Is XDA a triband device? - MDA, XDA, 1010 General

' .... We still haven't tested whether the device is actually a tri-band phone that is just software-limited to being a dual-band phone, but postings on the net seem to indicate that it is not actually a tri-band phone. But even though we think we know, we still need someone with access to a European phone in USA...'
is it already tested???

Not sure. But it isn't. We're pretty sure of that: radio parts are different.
And don't try to flash a 900/1800 modem with 900/1900 firmware either: you'll ruin it.

Not tri band
There are two different devices.
PW10A1 is 900/1800MHz
PW10B1 is 900/1900MHz FCC ID: NM8SN
Only the PW10B1 is approved for use in the USA. The RF components are different, even though the Bootloader is common between both devices.

In other words, you will ruin it if you flash it with a different GSM version, but it is possible to flash it back using bootloader, right?

No, the bootloader method of flashing currently only covers the WinCE (main) ROM, not the GSM ROM. There is a way, but we simply know too little at this time... Progress is being made though...

I now have a confirmed report of the XDA not being a tri-band device. A friend of my took an European XDA to the US yesterday. Like we expected the device is not working there. Even not when switched to "GSM1900".
This confirms the idea of an universal bootloader and different GSM stacks. The European/Asian XDA is simple not working on GSM1900 networks. If you travel a lot, it's better to buy a T-Mobile or AT&T device as those devices work on GSM900 and GSM1900...

It's really much better not to speak of bootloader in connection with the modem part. The bootloader resides in the first 256 kilobytes of the main ROM. The rest of this ROM (32 MB - 256 kB) is taken up by the operating system, with a little room to spare for contacts and other things which are explicitly saved to flash by the user. The OS ROM can be flashed using the RUU program (also called Programme A by HTC), but it can also be flashed using the bootloader, residing in the same ROM.
The modem is a different contraption alltogether. It has its own processor, RAM (256 kB) and ROM (4 MB), and is possibly only wired to the main processor with a serial port (operating at 115 kbps). The modem holds the software loaded in using the Radio Stack Upgrade (also called Programme B by HTC). The 900/1800 and the 900/1900 modems have both different software and different hardware. Flashing software of one into the other makes it not work anymore, and we're not sure whether there's always a way back.
We're learning more and more about the modem upgrade process. But we still advise against playing around with the modem. Upgrade if you have to (maybe skipping 4.14 and wait for higher versions if you haven't upgraded yet), but if you're not deeply technically inclined then don't **** with it beyond that unless you wanna risk losing it.

Can't get a signal on my SX56-- Help

I bought a new SX56 from an ebayer and it appears to be unlocked etc. I put my current active Cingular SIM card in it but I get a no signal message after it searches for signal. The device came with xda-developers.com ROM version v1.2 on it. I have tried to switch to all of the different Bandswitch settings with no success. HELP PLEASE!!! ANYONE??!!
What's your RSU version ... you can get it from device info or displayed while booting.
PS: it's very risky to use the GSM menu this way. Check with your operator and select the right band once and for ever.
No signal on SX56
My device info is:
ROM ver: 3.17.03 ENG
ROM date? 05/15/03
Radio Version 6.12
Protocol version 324e4
Seems you have a bit old ROM and RSU ... you better check with one in your area but I see here some people have either TMO 4.01.00 + 6.24 or AT&T 30.09 + A30 and they are on Cingular. The right bandwidth setting is the key factor.
Thanks for your reply. I don't know how to do the updates you refer to. I hate to return the thing because I got a good deal on it, but if I can't use it on Cingular I don't know what else to do with it? Any help would be appreciated.
Doc
You can get the complete TMO update (ROM + RSU) here ftp://tmobile:[email protected]:21
Good luck ...
Hi,
I tried to link and get an error trying to connect. Could you please send it again :?: ? Do you think updating to windows 2003 would be if help? I can download it for free from the Siemens website. I just don't want it to lock the phone or cause any damage!
Doc
The official update from AT&T should be OK ... however, you device is better to be PW10B type (check the rear sticker) these upgrades were made for USA use.
Also, if you are in the Cingular 850Mhz only zone, you wont be able to catch signal, cause none of the RSU's will support this band.... (quite unfortunate for all of us in North America)
Thanks for your reply. I'm not sure of the Band mHz on Cingular. I will try to find out from them if I can. Guess I'm the die hard type but I still want it to work or I'll have to abandon it. Any other help will be appreciated

Quite unfortunate indeed. What are the chances that AT&T will release one in the future to make it compatible with Cingular 850 networks after the merger?
I still think there is a way to tune a digital device to another frequency. AT&T has a deal on these for $99.99 and it was just bought out by Cingular. It would be logical that Siemens has something in the mix an upgraded model, different freq. etc.

That's what I am thinking. I am a Cingular employee so I bought one to put on my ERP but I can only use AT&T and T-Mobile signals at the moment.
I am 100% certain that it is possible to get the device to work on 850, more than likely just restricted in the radio stack.
You are lucky!! I have six phones through Cingular and they have been trying to get me a Treo 600 since December!! I'd prefer a windows based device hence my reason for buying a SX56. I had no way to know it would not work on Cingular. All the ads I see for unlocked phones claim they will work on any GSM carrier with an active SIM card.
Obviously it doesn't work hence my involvement in all of this!!
Doc
It is possible that somebody has got cingular sim to work on 850, if they were in close proximity to a mast maybe the 50mhz wouldnt mean too much and a signal could be acquired, but you would still be using a phone detuned by 50mhz which isnt an ideal situation.
I'm not an expert but 50mhz is a pretty big difference in frequency. The splash over from 800 to 850 or 900 to 850 is pretty big. It probably would not work very well even a few feet away from the site where it functions. Still there has to be a way to to tune one of these to 850mhz.
Doc
re: the 850 tunning question, As far as I understand this is a hardware aspect of the radio, thus you can not tune to this freq. This is also the reason AT&T did not brand the XDA II, because HTC would not impliment 850 into the device. You are more likely to see a HP6300 or MPx in this department as they are both quadband phones (meaning 850 implimentation) the real question is, will either of these phones be EDGE enabled? My quess is the HP will but the MPx will not. Reasoning: Rumor was HP was using TI Ref design WANDA. TI make EDGE hardware for phones. TI processor may be in the HP phone. The bottom line is you will need new hardware for 850 or EDGE. Sorry for the bad news, I too would love to be proved wrong. Guess I'll have to pony the dough for one of these two new devices. I really loved my HTC device but if they aren't going to keep up...I have no choice. I still feel the XDA will be a better over all device, but without 850 & EDGE implimentation it's going to fall way short. It's nice to own a Corvet, but if a Honda goes faster...why buy the brand name.

I'm getting depressed. I bought this thing thinking it would just be a matter of sticking the SIM card in and off we go!! I've emailed 15 times, joined three different PDA/Phone forums and learned more about these damn things than I ever intended. Now I have a slow PDA, a car charger, extra case, extra sync/usb cable and it won't work on Cingular which I can't change!!!

Australian Network Original ROMS - Updated 3 Jan 09

Hi to all budding cooks!
I have links here - thanks to HTC e-Club Australia - for those who wish to download the original signed ROMS for three of the four Australian mobile network providers: Optus, Vodafone and 3 Mobile. Unfortunately the folks at HTC haven't seen fit to publicly release a Telstra-specific ROM for the Next-G network, or else I'd have a link here for that too.
The ROMs available from the links below include the radio in the package, and will install it along with the network-specific stuff for each provider.
Click on the link to start your direct-to-PC download:
Hutchison Telecoms - 3 Mobile (this is the latest one, released on December 4, 2008)
Optus and Vodafone Networks (this is the same one HTC released on October 27, 2008 - no other update for Optus/Vodafone available as of January 3, 2009)
Links also added to the Raphael Wiki Page
Hope these can be of help to someone.....
Thanks for these. Have you tested any of them
Optus / Vodafone ROM
OK I have flash to this rom and so far so good.
It's a fully unbranded rom. Not even the program shortcuts in touchflow have been inserted.
This upgrade has fixed a main problem of mms for me where I can now send and receive mms again. I could not do this with.405 WWE rom. Radio is the the stock radio and I have had not improvment here in AUS and will upgrade to .28 or .32 shortly.
No speed diffrence and you will need to redo your confiqs again or restore from backup

Only the 3 Mobile and Optus ones, and both work well. Haven't tried the Telstra ones, 'cos I hate Telstra and everything they stand for. My only dislikes are the telco's brandings everywhere on the 3 Mobile ROM, other than that they run exactly like the stock HTC ROM.
As for the radio I'm using with Optus, it's 1.02.25.32, and here in Newcastle it's clear as crystal. Send/receive MMS is fine, and SMS goes on GSM like it always has with Optus.

Great thanks. Yes I am using the Optus one as well and still on orignal radio and so far so good, only had issue restoring the backups would not reinstall the programs and settings which is a bit of a pain But the Rom feels faster after the settings applied then the orignal I had. I don't know why I could not get mms to work on orignal rom .405 I had all the correct settings and it would never send now it's like perfect again.
Will upgrade radio next as .19 always has some lagg in connecting to the network

Not sure, mate. Seeming though I live in Australia, I haven't been able to set up my computer somewhere in the UK and get my hands on a Vodafone UK edition Raph to test it. Maybe you could test it yourself, see how it goes, and post your results here.
There's nothing to worry about. Only one of four things could happen, and all of them are reversible.
(1) The flash is a failure: you brick the phone. Elsewhere in this forum are threads committed to helping those with bricked phones;
(2) The flash is a success, but you don't like the look, feel and speed of the ROM post-install;
(3) The flash is a success, but the Radio/modem isn't working well for you on your particular network, or
(4) The flash is a success and the whole thing works to your satisfaction.
Trial and error is the key to advancement. You will get nowhere if you don't try, and you always have here a number of others with the same device, to help you out of a bind if you get stuck. Great minds think alike, and as Dr. Conrad Zimsky said in 'The Core', "That's all science is, is best guess..."
cheers mate, my only worry is bricking. im new to winmo so all the flashin is new to me.

I suggest first and foremost you go to the Raphael Elite Team Thread and grab the HardSPL from there. For further instructions on how not to brick your phone, check out this thread. If you haven't already, install ActiveSync 4.5 for Windows XP, or Mobile Device Center 6.1 for Vista. Make sure you download and install the correct version for your operating system, as there are 32- and 64-bit variants.
Connect your phone to your PC through whatever Sync application you installed, then Flash your phone with the HardSPL first. Trust me, I've done it myself and it works, as long as you follow the instructions the boys have left in a text file included in the *.zip's you'll grab from that thread. After that, it's all smooth sailing. Installation of ROM's from wherever you decide to grab them is a risk each time you do it, but make sure that if the ROM's chef has specified a certain Radio to use with what he's cooked, that you Flash that to your device first then hard-reset, then Flash the ROM.
Hope this has helped a little bit.....

Try going back to the original SPL that you can grab from the same place you got the unsigned from. Then try flashing with the Vodafone/Optus one I've posted links to @top of thread.
same error. everything back to stock & nothings bricked so no biggy. i wanted the radios more than anything because i get pretty sucky reception at home but vodafone say i shudnt. oh well, no harm done a least.
Thanks for your help.

As far as I am aware, the device flicks between whatever frequency is available. That is, if the 900MHz band is there, then it uses it, but when the 2100MHz band is around, it'll switch to that one. I was happy with that stock Optus ROM in my Raph, using my Optus SIM card, but have gone back to the T.I.R. (PDM) one simply 'cos I like it.
My Raph is an original outright device bought from 3 Mobile - with the 3 generic ROM installed - but because I jumped from a stock Vodafone service to Optus ('cos Vodafone here in Newcastle are not providing 3G/HSDPA) I chose a ROM I liked the look of.

Hi, this is an interesting discussion about band freq's here...
I'm running 1.02.25.19 with ROMeOS 1.21 WWE and I see the following options:
Auto
GSM(900+1800)+UMTS(2100)
GSM(1900+850)+UMTS(1900+850)
UMTS(2100+800)
I'm with Vodafone. I do not experience any call quality issues, slow call connection or internet speed issues... so I'm not too sure if this changes anything considering Vodafone mainly uses 1800 and they're still in the process of running out 900MHz.
FWIW... I tried running Radio 1.02.25.28 but I did experience issues with my camera, which is why I'm back on .19

[Q] Activate GSM/WCDMA Radios

Both versions have a GSM/WCDMA/HSPA chipset, but GSM capability has been disabled in the Verizon phone. Interestingly, the RAZR uses the Qualcomm MDM6600...which is capable of all the aforementioned networks.
As for activating the GSM radio in the Verizon version... my guess is that it will require a custom kernel of some sort...

The MDM6600 is actually a modem, and not a SoC if that's what you were thinking. It's used on all of Verizon's current global phones, including the iPhone.
From the FCC on the Bionic:
The WCDMA/GSM network functions have been disabled by the firmware and are SIM locked by all US operators on this product.

And Anandtech:
...This power amp is actually quad band 850/900/1800/1900 MHz. In its shipping form, the Bionic is limited to just 850/1900 for CDMA2000 in the USA, however, I have very little doubt this device could also be used with WCDMA on all four bands with some tweaking. FCC documents also talk about WCDMA functionality being disabled...

I was thinking along the same lines.
I have a Photon and the GSM bands are locked from being used on other US carriers. There have beem discussions that the radio files are what need to be changed/hacked. I wonder if the premise would be the same as I'd love to make this a global phone...

Hmmm... there doesn't seem to be much interest in this.
Modifying AMSS is really dangerous and I don't think it will be possible even after a bootloader unlock as radio is protected with another "lock code". It should be unlocked only on Engineering devices.
Would it be possible to load the radios of the GSM version onto it?

If there is one thing that Moto locks its boot loader, it's specifically for that.
From what I remember, Moto has some proprietary stuff there, so cracking that will get you into a lot of legal trouble...

Wait... What? Why would someone disable such a huge feature? Also, if motorola says a phone has GSM radio and it doesn't can't you complain?
Loading GSM radio on it won't brick it as the chip is the same, MDM6600.
The problem is loading it: the different radio bootloader (that isn't the AP bootloader that is being unlocked with ICS update) signature won't allow you to.
So this is a dead end?

I am very interested in this!
I travel a lot and need gsm access in Europe and Asia.
I am tired of carrying two phones and trying to keep them synced.
With all of the smart people here we can't figure this out?
I remember enabling the fourth band on my Moto GSM E6 rokr, which was also turned off by the carrier.
feel free to correct me if I'm wrong
But from what I understand, the phone is capable of utilizing gsm as well as cdma out of the box. Otherwise when you went to other countries you would not be able to use the phone. But verizon has agreements with various providers around the world to provide gsm service. And I seem to recall seeing on my device info page, while on my my verizon online access for my bionic, a number listed as the sim puk unlock code. Which may or may not unlock the phone for other sim cards, but I distinctly recall seeing it there. So check your device info page on my verizon. I just thought I'd share because some of the answers get overlooked because people simply don't try the proper channels. Myself included. For instance, who knew that the reset procedure for the razr is explained on the 2nd page of the user manual? I had already google'd it before reading it in both the printed manual and the built in help file.

do you think American and European phones will be one in 2013?

the s3 is the same build in europe and america, but because samsung couldnt get lte working with their processor in time, they used a different one in the US. most of you know this. europe is finally starting to get 4g right? (took you long enough), do you think well see the exact same model released (with just maybe different radio bands) in both?
as an american phone user, you either buy the international phone and and get development, or you buy the US one and get monster LTE 50mbps.. i want both. its not just our side that would benefit tho. development wouldnt be split between regions, it could all be shared and collaborated. well im asking if you think itll happen, not convincing you why its a good idea lol..
so do you guys think itll happen?
Most probably yes, samsung was not ready with lte based exynos soc when s3 was launched, hence the variation. If you see note 2 the spec is almost same everywhere

lol that does raise new problems that didnt exist before.. i dont know what frequencies you guys will use, but i dont think that really matters much.. every carrier will have their own radio im sure. but as long as the rest of the phone is the same, development wont matter.. just as you can flash firmware XXYZ with modem XXAB and there wont be any problems, you could flash SGS4 firmware XXXDA with any number of modems.
its also possible that samsung could release a modem with multi regional support, so all carriers could use it.. but i dont really see this happening.
As well as using different frequencies, the USA uses two completely technologies namely gsm and CDMA.
Maybe in time, the chips used in phones will be small enough to work on all the frequencies/technologies.

Verizon DNA in Europe, can't connect to 4G

i have a Droid DNA, s-off, bootloader unlocked, super cid and custom 4.4.2 with sense 6.0. i have 4G on my other phone (HTC One M7) and want to use my sim in the droid. i only get 3G. what can i do to connect to 4G?
It probably doesn't have the bands for your providers 4g
The only LTE band enabled by default on the Droid DNA is band 13.
You will have to enable the other bands to make it work.
1.) Install original factory ROM (You could use another ROM but I don't know how to get to Diagnostic mode in others such as CM11).
2.) Install a custom kernel. I has to be created from source, not stock.
3.) Download and install QPST and QXDM.
4.) Plug in phone, let it install the drivers
5.) Type: ##3424# and then hit send, let it install all drivers. This will take a while, ensure it completes before attempting to continue.
6.) Open a file browser and navigate to the "C:/Program Files/Qualcomm/QPST/bin" folder, and start the program "QPSTConfig.exe" (run as administrator by right clicking).
7.) I had two devices listed under the "ports" tab. Only one mentioned an ESN, it was the SURF9615.
Note: If it isn't showing up already under the "ports" tab, go to "Add New Port". Select the one that has 9k in it. You may have to untick "Show serial USB/QC Diagnostic ports only" to see it.
8.) (OPTIONAL, ***But highly recommended***) Now select the QPST Start Clients > Software download > Backup > Start. This saves a backup copy of your phone's stock NV memory to your computer in case you need it later. (I would also recommend that you write down the original values before you make any changes.)
9.) Again in the QPST Configuration program, go to the "Start clients" tab. Start "Service Programming" program. Select to load your device. Then click "read from device". This will send your SPC program code, which should be 000000. This will allow the next program to work.
10.) Next, run QXDM Professional (again, right click and run as administrator).
11.) Change the "view" tab to "NV Browser".
12.) Go to the communications tab in the menu of QXDM and tick the line that lists your device. Under "Target Port", make sure it lists the COM for the device that mentioned 9k earlier.
13.) Once it has loaded the NV items, go to the line 06828 and click "read".
14.) Click once in the box with the current value (should be 4096), and then edit it to be 0. Then, tell QXDM to "write" the value by clicking that box at the bottom right of the program.
15.) You may now click the box again and change this line to reflect whatever band(s) you want to enable.
Now, do the same for 06829.
Tip: You can calculate your own values for this or download the program called "Qualcomm NV Calculator" (It is free). If you use this program, you will use the LTE Bands Calculation tab. You will need to go to the menu in the top right corner and select "LTE Bands Calculation" and tell it that you want to "Use QXDM Notation" in order to get the right values. Enter the decimal result for the 6828 & 6829 values.
Reboot your phone. It should now have whatever bands you have selected enabled.
I know this looks tedious but literally takes about 30 seconds after doing it a few times.
Note: Other programs that you may find useful are "LTE Discovery" and "Network Diagnostics".
did it a 100 times.. with all the band combinations that i could get out of that program.. still not getting 4G signal.. so i think i won't be able to use 4G.. will stick to the 3G. by the way the bands for Romania are : 3,7,20. in NV the code is : 524356

Sorry to hear that it didn't work. Many qualcomm devices are capable of all bands, but it is possible the DNA is not. I did notice on my device that 4G seems to be disabled altogether when I did this on Verizon. So, maybe there is something I've missed.
maybe we are doing something wrong.. i see that more Qualcomm phones are able to see more lte bands (see oneplus one).. so maybe if we use a CM ROM?? i guess it could be ok, because in Diag (*#*#4636#*#*) after selecting LTE it goes back to WCDMA in a flash.. after unlocking all bands when i select LTE is says no service.. so who knows.
The 4G radio in Verizon phones is drastically different as the frequency is different. It isn't AWS like a majority of other 4G radios. Sadly it might never work without changing the hardware out which will cause major issues.

This may not be completely accurate. This method has been used on several devices it would appear: http://forum.xda-developers.com/showthread.php?t=2291589
Also, if you look down in this post, it appears that some phones require you to manually select that you want to activate the bands by dialing *#2263# (or some variation of this) and then selecting the bands that are desired: http://forum.xda-developers.com/showthread.php?t=1547114
It may* work on the DNA. In the end, this may be a hardware related issue, but is is likely just a software related one (I believe). I honestly believe this is essentially the same hardware as the Butterfly with different radios and software. It is fully capable of using the bands you are wanting. However, this is just my theory and remains to be proven.

Those aren't Verizon variants. Those are phones that were built with AWS in mind. The DNA is a CDMA phone with a few GSM bands built into it because Verizon told HTC they wanted a global phone and told them the bands they wanted and the ones they wanted excluded from the phone. There have been ex DNA and ex Rezound (another HTC global phone for Verizon) users who have tried for quite awhile in trying to get these "magical hidden" radios to work and it all came down to that they aren't there in these variants.
You can search and dig up old DNA and rezound threads from years ago and see the amount of work done.
Edit: Checked the old threads. The GSM bands for the DNA is as below. It doesn't support the 1700/2100 (ul/dl scheme) of AWS LTE as it is missing the 1700 in its radio altogether. The phone would need both 2100 and 1700 in UTMS to allow the correct 1700 up link and 2100 down link connections. This phone just lacks the hardware.
It wasn't made to be a GSM only phone. It was initially meant to be used on Verizon and work on international carriers when going on holiday.

I appreciate your input, but did you read the OP or my posts fully?
If you did, you should realize that I fully understand that the Butterfly isn't a Verizon variant, it is the other way around. I was suggesting that there is a possibility that the phone might be able to unlock additional bands because it is basically the same phone as other GSM variants only branded and modified for Verizon as you can see here: http://www.gsmarena.com/htc_butterfly-5118.php
This has been done in the past with other devices including Verizon devices such as the GS5, LGG3, etc as discussed here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
While, I expect you already know this... It all boils down to the fact that R&D cost money. It's often cheaper for manufacterers to slap the same hardware in a device and modify the software to the liking of carriers such as by limiting the bands.
By the way, if you read the OP you would know that band 4 LTE is useless to the OP because he is trying to the phone in Europe, where there is no carrier using that band. You list the bands that the phone has been approved for, but as I mentioned above but other variants of this phone exist that utilize the bands the OP is looking for and there is a strong chance those variants share the same hardware. As mentioned above, this has been true for many other devices. I researched the topic and never found any conclusive proof that they can't be unlocked, so I felt like it might be worth his/her time to give it a shot since the method I listed is pretty easy and safe.
The Rezound is a much different device. It has no GSM radio. I would never have expected it to work on any GSM network...anywhere...ever. About the only things they have in common are that they are both produced for the Verizon carrier and use (different) snapdragon processors by HTC.
I do appreciate your input.

The Rezound does have a GSM radio. A number of users including myself have used it on other networks. Me personally, I tested it on T-Mobile and AT&T and got edge speeds. You are discussing a carrier who purposely burned out the FM radio in the Verizon M7 so it would not be functional. While you are right, HTC might have allowed the bands be made on the radio, it is highly unlikely. Others have tried. Some have even tried doing NV edits and didn't get it to work. This isn't the first time this subject has come up. The DNA can get some HSPA bands, some have tried to get some HSPA+ to work, some have tried getting 4G to work, one actually burned out his radio doing an incorrect NV edit. It has been tested before. HSPA in the US can only work on the refarmed areas. This has been talked about. HSPA will work in other countries that use the above bands specified.
If you are dealing with a carrier that will purposely tell the manufacturer to burn out an FM radio to force internet music streaming, why wouldn't they tell them to make a special radio for their variant? The reason the SGS5 and HTC One M8 work is because of the processor used, this phone is too old to work.
LTE in Europe
Hi, I live in Europe and in my coutry my carrier provides LTE, I've done the radio change with QPST and QXDM as described in post #3, I've enabled all the bands, but without luck.
I've the latest radio and hboot, tried some build.prop file tweas for LTE as described here, still no luck.
May be it's just a matter of some other setttings in buld.prop, but after many trials I think it has to be the radio, what blocks other LTE bands.
I had a bad idea to flash the radio made for HTC J Butterfly (HTL21), but I'm afraid of it (hardbrick), rather to find out, if it is the radio, what causes the problem and if it is, than figure out, how to edit the original radio (if it's possible).
Have anybody tried edit the radio or just able to read out something useful from it?
Somebody created a custom radio for Samsung devices as described here so I think it could be possible for DLX to.
