Best Rom/Radio for Dual CDMA (Sprint) / Domestic GSM (AT&T) usage

Im looking to flash a custom rom to a Sprint HTC Touch Pro 2 for the sole intention of getting rid of my work phone (AT&T Blackberry). What is the best ROM (and easiest to switch between radios) to do something like this?
Thanks for any tips!

So far as I know you cannot flash a GSM ROM to a CDMA phone. It will not work.

The CDMA touch pro 2 is also a "world phone" so it has a built in GSM radio. The key is unlocking it for domestic GSM carriers. There are some unlockers to do this, but I am assuming there are various different radios and ROMs you can use that may make this work better or be easier to use.

I am aware of the "world phone" capabilities, and I stand by my statement. You will brick your CDMA phone if you flash a GSM ROM. You need to flash a CDMA ROM.
I believe that it is possible to "un-brick" back to CDMA, although so far as I know no one has "un-bricked" a GSM phone that was accidentally flashed with CDMA.

for better results... aka answers.
i suggest asking this question here --> linky.
because primarily your phone is CDMA,
therefore a CDMA ROM would be needed/required.
i also suggest a read of this --> linky.
it is very informative.
and should help a lot with answering your questions.
hope that helps.

As a CDMA/GSM phone we have the capability to use a GSM sim card, but we can only use tools that were specifically built for CDMA, including ROMs/radios. Flashing a GSM rom/radio will seriously hurt your phone, possibly rendering it unusable.
To unlock for a GSM carrier in the continental US, you will first need to SIM unlock, either through calling your carrier and requesting a SIM unlock or using the olinex SIM unlocker found in the CDMA forums: http://forum.xda-developers.com/forumdisplay.php?f=517
There are a couple guides to getting the tp2 working on various carriers.

Wellllll... Where are the guides

Please some help,
I have read and reand and dont find the answer.
i have a world phone, i just to know if there are custom ROMs for them, i use it mainly on GSM but i would not like to lose the CDMA option.
My device is a sprint TP2, i am using it in Mexico, with telcel GSM. I Just want a custom ROM for it, please Help!

Compatibility to different network Issues..?

Hi XDA,
I am currently on a T-mobile contract, but I will move to a different country for business purposes.
I know how to do the device unlock (thanks to youtube), but I was just thinking of different issues that
might come across when using different GSM network.
my device is rooted, running custom rom with T-mobile radio.
my questions are:
1. even if i unlock my device, shouldnt i flash a different rom that is compatible to other networks? (different radio too?)
2. could i use the roms and radios that are used in international version?
if the process is more complicated than I am thinking, could someone light me up?
Thanks in advance.

Never flash anything from an international model as you will brick your device.

HTC One m8 variants

Hi guys,
Planning to buy the m8 and root it. But should I be specific on the variants?
Im not from the US (The Philippines) so Most likely not gonna get atnt, sprint etc.
So my options are:
The international model
Emea (a friend of mine is selling his but it was bought in riyad, KSA)
Or the asian version (s801 2.5ghz)
Do they have like different model nos.? Different ruus / rom versions etc?
Had a bad experience when i bought a phone (m7 sprint wls) before, since im not from the us. Had limited roms available compared to the international version
Your input would really help

I would agree that you should not get a US variant. For one thing, they will be SIM locked. Another thing, the Sprint and Verizon versions are CDMA. Different software, and possibly different hardware (although its been discussed here, and not clear - but I would err on the side of caution and assume the hardware is different). So if your area does not use CDMA I would stay away from those variants.
All GSM versions, be aware that they can all be converted to another carrier variant once bootloader unlocked and S-off. So as long as you avoid the CDMA versions, you are good for ROMs.
I would suggest the version that supports your local 3G and LTE bands out of the box. But again, as long as you are willing to s-off the phone, you can change that in software. So if that is the case, I would just go with the best deal.
From what I understand, the Asian version is the same as any other GSM version, just with a slight overclock.

Well if you do go with a us carrier Verizon has the best coverage and thier phones are :not: sim locked. You can use them with any carrier anywhere. My second choice would be t-mobile

The OP is from the Philippines. They aren't going to use a US carrier.
I would advise against CDMA variants for the reasons already mentioned.

Thanks guys, I just want to be clear, so if I use a Rom or RUU on a GSM variant, as long as Im'm on S-Off / Unlocked Bootloader and/ or on SuperCID. I could use any Rom ./ RUU from different GSM variants (I checked the rooting guide for the M8 and is similar to the M7, so as far as unlocking the bootloader / root that I have an idea).
Do they have different RUUs at all??

Yes.
Aside from the CDMA RUUs, which I wouldn't try on a GSM version unless you read definitive advice elsewhere that its ok.

Only US versions have RUU, that I know of.

Yes you're right.
I thought all has ruus on it. But with supercid i could use any nandroid backup right? As long as its gsm
I think I will go for the Asian version (wwe right? Cause it has a higher clockspeed and updated s801) And go supercid and use international (gsm) roms. Will that work?

WWE just means "world wide English". I think it refers to the Euro version.

HTC One M8 of Choice?

I am looking to buy an HTC One M8, which would the community recommend? I am on AT&T but I love to root, and install CM, and other ROMS to any phone I own. Which Variant would be best for me? Or are they all supported under CM and custom recoveries? Thanks!
Also if anyone has one on the cheap let me know

I was thinking about that, the problem is I always end up getting a phone a generation behind the newest thing! Lol m9 looks amazing though!!

For the most part, I'd say whatever variant you can get for a good price. All the M8's (known as "GSM M8") are the same hardware internally aside from the following exceptions:
1) Dual SIM M8
2) Verizon/Sprint variants. These include CDMA radio, so different hardware. No benefit for you on AT&T, and less selection of ROMs.
3) Taiwan variant. Hardware is the same, but its overclocked out of the box. Some software from the other M8 versions won't work on this variant (including radios).
Aside from the variants above, all the M8 versions are essentially the same hardware, with minor differences of exterior color availability, and carrier logos on the back of some. Once bootloader is unlocked (and preferably s-off) you can flash CM to any of the versions.
One thing to note, AFAIK any M8 that has hboot 3.19 cannot be s-off by sunshine (and that is the only s-off method). Band compatibility for the various carriers/regions is software based on the M8. However, if you need to flash the radio to change band compatibility on a non-AT&T M8 variant, you will need s-off to do so. So unless you have a way of knowing what hboot is on the version you are buying, I tend to say that you might want to choose either the AT&T version or Dev Edition, to guarantee band compatibility on AT&T's network. Both of which fully support AT&T bands out of the box.

Right so, Verizon M8 wouldn't work on AT&T? That sucks. I knew Sprint wouldn't but Verizon is nearly compatible with AT&T by now, so thats sad lol
The best price is the Sprint variant, but thats because sprint phones do not have high resell value at all. People hate to deal with them completely and that solely makes the value go down...
I have not looked at the other variants but I will check them out! Thank you! I repaired a One today, It was a lot of work, but nearly any HTC Phone never looks or feels the same after a screen repair, because of that uni body.

I have a question. Does T-Mo work with WWE firmware. I'm unsure of this, and have never looked it up. I know that AT&T versions are compatible with 401 firmware. Is T-Mo the same?

but you could check with the seller if it is S-OFF already (as you can be S-OFF with 3.19 if it was already done) if thats what you are going to do anyway.

Verizon variant will work on AT&T GSM and HSPA network (in addition to being SIM-unlocked out of the box); however, it doesn't have all the LTE bands to work on AT&T in all regions. And while the "GSM" variants can have radio software flashed to change band compatibility, you can't do this on the "CDMA" variants (at least you can't flash a GSM radio on a CDMA variant to open up all the needed LTE bands).
Similar situation on Sprint version. Except I think the Sprint comes SIM locked out of the box (you will need to get it SIM unlocked). And also the LTE bands are different from the Verizon version, but still not all the bands needed to work on AT&T in all regions.
My point in highlighting the hardware difference (CDMA versus GSM variants) is not only are the radio basebands not interchangeable (as mentioned) but neither are the ROMs. For the CDMA versions, you should only flash ROMs that specify that version is supported. The GSM versions can flash any of the GSM ROMs, and there is a much wider selection.
Again, there isn't a benefit to either of the CDMA variants (for use on AT&T), and several critical downsides, so I generally don't recommend them to basically any user that isn't on the specific carrier (Verizon or Sprint).

True, if the device is being sold second hand, you can (and should) always check to see if its already s-off.

Aside from the exceptions previously listed, all GSM M8's are the same hardware, and firmware should be interchangeable (with s-off). T-Mobile version should be able to flash WWE firmware. Although, if you want to be prudent, you can check and confirm to see if any T-Mobile owners have done so successfully.

best radio for telus/koodo

Hi just purchased a used Verizon m8 and i did the s-off and installed a few custom ROMs but I get dropped and weak signal every now and then. Just wondering what the best radio to use for telus/koodo. Thanks.
I am on cm 12.1 great ROM. My radio 1.12.23.1211

You did no research. You shouldn't have bought that phone.
Verizon is cdma. Telus is GSM.
I'm on Telus as well using WWE/International firmware.

Telus/koodo and bell in Canada are also a CDMA/gsm company. This phone should have no problems with telus/koodo. How is the wwe firmware do you see a difference in signal. Is your phone root and are you using any custom ROMs.

Click this link, and scroll down to "So can I use my Android device on other networks?" (Actually you should read the whole article. It's quite informative.)
I'll quote the second paragraph from there for you here:
First off, if you have a CDMA handset (the lack of a SIM card is a sure fire indicator) from Bell/Virgin or TELUS/Koodo (that isn't a world phone) or from the US (Sprint/Verizon), it is impossible to use the phone on a Canadian network other than the one it came from as Bell and TELUS does not allow the import CDMA devices from outside their network.
I'll say it again, you didn't do proper research. If you would have bought a GSM phone, you wouldn't be having this issue.
The link also has a chart that shows the compatible carriers for the different bands/frequencies that are available.
