[HACK] T-Mobile Users: Enable Volte(B12) on Mi Mix - Xiaomi Mi MIX Questions & Answers

Thinking about picking up a Mi Mix to use on T-Mobile (found a good price for one)
To the brave could you give this a go and let me know if this enables B12/VOLTE coverage on your device.
I'm aware of only 2 and 4 working. To anyone in Philadelphia what kind of speeds are you getting?
I know in some cases T-Mobile has to certify/sign off on a device for support but some unlocked/foreign devices I've use have work without T-Mobile having knowledge of it.
Below are some steps to those that are rooted; Give this a go and let me know below if it works or not.
Thanks

I'm currently on EU 6.11.0 and it has VoLTE enabled by default but no B12 as my office is in the basement with no signal. Phones with B12 normally would have 1 or 2 bars in my office.
I installed SQL Editor and went to the location of settings.db but nothing is in the Database folder

You can create it within the settings than enable/toggle it.
Since you have it already in the settings I don't know if it will make much difference. Won't hurt to try.

no luck sorry

Also on T-Mobile & same results, nada with SQLite, VoLTE was enabled by default, noticeable in the notification bar upon booting the latest EU ROM Update.

[Q] T-Mobile Version Network?

http://imgur.com/a/E7wY0 < Pics lol. So My Phone wasn't showing LTE at the top and it's had a "!" with 5/4 bars showing so I panicked thinking I didn't have LTE (Which I did, I don't know why the Symbol went AWOL) so I went into Networks setting and changed Preferred Network Type into LTE (recommended) about 30mins later I got the LTE Symbol back. So Is there anyway I can change it back to "Global" and not LTE (recommended)? I just wanna make sure I can get 3G/2G when needed even tho I normally get 4G LTE everywhere I live hehe. I have bad OCD lol and this is affecting me badly LMAO
Is global really needed if you're in the states? I have mine set to LTE as well but I get 3g.

dial *#*#4636#*#*, then choose phone info, scroll down then change lte only to either lte/gsm or lte/gsm/cdma.

instead of dialing, there an app that will take you to that location if need be, its called the 4636v2 app https://play.google.com/store/apps/details?id=com.kei5rio.secretcode&hl=en

H --> R --> H?

Hello, new to the Nexus 6. I'm having a little issue. I keep getting an exclamation and an R, then back to H on my Nexus 6. I noticed that I wouldn't get connectivity if I didn't have Roaming enabled. I got it from Amazon Prime, which says it's a local edition of the Nexus 6 (not imported). And right now, for example, I'm on wifi. I see the Wifi symbol and then an R appears. It says I'm on roaming and then no? Hmm...
I've recorded this video of it, would you mind checking it out and letting me know?

Thanks.
Suggests that your service provider may have a weak signal in your area, or possibly they are experiencing technical difficulties (tower going on and off... I've seen this kind of thing happen lots of times). The fact that it switches to 3G/H *ever* means that it actually is compatible with your carrier.

I know it's not the issue. I have a note 4, same service provider. Also my partner has a z ultra and same service provider. No issues either.
I went into the sim toolkit and changed the roaming settings. Now let's see if it fixes the issue because it's driving me nuts. Lol.

I'm using a rom that is close to stock, I've had similar issue before. Try playing with the mobile data settings to see if this solves it. My carrier is Verizon.

Cannot Connect to LTE. Throttling?

Hi,
Since last Friday I haven't been connecting to LTE. I'm running multirom with the latest BBOYZ Sense ROM and then on secondary a minimal GPE ROM without root that I just use when I want Android Pay. Neither has connected to LTE since Friday. I'll see LTE show up for a second but it won't spin like it's doing anything and eventually will switch back to 3G. I have unlimited data and have never had a problem in the past. This monthly cycle I've used 0.6553GB of 3G data, 1.5186MB Data Roaming, and 13.4001GB LTE. My wife's iPhone 5s still connects to LTE just fine. We have a tower near our home and get a great signal. My wife has used about .25GB. Billing cycle says tomorrow so that might mean it resets tomorrow or tomorrow is the last day, not sure. Anyone have any thoughts? Am I being throttled? Or maybe I just need to give it a full wipe and flash a RUU?
Thanks!
I decided to try a full RUU. Still only getting 3G. I did some reading and saw Sprint (about 2 weeks ago) said they're going to limit high volume users when they get over 23GB but that they'd be notified. I haven't been notified or used that much data. I guess I'll see what tomorrow brings. If I get into Wednesday with no LTE I'll head over to my Sprint store..

Have you tried either ##72786# or ##3282# while using a Sense ROM?

I went into both those menus but wasn't sure what to do. Was about to ask but I disconnected from wifi and now have LTE. Don't see how that helped but maybe it did! Thanks regardless!

Won't switch back to 4g lte vzw

Hi, so I am running nx rom 9.8.1 on my xt1060 de. I am having a problem where the phone goes to 3g and won't come back to 4g without toggling airplane mode or restarting.
I have pushed fsb.bin and non-hlos from the Verizon stock file. I have deleted modem st1 and 2, and have replaced the apn with one I found for Verizon specific.
Still, I get stuck on 3g.
Any ideas

Does the same thing happen on stock?
No, on stock it holds 4g well. I had a host of other problems on stock, but it held signal

In the early lollipop builds for my porevious device (RAZR M), I use to modify/add the build props as below to improve my switching over to 4G. I don't think it will work you, but hey, give it a try, after a backup...
Code:
telephony.lteOnGsmDevice=1
ro.telephony.default_network=9
ro.ril.def.preferred.network=9
Basically, its setting the default network to LTE, the preferred network to LTE and setting the GSM device to allow LTE. You may be lucky and it might work.
UPDATE: I'm not sure if I should be happy or sad. I reset the entire phone, clean wipe and put the factory image back on vs NXROM. Same issue. Did some digging and found some suggesting that a SIM swap helps. Had a spare and popped it in. Things are back to LTE for the time being.

thanks for reporting back. glad to know it's not the ROM.

Change Carrier Name?

I recently switched carriers from MetroPCS and I'm now currently on AT&T through Straight Talk. The first thing I noticed after I switched sim cards and my service was finally activated, was that the carrier name shows "Home" instead of "AT&T" of "Straight Talk".
Is it possible for us to change the carrier name?
I'll attach a picture to show what I'm talking about

Given that I only see the carrier name on my lockscreen for a few seconds until I've unlocked the phone, I see little point in changing it. Now, it can be done, but I believe you need Xposed and GravityBox to do it.
It's one of those things that just kind of nag me when I pull down the status bar
I would use xposed, but I'm pretty sure that it's still not compatible with Android N yet. I was looking for alternative ways of doing it.

I don't believe there is an "easy" way to do it. You're probably going to have to decompile framework-res.apk and edit the carrier name in strings.xml, then recompile the framework. That is probably as simple as it gets, as I don't think there is an app that will do it for you. But search the site. You may find something that works that I haven't found.

You can use a custom rom to hide it. To be able to change it takes a bit more.
I find it annoying as well that is why I only run roms that allow me to get rid of it. I know what carrier I use. I dont need to be reminded.
