Diamonds are Tri or Quad band physically? - Touch Diamond, MDA Compact IV General

As many of you may have already noticed, many of the Diamond's spec sheets say that the device's radio is capable of operating in all bands. Official word is that the device is tri-band (America or Europe). Is this limitation based on the settings for the rom or radio.
In other words, is it try or quad physicaly? And if it is, is somebody going to release a cab to enable it?
Regards,

The chipset is capable of using other bands, but there is no antenna for these other bands. I am about 80% sure that in that case calibration data for the other bands will be missing in the Radio, and those bands will therefore be disabled.

S730 for the US 3G quad band, will present S730 be upgradeable ?

I read that the official release of the S730 for the US will be 3G quad band.
I have a S730 thats is only for 2100. Will be the implementation of the other frequencies be software or hardware based ?
If it's SW would it be possible for my phone to work in quad band ?
Any ideas ?
If they included the radio for the other frequencies than a software flash should make it work, but I doubt they put the radios in for our frequencies here. I would be interested in knowing as well, but we shall see as the time gets closer
This was linked in another post. So their choices are clear, hopefully they chose to use the chip that supports all the freqs; but I doubt it, since the model IDs are different: WING220 (the EU version we all have) and the WING200 (the North American model).
Now let's see someone get the TV out working.
Seriously, we will see if writing NV item 0148 can also fix this issue.

Are all GSM Diamonds identical hardware wise?

So I'm going to buy a Diamond. I have 2 options. One is Tri-band and the other is Quad, but it will cost me $200 more.
So if I'm not mistaken, the hardware is all the same so all I would need to do is flash it to unlock the 850?
Thanks.
Actually they are not the same. The European Diamond does not have the hardware for US 3G. If you need 850, go for the quad band.
the indian diamond is not 3G at all...it's got a different processor MSM7206A for 2G (the default diamond processor is 7201) with the same 528 mhz speed
except for that, all other hardware is identical to the others

That is 100% untrue. The DIAM100 does not have a WCDMA 850 radio in it, and the DIAM110 does. Aside from that, there are also other hardware differences among the different iterations.
oh ok, so not all diamonds are the same?
That's no good. Is it written in the back of the phone exactly which model of the diamond it is?
So which is the model where I can unlock the 3G?

is the USA 3g band going to be a software or hardware update?

My understanding is that there are people who have the TP2 activated here in the US...
but 3g doesn't work since it uses a different band in EU
so...the million dollar question...
is this hardware or software issue and eventually fixable with a rom upgrade in the future?
thanks for your input

Since the hardware is very much like the Raphael hardware I would guess that the correct hardware needs to be in place for US 3G. I hope I am wrong since I have a euro version TP2 here in the states.
yeah...its looking like hardware...
It is a hardware thing. They are on different bands (Quad band and tri-band).

I dont think it is even bands...my TP2 is quad band I believe and can not get 3G with AT&T.
Bands for my phone Quad Band 850/900/1800/1900
yah plenty of US ppl have them but the euro models only have 3g on 2100mhz (basically wifi???)
usa 3g is on different band...
the quad bands are for phone use (i think...but i'm a noob)
att 3g is 850.1900 tibble is 1700 and telstra is 850/1900
so if i understand it right...to gain 3g on different band besides 2100 (wifi/eu) you are looking at hardware

what does wifi have anything to do with this?

forgive my crude interpretation
some of it is sticking though...lol
If you purchased a quadband unlocked TP2, you will never be able to get US 3G on it unless you can get the hardware modified (which in all likelihood, you can't).
If you have a TP2 with triband then it will either support AT&T (850/1900/2100) or T-mobile USA (850/1700/2100). A phone model will probably not come out that supports both T-mobile and AT&T 3G frequencies. This would require a quadband phone with (850/1700/1900/2100). A phone with all four of those frequencies has never been made.
EDGE will work on almost all carriers, world-wide, on a quadband phone EDGE will work on most carriers world-wide on a triband phone.
850 is mostly used for EDGE (both up and downlink). 1700/1900 are commonly used for uplink 3G. 2100 is commonly used for downlink 3G.
I hope that this clears things up.
As mentioned above, internal hardware is almost identical as the Raphael.
This thread gathered the most information for 3G Raphael in the US.

So probably hardware and no go although LTxda mentioned bricking his Raphael trying to get 3G working with Elite's team and cmonex, so maybe she as something to add !? =Þ

[G1] Flash radio image to change HSDPA bands?

Hi,
I'm a new member to the forum, although I've been lurking for quite some time now. My interest peaked recently as I acquired my very first Android device, the HTC Dream.
I realize this may be an offshoot, but is it technically possible to flash a radio image that switches on / uses a different HSDPA frequency? I read that the G1 uses the RTR6285 chip, which purportedly supports the UMTS band 5 (850 MHz), even though it's not officially supported by the G1. Unfortunately, this is the only 3G band currently in use in the country I live in, which means I'm left with EDGE over the GSM frequency.
To put it simply, I'm looking to unlock the radio chip's frequency. Is this at all possible in software, or would a hardware mod be needed?
Thanks!

Looking to buy OP 3T; couple questions

Hello,
I'm planning to buy this device, but it's the Chinese model. I have found a good deal at 419 USD for that specific model. I have two questions:
1. The hardware difference in Chinese and European variants is ONLY in the modems, right? Otherwise I can treat the device as if it were the European model (i.e. flash OxygenOS and all the custom ROMs here), right?
2. The device supports all of my provider's 3G bands. However, when it comes to LTE, my provider uses two bands: B3 and B20. The Chinese variant supports the band 3, but not the band 20. Is this going to be a problem in getting LTE coverage and LTE data speeds? Cause I don't want to get a phone that won't work on LTE.
Thanks in advance.
1) Yes, aside from the radio, all hardware is the same. You can flash any ROM made for the OP3T on any model as far as I'm aware.
2) Having only half the supported LTE bands will definitely reduce coverage and may reduce speed. If your carrier uses Carrier Aggregation, missing one of the bands will result in your network speed being bottlenecked by the single channel. Different bands also have different ranges/coverage area and service providers may not necessarily broadcast at every wavelength at every signal tower due to hardware limitations.
The B2 band is on a longer wavelength compared to B20, so theoretically it is slower but has a greater range.

Thanks for the quick reply. So something like this won't work in my case?
I have personally never tried unlocking additional bands, though I'm going to assume there's quite a few risks associated with the process. If you want to try, consult this guide, which was made for the OnePlus 3 and is supposedly working for the 3T as well. Use at your own risk though.
