Hello fellow enthusiasts,
I have a burning question that I need answered, and can't seem to find the info anywhere online. I was thinking about s off'ing my m8 dual sim and flashing the regular m8 radio, as I only use one sim. My provider has lte, and i have an lte plan, but the radio range is 800mhtz, where the phones lte radio is 1800. The question therein is, would flashing a non dual sim radio to a dual sim device brick it, or work?
I've flashed radios before on many different phones, just not a dual sim variant.....
Thanks for the help!!
They are different hardware, and different radios.
I'd say a brick is probable. Failure is almost certain.

Hi there,
I'm totally confused as to what I need to do to get my Touch Pro 2 (currently activated on Boost CDMA) to work abroad, specifically Canada.
It is flashed with Energy ROM, Reference version.
Do I need to do a Radio flash? Do I need to tweak some settings? Both? Neither?
I'm going to be in Canada for 3 weeks and plan to use either Rogers or Fido's GSM Pay as You Go (already have the SIM cards), or Telus's CDMA Pay as You Go.
I've read the FAQs and generally understand that this is possible -- just not clear the route.
Thanks,
Simmy
The biggest problem with Canada is our carriers don't want people coming in and using their networks without paying for it, and that usually means your first born here.
The hardware problem is, the TP2 will not work on the frequencies in Canada that Telus has used for the HSPA / 4G network. And using the current CDMA network is not possible either because Telus and Bell will not allow you to put branded phones from other companies on the old network and CDMA systems don't use SIM cards. So if your planning on bringing the TP2 up here I think you may be out of luck.
I took the TP2 to Ireland and was able to use the frequencies there on the O2 network, but to do that I had to unlock the phone and as i have the "world edition" with the SIM card slot once unlocked it worked over there no issue, and returned working over here with no SIM card in it. But again this is a frequency issue and telus tells us it won't work.
Now if when you get here, and you plug a sim card in and it does work, please share, because it means we can manually add frequencies and hook to both the old and new network. And some of us with the original unlimited data contracts (no 10 gig cap) would be really happy to know this.
As for Rogers, i can't tell you. I don't know if they have ever had the TP2 and have no clue what frequency they are using for their phones, though i'm sure it's similar.
Flashing the radio does nothing to add radios or affect your ability to connect to the network while abroad. Its usually just done to improve reception and/or battery life.
You will need your phone SIM unlocked. Then, as the post above suggests, either putting in the SIM works, or it doesn't.
Thanks to both of you for your reply.
So the TP2 won't work on any Canadian CDMA networks, but since it also has GSM, if I stick a Rogers or Fido SIM card in it, it *may* work. In fact, I believe it *should* work. I'll let you guys know how it goes.
And thanks for answering my question re: radio ROMs, Redpoint -- that's what I thought, but was still confused about.
So, with respect to unlocking, is the Olipro page that charges 11 pounds / 14 euros / $20 my best/cheapest option? (unfortunately, i can't link to it here because I'm a new member)
Thank muchly,
Simmy
The device should have no trouble connecting to a normal GSM network in Canada. The Canadian GSM networks use the GSM-1900 and GSM-850 bands. The CDMA Rhodiums use a quad band frequency that spans all of 850/900/1800/1900 MHz channels. You should have no problems in Canada. Enjoy your trip.
You do not need to flash a new radio to have it work in Canada.
Forgive a relative noob, but are Desire GSM and Desire CDMA ROMs different? I have an Incredible but am trying to index Desire ROMs for http://www.heylisten.org/ROMs/android and don't know whether to categorize them differently. The Inc, of course, along with almost everything else, has only one version, so there's no question there, but I'm stumped on the Desire. I don't want to confuse anyone, but I don't want to force users to reflash unnecessarily. Thanks in advance for answers!
CDMA and GSM are different types of mobile networks. Because of their different way of functioning, phones need have specific hardware and drivers to be able to use the network. That said, a CDMA phone will not function using a GSM network and vice-versa. Usually, networks are GSM (all over Europe, and I don't think there is any country in the world which has only CDMA networks). The only CDMA's I know of are USA's Sprint and Verizon, though I don't know much about Asia and Canada.
The ROM's are different when it comes to the radio, and a bad radio WILL brick the device, so you should definitelly state which one are for CDMA and which for GSM (there's a chatch here: since a lot of the Disire's are GSM, you could specify all ROM's are for GSM, unless stated they're for CDMA).
Hi all,
I've recently moved to China and taken my Desire with me. I had assumed I could just unlock it and use a chinese sim but it doesnt seem to be working. From what i've read on various sites it seems China telecom (who are my new provider) use CDMA(?) and Evo-do(?). I'm not going to pretend to understand what these terms mean.
Does anyone know if there is a rom i can flash which will allow me to use the desire on this network? Failing that I do have a chinese lenovo a68e but all of the sites i've found for it so far are in chinese so if anyone can point me in the direction of a custom rom for it (english please ) which i can use i would also be grateful but i would much prefer to get my desire working.
Any help or advice you could give is very much appreciated.
Sorry mate, I'm guessing you have a GSM device (it have a sim card in it). GSM and CDMA are two completely different technologys, they have different hardware in them, that's why CDMA users brick there phones if they flash a GSM ROM. I don't think there is a way to just change GSM into CDMA by flashing a Rom.

Thanks for the quick reply
My new phone has a sim card just like a uk one. I'll be honest and say I don't know much about any of this stuff but i've found good advice on this site and used roms and things found here before.
Are there CDMA sim cards and GSM sim cards?
It not problem in sim cards CDMA and GSM are network technologies,you have to buy CDMA phone(for example CDMA htc Desire).No ROM can help you.Here's more on CDMA and GSM.(link)
If you have a GSM device, China Mobile shall you go.
no, the difference is in hardware level, u can't do nothing
My brother in-law just got a M8 Dual Sim (European). but for some reason he is not getting LTE connection.
I tried the same sim on a different phone and got LTE instantly. What is going on?
Should I unlock the bootloader and flash a different radio or try another rom?
please advise
It can't do the most common frequency: 800Mhz
1800Mhz and 2600Mhz work fine, but you mostly just get them in big citys.
How to know which LTE band?
Hi!
I know that this has been talked before, but I could not find anything that works.
I have bought a HTC M8 dual sim in switzerland. Back in Argentina, I tried to make 4G work, and, of course, it doesn't.
I have read that there is some chance to change the band, by the qualcomm.
so.. how do I know which band(S) does my phone have?
Thanks in advance!
I use "LTE Discovery" App. Available on the Play Store.

According to this webpage, it supports LTE bands 3, 7, 8 and 20. And according to list of LTE bands by country on Wiki, Argentina uses LTE band 4. So it makes sense that you don't have LTE.
While radios are typically interchangeable among "regular" GSM M8 versions (s-off required to flash radios); this is not true for the Dual SIM. So while you are correct that band support is software based on the Snapdragon 801, the normal method to change bands is to flash another carrier version's radio. I don't think you have another version's radio to flash. Some folks have modified the the NV values on the CDMA M8 to change band support. But to my knowledge, nobody has gotten this to work on non-CDMA versions of the M8 (the changes just revert themselves after reboot).
I suspect you are out of luck. This is really something you should have researched before buying the phone.

I kind of did. This is an fantastic mobile, besides the LTE detail; and by buying it in europe I've spent less than half of its price in Arg. pitifully.. I need the dual SIM. So, still a win win.
I will try to modify the NV values with QXDM... maybe i still have some luck left.
thanks =D
