ROMs.

You know you can back them up? And even so, if you flash a custom rom, then you won't wipe the photos.

Yea I know I can back them up and stuff it take some time though. You wonder if there was a work around like a exposed or hack or something.

Cross ROM Flashing

I am trying to find solid answers on this before I do it, but can't find any evidence it will work, and without issue. I just want to gain my T-Mobile wifi calling, and be able to use IPv6, but the ROM that my Note 3 came with, does not allow any of this (APN protocol is perma-greyed out and of course no wifi calling).
So here's what I have: Mexican N900W8
The ROM I want to flash: N900T for T-Mobile. Stock ROM.
Can I just simply use Odin and just flash it without rooting or anything since both are stock ROMs? Or do I still need to root it?
Also, if it will just flash right over, will my phone identify itself as a N900T and get over the air updates for T-Mobile, or will it ID itself as a N900W8 still, and possibly have future update problems?
Lastly, will all the other hardware work fine without issue? Wifi (most important obviously), NFC, etc?
Thanks.
I tried looking for this kind of cross flash but could not find anything whatsoever concrete that re-assures me this will work.
I would really like an answer for this.
Can I cross flash a stock ROM or not, and in this case N900T to N900W8 without any wifi issues?

You can flash 900T ROMS on the W8, however, not via Odin. Has to be done via Custom Recovery and you still have to flash the W8 kernel for it to work. - Essentially yes, You have to root, but I don't think you can get your T-Mobile WiFi calling unless you have an actual N900T.

As radical said, you can flash it using custom recovery.
It will show up as N900T instead of N900W8, but you can change this using "build prop editor" from the Play Store.
You will not get any OTA from T-mobile, custom ROMs don't get official OTAs.
I went and got a N900T then from T-Mobile. Have a N900W8 for sale now.

[Q] installing Tmobile rom to i337

Hi,
Currently I have a i337 galaxy s4 which I am using with tmobile sim card. I made it unlocked by ATT before I switched to tmobile. It has baseband UFNI1 and Android 4.4.2 installed. I managed to get it rooted using the Odin software, so I can use the tethering with the tmobile.
Now I am trying to find a way to use the Wi-Fi calling. I searched it a lot and figured out that I need a tmobile rom installed but it quickly got very confusing. It looks like what you need to do also depends on what android version you are using. For some you need safestrap, change the kernel for some you don't. For some you have Wi-Fi issues and need to change the modem etc.
So, I am trying to find the easiest and safest way that will make the Wi-Fi calling work. I don't necessarily need the very latest android version or the fancy custom roms etc,I only need something that will work without any issues. I am perfectly fine with a tmobile stock Rom if that's the most convenient way.
So,I would really appreciate if someone can help me on this. It would be great to have a set of noob friendly instructions. Thanks a lot.

Hi There,
Were you able to root your device for Wifi Calling. I followed the instructions of http://forum.xda-developers.com/gal...nvert-i337-to-m919-wifi-caling-t2896719/page6 and went into the same issue. After TMOBILE stock rom, the phone does not boot. I was able to install the first rom and then able to get onto the latest version and able to use phone again with AT&T latest software update (android 5.0.1). Actually, this is the version I have when I started rooting.
If you find any solution, please let me know as I am on the same boat with you on installing TMOBILE ROM using the other thread.
thanks

You cannot install a T-Mobile stock ROM to an AT&T device. Samsung has safeguards in place to prevent it. You would need to root and then install a custom ROM, which on an AT&T is difficult to do with its encrypted bootloader.
However, this is not the appropriate location to ask this. Questions related to AT&T devices belong in the AT&T S4 forums.

Sm-g950w questions

Just a couple of questions. I havent flashed a custom rom in a long time. Last time was on a galaxy note 3, and I tripped knox. Was a pain in the butt and I could no longer get my banking app to work properly. So I want to make sure I dont do that again. Ultimately I want to get my bluetooth tether option back (i had it on android nougat). My watch only has bluetooth and needs bluetooth tether to access the internet.
My first question is will installing another firmware give me that option back.
Second question is, if I flash another firmware with odin, will it trip knox.
Third question, can I flash us firmwares.
Fourth question, is there another way to get bluetooth tether back without flashing another firmware.
Sorry if these have been answered before, but a google search didnt yield any answers, as well as a search on xda.
Edit: Well I tried several other canadian firmwares, but ultimately, they still installed the Rogers crap bloat, and also didn't enable bluetooth tethering. I heard sprints firmware might have it enabled, but I'm not sure it will work with my phone. I guess my only questions that remain, would be if I can flash a us firmware to this phone, or if there's another way to get my bluetooth tethering back.

Flashing unlocked Samsung S10+ to T-Mobile Firmware

Hey guys, first time on this forum and I am trying to figure things out. I never flashed a firmware so im a noob to this, but I can definitely follow along. Here is my main concern:
Seems like you need a T-Mobile device to get access to features like advanced messaging, visual voicemail, wifi calling, etc. Things I use all the time, but I never knew it would be taken away if I purchased an unlocked S10 plus.
My main goal is to get these features back, which from what I understand requires flashing the firmware? If there is any other way I am more than open to listen to it!
I have Odin and downloaded the "userdata" linked into this post: https://forum.xda-developers.com/galaxy-s10/how-to/g975u-g975u1-firmware-links-t3905897 specifically USERDATA_TMB_G975USQU1ASAT_CL15296297_QB21819666_REV00_user_low_ship_MULTI_CERT.zip
I figure I unzip to get the tar file, select Odin use data and only flash this file? Kinda clueless about all this.
In addition, if I were to flash I hope that Samsung Pay, Knox, finance apps will still work; also the warranty is still good. I know that rooting the device will/may make these unusable, but I just want to confirm.
Any guidance is greatly appreciated, thanks!

WiFi Calling, VoLTE are working just fine, but I get what you mean... I mostly flashed 4 firmware files: BL, AP, CL and CSC and couple of times did flash USERDATA too. As userdata file was not required to be flashed unless you want all bloatware from the carrier. Don't know if S10 needs this "userdata" file. You would want to flash I mentioned and specifically flash CSC file and not the HOME CSC(as it usually retains user data on your phone) and in your case you want odin to wipe the device. I want to flash too, but waiting for firmware to become available on sammobile website

Basically I should wait for Sammobile to upload those 4 firmware files (BL,AP,CL,CSC) and then use Odin to flash the firmware. Seems the instructions for that are really easy.
As far as the Samsung pay / finance apps, would it mess those up like rooting the device?

There should be no issue with Samsung Pay and other apps, as you would be flashing official Samsung firmware. Wait for firmware files to be available and then you would be able to see which files will be included and go from there. On my unlocked S8, I didn't flash userdata file and still had all T-Mobile features you were mentioning. If with S10 we will have the same, then skipping userdata is better as the device is pretty much clean without unneeded apps
I installed T-Mobile's Visual Voicemail app from Play Store, and it works just fine. (Unlocked S10)
I did the same. Figured if I was paying outright might as well get an unlocked device. But the Samsung's from tmobile have the multi line function and I'm trying to get rid of my iPhone. But I use that number alot as well. So that multi line function built in for DIGITS worked for me. If you flash it let me know if it has it built in

Wait. How did you get the multi line functioning on the s10? I have been scouring the internet for a solution
Curious, are there any features/capabilities that the unlocked version has, but the TMobile version does not? I ordered an unlocked S10+ (haven't received it yet) and TMobile is my carrier.
From what I've read so far, built-in caller ID, and the ability to turn mobile data off, are not on the TMobile variant, but I can't confirm that.

I don't. I have the unlocked version. But I have tmobile. Didn't think about it until I received my device. So If flashing the tmobile software will give it to me i will flash it.

Thanks for the info too! I am also quite curious about this as I have an unlocked S10+ still pre-ordered. Unfortunately, it's too late for me to cancel it and re-ordering it on T-Mobile before April comes around as I would like to use the phone on my travels by then (still hanging on to my S5 at the moment... lol).
From what I've read, the two major features lost on unlocked phones are EVS and RCS messaging. While RCS messaging is something I can live without, I would really like to keep the EVS (Enhanced Voice Service) feature usable on the phone when it arrives.
One other question, are you able to get the updates via T-Mobile on the flashed firmware or does it have to be flashed again for future updates?

What is EVS? Is that just another term for VoLTE?

VoLTE and EVS are different. EVS is an evolution of the AMR-WB speech codec (aka HD Voice) whereas VoLTE uses said speech codecs to work. VoLTE is currently recommended to use at least AMR-WB for good voice quality. As EVS is the newer speech codec that uses similar concepts to that of AMR-WB, it is backwards compatible with technologies already using AMR-WB, which includes VoLTE.
That is what I can gather, feel free to correct me if I am wrong in any of the details.
Thanks to all for their insight. Just an update:
I flashed the T-Mo firmware on my unlocked S10+. It worked - RCS and video calling are back! However I noticed 3 things: 1st I used the CSC, but it did not delete all my apps. 2nd when the device rebooted after flashing it went into recovery mode (is this normal?), but i re-rebooted it and it went right into my phone.
3rd while RCS is working on the phone and between my Android 8.0 Note8 Tmo phone, the Note8 cannot send pictures/files to my S10+. The S10+ can send anything to me, but not the other way around. Read, Delivered, typing indicators work. I am not too concerned about this as I am getting an S10+ myself next week so this will not be an issue.
Any thoughts about that?
Other than the RCS thing, the S10+ device is working completely normally. I heard you have to change the CSC on the device but I did not do that (echo, adb, and all that jazz) - is that necessary as well?
Lots of random thoughts over here!

Would you be able to help walk me through the process to do this. I used to root and flash custom roms to phones but the carrier specific and Samsung stuff is new to me. I'm interested in getting on the TMO firmware possibly for RCS but I don't know if it's worth the hassle for it yet

Thanks for that update.
By any chance, could you let us know if the built in VVM is working? (accessed from the dialer by tapping the 3-dot menu button ((from within Dialer)). You should see Visual Voicemail as an option, not just Voicemail.
I flashed the TMo firmware as well, but used Home_CSC. That didn't seem to matter, since Userdata wipes the phone anyways, but I'm curious as to whether that is why I am not seeing Visual Voicemail.
As for the booting into recovery, did you have the reboot option checked in Odin when you started the flash? Mine has booted to recovery before, but it has always been because I forgot to check that box.

So I have another update about this. When I included the userdata in Odin it reset my device. The visual voicemail is not working still, and i can't confirm (or i dont know how to confirm) if wifi calling or VoLTE is working as there isn't any real indication on the device. But all my RCS problems have been fixed!
...Except that all my MMS contains the "Subject: No Subject" header on every single MMS. Every. Single. One. I had to change my default messages app because this was just too damn annoying.
and yeah, i did check the box.

Is there a voicemail icon in the dialer after flashing? Or it's still not there?

WiFi calling option is within the phone app settings itself, and it would word even without flashing tmo

No. This does not trip knox, nor will it void your warranty. Tampering such as flashing unofficial software will incr the Knox counter. This matters because technicians inspect the software state (among other things during checkups).
Assuming they actually verify it, the device will fail this step (not the case when using signed packages from Samsung for conversion!). .

I spoke with a Samsung care rep on their website, who told me it will void the warranty. But then again, most customer care reps dont actually know what their talking about beyond the basic questions...
