[HTC One X] joobie:
Hi Guys,

I have a HTC One X (Quad-core model) and am trying to flash to a custom ROM. Below are some details about the specific model I have..

cid: OPTUS001

version-main: 2.17.980.4

HBoot: 1.12 S-ON

Recovery ROM: CWM

I'm trying to go with a popular custom ROM, but not having much luck with this. I did bump into CyanogenMod, but this requires HBoot to be version 1.28 and from what I can tell, this is not possible with my CID.

Are there any other popular custom ROM's that are compatible with my phone?

Cheers, joo
[HTC One X] Mr Hofs:
I would suggest to return to stock if you are not and update to jellybean first and then going for a custom rom. Your choice of custom roms to use is now limited because of the hboot version
[HTC One X] joobie:
Thanks Mr Hofs.

Why is it better to go to stock, upgrade to jellybean and then look at going custom?

Also are there any popular custom ROM's that you know of which would be an option for me?

Cheers, joo
[HTC One X] tomascus:
You can either go back to stock and it will automatically update your hboot through OTA or manually flash new hboot (easy if you can follow basic instructions).

Popular ROMs? I guess have a look at the number of views on each thread? But popular or not, try them all out and see what YOU like. Once you upgrade hboot you can use any ROM

Edit: Optus released JB update in December, you're a few months late
[HTC One X] Mr Hofs:
what tomascus says ! :thumbup:

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
[Xperia Z General] TechGuru_x10:
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.

http://www.sonymobile.com/in/products/phones/xperia-z/specifications/#tabs

http://www.sony.co.in/pressrelease/asset/550442/section/corporatepressreleases

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.
[Xperia Z General] paperWastage:
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..
[Xperia Z General] paperWastage:
according to the C6603 white paper, it also uses the 9215M chip... so i wonder what Sony left out in the C6602...

http://www-support-downloads.sonymobile.com/c6603/whitepaper_EN_c6603_xperia_z.pdf
[Xperia Z General] sipe1:
So, does Xperia Z support LTE IV band? Is there any way to activate or only HSPA+
[Xperia Z General] st3v3n_lee:
Onyone try flash with 6603 latest firmware? 6602 have lte netwotk selection if you flash with 6603 firmware
[Xperia Z General] sipe1:
Yes, but I can not choose it. If I choose LTE it just switches back to previous.
[Xperia Z General] Smartphoner:
I hope this is true!! That would be really awesome!!
[Xperia Z General] mohdsos:
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.
[Xperia Z General] vx117:
I really hope someone can find a hack for LTE much like the Nexus 4. After all, they use the same chips.
[Xperia Z General] 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.
[Xperia Z General] SmoothSal:
Very interesting! This would be phenomenal.

even though I already own c6603 version.
[Xperia Z General] 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*
[Xperia Z General] 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
[Xperia Z General] HoOnZ:
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
[Xperia Z General] qkabierta69:
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.
[Xperia Z General] Apollo89:
Follow this guide (part B, C and D): [GUIDE] Download ANY firmware customization from Sony & create an FTF with Flashtool
[Xperia Z General] qkabierta69:
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.

---------- Post added at 12:55 PM ---------- Previous post was at 12:44 PM ----------

Does anyone have the FTF already so I dont have to do it again.
[Xperia Z General] Apollo89:
I don't think so. At least I haven't seen it on XDA yet.

---------- Post added at 07:05 PM ---------- Previous post was at 06:56 PM ----------

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

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.
[Xperia Z General] qkabierta69:
crack

Who is going to crack this issue. One way or another we need to know
[Xperia Z General] Apollo89:
It would be a great start if you could upload the C6606 firmware :)
[Xperia Z General] G1_enthusiast:
try it doesnt work...flash modem from 6603 and ZL 660x and went to a LTE location, no go.
[Xperia Z General] Apollo89:
They're taking about C6606 firmware for LTE band 4 AWS support. Those are North American LTE frequencies.
[Xperia Z General] G1_enthusiast:
I flashed a file long time ago, it was from a ZL phone, for "LTE for cannadian user" or something like that in the thread doesnt work...
[Xperia Z General] cy888:
C6606 is the t-mobile us version of the XZ. your thinking of 65xx series.
[Xperia Z General] G1_enthusiast:
I flash the modem files of the ZL i forgot the the thread but it doesnt work...
[Xperia Z General] HoOnZ:
You responded 3 times but I still don't understand what you are talking about. You flashed a ZL firmware on a C6603 phone? They're two different phones right? So the chances of them not working is understandable.
[Xperia Z General] cy888:
you keep talking about flashing from the ZL which is the 650x not the 6606.

The 6606 is the new t-mobile usa XZ version.
[Xperia Z General] mr.m27:
i think you need an LTE enabled sim to enable lte settings.....

cuz if you upgrade your connection to 4G they replace your simcard

also i'd love to get 4G in my c6602.......i only bought it cuz they claimed there will be no c6603 in our region but after 2 month they brought it < stupid Sony agent >
[Xperia Z General] G1_enthusiast:
the modem files are the same...the band are the same...flashing a rom or firmware differently not gonna make it LTE..prove me wrong.

dont know about that...i believe just swap sim and use a differnt APN
[Xperia Z General] Apollo89:
I don't think you actually read post #1? The OP explains that the C6602 probably contains all hardware to support the North American LTE band 4 (AWS).

A C6606 FTF is available now: http://xdaforums.com/showthread.php?t=2361750
[Xperia Z General] ogdobber:
If indeed the hardware is the same, the modem has to be enabled. I have a 6606 and have flashed a 6602 and a 6603 4.2.2 rom(s) both function as they should and the really only difference is a quick settings lte toggle on the 6603 rom. Lte was unaffected and functioned the same as stock as far as speeds go

I did some research on this some time ago in regards to enabling various bands (see here http://xdaforums.com/showpost.php?p=35933247&postcount=1)

*edit enabling the modem is not the same as flashing the modem
[Xperia Z General] G1_enthusiast:
yes I did and i reply with...I flashed the ZL modem files for LTE for north America and it doesnt work
[Xperia Z General] dante501:
There is a hack for it, it is called C6603.
[Xperia Z General] Apollo89:
C6603 does not support North American LTE frequencies. C6606 does.
[Xperia Z General] dante501:
Well it seems it does support some for t mobile. Supports 1 5 8 and misses 2 and 4 it supports many other lte bands but they aren't USA important. So meaning u should be able to get some lte on the C6603 better then the C6602
[Xperia Z General] Apollo89:
Please read post #1, which explains why LTE band 4 could possibly be supported by C6602. There's also the fact that C6603 is not officially for sale in North America. I'm sure that many people would be very happy if LTE band 4 support could be enabled on their C6602, which is the reason for this thread.
[Xperia Z General] dante501:
But I have a question I have the C6603 obviously. I am gonna be going back to the USA. And since it supports 3 bands out of 5 it should be able to get some lte in some areas is that correct?
[Xperia Z General] ogdobber:
Your 6603 will have no lte connectivity whatsoever in the USA
[Xperia Z General] dante501:
Even with a few working bands? That's dumb. I wish only ones America would go what the rest of the world does and not always make it so it won't work. Always those stupid extras. Annoying. Just go by the standard. Just ones. Roll eyes. Lol
[Xperia Z General] Apollo89:
There are only two GSM networks in the USA (the rest is CDMA):

- AT&T: LTE band 4 (1700/2100 MHz) and band 17 (700 MHz)

- T-Mobile: LTE band 4 (1700/2100 MHz)

The C6603 only supports LTE bands 1 (2100 MHz), 3 (1800 MHz), 5 (850 MHz), 7 (2600 MHz), 8 (900 MHz) and 20 (800 MHz), so none of the North American bands.

The problem with LTE is that they had to find free frequency space in many different parts of the world (with many different frequencies already in use). The result is a huge list of different bands worldwide: https://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
[Xperia Z General] dante501:
I know about CDMA verzion and sprint for example. But does that mean my xperia z is no useless? That's dumb. I have to sell it before coming to America then. But I was thinking there are quiet a lot of Americans that like he unlocked non branded European devices. I might be able to trade it for a t mobile branded one.
[Xperia Z General] Apollo89:
The Xperia Z does not support CDMA networks. You'll also have problems connecting to 3G in the USA:

- AT&T: UMTS/HSPA 850 MHz and 1900 MHz

- T-Mobile: UMTS/HSPA 1700/2100 MHz (AWS) and 1900 MHz

The C6603 only supports UMTS/HSPA 850 MHz, 900 MHz and 2100 MHz, so only limited 3G connectivity with AT&T and no 3G with T-Mobile.

The C6602 also supports UMTS/HSPA 1700/2100 MHz and 1900 MHz.
[Xperia Z General] dante501:
This is from the official site of Sony Germany those are the bands.

850 (Band V), 900 (Band VIII), 2100 (Band I) MHz

GSM GPRS/EDGE

850, 900, 1800, 1900 MHz

LTE

(Band 1, 3, 5, 7, 8, 20)

So pretty useless then I take it? And t mobile USA C6606 says it has those 2100 1700/2100 and 1900. So meaning mine has 2100 and also 1900. And on sony USA the C6603 has those 850 900 1700 1900 2100 1800 lte 4 so I have all besides 1700 and lte 4. So it should actually work for the most parts on 4g then.

ATT gives me those 850/1900/2100 UMTS 3G. Gsm edge 850/900/1800/1900. Lte is 4 17 also 2 5. So it seems att is fully able on giving my C6603 3g 4g. And only one lte band fits. 5. So I have to get att then or straight talk or jolt or so everything that runs on att should work.

---------- Post added at 06:34 PM ---------- Previous post was at 05:44 PM ----------

But on straight talk it says as long as it uses 850 and 1900 u keep ur t mobile 4g coverage. And it also supports all of att bands. So my C6603 should be fully working then.

---------- Post added at 06:37 PM ---------- Previous post was at 06:34 PM ----------

Sorry for unlocked international phones it says 850 and 1900 MHz bands. I have those
[Xperia Z General] Apollo89:
Okay, one last attempt.

C6603 supported frequency bands

2G (GSM/GPRS/EDGE): 850 MHz, 900 MHz, 1800 Mhz and 1900 MHz

3G (UMTS/HSPA): 850 MHz, 900 MHz and 2100 MHz

4G (LTE): bands 1, 3, 5, 7, 8 and 20

C6603 supported mobile networks in USA

AT&T 2G (GSM/GPRS/EDGE): full support (850 MHz and 1900 MHz supported)

AT&T 3G (UMTS/HSPA): partial support (850 MHz supported, 1900 MHz not supported)

AT&T 4G (LTE): no support (band 4 and 17 not supported)

T-Mobile 2G (GSM/GPRS/EDGE): full support (850 MHz and 1900 MHz)

T-Mobile 3G (UMTS/HSPA): no support (1700/2100 MHz and 1900 MHz not supported)

T-Mobile 4G (LTE): no support (band 4 not supported)

I hope it's clear to you now :)
[Xperia Z General] qkabierta69:
SO has Anyone tried the 6606 TFT

So now that the FTF for Tmobile is online has anyone tried it on the C6602 to see if it works. Im dying to know if we can enable the LTE chip.
[Xperia Z General] dante501:
So 1900 MHz isn't 1900 for both I mean gsm and UMTS?

And there again I am wondering why America has to dance out of the norm and uses different bands that are not the standard in pretty most parts in the world? Questions over questions and wondering and confused and puzzled why they always have to do it different. Annoying.

I guess flashing an either C6602 or C6606 ftf will not solve the issue I assume?
[Xperia Z General] ogdobber:
100% no. see my earlier post. the modem needs to be "enabled"...flashing the rom does not accomplish this
[Xperia Z General] atif_afzal:
Under mms...there is lte option

That means c6602 did nor support LTE....my one question when it does not support LTE then y it shows (LTE) in mms settings under bearer...its shows LTE...what does this mean

enable the modem

ho do we enable the modem then. We need some kind of method
[Xperia Z General] abajarde:
If the 06 and the 02 have the same specs then this should be doable. Someone needs to become a national here and get this done. Our 6002 deserve the speed
[Xperia Z General] Apollo89:
The most important thing to look at, is 'working bands' in your service menu under 'Service info' > 'Configuration'. When flashing C6603/C6606 firmware to C6602, you will have LTE in settings ('Network modes'), but as long as you don't have LTE working bands, it won't work.

Went from 6-7 mbs to a CONSTANT 14+mbs. Ping fluctuates and upload is slow but download is nice!
[Xperia Z General] dante501:
Does that means that everyone with an C6603 will get lte as well in the USA?
[Xperia Z General] diopskill:
Not sure I have a c6603 I can try it on also.but don't think it has the bands tho. Will report back soon
[Xperia Z General] dante501:
See that's exactly it. I ask many sources sony att t mobile and so on and everybody tells me something different tmobile and att say it should work fine on att and tmobile on there 4g network about lte they say yes and then no and I don't know I am confused now. I don't think it does work on lte. I am asking because I am in Germany currently gonna be back in the USA next month and I would hate to give the xperia z away but if lte doesn't work it does kinda sucks. But European or international phones sell good in the USA I know. I could maybe even trade it for an t mobile USA C6606?
[Xperia Z General] diopskill:
I have a c6602 and a c6603. the c6603 only works ain att hspa + and ONLY on the 850mhz band. speed.was good but no lte. but the c6602 has the lte frequency band for tmobile here. But the lte radio(if any) is not activated. all I did was change the apn settings and bam started getting lte speeds. my c6602 was new from Craig's List. The c6603 was new from London. see if you can sell it over there and just buy the c6606 when u get here.
[Xperia Z General] dante501:
Does the C6603 work on tmobile USA? Yeah i could sell in Germany but I don't get much in Germany for it anymore. Normally international phones sell pretty well in the us because no branding and unlocked. But a question. Flashing and C6606 or C6602 ftf to the C6603 wouldn't make it to work on lte then I guess? How about flashing a 6602 ftf to the 6603 would it at least get full hspa +?
[Xperia Z General] diopskill:
On Att with c6603 here in philly, i get 3-5mbs, but tmobile was only edge. (yeah i know it sux). c6602 w/att about the same. but on tmo, i get around 6-7mbs down, 3 up, but since i changed apn settings on c6602, getting 14+mbs down CONSTANTLY!!! feels nice too. c6603 does not have lte bands for the states. but c6602 has them (1700/2100).
[Xperia Z General] dante501:
So flashing an ftf Form a C6602 or C6606 won't work then for the C6603? So I would have to choose att in the states or StraightTalk. Great lol
[Xperia Z General] diopskill:
go with net10. thats what i have on c6603. straight talk att sim cards go for 100.00+!!!!!! yes !!! a 100.00
[Xperia Z General] dante501:
I have no issue with the USA but really the Americans like to make everything so it doesn't work with the rest of the world. Like the measurements you use and the mobile networks and stuff. It is a little bit annoying lol
[Xperia Z General] dante501:
What are those straight talk u buy directly from straight talk they cost 15 and then u just charge them. I already checked. And they are either att or t mobile u just have to select. And that's what straight talk says. A phone with 850 or 1900 should work. And a straight talk sim cost 14.99 plus the plan u choose.
[Xperia Z General] dante501:
Can u explain me 1 thing. Why does StraightTalk says choice international phones 850 1900 but then still only gives u a t mobile? I am confused.
[Xperia Z General] diopskill:
because straight talk does not sell att sim cards thats why. only tmobile

---------- Post added at 10:59 PM ---------- Previous post was at 10:57 PM ----------

yes that what it says BUT they only give out tmobile. i have tried and even they will tell you on the phone.
[Xperia Z General] dante501:
Ah so net 10 directly att great.
[Xperia Z General] diopskill:
yep. they also have tmobile too. but my only gripe with them is they only give you 1.5gb of data and then they cut you off. yes it has happen to me. but that is only with att. if you get the tmobile sim from net10 it is unlimited. but again only edge speeds on c6603. if you use wifi alot then 1.5gb is good and it is fast. i use alot of data. thats why i went and got a c6602. it is pentaband like nexus 4. and i agree with you on American phones, have not bought usa phone in 4years.
[Xperia Z General] dante501:
I hate this being branded simlock crap. Something like that is only on iPhone here. But if u actually buy in a store from apple it isn't sim locked. But the iphone is the only phone on carriers that's sim locked. Typically American foolishness lol. OK **** I have to sell the xperia z and i just the original sony charging dock. This sucks.
[Xperia Z General] diopskill:
you should get at least 500..
[Xperia Z General] dante501:
U mean in the USA in Germany no way. And u talking us dollars right? I am lucky to get 300 in Germany what cones to roughly 400 us dollars.

---------- Post added at 04:35 PM ---------- Previous post was at 04:34 PM ----------

But on att it works for the biggest part right?
[Xperia Z General] dante501:
OK then I keep it. I was thinking it was just limited hspa+ connectivity. Then I honestly don't see the point to have the C6602 since it official doesn't support lte. Either Europe nor USA official and when u get with the C6603 hspa + everywhere then there is actually no need for the C6602 or does the C6602 also gets it on T Mobile USA? I am on the original T mobile from Germany by the way. I would prefer t mobile in the USA again nut looks like I have to go with someone else. Thanks for ur help. I appreciate it.
[Xperia Z General] diopskill:
yes the c6602 gets ALL hspa+ on both tmo and att. since c6603 does not support lte here in states, c6602 is the better option. no prob and good luck!:good:
[Xperia Z General] dante501:
Is there any other options I can choose besides att that use the same network bands? U told me net 10. Then there is jolt. But I heard they suck pretty bad. So is there anything else?
[Xperia Z General] diopskill:
net10 is about the best
[Xperia Z General] dante501:
Ok thanks. Appreciate it.
[Xperia Z General] carlsbad28:
I'm extremely bummed out that the 6602 doesn't support LTE. To think that 6603 has exactly the same specs.... I hope the modem could be activated soon.
[Xperia Z General] paperWastage:
sorry for the long hiatus... don't own a xperia device, so no reason to drop in

next steps if you want to know

1) do/find a proper teardown of the C6602.

my first post, remember how I said I could only find the power amplifier for 1700mhz, but not 2100mhz? Find a chip on C6602 that does 2100mhz. otherwise, you only get LTE for uploading, and HSDPA for downloading

2) dump more data.

From looking at the nexus 4 LTE hack, you'll need to find a baseband that allows LTE (probably from C6603)

Then you might need to do some build.prop hacks, some phone dialer secret menu hacks,...

http://hippowise.com/how-to-permanently-enable-lte-on-android-4-2-2-nexus-4/

hmm... hsdpa max is 14.4mbps... could be hspa+? don't know enough details about hspa+ and backward compatibility with hsdpa phones, need to do more research
[Xperia Z General] ahassouna:
HSPA+ max speed is 42Mb/s till 56 Mb/s and LTE most probably starts after 56Mb/s
