I have a Sprint M8 that I unlocked - it no longer complains that an ATT sim card is the wrong network. However, it doesn't seem to match the LTE bands for ATT so I can't get LTE. Well, sprint uses band 25 and ATT band 2.
But isn't the hardware capable of both and the software used to select? Are the phones actual physically different? I've fiddled with *#*#4636#*#* menu and not gotten anywhere.
Can I flash an ATT radio; would that change the available bands? Or have I reached the end of the road playing with this particular device?
---------------------------
Yet another question. As far as I can tell, you can't roll back to a previous version with an MUU. I'm at 4.25.651.14. I want to try ATT RUU (4.28.502.1) and / or developer RUU (4.16.1540.8) but is it possible to RUU a lower number, such as going to the developer or back to Sprint after the ATT one? When I just try to run the RUU it won't install the lower one; can someone link me to the obvious post I missed on how to downgrade?
----------------------------
And can I install Cyanogen 4.4.4 on top of the firmware that came in thr 5.0.1 RUU? Let me rephrase that - should I be able to? I've tried and bootlooped. If it shouldn't work I'll give up. If it should, I'll keep beating on the poor thing.
Thanks in advance for the help.
I'm very concerned about this.
I just signed up to Tmobile all unlimited plan and I got a Nexus 6 directly from Motorola, not from T-mobile store, so I just inserted the Tmobile nano sim, my phone is totally unlocked.
Before I proceed to any flashing and do it by my own wihthout knowing if it will work, I want to know who has experience or has changed from LMY47Z to LYZ28E build
My phone is a
Nexus 6
Shamu XT1103 32GB P3A0
Lollipop 5.1.1
Stock
Rooted,
Baseband version: MDM9625_104446.01.02.101R
Kernel version 3.10.40-geec2459
Build number: LMY47Z
Custom TWRP
It seems that doesn't have the wifi calling stuff on any of my options, I could not find any about wifi calling options, I read somewhere that I need to install the LYZ28E build to make it work with WIFI Calling.
Can I flash LYZ28E stock version on my current Nexus 6 build: LMY47Z even when I did not buy the nexus 6 from Tmobile?
Shall it work fine with all other carriers as AT&T, Movistar, etc with LYZ28E?
I have read that LMY47Z is sprint build version, but it works great on AT&T, Telcel and Movistar (Mexico), I have not tried on CDMA carriers yet.
I read that whether you change the OS build version comes with different radios, etc and I don't know whether shall affect other carriers as AT&T, Movistar or Telcel if you later on I want to swap nano sims, because that's what I do, I always swap swims when I'm in USA or Mexico.
Using Wugs Fresh tool to proceed to these changes first I need to go back completely to stock rom + unroot and then flash new build that should be LYZ28E, Am I right?
Please advise about steps that I need to do and if it is possible to do on my Nexus 6 build number that I currently have
I appreciate it on advance!!!

Yes, if you want T-Mobile WiFi calling, flash LYZ28E or a custom ROM that supports those features. Yes, you can use any build on any carrier. I'm on Sprint and I have successfully used every build.

Awesome man!!!! thanks for fast response, take care, I will do it!
it works
Switched a nexus 6, purchased from verizon, running 6.0 (MRA58K), rooted, from verizon to t-mobile today 12-10-15 and the wi-fi calling feature in settings->more appeared. Went into airplane mode turned on Wi-Fi calling and successfully made a call and it sounded good.
The unlocked version doesn't support wifi calling and band 12. Are there any guides on how to flash the T-Mobile stock rom?
Hi i was wondering what region/stock Android 10 rom version would be best to flash prior to the lineage or similar ones for use on at&t? The LG v40 i have is v405ua but it doesn't look like there's a official 10 stock rom for it.. i had cross flashed an at&t pie stock rom as it kept dropping calls I assume it was modem firmware. And yes bootloader is unlocked.
Well, a few things... 1st, if you want to use at&t as your carrier, then u have to have an at&t device / rom to be able to use vowifi (and I think volte). So, if you need those, then you have only one option, flash an at&t rom to your at&t device (they can verify if it's at&t by the imei number, so no, you can't take a sprint one and flash at&t rom).
2nd, lineage doesn't support vowifi nor volte. So for us in the states, this is a problem as the 3G netwroks disappear, you'll be unable to make a call without volte.
3rd, any stock 10 would work with (latest) lineage. Lineage doesn't need a 'specific' one to work, it just needs that OS level. There are older lineage builds that work with 9. Maybe check one of those to see if it meets your needs before doing more?
cheers
Hi all, I just got a SM-G973U1 (unlocked snapdragon) to replace my old S7 international version that doesn't have working VoLTE. AT&T is shutting down 3G in February, so I need to set up this new phone so that it works in LTE only mode.
I'd like to use TWRP recovery and Magisk root, but I doubt any ported ROMs will work because of Samsung's proprietary drivers for VoLTE/HD voice. What's the best stock-based ROM available for this device? Alternatively, where can I find detailed instructions for installing these items myself and removing Knox and other safeguards from the existing stock firmware (possibly using adb shell)?
If necessary, I'm willing to use the ATT CSC code on this phone. This is not the current CSC on this device.
I'm returning the phone because I haven't found a way to unlock the bootloader.
