Pardon me for asking but this has bugged me for a while:
I doubt if the Raphael is really produced in two hardware versions: one that supports UMTS 900/2100 MHz in Europe and another that supports UMTS 1900/850 MHz in the US?
Do any of the European friends here flash the Radio ROM v1.14.25.35 (extracted from AT&T ROM in the US) to their European version of the Raphael and with a tweak in the registry key
HKLM\Software\OEM\PhoneSetting\BandType
Click to expand...
Click to collapse
like
"ItemName2"="UMTS(900+2100)+GSM(900+1800)"
Click to expand...

,
i.e., to make the UMTS 900 MHz band known to the machine, are able to connect to their 900 MHz 3G network properly?
Apparently, the 900 MHz UMTS band was not included in the default BandType after the American AT&T Radio ROM is flashed.
This is actually a very good & important question & point. Particullarly with the newer devices that are comiing out. In an effort to streamline production, HTC has changed somewhat the way the restrict devices from operating on different bands. Now you find that even CDMA & GSM device are able or would be able to operate, strictly speaking of hardware, on one or the other network except for the firmware. According to FCC documents, HTC is locking devices to networks via the firmware. This may make it possible to opperate any device on any network give that there is a place to insert the sim card.
I am using the new radio, & I have been able to use it on both the US & EU gsm frequencies. You can selct the band you want, but you need to use the band switch program as the EU band has been disabled via the registry, but it still exists within the radio firmware.

Thanks, gsleon3 for your input. I have this doubt because many people on this boards mention cross-flashing and the issues with two different hardware versions; whereas, according to Section 1.1 on "Product Features" of the Raphael Service Manual, the hardware itself supports HSPA/UMTS on 5 bands, i.e., 850, 900, 1700, 1900 and 2100 MHz and GSM/GPRS/EDGE on 4 bands, i.e., 850, 900, 1800 and 1900 MHz. Raphaels are produced in different SKUs with some bands selectively enabled, though.
I'm in Germany w/ a German O2 XDA and I've flashed the new radios with no problems. I haven't flashed to .25.35 yet, but probably will tonight.
[EDIT] Just installed .25.35, and it works 100%. We'll see about battery life tomorrow... [/EDIT]

What are the differences between the X10i and X10a? I know the Canadian version (x10a) has a different radio then the X10i (Europe).
This is the Only Differences I could find.
X10I......... GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS1700, UMTS2100 .................... HSDPA 7.2 Mbit
X10A........ GSM850, GSM900, GSM1800, GSM1900, UMTS800, UMTS850, UMTS1900, UMTS2100 ...... HSDPA 10.2 Mbit
Is there else anything that might be different??
As far as i know, no.
Only the 3G frequency which is different in north america (well, only for some carriers).
Rogers, afaik is using 850 so you need X10a otherway no 3G
i think the HSDPA speeds are the same for both, the only difference is one of the 3G bands
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
HSDPA 850 / 1900 / 2100 - X10a for Americas
Is there a way to convert between the X10i and the X10a?
Please advise if there is a tutorial link or something.
Thank you for your help.
Regards L
You can't do that.. maybe if you change the Chip..
X10a has 800/850/1900/2100 WCDMA and quad band GSM/EDGE
X10i has 900/1700/2100 WCDMA and quad band GSM/EDGE
'a' uses QSD8650 processor 'i' uses QSD8250
800 WCDMA band if anyone wonders is for DoCoMo in Japan.
Hello. How can I identify which one I have?
Thanks!

X10 in Canada
In this case, for the Canadian market, I believe the X10i is compatible with Wind Mobile (1700), while X10a is with Rogers/Fido/Chatr. Am I wrong?
you are correct, for HSPA rogers, bell, and telus are all on the 850 and use x10a
wind mobile has the same frequency as t-mobile USA so x10i would work. however wind mobile is only available in select very few markets
I have a X10i and can receive 3G on Rogers in Canada. On the side of my box it says UMTS/HSPA Band 1/2/5/6 (Along with the quad band GSM), can someone explain to me what the numbers mean?
odd ...
That's odd because I have a x10i and it says UMTS/HSPA 1/4/8
I also don't know what these numbers mean so basically have the same question.
Where did you get yours from? And are you sure it is a X10i and are you sure you have 3G? Does the data connection icon say "G" or "3G"? I'm asking because based on previous discussion, x10i is not supposed to work on Rogers so I'm very surprised.
Right underneath the bands mine says SV, DA, FI, NO which I believe stands for Sweden, Denmark, Finland, Norway as their localization codes.
It says 3G beside the signal bar, and here are picts of my service menu:
The service menu says I have an X10i
Here are the bands it supports, the service menu has the same band numbers as on my box:
Bought the phone used for the wife. So can anyone explain the band numbers?, as I am not familiar with SE phones, I have always used HTC
According to the UMTS bands table from wikipedia, those numbers mean 2100, 1900, 850, 800
I can't post the link because I'm a new user and the system doesn't allow me to post the links but if you wikipedia umts you'll find it.
I didn't know different x10i's could support different bands. I wonder if this means a different hardware as well or just a software change. Anyone?
I maybe wrong but I did read of people changing the firmware from the 10a to the 10i this will NOT change the radios.. simple way to check is to look under the battery label as the software can be changed.

I used to have an Xperia X1a, and everytime i did flash a rom, my phone was always a x1i, but was fully functional, what i need to do was copy a simple modelname.txt file to the windows folder with x1a in it, and the phone became a x1a, i think that the model we get on the about screen is from some file on the rom, but what really defines the model is the hardware, not the sticker from behind.
my 2 cents

Thanks for the info! So does this mean that I really have an X10a that had been flashed? Sorry for the newbie questions, but this is the first time for me playing with an Andriod device. In my phone settings "About phone" is says:
Model Number - X10i
Firmware Version - 1.6 (I assume this is the Andriod version)
Baseband Version - 1.0.10
Kernal Version - 2.6.29-rel
Build Number - R1FA010
Is the build number the Andriod release number? ie. like windows mobile, there is wm6 with build 23xxx?
(I have never flashed the phone since I got it)
for changing from x10i to x10a and vice versa but there r a problem Flashing your Xperia X10i to X10a (and vice versa) will result in SEUS not being able to update your phone for future updates
sry am a new user so send me an email and i'll send u the link

I seem to have a slightly odd problem, in areas where O2 is now providing 900 MHz 3G in addition to the older 2100 MHz my 3G data pretty much stops working unless I change settings in the service menu to only use 900 MHz 3G in which case it works fine. The problem then is anywhere that 900 MHz 3G is unavailable I obviously lose 3G service unless I re-enable 2100 MHz in the service menu.
If only 2100 MHz 3G is available and I set it back to default then data works without any problems, but returning to an area offering both causes data to stop working within minutes. It would appear that it always uses the 2100 MHz band when both are available if that makes any difference.
I have tried several different modems to no avail, and returning the phone to latest stock firmware for the UK. Doing the latter seemed to help, until I rooted the phone using Doomlords script at which point it stared playing up again. That might just be coincidental, I really don't know.
From searching around various places I couldn't find anyone experiencing similar issues, unless my search skills are failing badly. I guess it leaves me with two questions, firstly any ideas on why this is occurring?
And secondly is it possible to set an order of preference for 3G bands anywhere, as I couldn't find anything in the service menus to do that. Based on how the phone is behaving I'd imagine if it used the 900 MHz band as a preference where available the problem might go away.
Hello everyone,
"The LTE standard can be used with many different frequency bands. In North America, 700 and 1700 MHz are planned to be used; 800, 1800, 2600 MHz in Europe; 1800 and 2600 MHz in Asia; and 1800 MHz in Australia. As a result, phones from one country may not work in other countries. Users will need a multi-band capable phone for roaming internationally." (en.wikipedia.org)
So far, I have not heard of any LTE cell phone able to adapt to this multi-frequency international situation.
Even within the USA, it does not seem possible for an unlocked LTE cell phone which has been bought through one carrier to be used with another one.
Well, it should be possible !
After all, LTE is an international standard supporting all frequency bands, flexible bandwidth and both FDD and TDD duplexes ...
So it might not be that difficult to make these phones be able to use different LTE frequencies.
All radio systems can easily scan the whole spectrum in order to settle on the next available or desired channel. Another example, on Android Gingerbread phones :
"Settings-->Wireless & Networks-->Mobile Networks-->Network Operators--> Search Network" shows you all the mobile carriers available in your area, offering you the possibility to manually register on a specific network.
All this means that it should be technically possible to buy an unlocked LTE cell phone in the US for example, buy a sim card in another country where the LTE frequency is different, and everything should work fine, maybe with some software tweak.
Has anybody tried this already ?
Hello,
I can not get LTE working with my black Lumia 920.
The phone is supposedly RM-821 global version with pentaband LTE support disabled in firmware. Bought in Vietnam from official retailer and I am using it here in Finland where I live (LTE frequencies 1800 and 2600 are used by my operator). There is no 4G option in settings->mobile network->highest connection speed. I can go to field test menu (##3282+call) -> settings and select 4G only there but as soon as I leave that menu the setting reverts back to whatever it was set before. Also no LTE network is found during the time I stay in the menu.
This issue is driving me nuts.
Here is what I have tried so far with no success resolving the issue:
- Flashing in 8-10 different firmwares/softwares (several different region rm-821 models including finnish) with Nokia care suite.
- Called my operator several times and requested and got a new sim card to rule out the possibility that the problem lies there.
- Called nokia customer care twice and they keep telling me that the phone - for being the global variant - has LTE support on hardware level but it is just disabled in software.
- Checked the APN settings. If I select the access point with access point name for 4G network with my operator I don´t get connected at all. It says 3G in the topbar but network simply doesn´t work.
- Done this all in area where there should be 99,9% certainty for LTE-network availability.
So if anyone can point out something that I have missed or could still try please do. Would be highly appreciated!
You say it has octaband support. Have you confirmed what frequencies it operates at? It is possible that even being octaband versus pentaband that your frequency is not in that phones range. Is there any documentation that says what bands your model supports?

Sorry I mean pentaband ofcourse. It is supposed to support the 800, 900, 1800, 2100 and 2600mhz frequencies.

Now that is out of the way, are you sure that your provider has LTE coverage in your exact area? Not just over all but at your exact location? Also is the signal you get at your location normally strong. If it is not strong enough the phone will drop to a lower band to conserve bandwidth.
you may find that nokia has not enabled it yet, they my do so at a later date by firmware .. the CVBG also do not have 4g working out of the box
I am having the same problem.. I bought a 920 when on holiday in Thailand.. now back home and it will not show 4G.. only 3G... whereas my 820 gets 4G fine...
Its an rm-821... and like the original poster i tried flashing a known 4G firmware onto the phone..
Do they actually manufacture 920s that are not 4G ?? I just assumed they were all 4G.... I guess i was wrong..
Have you try this app and manually set for the LTE? just a suggestion
http://forum.xda-developers.com/showthread.php?t=2082683&highlight=exclusive+for+nokia
Flash your RM-821 with the Finnish firmware 059Q917 (1308.1) . It will activate the LTE as it did mine.

Just a question, when a new update comes out in the future, what product code shall be used? The firmware's or hardware's?

Updates which are firmware, look at the hardware in the phone to confirm product and region compatibility.
