[Q] Cross flashing radios - One (M7) Q&A, Help & Troubleshooting

Hi! I am also a current HTC user(Just not one of these One series) and I would like to ask if it's possible to cross flash radios from any variants of HTC One?
The reason is I asked HTC on their official facebook pages about LTE support of the HTC one and they said that the LTE frequencies that will be enabled on the HTC One depends on what region it was released. So just wondering if let's say I would buy the HTC One from europe(Whic has different LTE frequencies compared to our country) will I be able to flash a radio baseband of a HTC One from let's say asia to switch frequencies?
The reason why I asked this is because I noticed that past HTC devices like HTC One S and One X etc. has different variants depending on what network/region it was bought.
A good example is
Can I flash the radio of HTC One which was has a uk radio/baseband into a HTC One with an asia radio/baseband?

no

You sure about that? Hmm isn't it a tedious task for HTC to make different hardware per region just to complicate things?

No, they use different bands in the hardware. Can an AM radio pick up FM, no.
US use different bands to pretty much the rest of the world. In America the AT&T model covers all america, the EU model should cover most of the rest of the world.
LTE:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz

Ok thanks! Read the info on the other thread! Anyways just to be sure I am gonna try cross flashing basebands one I get the device. At least it won't do any permanent brick anyways. I still believe it should be possible since they are using qualcomm modems on this device. And the modem I am talking about is has support for every LTE frequencies in the world.

This is not a matter of FM to AM this a matter of letting the chip recieve 87.5mhz frequency and let it also recieve 108mhz frequency

Wrong, common misconception, it does not support LTE frequencies world wide. And it is funny we should be talking about this today because Qualcomm has just 4 hours ago announced such a beast that you are referring to, so obviously it is not available in any device. http://www.engadget.com/2013/02/22/qualcomm-first-global-lte-chip/

Ok sorry I am not talking about a real global LTE support but at least. The HTC One's modem can support this LTE frequency bands.
700 / 800 / 850 / 900 / 1700 / 1800 / 1900 / 2100 / 2600
And if you ask me I think that would be enough to make 4G work on almost all parts of the globe.

Ha! I just saw an article yesterday about new Qualcomm chip that includes/supports all bands (though that may be per region, ex US, Europe, Asia). Supposed to make it easier for manufacturers to build one device, and not one device per carrier.
@OP, I would not try to flash radio not intended for your device. If partition sizes are different...brick. at least, that's my understanding.
From my Evo LTE, yup.

Sorry, but I can't really follow up know,
Is it now possible to flash a new radio rom on an US One, so it will use Europe Bands for LTE?

Incredible s with 850/1900 3g bands?

I wanted to get an inspire 4g but the crappy battery life and almost impossible to remove battery cover (for using an extra battery) turns me off so i was thinking of getting the incredible s but my provider uses 850/1900 3g bands , has a model with those working bands been announced?
well gsmarena suggests that this phone already has the ability to use those 3g bands
http://www.gsmarena.com/htc_incredible_s-3788.php
Rather unhelpfully HTC's own website only lists "AWS" as a band rather than specifying the frequencies used (though i think they may be).
http://www.htc.com/uk/product/incredibles/specification.html
Best option is probably to ask someone who's out there though i think there's been success in using this in the USA.

I hope someone in the us can confirm this!
Just got this off my INC s:
the radio freq bands mine is allowing

"26.GSM_PCS_1900"
"27.WCDMA_I_IMT_2000"
"30.WCDMA_IV_1700"
"34.WCDMA_VIII_900"
The specs for the Incredible S says basically it won't work for the provider that your using. The Bell is rumored to receive the device which means if that happened, that specific model will have the 3G bands you desire. It's supposed to be released on April 4th. It's a rumor though so don't get your hopes up.

As an employee of one of Bell's dealer stores I can certify that it's in our system but there's no release date yet.
Bell uses 3G 850/1900 HSPA bands only for their service.

vivid in australia

I just sold my HTC inspire to get a vivid..
In Australia our 3g is 850 MHz and LTE is 1800 MHz...
If I buy an att vivid, will I be able to access these frequencies? My current phone is the att inspire.
There is a leaked pic of an Australian vivid on my carrier... Can anyone tell if its the same model as att one??
I don't wanna buy the wrong model....
Here is the pic..

You will get the 3g speed but not LTE. AT&T LTE is 700MHz and the Vivid radio only supports the 700Mhz frequency.
Really? What are the numbers shown in these specs?

Pirate. Initially you said I should get.the holiday. Can you post a link showing the specs of this phone? If it operates lte on 1800 MHZ then ill buy it.
I've read that my carrier uses 1800 MHz frequency.. but also seen 1700 figure used....
My carrier is telstra in Australia.
This link explains our lte structure. http://m.zdnet.com.au/telstra-s-4g-lte-goes-public-339323055.htm
Can someone confirm to me that when they speak of lte for usb dongles, it also applies to mobile phones?
I ask because telstra has just released 4g lte for usb wireless but we dont have any lte phones available yet...
Which is why I wanna get one from america.....

Don't bother getting one from here; looks like Telstra uses a very unique LTE band. 1800 means 1800, not 1700, so the Bell Raider won't work. Just wait for it when it comes out. The leaked ROM notes that it's to be called the "Velocity 4G", so keep an eye out for it instead of trying to fish on the international market.
LTE for USB dongles is using the same LTE as the mobile phones. It's on its way. It was like that on Verizon too, with the dongles first, then the rollout of phones.
@Pirate: Has HTC released an unbranded Raider? I didn't even know that existed already.

[Q] HTC Vivid on Tmobile 3G/4G?

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.

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.

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 really didn't mean to come off as a **** in this thread, but it seems as if though people have forgotten about actual hacking and everything has moved to "Supercharging" and theming...it's saddening, I come from a time where there was no such thing as impossible.
...I encourage you to try, but do so with a lot of caution...because the fact of the matter is...you can brick your device...
Happy hacking.
THANK YOU!!!

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.

1.) the LTE Frequencies vary from country to country...
From HTC:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz

Now comes the great news.. as far as I know Rogers uses 2600 MHz . so EU Version from the UK WILL work!
99% confident
EDIT:
Maybe this Thread can be moved to Q/A
Rogers should have the phone next Friday....given that is when the pre-order offer ends
the one that available now, only has one band that matches rogers LTE band :2600
as far as i know and read from XperiaZ forum, (c6603 XperiaZ has almost same LTE band as ONE)
no one are able to get LTE.
if you need LTE. get it from your provider.

I could assume they have the US Model then? If they have the European one, all they need is the correct apns and maybe activate LTE over Settings.. DIAL *#*#INFO#*#* and then phone information ... and see if LTE is activated

as far as i know
we tried everything possible can to test LTE
last hope wehave is flash the baseband when xperia zl came out.
http://forum.xda-developers.com/showthread.php?t=2106818&page=40
anyhow
2600 is still not very realible (although i heard that one verison of Note2 that only got 2600 got LTE)
Alright so I guess I'll hold off. What band I'd missing exactly
So not 100%sure the uk version will work on rogers LTE??
how many version of htc one is there
i checked the htc uk n canada site
all the specs are the same
so ibm kind of confused
should i get that from uk or not
cuz its about 150$$$ different

[Q] International Version ???

Hi there
I want to buy the HTC ONE "again", but the problem is that I'm not sure which one.
After some research, I've found that there are several different versions of the HTC ONE:
HTC 801n ONE, ONE HTC 801e, 801a ONE HTC, HTC ONE 801W ...
Well why "again"?
Thing is that I had one until recently, the 801n, i got through a contract renewal in Switzerland, and I was very very happy with it!
But the trouble started when I went on a trip again. I travel a lot between Germany, Switzerland, Mexico, and the US, and due prolonged
stays in these countries, I have a simcard in each country, as well as prepaid and contract, each with internet access (3G and 4G).
Now in Mexico I noticed that my brand new HTC ONE 801n, was not compatible with the frequencies used here (3G, 850Mhz with Telcel Mexico), which made it useless as a smartphone. Therefore I sold it. But I loved this phone, so I am going to buy me a new HTC One!
Question is, which HTC ONE is the right for me?? Also I read everywhere on the internet about an "international" HTC one, an "international version"??
Is this one of the above versions I mentioned? "International," does it mean that it will work with all the frequencies in all the countries I travel to? With at least 3G Internet can use, perhaps even with 4G? And where do they sell it? And how can I identify it?
Thanks for your help

Not really, because already sold mine europe htc one, and looking for a new international one, which I can use in in europe and in the US, without hacking or flashing it.
And as noob in the smartphone area, i wouldnt be able to do it,even right now i am having problems to understand what they are talking about in the other thread
International version means it isn't locked to any specific carrier yoy basically any sim from any country should work. You should check that the network frequencies that the phone can handle are compatible with the country that you're visiting but a quick check of the phone specs will tell you that.

You just need to look at the table in the first post
First, find out what 3G/4G frequencies are available with what carriers in each country you travel to. Then you can pick a model that will provide the most coverage. Just going off the 850MHz 3G requirement, you have a few variants to choose from.

US and in Mexico , 3G 850 MHz , and one thing i read was that if the 850 MHZ are not supported by the phone, it seems that it doesnt matter that all other frecuencies avaible in the coutry are supported, the phone wont work with 3G, no matter what. is that right.
No beeing right now most of the time in Mexico for the rest of the year, thinking to buy the HTC One in the US HTC online shop, the unlocked version, 600 USD,
and it says
This HTC OneĀ® unlocked version comes with: 32GB of onboard memory and is SIM unlocked.
- HSPA/WCDMA: 850/1900/2100 MHz
- GSM/GPRS/EDGE: 850/900/1800/1900 MHz
- LTE: 700/850/AWS/1900 MHz (US)
Now, at Telcel Mexico , they told, if I buy a phone in the US, it has to be an ATnT compatible phone, and it will work without a problem in Mexico,same frecuencies as AtnT.
Are those the frecuencies used by AtNT??
If the only 3G frequency your carrier supports is 850Mhz, then it doesn't matter what other frequencies the phone is capable of.
Look at the table in the HTC One variants thread, and compare the frequencies of that phone with what is listed for AT&T. And more importantly, what Telcel Mexico support.
What about 4G and Europe, are they high or low priority? The Asian variant supports 850Mhz 3G and has a good overlap with the European 3G and 4G frequencies, but not the US 4G frequencies. What do you consider more important?
