Changing Band on T-Mobile PocketPC 2003 (XDA1)

Hi,
My XDA1/T-Mobile PPC is on the XDA Developers SER 1.2 ROM and it has utility wherein I can change GSM mode from GSM900 to GSM 900/1800 to GSM 1900. I recently upgraded through the T-Mobile WM2003 ROM and Radio exe file. Now, I wish to have that utitlity again becuase now I am in asia and it is practical to have the GSM 900/1800. But I am also been goind to the US from time to time so I don't want to lose the 1900 BAnd. Is there a utility somewhere where I can change band?
I saw somewhere that I can change band via the bootloader: I am not familiar with the bootloader can somebody tell me how to change my band to 900/1800? Is it easy if I want the 1900 band back beacuse I'll be going to the states in a months time, and after that I will be back in Asia again (so I have to change to 900/1800 again). Pls help. Thanks.
BTW my device information is as follows:
Hardware Ver. PW10B1
ROM: 4.01.16 ENG
Radio: 6.25.02

try changing which rom you have, maybe that will change the band

Hi,
If your device is B type, that means it's 900/1900 MHz (plz refer to the rear sticker and don't rely on the device info data!) ... so, in Asia you are stuck with 900 MHz ... anyway, changing the band from the bootloader is not that safe action ... some times it make the xda hang a need a many hard reset actions to get back.
I would advice you to get XDA II which is tri-band by design.

The latest official US T-Mobile ROM v4.01.16 still allows the bands to be switched within the OS, whereas with the latest official US ATT ROM vA.30.09 said to be able to switch automatically.

Thanks for the replies. So it is not recommended to switch bands with bootloader?
reydiodj: What do you mean by switching bands within OS? Does that mean I can still get 18000 frequencies?[/b]

thanks for the replies. No need for me to change the band, my device already works perfectly now.

Can't access 3G mode

Hello , the problem I'm having is that I can only access G "Edge". My phone was branded to telus (CANADA) carrier , but now is unbranded and has official sense 3.0 rom , using greek carrier cosmote phone supports 850/900/1800/ 1900 and UMTS /HSPA 850/1900 mhz. Any help ?

if you dont mind rooting your phone , then install another ROM ( custom or not) , and see the effect always a good solution
might work on other kernels/roms
cheers

Nothing you can do. The telus and inspire(us dhd) support different frequencies for 3g(850/1900) than europe(900/2100).
Only way to get 3g is to get the European dhd

Upgrading to Bada 2.0

So i have a Canadian Wave S8500 running 1.0, I have flashed a Europe O2 firmware for 2.0 and WOW is a major change the only problem is the modem, my SIM no longer works. I tried flashing the modem from Bell Stock firmware but it failed.
Anyway to flash the modem?
ASlso Anyone can recommend a FW that works with North America?

Thanks for that, i never knew you could SIM unlock for free now, it actually worked with my Rogers SIM eventhough its a Bell phone. My problem now however is that it only works on Rogers, it does not work on Bell. The SIM is detected but cant make calls and this is likely because of a UK modem that does not support Bell frequencies. I need a North American Modem for Bell/Rogers and Telus.

Bell/Rogers are the providers? On what freq they are working? Because wave 1 is working on this
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 2100
HSDPA 850 / 1900 - North America
I try to help but i think you need help from someoane who understand modem functions....

yeah i tried looking for compatible firmware for NA but have had no luck.

[Q] US t-mobile m8 using HTC_001 firmware bands

Hi All,
I want a 32GB version of the m8, saw US t-mobile version which the following bands:
2G NETORK: GSM 850 / 900 / 1800 / 1900)
(3G NETORK; 850 / 1700 / 1900 / 2100)
(4G NETWORK: LTE 700 / 1700 / 2100)
I use UK EE 4G which uses a different band.
If I S-off and flash HTC_001 firmware will I get EU band support or are there these limited to hardware?
Thanaks in advance

Band support can be added (changed) by flashing the appropriate firmware. New with the Snapdragon 801 is that the band support is software based.
Although you might want to also change the ROM also, if not already. Your carrier and the radio might not play well with the stock ROM's build.prop. Its happened on other carrier versions (causing various network issues).

need some help to change radio basebands on htc one m8 gsm

Hi.
I need some help to change radio baseband on my m8 (0P6B130) so LTE/4G works with Telenor Norway ( https://www.frequencycheck.com/carriers/telenor-norway ).
it's s-off and cid 11111111
currently running: RUU_M8_UL_M60_SENSE70_MR_BrightstarUS_WWE_6.12.1540.4
have tried this rom also, without getting LTE/4G working: 0P6BIMG_M8_UL_M60_SENSE70_MR_HTC_Europe_6.12.401.4_Radio_1.29.214500021.12G_20.72.4196t.01_release_464360_signed
ive found this: https://forum.xda-developers.com/showthread.php?t=2736921
but not sure what image will work for me, if any.
if possible i have another m8 (OP6B100) working with LTE/4G, if there is a way to read/save radio from that one and move to my new phone?

What LTE band(s) does your carrier use?
3G works okay? Or how about 2G data?

both 2g and 3g working 100%, im only missing working LTE/4G.
as far i figured out my carrier Telenor Norway use B3 B7 and B20 for LTE/4G.
but i can not figure out what radio that supports those bands and to try out

According to these specs, the Euro version should support those bands (1800, 2600, 800 MHz respectively). Which would go along with the statement that you have a model OP6B100 which as working LTE. But it doesn't explain why Euro RUU 6.12.401.4 doesn't give you working LTE.
Does the APN on the working (LTE) M8 match what you have on the other one?

the one im missing lte on is a 0P6B130 as statet, its my old one that is OP6B100 that have working lte.
apn match, and verified with settings off carrier website

I understand that already. All these phones are the same in hardware, the band support is (supposedly) determined in the radio baseband firmware. What I'm saying, is that one you flashed the 0P6B130 device with the Euro RUU 6.12.401.4, it should (in theory, at least) have the same band support as the OP6B100 (Euro) device.
However, we've seen this before, where M8 devices have been properly "fully converted" to another region/version, but will still not get LTE service in that region. We've seen this a number of times, and I have not seen any good explanation, and unfortunately, no solution.

thats what i thought after a few days googling, and reading around in here too.
can it have been some fault in flashing of radio even it said right radio version in hboot and android?
is there a rom for just flashing radio from the 6.12.401.4 RUU ?
tried to make backup of radio on OP6B100 from adb shell, but its not rooted so that went nowhere
