Xperia Z C6602 LTE band IV AWS possibility

[paperWastage]

We know that the C6603 has LTE, while C6602 doesn't

http://www.gsmarena.com/sony_xperia_z-5204.php



Take a look at the FCC website.


-- evidence that FCC website shows a C6602

From the External Photos.pdf, first page, bottom photo, the photo says "C6602"



From the Label.pdf, it says "C6602"



-- evidence that LTE could be possible

From the Internal Photos.pdf, page 4, bottom photo, the Qualcomm chip says "MDM9215M", which supports LTE FDD/TDD CAT3, SVLTE-DB and it is the same modem that the Nexus 4 had. Nexus 4 had that LTE hack for band 4 AWS

On page 3, bottom pic, on the chip near the bottom right, there is an Avago A5004, which is a power amplifier supporting part of LTE band IV(1700mhz portion)

Above the A5004 chip, there is the Qualcomm WTR1605L transceiver(also present in Nexus 4), which supports all LTE frequencies in the world right now





Recap, chips listed supports LTE band IV:
Modem: Qualcomm MDM9215M
Power Amplifier: Avago A5004 (only 1700mhz, not 2100mhz for LTE band IV downlink)
Frequency Transceiver: Qualcomm WTR1605L
Antenna:? can't tell from FCC photo

Now, we don't know if the above chips have their full functionality and active, or whether there is a power amplifier for the 2100mhz downlink, or whether the antenna supports it, or whether we can find a software mod to enable LTE Band IV signal. Can't find a full Xperia Z teardown, and the FCC pictures aren't detailed enough

Had a telephonic discussion before purchasing Z in India. They said it has LTE and some bands on which it will work. LTE (Bands 1, 3, 5, 7, 8, 20)* Same information is posted on Sony India Website as well. Model is C6602.

Everything says it is 4G LTE..... Even national Gadget show "Cell Guru " Aired on Saturday conforms the same. I have the screenshot as well the video.

The white paper on that Sony site you linked for c6602 doesn't say anything about lte

http://www-support-downloads.sonymobile.com/c6602/whitepaper_EN_c6602_xperia_z.pdf

Most likely they were mixing up the c6603 and c6602 version


Also, the c6602 only has the band IV LTE chip in the photo.. Will Sony actually create a c6602 v2 with band 1, 3,5,...) LTE, or the c6602 in the fcc filing had a dormant second modem chip for band 1,3,5...LTe

Edit: actually, I'm not sure which exact LTE bands the 9215m supports... Could also be bands 1,3,5..

 

[paperWastage]

according to the C6603 white paper, it also uses the 9215M chip... so i wonder what Sony left out in the C6602...

So, does Xperia Z support LTE IV band? Is there any way to activate or only HSPA+

 

[st3v3n_lee]

Onyone try flash with 6603 latest firmware? 6602 have lte netwotk selection if you flash with 6603 firmware

Yes, but I can not choose it. If I choose LTE it just switches back to previous.

I hope this is true!! That would be really awesome!!

I flashed my 6602 using 6603 latest build. I got in my network selection lte (prefered) yet I can't get lte. Signal my provider addressed the my mobile should support 1800 not only 2100.

Any idea.

I really hope someone can find a hack for LTE much like the Nexus 4. After all, they use the same chips.

 

[Riyal]

Hey uhm... Have you also flashed the baseband other than the firmware? Amplifier is the antenna and modem is the same it should hardware wise be capable of recieving LTE signals once radio firmware is compatible.

Judging by your explanation seems like your current baseband doesn't support LTE yet since as you said it returns back to HSPA/GSM when switched to LTE in which only means it's a software block.

 

[SmoothSal]

Very interesting! This would be phenomenal.
even though I already own c6603 version.

 

[HoOnZ]

Huge news!

We might not have the baseband to support the LTE now, but I'm hoping when T-Mobile USA start selling the XZ we can. Hopefully we can use the baseband from the T-Mobile branded XZ to enable LTE on the C6602. *crossesfingers*

 

[Macjad]

Now that t-mobile is selling the Xperia Z hopefully we can try to enable the LTE on the AWS band

The specs on the sony site for the Xperia Z model C6606PL are:
UMTS HSPA+ 850, 900, 1700, 1900, 2100 MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
LTE Band IV

I hope this model has the same parts as the C6602

I'm hoping that it's as easy as flashing the C6606 ROM on the C6602/3 and enabling the LTE chip.

If only it were that easy. LOL

LTE Software dump

If I have the Tmobile phone with me, what can I do to extract the software so others can try to import it to the C6602 Model.

Will pos the FTF Today

I will post the FTF today, and let me know if anyoen else can try it on their C6602 models.

Does anyone have the FTF already so I dont have to do it again.

I don't think so. At least I haven't seen it on XDA yet.

I don't think this will work anyway. Someone who flashed C6603 firmware to his C6602 told this:

*In service menu, it shows model C6603
*In service menu, the working bands shown are GSM850, GSM900, GSM1800, GSM1900, UMTS_BC1, UMTS_BC2, UMTS_BC4, UMTS_BC5, UMTS_BC8

On my real C6603, working bands are GSM850, GSM900, GSM1800, GSM1900, UMTS_BC1, UMTS_BC5, UMTS_BC8, LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20.

So apparently, cross flashing does not change working bands. Perhaps the supported frequency bands are stored in the Trim Area (TA), just like SIM locks.

crack

Who is going to crack this issue. One way or another we need to know
