I am sure we all know about the lack of support for CDMA on the OnePlus X. I was wondering if it is possible to create a sort of relay that uses a CDMA sim and broadcasts to a GSM phone and vice versa. I don't know if this is an existing thing, or possible, but I thought it would be an interesting idea to research. Does anyone know anything about this? Is it possible?
Thanks,
Lev
Also, sorry about my ignorance on this topic- I only received my OnePlus X today, and it is my first phone.
In fact you want to operate a GSM BTS (for your OPX), that will communicate with another BTS using CDMA frequencies.
So like 2 BTS, a laptop, and batteries in a backpack, just for using your OPX in CDMA regions.
Why not, you could do it with Osmocom I guess.
But, being more serious, OPX supports some WCDMA bands. If not sufficent, just buy another phone. Nobody will ever bother to work on that.
I was reading that two of the missing bands were software locked. Is this the case?
I just decided to attempt this as a school project, I was just wondering if anyone had any knowledge or advice they could impart. Other than the common, "You can't do it" advice.

I can't seem to find an up-to-date tutorial on performing this process. I found some from mid-2009, but people are commenting that *228 doesn't work, this thing doesn't work anymore, that thing doesn't work anymore. Has anyone done this process recently?
I am trying to get this phone onto Verizon without a data plan since I will just be using wifi.
As far as I know, Sprint phones are GSM, VrzWls are CDMA. Totaly different frequencies. It is impossable (without an enginering degree and a lot of solder) to make one work on the others towers.
Sprint phones are not GSM they are CDMA

There are a lot of people on these forums that have done it - I just can't find concise up-to-date directions.
have you tried loading a verizon prl on the phone? i have my sprint tp on pageplus, which is a verizon mvno, and it wouldn't program ota until i loaded the prl.
I have not tried loading anything yet. I am still looking for directions that are not from 2008. Also, I have no interest in custom roms at this point. I simply want the Sprint phone to work on the Verizon with the least amount of work.

Step 1. Grab your phone and take it to a Verizon store to have it activated on their network...
End of subject
There are other things that you can do manually, but since the only thing you are interested in is to have the phone working for a different carrier, then that is all you need to do.

The only true part about Thelgord's statement is that Verizon is a CDMA network. Please don't pay attention at anything else in that statement.

What? I thought Verizon wouldn't do that. Plus, don't I need to convert radios and such from Sprint to Verizon?
Has anybody tried to flash radio from Desire to Thunderbolt in order to get that ***** running on wcdma/gsm in London for example??? I'm new to IT with mechanical background so asking what makes sense to me... Also would ROM from Desire work on TB or am i talking about "jet engine on a bike"????
Please help i really need to have TB running in UK
If you want to carry around a large 4.3" paperweight, then feel free.
Not much help it was ha ha
How high the risk of bricking, is it 100%???
Doubt a rom will boot, but won't brick it. You'll just end up having to reflash a compatible rom. Radio on the other hand... I wouldn't attempt.

I think you're forgetting those are 3g phones. If you flash a 3g only radio on the thunderbolt, it's not going to work out. Maybe the rezound would work because it has the same LTE chipset, but I'm skeptical and it's not something I'd really want to try.

I honestly don't think its been officially tried. No kind of previous docs stating "oh noooo, bricked my phone" or "wont boot" nothing. Just angry mods saying "if that worked, they would've let you know by now"
Posted from my 1.34ghz, Infected, Themed Out, Lightningbolt.
Yeah took us a few attempt's to go in to space, another few to land on moon....
if i'll go ahead and try it out would you guys suggest a phone that is related to thunder bolt the most(hardware/sofware wise)??? Is it Resound or is it DesireHD???
i hate it that only a few ppl have the thunderbolt outside of the us or a zone without a CDMA company im from Romania and i did unlock the phone using the XTC - Clip but the radio...its messy i tried to change it to gsm and it just returns to the previous selected thing...i tried shutting down radio then selecting GSM and then turning it on ...it stayed GSM but no signal
Any of the GSM abilities outside of LTE in the chipset for the device would be locked by the radio firmware. Firmware is of course proprietary to Verizon and modding it is technically illegal I believe. That doesn't mean you can't go and try to flash something from another device, but I'm not going to be the one to try it. Only one worth trying is the rezound though. I'm not an expert on radios in embedded devices, but if the radio is isolated totally from the system, then I don't see why it would not work as the higher level RIL libraries on the Rezound are the same.
However, don't take my word for it and run and flash and blame me if it bricks of course
Hey guys, I'm a noob, please don't hurt me
I'm an American living in Japan and I just bought my first smart phone...the EVO 3D (3G) for AU by KDDI...I'd post a link, but I'm not yet allowed.
Their non-3G network was CDMA...so I assume that their 3G is also CDMA....can anyone confirm that?
Under that assumption (CDMA), we're still waiting for ICS, so I'm wondering what you'd all recommend I upgrade my phone to while I wait. I'm not a fan of the stock Android 2.3 that came on the phone, and I'd really like ICS....but if there is something I could use now, that might be fine with me.
Also, what are the basic steps I need to follow, I found the sticky thread in the dev forum, but I'm not sure what stickies would apply to my situation. I'm guessing I'd have to start with a root kit, and go from there....but please fill in the gaps, thanks

Lol I see.
Chances are that you will not be able to activate any CMDA phone from overseas on a network here in the USA. The big networks like verizon and sprint will not allow foreign IMEI numbers to be submitted to their system for activation.
Do you happen to know what frequency the cdma network you came from runs on? Look behind the battery

When I had AU by KDDI when I was living in Japan is was CDMA. As far as I am aware the Japanese version wasn't able to be rooted using the CDMA methods here in the development forum. Also the ROMs here would not work on your device and would actually need to be slightly modified to include files from your device to work, but you don't have an ICS ROM to use for replacing files.

That's kind of the conclusion I came to, after running through all the different root/unlock methods, I came across issues in every single one, and my skill / confidence isn't high enough to really make a go at figuring it out.
Only thing I haven't really attempted is downgrading from hboot 1.5 to 1.4, partially because my software version is different from the instructions, and soft bricking the phone makes me nervous considering the potential incompatibilities.
I think our phone is more or less the same as the sprint phone, just on the Japanese frequency. I'm hoping that the sprint announcement means we will also be getting ICS soon... but who knows
I know, I know... WHY SPRINT???
I'm locked into a contract.
Not very glamorous, right?
Anyhow, I acquired a Verizon Droid Razr Maxx and want to use it on Sprint. How can I do this?
I know the MDRM is dual band and has a radio with CDMA 1900 (which is what Sprint runs on) so it should be doable, right?
I really don't feel like forking over the phone and cash to Shady-Person-on-Craigslist or Shifty-Eyes-Guy-Behind-the-Bullet-Proof-Gas-Station-Window.
I'm curious about this myself. I have been looking around with some mixed info on the subject. Some people say yes some no. But noone says how or why. Any one with a definitive answer and a technical why not? It seems clear the phone supports it from a hardware perspective. What would be the limitation besides the obvious software/firmware imposed reason?
I've never flashed a phone to a different CDMA provider so I thought I'd ask here first and see if anyone had knowledge of how to do this? Or point me in the right direction to somewhere to learn how to? I've unlocked the GSM radio for use on att already and I'm sure it's a similar procedure, but I followed a guide to do this and have little experience with it. Thanks in advance to anyone that has information on this.

The CDMA providers blacklist phones from being used on other CDMA providers networks. "Flashing" in this sense is stealing and ESN/IMEI from an existing phone and cloning it to your phone. Not only is it extremely risky for your hardware, it is extremely against the law and cannot be discussed on these forums.
Certain phones like the Rezound and the Dinc4G have additional feature of GSM radios added for compatibility with oversea networks, you aren't really flashing anything so much as the phone reconfigures itself for GSM or CDMA depending on what kind of SIM card it finds.

Umm. Not true at all actually. I had a P+ dealer switch over my phone with a bad esn (mother in law didnt pah her bill) and they didn't use a "friend" phone. It doesn't require stealing a phones imei or anything it requires a lot of work to port it to a different carrier, but doesn't require anything illegal. Not to mention what you're talking about is also based on the staye you are in. In the states it js legal as long as you aren't copying two have two phones on one service and is completely legal ( state dependant) if you own both phones. Check your facts.

as far as using it on gsm networks, yeah its possible you just need to either do some things (I could dig up a link if you want) on stock and have it kinda work, or find a rom that supports it and flash that (recommended, what i'm gonna be doing). and flashing phones to other networks i am pretty sure is illegal, i know from experience, i tried to work that out on xda and they sent me away saying this isnt a topic allowed of these forums, so if you still want to know about carrier flashing i suggest another forum
but anyways just making sure i am following you right, you want to gsm unlock but want to use it on virgin mobile (a CDMA network?)

It should be possible, I've gotten as far as getting the NV values on both radios, but it seems as the 9k wants to search for signal on 800mhz only, at least according to DFS.
The Thunderbolt is able to get 3g working on Boost/VM/etc. at least from what I've seen. Considering the similarity between it and the Rezound I was hoping it would be easier...

Flashing phones to different networks aren't illegal. It is a state dependant thing. I went and had my note 2 flashed over at a business in the middle of a bestbuy, guitar center, more big businesses. (Aka, big businesses near ~ not a shady place)
Yes, I know that Virgin Mobile is CDMA. I wanted to know how to unlock the GSM antenna purely for education purposes.

It is easy, but only to people that already know how to do it. The process is similar for most phones and doesn't require a lot, but most that try to do it dont know what they're doing and it takes them forever. What we need is a good electrical engineer.

Quick update:
The Rezound can work on Sprint-based towers, at least with leaked global (4.03) and stock global (4.05) radios. It took me couple of days of fidding via DFS, but right now I do have 3G working, albeit with the stock ROM complaining that mobile data isn't working. Trying out couple of ROMs to see which ones is usable.
Most important thing is that the 8K radio needs to be set to NV_ONLY but that 9K can be set to RUIM preferred. Also, flashing the firmware (from the recent 4.05 global update) will reset the 8K radio to RUIM, which is a good thing/bad thing. Good thing is that if you ever want to NV reset (since hard resets do not seem to wipe NV), flashing the latest firmware/radio should get you back to RUIM/stock PRL/blanked #. Bad thing is you need to fiddle with some of the settings in DFS again, but at least it's only for the 8K radio so far.
Another thing that probably made it work was to use the same PRL from the phone Sprint thinks you are using. For me this was the 61009 PRL. Profile info only needs to get stuck into the 9K radio and I don't think you really need to bother with the NAM2 stuff. But again, I've done too many fiddling to be able to say for certain.
