Alright so the verdict is that there is some significant battery drain.

Normally at this point in the day I'd be around 65-70%. Right now I'm at 53%.

I like the better screen rotation, the granular volume adjusting, but not for the drop in battery life.

I'd suggest waiting.

I went back to 47.1.A.12.119 when the best I could do was flat idle.

But it does prove that the XZ1 will still do fingerprints + VoLTE + VoWiFi in Pie.
[Sony Xperia XZ1  Questions & Answers] bigrjsuto:
Exactly. To me, that's the biggest takeaway from my trial. For me, this means I'll be holding on to the XZ1 for as long as they keep spitting out updates.
[Sony Xperia XZ1  Questions & Answers] dcrin3:
After booting up the lockscreen loops over and over trying to unlock. It's definitely more buggy this time around for the XZ1/XZ1c VoLTE combo.

It works though, here are the shots.

Ok so, I mixed:

1. XZ1 47.2.A.6.30 US

2. XZ1 47.2.A.6.30 RU - system and vendor

3. XZ1C 47.2.A.4.45 US - oem

So far, fingerprint, VoLTE and Wi-Fi calling work. No unusual battery drainage noticed. Everything works nicely and smoothly.
[Sony Xperia XZ1  Questions & Answers] ray2050:
I noticed that a few days ago the XZ1 US 47.2.A.4.45 was re-posted with R3C revision. Did anyone successfully download it? I tried downloading it twice, XperiFirm reported unpacked successful, but I only get partial files in the folder, is there something I missed?

Also, if anyone tested this one, does the battery drain issue get fixed? I'd like to know. Thanks!
[Sony Xperia XZ1  Questions & Answers] Uxorious:
Same problem here ... I mentioned it on the XperiFirm thread.
[Sony Xperia XZ1  Questions & Answers] ray2050:
Looks like it's been fixed and I just downloaded it successfully. It doesn't show on the firmware list on XperiFirm, but you can re-download it if you tried it before and still has the record in the downloads list. Some file are dated today so it's newly updated.
[Sony Xperia XZ1  Questions & Answers] Uxorious:
How do you download it?

XperiFirm just shows the 47.2.A.6.30-R3C release now...
[Sony Xperia XZ1  Questions & Answers] ray2050:
Click on the up-and-down arrow button at the lower-right corner from XperiFirm, it'll show your download history, If you didn't clear it. Just find the record and click on start, it will download a new copy, that's how I did it. Hope it works for you.
[Sony Xperia XZ1  Questions & Answers] Uxorious:
Nah I cleared it already.

Any chance you can ZIP it up and upload it to me?

(I can share a Google Drive folder for you to upload it to...)
[Sony Xperia XZ1  Questions & Answers] ray2050:
There might be an easier way. You can import my download history xml file, so you can download it directly via XperiFirm. I'll PM you.

If that doesn't work I'll upload it to you.
[Sony Xperia XZ1  Questions & Answers] Uxorious:
That worked - thanks.

Download just finished, and I compared the R2C with the R3C release:

elabel-G8342-row-row_201809030842515.1_47.1.A.12.270_X-FLASH-LTALABEL-C93B.sin is missing in the new release - doubt that matters.

fwinfo.xml shows the new revision number.

oem_X-FLASH-CUST-C93B.sin is different - but that doesn't matter in this thread since we're replacing it with the XZ1c version.

userdata_X-FLASH-CUST-C93B.sin is different - but I always remove that so I don't wipe my device.

In other words, for mixed-flash users in this thread I wouldn't worry about this release.

Hopefully they will release the XZ1c 47.2.A.6.30 version soon.
[Sony Xperia XZ1  Questions & Answers] D-Rock93:
So if I flash the new customized us firmware on my xz1 that just got released a few days ago but I still have the old xz1c firmware oem file for wifi calling and volte, do you think it would mess anything up or will it work just like normal? Or should I just wait for the xz1c updates to catch up?
[Sony Xperia XZ1  Questions & Answers] Uxorious:
From people who have tried that in the past, it won't work properly.

But I don't think there's any risk in trying ... you can always get into the flash mode and reflash the device with the old one.

NOTE:

The only weird thing I've seen was one update a while back where I couldn't go back to the previous one without wiping all settings/data on my phone.

I think that was on a major version upgrade though, so I guess it would make sense if some Android DB got updated.
[Sony Xperia XZ1  Questions & Answers] sethstorm:
The drain is still there, even after a factory reset.
[Sony Xperia XZ1  Questions & Answers] ray2050:
XZ1c 47.2.A.8.24-R7C was finally released yesterday, XZ1 47.2.A.8.24-R3C is still available, anyone interested should download these asap before the versions go mis-match when the next updates arrive.

Good to know, thanks for the feedback. Hope we will see some improvements in 47.2.A.8.24. Time to start a new test....

47.2.fsc file?

I was hoping to try 47.2.A.8.24 this weekend, but what does one use for the 47.2.fsc file? Thanks Paul
[Sony Xperia XZ1  Questions & Answers] Uxorious:
I mixed US + CE1 + USc as usual and it works fine.
[Sony Xperia XZ1  Questions & Answers] pereimer:
Could you help me by being a bit more specific, what did you take from each one? I'm working on a G8441 or ZX1compact. Also, what did you use for the 47.2.fsc file?

Thanks,

Paul
[Sony Xperia XZ1  Questions & Answers] Uxorious:
No idea what that file is.

You download the releases you want with XperiFirm.

It will extract each of the updates to a separate folder.

You then start with the US base release directlry.

Copy system_X-FLASH-ALL-C93B.sin and vendor_X-FLASH-ALL-C93B.sin from a region other than US to retain fingerprint sensor.

Copy oem_X-FLASH-CUST-C93B.sin from the US XZ1c to enable VoLTE option in settings.

REMEMEBER TO DELETE userdata_X-FLASH-CUST-C93B.sin IF YOU DON'T WANT TO WIPE THE PHONE.

To flash it:

Power off your phone.

Connect USB cable while holding volume down - phone will show a green light in the corner.

Run newflasher from the directory you combined the firmwares in.

(If you haven't installed the drivers, newflasher asks you if you want to extract them)

After it's done flashing, unplug the USB cable.

Sometimes the phone keeps the green light on ... if it does then hold volume up and power (I think that's what it is) to force it off.
[Sony Xperia XZ1  Questions & Answers] pereimer:
Thanks for your input. I used

G8441_Customized US_1310-4371_47.2.A.8.24_R7C​

with

system_X-FLASH-ALL-C93B.sin, and

vendor_X-FLASH-ALL-C93B.sin

taken from

G8441_Customized DE_1310-4373_47.2.A.8.24_R3C​

and it worked perfectly.

The 47.2.fsc file which I mentioned earlier is in .flashtool/mydevices/G84XX/ . I just renamed the 47.1.fsc to 47.2.fsc.

---------- Post added at 10:42 PM ---------- Previous post was at 10:25 PM ----------

A week ago, my XZ1 compact G8441 asked if it could upgrade. I naively said "yes". I had been running a hybrid of the UK 47.1.A and the US 47.1.A, so I probably should have ignored it and refreshed myself. After the upgrade, it could no longer connect to the network or WiFi. After trying many things, I gave up and purchased a new phone. Today I was trying to debug the old phone again and noticed that the IMEI was blank! I assume that this happened during the upgrade to 47.2.A.

I really would like to be able to used my old phone--I really liked it. I know the correct IMEI number with which to program it. Is there any way to put the IMEI back in place? I know that this is not supposed to be possible, as it is supposed to be a security feature to allow stolen phones to be blacklisted, but I really would like to have that phone back.
[Sony Xperia XZ1  Questions & Answers] SGH-i200:
This works because the CE1 system.sin contains the 'Modem Configuration' files needed for the US carriers. Too bad the German carriers are not included in the G8342 firmwares.

I just installed CE1 47.2.A.10.80 with US customized 47.2.A.10.80 oem.sin file and I got mms working and fingerprint but wifi calling broke, maybe it's the kernel I'm using that broke it but I'm not so sure yet, I have to wait till Sony stops dragging their feet and releases source for the kernel when they release their next stock update I guess...
[Sony Xperia XZ1  Questions & Answers] shilent:
I flashed my G8341 to a stock US firmware hoping to have VoLTE. Unfortunately I don't see the option, and it drops to 3G when making calls.

After some searching, I've read that the phone will enable VoLTE only if it sees a T-Mobile SIM. I'm using Mint Mobile (which is on the T-Mobile network), could this be why?
[Sony Xperia XZ1  Questions & Answers] krchi:
Granted I lost my phone a year ago, if you are on purely stock US firmware VoLTE and WiFi Calling WILL NOT work. You need to do firmware mixing as most people has done on here. I had mint sim in the XZ1 a year ago and it worked fine with VoLTE and wifi calling.
[Sony Xperia XZ1  Questions & Answers] shilent:
Thanks, I thought people were mixing only to retain finger print scanner. I've flashed using mixing based on the previous posts , and now finger print scanner has returned and I have VoLTE option and Wifi calling option. It still drops to 3G or H+ when making calls though.

I'll do more reading and update this thread if I ever get it to work.

Hey guys, looking for some input. Got an Int XZ P dual sim. Running stock ce1 firmwear. I would like to keep the fingerprint enabled and get volte on tmobile usa working. Ive read many threads and have a ton of mixed info. From what I got was to flash the latest US firmwear and than some .sin files from the CE1 firmwear to get the fingerprint working. This is where im confused, what files do I need to flash?

Thx.
[Sony Xperia XZ1  Questions & Answers] krchi:
Recently got a G8343 after losing my G8341. I tried to enabled VoLTE and Wifi Calling and once again to no luck. I've identified the problem to be "amss_fsg_X-FLASH-ALL-C93B.sin" this sin file which when flasheding from the G8342 model onto the G8343 it causes the sim to not work. The phone no longer reads an IMEI number for the sim slot, whereas IIRC the G8341 even though showed 2 sim slots, 1 sim slot still had IMEI number. I was not aware of any hardware differences between the 2 model... as the G8341 firmware works flawlessly. I've done some light digging and https://mt-tech.fi/en/modify-sony-xz-xzs-xz-premium-xz1-and-xz2-lte-a-band-combos/ and https://xdaforums.com/showthread.php?t=2418893 might shed some light as to why this is isn't working. I currently am busy with school so do not have the time to investigate and as the XZ1 is not my daily driver I am not in an urgent to explore this, but if someone is feeling adventurous please do some investigation and report back!

EDIT: I think it's the issue of bands, if you look in this GSMARENA photo, the G8341 (international single sim) and G8342 (dual sim) share the same LTE bands, while the G8343 (canada single sim) is lacking a few of the said bands. The missing bands might be cause of why it has not been working.
[Sony Xperia XZ1  Questions & Answers] DBGrip:
Did you ever figure this out? I had recently flashed my wife's g8342 with US + CE + XZ1c us, and everything is working. So I decided to order a g8342 for myself $175 new.... they sent me a g8343...... I reached out to swap it, but have been trying to get it to work anyways. Tried using 8342 firmware but that lost recognition of SIM and IMEI. Have reflashed to a combo of 8343 (Freedom) with OEM from XZ1c. Wifi and Volte are there as options but do not work. No wifi calling icon, no HD calls. Thinking of trying 8343 freedom with 8341 ce system and xz1c us. Had read previously that some one had found that ce in 8342 unlocked the modem bands or something like that?
[Sony Xperia XZ1  Questions & Answers] SGH-i200:
System should be 8343 or 8341, since both are single SIM!
[Sony Xperia XZ1  Questions & Answers] DBGrip:
Yeah. From what I've gathered the 8343 system doesn't open the right T-Mobile settings that the xz1c compact own unlocks. Seems the only USA system in Xperifirm is the 8342, which doesn't recognize model 8343 SIM slot, but works on the 8341 model even though it's single SIM.

Sent it back. Looking for 8342 or 41 now. My wife's 8342 is still working perfectly with custom flash ROM [emoji849]
[Sony Xperia XZ1  Questions & Answers] Sliftw:
Did you ever get your G8343 to work with Tmobile VoLTE? I have an unlocked SOV36 G8341 and when i flash G8342 firmware on it, there is "no sim found" message also. Swapping the XZ1c oem file with the G8341/G8343 firmware isnt enough because the "amss_fsg_poplar_dsds_tmobile_us_ims_tar.mbn" doesnt get loaded still.

Does anyone know how to make a zip file patch for TWRP with the G8342 firmware modem files from system.sin?
[Sony Xperia XZ1  Questions & Answers] fake0123:
Hi all,

I have a G8342 (XZ1 Dual) that I flashed CE1 firmware when I first got it from US firmware.

Now with Volte and all, I have to go back to US firmware, so I want to do a mix firmware flash.

US firmware for Dual

CE1 for fingerprint

US from XZ1 Compact for VOLTE

Before flashing I can delete userdata file to keep my data.

My question is if I delete userdata file, will I really keep everything, like text messages, phone call history, apps installed, app data, etc. Meaning it wil be like a normal udpate?

Or will I have to reinstall everything, but app data will be kept?

Will I have to sign in back to google?

For those who flashed, right ater booting up the phone, how did it look?

Thank you.
[Sony Xperia XZ1  Questions & Answers] pbarrette:
If you delete the userdata SIN file, you will keep all your apps and settings.

The userdata sin file basically reformats the "/data/" partition, which is where all your personal data is stored. This personal data includes the stuff you can see, but also the stuff you normally can't see without root. Stuff like your Google login info, app installlations, etc.

So as long as you are flashing the same FW version or newer, deleting the userdata SIN file makes it just like an udpate.

I'd consider looking at the "update.xml" file in the firmware. You'll see that there are specifications like "NOERASE" that basically mean "Don't flash this if it's a system update", and "FACTORY_ONLY" which means "Only flash this at the factory".

Here's an exaple from the XZ1 Compact firmware:

Spoiler content hidden.

The exception here is the "cust-reset.ta" file, which can be used to reset your radio customization. Since you're trying to enable VOLTE, you may want to keep the "cust-reset.ta" in your flash. If your provider is T-Mobile, this should trigger the phone to update the radio firmware to the T-Mo specific version.

Also note that, if you're using newflasher, the "partition" and "boot" zip files need to be extracted if you intend to flash those. Depending on how you downloaded the firmware, they may already have been extracted into their own folders.

Did you ever get this working with Mint? My XZ1 dual works perfect with my T-Mobile SIM, but when i use a Mint SIM Volte and Wifi calling does not get activated, it doesnt seem to prompt the phone to "optimize settings for this carrier" message.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Nice! I look forward to hearing from you by Sat-Mon then.

Honestly, if you go into Call Settings you should see VoLTE there IF it's available to use. If you can enable it too, then it's 100%. You don't need to see if Band 12 is being used b/c then you'd have to find an area that's actually using it, and that's much more work and not necessary to give us the answer we need. T-Mobile only allows Band 12 to get used if Band 2 & 4 (the main higher high spectrum bands) are not available. I got that confirmed a while ago.

Thanks!
[Sony Xperia XZ1  Questions & Answers] TX-Brad:
Been following this for a few days. I ordered the G8342 from Amazon on the weekend and received it Monday. Fingerprint sensor was disabled. Popped in my T-Mobile SIM and went to an area in town that I know is only covered by Band 12 (took my GS8 with me too). What I found, interstingly, is that the XZ1 was able to pick up Band 4 in an area that my GS8 is unable to. I put the SIM back in the GS8 and was on Band 12. Put it back in the XZ1, drove a little further north and the XZ1 switched over to Band 12 and stayed there.

I did decide, however, that the phone is too wide for me, so it has been returned. I did, however order the XZ1 Compact from a seller on eBay and it will arrive tomorrow. Will come back and update then.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Interesting. Maybe since the XZ1 is a little newer it's got better signal tech on it vs. the S8?

I wish you'd gotten a screenshot confirming the XZ1 had VoLTE enabled. But wow......... I don't know what to make of this. lol Let's see what racer has to say too. I don't know why it would work for you unless all the other publications were wrong and Android Headlines was right?! lolo
[Sony Xperia XZ1  Questions & Answers] 1230m:
So band 12 is indicative of VoLTE? I know band 12 is for LTE, right? But if it has band 12 that means it's "certified" (assuming that t-mobile would kick it off band 12 otherwise?)?
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
On T-Mobile's network, DEFINITELY. You cannot get Band 12 (and keep it) without VoLTE on their network.

Well you can get LTE with any 4G LTE band, like Band 2 & 4 (T-Mobile). So yes........Band 12 is a 4G LTE band too.

No. I WISH it meant that my friend. lol I had the Unlocked Int'l Xperia X Performance last year. It has Band 12, but VoLTE didn't even show up in Settings when I put my T-Mobile SIM card in. But a guy I talked to on here who had same phone but used AT&T said he had VoLTE. That is b/c AT&T DOES NOT require VoLTE-certification for customers to use it, but T-Mobile does. I know, what a hassle. lol So he had it, but I didn't. At the time I didn't care cuz my area didn't have Band 12 yet anyway. But that was 2016. lol As of 2-3 mos ago, my area (Chicagoland) now DOES have Band 12, and I WANT IT! lol My Unlocked HTC 10 has it cuz HTC got it certified, which was a MAJOR factor in me getting it over the int'l V20.

That is why this is so very strange. I want to see one more phone have the same results (nod to racer lol), but IF this is true, that means that the ANDROID HEADLINES article WAS right and the others who said only the XZ1C being T-Mo VoLTE-certified were wrong.
[Sony Xperia XZ1  Questions & Answers] 1230m:
Okay, thanks for the clarification.

There is another AndroidCentral article out today talking about how you can preorder the XZ1C now and it mentions it has T-Mobile VoLTE & VoWiFi. AndroidCentral already claimed this in another article, but that one (along with many, many that people have been sourcing) are from about a month ago, this is some newer news.

I've seen many people saying AT&T restricts much more? I assumed that was why I seem to come across most Xperia owners using T-Mobile.
[Sony Xperia XZ1  Questions & Answers] RockStar2005:
Sure no problem!

Yeah I really have NO doubt about the XZ1C having VoLTE & Wi-Fi Calling. But what I care about is the XZ1. lol

Hmm I dunno. I DID see a random review on Amazon (see below) I think by someone who has AT&T who says his XZ1 doesn't get VoLTE, so maybe they are more restrictive (unless you buy it through them)? lol I really don't know.

"B. Kateeb3 days agoIn reply toan earlier postReport abuse

I'm on AT&T and no VoLTE or Wifi Calling. I remember The Verge reporting that only the XZ1 Compact will support VoLTE and Wifi Calling and only on T-Mobile.

So honestly, who the F knows? I thought maybe he did something wrong, but maybe you're right and AT&T is just more restrictive? Ehh whatever. I don't have them anyway. lol
[Sony Xperia XZ1  Questions & Answers] VeixES:
I have taken look inside the Customized US firmware (G8342) https://xpericheck.com/cda/1310-4358 and call tell that tmous modem configuration(required for volte) is not loaded when you pop in tmous sim.

The configuration is there, but just not loaded. So there is possibility that it will get VoLTE in next update(s).

XZ1 Compact has everything is in place to get TMOUS VoLTE.
[Sony Xperia XZ1  Questions & Answers] 1230m:
Do you think they would update it to do so? I got the vibe that companies generally don't bother with certifying aged/aging phones? Not that this one is old by any means, but the last few years or so Sony has released new/updated handsets about every 6 months.
[Sony Xperia XZ1  Questions & Answers] VeixES:
I have no insight into Sony-s plans regarding TMOUS and XZ1, sorry. I personally would not buy a phone based on the hope of getting VoLTE in the future. I would wait month or two and check the newer updates if anything has changed. Probably by then you get price adjustments to sony phones also.

[Sony Xperia XZ1  Questions & Answers] RockStar2005:
I'm sure it does. It's just that we don't for sure if Sony certified the XZ1 with T-Mobile for VoLTE or not. We know the XZ1 Compact got it it seems, but there has been a discrepancy on the XZ1.
[Sony Xperia XZ1  Questions & Answers] hnt20:
Are you sure XZ1 compact got VoLTE on T-Mobile. I don't see any facts or user experience supporting that.
