Hi, I have an XDA, and since I have to travel a lot, I'm looking for a tool to
make the XDA a Triband PDA. right now I have 900/1900 Mhz and need to switch also to 1800 MHz. I read about a Bandswitch tool, but can not find it anywhere.
Who can help ???
The bandswitch tool will not enhance the phone hardware, your phone is 900/1900, it is a dual band phone, not tri-band.
you can download it here: http://wiki.xda-developers.com/wiki/BandSwitchTool

Not a problem...but interesting. I just noticed that the model number on my T-Mobile reports it as a PW10A1 instead of PW1OB1. So a question:
Does it show this number by first querying the hardware or is this info stored somewhere in the ROM?
Cheers.
It is stored in the ROM. The A or B refers to different modem part (to do 1800 or 1900), and the 1 or 2 that follows it refers to slightly different plastic housing.
This is interesting. the first error message I received when trying to do SE Rom update was that my device was PW10B1, while the upgrade was trying to make my unit PW10A1. Mine is a USA XDA.
This eventually (and mysteriously) worked itself out.
However in light of your reply XDA developer, can you tell me if this unit operates as a triband unit? I ran bandswitch and 1800 came up as an allowable choice.
Also, do I need to change bands if I travel overseas or is this automatic?
Users of the PW10B model (even though it thinks it's called PW10A after the Special Edition ROM upgrade) must switch manually between 900 and 1900. Users of PW10A can leave it at 900/1800 and switch automatically.
Functionality of 900/1800 phones (PW10A) in the 1900 band has been reported, but is believed to be erratic at best.
Thanks XDA
If users of the PW10B model have to switch from 900 to 1900 manually,
if we also manually switch to the 900/1800 setting, will we get functionality on an 1800 mhz network? (such as some of Asia)

Maybe. Possibly only some of the time, if you're lucky, and very likely with lousy coverage, since your filters are tuned for 1900 MHz.

Peter, I unlocked my TMO XDA 1 to sell it using XDA-Developers-V21 (had to use NK.nb1 & SD card bootloader method). I'm trying to put my previous version back on and it thinks the phone is PW10A and won't do the upgrade. You mentioned PW10B users must manually switch between 900 and 1900. How do I set my phone identity back to Model #PW10B so I can put my previous ROM4.01.00 on?

You need to do it the other way around: adapt the ROM image so that Programme A thinks it is right for your phone. For this you need our tool adaptROM.
I would like to know how many differences there are between this two kind of dual band.
i've bought a T-mobile from USA (i'm still waiting for it so i don't have it now) and i saw that it is a 900/1900. I'm in italy, so i would like to know if i'll use only 900 or 1900 too (i think in italy 1800 is used).
i think i'll have to unlock it, the vendor told me it is a pocket pc 2003, do XDAunlock, work on it?
(i'm sorry for the last off topic question...i post here to not make too many post around the forum)

I'm sorry to tell you since your network works on 1800 Mhz your new T-mobile PW10B1 wont work on this frequency it's made for 900/1900 Mhz if you unlocked it or not it's not gona work, you need the PW10A1 devices they work on 900/1800 Mhz.
but there are cellphone companies in eu who use 900 maybe there are some in your country
if not well thats too bad
oh....no..... :shock:
is there anithing i can do? radio update??? something like this!
Your special edition ROM can help me?
from what i've been able to understand about the 900/1900 then it's a hardware limit the GSM part of the xda1 will have to be physically removed which would most likely be way more expensive then getting a new device
of cause i could be wrong
The XDA1 is available in two flavours (from what I read):
USA: 900/1900 bands
EU: 900/1800 bands
Since both flavours support the 900 band, you should be able to use it in Europ on one of the 'old' networks.
In Holland both KPN and Vodafone have nationwide coverage on 900MHz.
Since TIM is and 'old' company too (Telecom Italia isnt it?) I guess theyre on 900 too. To be sure: check the websites of the Italian mobile operators. Be aware that reception in some areas might be less than if you could use both 900 and 1800 bands as more and more operators are extending their networks on 1800 only (because of lack of free 900 band frequencies). I noticed this a few years back in France where in rural areas there was no coverage with a 900 phone and full reception with a 900/1800 phone (same network).
Reading the forum i've read that is possible to chose band 900/1800 and 900/1900 by bootloader and pressing calendar...can this be true for some model?
p.s. Of course TIM uses 900...i wonder if it will ever use 1900 one day
i think UTMS or some other replacement will take over before us and eu start to use the std's of eachother
just another question, i found information about special edition rom. It says that with bandswitch.exe some devices may work with other "not natural" band. So i'll try when my XDA will be shipped.
TIM wil NEVER use 1900, at least not in Europe. The 1900 band is not available for telecoms in Europe (just like the 1800 band is not available in USA)
I've got T-Mobile from US working in Russia on 800/1800 through ROM upgrade. What it did - it removed SIM Lock and turned the device into 3-band. Works perfect.

i haver never heard about anybody being able to make a dualband into a triband using just software the filters and mixers in the hardware part og the gsm are different
I have never heard about that either. As far as I know frequencies are hardware based. Otherwise we could flash our XDA's to anything we wanted.
I have researched this for weeks and weeks since I need my XDA I to work on the 850Mhz network in the US quite badly.
Please post exactly how you did it
1800/1900
I got the same problem you do but reverse , I'm in the U.S and bought the phone from Europe ( qtek 1010 ) my phone will not work in the U.S because the network here is 1900 and in europe 1800. If you want I can trade with you if you have the same phone. I got all the package in a box.

There are 3 major networks in Italy that have 900 mhz networks.
They are:
Telecom Italia Mobile (TIM)
GSM 900/1800
Vodafone Omnitel N.V.
GSM 900/1800
Wind Telecomunicazioni SpA
GSM 900/1800
If you are within any of their networks you should have service with your
current Wallaby. (XDAI). You should be able to insert your sim card and go.
Some ROMS auto select the available network, others do not. There is also a program that you can cook into a ROM that give you a software selctable band switch.
I hope this helps?
Joe
Just to clarify my last post:
It has been discussed on this forum, for a few years, that you cannot
change a 900/1900 phone to 900/1800 using software.
However since your phone does operate on 900 mhz and there are
900 mhz throughout Italy, including Sardinia, you should have no problem using your current phone. In fact I have used my USA 900/1900) XDAI in Italy.
Let us know how you make out.

900/1900 T-Mobile -- Swap for an 900/1800 XDA ?
Straight swap...I made a mistake and bought a T-Mobile from the US thinking it would work in NZ....it won't and everyone on the forums agrees....so only option is to replace with a European one...
If anyone is interested, post a reply and we can set something up.
Cheers, Hamish
BandSwitching
I live in Jamaica, we have to GSM networks, 850/1900 & 900/1800 my XDA1 works well on both networks... although signal strength from the 900/1800 is stronger it makes no big difference... I believe the shorter band is essential in buildings etc. so wait till you get the phone and give it a try.
I tried the Band Switching application in the Special Edition ROM, it made no real difference.
Slightly off topic can someone point me to an explanation of UMTS???
Apologize if this is a stupid question ...
But it it possible to get niki to do 3g on a freq other than 2100 ?
that would require a major hardware change, so its unlikely.
thank you. that helps.
On 2-14-08, HTC started selling the HTC Touch Dual 850 in Australia. The big question is whether it has the same chips inside as the Touch Dual. There has been some talk that the regular Touch Dual has a chip that works on the 850 frequency, so I'd say there is a good chance the two devices are the same with differnt ROMs.
We really need someone to upload the ROM from a Touch Dual 850.
I believe that there were two differing Qualcomm 7200 chipsets produced:
One with support for 850/900/1800/1900 MHz (the US version, in which the 850 & 1900 MHz band is used for UMTS). And one which supports 900/1800/1900/2100 MHz (for Europe) In which the 2100 MHz band is used for HSDPA.
You could be right though, it may be that the only differences are in software.
The device can't support all five frequencies(at least it shouldn't be able to ), but it may be possible to pick and choose by flashing radio roms.
Only time will tell...
I have read the lg ks20 manuel ... if you need more frequency, you need hardware parts! on of this parts are a RF switcher. the radio read out the nv ram too.
I'd say that just about does it. I will be wanting an 850 model soon.
in the moment ... i think ... no 850mhz nike!!!
hoping a radio update can do it for the niki since i just bought one in the us and just learnt about this issue.
do you think the australia rom would fix it or the radio, i do know the australia rom is available for download but isn't the radio more important for this issue?

Has anyone found out any new info about this? I too have issues with the Niki100 not covering all the bands I need for coverage in my area and have no 3G. With the US Touch Dual coming out soon, or with the Australia release, I was hoping someone had a radio flash that could provie if upgrading the radio fimrware worked.
you havent understand what i have tell!!!
niki havent the right RV Switch!!! You cant change anything to handle G3 network on 850MHz or 1900MHz!!!
the US Touch Dual or AUS Touch Dual isnt a HTC Niki ... it is a HTC NEON!!!
Both can use the same OS and Radio Roms! The Radio Rom is every time the same!
@NetrunnerAT
just to be fare:
there are 2 models of HTC Touch Dual available here in Australia:
HTC Touch Dual UMTS 2100MHz
HTC Touch Dual UMTS 850MHz (Telstra NextG frequencies)
ok again ... Touch Dual 850MHz is a HTC NEON!!!! Both Device have the same Case and a simulare Chipset, but different RV Chips!!!
Don't bug me!
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

like
"ItemName2"="UMTS(900+2100)+GSM(900+1800)"

,
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]

Will the real archos 3g stick work in my 80g9 in canada? It looks as if, if I just install my microsim from another device, it should work...am I missing something?
If it is bought in Europe - probably not. There are different GSM and UMTS bands used in Europe, NA or Asia Pacific. Generally speaking, there are five of them: 850, 900, 1800, 1900 and 2100 MHz. А particular modem chip may support them all, or, say, only 3 of them. A particular firmware version may also play role. If your particular mobile provider uses a different band, this modem won't work with his SIM card. Or, say, work in only 2G or only 3G mode, whichever service is in the compatible band.
First of all, see whether the stick is live at all; try connecting it to a regular PC and see if it is detected in the system, drivers are picked up, and you can access it with some console utility. Second, see if it can connect to the mobile network. If and only of it works OK, then try using it at the tablet.
