Basic state-of-the-cdma? - Samsung Galaxy Nexus

Hey,
had to go back to stock after some bootloops this morning and read the CDMA/LTE version listed on Google's dev page for Toro are listed as "archived"??? So what, they're not developing Toro anymore? And to that effect I'm confused, can I flash a GSM image onto this particular phone or are they of different hardware?
Really what I'm concerned with is Google no longer 'supporting' Toro? And if not, what does AOSP mean and are we in the territory where I should start looking into community developed ROMs for more bleeding edge support (in which case anybody have any stable suggestions? I just want something that works and works to the greatest extent of the hardware at hand.)
Thanks!

They are supporting the Toro just fine. They don't have access to some CDMA specific blobs, so it isn't "true" open source is my understanding. It is on the latest update the GSM version is.
You cannot flash GSM software on the CDMA/LTE version.

No kidding? I didn't know CDMA was so proprietary...so GSM/CDMA software AND hardware is different? Thanks!

Apparently some parts that Verizon uses are proprietary yes. The software is fundamentally the same, they just differ in how they talk to the RIL since GSM/CDMA use different hardware for radios.
I could be wrong, but CDMA/GSM are basically the same stock software but differ in radios.

Running Android on a CDMA Rhodium

I have a CDMA Rhodium (Sprint version) that is unlocked so I can use it on AT&T. I want to put Android on it, however when I have tried in the past it wouldn't work because the GSM version wouldn't work on my phone and the CDMA version can't use the GSM signal. Is there anyway to use Android on my phone in this situation? Thanks in advance!

force_cdma=0 in your startup.txt, should work.
You can't run both radios at the same time, but GSM-only should work for you.

I thought simply unlocking the phone didn't help in getting American GSM signals, because the phone is set up to only look for Worldwide GSM frequencies which are different from American? It has the capabilities to run American GSM signals, but I thought there needed to be further modification besides just unlocking the phone. I know the actual frequencies have to be flashed to the phone in WM, but I was unsure on whether these frequencies are built into the XDAndroid build?

Frequency support is in the radio itself - you can't flash the capability. If what you say is true, then he may not get 3G service, but he'll at least be able to make/receive calls and txts. Internet should work, but be painfully slow.
I'm not sure what frequencies the RHOD supports, but AFAIK it's a lot - Sprint and Verizon sell the TP2 as a 'world phone' - and usually phones branded with that moniker have a wide range of frequency support - again, built into the radio. Has nothing to do with the software running on the phone. If the frequency is supported in WinMo, it'll be supported in Android.

I agree with you that it is built into the radio. What I was saying is that simply unlocking the phone in Windows Mobile does not "make active" the American frequencies because the programming is such that Sprint and Verizon make sure the software explicitly either blocks or makes sure it can not use those frequencies.
It could be that XDandroid does not have those limitations in the builds and can use whatever frequency you want to. I don't know how much XDandroid depends on the settings etc... of windows mobile to run though. It could be you might have to get rid of that issue in WM before Android will properly be able to use AT&T frequencies. I don't know which is true, because I am not planning to try to use AT&T on my phone, thus I don't care to explore it! I was just bringing up that possibility just in case the guy puts force_cdma=0 and it still doesn't work for him.

No worries. If that's the case, I'd like to know if it works in WinMo. Because if it works in WinMo and not Android, then we're missing something in Android. AFAIK we're not missing anything that's at the core like that, but who knows.
i always thought you had to unlock (http://rhodium.htc-unlocks.com/) AND flash a custom rom for it to work on gsm att/t-mo usa. i guess if it works in winmo, theoretically it should work in android w/ force_cdma = 0. naturally you'd only get 2G data, but ehhhhhhh..
I'm assuming when you say to use the force_CDMA=0 in my startup.txt file, you mean for the CDMA version of Android, correct? Or should I use the GSM version?

That's the beauty - there isn't a different CDMA/GSM version - every build supports both, simply by changing that force_cdma value in the startup.txt...

In order to operate on the domestic gsm network, you will need to Security Unlock, then flash a patched radio, then use a T-Mobile or AT&T SIM card. You will only have Edge data and not 3G.

[Q] RHOD400 ROM without Lockstream available?

I would like to try a ROM that doesn't have Lockstream built in, but I'm far too nooby to build one at this point. Does anyone have one posted for the Rhod400 platform (gsm)?

I don't know of any offhand, but RHOD400 is CDMA. Even if you might be using it with a SIM card, the device only functions with CDMA ROMs. I would suggest inquiring over at PPC Geeks. They typically deal more with CDMA than XDA. XDA has always been more focused on GSM.
RHOD400 GSM ROM without Lockstream available?
I have the GSM Touch Pro 2 from sprint and want to try a ROM without Lockstream drm installed. Has anyone built one already?
As I mentioned before, there isn't much CDMA development here on XDA. PPC Geeks website would be a better place to make this request. Make sure you use a CDMA ROM and not a GSM ROM. A GSM ROM on a CDMA device will brick it. It doesn't matter if you use a SIM card or not. The RHOD400 is considered CDMA.
Again, it doesn't matter if you use a SIM. The RHOD400 uses only CDMA ROMs. A GSM ROM will brick it.

[Q] ROMs from general forum vs. variant specific forum

I just got my T-Mobile variant m8 and had been sticking to the rather limited rom selection in my variants forum, but I discovered the general HTC One_m8 forum had tons of roms that supported GSM and CDMA phones. I'm feeling a bit confused, since any phone I've had previously never had been on multiple carriers. If a rom in the general android development section says it supports gsm variants ( using my brain when selecting, of course), will I be able to just change APNs to make it work with my network?
Apologies for noobiness, I'm just finding the world of roms again after my last phone had none.

Its not a stupid question, by any means. And the answer is not simple either.
Any ROM intended for GSM versions of the M8 should be safe to flash, and will for the most part work (and if fact may work perfectly). The hardware for all GSM versions is essentially identical aside from cosmetic differences.
However, some folks have gotten slower data speeds on ROMs not intended for their carrier. In particular, I've seen this mentioned by some folks using "international" based ROMs on the AT&T version. Your mileage may vary, and it might not be an issue for you. I don't want to discourage you from using any particular ROMs; but just want you to be aware.
Flashing the most recent radio for your carrier may or may not help, and is probably the smart move. s-off required to flash a radio manually, alternately can be installed by official OTA or RUU, and your phone may already be up to date.
In any case, stay away from ROMs intended for the CDMA versions of the M8 (Verizon, Sprint) as the hardware is actually different, and I've seen folks brick from accidentally flashing things meant for the wrong hardware version M8 (CDMA vs. GSM).

what the different between the HTC's

hii guys ,,
im going to buy the HTC m8 next week
i'v seen many type of version of the phone
like AT&A , Verizone , Sprint , Google Edition
so anyone can tell whats the different between them if there any !!
thank you
I believe the hardware is the same on all M8 variants (apart from the dual SIM ones) so all the differences lie in the software side.
AT&T, Verizon and Sprint will have a few differences to each other due to the bloatware they decide to add in.
The Google Play Edition (GPE) is running vanilla android rather than Sense (the same as Nexus devices). As they're Google devices, they'll get updates quicker than the other M8 variants (just slower than Nexus).
There's the developer edition which runs Sense but comes with an unlocked bootloader and will get updates quicker than the other Sense M8's, but not as quick as the GPE.
Then finally there's the Windows M8. This is simply running Windows 8.1 (I think) instead of Android.
It would help to know what region you are located in.
Some of the US carriers (Verizon, AT&T) have their logo on the phone, so you might not like that. And there is some difference in the colors available (for instance Verizon has red, Sprint Harmon Kardon edition has black back and sides with gold front). Other than those minor cosmetic differences, the hardware is identical, from what I understand.
Band compatibility is different on each carrier version, but is software based and can be changed by installing the proper radio (S-off required, which will probably also require sunshine s-off, which costs $25 US).
And as mentioned, the only other difference is the stock ROM, which for US carriers will have their own carrier branding and (tons of ) bloatware. Again, easily changed with unlocked bootloader or S-off.

Software wise theres carrier bloatware on each device. But hardware wise the Verizon / Sprint ones have an added CDMA chipset and from what ive read they are different from the GSM units hardware wise.
Blowing a GSM rom into a CDMA unit will brick it, or so ive read.

I thought and had heard the same as well (hardware difference between CDMA and GSM M8's). But several folks here have strongly claimed otherwise, that the radio difference is still in software; and that all M8's are the same hardware-wise aside from the dual SIM M8. So I'm not really sure what to believe.
That being said, the OP should probably get the version offered by their carrier, or intended for their region. Even if it can be "converted" by software, it just makes for less steps and less hassle. Unless there is some strong reason to do otherwise, like a much lower price.

I'm not too sure about this either. I've seen a lot of people saying they have the same hardware and seen a lot of people saying CDMA have different hardware.

And I haven't actually seen any definitive evidence for either case.
Looking at specs, both (GSM and CDMA versions) use the same chipset (Qualcomm MSM8974AB). I would think if there was a difference due to CDMA, it would have a different chipset number. But that's just a guess.
OP should stick to the version that matches their carrier (GSM versus CDMA) to be safe.

I actually thought the most "obvious" difference in hardware was the actual circuitry itself. They use similar components etc but the way it's "wired" is a bit different, but I don't recall where I got that info from

It would be great if you could link the source, it would settle this debate.
So you mean the copper trace/tracks between components on the board are different? I would assume that some of components and/or the layout is also different, otherwise why have different trace paths?
The following teardown shows the layouts of the Verizon PCBs, but I can't find similar into for the GSM version to compare it to:

Anandtech actually has a great write-up on the differences between the various models.

Specifically, the chart on the supported bands is useful.
Thanks for the help guys
I think all the versions supported here with operator, im located on Israel for now
If there is no hardware different is it possible to flash a firmware from Google edition HTC to another versions?
So I dont have to wait too long for updates
Thanks again

The main difference in GSM version is the frequency/band it uses for 3G/LTE.
Everything about the GSM version is the same except for each have different frequencies enabled.
So find out in Israel what cellular company you will be using and what frequencies their 3G and what LTE band if any. Then you'll be able to pick which m8 is right for you.

Gunmetal finish is available for a great many versions/regions, so telling us that alone doesn't say much.
But GPE full conversion is possible with unlocked bootloader and I think S-off also.

asop custom roms? and custom roms on verizon?

I understand the device works on Verizon but am curious if all custom roms will support the bands verizon requires? I am guessing that the modem is complete (works through and through) for all bands but not sure so am wondering if separate roms will need to be created for the network (really theirs only one, verizon) that uses different bands. I would love this device running Liquid Smooth or similar on verizon!

This shouldn't end up being the case as custom ROM's will use the Nexus binaries provided by Google available to developers which will support all of Verizon's band so no need for a Verizon specific RIL implementation for example. As a result you will be fine to run AOSP based ROM's such as Liquid Smooth. The thing for ROM's will be more about whether you have the American model of the device or the International model. Let me me know if you still have questions!

If your going to use it on Verizon, I would recommend going with the North American model which is model number LG-H790 for US carriers. Both models will have a great selection of custom ROM's and goodies, and with only minor differences between the two models the hard working developers won't need to do to much extra to support both.
