[Sony Xperia XZ2 Questions & Answers] Ascertion:
I posted this on Reddit.

https://www.reddit.com/r/tmobile/comments/98qqs0/_/

Note: this is in relation to the Zenfone 5z, but it relates as it also doesn't support VoLTE in the US on any carrier.

From the comments, it appears (at least in my case) that T-Mobile automatically allows OEMs to utilize their VoLTE services, but the OEM must load the T-Mobile default profile in IMS registration for it to work.

VoLTE works fine on my OP6 but it does not work at all on the Sony XZ2, it says it is not provisioned just as you can see in *#*#4636#*#*.

Sony is too lazy to load the T-Mobile or Cricket profile. Leaving it without VoLTE support in the USA.

Speeds do not matter with VoLTE, 8mbps (which is what Cricket throttles to) is plenty fast enough for VoLTE to work. At&t doesn't allow unlocked android phones to use VoLTE, but I'm not sure about Cricket.
[Sony Xperia XZ2 Questions & Answers] MartinX3:
I have VoLTE and WiFi-Calling.

But at the German Provider O2.

And in every country via roaming.
[Sony Xperia XZ2 Questions & Answers] kwanjai:
If it helps anyone, I'm pretty sure it's firmware related.

I'm on the Canadian carrier Bell that supports VoLTE. With my carrier firmware VoLTE is displayed and automatically enabled on the top status bar.

Now, since I have been flashing my firmware to other operators and model numbers, recently (in hopes to try out the Android Pie beta on my unsupported H8276 model), I've noticed that when I flash to other firmwares I lose VoLTE.

Hope this may help some of you

Edit I'm guessing based on my observations [MENTION=4852983]Asers[/MENTION]ions more technical response is true about having to add your carrier's IMS record profile for it to work.

Hello everyone,

as most of people here, i have a XZ2 H8266 bought in august of this year stock, in France.

i was so excited to replace my old Sony Xperia X to get volte on , but after look and try a lot of thing, no Volte is enable.

my operator is Bouygues and option volte and vowifi is enable.

i try my card sim to another smartphone and volte is working nice , so the problem is the XZ2

i read all 12 pages of this thread and try all people tips given, but not working . As MartinX3 say, i try to flash with flashtool a Germany firm, but not working.

i use my XZ2 as a modem and the 3G / UMTS /HSPA is not great receive but nice in 4G/LTE

i'm almost shure my operator is certified the single sim because they sell it, volte should be okay (i need to confirm that on their shop reseller with demonstration model)

Recently , I made update to Android PIE and still volte not working.

any issue please ? thanks for your help :)
[Sony Xperia XZ2 Questions & Answers] wbcd:
thanks for your screen share MartinX3 : )

in my remember, you have not the H8266 but only a Firm, you have a international H8296 ?

it's to weird for a brand new phone release...

EDIT : i just saw , you update M to P and it still working for you , i'm so envious
[Sony Xperia XZ2 Questions & Answers] MrUtube:
VoLTE is carrier controlled. They control it so they can try to force you to purchase phones they sell directly. Kind of how Nexus 6P VoLTE & WiFi calling works on all carriers out the box, but for it to work on VZW you have to have the My Verizon app installed on the phone, otherwise the feature is blocked
[Sony Xperia XZ2 Questions & Answers] neofire4:
So, does the H8266 variant support t mobile's volte or wifi calling as of now (or will it ever?)? I'm thinking of buying this phone, but carrier support doesn't seem too decent from what I've been reading...
[Sony Xperia XZ2 Questions & Answers] Haldi4803:
While WiFi calling has been broken for me for quite some time now, I did get the VOLTE symbol just yesterday.

Pretty sure my provider just activated it recently.
[Sony Xperia XZ2 Questions & Answers] MartinX3:
Which German provider do you use?
[Sony Xperia XZ2 Questions & Answers] Haldi4803:
Swiss ;)

It's Yallo, uses the Sunrise network.

Oh and BTW, even got WiFi calling working flawless now....
[Sony Xperia XZ2 Questions & Answers] SwanySwabbyShwammy:
Any chance I could get said firmware to flash (I have an ZX1 Dua, really want dual sim with VOLTE and VoWiFi to work on Tmobile. Did you get this to work on the Pie update?
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] amdsap:
What stable WM6 ROM can I use to enable video calling on AT&T 8525?

Can I use the Official WM6 HTC TyTN ROM?

I already used the HTC Hermes SIM & CID Unlock.

I am using WM6 3.62.502.3 AT&T ROM

Tnx:)
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] XtreMe_G:
you dont need a whole rom, you just need a 3g dialer

that being said, at&t does not support video calling, there's this new video share thing, but i dont think its the same thing
[8525, TyTN, MDA Vario II, JasJam Software Upgradin] cnpthe3rd:
No Video call on 8525

:rolleyes:

There are lots of roms with video calling that will run on an 8525 but there are two SMALL problems 1 AT&T doesn't support video calling and 2 (the SMALLEST problem) the 8525 doesn't have a front facing vga camera for video calling you will need in addition to a good rom a vga camera (the smaller the better) next a drill and torch cut a hole in the front of your 8525 and install the camera next solder the leads to the main board of your phone oh yea GOOD LUCK

I recently bought an APTX compatible earphones and I don't know whether it's enabled or not as there's no notification saying 「You're using APTX codec」

I wanna ask is there any notification pops up when a APTX device is being connected?(I'm sure a notification will pop up when connecting APTX-HD device though)
[LG V20 Questions & Answers] androiddiego:
APTX = no notification. APTX HD = notification
[LG V20 Questions & Answers] PhantomGamers:
Can you take a screenshot of the notification? My bluetooth adapter for my car is advertised as APTX HD and I don't get a notification when I'm using it hm
[LG V20 Questions & Answers] androiddiego:
I don't have a APTX HD device. The LG website says that the V20 is APTX HD compatible. Others have said that APTX alone doesn't give an icon, but APTX HD does.
[LG V20 Questions & Answers] zack1175:
If APTX HD device is connected, message will pop up saying APTX-HD device is being connected. However, it's a bit strange to hear that connecting APTX device will not get any message though.
[LG V20 Questions & Answers] PhantomGamers:
I wonder if maybe this notification is only on the KR version o_O
[LG V20 Questions & Answers] HD2FORNICK:
I have a non APTX Phone and a V20 and when I connect my APTX headphones to both I can tell a difference in sound quality right away. The V20 does not have any indication for APTX and that is a bit strange.

[LG G5 Questions & Answers] Davy49:
Hi All,

I recently purchased this phone on eBay: LG G5 H830 32GB T-Mobile Unlocked GSM LTE Smartphone Silver, in the product description under 'Lock Status' it states this

Lock Status:	Network Unlocked..I purchase a Cricket Wireless SIM Card kit and have activated my phone with them. My question is concerning this procedure:

How-to Boot into Recovery/Factory Reset

1. Power off the phone. Unplugging the USB cable can also help.

2. Using 2 hands.. use one hand/finger to press/hold volume down.. and use the other hand for the power button. Press n hold both buttons.

3. As soon as you see the LG logo on the screen.. let go of the power button then quickly press it again (never letting go of volume down).

4. Keep holding until you see the Factory Reset screen.

If I perform this, will I lose the 'unlocked' status of my phone, what I'd like to do is remove all T-Mobile branding of my phone ( Boot Screen,Shutdown Screen, T-Mobile Application's..Etc.) I feel sure I'll need to root my phone to get all of this done, I already have the developer options enabled, and have the 'Allow OEM Unlock' function turned on, as well as USB debugging enabled. Ever since my phone got upgraded to android 7.0, I've been having issues with the mobile network function ( as far as showing I'm using the AT&T network (via Cricket Wireless) when I turn off wifi connectivity. I'm hoping someone else in here has had a similar experience, also..I've never rooted a phone previously.

Thanks,

David :rolleyes:

Once your phone was permanently unlocked it will not lock your device even if you perform hard reset.

[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] Aalesund:
There is not anymore Recovery partition name in Oreo. Now the partition is called "recovery_ramdisk".

Also why ADB? You must be in the FASTBOOT mode (Bootloader).

Tested and works for me.

Try to reflash TWRP with TWRP 3.2.1-0 April 8th build Round 2.

fastboot flash recovery_ramdisk TWRP.img

But why the screenshot doesn't works? I can't make screenshots in TWRP.... :(

I use 2 sim cards, so NO SDCard in my phone. Maybe this is the problem?

I successfully flashed on my P10 (VTR-L29C636B361). Unlike other TWRP version I tried, this one had adb working. However, I got "E: failed to mount /cache (Invalid argument)" errors for any partition I tried to mount. All wiping and reformatting tips I found did not work. Any tips?

After that, I flashed this TWRP version: https://xdaforums.com/p10-plus/development/recovery-twrp-3-2-1-0-oreo-t3734993. With that, I could wipe and mount the partitions normally. Maybe I'll try the version of the OP again.

Still boots to eRecovery not TWRP

I tried flashing this but I still get eRecovery when I try to boot into recovery mode. Have I missed something?
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] :
When you hold volume up in the "Your bootloader is unlocked" screen then it boots into eRecovery.

In order to boot into twrp you need to completely turn off you phone then hold volume up and power until you see a screen that says "You device is booting now..."

Also this TWRP is kinda outdated use this one instead. The other one supports both MTP and Device decryption:fingers-crossed:.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] TheLazyHatGuy:
That's strange because II'm nearly certain that when I had EMUI 5.1 I could just boot into TWRP when I help the Volume up button. I tried flashing the version of TWRP you suggested and I still can't get into TWRP and only see eRecovery.

This is even shown in the guide you linked

"As soon as you execute the restart command,remove the USB cable and keep pressing Volume UP,so the device will boot to TWRP.This is to avoid that the device boot to OS,overwritting TWRP recovery."
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] :
Sorry. I should've said that that is just one way to boot into TWRP. Of course there are other ways to boot into TWRP, you can just restart your phone but then you need to be holding volume up before the phone boots. When you hold Vol Up in the screen that says "Hold volume up for 3 seconds to boot into recovery" then that boots you into eRecovery not TWRP.

That was the mistake I did when I began modding my phone;).

Also make sure that when you flash your recovery on Oreo type "fastboot flash recovery_ramdisk" not "fastboot flash recovery".
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] TheLazyHatGuy:
Yeah. I figured out that because I didn't boot directly into TWRP after installing, it was being overwritten by eRecovery. Finally got it working so now I can install Magisk and Xposed again :fingers-crossed::fingers-crossed:
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] :
Also when you install Xposed on Emui 8 you need to install v90 beta 4 otherwise you will get bootloop:fingers-crossed::fingers-crossed:.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] TheLazyHatGuy:
Thanks that worked perfectly :):)

p10 lite with pie rom and stock recovery.

can i install twrp.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] nopezip8:
Hi world(first post since android),

I have P10 lite for almost a year(not rooted for warranty issues).

I wanted to perform a stock firmware backup before I endulge in rooting/custom ROM.

Is that possible with TWRP(with or without rooting), and are there any how-to's?

Sorry for being such a newbie, just like to upgrade to 8.0 and revert back ro stock in case of a problem or warranty issues.

Thank you.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
It is possible without root but you have to unlock bootloader and flash twrp. And that is now impossible to do if you have latest update.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] nopezip8:
I think it might be the answer to my question, but my case that I dont really understand what is twrp. Does it replace thee boot loader? In that case will I lose the stock bootloader and is it reversable(lol is it backupable too)? And also, is this tool in the first page able to unlock the bootloader(have you tried it). I would want to backup the whole stock firmware image for later recovery/restore(warranty issues)

Thanks again.

---------- Post added at 12:02 PM ---------- Previous post was at 11:57 AM ----------

I dont have the latest (security) update ( the one that downloaded OTA *184 . I chose not to install it just because you never know what it limits. ( I read it possible at first :) )
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
TWRP is custom recovery. Unlocking bootloader allows you to flash recovery partition. You flash twrp because it's the best custom recovery (at least for me). Then through custom recovery you flash custom firmware.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] nopezip8:
Can you confirm I can backup my old stock firmware (ROM) and boot loader? (Very important)

I wouldn't want to flash a custom firmware without those steps(again, for warranty issues, or just to be safe if the custum firmware has bugs or compatibility issued)

Also you didn't mention, or tell how to unlock the bootloader, maybe a link to thread, or should I search the forums on that keyword (would appreciate it) also important..

---------- Post added at 02:05 PM ---------- Previous post was at 02:02 PM ----------

I found this thread about unlocking bootloader, but it says discontinued.... Maybe not for my not updated p10 lite ?

https://xdaforums.com/p10-lite/development/dev-lxx-toolkit-one-t3771015
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
So unlocking bootloader is no longer free, but you can unlock through DC-unlocker for 4€.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] nopezip8:
Will I be to be able to return it to stock after(bootloader and firmware/os). If so, does that tool provide the firmware backup (not just setting scand stuff)

If so, please provide the link.

Thanks
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
I tried unlocking and relocking my p10 lite and it worked ok, but if something wrong will go with motherboard or something like bricked phone. Warranty (probably) won't work, but if you have broken like screen Warranty will still work. But I guess you can relock your phone and still be undetectable.

---------- Post added at 03:26 PM ---------- Previous post was at 03:22 PM ----------

And yes. You can backup firmware through twrp. And if you brick your phone you can use HURupdater through twrp to unbrick it. I bricked my Huawei p10 lite a lot of times. And also it has modded android and works like a charm
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] nopezip8:
Well, I got the official Twrp app, but it requires root permissions to backup recovery.img ( im not sure if that is the whole Firmware though). Even if it is, you would end up with a backup-ed version with root permissions, I am actually asking if there is an other option of firmware backup through adb from pc (or this HURupdater you mentioned) that backup's the current not-rooted version ( so I don't do undo root , since I don't believe it's entirely undetectable) not risking warranty issues, since I think it's stated that rooting compromises the warranty. And it's more like, you better have the original firmware backed up.

I'll need to back it up manually, since I couldn't find it on their site and then do some mods and/or root it (I got a year left warranty, I think it will last that long)

I think I will search that HURupdater tool in the forums anyways.

Thanks for feedback, add freely any suggestions.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
You can always download original firmware through huawei firmware finder. HURupdater only is flashable through twrp. And download twrp from xda forumas not the app. Because I don't think there's twrp in the app.
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] nopezip8:
I think it's not that safe getting the firmware from other app, unless you got Android studio to compare it against the official google android(malware etc). Also you you have to somehow decrypt/decompile and recompile it. That's why i'm reserved into updating without having the original backed up.

I Don't know why Huawei doesn't offer it's firmware on their site, maybe they got some only for authorised FTP server only few know. Which isn't the case for other manufacturers (htc/iphone etc).

Or maybe I just didn't search enough .

So, the question remains the same, is there a way to back up stock firmware without rooting or desoldering the eMMC chip, or can I find a firmware on Huawei site( not to worry About those 3rd party malware).

Thanks
[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
Huawei Firmware Finder downloads firmware from official huawei site. I used it quite a lot of time, and it works fine. I think it downloads from hisuite server,i don't really remember

[Huawei P10 Lite ROMs, Kernels, Recoveries, & Other] justinas2003:
