[Q] C6603 not having 4g option (UK) - Xperia Z Q&A, Help & Troubleshooting

Hi,
Hoping someone can shed some light on this odd problem I have. I'm on EE in the UK which is at moment our only 4g provider. I smashed my old S3 LTE screen so my girlfriend (Who is on 02) upgraded early to an xperia z, which we were assured is 4g compatible. We had to unlock the phone to work on my network of course.
However, after unlocking I don't have the option to change to 4G in the network menu.
I've checked the following:
The phone is the C6603 model, which I double checked supported the bands and frequencies used by EE
I receive 4g in my area (Used to with old phone)
I checked with 02 that the phone was 4G compatible
However I'm guessing it's been turned off in the software that 03 loaded to customize the phone. I can't for the life of me find any info on the internet on how this is done or reversed, and I'm a little hesitant to flash the ROM as I would be murdered should I brick the thing.
Any ideas? Anything appreciated.

I flashed the Spanish 4.2.2 ftf file onto my UK 3 Z.
That gives me the option to use LTE networks. You might have to do something similar to get yours to pick up a LTE signal.
Did you say the phone was from O2?
Its also a piece of piss to flash ftf files. You don't even have to root or unlock the bootloader.

Yeah, phone was got from 02. I suspected that there's something loaded with the bloatware... Hm, so I guess I need to try flashing and risking the wrath of the girlfriend should it go up the swanny..

Dial *#*#4636#*#* and in phone information there is an option to change to lte,try it.

Now this is odd, I had the option when I went in there... But it flicks straight back to WCMDA Preferred. I also just rooted it.. so I'm confused now.

So better to do what warface suggest.

[Q] i9305N LTE not working

Hi there! I'm sorry if there already is such a thread but I couldn't find anything quite like this.
I bought this i9305N second hand and it had the famous IMEI problem 00/02. I went to a service center and there they were able to restore the IMEI of the device. And the phone was able to connect to the 3G as normal but not the 4G network. I've never seen the 4G working on this phone and have no idea what to try. What I tried was:
different modem firmwares.
flashed CM 10.1 and again tried those modems.
tried to set the phone to lte only via the *#197328640# code.
I think that in Sweden this phone is supposed to work on only the tele2 and telenor 4g network. I've tried sim cards from both operators.
Has anyone experienced something like this? Does anyone have an idea what is happening and what I can try?
Thanks in advance.
Does yr provider support 4G?yr sim card support 4G? If all above Yes then yr area doesn't support 4G or the coverage of 4G very poor till none.

my operator supports 4G. There is 4G coverage and I've tried cards from every carrier here on contract and prepaid.
Try a phone wipe and install the stock firmware for your network .

Just out of curiosity, have you tried cards confirmed to be on 4G-enabled contracts? I had to call Tele2 and ask them to change my contract over to a 4G one before I would receive 4G speeds. Another silly thing you could check is if the phone is actually connecting to the 4G APN, for Tele2 this would be 4g.tele2.se.
Hi! This is the thing! I havent found a card with confirmed 4G on it. I was told that sim cards on contract have 4G enabled on them. I was wondering if there is some sort of a tool to scan networks around and see information about them like what freq and speed etc... I am using my comviq card now in the phone with the apn that you mentioned and that was set automatically as the phone is with the tele2 firmware. The most brutal thing was when I went to the tele2 office and asked for a 4g activated sim to try on my phone and they said that they don't have any!!!! I went to the telenor shop and when I asked for a demo sim card with 4G so that I can test my phone and he gave me a 3G prepaid card. After 10 minutes of changing settings and stuff on my phone I asked him if that card has 4G on it at all he said - no, its just a 3G. I am going a bit of topic but my point is that it is extremely hard for me to find out where the problem is.

My point is how are you planning to use 4G on the phone if you do not have a 4G contract? I mean, why all the fuss if you cannot use it anyway?

I want to be sure that the phone works on 4G after the reparation before getting a 4G contract.
Find someone with a 4G contract and ask to test his SIM in your phone.
I had a friend enable lte on his contract and then tried the sim on my phone. LTE didn't kick in. I don't know what it could be. Any suggestions please?

Hi.
I live in the "kära grannlandet" Finland and i had to call my operator to put my i9305 as my active phone.
(They change the ownership of the phone on their computer)
I bought my phone 2hand but it was factory sealed new. operator locked to the same operator that i use.
The phone was "active" to somebody else without 4G so thats why it didnt work for me.
Hope this helped at all..
Lycka till!
My friend had similar issues with his S2, I went into the phone options menu using the #xx# number and the phone itself was not set to lte mode. I am sure you can find the menu codes somewhere on the forums as I don't have them memorized. It is worth checking if you have not done so.

Possible to pick up AT&T LTE?

I was playing around with my T-Mo Z C6606 for over a week.
Yesterday, I decided to flash it with new rom 10.3.1.A.0.244 Generic ES.
I rooted it and it worked properly.
After reading a post about enable LTE in Canada, I decided to flash my Z with C6506 baseband.
Everything is going good and it shows my Z now supports LTE_BC1, LTE_BC2, LTE_BC4, LTE_BC5, LTE_BC17 while stock rom only supports LTE_BC4 for T-Mo LTE. AT&T LTE is LTE_BC4 and LTE_BC17.
However, my Z is still not picking up LTE. I also read that I need to call at&t to update imei to make it connects to LTE.
I called them and they added my Z imei but so far, it is still not picking LTE signals, only H+.
I am not sure if ZL baseband doesn't work with Z or something else.
I appreciate your comments.

I did research and know that t-mobile use band 4 (aws or 1700/2100) for LTE, while at&t use both band 4 and 17 (700) for their LTE.
My Z is now showing it has both bands 4 and 17, but it is still not picking up LTE.

OK, it's ZL baseband issue. I just put t-mo SIM back in and it is not picking up LTE either. I reflash back stock baseband and it picked up LTE right away.
I may have to wait for someone with C6616 would like to create ftf and upload it.

It works only on one of 3G bands of ATT. Take a look at the map to see if where you live is working well with that band. When I travel I get awful service in places with this model but where I live it works pretty decent. If you have a c6602 though I belive that is pentaband and should work on every 3G band.

How about flashing a C6602 or C6606 or even C6616 would that allow me to get at least in hspa+ service on att or t mobile? Or can't I change the bands on the phone with flashing a different model ftf?

I did and only found out C6616 on Bell doesn't have Band 17 either.
I have downloaded FTF of C6616 on this forum too.

Mine is also factory unlocked, but I paid for it. You can check your service configuration by enter a combination key *#*#7378423#*#*
You should only have LTE_BC4.
Without LTE_BC17, you can't pick up at&t LTE.

I am not sure if they have changed their procedure for what phones they allow to use the LTE bands, but from what I read you need an imei of an AT&T branded phone to get them to change your plan to allow LTE access(doesnt't affect the price of your plan) , then you may use a different phone provided you have the proper apn and it supports AT&T LTE bands(which you are uncertain of at this point). Does your AT&T plan online say it's the LTE plan? I currently have the developer version of the HTC One and people had issues getting LTE access on that phone (this phone definitely has AT&T LTE bands) and people had to resort to using a imei of another AT&T branded LTE phone in order to get access to LTE. I previously had a ATT Galaxy Note 2 and when I got my HTC One I just popped the sim in, never called them, and have been fine since.
Yes, I have 4G LTE Plan on my number as it was on my previous Xperia TL AT&T version.
I also did call them and request to add my Z IMEI and they told me they did. However, I couldn't get LTE so far.
One more thing, I also can't get t-mobile LTE with C6506 baseband firmwares unless I reflash it with stock t-mobile baseband (LTE_BC4 only).

in my area the coverage is perfect and i use my sim card on another device which is supporting 4G LTE and it works. my provider is Omantel and they using frequency range in 18000 MHz.
however, i had tried some rom to upgrade my device to 4.2.2 jelly been and i successfully upgrade my device and still i had problem with 4G LTE.
i had use RUU to return my device as stock. now it is running on 4.1.2
is my device supporting 4G by knowing the model?
is it possible to have in the setting LTE option and the device not supporting 4G ?
if my device is supporting 4G ,how can i change the carrier frequency on my device?
our country's 4G frequency range is 18000 MHz

I would hope not either. I love mine, but you could try rooting it and putting a custom Rom on it. There's s chance it could he an issue with your kernel too. And if that doesn't work you can unroot and just send it back.

IIRC Omantel is in the middle east. I'm not sure where you got the phone, but I believe you actually want a stock phone who's MID is PN0710000. This seems to be the appropriate model for Europe/Middle East which has LTE (4G) support for 800/1800/2600.
The PN0712000 supports LTE on 700/AWS. This the the current model I have over here in Canada.
Hope this helps.

I just got a new Xperia SP (C503) that is factory unlocked. I am currently using it on Walmart Family mobile (T-Mobile) plan but I can only get Edge data connection speeds. Is there a way to get 3G on this phone on the Family Mobile network.
Have you tried adjusting the network settings found in settings/more/network mode then set it to wcdma preferred(gsm)
Once changed a reboot will be needed.
If you have done this then maybe somebody else can help

C5303 isn't compatible with T-Mobile for 3G or LTE. You could get 3G on AT&T, or if you want to stick with Family Mobile you would need the C5302 to get 3G.
Have a look at gsmnation.com to check compatibility.

Help with getting kit Kat LB roms working on my C6606

I have had trouble getting any of the roms here going on my phone. Coming from a long line of evos and galaxy's I am no stranger to rooting and modifying. What the hell, at least I am rooted and Happy with the nova launcher, almost good as a Rom.
Now I see kit kat is out for locked bootloader phones. Is there anyone that doesn't mind running down how to upgrade a c6606 phone without any surprises?

As far as exact process I would be interested in that too.
As for availability, either grab the ftf fir your region or wait for a rooted flashable Rom.
As far as the rest goes, t mo has been pushing app updates so we may get something.

I'm also curious, if I follow the directions in either of those threads will T-mobile LTE still work? That's the only problem I could see occurring since the c6603 and c6606 are almost identical aside from the radio bands. If anyone has already tried it please let us know, thanks.
It should work. I just flashed 4.4 earlier today on my c6606. Works fine. No longer says 4G but instead says H+. If anything you can keep the TMo baseband when you flash the kernel.

Go to settings>more>network mode select lte option.
it will display the relevant logo where you have 4g coverage
think you have wcdma option enabled
I did that as soon as I flashed the ROM. I have LTE set as preferred. I get either R for roaming, 2G, 3G or H+.

H+ is HSPA+ not 4G
Guess the place you are residing has 4G signal issues
Correct, the signal here is kinda funny. I get 4G but not 4G LTE here.

I ended up installing the update coming from the latest T-mobile firmware and excluding the baseband when flashing the tft file. Everything seems to be fine for me, I still get LTE speed only now the icon shows up as "4g" rather than "LTE" but that's fine. Out of curiosity does anyone here use the T-mobile Isis app and if so do you know how I can get it to recognize the phone as the T-mobile variant thus allowing me to use the app? I've tried replacing all instances of "c6603" with "c6606" in the build.prop to make it match the what was there in the original firmware, but I've had no luck.
