I'm on rogers too and I have no issue here in Vancouver, I was with fido last month and it worked like a charm.

In fact I'm still on 4.2.2 baseband, I've never flashed any 4.3 baseband and I still get lte.

Check the apn settings again,a typo might be the cause.

Edit: doesn't seem like all my screen shots got uploaded. I'll do it once I get home. . uploaded them

Method 1: make sure you guys flashed the baseband of 4.3 of C6506 or C6606 or try another FTF file if you have not done so already, see if that works if not try the following method.

Method 2: If it still doesnt work then Sony might have done something with the 4.3 update. If that is the case then do the following and hope it works. Flash back to 4.2.2 (everything) then boot the phone, then go back and flash the C6506 or whatever 06's "baseband only", boot it and then set the correct LTE stuff and see if you get LTE, if you do then go flash the entire 4.3 "excluding the baseband," boot the phone and you might have to set the LTE stuff again and see if you get LTE.

that way, you should be able to keep your 4.2.2 baseband and should be able to get LTE cause I have LTE here on Rogers.
[Xperia Z General] raylui:
C6506 4.3 tried, not working. not sure can C6606 work, will find one and try.

flash back to 4.2.2 require full wipe including data, would try after backing up!

Thank you so much for your advice
[Xperia Z General] airbus318:
For those curious. I finally upgraded my firmware. Went from 4.2.2 to 4.3

C6603_10.4.B.0.569

rooted. Decided just now I wanted my LTE back so I flashed the baseband same as instructed on page 1 post #9 using the stripped (Xperia_ZL_C6506_LTE_basebandONLY.ftf) file and voila, I'm back on LTE again.

For the record, the LTE for whatever reason WILL NOT work in my home city of Winnipeg BUT works in every other major city in Canada (tested in Toronto, Montreal, Vancouver and Calgary so far). I can't figure that one out. Something going on in Winnipeg with the network. This was always the case with this procedure for me.
[Xperia Z General] HellRoot:
But do you get LTE speed? I have heard from some that LTE shows but the speed are still equal 3G
[Xperia Z General] airbus318:
yup! I'm in Toronto airport right now with only 1 bar on LTE. 36mbps down and 3mbps up.
[Xperia Z General] airbus318:
Here's the proof, again in Toronto:
[Xperia Z General] jatyeo:
I'm an advanced user in Toronto running the ZR with 4.4.2, I've flashed like 5 basebands from various threads and CANNOT get LTE on fido with the lte sim and plan.

Please help, I need a ZL firmware for rogers or the baseband you flashed

Please and Thx

---------- Post added at 07:39 AM ---------- Previous post was at 07:32 AM ----------

Can you point me to that firmware or baseband pls thx
[Xperia Z General] jatyeo:
Hey any chance you still have that file kicking around?

Doomlords link is down

---------- Post added at 05:14 PM ---------- Previous post was at 05:11 PM ----------

Have you upgraded to 4.4.2 yet?
[Xperia Z General] athris:
For xperia zr I am not quite sure it work in this case, since it might be different hardware. The reason I could think of you can't get lte in Winnipeg because of the lte 2600 band is not deploy yet, so basically nothing you can really do.
[Xperia Z General] jatyeo:
Hey boss this link is down, can you mirror sommewhere thx
[Xperia Z General] iprisa:
I messed up my phone

OMG. I tried to flash my xperia z with C6506_10.3.A.0.423_Unbranded and I messed up my phone now it wont turn on. Any help please. I didnt check those options in the exclude section and flashed the device now it wont show anything. Only make 3 vibrations when I press the volume up and power key. Help please
[Xperia Z General] airbus318:
You might have bricked it. Can you boot into bootloader/recovery at all?
[Xperia Z General] Joshua Mr PC Repair:
Used this method with the Bell beasband and worked wonders for my custom rom
[Xperia Z General] jufece:
flashed and baseband stills 9x15A-ACEFWMAZQ-30110089-64

it didn changed.
[Xperia Z General] Epikarus:
Hi guys, I'm asking this for a friend who's one 4.4.2 and I was wondering if I flashed the baseband only from this http://xdaforums.com/showthread.php?t=2759110 would it work?
[Xperia Z General] shorinryu:
I tried flashing the C6616 Bell Canada baseband for the .230 firmware onto my C6603 running .283. I had no reception at all and had to reflash my stock baseband. Is this because the firmware versions are different and the basebands would be incompatible?

I figured that both devices have identical specs except for the modem bands so it should work.

Does this have to be done using a ZL C65XX firmware only?

I am using a C6603 Xperia Z unlocked on Virgin Mobile.
[Xperia Z General] iam breeze:
Can someone please upload a baseband only ftf please?

I have the C6603 and I'm only able to access 2G networks. When I switch to WCDMA or LTE the network icon goes empty.

I would really like to try the C6506 baseband, but it's a pain to download the entire firmware just to flash the baseband. Can someone please upload a baseband only ftf please?
[Xperia Z General] ikho22:
Give me a link of fw please.
[Xperia Z General] athris:
i don't have the phone anymore , sorry.
[Xperia Z General] LitoNi:
I dont think you did it correctly. It took me 1 sec to flash the basebands.

Did you follow the instructions?
[Xperia Z General] lhurtado:
Which LTE bands have Fido and Rogers? Here we have band 7 (2600) that it is supposed to be supported by 6603, but so far It didn't works.
[Xperia Z General] 100363086:
I had to reinstall the correct version of flash tool, thanks. settings and baseband is the same as yours however, I dont get any LTE service, Im in the Mississauga area (square one). I am with rogers. strange...
[Xperia Z General] Mr. Droid:
Anyone with bell test this ?
[Xperia Z General] G1_enthusiast:
just flash this on 6602...too lazy to go to an LTE spot, will test...whenever. still got HSPA+
[Xperia Z General] forzanerazzurri:
How the heck do you flash with the Xperia Z using this flashtool? There is no back button to press on this phone.
[Xperia Z General] athris:
vol down button, sony made this to enter flash mode since xperia s
[Xperia Z General] forzanerazzurri:
Thanks. Havent played with a flash tool since my Arc.
[Xperia Z General] EG8196:
Anyone tried it on Bell?

Thanks
[Xperia Z General] forzanerazzurri:
Holy crap this worked for me. I have LTE in Calgary on Rogers.. Genius
[Xperia Z General] 100363086:
It worked! However, im assuming that lte max uses the New 2600mhz band. And unlucky me, my house is in a pocket where theres no lte max but just lte. However my workplace in Brampton has it. Im only getting 1 bar of reception though, is that similar with you guys?
[Xperia Z General] athris:
I am pretty sure it is 2600. Since it had exactly same signal bar as my optimus g. I got 3 bar reception on my office.
[Xperia Z General] pkw168:
Got LTE now, thank you very much :laugh::good::good::good:

[Xperia Z General] pegasus5874:
I use flashtool to flash my C6603 and now my phone isn't booting up at all!! Please help!
[Xperia Z General] 100363086:
Did only flash the baseband?
[Xperia Z General] athris:
only flash the baseband, do not flash the anything else, since it is not same phone, it might brick your phone.

Try to flash the C6603 tft and see if u can get your phone back.
[Xperia Z General] forzanerazzurri:
After this can flash the .253 global lte update? Im still on .434.
[Xperia Z General] pegasus5874:
What can I do if I can't turn it on now? There is no light when it's charge and it won't start at all...help!!
[Xperia Z General] binku:
Flashed and this works amazingly. I am surprised how it worked!

I'm from Ottawa.
[Xperia Z General] Montague:
Don't worry I was too careless yesterday and had the same problem that you are facing right now. My phone did turn on though it's just the screen that didn't turn on (when I turned on the phone I felt the vibration of the boot only).

Simply just flash the 253 stock Rom or any other Rom you like. You don't have to wipe user data but just make sure everything else is flashed.
[Xperia Z General] LitoNi:
Please do follow the instructions here to avoid any issues.

and for those who got it working maybe post something like this:

model: ?? c6603 or c6602?

carrier: ?? rogers, fido, bell?

location: ?? city?

fw version: ?? ie. 253, 434

LTE status: yes or no?

may help others who are still wondering if it works or not.
[Xperia Z General] athris:
So glad, we can now enjoy the speed of LTE , no one need to call the tech support for telling us to change the apn setting lol :laugh::laugh::laugh:
[Xperia Z General] LitoNi:
lets hope it works after 4.2 update comes along. otherwise we might have to wait for 4.2 update for ZL to test.
[Xperia Z General] athris:
You could try, but i doubt it will work on US since at&t doens't have LTE band 7.
[Xperia Z General] EG8196:
Rogers or "Bellus"?

[Xperia Z General] grasshoxda:
im also in ottawa, rogers, c6603, on carbon rom.

[Xperia Z General] LitoNi:
its normal... usually if youre in a building/parking lot/elevator etc.. they have these things that blocks your signals or becomes weaker.
[Xperia Z General] Urbanos:
issue flashing!

man some days i hate computers... followed the instructions to the T - experiencing the same problem as this guy - i'm x64 win 8 pro - using flashtool x64 and the ftf .434 from the 6506

all went well until flashing - now stuck at 66%
[Xperia Z General] Urbanos:
Not sure if i'm supposed to just unplug the device and try again?? any advice?

***EDIT

tried the x32 flashtool, same thing, hangs at 66%....

downloaded tool 0.9.10.1

downloaded FTF C6506 .434 - placed in firmwares folder C:\flashtool\firmwares

plug in XZ to usb

open flash tool x64

click on firmware ftf etc

uncheck everything except baseband as instructed (very simple stuff)

flashtool says to power down my phone, hold down the back key (volume down button) and plug in

plug in to usb - zips through quickly gets stuck at 66% :( :( :(

unplug and try again...

***EDIT2*** kept trying about 4x now, always gets stuck at 66% - but this last time, when i rebooted, it seems to have taken (despite being stuck at 66%) - my baseband is the same as LitoNi's (9x15A-ACEFWMAZQ-30110017-11

i'll have to test it out and see - odd thing, it reset my keyboard preferences.
[Xperia Z General] lhun:
Telus

I'll be trying this soon for Telus and Wind. I have a c6603, currently getting HSPA+ 3g, but 4G LTE is available in my area.

On a super important side note, this baseband flash may allow Wind Mobile to work on this phone as well, as 1700/2100 is the same bands, but they use the "AWS" type.

I was successful in this trick by flashing a "combined" radio in my Skyrocket Galaxy S2. This allowed me to use wind, and telus, by simply swapping the sim. I've done this on a Hercules as well. If speed isn't as important as simply being able to use the sim, it works good.

If any of you are curious about learning more regarding this (I've done a lot of research, Canada is a lot different from America concerning frequencies) here's some information:

If you want to use Wind Mobile you can try flashing a T-Mobile radio.

T-Mobile USA	1700/2100 MHz, 1900 MHz	1700/2100 MHz, 1900 MHz	1700/2100 MHz	GSM/HSPA+	LTE (2013)

This only works for RECENT T-Mobile USA phones. The frequencies above are AWS for LTE, in GSM/HSPA+ only. AT&T also uses these bands, but they don't use AWS and therefore don't often work on Canadian networks.

850/1900 MHz for 3g on Rogers/Telus/Bell. However, Telus and Bell use the HSPA+ standard, so their radios will work both ways. Rogers operates on something else for 3g, so flashing a radio that disables that kind of connection may disable 3g or you may begin to roam in lower quality areas.

Telus is currently on a partnership with Bell for LTE services using GSM HSPA+ tech on 1700/2100 They use the same network. If your phone can do LTE with Bell, you can do LTE with telus and vice versa (including it's daughter companies Verizon and Koodo). If your radio is currently flashed and is capable of doing AWS, 4G LTE, HSPA+, and connects to 3g, your phone will work on EVERY CARRIER IN CANADA, which is the holy grail of being able to shop around.

:)

---------- Post added at 05:26 PM ---------- Previous post was at 05:21 PM ----------

If it works on Bell for LTE, it will work on Telus for LTE, 100%. They're in a partnership to provide LTE right now, it's the same network.

Im on Pananiodandroid AOKP ROM will this still work or do i have to be on a Sony ROM? Thanks! :D BTW i have a 6603! :D
[Xperia Z General] pegasus5874:
I tried to connect the phone to the PC using USB and even if I hold down VOLUME DOWN as suggested there's no response! When I looked at the log, it is saying my device connected with USB debugging off.

What can I do to let it flash? Anyone please give me some help! Truly appreciated.
[Xperia Z General] G1_enthusiast:
turn phone back on, go to setting--> developer option and enable it, then enable usb debugging, try the whole thing again (shut it off, unhook usb cable, go into flashtool, and set it up, click flash then when it pop up the screen plug ur stuff back in and press the down volume button.
[Xperia Z General] pegasus5874:
Thank you for your suggestion, but the BIG PROBLEM is.. my phone is in COMPLETE BLACK now! I don't even know where I am....
[Xperia Z General] Teknohtc:
how do i enter flash mode? I tried the back button + USB and Volume down + USB and doesn't want to connect.....BTW i am on AOKP panaiodandroid ROM. Also, the USB Debug is on.
[Xperia Z General] G1_enthusiast:
....wow you must have flashed something wrong... download a FTF and hope to god you can flash back everything to normal.
[Xperia Z General] athris:
hold the power button and vol up for 15 sec, charge the phone for 1-2 hours, it won't allow yo to flash if your phone is below 50% battery (i am not quite sure)
[Xperia Z General] pegasus5874:
I am SO STUPID... when I run Flashtool, instead of check those I should EXCLUDE, I just check Basband... so you know what happen.. EVERYTHING is flashed EXCEPT baseband....

Am I DOOMED? What else can I do? Do I need to call Sony for repair? Will they accept my phone for repair?
[Xperia Z General] LitoNi:
flash a respective C6603 .434 or .253 FTF file. dont exclude anything.
[Xperia Z General] G1_enthusiast:
It happens to me too when i try to flash to 253 kernel from doom kernel, I think you be alright just reflash everything with a 6603 tft
[Xperia Z General] pegasus5874:
Can someone please give me instruction how to flash it? Again I plug in the phone with the 6603 tft (HK) selected and when I click flash it just stay on the screen where it ask me to Hold DOWN and power...BUT it didn't recognize the phone connection...
[Xperia Z General] Teknohtc:
Ok i feel dumb lol thanks. Now i got a different problem the flash tool is now saying debug is off when it's on and i did activate the developers option by clicking the build number in the about phone menu. so it should work but, now it's being a pain in the A**! This should take 2 seconds now it's taking me an hour.... :mad:
[Xperia Z General] LitoNi:
Please do read the instructions carefully.

If you are using windows 8 please follow this guide to correctly install flashtool and xperia z drivers.

Most of you are confused with the word "exclude"

you are suppose to check "system, kernel, unknown, fota, partition" and uncheck everything else.

screen shot here:

Only way to find out is to try it and report back. Earlier someone tried it with carbon rom and it worked.

Please follow this guide

PS: i also updated the instructions, i hope its more clear now.
[Xperia Z General] gm007:
You need flashtool beta6 not this old one.
[Xperia Z General] Teknohtc:
never mind lol says exclude on the pic lol man i'm i stupid 2day! :D
[Xperia Z General] pegasus5874:
Surprise, surprise! I don't know what I did (try Up+Power, Down+Power, Power) but Flashtool start recognize my phone and I reflashed to the stock ftf and now it works!!!

Thank you all for your generous help. I still have one problem though... I tried to put my sim back from my iPhone5 using a sim adapter to Xperia Z and now.... it cannot recognize my sim.

Any help? I am ALMOST able to taste the fastness of LTE...
[Xperia Z General] G1_enthusiast:
your sim probaly broken go to the store and ask them to see if it still working.
[Xperia Z General] Teknohtc:
Ok this thing is making me mad now everything is up and running and still doesn't want to flash......:mad:

This is what i did:

-Enabled debug and developers options on phone

-Downloaded flash tool from link provided: http://xdaforums.com/showthread.php?t=2240614

-Installed tool

-Installed drivers

-rebooted computer

-Put ftf file in firmware folder

-select flashmode

-select ftf file

-Selected ftf and check/unchecked everything i needed

-picture comes up

-powered down phone

-pressed and hold vol down button

-plugged in usb cable

-aaaannnddd NOTHING!!!

All the drivers were successfully installed. This should be a walk in the park but, is ending being a pain in the A**! :(

On windows 7 64 bit using 64 bit flash tool 0.9.10.2beta6
[Xperia Z General] LitoNi:
are you using the latest flashtool? Did you set the correct settings for windows 8? Did you install the correct drivers for Xperia Z?

use this [TUTORIAL] HOW TO FLASH STOCK ROMs WITH FLASHTOOL
[Xperia Z General] pegasus5874:
I have that feeling too but when I put the sim back to my iPhone5 then it works fine...Xperia sometimes recognize I put the sim in and restarted but then it's still only stay in Emergency call only...
[Xperia Z General] Urbanos:
Voila. Just had to update the flashtool. Will post speeds shortly.

-64 bit flash tool 0.9.10.2beta6

-Installed flashmode and xperia z drivers via the flashtool drivers exe

-When plugged in it said SMEC drivers installed successfully

I do get an error saying: cannot run program "C:\flashtool\x10flasher_lib\adb.exe" create process error =2 the system cannot find the file specified

but, that's before the flashing it's when the program starts.....
[Xperia Z General] LitoNi:
Do you have pc companion installed?

When you run flashtool, please exit and terminate Sony pc companion and Sony update service if you have those running in the background

Does Flashtool recognize your device?

can you screen shot or post the logs?
[Xperia Z General] gm007:
All the threads here are fu**d up with how to use flashtool.

Anyway connecting the phone to sony update service will install the correct drivers for you.
[Xperia Z General] Teknohtc:
-OK did that

-Flashtool doesn't recognize anything

[Xperia Z General] gm007:
Use a pc with Windows7 to solve your problem.
[Xperia Z General] Teknohtc:
I have windows 7 and it's still doing this i don't know why this is soooo difficult :mad:

My computer reconizes the device and i have no idea why flash tool won't.....
[Xperia Z General] gm007:
Can you tell me which file or folder flashtool is not finding,the red line.

Or use flashtool beta4 and make sure to remove flashtool and its folder than install it again.
[Xperia Z General] LitoNi:
when you plug ur phone and open flash tool this is what youre supposed to see

Try using the older version beta5. it worked for me
[Xperia Z General] Teknohtc:
Not sure lol but downloading the same flashtool but from a differnt mirror might work out better if not beta 4 i will try. I have uninstalled and deleted the flashtool folder so it should be a clean install.

I happen to have 3 different SIM cards available for testing today.

carrier: Wind Mobile, Koodo, Telus Mobility

location: Windsor, Ontario

fw version: Global Unbranded 434 - just updated a few minutes ago, then flashed the ZL baseband.

Vancouver

So far max 36Mb down 6Mb up

Lte yes

I notice one thing though. Whenever there is a phone call comes in/or going out, it switches back from LTE to 3G/H+. After the call, it takes a while and switches back to LTE. Looks like the band 2600 is only used for data, not for the call...but who cares...the data speed is lightning fast now comparing to before! :)
[Xperia Z General] EG8196:
Does this mod. "enable" the AWS LTE band on C6603?

Thank you very much
[Xperia Z General] DooMLoRD:
can someone upload only the 3 baseband files (with loader.sin) and create an FTF for it?
[Xperia Z General] lhurtado:
This is correct, LTE is a data only technology. And use legacy network for voice and other services. This is called CS fallback.
[Xperia Z General] Mr. Droid:
Loving the speeds thanks for the find

Worth the extra cash to get the c6603
[Xperia Z General] Mr. Droid:
Anyone test this with cm ?

Does switching roms keep the baseband?

[Xperia Z General] rcyh:
Just updated to 253 and then re-flash the baseband from the 434 ftf. Everything (LTE) works perfectly as before.

This LTE mod is really awesome!!!!
[Xperia Z General] sipe1:
Somebody who has c6602 and LTE coverage can test it out? I can flash it but I don't have place to test it out.
[Xperia Z General] DooMLoRD:
here is just the baseband of C6506 LTE

no need to download full firmware ;)

can someone please test if it works?
[Xperia Z General] Mr. Droid:
Could be location as its spotty downtown.

Did you flash the baseband while on cm?
[Xperia Z General] EG8196:
this mod. seems doesn't "enable" the AWS LTE bands...

Because I can't get LTE in Ottawa (Bell)
[Xperia Z General] athris:
This phone (C6603) doesn't even has AWS Band, how could it be enable.......it is hardware, not software
[Xperia Z General] lhurtado:
Just for the record, following this idea I used the baseband from brazilian ZQ to get LTE working in Chile. :thumbup:
[Xperia Z General] Mr. Droid:
Bell is not aws

I'm on bell and getting lte maybe Ottawa doesn't have 2600mhz for bell
[Xperia Z General] EG8196:
Bellus are using AWS.

Btw, only GTA has both AWS, 2600 (Bell)
[Xperia Z General] G1_enthusiast:
I thought there is 4 files in the baseband, yours only have the loader.sin

For people with bell wondering if those will work for them you can go to bells lte coverage map and click the 4G LTE radio button and then the 2600 MHz areas are the cyan coloured of up to 150 Mbps. I cant post a link because I don't have enough posts.
