Band Upgrade Question - MDA II, XDA II, 2060 ROM Development

Is it possible that a future ROM will include 850 Band in addition to 900/1800/1900? Or is that a physical limitation of the device's radio?
Sorry if this is a dumb question, but I have not seen any info on my search of the forums.

Offer $300 for T-Mobile UMTS

If anyone can get my Pro to work on T-Mobiles 3G network. I heard they are going to carry it and that hardware is the same its just the software....
Shoot me if its not passable but im trying :/
Wow, that's practically a 3rd of the devices price :O. I'm sure people would help you without offering the money. I would wait for the cooked ROMs as the might just fix the issue.
O yea
EDIT: You have to show me how to instal it and give me everything I need to instal it
thanks

I assume you're kidding right? As the Raphael forum is brand spankin' new I'll throw you a bone and guide you to ROM upgrading guide for the Kaiser from the Kaiser's Wiki. Upgrading the Raphael's ROM will be similar. BTW, seems nobody knows for sure if the UK version of the Raph has the necessary hardware for UMTS with AT&T or T-mobile.

Thanks for the help.
Im just lazy to look at all the numbers and roms and threads on if and what works. I just want the radio for 3g T-Mobile to work. It be nice to have some other cool features as well but I really need 3G
thanks again
Yea, as i stated earlier, you have to try out the different ROMs and have the exact settings to get it to work.

I heard that it can brick your phone.....
thanks again
If you follow the instructions, you should be good to go. Just read and once you feel comfortable, do it.
See theproblem is its all over whelming to me.
I don't know if its 1700 or 2100 the phone has to have to work on tmo. And I also seen that the diamond shows 1700/1900 and 2100 umts but they are not active when someone selects it....
Kind of understand my position?
Tnx again for your reply
GlobalM3 - why don't you call TMO support phone number and ask which band to choose for 3G? Probably you also need to try to activate hsupa/hsdpa.
p.s.: anyway you should flash your phone to newest rom and radio available, possibly the fix is already in it...

t-mobile uses umts 2100
it not being active can have many origins
u need a abbo for it , a login, server ip etc
best to check with the customerservice or on the t-mobile website
you can register your account there and the phone
once on the customerpage of your account you can choose to have the settings send by sms
this will auto-configure the proper settings
Guys I am referring to T-Mobile USA 3G not Euro T-Mobile.
THanks for the shot at help

Well that's propably why you'll be seeing Rom's being singed to flash to Oli's SPL just like in th Diamond forum's
The main setup is safety.
Bricked devices being sent back to the Provider or HTC is in no one's Best interest (Excuse me if i used the incorrect phrasing here, but you know what i'm trying to say)
Heck i think if you donated 75 to XDA and 75 to anyone willing to help you flash and get the right tools there'd be plenty of users willing to help you out.
I think the most posters above are only trying to save you some money.
You'll need to flash a radio ROM from the AT&T ROMs. In fact, if you can, flashing the whole AT&T ROM may help.
I know AT&T and T-Mo USA have different bands, but the AT&T ROM is the only US ROM/Radio ROM, and so is the most likely to work (unless the devices ship with a radio ROM that covers all bands).
ROM flashing may come with a risk of bricking. Nothing is risk free, but the official RUUs are likely to work best (if the device is not CID locked that is)
Then I will donate some of that money to XDA
I wonder if att has the right band... but why would it :./
Thanks
It may not have the right band, but it's the only radio ROM that'll work at all on US 3G networks.

So you are saying that the radio supports it but no the software?

I don't know. But without the software, there's no change the hardware will work fully.
As stated, T-mo US uses UMTS 1700 and 2100. The problem is T-mo is separating HSPA between the two bands: 1700 for the uplink (HSUPA) and 2100 for the downlink (HSDPA). I may be wrong, but I don't think any other carrier does this (AT&T 3G uses 850/1900, but both links are available in both bands).
It is unclear at this time whether any of the radio chipsets in current Europe/Asia 3G handsets can support this split implementation, henceforth referred to as AWS (even though AWS is a bit of a misnomer, since AWS refers only to the US 1700/2100 frequencies and not necessarily the split-HSPA configuration T-mo US is using).
We will probably have to wait until T-mo/HTC puts out an AWS-capable device and dissect it to see which radio chipset it uses. If the Pro has the same chipset, there might be a good chance of flashing the radio to support T-mo 3G.

[Q] Question: Possible to hardware enable AWS on x10a?

Hi all,
I've been reading as many threads on the internet (google is your friend) about the ability of the x10a to work on the AWS frequency band used by windmobile. Dispite some misinformation about this, the general consensus is that the x10a hardware does not have the radio enabled. It is not just a firmware setting.
Now, I've seen the thread about the disassembly of the x10 elsewhere on xda and I that made me remember the old Athlon CPU days when you could enable higher speeds and such using a jumper on the CPU. I looked at the specs for the Qualcomm radio linked in the same disassembly thread and it looked like the x10a processor could do everything that the x10i processor could, plus more. So, I'm wondering, could a simple jumper setting enable the AWS band on the x10a?
Any feedback would be appreciated.

[Q] P7500 with AWS radio?

I have a P7500, and actually wanted to know if anyone had attempted to flash the radio to support AWS bands. From what I have read, the T859 is the same Tab with the exception of the bands.

Going by experience of other devices, the frequencies of the networks require the bands to be physically supported at hardware level, of which, the radio hardware will be physically different, so flashing a Radio firmware other than the one you should be running, will probably only end on tears.

[Q] LTE band 3 (1800 mhz)

Hi there- I've moved to a country where the LTE is on band 3, or 1800 mhz. I know that with some phones, firmware updates/flashes enable frequencies not previously available. Is there such a thing for the AT&T HTC One? I thought there might be, given some editions of the One support 1800, so I thought maybe it was a dumb artificial limitation imposed by AT&T.
This country also has a "TD-LTE" freq of 2300, but I'm afraid I'm not sure what that is.
Thanks in advance for any help!

Possible to enable additional LTE bands on KIW-L24?

Hi all,
I was wondering if the Honor 5X was capable of having additional LTE bands enabled, specifically bands 3 and 8? According to GSM Arena, the non-US versions of this phone support that band. I've seen that some other phones, such as the old Nexus could have additional bands added.
I'm a newbie to phone hardware, so apologies if this is a dumb question.
I'd like to know the answer to this question too. I found this thread on the very same topic, but for the Nexus 5. It serves as a good place to gather relevant info, and learn about the problem.
What I've gathered so far is that a phone needs a couple pieces of hardware (Radio Frequency Front End components Filters and Power Amplifier Module) to enable a particular LTE band. We can find this information if we have a service manual. Do you know if we have one available for KIW-L24?
If the hardware is available, we may be able to enable it by editing an Android OS system file (not exactly sure yet).
If that doesn't work, we'll have to edit the qualcomm radio firmware, enable the bands, and flash it back to the device. I think we'll need to find some leaked software from qualcomm to do this (QRCT-TOOLS-NV Manager or something)
I have this same problem. but Flashing it with another region firmware say Indian version of honor 5x that has band 3 and 8 will it work? I learnt the American version has it but locked.
I support this question too. I would be very grateful with the one capable of answering it. If the hardware in different versions of the phone is exactly the same, then one should be able to, at least, enable all the bands supported by those different versions.
Did any of you have a solution for this?
I am also looking for having/unlocking additonal bands on the device.
Thank you!

As of my knowledge, Honor 5x doesn't have capability to support additional bands from the hardware perspective. Thats why each region has each build with different model number supporting their respective region bands.

Non sense , when you said that it's like saying huawei built each honor 5x with different hardware which is not true only the Kiw-AL10 is different, the LTE bands are just locked on each device.
I think you will need some huawei honor support to know at least which hardware antenna is present in your kiw_l24.
I guess with google you can not find the hardware layout of honor 5x or which component is installed.
There are two cases:
1/ hardware antenna for a specific band is present but not used (usecase: for certain country, Constructor is validating only the corresponding bands)
--> you can here flash a firmware from another country to be able to use these bands
2/hardware antenna for a specific band is not present
--> you can do nothing
You can try to flash firmware from other country (l22 formware which support band 3 and 8) but i guess it might brick your phone.

The same issue
Any news about how to enable the frequencies in the model KIW-l24?
