Hello!
New user here and well, I was wondering if there's any chance that we'll be able to unlock phone bands in this device!
I also know it's probably still unclear as the phone is still new but another user said in another topic that there might be something considering OPO had some tools to unlock bands! So if anyone knows anything about this issue it'd be great!
I'd love to have B28 available on the OP3!
Thanks!
I'd say the reason of the limited LTE band selection is no other than to reduce costs in the hardware. Every band requires it's own amplifiers so making the devices regional it's an easy way to cut corners and not affecting people much (if they don't travel)

I can understand the reason, but it still seems meh to me.
But who knows, maybe there will be a workaround!
hey, ive been looking at buying an OP3 but did read that band 28 is missing which is used for faster and longer range 4G in australia and also common in the rest of asia & some of europe
weird, in this teardown it says the radio can do band 28 ? maybe its just disabled/unsupported?

Can anyone tell me if it is possible to change the HTC from a Euro phone to a North American phone by perhaps changing a chip or programming to support 850/1900 here in North America? I live in an area where 1900 is a bit spotty and I lose signal, especially inside buildings. I love my Uni, but I have too many people complaining that I'm not getting their calls and I don't get signal where other's do.
I'm afraid I don't have enough hardware experience to be qualified to even venture a guess. But shouldn't it be as easy as changing a chip or a crystal or something?
It's just a matter of both the range of the tower you're near, as well as possibly your PRL. The priority roaming list tells the phone who's service you're allowed to use. So if there's a tower within range, but not in the PRL, chances are your phone won't use it OR it will show up as roaming.
I know you can affect the 3G part of Android phones by changing the modem firmware when using Odin, and even them I'm not sure what change is made if truly any. I don't have 3g yet with my provider, which uses the 850/1900 as well, but I currently have a Euro firmware on my phone using XW Euro firmware. I'm not sure how it will affect my 3g until my provider enables it.
Other than that, I think it's a limitation of the radio chip in the phone. It may be a firmware/software setting, or it could be hard coded into the chip.. again I'm not sure
Have you seen the previous post date? lol.
Anyway thanks for your reply
Lol, true it's old, but if anyone has a solution I'd accept it. However, I've since moved on with 3 different phones including the PPC6800, the Omnia II and presently on the iPhone 4.
Thanks anyway,

No it is not possible, it´s a hardware related stuff.

Hi, does anybody know if the Gratia and Aria covers are interchangeable?
My wife has an Aria and is happy with it. I was thinking of getting a Gratia, but swapping cases so that she can have a white one on her Aria.
Given the antenna is in the cover and the phones are for different markets I wondering if the antennae might be different? Does anyone know for sure if they are interchangeable?
Thanks
I'm not 100% positive the covers are interchangeable, but I think they are. However, they aren't both compatible with the same wireless networks. You can use them both, but the Gratia won't be 3G in the U.S. because it utilizes different frequencies. It will still get data, but it will be at EDGE speeds.
Yes I realise the phones are for different markets and operate at different frequencies but I'm wondering if that means the antennae are actually different.
I noticed Expansys USA has the Gratia cover listed under accessories for the Aria,
But then what they quote for the Gratia "Mfr Part #:" is 74H01655-11M, whereas HD-Mini is 74H01655-02M (nothing listed for Aria, but I think it is also 74H01655-02M)
I'm only really interested in data in the UK on both devices, as I prefer not to pay bucket loads to the phone company when roaming, but my wife wants a white phone!
There are countless innovations of technology nowadays. There’s a fast pace of technology development even on phones. Some finest innovations of phones today are aria phones from LG and cordless phones. People keep on inventing gadgets on how to make life easier.
Doesn't the antenna just collect the signal? Surely whether it will work on a particular frequency is determined by the radio hardware in the device?
I'm just thinking - an antenna is an antenna isn't it? Same way you can use a coat hanger to pick up FM or even TV transmissions, it's all just about capturing the radio waves right?
I could be miles off base here but I honestly would have thought that the antenna that's built in to the back cover would NOT be specific to a particular GSM frequency.
Would love to know for sure though.

AFAIK, right. If the contacts are in the same place the cover should work quite well.

That's technically not true - GSM antennae are most certainly tuned for particular frequencies - if you look online, you'll see different ones with different specifications, like 850 thru 900, or 1800 or 1900. However, through some trickery, a single antenna can be tuned for more than one frequency at a time.
That being said, I have no idea what the antenna in the back of the Aria or Gratia are tuned for - it's possible they might be dual band specific to the carrier (ATT 850/1900 or Euro 900/2100) or it might be a universal one capable of picking up all 4 or more frequencies.
I'd say best bet is to get one of the other ones, try it out and see. And let us know - I'd considered getting a green one for use in the US...

I hear what you are saying but I think people are confusing the antenna with the GSM radio built in to the phone.
Whether a phone utilizes 850/1900 or 1900/2100 bands would surely be a funtion of the radio in the phone that is hard coded to those frequencies.
Isn't an antenna just "fishing net' that actually gathers the signal?
Again, could be miles off base here, just applying my own brand of common sense.

It really depends on how the antenna was designed. Resonant frequencies are generally a factor...so antenna length could matter. Polarization and radiation patterns are also taken into consideration.
That said, until one has both covers (or finds some internal design docs), it's hard to know if there is any difference.

Unfortunately, common sense doesn't really apply when it comes to signal theory.
I'm not an expert by any means, but from what I remember from a signals course I took a few years ago in college, johdaxx's and M1m3R's posts are both spot on.

Both the Aria and the Gratia work for the 4 bands of GSM, so there's really no problem if such tunning was a factor to consider.
The quality of HTC Support on this was really quite shocking, e.g.
Thank you for contacting HTC regarding the swapping of Back cover. In short to your email. Yes buy [sic] swapping the back plate can have effect on the device's perfomance. Which is why we recommend original products. Mohammed - UK Ireland Support (Tech)

When challenged he came back with:
"It does not matter which cover goes on because the real difference is the internal components."

Then...
"I can confirm that the back cover is just a bit of plastic. If the connectors will allow you to plug the new back cover in then it will work." Jason [UK - Ireland Support (Tech)

When I pointed out there were some metal contacts...
"Those connectors are there so that the phone knows that the back cover is on the phone. It has nothing to do with the signal as the antennas are up the top of the phone. "

I pointed out HTC's own support website says: "the antenna for the HTC Aria ™ is located in the battery cover."

idk man, for me that's the typical quality. I dont expect any help from any large company. For example ask any carrier's seller about batteries, they all gonna say you should fully discharge it before charging, like the old batteries. They know nothing.
But, again, both phones uses the same gsm radio freq. The only real change in hardware is the umts radio freq and I'm pretty sure the covers doesnt change cause of that. Hell, every GSM phone has a different antenna solution and they all work with the same quad band freqs
OK Back to to casing now where can u buy a white back for the HTC Aria and know that it'll work, I would love to have a white back on my Aria...
I would love to get a fluorescent green one.....
So I purchased this phone while in the UK because it looked like a solid item. Unfortunately, I neglected to realize that the default LTE bands were EU and the phone will not work in the US other than on 2G.
In the meantime... I've spent the entire day setting up the appropriate tools to modify the NV values in 6828/29 to enable the appropriate LTE bands (2,4,12) for my carrier here in the US. I've wrote these values successfully, however, no LTE. These are the only two NV values I've modified.
Is this possible? Or is there something I'm missing here and the phone chipset/radio is not configurable in this manner and requires either some other attention, or that I'm screwed.
Thanks for any insight.
Try *#*#4636#*#* which should show you network types available and if your lucky set the one you want
I see that LTE is an option here; but the radio picks nothing up. This phone comes from the factory stamped on the box with LTE bands 3/7/20 enabled.
Perhaps I should rephrase the question:
Does editing the NV values do anything, or is the radio hardware limited to specific frequencies? Or is there a way to flash a ROM or something that's not editable (i.e. via QXDM) to fix this problem? It seems like the chipsets are all the same from phone to phone, so something 'soft' must be limiting the band selection.
I'd hate to have to buy another phone simply for the fact I'm limited to 2G connectivity. I love how the government and cell phone manufacturers have the consumer's best interest in mind.

It should be hardware limitation of the chipset. LTE band support can be problematic even on high-end devices (there will be at least one band missing).
If you are in the US, why not take advantage of the Blu R1 HD deal? It's not very helpful but it's something

Hi rmbanas, how do you did it? I followed the guide from here but QPST does not recognize my device. Now Im stuck.
Im speaking from Brazil and Im trying to enable some LTE and GSM bands.
Ive unlocked the bootloader, flashed the CyanogemMod 13, released the developer settings (so as USB debbuging, etc, etc).
Certainly, it is a problem with the drivers, but Ive tried with a lot of them and still... nothing.
Thinking about this as my next possible upgrade, been with a Note 3 for about 3ish 4 years it feels like. After the bootloader got unlocked I had few reasons to upgrade. Now however the hardware is getting dated and this looks like a viable upgrade. Would this phone work on Verizon's LTE network at full speeds, I am assuming there will eventually be a CyanogenMod released for this and then all I would need to do is unlock it?
Don't count on it
It's sadly not that simple from looking into it for the Mi5... However if they make great progress with the Mi5 there could be hope for this device as well since the 820 and 821 have few differences (or none? just an OC?).
The Mi5 is able to make calls and text at the moment but the LTE is still a bit unstable. If this looks like it will get enough support I might choose it over the Pixel XL. And if it works on Verizon since I still have my unlimited data plan.
I'd like to see B2, B4 and B12 LTE bands unlockable. I'm guessing monitoring progress on the mi5 is the right move since they have similar hardware profile.
Hopefully the chip can support the bands, otherwise it's another great phone that wont see it's potential in the us/eu market.
Friends now you can lock bands and enjoy speeds. Watch this
https://youtu.be/K-DN0q64lRw
So, you lock to that b40 lte band, but, if it is faster or whatever, why it is not the default one? More to it, I thought that the device chose the best band among the ones available, so, why would locking on just this one is really beneficial? Please elaborate

because most of the time a particular band is overloaded and other band is free and if we lock to a particular band it will result in good internet speeds and coverage also. Also some people want to disable carrier aggregation as it eats lots of battery so band locking will help
and it works on Qualcomm Snapdragon also
Doesn't this mean you'd have to remember the unlock the band again if moving away from the cellular tower in case the next one doesn't support it, then re locking?, Seems only useful for when sat at home stationary where WiFi is available anyway?, Good find, but seems a little pointless imo!

Well it is very helpful in India and yes during roaming locking band on the band having long range like preferring band 3 over 40 is useful
Awesome
