[Q] ATT GS5 + Tmobile Rom + Tmobile SIM + Wifi calling !!! Anyone?!

Hello,
Is there any one using the ATT GS5 on Tmobile network (obviously Tmobile SIM) with wifi calling working ? (Please..please.. I know ATT does not have wifi calling, But if you use a Tmobile Rom with Tmobile sim, you expect to have it working) !!
If yes, would you please share which ROM you are using ? Also if there is a trick to make it wok please share it?
Thanks

no luck so far
This is not a solution, I just wanted to report what I have tried so far.
I have a G900A with a t-mobile SIM card. I called TMO to make sure wifi calling was enabled on my line. I used towelroot + safestrap to install the t-mobile Alliance rom (B4), as well as the latest stock TMO rom. So far, wifi calling does not work. It is always stuck on "Enabling" in the calling options menu. VoLTE doesn't work either, but I wasn't expecting it to. My guess is that there is something in the TMO baseband that makes these things work and that ATT phones don't have.
Any hints and ideas would me much appreciated!

JJ here,
I tried this ROM - [ROM] G900TUVU1BNH5 ported from TMobile, rooted, deodexed, no knox, Download Booster
... everything works, nice and smooth, but the Wifi Calling is stuck "Enabling"...
Same boat.

My att s5 is unlocked and on the tmobile network. Your telling me i can flash the tmobile stock rom? And everything will be working properly, except wifi calling?

Will everything else work properly? I mainly need the t mobile stock rom to enable mobile hotspot, I have an ATT phone and do not wish to trip efuse. Thanks

does anyone know if the same issue will happen with the international version?

On a similar topic, my dad has a AT&T Samsung Galaxy S5 which was sold in Malaysia. And I found out that his phone was not able to hotspot. I have downloaded the official firmware of Samsung Galaxy S5 for Malaysia and was going to use Odin to flash the firmware into his phone. Does that work and not brick the phone? The phone seems to be unlocked as it can be used here except the firmware and the phone is AT&T barnded. Any advise? Thanks

It all works!
Guys, I have some great news. Both wifi calling AND VoLTE now work on my SM-G900A on the T-mobile network. Here is what I did:
I installed the latest ATT firmware (OA1), released earlier this February. OTA update did not work, so I had to flash the original firmware (ANCE) via Odin, and then flash the two subsequent updates using update.zip on the SD Card. This will remove safestrap and root, but fear not.
Once my phone had AO1 installed, I used this tutorial to root the phone again. It invonves temporarily flashing an earlier (ND3) kernel, using TowelRoot, and then reflashing the OA1 kernel
With my OA1 rooted, I installed safestrap. Make sure you install busybox first.
With safestrap, I installed the T-mobile Alliance Rom (build B4).
Seconds after booting, both Wifi Calling and Voice over LTE work!
Enjoy!
Guillaume

Hi Guillaume,
Have you tried just installing the stock T-mobile 5.0 firmware on a Att GS5 ?
I have my GS5 in ND3 rooted and I'm on Tmobile, but the procedure you have seems really long...
I really need wifi calling as I'm travelling a lot and it allows to call my wife when I'm back in France.
Thanks

Thanks as this is great news for us G900A users on TMO! Question though: After 0A1 installed/backedup and Alliance installed, did you use safestrap [TWRP] to restore your data from 0A1 install?

Actually no; I had been using the t-mo alliance rom using safestrap for a long time (just with the old ATT modem and kernel), so I just restored the data associated with that.
Some more info after a day of tests:
You can also install the 5th build of Alliance Rom, it works too
The camera sometimes glitches a bit; toggling HDR on/off fixes it
Except for the camera glitch I'm pretty happy with it!

I might to try to create a flashable zip from the latest t-mobile lollipop release, keeping only the /system files, and see how that goes. This is really a shot in the dark, hoping that the 4.4.4 modem and kernel from ATT somehow work well enough with the t-mobile lollipop rom. Damn you locked bootloader!

Agree with the last expletive.
I did install in alliance B4 in slot 1 of Safestrap and both wi-fi tether and calling worked well. However, my G900A would not reboot or shutdown (dark screen) without a battery pull. After power up...worked?!?!
Did you install as "Stock" or in a slot?
Also have a G870A (Active). Do you know of anyone attempting the 0A1 method and Alliance Rom with the s5 Active?

What would happen if I odin a Stock T-mobile firmware and let T-mobile update it ?
Will it update the Baseband etc ?

I only use the stock slot.
B4 seems a bit more than stable than B5 for some reason. I get some signal issues with B5, and the fingerprint scanner sometimes fails. (It works when I first install B4, use it for a while, and then upgrade to B5. But if I do a /data wipe on B5, these issues appear. I have no idea why).

Okay thanks,
So I started the steps, I've Odin the original firmware and factory reset on but my baseband stayed ND3...
Tried the OTA update hoping that it would work, but as expected it did not.
So I guess I'm at step 1 of your step one.
Then you said you pushed the update via sd card, where did you find the updates ?
Then I'll do the other steps!

They are in the post that I linked to, under the troubleshooting section. If you want to keep your user data, use adb sideload instead of recovery

OK. Installed in stock slot but ROM behaved much differently.
1. Wifi sms/mms work both send/receive but erratically.
2. Outgoing calls connect then immediately drop with local "cancelled" within a few milli-secs with a partial ring at the far end.
3. Can't receive calls at all. TMO network thinks I'm offline even though can receive a text.
3. Phone App GUI stutters when making a call.
4. Camera is basically not usable.
Where there any special steps you took to get this working installed in the stock slot? Has your install remained stable? Thanks in advance.

My phone is still working flawlessly. What your are describing is what happened to me during the short period I reverted to the NG3 kernel in order to use Towelroot. Did you make sure to reflash the OA1 kernel once you were rooted? (before installing safestrap and, within safestrap, installing the Alliance Rom). I have found Alliance B4 to be more stable, so you could try that. Finally, a factory reset (wipe option in safestrap). Beyond that, you could try the whole thing again: flash the "downgrade to NCE" rom, which will remove safestrap and clean everything up; and take the tutorial from there.

Thanks again Guillaume,
Was running OA1 prior to Alliance B3, so just wiped Dalvik and Cache again, rebooted and left phone for the night. By next morning all was well except for the camera HDR issue. Once toggled it is OK until closed and reopened. Haven't had the time to look into whether there are Alliance B4 options which may affect this.
Have run it a few days and have had zero issues with Wi-Fi calling or tethering or apps: a very smooth experience.
Thanks again for your contribution. Also muniz_ri will find a bottle of wine on the doorstep soon. :highfive:

NG2 Baseband unlock without downgrading

First this is only a guide not a repost
NG2 Baseband
1. Use ssu.apk to unlock it first
2.use cf auto root to it
3 use adb:
su
am broadcast -a android.provider.Telephony.SECRET_CODE -d android_secret_code://27663368378
UMTS -> DEBUG SCREEN -> PHONE CONTROL -> NETWORK CONTROL -> GCF
There the phone is domestic unlock without downgrading the modem

Haven't tested this but if it works, Bravo!

@AndroidKing, after doing just pop up domestic sim and go?
how you discovered this? lol
I have not tested yet, but this kill all other methods
thanks,

yea pop the sim and go i found this method when i was nae frimware and baseband and kept updating it went NG2 and lost the unlock for some reason so I tried so this i seen for the note 3/l720t and it worked

So Does this method make my device works on CDMA&GSM carriers (standby),or GSM only carriers?

Thanks for the steps and instruction. Quick question:
- if step 1 (ssu.apk) does the unlock, then why do we need to do steps 2 and on?
Thanks !

I'm not a noob by any means, but I haven't been keeping up with all the s4 updates. I recently broke my s4 witch was running mf9(that tells you how long its been) and the replacement i recieved is OF COURSE ng2. My question is .... will this method root my mk2 s4? Tripping knox doesnt bother me one bit(gotta love blacktie coverage)
Thanks in advance

No this is NOT for rooting
This is only for unlocking. To root the NG2 build you have to use chainefires method which will trip Knox. But you said you don't mind. So root and flash away!

can any confirm?
and, can we get a cleaner instruction for noobs?
also does it matter which ROM u'r using?

ssu step didn't work for me. I'm on NG2.
Edit: It didn't work b/c I was on custom NG2 with custom recovery.
Sent from my SPH-L720

I can't believe it was this easy. I temp flashed back to stock rooted ng2, used ssu.apk to unlock, then restored my GPE Lollipop 5.0.1 backup, popped in my Metro sim(t-mobile), set it to World mode, and bam, says I'm on T-mobile's network, calls and data seem to work. It even shows up as MetroPCS as the active network under status. Put the Sprint sim back in, and it's back to my Ting account.
So to recap, I went to stock NG2 rom, did step one only, skipped the other steps, then went back to custom rom and it now works great. Thanks dude

Stock or stock rooted NG2

I'm slightly confused. Did you root NG2? 1. Stock NG2, 2. SSU.apk, 3. Restore rooted Lollipop?

I responded to your PM. I hope you have time to read a book. lol
For anyone else that's wondering:
1. be on stock NG2. ssu.apk force-closes on aosp/custom roms, at least for me.
2. Run ssu.apk and do the unlock. This does not require root.
3. do the other commands through ADB(step 3 from Androidking's original post), just in case. You may or may not need them. I don't know why it worked for me without them. That step DOES require root.
4. Test your sim card and make sure your phone can read it, and if possible, make a call, try text/data, whatever.
5. Flash to the rom of your choice. I recommend this excellent Lollipop rom by Danvbh: http://forum.xda-developers.com/gal...-5-0google-play-edition-lrx219-12-24-t2982384
It allows easy selection of any band/technology that the phone is capable of(which will not actually mean anything until after this unlock procedure). It also automatically gives you many choices for APN's related to your chosen band(not sure if that is a feature of the rom, or if it is standard Android behavior.) Easily select the correct APN for all sorts of carriers, including many popular prepaid services. No manual entry of info needed(probably).
One thing to note: on the custom rom, when I have my Sprint sim in, it says "Invalid Sim" on the lockscreen. The phone does read the sim though, it just says it doesn't. Not sure why that happens. It may be due to the fact that I deactivated my Ting service and haven't gotten new service elsewhere yet, so it can't actually connect to any 4g lte service. It doesn't do that in the stock rom though, it displays normally. Probably just an odd quirk that will work itself out when I switch services. Nothing to worry about.

I tried terminal emulator and it opens up the secret menu that opens when you dial *#0011# everytime. I couldnt get into it dialing that tho. I cant get it to work in adb for some reason. So I just used this to get into the menu and change everything manually. The only problem I have now is when I flash a lollipop rom, the network mode gets stuck on LTE only. Even if I change it to world mode, when I go back it just goes back to LTE only. Any ideas?

Rooted nexus 6 will not boot up after I edited build prop

Hey all this is my first post on XDA.
So I was trying to unroot and relock my nexus 6 so i decided to replace the build.prop that i have edited with a copy of the original build.prop i had saved on my phone. I used root browser to do this. after I did this I restarted my phone and all I would get is a black screen with google in white and an unlocked lock. it will not boot back up.
My phone will go into recovery mode and that about all i can tell you.
I would truly appreciate your help.

If your bootloader is unlocked, you can fastboot flash the stock factory image.
Or, if you have TWRP Recovery (I sure hope so, since you were modifying the build.prop) you can connect to your PC while in recovery, then transfer a custom ROM .zip from your PC to your SDcard. Then flash it in recovery.

I had the same thing happen, all you need to do is flash the system image only. Luckily you don't need to flash userdata. Still looking for a way to enable tethering.

you do realize that when you edit your build.prop, if you edit to something that doesnt support the n6 or you make a spelling error somewhere, then most likely it will not boot? anyways, the easy way around this is before you edit your build.prop, make a nandroid backup in recovery. so that when you mess up, it won't be a pain in the butt to get everything back.

in your apn, try changing the IPv6 to IPv4 instead, that should fix the tethering issue(not free tethering, just wireless tethering).

Doesn't really matter for me, since I rarely use tethering. But other users may benefit.

Am new at this and in uncharted territory. I rooted my new Google Nexus 6 using the WugFresh, Nexus Root Toolkit 2.0.4, Root program downloaded. Also downloaded Busybox, ES File Explorer, Superuser, TWRP, Root Browser. I fail to understand which one gives me root control. Also loaded Cyanogen Mod 12.1 nightly build as a ROM. Also downloaded Wifi Tether 3.4 Experimental 1-07202013 which has worked in my old rooted Galaxy Nexus since 2013, and previous versions since 2011.
I'm thinking I am in over my head as I attempt to deal with a new system, Lollipop, and now Marshmallow 5.1.1 and new phone Nexus 6 and older tether program? Can you suggest or recommend a ROM with perhaps more compatibility and ease of tethering? Wife and I live deep in country and our phone tether only access we have over Verizon with the repeater.

ZVA update

Anybody get the ZVA Marshmallow update? Did if fix anything?

I have a Sprint G4 LS991 that was already running ZV9 Marshmallow. My phone has informed me today that I have an Android system update. I have no idea what the update is out what it does. Should I install it? What is the version.
. At that does it do?

Already have a theme... Read this.

To allow your phone to use lte plus. I don't know what the effect will be.

I installed this update about 30 minutes ago. Now a bunch of my apps and widgets are no longer installed. I tried restarting my phone and some more apps were updates, but no all. I'm going to try reinstall the missing apps.
My phone is on Software version LS991ZVA and Android security patch level 2013-01-01. I do not remember what security patch level it was before the update.

Any idea about after update zva can we return back to ZV9 or ZV6 ?

Question then. Did you unlock the wifi tether with the ZV6 downgrade trick? If so, does it still work on ZVA? I've got mine set that way but not sure if the ZVA update kills the entire trick.

I was getting two errors consistently: 1) the phone wouldn't sometimes not hang up unless you reset the phone 2) MM texts wouldn't come through properly
Hope those are fixed.

I have not lost wi-fi tether.

My phone got an update 2 nights ago. Shows LS991ZVA now with Android 6.0. The Facebook widgets are gone as well as Facebook seems to be integrated into the software now as you can only Force Close or Disable it. No uninstall options. Not sure how I feel about that. Can anyone else confirm this is what they see?

I have the Sprint G4 LS991 that has been sim unlocked and now using simple mobile. Shortly after getting the phone it updated to MM 6.0. Also lost mobile data. Could not get support from LG or Simple due to imei number is from other. Software version says LS991ZFA. Is it possible to downgrade back to Lollipop 5.1 using the LGUP tool? Also after playing with the APN settings i managed to get the mobile data back on.

You have to change your APN settings. I noticed that this variant of LG G4 likes to auto rewrite MMS settings.
Check to see if it changed from your MMS api settings to a sprint one....

it's an MMS apn setting. I noticed that this phone will try to auto rewrite the APN to default spring settings if a major change occurs.
I use it with t-mobile and noticed it changed on me back to the original after the update. I changed it back to tom's api settings....MMS comes through just fine.

How to change the APN in ZVA 6.0? My IOT shortcut from QuickShortcutMaker does not work. It says "Application is not installed".

That's because you have to open the menu in ZV6, not ZVA. Downgrade to ZV6, open the hidden menu (leaving it in recent apps list), upgrade all the way to ZVA and then go back to that menu. Make APN changes as necessary.

Stupid Oreo... need hotspot back...

I updated my phone yesterday not thinking and knowing they may patch that hotspot hack. I need the hotspot back for work purposes and us you all know that you can't install anything outside network on Enterprise systems. So, the PDANET+ won't help me since it will have to be actually installed on the laptop/device you are trying to get internet access to as well. I didn't want to root my Note 8 but, what options do I have to roll back to nougat 7.1.1 or other alternatives just for my hotspot.

Yes go here: https://forum.xda-developers.com/galaxy-note-8/how-to/guide-sm-n950u-u1-t3685884
First follow 'Flashing Unlocked Firmware: Steps in Post 4' and use (VZW) Verizon - N950U1UEU1AQH9/AQI5/BQK1/BQL2/BRA5
Then following 'Flashing Carrier Firmware: Steps in Post 3' and flash only VZW CSC.

Can anyone confirm if this works? And will we lose vvm and wifi calling by doing this?

Correction to thread title: should read stupid Verizon vs Oreo!

Right... Just frustrating to go through this for hotspot access now.
