[Q] Flashing c6602 frequency bands on c6603?

Hi all,
first post here on xda. not sure if it was asked - is it possible to flash the frequency bands from c6602 on a c6603? or some type of software hack that will allow the c6603 to use the c6602 bands?
thanx

Why would you want to do that for what reason ?

I'm here in the states. Figured it may be easier to flash then to sell this model and buy a c6602. Was thinking about changing to T-Mobile that's all.

Flashing bands doesn't give the phone frequency bands. It's a hardware thing, flashing bands from 02 to 03 doesn't do much as 03 bands are fixed.
You may bring up how come 03 can enable lte by flashing c6506 bands. Well the answer is that 03 has those bands to begin with, it just grant access for it to connect to certain frequencies.
In conclusion, it's a hardware chip, flashing bands doesn't give the phone frequency bands.

why dont you post this in the right section?
just flash it and see...its not gonna crash your phone if u know what your doing with flashtool

Sorry will post in correct section next time. Thank you. Still learning Sony and flashtool. Coming from nexus devices. one last? , o can flash the 6506 in the 03 and activate US let bands?

i do not think the states have the correct bands to match it. i think someone tried it already with t-mo.
works for canadians..

actually it may work for your device, 6602, i try it yesterday but dint work, I'm not complaining with 15mbps down and 3 mbps up...the download is more important, I can stream music, watch youtube 1080p fine.

So the c6603 and c6602 and C6506 do not have the same bands in it internally/hardware wise? My understanding is that they do. I am on tmobile in the states with the c6603 and I am checking on here everyday looking for a us tmobile c6603 thread but all i see is the canadians working miracles across the border. My question would be if we could flash the c6506 in the states on c6603 would that allow us any lte? or should I just wait till the end of the yr when they finish hspa+?

C6506: LTE 700 / 850 / 1700 / 1900 / 2100
C6603: LTE 800 / 850 / 900 / 1800 / 2100 / 2600
C6602: Doesnt have LTE bands. It has the same chip as C6603 but its deactivated or whatever. I dont think flashing C6506 baseband will work.
Flashing 6506 baseband on 6603 in the states, I dont know will it work in the states. LTE frequencies/towers locations are different for every country and carrier. LTE isnt out at all locations, just cause one band is supported doesnt mean the other ones are supported.
Only way to find out if it works is to flash it and test it out.
It works for canadians cause most LTE used by carriers are 2100 and 2600.

If you flash a 6506 baseband to a 6603, will you gain 1700 and 2100 for HSPA+? Or is there a hardware limitation? Having support for HSPA+ and (possibly) LTE for Tmobile & AT&T in US is very appealing.
6602 has HSPA+ support but lacks LTE ability since it doesn't have the bands. Must be a hardware limitation.
6603 has LTE support after flashing the 6506 baseband for (possible) LTE US support but lacks 1700 and 1900 for HSPA+

By chance is there a secret code accessible by the dial pad to access the frequency or radio bands to activate or switch between bands?

[Q] C6906 baseband on C6903/C6943

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.

i would really love to experiment, I just dont want to loose all my data and root :? there is no generic version of .534 for the c6906 which is exactly what I need to keep root and all my mods.

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 finally did it...

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.

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.

C5306 4G in Australia?

I'm a bit of a noob when it comes to mobiles phones and I just bought a Xperia SP C5306 from the US. I am located in Australia and am wondering if I can use the 4G here back at home? I kinda bought it in a rush. If there is no way I can use the 4G because of the difference in frequency bands can I some how change it with a kernal or rom?
Cheers

C5302 and C5303 (LTE) are definitely compatible with Aussie network bands, but the C5306 is for US network bands. I don't think that you can change the frequency bands, I think that it is a hardware thing.

Ah dang. Guess I gotta some how get rid of the phone to someone in the US since the C5306 does not accept the 4G LTE bands here in Australia. Thanks for the help.

Can c6906 work on LTE frequency 1800?

I have a Z1 C6906 which is the Canadian model. It supports 1700 LTE but not 1800.
Where I live, our LTE network is 1800mhz, but my phone doesn't connect to it.
My question: Is there a way to somehow enable that frequency on my phone? Is this purely a hardware incompatibility? For instance, can I flash another baseband to enable it?
Thank you
