Changing Band on T-Mobile PocketPC 2003 (XDA1) - Upgrading, Modifying and Unlocking

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

Changing Bands
Try,

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.

[Q] Australian Telstra Band / original firmware?

I know Telstra runs on UMTS 850Mhz in Australia, but at the moment it's also running alongside 3 on UMTS 2100Mhz (the more popular band).
My questions is what is the base firmware which has been loaded onto the phone? Is it the UK 2.21??? (which has bands 900/2100 covered) or is it another one?
Reason for asking is I've flashed back to UK 2.21 (don't ask why!) and now have found that I get my network reporting as "3Telstra" (which I'm guessing is UMTS 2100Mhz) versus what it used to report ("Telstra").
So question 2 then is if I'm running on 2100Mhz due to having the UK 2.21 sbf flashed, what should I flash to get my 850Mhz band back? Or how do i get 850 back?
TIA for any help all...
System version Blur_Version.2.26.0.MB525.Telstra.en.AU
Firmware version 2.1-update1
Baseband version EPU93ST2_U_03.03.00
Kernel version 2.6.29
Build number FRDNEM_U3_2.26.0
Try the following link to the telstra page to configure your defy for mms, and internet. I have used it many times myself after trying lots of different firmwares.

850 / 1900 / 2100 Config Files (FR/ITA/ES etc etc)

Here we are, I post the european config files for 850 / 1900 / 2100 network
You can use it on the RUTEM_U3_01.14.2 last deblured rom.
All you have to do is replace the folder in etc/system/
ATT
will those files work on ATT because of the 1900 and 850, or would I need the exact ATT version?
Yep , normaly they will work on ATT network, except for 2100 who is not present on your network. give a try.
If these files don't work , the best thing to do is reflash the original ATT rom or if you didn't change in your original rom,
and backup the frequency folder /etc/motorola/"bp_nvm_default" .
To do this you will need to room your device and pick up the folder with rootexplorer.
but normaly you won't have to do that because of the similar freQ
great!
ok, Ill try this with the newer de-blurred rom, because I can't seem to find the original att rom anywhere, hopefully this unbricks the phone!

I've flashed RUTHEM_U3_01.14.2(Debranded ROM for Central Europe) which seems to work great, but I have some issues with signal reception I didn't have with the original ROM. I assume the reason is in band configuration, according to and-developers.com, my original ROM used 900/2100 and the new one uses 850/2100. Standard for my region is GSM 900, DCS 1800, UMTS 2100.
Thank you in advance.

I just installed RUTEM_U3_01.14.2 and would like to make it support 1900 network too with your conf files, however I can't find any /etc/system folder in my phone, only /System/etc but no bp_nvm folder inside
Where do I put your files ?

I noticed the exact same thing, I have a European 900/2100 phone I'm using in Canada. My provider is 1900, so I never had 3G to begin with, but after flashing 1.14.2 my 2G reception weakened and EDGE turned to GPRS. I scared myself enough getting stuck at the Moto screen playing with basebands the first time, I think I'll wait a bit more before I go in for round two
suoko - Did copying these config files over improve 1900 signal? Did you have connectivity at all before, or was it just 2G, but after copying these new config files it is 3G?

my network uses 2100 only so 3g worked without modifications. I did this just in case I sell the phone

Can I modify or set up a band from my htc one m8 (at&t)??

Hello there guys, im wondering if it is possible to unlock a band from my htc one m8 from at&t, i live in venezuela and my current company (Digitel) the 3g band is 900, but this phone only have the 3g band on 850, my question is can i unlock this by any chances because is annoying that my phone is from E to 4G and manually i can even recive calls when its 4G and it wont change to 3g
(sorry about my english)
You need s-off by sunshine (if not s-off already). Then you can flash another version's radio/firmware to enable the desired band(s).
May also need to change CID and MID (after s-off) if the firmware is signed.

According to the following specs, Euro or Asia firmware should support 3G 900 MHz: http://www.gsmarena.com/htc_one_(m8)-6074.php
Although, keep in mind you should also verify the LTE (4G) band used by the carrier is also supported by the version's firmware you pick. You didn't state what band your carrier uses for LTE.
Also, it should be kept in mind, anytime you purchase a phone from a 3rd party source (other than your carrier) you need to do the proper research to verify the device actually supports your carrier's network. You're lucky this time (if you get the proper bands working). This is the first smartphone chipset that allows band support to be changed in software. On previous smartphones (and may also be true on other current smartphones using other chipsets), band support was set in hardware, meaning there is no way to change it.

Same as I've already stated, EMEA (Euro) or Asia supports both those bands.
EMEA is a very common (probably most common) version on this forum, so that may be your best bet as far as ease of getting the files, fellow user support, etc.

NO. The Developer version is US, not Euro or Asia. Why do you think the Dev Edition has the bands you want, or corresponds to the Euro or Asia versions?
The Dev Edition has the exact same band support as the AT&T version, so this is the exact opposite of what you want (doesn't have the bands you want).
Euro firmware is probably what I would recommend (as previously stated), and can be found on the following threads (as well as other places):

Try the SIM in another phone, if possible, to see if it works on 3G on another device.
Also, be sure the APN info for your carrier is properly entered. Double check and triple check every input to make sure every single character is correct. Even a single added space or missing character can prevent you from getting data properly.

Frequency bands

I own the HTC One M8 16Go gold Asian version, phone is rooted with ElementalX kernel but stock rom. My phone works with 700 (b28)/900 (b8)/1800 (b3)/2100 (b1)/26000 (b7). I had the TW Mobile carrier in Taiwan. I want to add frequency bands to enable 4G LTE in Canada. Most carriers work with 1700/2100 (b4).
So how to add these frequency bands?
You need s-off ($25 by sunshine app) to change radio baseband (which changes band support).
You can flash AT&T or T-Mob US firmware to change to the corresponding baseband (both support Band 4 LTE). Or the correct Canadian carrier version's firmware; if you want to, and can find it (ATT and T-Mob are probably easier to find).
But you should also verify what bands your carrier uses for 3G, and that the new baseband supports it.
In my experience, AT&T has past or current associations with some of the Canadian carriers (still has partial ownership in some); and the networks share a lot of similarities. So AT&T firmware may be the best bet.
I installed Sunshine app but can't perform any test because it says Xposed Framework has been detected. I delete it but still the same error.

Try to restore the stock ROM, then root and run sunshine.
One thing to keep in mind, its not guaranteed that you will have LTE even with the proper baseband radio firmware. I've seen a number of folks that were not able to get LTE, even after s-off and flashing the proper radio firmware (that supports their carrier's LTE band). Don't know the reason for this, and never saw a solution. But just want you to be aware, in the event you spend the $25 on sunshine, and still can't get LTE.
But the fact that the Canadian networks seem to be very similar to AT&T, leads me to think the AT&T baseband radio will work for you. Not based on any specific/exact experience, just a hunch. So don't come and yell at me, if it doesn't work!

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
