As of a few days ago the Dev, xDarmario (http://forum.xda-developers.com/showthread.php?t=1961403) has release a patch that allows any R800x user to flash a GSM ROM, then flash his patch and you can use that ROM, minus any phone functions.
My question is, is anyone interested in having a go at making a CDMA patch? IF its possible to make a generalized CDMA patch that would mean, if it works, that any R800x user can take advantage of any GSM ROM. I am aware that there is alreadya the FT5 CDMA Patch and the AOKP CDMA Patch but neither of those worked for me.
Thoughts anyone?........
I guess no one with the R800x would be interested in working together to see if a CDMA patch can be made........... now that there is the xdarkmario patch to allow install of all GSM Roms without missing homescreens

I wondering why flashing a GSM ROM would brick a CDMA Desire? Flashing just a ROM shouldn't affect the radio so what is the primary issue. From there, I guess my next question would be what is need to port a GSM to CDMA?

its because they have diffrent cpu's, the radio band a device can use is hard coded into the cpu ......

Sorry - but you are essentially wrong here.
The Snapdragon SoCs that power both devices essentially have two cores on them - one which handles the OS, and one which handles the radio. For the most part, the OS "core" (which is the ARMv7 part) is going to be identical on both the GSM and CDMA Desires, and the difference lies in the radio core.
However, that is not to say that flashing a GSM ROM (without radio of course) on a CDMA Desire will brick it, but I'd say it was fairly unlikely since recovery should be unaffected.
When I had my Hero, the first leak of an Eclair ROM came from the Sprint Hero (a CDMA device) and it was relatively easily ported to the GSM Desire.

Interesting. So the fundamental difference is probably in the kernel and roms would have to be built from there on up?
could u basically flash a gsm kernel to a cdma phone then? since it wont change the radio. (noob question i guess)
or if u cant, what is the difference between gsm and cdma kernels?

why do you want to take the risk? I don't really understand kernal that well other than its like the super basic coding of the operating system or something like that, but you might be hard pressed to find such a kernal anyways and I really don't think that's enough to make it work in the first place. All the software/firmware/radio versions/etc... have to match up or "sychronize" so to speak is my understanding. And yes Radios do come with stock ROM's, but they sometimes don't always come with Custom or cooked ROM's. Sometimes I flash a stock ROM just to get the stock radio then I reflash a custom ROM back to it for example so I have the stock radio with a custom ROM like mighty ROM

Did you mean to quote me? Are you replying to me? Most CDMA only phones don't use sim cards and have no slot for them. Additionally the only countries that use CDMA is USA, Japan, South Korea, and India, all the phones in the rest of the world use GSM/SIM technology. Theres only a few exceptions to the CDMA only rule such as the touch pro 2 which is designed/capable to work both on CDMA and GSM networks

Flashed many times GSM ROM to my CDMA Desire, just to check if it works... Didn't bricked my phone totally - recovery was working fine. I use it as a pad, no cellular connection, so I figured out if OS part will work than I don't mind. But it didn't, 95% of a time. I think Ethereal2_R3_Final was the only one that worked, but not sure if it is GSM now. Go and play around - it's reasonably safe. Running Oxygen CDMA now.
what would you recommend to get your device up and running again if your back up recovery fails?

Says who ? My ZTE Blade N880 CDMA have simcard slot.
So, my question is, is it hard to porting from custom rom for zte blade gsm into zte blade cdma? Thx.
Hello, I saw and tried the cdma version of Keiran's Darkforest ROM, while I like how smooth and the Sony Ericsson launcher is but I missed t-mobile's theme chooser from team freexperia's cm7 rom. I was hoping some devs would tell/write what some of the key differences are between gsm and cdma are. I've read somewhere that one core is for radio and another is for everything else and the radio core is the reason why're so different. Idk how true that last sentence is though.
why not download the cdma version of cm7?
Because I want to try and convert other gsm roms to cdma.
You'd be the first to convert a PLAY GSM rom to CDMA if you do, so good luck
Seeing as all roms are different what one in specific do you want to convert?
What about KeiranFTW's Darkforest rom? I thought that was a conversion?
And I have a couple I'd want to do imo the first one I'd try to do is ICS MIUI from pricey2009's thread. I've seen a number of posts/threads saying its possible so this thread is to ask for devs and ppl to post what they know and try to make it work.
start by replacing the following libs with the cdma variants
libcm.so
libgsdi_exp.so
libgstk_exp.so
libmmgsdilib.so
libnv.so
liboncrpc.so
libpbmlib.so
libril.so
libril-qc-1.so
libuim.so
libwms.so
Alright, I'll try with doom's kernel and see how it goes.
although I think the kernel might need some work or it could be the miui rom. because just replacing those ^ files my phone wont go past the booting DooMkernel screen. Wiped data, cache from stock rom before I ran the miui updater script.
Any news or updates on your attempts at converting a GSM rom to CDMA?
Not anything new unfortunately. : (
I don't think converting the aokp from was new either as its cm9 based so I did the same thing as pax did for cm9. Except super venom did the real work compiling it with Xperia vendor/ parts whatever.

The most we can do is in ICS.
AOKP/CM9 are fully compatible from a GSM variant.
Sony Beta is a different story.
I have an R800x which, when stock from Verizon, has FW version 3.0.1.E.0.88. If I flash a stock UK ROM, it shows as 3.0.1.A.0.145. Both allow CDMA to work as well as calls.
The Sony Beta site states you must be running at least FW version 4.0.2.A.0.42, which would seem to mean the R800x cannot run ICS. However, there are modified versions of CM9 that work including data and calls. There are also new patches already to allow the new Sony ICS Beta, which flashes just fine, to have CDMA data, wifi and soon calls.
How is that possible? And does this mean that it would also be possible to use similar patches for ROMs like JokaWild or DiXperia Monster to work?
I'm trying to figure it out but right now, I am

The .145 was the last UK firmware that was able to work on both CDMA and GSM. That's why you'll get that one to work as well as the .88 version.
As for making the newer roms work with the CDMA, I believe that chevyowner and others are porting specific lib files over from stock CDMA, but I'm not completely sure.
Seeing as how CDMA users are on the short end of the leash for ROM selections, I have given it some thought and though I do not know much in the way of porting and or programing for that matter I would like to attempt to port a GSM ROM to the R800x. Can anyone give me some advice and or tips on how to go about that? Thank you in advance.
Or, is it possible to simply make a CDMA Patch that you flash separately to make a GSM ROM work with the CDMA R800x?

There is a patch in the cm9 nightly build thread that kerian made that I guess works on most aosp builds..I've ported the gsm version of cm7 to cdma changing some libs, a few build prop tweaks,and changing the updater script. You should pm pax(Peter) he may know more about it then I since I'm so use to gsm models

I was thinking of trying to port some of the awesome ROMs here, like true ancestor, jokawild, etc. Obviously I would ask for each Devs permission. I want to retain the Xperia PLAY framework as I game a lot on my phone.
On a side note I do have the CDMA Patch but its for CM7 and or CM9....... is it possible to use this for the Xperia GSM ROMs?
I did PM Pax as you recommended,
I was also looking in on how to do this. I've actually been trying to make jokawild work on cdma

Well I have tried multiple times and spend hours on this. Had to ftf a few times as my fastboot almost stopped working. It would flash green a couple times then go dark. Battery pulled a few times and was able to ftf back. Now back to my nandroid. Not sure where to proceed. I even tried the CM9 cdma patch as a base, not the files from it just poked around to get an idea. I do say that trueancestor does give full rom but no cdma or 3g data. But you can ply with the full rom on cdma.

I found this Rom that I really likehttp://forum.xda-developers.com/showthread.php?t=2108386. I was wondering how to convert it to a CDMA rom. I know there are patches that can do it like the AtariiKieranFTW9 patch, but all of the threads I can see say you can't ever port a GSM Rom to a CDMA phone. Can anybody tell me why some roms are patchable and some roms aren't?
You can use use custom jb and ics on your R800x. But you cant you use custom gb on your r800x. The "x" is there for a reason no support from developers and because they dont have the "x" themselves. So what they are doing now is guess work. Like I said before you can install jb and ics on your R800x. You will have voice but no data or internet access from your provider.

I know that if you install a GSM rom on a CDMA phone that you can't get Data or internet, but I also know there are some roms like AOKPlay and CM9 that were written for GSM where you can use the AtariiKieran patch and use the full features on a CDMA phone. What I'm trying to understand is why that patch works for those ROMs..
