What if I can't find the original x10flasher.jar file? I downloaded both flashtool and the patch, but after I install flashtool, I can't find any x10flasher.jar to replace. What am I doing wrong?

Perhaps not looking in the right place?
[Sony Xperia X Compact Guides, News, & Discussion] ilostmyandroid:
This worked perfectly on my Xperia XZ (USA, F8331) to get the fingerprint reader working without having to switch regions. Thanks!

Anyone having trouble switching regions or not wanting to deal with switching regions should try this method.
[Sony Xperia X Compact Guides, News, & Discussion] qvmuhuuxz:
I wouldn't recommend that method actually because it is not necessary to unlock the bootloader in order to flash a new rom (= flash a NON USA rom)

and by unlocking the bootloader you will lose your drm keys and thus lose a little functionality of your device (stuff like camera noise filter, uhh... not sure of all of them to be honest!)

If you back up your TA area first, then nothing to worry about.

But no need to unlock bootloader just to get the fingerprint working.
[Sony Xperia X Compact Guides, News, & Discussion] ilostmyandroid:
Ah nice clarification, thanks.

I already have an unlocked bootloader on my XZ to get root (and DRM functionality is restored via AndroPlus Kernal) so it made sense for me to try it. Just happy it worked!

Yikes, how come I am on Band 12 LTE in NYC? Can I "force" 12 somehow?
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
Flashed the UK custom version.

Issues so far:

1. LTE shows as 4G with zero bars (regardless of actual reception, same issue also in LTE Discovery app)

2. While band 12 seems to work, i don't believe that reception is as good.

3. Threaded messages with multiple people show up on their own threads.
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
Band 12 definitely does NOT work

for me after flashing the Customized UK rom.

I can get band 4 without problems but absolutely no band 12. Given that band 12 is the most prevalent T-Mobile LTE band, that is a big issue!

Is there a way to just flash the radio from the US rom? I am unlocked and have no problem fastboot flashing an image (or using recover to flash the radio).

Sony roms are weird and I have no idea how to get a radio image from all the crap that downloads via the tool.
[Sony Xperia X Compact Guides, News, & Discussion] piruzinho:
I got Band 12 for like 2 minutes here in NYC on tmobile.. Then not again. I really think it depends where you are. I would love to see something that 'guarantees' it more for sure.
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
I should be getting 100% (5/5 bars) band 12 reception.

That's what I had on my Nexus 5x and the previous ROM on this phone.

Band 12 does not work with the customized UK rom. Period.

I also noticed that I cannot turn on VoLTE (*#*#4636#*#* => Phone Info => enable VoLTE provisioning); even if it does not work with the carrier, I was always able to turn this on for every phone I have had.

Is there a way to just flash the RADIO image from the US rom? xperifirm downloads these weird files for the rom, and I can't find any guides how to extract the radio image from them ....
[Sony Xperia X Compact Guides, News, & Discussion] piruzinho:
I'd love to know, i'm on tmob. I cant be without that fingerprint, it is a lifesaver. If you can combine both, that would be awesome.
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
Flashed the US radio and got perfect band 12 reception back.

Do NOT use the UK rom with the UK radio if you are on T-Mobile.
[Sony Xperia X Compact Guides, News, & Discussion] piruzinho:
if i already have the "Customized UK" flashed... Do you have any instructions on how to flash US radio only? Thanks.
[Sony Xperia X Compact Guides, News, & Discussion] Staxman:
Did you not try the Customized CE1?

Seems to be fine for me X (F5121). Did an OTA update to latest (34.3.A.0.206) last week all good still...
[Sony Xperia X Compact Guides, News, & Discussion] svet-am:
Ditto on this for me, please.
[Sony Xperia X Compact Guides, News, & Discussion] bikoman1:
Just got an X Compact US version, it was running 34.2.A.2.47 US when I got it. I spent all day flashing different firmwares, CE1, UK, LAM to no avail. They flash successfully and boot, check version number and they are what I flashed, but never have I had a fingerprint scanner manager available, just not there? Any thoughts.........

I even went the route of unlocking bootloader after flashing 6.01 and using backupta_v2 to backup my TA partition. Downloaded EMMA and had it install the current Customized NOBA firmware.....still no fingerprint manager. I gave up and flashed my TA partition back and then had to use Xperia Companion to repair it because I got the dreaded "device does not pass verification". Now totally back to stock with DRM in place.
[Sony Xperia X Compact Guides, News, & Discussion] POMF2K:
Is there a guide somewhere?

Is there a guide somewhere that fully explains the full procedure to backup drm keys, unlock the bootloader, enable fingerprint sensor, root, and ensure all apps and functionality are retained, and will fully operate on t mobile us?

Every other Xperia xda forum seems to have one. Any ideas?

For those worried about TMo band 12, I flashed the German firmware (customized DE) and band 12 works fine on TMo USA. Not VoLTE I don't think, but band 12 data connection is confirmed with LTE discovery app. However, it is rare that I am on band 12, I suspect it prioritizes bands 4 and 2 over 12 for some reason?
[Sony Xperia X Compact Guides, News, & Discussion] POMF2K:
There's nothing in the title of that thread about enabling the fingerprint reader.

Also after reading previous posts I am concerned that the UK firmware will disable t mobile us band 12 functionality. Is that the case?

Oddly enough I'm in a band 12 region and cannot seem to connect to the lte network.
[Sony Xperia X Compact Guides, News, & Discussion] pleasepleasehelpme1:
please someone help its not letting me put my xz premium in flash mode
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
Further usage reveals that flashing the US radio over the UK firmware does enable Band 12, but it does not get used much and may have issues connecting.

My wife's Moto G4 will show stunning 4 bars of LTE reception on TMobile on Band 12 in the middle of nowhere, while my X Compact will show 0-1 bars of EDGE or GPRS internet.

Something clearly is not working properly. Searching for networks shows various TMUS 4G and 3G networks but the phone will fail to register. Switching SIM cards has the same result, so it is clearly the phone that is at fault.

I may try the LatAm firmware, though I am hesitant since it is a pain in the ass to remove all the crap (google and other) apps that I don't want for a clean ROM experience. I really wish that Sony provided better ROMs, so that one could properly export the radio image and flash it through fastboot or recovery.

Otherwise, this would be the best phone I have ever had.
[Sony Xperia X Compact Guides, News, & Discussion] Staxman:
Someone else on here tried LAT with good results IIRC. Im running CE1. Not as bad as UK, but not bad enough to loose fingerprint on my X....
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
Theoretically it should be possible to just flash the US modem/radio image but I f'ing hate flashtool which clearly does not properly flash the radio/modem.

I am with you on the fingerprint reader. I wish there was a way to hack the US firmware to have it working.

I am also wondering how well the LatAm firmware really works.

Reading through this thread it is obvious there are plenty of people who just take "it works in the big city" at face value, not realizing that it does NOT actually connect (or stay connected to) band 12.
[Sony Xperia X Compact Guides, News, & Discussion] camaro322hp:
While that may be true, I have confirmed via LTE Discovery that my XC will occasionally connect to band 12 (on German firmware, which also enables fingerprint scanner). However, as you have noticed, it seems to be a last resort - if ANY other TMo band is available, no matter how strong the signal, it seems favor those over band 12. I have seen my phone on bands 2 and 4 with relatively weak signals in places where I know band 12 is available and strong. Not sure if it's a function of the phone, network, or both, but it is a little frustrating.
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
That is exactly my problem.

In fact, it will prefer 0.05% GPRS coverage over 100% band 12.

If you go outside big cities with a lot of band 2 and 4, ie where it is great band 12 or ****ty edge/GPRS the phone essentially had no reception.

Also using LTE Discovery to verify these reception issues.
[Sony Xperia X Compact Guides, News, & Discussion] camaro322hp:
Curious - you mentioned your wife's Moto G4 gets great band 12 reception - is that an unlocked phone, or a TMo branded phone? My previous suspicions were that the TMo branded phones were given priority on band 12, and unlocked phones were basically never let on band 12 unless there were no other options. But if her G4 is unlocked, there goes that theory.
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
Her Moto G4 is just an unbranded, unlocked phone.

Outside the city last weekend she literally had 4/4 bars of LATE while my phone showed zero reception or just terrible edge reception which would stop every 2 seconds to no reception.

Searching for mobile networks on my phone showed various TMobile 3G and 4G nets but it would not connect.

PS: I reflashed the US radio over my UK ROM. No change. I may try latam version over the weekend, or flashing US and then just flashing Latam or UK system.

Can anyone with a US rom confirm whether that actually gets good reception?
[Sony Xperia X Compact Guides, News, & Discussion] camaro322hp:
I just thought of something - I'll bet it's because her G4 is VoLTE certified for TMo, while our XCs are not.

Here's an article that, while it is a bit old, may still apply to our current situation here. At the very least, it's an interesting read on band 12 and unlocked phones.

If it is really the lack of volte certification, then there is nothing we can do except spam the Sony forums and try to get them to certify the phone.
[Sony Xperia X Compact Guides, News, & Discussion] POMF2K:
Wait a minute... I thought these devices were working just fine on T-Mobile band 12 despite the lack of VoLTE?

I'm about to send mine in to Sony to see what is wrong with the LTE radio. Is there nothing wrong with it?

Mine is still stock. I haven't rooted or flashed the UK firmware because it won't connect to the band 12 LTE network. I live in an area with band 12 coverage (hence I bought this phone) and because it is unable to connect to that it always connects to T-mobile 3g, which as you know is very weak indoors causing it to hop onto an AT&T network. Thus I rarely have data indoors.

Funny thing though... when I took a trip to my old city (not band 12) it wouldn't connect to LTE either until I did a full hard reset.

So were those people claiming to get great LTE coverage with the x compact on band 12 lying? Should I even bother sending this in to sony?
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
If you re-read the thread it would seem that the device sometime connects to band 12. If there is any other network though, it will apparently not.

I don't know if this is a "per tower" restriction, or something else.

You should send your device in to Sony though, even if it just costs them money... Maybe we can get them to get the device certified. They recently certified some other xperia phones, and I am mad as hell that they forgot about the x compact.

I started a new thread about the VoLTE/Band 12 issue here:

https://xdaforums.com/general/general/lte-band-12-volte-t-mobile-t3658788

If you look around XDA, we are not the only phone with this problem and I hope it gets more visibility there.

I also tried enabling VoLTE by adding the relevant lines to my build.prop and enabling the setting in "Settings" and the phone=>info screen but that does not appear to make much of a difference.

VERY FRUSTRATING!!!
[Sony Xperia X Compact Guides, News, & Discussion] POMF2K:
You haven't dealt with Sony much have you? Superior manufacturing and design but awful marketing and customer service. I'll be paying to send it to them.

Thanks for the thread. I'll check it out. Have you formed a petition to Sony? You could post links in your thread and get everyone to sign regardless of the manufacturer they use.

Funny I actually stumbled onto the phone info settings but checking the volte and wifi calling buttons don't work. They just disengage after a few seconds.

Also, does the bootloader need to be unlocked to flash other firmware?

I've downloaded the UK, German, and US versions via flashtool but none of them show up in flashtool so that I can flash them. Only whatever x10 is and two firmwares from my tmobile branded xperia z3 that i've flashed in the past (obviously without unlocking bootloader).

Any ideas?

Maybe just a Flashtool bug? I'm at the latest version.

Well, it seems to work fine on my Mac at work. I didn't see the little expand arrow next to the firmware in the flash screen on my PC at home; I'm on a 4K display there and some older Windows UI components don't resize correctly for such resolutions, so I'm thinking maybe it was just too small to see lol

Is there anyone that has installed the European firmware that is on a version higher than 34.3.A.0.206? I installed the European firmware months ago to enable the fingerprint scanner. I updated to 34.3.A.0.206 in July or August when the update became available. I also recall updating the phone since then to a newer firmware. However upon looking at it today I see that it's on 34.3.A.0.206 when I thought it was higher than that. I recall installing both the August and September security patches. It's like the firmware rolled back on me and now it's not showing anything later available. Is anyone else seeing this?

I'm running Kubuntu 16.10 and everytime I try to create in flashtool it hangs. In terminal the last line reads: at gui.Main.main(Main.java:46) I'm guessing it's a Java issue, but I don't know how to resolve it.

Just tried this on a Windows computer and get the same hangup, so maybe it's a problem with the newest version.

In my experience 9 times out of 10 it's steps left out, which was the case here. Apparently you have to manually copy an extra file in(x10flasher.jar) in order to have the latest version.

Any chance we can get VoLTE working now that the xz1 compact is out and had it?
[Sony Xperia X Compact Guides, News, & Discussion] MissyVixen:
Pulling this back up as 2-3 posters also wanted more information.

**DO you mean you flashed the radio software files? Or do you mean you just Flashed the US System image again?

I looked at the Modem package from the stock US and UK roms and they seem to be the exact same size and signature, so if this the the baseband radio then there is no difference.

Could you direct us to the Radio Files if you do indeed have them?

--------------------------------------------

additional notes :

UK ROM at my house in BFE I'm pulling Down 8MBs and Pushing 5MBs Up. UK status Bar shows 0-1 bar. US Showed 1-2. I don't think the indicators really reflect much other than a semi relative indicator of strong or weak. Ive never found them to be that useful. It lists "4g" basically every where from out in the farmlands to into the major port area. I assume all the bands are working.

*UK rom I do notice that if I place a call while connected to data i drop from 4g (LTE stateside) to 3G (i assume this is HSPDA+ and not just "3g") -- Is this normal? I don't recall my previous LTE phones doing this, and i flashed the UK ROM to the phone as soon as i got it for the fingerprint reader.

Does this mean VoLTE is working on T-Maybe?
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
No. See earlier in the thread.

VoLTE didn't work and TMobile is actively preventing this phone from connecting to band 12.

Maybe with the xz1 out, sonstige can port VoLTE ...
[Sony Xperia X Compact Guides, News, & Discussion] Notchr302:
That sucks. I love this phone but I need the best service available as I use it to talk to customers for my business. Does AT&T play nice with the xz1?
[Sony Xperia X Compact Guides, News, & Discussion] MissyVixen:
Maybe so. I guess I'm shocked considering my blackberries don't have band 12 support, but did have VoLTE/HD voice and wifi calling support as the same radio file is responsible for both capabilities. One being the unlocked (q20 classic) and the other being a carrier locked (q10).

That said tmobile blocked the radio update for the q10 that enabled wifi calling and you had to side load a newer os entirely ( their Ota was actually older than the shipping os on their own branded phones to remove it) . They also stripped it from their q20 ota's about a year after the phones release. If you side loaded or stayed below their Ota it worked.

I'm not hip on new things : would VoLTE ported to the phone also allow wifi calling as it did in the past for other devices? I recall wifi calling working on my UK desire z after rooting and flashing a radio and app zip.

Maybe I should just jump carriers since tmaybe has so many issues and piss poor service where I live. I did not choose them, they just conglomerated my regional provider a long time ago. That said it seems the XC is not on any carriers VoLTE or HD voice capible devices list so it might be moot.
[Sony Xperia X Compact Guides, News, & Discussion] andTab:
The irony is that TMobile service is excellent if you have band 12/VoLTE ... Maybe even better than Verizon.

Their ducking shenanigans with VoLTE approval and blocking devices piss me off
