How to unlock 3g on a quadband Raphael.

I'm In India,
I got a Raphael this particular one :HTC Raphael
It has a Qualcomm® MSM7206A™ 528 MHz
with the latest stock radio : 1.13.25.24
And a custom ROM.
Now my problem is at the time i bought this there was no 3g in my country.
Now a few carriers provide 3g.
I can't access 3g.
I want to know if there is any way to access 3g by installing a PROGRAM or a ROM or a particular RADIO.
P.S: it doesn't matter if i can't make video calls(as no secondary camera) i would just like to access 3g network.
Please help needed and much appreciated.
PLEASE HELP
Thank you so much.
please help needed ( ihave searched all the fourms but haven't really found a solution, i have PMed many developers they don't respond. Please don't close this thread--> to mods. This is really important.

the raphael can handle 3g no problem. it's up to your service provider to give you access to 3g...

Try just going into the Comm Manager and enabling 3G and see if it connects.

My raphael is not unlocked or maybe doesn't have the chipset to recieve the 3g network please see my link !
I'm asking if there is any way that i can unlock the settings !
It is nothing to do with operator or comm manage.
Please understand the problem.
The problem is the chipset/processor not the Software or the operator
anyways thanks
PLease post if any solution...

When i first bought my TP, i used my old sim card (from my BA) which was only supporting 2G..so i had to go to the operator to ask for a new sim card that support 3G! once i got the new sim card i could get into 3G no problme....
check your sim card if it support 3G
also check the network setting on your phone (start->setting->phone->band and then make sure to select auto or WCDMA)
hope this helps

Hey GUys please GO TO THE LINK I PROVIDED In the first post all this is not the problem the probles is the 706A processor provided by HTC which doesn't allow the phone to recieve signals beyond the 1900 band and the 3g signals are at 2100 band range !
And most of the Raphaels which have 3g have the 701A processors not 706A
I was just wondering if some senior member / chef / developer / a friend could help me.......
And tell if flashing a radio are a program will help this situation
Trust me it has nothing to do with operator, SIM , Comm manager !
Thank you all !
Please help if anyone....

actually... 3g operates not only on the 2100 band but also the 1900 and 850 band. It is up to your provider to allow you to use 3g. When I went back to thailand, the phone company I used "locked" 3g and my phone would complain that i could not connect to 3g.. until I called the phone company and I went through a series of instructions that "unlocks" my number to allow 3g.
You need to do a little more research on your question before you go ahead and tell everyone they're wrong. Trust me, providers can prevent you from using 3g capabilities.
The radio only helps transmit the information. some work better than other, but they do not prevent you from using a specific radio. Processors also do not matter since it is more related to the processing speed of the phone, not its ability to handle networks.
check this link to see that the touchpro is indeed, 3g ready, all versions of it that I know of. http://www.gsmarena.com/htc_touch_pro-2413.php

Sir with all due respect and without being rude to you i have to tell you to READ THIS LINK BEFORE POSTING :HERE
And please note the network part and the part which says the processor :Qualcomm® MSM7206A™ 528 MHz :this processor is the processor which does not allow me to recieve the 3g signals.
And in my country my operator does not have 3g yet but would launch in december. I traveled to 3 countries in last 1 year and tried to connect 3g (with stock radio and rom and failed)
I respect you but i have to say you are "Wrong"
thank you
and please refer to the link.
And i have done all the research i could possibly do before posting a thread.
Thank you ( no offense meant)

ok. you are right. In this case, there is nothing you can do since it is the chipset itself. It is not meant to do 3g and it probably will not do 3g unless you go in and try to mess with the bios itself. That would most probably brick your phone. So to answer your question, no it's not possible unless you want to risk bricking your phone.
the only thing i can say is that it sucks that you bought the version that couldn't do 3g, but there is probably not a way to change that.

It looks like it can not do 3G at all. Interesting, I didn't know they made Raphaels without 3G. It probably doesn't have any hardware to do 3G, just like the european ones don't have the hardware to do 850MHz and 1900MHz 3G used in the U.S.

yeah. I thought all touch pro phones are 3g enabled. Well I would have to admittedly say that it really reeks to have a 3g capable phone forced at only 2g through hardware limitations.

guys 3g can be possible
if ppl here check this prior link http://www.gsmarena.com/htc_touch_pro-2413.php
it will show that the release date is june 08 so it means that the company at that time had 3g capabilities in the tp well i am from india mumbai and am using mtnl as a network provider well i had 3g enabled on my sim card 3g did not work on my tp but it did work on my friends nokia phone so the question of sim card not supporting 3g does not arise also asfaik it has something to do with the radio especially the protocol version which should end in something that is not 'G' so i want ppl who are reading this to post some of their radio of links which points to a radio ...

Hey do you also have the 706A procesoor ??
And guys it sucks that HTC dared to do this cheapstake thing !
Anyways my bad luck I'll change now only after 2 years so no 3g......
But on the optimistic side i love every other part of the phone specially the way flashing can be done like no other phone !
Its great !
3g would have been an icing on the cake though !
but HTC sucks with that !
Thank you all...

sorry francis. As I have realized later in this thread, based on the OP's phone spec, his/her phone is quite literally incapable of doing 3g because it does not have the hardware capability to utilize it.
sim cards, as far as i know does not do anything with which band you can use, it simply holds information like contact list and your phone number ID. Radio also does not matter as i have stated in an earlier post. Radios are like channels on a wireless router, it can send the same signals, it just depends on which channel works best with the majority of computers in the place.

just for your information even Francis has the same set of TP with the same processor (706A) and hence he has the smae problem/ bad luck !
And we both need the same solution ( IF ANY AT ALL.........)
Thank you.

yes i realized that I misread the post and misunderstood your original problem. But in this case it seems like a hardware limitation. something you can't solve with software changes. Although I'll have to admit that there is a chance that a bios flash might do something. but you will probably run a massive risk of bricking your phone permanently and I highly doubt it is worth the risk.
Hopefully one of the mods here would know if there is a way around this. good luck

A definitive answer to the UMTS quad band question

Hi,
I've read through plenty of threads (including that massive 350 post thread) on whether we have quadband UMTS in hardware or not? The answers there weren't very clear, so I went to the LG homepage, and they seem to have updated their brochure to mention only the AWS bands after a lot of complaints from our side. Some T-Mo reps state the hardware is present but the software isn't, while others completely say that there is no hardware at all.
After that I read through the service manual, and in that various pages there is only reference to the AWS band and Band 1. I've snipped a few screenies and uploaded it here - http://simkill.imgur.com/g2x
This confirms beyond all shadow of doubt that there is NO HARDWARE support for global UMTS bands.
Shame really, I didn't mind waiting it out till someone came up with an updated baseband.

I wouldn't call it definitive.

Well why not, I'd like to see more than just a statement, although my title may have been a bit sensationalist I'm almost certain about this.
I read through the manual, and although in many many places it says that those internals have *support for 900/1900*. But nowhere are proper working specifications/test results been mentioned for the other bands. If you have any information, now would be a very good time to share since I'm planning on returning this in favour of the O2X in two days.

Unfortunately I don't think anyone has that information. Only time will tell. I'm not ruling out the possibility because it isn't supported currently though. Something just strikes me as strange.
If AT&T 3G is a frequency you require then flip to the O2X.
Is there a radio for the O2x? Has anyone taken the phones apart to compare the chipsets?
Too many unknowns to be definitive. But your pressed against time so I understand.

I really liked the G2x, it was everything I wanted in a phone including HSPA+ but alas, it wasn't meant to be. I really want to be wrong on this to be honest.
Yeah, later on tonight I plan to search for service manuals for the O2X, and read through them as well.

Buying a phone in the USA for use in Europe

Hi there,
I will be visiting the USA this summer and since the swedish crown is fairly high compared to the dollar, the prices are really good compared to the swedish ones. I am thus considering buying a new phone there, and would like to know if, and then what, problems might arise that I need to look out for.
I realize I need to make sure it isn't locked to a carrier for obvious reasons. Are phones today sold with bands unique to different regions or are all bands included to make sure the calling works no matter where I am? Furthermore, will there be any issues with other connectivity, like 3g, 4g or wifi?
any input is much appreciated!

Quad band (also known as quad-band or quadband) literally means four bands. Having more than one frequency in one device is useful to enable roaming between different countries that peg the allowed transmission frequency at different values or to allow a better coverage in the same country.
If you are using your phone internationally and also do travel extensively in the USA, and you wish to be connected at all times with your work or your family, than you must buy a phone with this function. Otherwise, any phone will do just fine, even the really inexpensive ones...

Other than the quad band, nowthing else is needed? I believe I read somewhere that even wifi-connection could be different in different regions, how about that?
Anything else I need to consider?

If a phone has "Wi-Fi CERTIFIED" sticker it flawlessly works overall in the world. You must not have any concerns.

Ok, so as long as it's quad band, wifi certified and is not locked to a certain carrier nothing should be a problem? How hard would such a phone be to find in the USA?

[bounty][1BTC + 60USD] Add 700 1700 LTE Bands on n9005

Bounty for the first person to post a solution to add the 1700 700 LTE bands to the n9005.
Seeing as its believed to be hardware supported many of us are trying to unlock those frequencies for true international LTE.
Possible solutions proposed:
Flashable AWS modem for n9005
NVRAM dump with AWS config.
Bids** so far:
IamNoone: 1BTC
Nakedtime: 20USD
xaviero17: 40USD
**Feel free to bid USD, I just happen to find BTC more appealing.
current BTC Trade value: http://bitcoinity.org/markets
Heres hoping we get some workable solutions. Even if they're easy.

If the hardware supports, you would simply need to import (and maybe modify slightly) the QCN file from an N900W8 variant and upload to your 9005 device.

QCN contains IMEI, must also be edited to remove imei.
Besides, has one been dumped from a W8?
Someone feel free to dump...

Would this mean we could use the 9005 on at&t LTE and 3g network?

N9005 already operates on ATT HSDPA and UMTS.
This is for ATT LTE.

I would love to see lte band 18 and 19 supported. Those are the japanese 800Mhz bands, that practically no phone except the crippled japanese provider models support.
Anyway, modifying the radio to send on those (or any not certified) bands would very likely be illegal in nearly any jurisdiction, wouldn't it?

In a case like this it would be much more likely for it to be a hardware issue stopping you. I don't think that a band like that, which is not supported on any Snapdragon note 3 (or am I wrong?) Would be possible to just change by software. I do know that if the antenna isn't designed for the frequency the signal would suck and you would likely also get signal reflections into the phones output amps, among other problems. And that is assuming you child even get the chip to try to transmit on those bands....which I also don't think you could do

Not are not exactly wrong, but the bands 18 and 19 are very close to bands 5 and 6. Both are supported as far as I can tell, although 6 is only for UTMS. But that means that the power amps and antenna tuning should be there. Also, qualcomm advertises this "rf360 solution" which is supposed to support more or less all bands between 700 and 2700MHz. No idea, whether is is in the note3 though.
So you see, I did give this some thought.

We might want to make a separate Bounty for this kind of thing. Such as unlocking ALL frequencies supported by the Snapdragon.

I prefer to make the assumption that people have honorable intentions. For several people, they're just trying to get LTE on AT&T.
There's no good reason that anyone would want to use illegal frequencies, since such frequencies would likely not give them cell service anyway.

I think what he means (judging from the knowledge he would seem to have on the topic) frequencies that are not certified for use in a given jurisdiction, not "illegal"frequencies in some other way. In the US fir example, if you use a device that transmits on any frequency that your device has not specifically been passed for by the fcc (and above a maximum power limit which is rather low, from what I recall) then you are breaking federal fcc regulation with respect to creating possible interference, transmitting radio signals on a band your device want created for etc. It can get you into big trouble. Having said that, unlocking your phone in the states is legal to, but no one is ever going to find out. Same thing with the frequency thing, they have those laws so that a) when someone creates interference they can stop/prosecute them and b) so they can stop people importing devices for sale that are not certified.
Having said that, if it is not a frequency that is explicitly supported by the hardware then but that is simply close to a supported one, it would require more than just a hack. It would require reverse engineering the Qualcomm code and then writing your own hardware interface software etc, that is assuming that the bands are close enough that the amps and antenna would work, then you would have to hack the rest of the firmware to actually utilize these new bands and actually talk to your other new software.
In short, it is highly unlikely that it would be possible, at least given the time and resources that most people would spend on dev work (which I understand is a lot but this is a much bigger deal than dev work on open source code) and also Qualcomm probably would not look to kindly on us reverse engineering their stuff. Also, it is quite possible that the hardware commands simply would not exist for the software to ask the hardware to do this. I am not familiar enough with the Qualcomm hardware nor mobile hardware in this way, as I've never programmed or dine dev work on android phones(single dad now with not enough time as it is) so I can't say for sure here but I have a hunch that the hardware simply was created to offer functionality on certain bands and that is all it would offer. If it was unsupported in software but supported in hardware, that's one thing, but unsupported in hardware pretty much means you're sol in my opinion

That's exactly what I meant. If it was just a matter of editing a config file, it would be unlikely to cause any interference. I do assume, that the original radio firmware is well-behaved and doesn't start sending on a given frequency unless it picks up a cell tower there first. However, regulators have been known to look unkindly at uncertified devices, especially if you cause interference. And you most certainly void your certification if you modify the radio.
Anyway, I did unpack the radio firmware and looked around in it with a hex editor a bit, hoping for a lucky find of the needle in the haystack, so to say. What I found was not very encouraging. It's a batch of binary files. Some looking like bootloaders, others looking like L4 realtime kernels. There also seems to be a qurt kernel, whatever that is. Maybe some kind of Qualcomm realtime os implementation. Also dsp firmware or some such. Then I found some strings that might be part of digital signatures. I did some googling on suggestive strings I found, but if there is any documentation on that stuff, then Qualcomm keeps it secret (or I am too stupid to find it).
There was no such thing as "SupportLTEon700MHz=false" or something like that. Not that I expected anything like that.
So unless there is an insider somewhere willing to violate all kinds of NDAs and contracts, it is unlikely that this will happen, I think.

Both of you are making this more complicated than it probably needs to be.
For one, the phones that DO support 700 and 1700 use the same chipset. This is something that was done on the Note 2. A simple config change unlocked those frequencies. I believe we'd only need to repeat the concept for the Note 3. In other words, all we need is for someone familiar with the process to take on the job.
The Snapdragon 800 (N9005's chipset) does accept the LTE_B17 line of flags. (LTE band 17). It's already in the hardware, we just need to turn it on.
This bounty explicitly states for 700 and 1700 LTE bands, which the chipset DOES support at least 1 of those bands. This isn't about the Japanese bands, that was brought up by someone else and isn't what this topic is about. Please make a separate bounty for that feature so that people aren't confused about THIS topic.

Ahh I would love to see this come out for the Note 3 a nice simple way to pick up the extra bands our hardware is capable of.

Me and another member got relatively far with this but was not able to flash the N900W8 modem onto an N9005 because the boot loader is locked. We were going to try a few other things before I gave up and just bought an N900W8 for cheaper than what I paid for the N9005.
The QCN file was edited to match that of an N900W8 with respect to a few entries in the LTE BC CONFIG. Unfortunately just changing it resulted in no service. We then proceeded to change the WCDMA band configuration to match, but like members of the S3, this is apparently overwritten some how by the device on boot. You need to reboot the phone for the modified QCN to take effect, so basically it did nothing.
Whatever solution you guys come up with its probably a matter of a complete modem and QCN file then reboot to make it happen.
I tried to write a custom update.zip file that overwrote the two partitions containing the modem.bin and NON-HLOS.bin without success.
Rogers parameter 6828:
https://docs.google.com/file/d/0B9KfOSKSSjgdSEE2Z043U09JTGc/edit?usp=sharing
LTE BC CONFIG MENTION:
http://forum.xda-developers.com/showpost.php?p=33234706&postcount=43

In regards to an update.zip. You must execute the flash after following the same sequence of steps as when flashing with odin. (eg remove battery, put battery in, hold vol down and home, plug in USB cable, then odin will come up) Except instead of vol down, use vol up. Something about this sequence unlocks the ability to flash modems (in odin, recovery and root). (if you don't do it, writes to the mmc will timeout)
While you /can/ flash modems for W8 and T on the N9005, they will fail to boot, apparently enforced by the PBL (the lowest level bootloader on the device).
Changing individual parameters in NVRAM may not take effect for a number of reasons;
1) There are two partitions (MODEM*1 and MODEM*2) that seem to contain NVRAM parameters, but are not directly part of EFS. They look like backups of critical parts of NVRAM, i suspect during the boot sequence, these BINs push NVRAM parameters into EFS, overwriting any changes. I was unable to trivially decipher the contents, but i didn't put a lot of effort into it.
2) Some kind of failsafe similar to the Modem flashing problem. (modem wont stick! maybe NVRAM wont either!)
3) Modem itself may set certain parameters in NVRAM. Only way to test this i think would be to try changing IMEI in NVRAM, and see if it reverts back on reboot. As the modem doesn't pertain to your IMEI, it would never correct it if it was incorrect.
Personally i think #2 is the case, and will try to enable change via cold boot method.
I have successfully changed the modem partition to contain arbitrary data, as long as the binaries are untouched. As soon as they are modified (even eg. changing the name of the baseband), they will not operate. So they are probably protected by signature or hash.

Got NV#06828 to stick as 5B0001. It was originally D50008.
It however, does not enable the necessary bands, it would appear. The value is persisting across reboots, so indeed it has been changed permanently.
I suspect NV#01877 needs modified as well. But i've been unsuccessful in getting it to stick.
I'm attempting to change 040002 to 060000 in item 1877.
The fact that i was able to write NV#06828 suggests that 01877 is likely changeable as well. Still haven't figure out what conditions are allowing writes to persist. Luck of the draw seems to be what makes it work.

Bumping this

I'll pledge $20 for 700MHz AT&T band

Does Mi4 have LTE now?

Planning to buy a new Mi4 from kijiji. Wondering whether it supports LTE bands in Canada? I;'m with telus

Short answer. No, not yet.

OK.Thanks
Is this a software issue or the LTE version is a different hardware in the future? In other words, if i buy the mi4 now, will i be able to get LTE when its available?

Sadly it seems to be a hardware limitation. Xiaomi was smart when they made the phone and only have it what it needed unlike some companies that overlook the small things and pay in the end.

yes it does not. as no opomart and other sites are selling FDD-LTE version which 1700/2100 works perfect with ATT / T-Mobile in US

4G:FDD-LTE 1800(B3)/2100(B1)MHz

This may seem far fetched but I'll ask anyway. Is there a way to change the hardware frequencies set within the phone to match the connectivity frequencies that's in your area?

In theory, the chip should support them. It would be a matter of writing the specific band values into your phones memory (NV). However, this pre-supposes that the phone could be modified on that level to begin with, which is doubtful.
You would need:
Unlock/root
Custom rom
Custom kernel
QPST (for editing)
QXDM (write enabling)
access to switch usb diagnostic mode
The majority of the work would be getting around MIUI and Qualcomm's restrictions they implement in their code. While not impossible, as you can see, the changes required aren't necessarily for the faint of heart. I suppose one upside would be the phone doesn't cost an arm and a leg, so if you wound up with a brick, you might have an easier time bouncing back from the loss.

Thanks for the insight bro. You really broke down into detail what was needed to be done. Was scrolling around and found this thread http://forum.xda-developers.com/showthread.php?t=2871269. Would like your opinion on it. It's for unlocking LTE as well.

I think they released the LTE-FDD version , seach for it!

already got one with LTE...its out already

Hi, I don't know how helpful this is for you but I have bought two from China for myself and my wife. Although I have not tried on the MIUI OS, I have flashed AOSP on to both phones and they both work at least on O2 and EE. I am receive 4G on my EE Mi4, however my wife does not have a 4G sim so can not confirm hers but she does receive 3G signals.
O2s 4G sim did not receive 4G signals on my Mi4 though (reason for me switching)
Hope this helps you

Only bands 1, 3, 41
