It's been figured out, I speculated it was possible, and it is!
Preamble
Hi everyone. As we know, the C6603 (all country versions) can be swapped with the radios from the ZL. This allows you to get LTE on Rogers and Fido in Canada, and I assume would work for other carriers as well in other parts of the world. (this is due either to unlocking frequencies, or unlocking channels on those frequencies.)
The radio HARDWARE is the same. *(?!? is it?) From what I understand the baseband chip in ALL the devices is a:
Qualcomm MDM9215M
which fully supports all the bands we can possibly use. Meaning, this device CAN use UMTS 4 1700/2100 for T-Mobile and Wind and Telus etc etc.
The secret is the amplifier chips. If the c6603 has the amplifier chips physically that the c6602 does we should be able to do the same trick that was done on the nexus 4. A modification of the build.prop may allow for AWS networks to work on our c6603. We can only hope. Partial support to at least use the AWS bands should be possible for the 6603. You would have to do the same thing that was done for the google nexus 4. Essentially,
#!/sbin/sh
echo "telephony.lteOnGsmDevice=1" >> /system/build.prop
echo "ro.telephony.default_network=9" >> /system/build.prop
echo "ro.ril.def.preferred.network=9" >> /system/build.prop
And then flash. Obviously requires a rom cook and root. If any intrepid developers wants to give this a shot, I suggest using the 6606 baseband, as it seems to be both a 6602 and 6603. The 6616 is essentially the same as the T-Mobile phone but with Canadian channels.
Why I care
When the Z first came out, I knew I needed to have it. By a terrific stroke of luck a local had bought an unlocked international Belgum phone off ebay and decided he wanted the S4 instead. He was selling it for hundreds below the MFG price on Kijiji. I immediately bought it. I love the phone, but I can only get 3g, as I am with Telus, and the phone "doesn't support" officially, AWS on Telus. Works with HSPA+ for whatever reason though, on non aws bands.
New knowledge not currently found on the forum
Bell uses AWS on HSPA+ as well as LTE. So does Telus, and Wind. (and Tmobile in the US)
Historically, only the C6602 has the frequencies needed for the other carriers. Bell, in Canada, recently released the C6616.
(LTE compatibility AWS, 700 MHz HSPA/UMTS compatibility 850/1900/1700/1900/2100 MHz GPRS/EDGE compatibility 850/900/1800/1900 MHz)
The question with no answer.
The question is: Can I apply the Baseband file from the Bell C6616 phone to get AWS 1700/2100 hspa/LTE on a C6603?
NEW!
Note: I'm not rooted, nor am I bootloader unlocked. Neat, eh?
Here's what basebands I've tried so far: (c6603 Generic BE, .67, 4.2.2)
c6506 US .434, c6506 US 0.423 - both work perfectly on 4.2.2, no issues. On Telus you can only see Telus, and AT&T, sometimes Rogers.
c6606 - Phone boots, unusable. Random reboots, locks up immeditely after swipe to unlock. Simply flashed baseband back to c6506. - This may be because I was using a 4.1.2 rom. I'm going to re-investigate.
c6616 - Phone boots, slightly usable. Random reboots, even in airplane mode. System.process freezes but eventually unlocks. If you screenlock, you need to reboot. Flashed it back to c6506 (probably due to 4.1.2 again)
ZL c6502 .434 global unbranded - Phone boots. RADIO SHOWS - (!!!) Phone completely usable. OMG I CAN SEE BELL 3g and ROGERS LTE (which is 2600mhz!). Something interesting is going on here, but it's not unlocking any additional bands in reality. The *#*#service#*#* menu shows the same frequencies available - but there's CERTAINLY some modification to the ranges in the bands. For those of you using .434 c6506, switch to c6502 global, you might get better speeds. Woot!
Z c6602 .67 Works. 2g, 3g bands including LTE (on 2600 only I'm sure) available but only on Rogers my home network, Telus, comes up as 3g H+. Cannot see Wind but that might be due to not having a wind Sim at the moment T-Mobile comes up as 2g only. I believe it uses umts 4 for 3g/4g. Essentially the same as c6506.
c6606 0.191 - phone slightly usable. Still has issues with random reboots. Won't go into info or network menu at all. This sounds like mismatched build.prop... this might be possible. Exciting.
MORE MAGIC FOUND. The info menu (*#*#4636#*#*) *#*#info#*#* allows you to swap country mode frequency ranges (including an UNKNOWN range on)!! This greatly impacts the available networks you see when you scan for networks in the phone. With USA selected I do NOT see T-Mobile, for example, when previous I did. Needs more playing.
Here's what I found out:

No worries, I really know what I'm doing here. I'm doing a baseband only flash.
Looking into flashtool, the recognition=C6602,C6603,C6606,C6616,L36h,yuga keys exist. Meaning, flashtool SHOULD see the c6616 in the list, but yes, it doesn't. (?!?!)
I recently grabbed C6506_10.3.1.A.2.67_Generic US, and it works flawlessly as thje previous c6506 basebands on 6603's did. On Fido, it'll give me LTE, obviously, but that's due to 2600 I'm sure. but only gives me 3g (hspa+) with Telus. (non aws).
According to the service menu, The phone only supports the following, even with the 6506 baseband flashed (screenshot is from my phone just now):

8 Up: 880 - 915 Down: 925 - 960
20 Up: 832 - 862 Down: 791 - 821
AND YET, the T-Mobile C6506 is supposed to support:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
4G Network LTE 700 / 850 / 1700 / 1900 / 2100
Okay. So if that is the case... HOW IN THE HECK are some of you people getting LTE on Bell?
Bell's (and Rogers/Fido, Telus/Koodo) LTE network uses Band 4 Advanced Wireless Services (AWS 1700/2100 MHz: actually 1710–1755/2110–2155) in most coverage areas and Band 7 (2600 MHz) in a few areas.
Wind's and Telus's is 1700/2100 (AWS1) only. THE ONLY WAY I can see this working is because bell/rogers has UMTS 2600 in the GTA. HOWEVER: Why weren't we getting LTE (data only) in the first place on the 6603? It supported LTE 2600 from the start. It's a very good question, and one that could be because of the sub channel bands used for LTE on HSPA+. What's interesting, is that since this phone supports Band 3 and Band 1, you can SEE the LTE/HSPA+ AWS1 network, but it doesn't stay connected (Because you can't split negotiation bands... UNLESS, you could limit one antenna to one and one to the other (not sure it's possible)).
That's seems to be the ONLY reason it works on Bell/Rogers in some cases with the 6506 2600mhz baseband. You're not getting true AWS with that flash (which can be for hspa+ or LTE). Also, the c6616 appears to be a more complete radio that would literally work on every single network in Canada and the USA, being the "ultimate LTE" Xperia Z. The c6602 Internal Storefront phone is the closest original thing, to that I would imagine.
Oh, I forgot to mention, I did try the T-Mobile 6606 baseband on the phone. It causes a soft lock after booting sadly (which does get into the OS, but it locks up and goes black once it's there.), and you have to flash back to either 6506 radio or stock to get it to stay stable.
So no, I do not believe this phone can be "told" to use AWS, regardless of what baseband file you stick in it. Now I'm not so sure. The same thing that was done on the Nexus 4 should work here.

I'm not sure it will work at all, apologies if this has been explored. The phone only supports limited UMTS bands. In particular, it would need to say UMTS 4, 9 or 10 in that list, I think.

This is correct, sort-of. It turns out that the radio hardware chips themselves are actually the same, but the unit is missing the physical amplifiers for the frequencies you would unlock, making them impossible to use. It's the c6603 radio hardware that has euro LTE. However, the 6602 is supposed to support AWS in some fashions. If you flash the baseband from the bell Z, you may be able to use AWS 4, because it's not just the frequencies that you make available, it's the CHANNEL SET.
In summary a "baseband" is three things
1) radio driver
2) frequency range list
3) channel range list
In theory (logically), the baseband from the "unbranded sony store" phones of each hardware model variant should have all the carrier frequencies of the local area.
So, if you're from Germany, flashing a the Sony "carrier unbranded" baseband from the local model variant should allow you to be all all carriers in that region because it would be in Sony's best interest to sell an unlocked phone in that region in that way.
It gets dicey when you bring a phone from another country as I did, into a country that uses different radio frequencies and channels for the same wireless protocol types. It's complicated and has to do with the radio telecom standards differing in every country. True "World Phones" are really uncommon but we're getting more standardized every year.
I still own my Z but I also have a Z1. The Z1 is a LOT more compatible (every carrier in my area) because it's designed to work with local frequency sets. All I had to do on it was flash the Sony official firmware and baseband, and I could get LTE on every carrier.

Only way to find out is to flash the baseband and see what happens, if not you can always flash back to stock C6603 baseband.

Unless of course, someone can provide a baseband that "unlocks" UMTS 4, 9 or 10... And, that the radio is physically capable of doing it.

As i see from different firmwares, some overlay applications might deny to use some of capability of phone.
In over my firmware testing experience, some off firmwares prevent to use single 3g, and some of them prevent to use mixed network.
You must sure you have totally generic firmware. Try to delete all overlay apks, those might restrict you to configure network coverage.
PS:
I'am going to flash C6606 fw 10.3.1.E.0.191 to my 6603 afew later.

Hi Eryen, thanks for replying!
If you read through my post, I tried that and it did not work. Gets to the OS and locks up. However, we're just swapping signed basebands. We need to figure out which radio hardware they're using to see what it's capable of, and perhaps, we can start making custom unlocked drivers.

So I'm starting to think the 6603 could be hacked to get umts band 4 in the same exact way the nexus 4 was.
If I get more time I'll try this out - I would rather it be possible without root but meh.
To contribute.
I have C6602, flashed C6603 baseband, tried with 4G card in confirmed zone of 4G signal, only catching 3G.
Will try with C6502 baseband when I have again 4G card.

I'm not sure it will work at all, apologies if this has been explored. The phone only supports limited UMTS bands. In particular, it would need to say UMTS 4, 9 or 10 in that list, I think.

I'm deeply grateful with you and your work, i don't know if you are a developer or just a guy who got a Xperia Z and wants to enable some features that's been banned from sony and of course making us the job to reroute this, even harder than nexus 4 disabled LTE feature, i have just 1. question, i own a Xperia Z (C6602) i'm on existenz 6.6 ROM wich is based on official 4.3.
I have understood that XPERIA Z C6603 and C6602 version both bring along the exact same LTE chip BUT sony disabled this chip on C6602 version for an unkwon reason yet, i've read around so much about it, and i concluded, that the chip on C6602 was disabled by some modem modifications,
how can i enable LTE feature?
if i flash C605 modem will work and get LTE?
i am from colombia and my carrier is TIGO (german company) they uses AWS band 4 for LTE speeds
any help from you and yor knowledge, sorry if i bother you with this but i need to make clear this hole in my head once and for all dude
THANKS in advance

The C6602 does not have an LTE capable radio. I'm not sure where you heard that it does, but that information is incorrect. There is no way for you to use LTE on your device, no matter which baseband you may flash.

This is correct, sort-of. It turns out that the radio hardware chips themselves are actually the same, but the unit is missing the physical amplifiers for the frequencies you would unlock, making them impossible to use. It's the c6603 radio hardware that has euro LTE. However, the 6602 is supposed to support AWS in some fashions. If you flash the baseband from the bell Z, you may be able to use AWS 4, because it's not just the frequencies that you make available, it's the CHANNEL SET.
In summary a "baseband" is three things
1) radio driver
2) frequency range list
3) channel range list
In theory (logically), the baseband from the "unbranded sony store" phones of each hardware model variant should have all the carrier frequencies of the local area.
So, if you're from Germany, flashing a the Sony "carrier unbranded" baseband from the local model variant should allow you to be all all carriers in that region because it would be in Sony's best interest to sell an unlocked phone in that region in that way.
It gets dicey when you bring a phone from another country as I did, into a country that uses different radio frequencies and channels for the same wireless protocol types. It's complicated and has to do with the radio telecom standards differing in every country. True "World Phones" are really uncommon but we're getting more standardized every year.
I still own my Z but I also have a Z1. The Z1 is a LOT more compatible (every carrier in my area) because it's designed to work with local frequency sets. All I had to do on it was flash the Sony official firmware and baseband, and I could get LTE on every carrier.

Actually it's not exactly true. There is a custom kernel mode driver that locks this radio from using the other frequency bands. It may be possible to cook a custom driver that enables them, but the amplifiers might not be there, although I suspect they are just like the Nexus 4. The reason they are strongly disabled is because enabling them in a country that uses those channels and frequencies might break their local radio telecommunications laws and it would not allow them to sell the device in the country with the radio being "un neutered". That's one of the reasons why pushing these things through the FCC can take time.
So, am I correct or not? You said I was in post #17 and not in post #18!
If it's kernel related, then surely flashing a C6603 kernel would bypass it (which it doesn't)...? Correct me if I'm wrong, as I'm only an interested amateur.

Truth is we don't know for sure because nobody has done it, we're talking about writing a custom driver which is different.
Qualcomm MDM9215M
which fully supports all the bands we can possibly use. Meaning, this device CAN use UMTS 4 1700/2100 for T-Mobile and Wind and Telus etc etc.
The secret is the amplifier chips. If the c6603 has the amplifier chips physically that the c6602 does we should be able to do the same trick that was done on the nexus 4. A modification of the build.prop may allow for AWS networks to work on our c6603. We can only hope. Partial support to at least use the AWS bands should be possible for the 6603. You would have to do the same thing that was done for the google nexus 4. Essentially,
#!/sbin/sh
echo "telephony.lteOnGsmDevice=1" >> /system/build.prop
echo "ro.telephony.default_network=9" >> /system/build.prop
echo "ro.ril.def.preferred.network=9" >> /system/build.prop

I have the GT-I9305N, which apart from the standard 1800 and 2600 MHz bands available on all 3 phones has the 900 MHz band activated in place of the 800 MHz band available on the GT-I9305, whereas the GT-I9305T seemingly has only the 1800 and 2600 MHz bands.
So is the LTE chip in our 3 phones the same chip or are there different variants? And what is the point of the GT-I9305T if the only difference is it has one band fewer than the other two, I mean why not just sell the GT-I9305 in that case? Wouldn't that make more sense out of a manufacturing aspect? (fewer variances means fewer configurations and less work for a manufacturer, I hope this is obvious to people)
I mean unless the point is that the GT-I9305T should only be usable on carriers which have networks with the correct frequency bands supported, making re-sale less likely. That is literally the only possibility I consider likely. What are your thoughts?
Nobody knows anything about this?

Probably there is some legislation about low frequency bands in Australia, I don't know... But AFAIK i9305T was made for Telstra Australia, as i9305N was made for Sweden where Tele2 (COV) and Telenor (Voda) are working at the 900 and 2600 spectrum.
http://forum.xda-developers.com/editpost.php?do=editpost&p=39798979
Source about the networks: http://en.wikipedia.org/wiki/List_of_mobile_network_operators_of_Europe
I haven't looked into it but don't really think there is much difference. I have the 9305T which from what I have seen appears to be a Telstra only model as I think both Optus and Vodafone in Australia sell the 9305 (I may be wrong but remember seeing Optus with 9305 not 9305T). I have not tried a 9305N rom but both 9305T and 9305 roms work fine on the 9305 only difference lately is signal strength. Status bar reads one bar less if using a 9305 modem. I am pretty sure the 9305T would have the 900 range active as Telstra use both the 850 and 900 range.
I do remember reading some time ago that Telstra are a bit more picky with testing the phone on making sure the software is more suited to their network and being Australia's largest telco provider I think may have sway over some manufacturers who are willing to make multiple varients to get what they want. Just my thoughts could be wrong

I'm not from Australia, so i cannot say much about your telco providers. But here in Brazil i only saw the GT-I9305T been selling by Claro (wich includes mine). As i could search, Claro works with the 850Mhz (3G) , 1800Mhz (GSM/GPRS/EDGE) and 2600 MHz (4G).
On Brazil - as the site from Claro says - 4G only works yet with the range 2,5GHz - 2,69GHz.
== Sorry the bad english ==
For those that buy a GT-I9305T with Telstra firmware and try and use it on another telco's network, calls and SMS will work but MMS and Data will not due to the CSC.
The solution is to download the stock Australian Firmware and use Odin to flash
For example
PDA: I9305TDVBMB1
CSC: I9305TTXSABMB2
The symptom is the missing H+ etc in the status bar next to the signal strength bars.
My phone is GT-I9305T, will it work the same if I flash the GT-I9305 rom along with RIL + modem from GT-I9305T?
I have a gt-i9305N
I think the N stands for Nordic, I live in Sweden and have Tele2
And I have only flashed the rom. No need to flash your radio if it already works fine.
Flashing CM rom won't touch your radio and rightfully so.

I used a i9305t with stock Telstra firmware on the Optus network for a little while before I rooted it and changed roms. Data worked fine...

I know this thread is old but incase anyone else is wondering. Its the modem thats different, the 9305T runs on Australian frequencies and adds the 850 band which is Telstra NextG network.
Hope this helps.

Yes. just flashed the german 4.3 ROM on my I9305T - even the 4G data worked, but data speeds improved greatly when I flashed my carrier's current baseband/modem.
The hardware in the variants are the same, it is just a carrier/manufacturer agreement to limit non-carrier provided firmware.

I agree fully. I too have a GT-I9305T LTE from Telstra. I had the 4.1.2 firmware running. I too downloaded the latest Jelly Bean 4.3 for GT-I9305 from Germany (I9305XXUEMKC_I9305DBTEMJ4_DBT). I honestly had my concerns. Compatibility for the network being one of them. I did alot of research and decided to take the plunge. All done and I am more than happy with it. The dowload speed jumped from about 6mbps to 60 mbps. Not sure why but I dont really care its faster than broadband that I'm stck with at the mo. Anyway. GT-I9305 firm works fine in a GT-I9305T.

OK, I did a crap load of research on this earlier in the week because I'm in the process of buying a few I930x phones for the family via eBay.
My understanding is that the hardware is identical but the ROMs in use on each version may affect network operability.
The issue gets clouded because data you find here and there on the interwebs tends to have conflicting information about the phone's specs.
Regardless of what specs you read on GSMArena or elsewhere, the ROMS for phones that Telstra and Optus provide are customised for their requirements.
The hardware may be identical to the that described elsewhere on the web, but the software isn't necessarily so. ROMs for the i9305 and the i9305T are also customised by other network providers around the planet, and thus may differ from the vanilla "International" versions.
I'll restrict my reply to LTE (4G) here, as all variants of the i9300 and i9300T appear to be compatible with 850/900/2100 3G UMTS spectrums used by the three Australian networks.
Both Telstra and Optus currently operate 4G on the 1800 spectrum.
However, Optus operates additional 4G on the 2300 spectrum for its "4G Plus" customers - see Optus's notes at optus[dot]com[dot]au/network/mobile/4g
Telstra does not operate on the 2300 spectrum and has no requirement that its handsets operate there. Hence, I would be surprised if Telstra feels any desperate need to incorporate access to the 2300 spectrum in its ROM.
On the other hand, Telstra has "... also been using some 2100MHz spectrum to provide extra capacity on [their] 3G 850MHz network using the latest generation of network radio equipment known as Software Defined Radio. As the number of LTE devices that are capable of LTE2100 increases, [they] can simply change these cells from 3G to 4G-LTE via software. This will help [Telstra] manage 4G capacity until [they] get...new spectrum. See Telstra's notes at exchange[dot]telstra[dot]com[dot]au/2013/05/07/mobile-spectrum-auction-result/.
So, both the i9305 and the i9305T will work on the 1800 spectrum, but the i9305T may or may not work on the 2300 spectrum and the i9305 may or may not work (for 4G) on the 2100 spectrum.
Theoretically, the i9305T is also optimised for the specific band within the 1800 spectrum that it needs to operate on. However, in practice, the handsets are tolerant enough such that this is not an issue.
Handsets provided by Telstra and Optus will definitely work on the relevant spectrums their respective networks utilize. i9305 devices provided by third party providers require investigation on a case by case basis.
However, the situation is about to become more complex.
At last year's ACMA auction both Telstra and Optus bought additional bandwidth in the 700 and 2500 spectrums for expansion of their LTE networks. See Telstra's info here exchange[dot]telstra[dot]com[dot]au/2013/05/07/mobile-spectrum-auction-result/ (again) and ACMA's info here www [dot]acma[dot]gov[dot]au/Industry/Spectrum/Digital-Dividend-700MHz-and-25Gz-Auction/Reallocation/digital-dividend-auction-results.
In the Telstra link provided above, Telstra also says "Firstly we’re seeing new devices that support the LTE900 MHz band (another low frequency band) so we’ll use this in areas where coverage and capacity makes sense. We’ll also deliver Australia’s first LTE-Advanced network and devices using LTE900+1800" and "We’ve also been using some 2100MHz spectrum to provide extra capacity on our 3G 850MHz network using the latest generation of network radio equipment known as Software Defined Radio. As the number of LTE devices that are capable of LTE2100 increases, we can simply change these cells from 3G to 4G-LTE via software. This will help us manage 4G capacity until we get the new spectrum."
So, in the not-too-distant-future, Telstra 4G devices will operate on bands in the 700, 900, 1800, 2500, and possibly 2100 spectrums, whereas Optus 4G devices will operate on bands in the 700, 1800, 2300 and 2500 spectrums,
A summary is here mobilenetworkguide[dot]com[dot]au/australian_mobile_phone_frequencies.html"]here[/URL].
The big question then is how are customers going to get firmware upgrades so that there devices can take advantage of the spectrum changes.
It would be reasonable to assume that Telstra and Optus will provide updates for newer devices they have provided. However, neither will provide firmware updates for devices acquired from elsewhere. Optus ROMs won't take full advantage of Telstra's network, and Telstra ROMs won't take full advantage of Optus's network. Other ROMS may or may not provide access to all the relevant bands,
So, Telstra may provide updates for i9305T units it has provided, and Optus may provide updates for i9300 devices it has provided. In order to receive these updates you will need to be running the appropriate Telstra/Optus Australian ROM on your device.
Devices acquired from 3rd party providers, whether they are i9305T, i9305, or anything else, will probably be left out in the cold.
You could, of course, root your device and load a suitable ROM that way. I could do it, you may be able to do it, but 99.5% of people out there would not be able to do it. And I really couldn't be bothered to do it on multiple handsets.
So for peace of mind, given these imminent changes I'm sticking with Telstra branded i9305Ts. It just seems to be easier that way.
PS to mods. I saw the message "To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages, yada yada yada" However, I'm not spamming and the information I have linked to is on-topic, but it is obviously too voluminous to incorporate into the post. Hence I have taken the liberty of modifying the URLs of the links as a compromise, so that they are not hotlinks but people can still find the sources. I don't mean any disrespect. It's just that I went through this exact same process earlier this week, and found the source information to be really helpful

Hello all!
I saw that Xperia Z owners got LTE working when they flashed Xperia ZL baseband on their devices... So I was thinking about:
LTE Bands for C6903 & C6943: 800 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600
LTE Bands for C6906: 700 / 850 / 900/ 1700 / 1900 / 2100 / 2600
My country (Brazil) have LTE working at 2600MHz on great cities, but roads and small cities will get 700MHz LTE (less expensive... bigger distance between cell sites and all that technical stuff).
I own a C6943, if I flash the baseband of C6906 on my Xperia Z1 will LTE works on both 700MHz and 2600MHz?

will someone help us with this? im too scared to flash the entire ftf onto the phone i have a c6903 i need the c6906 for at&t capabilities. I flashed just the baseband and nothing happened. i think you need the full ftf for any type of action really..i just dont want to mess up my phone right now its important to me
You can try it, but the physical modem may not be capable of (or calibrated for) the other frequencies.
It's safe to flash full FTFs - unless you interrupt it or let the battery die, the worst thing that will happen is a soft brick, which you can fix by re-flashing a working FTF. I have read about some people doing the opposite (accidentally flashing 6903 onto 6906, or 6902 onto 6903) and they only lost some channels or 4G, but were able to flash back.
This is a new device, you're probably just going to have to experiment.

Since you have root, you can TiBu or use recovery to make a complete backup, mess around, then restore when you're done. Guess it'll come down to how much you want LTE
I have a C6906 and I've been looking for a generic 534 - it doesn't exist and probably never will. I've only seen the Rogers 534. Since 534, you can uninstall all their bloat anyway, good as you'll get.
I wouldn't worry about ftf breaking your phone if you flash the wrong version. I've mixed baseband with other region ftf before with my xperia ion. In order for lte to work, I need to keep the Rogers/North American baseband on my rogers xperia ion, but I flashed a generic nordic ftf (kernel and system only) in order to get jelly bean. Combination of best of both worlds.
The reason why the Z works with the ZL baseband is because both phones support 2600 and Rogers has the 2600 frequency but for whatever reason needs the setting from the the North American baseband for everything to work correctly. There must be something slightly different with international 2600 and north american 2600. I doubt 700 will work since the c6943 doesn't support it. Also dont forget (at least up here in Canada) you need both a LTE sim card and possibly new lte APN settings for LTE to work.
I dont think you need full ftf flash either... otherwise how would my xperia ion combo work? Also its running cyanogenmod at the moment... cyanogenmod is kernel and system only (it doesn't touch baseband). As long as you have the lte sim and correct lte apn it should just work.

Quick question about your idea, i want to flash a custom rom on my Z1 (the rom is 6903 based whereas my z1 is 6906). I already did and Lte works but signal is at least 2bars weaker than with 6906 rom. So what i can do is to flash a 6906 Tft, then flash over the 6903 rom while excluding baseband (to keep correct modem drivers/modules)?
Thanks for your feedback.

The true test would me someone flashing the C6906 baseband on C6903 and test if 700MHz LTE is working or not. I can't test it because here in my country 700MHz LTE isn't deployed yet.

I did that and got better LTE speeds (average 33.5 Mb) than on the standard C6943 or C6903 (17-25 Mb) FTFs.

The speed is relative, as I said, the TRUE test is make a C6903 or C6943 work on 700MHz LTE, which my country (Brazil) don't have (yet).
I understood that, just said that despite the "correct" and "tested" C6943 ajusts the C6906 baseband works better. I also live in Brazil and I know we won't see the 700 mhz band anytime soon as they'll only be auctioning it later this year.

True story. And most manufactures seems to be neglecting the fact that Brazil will have 4G at 700MHz in less than 2 years (in the current rhythm), I can't see even one LTE phone on Brazil that works on 700MHz and 2600MHz.
There are phones that works on both bands (like C6906 or D6503 from Sony, Asian version of HTC One (M8), one version of Lumia 1520), but these models aren't the models sold on Brazil.

Yeah, I've got my eyes on the HTC One (M8) if for some reason the Z1 stops being good enough, but getting the asian model won't be so easy as the us or europe variants would be. If I'm not mistaken the only phone sold in Brazil that sported the 700Mhz band was the iPhone 5 and that only served to make people whine about no (local) 4G in the device lifespan.
Xperia Z1 (C6943) + CM12 = No LTE
Need help. Have a Xperia Z1 (C6943) with Official CyanogenMod 12 and can't get 4g connection.
Have already played with the network configurations without success. Tested my simcard in a Xperia Z2 with Sony firmware and it got 4g connection.
Don't know what else to try and don't wanto to move back to Sony's firmware.
Any ideas?
I put c6906 firmware on my c6903 and it worked. Question is, How will i know if the extra band is working for at&t.. It still gives me h+ in most areas I dont get it. any insight?

The firmware Works but you cant use 6906 LTE 700 band, because is hardware related.
the difference in z1 models are the LTE modem and the 6903 don't have the same as the 6906.

@mrled is correct, the LTE support differences between C69xx models is 100% hardware, so flashing other FTFs will not help.
C6903: LTE 800 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600

In Canada, a C6903 will have limited LTE on Bell, full LTE on Rogers & Telus, but no LTE on mobilicity/SaskTel/Videotron/Wind. 2G/3G support is identical on all C69xx models.

It will only be a soft-brick, completely recoverable via flash mode (unless you do something stupid like run it low on battery or unplug the cable at the wrong time).

Do they use the same frequencies in Canada as in the US? In the US, they use 700/1700/2100, and I think 1700/2100 (band 4) is their primary (most widely deployed). If that's true for Canada as well, all four phones should work on LTE. Obviously, I have not tested this so I cannot be sure.
Flashing a 6906 to a 6916 for wifi calling feature
Hey Guys!
I bought a Sony Z1 last year (6906) Canada boot loader locked to use on T-mobiles LTE network and everything worked great, only issue was I lost my Wi-Fi calling feature on the new model as it was not directly from T-Mobile and really liked the feature.
I see that T-Mobile released an almost identical version (6916), only I think has more memory and less bands available.
I tried to pull the wifi .apk file off my original android phone to see if I could make it work, and would not install assuming brand specific of permissions related.
so, wanted to pick the forums brain and see if any one out there has done this, take the firmware for a T-mobile branded 6916 model ( I believe current version is 14.2.C.0.159, until new kit kat release comes out if and when of course ) and put it on the 6906 model so the wifi calling feature can work.
Bands look to be there, so hoping this could work unless someone had a reliable work around for the Wi-Fi calling ?
Please excuse my noobness, new to Z1 forum so any and all help greatly appreciated
Thanks for any help in advance!
I thought bands and signal reception were hardware related not software related.

I live in Sacramento, CA and it's supposedly a refarmed city, meaning it uses 1900Mhz spectrum on T-Mobile for 3G. So I bought a C5306 for my wife, however the 3G isn't working, all we get is EDGE. Naturally I thought I'd at least get LTE, since it's advertised as an LTE phone but I'm not getting that either, even though we have LTE in my area. What's the deal? Has anyone else had this issue? In the phone settings I have it setup to receive LTE/GSM/WCDMA in that order but it doesn't seem to help.
The 5306 claims to have the right bands...
HSDPA 850 / 900 / 1900 / 2100
LTE 850 / 1700 / 1900 / 2100
I'm calling lies on either Sony or T-Mobile...

It's a 5306. Otherwise it wouldn't have LTE listed in the baseband options when you type *#*#4636#*#*
EDIT - I take that back, I guess the 5303 does also have LTE, but different bands. God I hope it's not a 5303, how can you tell? Different ROMs come from different bases and depending on the ROM you install it'll say 5306 or 5303. The stock ROM that came installed on it said 5306, but I installed another custom one and it now says 5303, ugh.
Holy ****, not only do I have the wrong phone, I think I was defrauded in the process. This is a 5303 that was sold as a 5306. The seller just flashed 5306 firmware on top to make it look like a 5306. The picture below shows that it has the 5303 bands (1,3,5,7,8,20) and not the 5306 ones (1,2,4,5).
Does it say C5303 at Model Info? Or on the Box? If yes get your bud to the store

It says whatever firmware you put on it. The C5303 and C5306 firmware are interchangeable. Hence why I think they can sell them as "C5306" phones. This was on ebay, by the way. The only way you can tell is to look at what bands the phone supports, which I did above, you do that by typing *#*#7378423#*#* in the dialer and then going to Configuration in the Service Menu.
i have a c5306 i checked the bands. Anyways i am using it on att and i get h+ but no lte any ideas?
Hello guys, as you can see I'm a new one on this forum, just joined a minutes ago,
but frequently looking on here for Q&A about previous phones I had.
Ok, so basically I got a Xperia Z (C6603) unfortunately my carrier is Nii digital s. de r.l. de c.v, known as
''NEXTEL'' my data plan consist on HSPA+ & 3G, I'm not so experienced on this, but as far as I know,
this carrier runs on HSDPA 1700 / 1900 frecuencies, very compatible with another devices bounded to T-Mobile.
My last phone was an Moto X (XT1053 Custom Roms based on T-Mobile stock), didn't had any single problem with it,
I just wanted the elegant Xperia Z.
The Moto X it's fully capable to get HSDPA 850 / 900 / 1700 / 1900 / 2100 for 3G.
But my C6603 it's only capable of HSDPA 850 / 900 / 2100, since NEXTEL would run only on the 2 left missing from this one,
I've made a bit of research and then I said, so if 6603 is LTE capable the another variant 6602 should be able to get
a complete set of 3G frequencies HSDPA 850 / 900 / 1700 / 1900 / 2100, those are the ones that I need,
I'm not really interested on 4G or LTE networks for this mobile.
It's just that at the moment the device is practically useless for me, so by reading and looking on this forum I was able to
discover that this device is essentially the same one as the 6602, just with the hardware mods to get LTE.
I've downloaded many FTF's, flashing only the basebands of another roms, including ones from the ZL 6506, 6502, etc...
This didn't brick the phone, stills... No signal on the phone, the baseband didn't even changed on system info, I modified the build.prop too with something like...
#!/sbin/sh
echo "telephony.lteOnGsmDevice=1" >> /system/build.prop
echo "ro.telephony.default_network=9" >> /system/build.prop
echo "ro.ril.def.preferred.network=9" >> /system/build.prop
And then flashing the different basebands...
(if there's a better detailed tutorial on this, should one of you guys be able to teach me the right way?)
So I was wondering if I should flash a complete FTF of the 6602 to get the phone working on a fully 3G network?
I'm not really interested on high speeds or LTE, just need the phone to be working on these frequencies to be able to make use of my carrier's plan that i'm paying atm.
One curious thing, if I use the same SIM on a xperia ZL, it gets wide signal almost around all the city.
I'm quite frustrated right now, hope any of you guys can help me with this.
Thanks!
(Sorry for my bad english though)
Device info:
Stock 4.4.2 (10.5.A.0.230)
Unlocked bootloader
Sim-Unlocked
Good battery health, not a single issue, it works fine with Telcel, Movistar & even Unefon Sim Cards.
-----------------------------
Uploaded an screenshot, I've just flashed a complete 4.1.2 stock rom of the 6602... No luck so far,
can any expert on the field, help me please?

The Cellular frequency which a phone can operate depends on the MODEM which is a hardware component
You will not be able to tackle this issue by flashing 6602 firmware
''Qualcomm MDM9215M''
Both variants share the same exactly hardware, just programmed many hardware limitations I guess for the 6602 to only work on HSPA,
6603 didn't had those limitations so it can operate in LTE bands, as far as I know.

You need the 1700/1900 bands ,no?
But your phone doesnt have the chip to receive those bands hence no network coverage...
Simply, if you want it to work you can get the motherboard of a faulty C6602 and put it in your phone, which is real expensive and not worth it.
