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.
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!
Hardware..
Just a question from a newer Motorola Milestone XT720 user. Now to my knowledge, my Canadian provider Rogers runs on 850/1900 bands and 850 for 3G. Now my problem is unlike my iPhone (I currently use the sim card from my iPhone 3G), my XT720 I assume is asian and it runs on 1700/2100 as most of you already know. So before I which to WINDmobile, which like T-Mobile runs on 1700/2100 and is the only Canadian provider that offer this, is there any way of flashing a rom to trick the device to change frequencies or any other techniques, or will I just simply have to switch over to WINDmobile services (unpreferable since it's a newer company, still not alot of coverage without roming fees)?
they're using different hardware, so no.
Ok thanks, that's all I needed.
Hi all,
I was wondering whether there would be any way to flash a custom modem or a ROM that would unlock the LTE bands so that the Vivid can access HSPA on Tmobile's network?
From what Ive read, the AT&T GS2 Skyrocket and the AT&T Galaxy Note have been unlocked through this method and Im not sure why the Vivid cant be since it shares much of the same specs between it and the Skyrocket & G-Note
Thanks

No that isn't possible, tmobile and att have different bands. I know that you could use a sim card on the vivid, but you wouldn't get the same speed.

IIRC you can use a T-Mobile phone on ATT and get 2G but can't use ATT on TMO.

No. The LTE Band will never work on T-Mobile's GSM. What allows the Note and Skyrocket to work is that they have the pentaband hardware GSM modem and flashing a different software modem enables access to those frequencies on GSM.

Uh yeah, it's going to be hard to get the LTE bands on the LTE radio on the phone to pick up UMTS/HSPA signal.
There's a reason why phones are usually advertised like:
GSM/EDGE 850/900/1800/1900MHz
UMTS/HSPA 850/1900/2100MHz
LTE AWS700MHz
They kiiiinda aren't interoperable. Note how you can't connect to UMTS 900MHz or use a Telstra LTE phone and get 1800MHz 2G service if the phone doesn't have that band in its 2G spectrum.
I remember reading about the pentaband radios having UMTS/HSPA 850/900/1700/1900/2100MHz. That's still pretty different than your standard quad-band GSM radio.
It is absolutely possible...given that the specs on GSM Arena and Phonescoop are right...
700 MHz Class 17, 1700/2100 MHz
It has the correct pair for Tmobile.
The only thing is whether or not you can flash the radio with a Tmobile equivalent (Amaze?) radio.
What happened to all the hardware hackers on this forum? It seems as if no one knows ANYthing about the interworkings of a network anymore.
Anyhow, the phone having the bands and knowing what to do with them are 2 different things. For example. Stereo FM 101.9 Mhz vs. HD(Digital)-FM 101.9...they're both on the same band/frequency but are utilized differently...
The signals are still transmitted on the same frequency, however the radio itself doesn't know how to decode/interpret the HD (Digital) signal...unless it is told how to do so.
The only place that this analogy differs is when it comes to actual comparison of FM receivers and Cellular phones. With FM receivers it actually requires a decoder to understand the digital signal being broadcasted...Cellular however just needs to be flashed and voila, you've got HSPA...
So. Yes. It is %100 possible.
NO NO NO NO.
LTE bands do NOT equal GSM. Not going to happen. They are physically different receivers for lack of a better phrase. There is no way to do this without physically changing hardware. Also, you realize T-Mobile's "1700" frequency does not actually mean 1700 on the dot. They use a different subset of actual radio bands than AT&T's 1700 LTE. As in 1721-1727 or some such vs 1781-1793 or something. I don't know the actual frequencies, but you get the drift.

It is absolutely possible. No question about it.
Then do it. For one, there is no compatible modem to flash. Two, it isn't possible.

Hand is hitting my face so hard right now.
RavenII, if it's so possible, then why don't you do it? If you can't, give a large donation to one of our developers and tell them to do it.
I, and many others here are blatantly telling you it's not possible for clear reasons.
The Galaxy Nexus has a PENTABAND UMTS/HSPA "3G" radio. 850/900/1700/1900/2100. That's why it can access TMobile's 3G and faux-G. We here, on the HTC Holiday, have a tri-band 3G radio.
DIRECTLY from your sources at GSM ARENA and PHONESCOOP. I've added HTC.com for good measure:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
GSM 850 / 900 / 1800 / 1900
LTE 700 / 1700
WCDMA 850 / 1900 / 2100
LTE (AWS/700), HSPA+/UMTS Tri-band (850/1900/2100MHz), and tri-band GSM/GPRS/EDGE (850/900/1800/1900MHz)
What? I'm sorry, I couldn't hear you over the fact that "3G network/WCDMA/HSPA+/UMTS" doesn't have 1700MHz. Oh wait, I couldn't hear you over the fact that TMobile's faux-G is not based on LTE, nor is it 4G (big hint: it's 3G HSPA-based service ).
GSM Arena and Phonescoop also do not account for the of LTE bands supported by the Vivid. Each region of the Holiday pretty much only supports the LTE band in that region. Rogers and ATT only supports AWS700, Telstra only supports 1800, etc.
I'm glad I'm not the only one to retain my senses about this. Leave it to a fellow Saab fan to explain it correctly.

Ok...I really didn't want to do this since I HATE spoon feeding people on forums...but here goes. And try to keep up because I'm only going to dumb it down so much.
What you guys are mistaking for "Bands"...really ARE NOT BANDS....there is NO SUCH THING as an LTE band...or HSPA+ band...
There are Network types ...LTE, HSPA+, -Insert other modulation/channeling scheme here-, etc.
There are Frequencies (which are actually specific ranges but for the sake of confusion, they're referred to as the following 700, 800, 850, 900, 1700, 1900, 2100...etc.) By the way...all those frequencies fall under the UHF band...
So far we've established that there are Network types...and different frequencies...are you still with me? Any questions?
Ok, onward.
There exists something called an SDR or Software Defined Rado...it has the ability to receive and transmit on certain frequencies...It's the software that defines how much of that frequency to use per channel (1Mhz, 25khz, etc.), what range of frequencies to use, how to use them, how much power to use while transmitting, among MANY other things (what frequency to send on, which to receive on, etc.)...That's how they came up with "Software defined radio"
If you look at the Product Brief for the MSM8X60/APQ8060 you should notice all of the frequencies that these specific chips support...
I really don't want to lose you guys, still following?
You might notice that the APQ8060 doesn't have a WWAN modem...but what does THAT mean? It means that it needs something like ohhhhh let's say the MDM9200...FINE! Here's one more spoon full
Reader to me: But RavenII...you're being a condescending ****, and we still don't know what the hell your point is...you're spewing all this **** like you're some know it all...
Me to Reader: There there grasshopper. I will get straight to it...
With all of the information I've given you...you should be able to see that when you see something like "LTE (AWS/700), HSPA+/UMTS Tri-band (850/1900/2100MHz), and tri-band GSM/GPRS/EDGE (850/900/1800/1900MHz)"...it means the radio is...
Being told to use LTE Standards (modulation, channeling, frequency steps, etc.) on AWS/700 (which if they're using AWS to signify Band IV...it would in turn mean 1700/2100), HSPA+/UMTS Standards on 850/1900/2100MHz...etc.
Still reading?
When I say that it is %100 possible...I'm saying that with software or "flashing the radio"...you can effectively change/tell what the chip should do (in this case either an MSM or MDM) with the frequencies it's capable of transmitting/receiving on. That's it.
Aus_Azn: I really hope you didn't leave a hand print on your face...
Thank you, good night.
One last thought: I never said that I would do it, I said that it's possible...
Here's the real simple way to explain it: it is theoretically possible to do but no one outside of HTC has the skill or proprietary code to do it.
So for all intents and purposes, impossible. It will not now nor ever happen.
Also, while the chip may support all bands from the factory that initially fabricated the chip, it may be locked at a firmware level (not a software radio, but actual ROM on the physical chip) that a software based radio cannot affect. This is why you can't just flash a T-Mobile software radio on another AT&T s-off device and have it work. The physical chip itself DOES NOT SUPPORT THE FREQUENCY NEEDED due to changed firmware configuration.
Is that condescending enough for you?

Let's see, how can I put this...You're still wrong. It's still possible.
I don't even own a Vivid so I'm no longer going to post to this thread...but I will tell you this...everyone once told me that blackberrys could not have data without having the BIS (Blackberry specific plan)...and guess what. I'M the reason that people are hacking them away. I was the first one to figure it out and prove everyone wrong. While I don't have a phone that I need to convert for T-Mobile, you can bet, that once there's a phone that I want to use on T-Mobile's network...I'll more than likely find a way.
Farewell.
@totally off topic
RavenII I think you're going on the right track here. I'm already convinced by what your saying.
peaceout
What RavenII is saying does have a good base logically because it has been done before for a very similar set of hardware to the raider. The ATT Galaxy S2 Skyrocket and the ATT Note LTE are both phones featuring very similar processor and modem as the Raider. The APQ8060 and MDM9200 (i think).
Samsung released devices with this modem running on all sorts of bands 1700, 850, 1900, 2100 and even LTE on 1700 and 700.
The ATT Versions of the devices do not feature UMTS in AWS range however people have simply flashed the modem from the T-Mobile version of the device which doesn't have LTE and the ATT LTE devices actually started working on UMTS AWS bands. Various modems give various degrees of success but it is possible and has been confirmed many many times over.
Here is the thread for the ATT Skyrocket. You will find people doing the same thing on ATT Galaxy Note LTE.

You guys are funny, now I can't wait to get my Vivid which I just received today running on T-Mobiles "4g". The funny thing about this is when i very first started reading this thread and saw Mr. buknastys' reply, I was thinking "That is absolutely not true". Now I'm not going to go into detail or try and prove any points, as Raven has done a perfectly fine job proving his point and answering the OPs question. Bottom line; the two readers are absolutely wrong and Raven is absolutely right. Also one last thing, I love how suddenly a firmware "lock" is something of an obstacle, yet we have gained S-Off on nearly every HTC bootloader out there. Just sayin..

I would just like to say thank you to Raven as I now have a AT&T Vivid and have successfully placed it on the T-mobile 3G network working 100% of the time. I will be putting together a full tutorial on how to do this shortly as it was indeed a challenge. I have been reading these forums for awhile and Raven your post has by far been one of the most beneficial and inspiring ones...thanks for sticking it out on these forums...few do these days. I actually just joined this forum after months of reading because of this post. I figure i too will provide feedback. I am actually a Tech Manager w/ Sprint. I work on these things everyday in other words....hints why I actually have a T-mobile phone lol. Not saying T-mobile is the best but you at least get exactly what you pay for and they are honest about coverage haha. Anyways..back on topic...the HTC Vivid is an interesting phone to root even and get the S-off. It is needed in order to get the sim unlocked. You have to do a combo of the rooting kit "Vivid_All_in_One_kit_v2.2" posted on another section and the "ControlBearRelease_holiday_ICS_WIN" (if your running Win 7). After you do what they call the "wire trick" (basically short the sim reader temporarily to allow temp access to flash) you can get the sim lock off. After that it is simple trial and error with modem flashes from various tmobile devices onto the HTC Vivid to get the 3G up and going. Mine actually kicked on with the AT&T radio flashed at first but I only had coverage in certain areas. Basicly it will depend alot on your local towers. Believe it or not...ALL CELL TOWERS ARE LEASED FROM VARIOUS COMPANIES LIKE SONY ERICSON WHICH MAINTAIN THEM ALL ALMOST!!...therefore it is very dependent on the towers in your area which radios are likely to work if not the stock modem on the device. It depends on what lease and roaming agreements are in place in your region....again...I WORK ON PHONES EVERYDAY FOR SPRINT...know a little about all that stuff...trust me...i have people yelling everyday about not having this or that when most of it is the carrier hasnt signed an agreement with Kyocera or whom ever to support that device or the lease contract has expired and will be resigned in a few days....bottom line is ....if the phone has a radio chipset that supports multibands and frequencies it is almost always possible to do what ever you would like with it. As far as firmware lock....too funny...those do not work on Android devices as the chipsets were intentionally designed to be unviersal to all carriers to cut manufacturing costs...much like in automotives where Mazdas and Fords use the same parts...just a reference. Anywho....It really is possible...it just takes research and a TON of time sometimes but that is the point of hacking....most would have said the Xbox Kinect wouldnt have been able to been hacked or the Wii remote seeing as both those use internal chips that range in the thousands if sold for other purposes. Long story short....happy hacking and Thanks to all of you for a great discussion forum.
I bought a chinese version of the HTC one M7, it's called 802W over there, which has a dual sim cards.
Brought this phone back to Canada, coz I live in a small town, this phone won't pick up the frequency from bell (so means no signal at all)
but it works with other sim cards from other companies like Rogers, Fido.
The bell ppl told me if I flash the rom and bootloader, I might find one that will support bell frequency.
I am just wondering if someone can tell me, is that possible? because someone else told me the phone frequency band has nothing to do with rom and bootloader. Can someone comfirm this?

this MIGHT be possible. but currently the phone is S-ON which means its security locked on. without the security being off we cant access the particular section of the phone where the radio lies. until we can theres no option to adjust the radio frequencies(we dont even know if this is possible). so UNTIL we can get s-off this is a very very very far speculation.

You can actually flash a different radio if you are rooted. But I assure you it won't magically switch frequency bands. It's the hardware that needs to be changed for it to work.
Tried it already and no go.

I bought and htc one from hong kong and it was not working on the 1900 freq. I dig out from internet the following, the specs you see for the htc one dual sim in every auctions and even on the htc website is the specs for the htc one (normal one, no dual sim and no microSD). the dual sim desing was only made for china.
aparently they removed the antenna for the 1900 freq (which is not used in china, since they only have 850 and 2100 band), the space that the 1900 band antenna left was used to adapt the microSD and the dual sim. it seems that the dual sim is a pretty good demand in china since they are a grown economy and people needs to have 2 active line (reason why you will see also a samsung galaxy S4 dual sim).
So unfortunally there is no way right now you can make it work on the 1900 freq. unless you have the skills to open the device and replace the 2100 antenna for a 1900 one, and reprogram the entire phone.
wow but at&t is 1900
