13NOV: CDMA Rhodium Q&A: GSM, 3G Bands, SIM UNLOCK, ESN, IMEI, HARDSPL, ROMS, FM, GPS
I've seen a million (not a million literally, but close enough) of these threads in all shapes and sizes around the forum, yet there still doesn't seem to be a definitive answer to everyone's questions.
Telephony Network & 3G band compatibilty
SIM Unlocks
HARD-SPL & ROM compatibility queries
Domestic (US) and International Usage
Usability of Both CDMA and GSM radios
GPS
FM Radio
As someone that shares most of the comunities queries about the Rhodium CDMA's compatibility, I am listing all the questions that I have encountered around the forum and a format in which the answers must be provided in order to eliminate any unwanted chatter in order to be able to get to the "bottom of this" ASAP.
ANSWERING FORMAT
1. Please indicate the Q number to which you will be providing your answer
2. If you are going to describe compatibilty with any service provider, please indicate the following before you start answering or asking any questions.
Name of the Serive Provider: Verizon / AT&T etc.
Country of the Serive provider:
Network Type: CDMA / GSM
3G Bands supported by the service provider:
QUESTIONS
Q1. Are the Verizon, Sprint and Telus versions of the TP2 identical as far as the hardware is concerned? The only difference I can find between the 3 of them as compared on PDADB is that the Verizon and Telus versions support only UMTS2100 instead of both UMTS 900 / 2100 like the Spint version. We need this sorted out. Is the info at PDADB not accurate?

Q2. As far as I know, ESN is used for CDMA phones and IMEI is used for GSM phones. Can anyone check to see if the CDMA Rhodiums come with 2 identifications numbers, one for each radio?
A2. Seems like it does come with both, although the ESN in this case is referred to as as an MEID
Read This
Q3. Again, as far as I know most CDMA service providers around the world offer phones without a SIM card (or even a SIM Card holder). They program the "SIM Card equivalent identification number" (maybe the ESN itself is used as identification) into the phone and that is how it identifies itself on the network. More recently, I have started to notice that CDMA phones are coming out with SIM card slots and even CDMA service providers (like Verizon) are offering CDMA SIM cards. Now multiple questions arise from this.
a. Does the Rhodium allow your Verizon / Sprint / Telus telephone number to be programed into it or do you receive a SIM card for your telephone number?
A. All CDMA Rhodium's that come from the carrier are programmed with the telephone number on them (Well it's not exactly that, but for the noobs that just means that you don't need a SIM Card.) Some users (Verizon and Sprint) receive a GSM SIM card along with the phone. That is just for roaming purposes. If you are ever in a country where Sprint / Verizon don't have a roaming agreement with a CDMA provider, then it will seek out a GSM carrier that they do have a roaming agreement via the GSM radio and SIM card. That's the only reason it's there. It (the SIM Card) serves no purpose while you're in the US.
b. Does the SIM card slot accept SIMs for both GSM and CDMA networks?
A. Ok First things first...
I'd like to correct something here regarding the "SIM" for CDMA. It's called an "UIM" or "RIM" for CDMA networks. It looks identical to a GSM SIM card but believe it or not, United States, or in North America, the UIM/RIM is integrated into the phone, where the rest of the world such as China, the users can remove the UIM/RIM just like GSM-counter parts.
We still don't have a concrete answer if the SIM slot will accept UIM/RIM cards although chances are very slim that it can.
c. If the Rhodium supports having the telephone number programed into it, does that mean that I can have another CDMA service provider (in a different country of course) delete the existing number and program in a new telephone number?
A. Of course you can. It just depends on the service provider although not all of them might co-operate and would be willing to do this. Why? Simply beacuse it might affect their phone sales.
If you are willing to do most of the work yourself, check out this thread at PPCgeeks.
Further Reading
d. Essentially, the question I want answered here is, can I use 2 telephone numbers (one CDMA number programmed into the phone and another GSM / CDMA number via use of a SIM card). I understand you cannot have both radios active at the same time and that's not what I am asking.
A. Yes, you most certainly can although I doubt youll be able to stick a CDMA UIM/RIM into the SIM Card slot and gain access to a second CDMA carrier.
Q4. This might sound like a silly question, but a lot of people including myself aren't a 100% sure about it. Once HARD-SPL is introduced for the CDMA Rhodium, can we use all the ROMs cooked here at XDA, or do we have to use ROMs that are specific to these CDMA models?
A. NO, ABSOLUTELY NOT! You cannot use a GSM ROM for a CDMA device. You might brick it! Of course if you do something silly like that, you might be able to recover it, but why do it in the first place?
Q5. Leaving T-Mobile and AT&T aside, most GSM 3G networks around the world use 900 / 2100 bands. The CDMA Rhodium (atleast the Sprint version) supports both. Does this automatically mean that 3G would work on this where ever 900 / 2100 is available? or is there more voodoo magic to this? If I understand it correctly, then this phone is exactly the same as the HTC European version (except the Front CAM) + the fact that it has a CDMA radio as well?
A. Yes, it should work!
Misc Questions
Q6. Is there a SIM Unlock tool (or any other kind of paid service / hack) available to make this phone compatible with the US GSM service providers?
A. YES YES YES! Olipro and Cmonex have made this happen for real. Works with all CDMA Rhodiums.
General SIM Unlock (for worldwide use): Read This
Sim Unlock for Domestic US carriers: Read This
Alternatively you can do the following (There's no point really with the unlocker now available)
Verizon: Call Global Services Customer Care (1. Customer in good standing can get it done immediately after purchase. 2. New customers or defaulters need to wait for 60 days) After it is unlocked, you'll have no problems making it work with any US GSM carrier.
Sprint: It's already unlocked, but won't work with US GSM carriers.
Telus: I'm not sure if Telus does that for you but thankfully enough there are a lot of paid unlocking services available starting from as low as $13.00.
Option #1: eBay
Option #2: Others
Q7. This phone seems far more superior to the International version simply because it supports CDMA and has everything else that the International version has (except the Front CAM). Is there any reason why this is not the preffered phone for ALL?
A. It's just a matter of taste and also some people really want that Front CAM from the HTC Branded Rhodium.
Q8. What is the deal with the FM Radio?
a. Is the hardware built-in for it or not?
A. Nobody is entirely sure about it yet, although based on some of the digging around that the folks over at PPC Geeks have done, it seems the hardware might be present. You can follow the development for that here. Get's interesting around Page 5.
b. If the hardware is present, then which port needs to be used as the antenna? Ext USB or the 3.5mm jack?
A. We'll find out when someone figures out how to make it work.
c. A lot of people report that it's locked or doesn't work. Any sign of a hack for it yet?
A. Not yet. There is one available for the GSM versions but that doesn't work for the CDMA Rhodiums.
Q9. GPS...
a. Is it locked to only Sprint's or Verizon's navigators or can Google maps or any other third party navigation / map software be used?
A. It's NOT locked. 2 Confirmed reports state that both Verizon and Sprint TP2s work with every navigation and map software under the sun with pretty accurate locks.
b. If it is locked, where is the hack for it?
A. Not required. It's NOT Locked
c. I'm having issues with getting accurate locks.
A. Follow the links to these discussions.

Q10. Front Camera. There isn't one, is there?
A10. Nope. No Front Camera for CDMA Rhodiums.
Q11. Headset
a. Do you get audio (stereo output) from the Ext-USB port like with the GSM versions?
b. Can an old headset with the Ext-USB connector work as a handsfree?
c. Telus comes with a 3.5mm based handsfree. What are Verizon and Sprint customers (who don't get one) doing about it?
A. Click HERE
Answer to Q9 in regards to the VERIZON version - no, it is not locked to the VZ programs. I've successfully used the GPS (with nearly instant locks) on both Google Maps and Garmin MobileXT.
Q9 GPS is unlocked on sprint TP2... All gps applications work accuratly
I want to know the answer to whether the UMTS900 in the Verizon phone simply isn't installed or if it was just an omission at PDADB.
Q4: You need to flash CDMA phones with CDMA roms. Flashing with a GSM rom will probably brick it.

Although I'd imagine that most ROM cookers will release both versions of their major releases. At least, I'd hope so.
I get conflicting reports about that.
I've read in some places that as long as you don't cross flash the Radio ROMs (GSM for CDMA), then it's ok to use the generic ROMs available for GSM phones.
Also, can anyone check on the box of your CDMA Rhodiums to see if you ahve both an ESN and an IMEI number?
What are you guys doing about the handsfree? From all the unboxing videos I have seen for Verizon and Sprint TP2s, they don't provide you with it although the Telus version comes with a 3.5mm based headset. (Not the Ext-USB one)
My answer comes from my reading when I had the VZW TP - the CDMA threads were very specific about being CDMA only (and warned of bricking if you cross flashed). The radios will be different in them - so I am imagining it will be separate still. I don't cook - so maybe one of the more experienced can weigh in.

I can confirm that too, only tried it with Google Maps though. To anyone having issue with the GPS make sure you run the QuickGPS program that comes installed while you have an active data connection. It downloads data on GPS satellites or something that makes the locks much faster than without this data.
Q8: Works. Had to install it twice (First time it said not supported) but it works.

My take on it is that, currently, we can't flash custom ROMs onto it. That's a huge part of the community here, and really, very often custom ROMs are superior in every way. Plus, you get a "new phone" feel every flash.
Once HardSPL/whatever comes out, perhaps everyone'll love the CDMA/GSM version. Who knows. In any case, Verizon's already sold out and most everyone on VZW who has one loves it, so perhaps just wait for time to tell.
Another question.
Have they in any way crippled the Video Out feature on the CDMA's?

I can confirm that the Ext-USB stereo headset that came with my Sprint Mogul works just fine.
I just bought a brand new sprint touch pro 2 but I'm looking to use it on GSM US network. I do know that it's sim unlocked and it can be used with any GSM carrier except for US carriers. I know there's currently no unlock code or app for CDMA tp2. I want to know if the phone is missing the hardware to use with GSM US carriers or is it just locked with software and if it's possible to sim unlock it in the future.
It probably just is software. The verizon model works with US carriers after you receive the unlock code.
Just a matter of time before someone here figures it out.
Also regarding the Radio. This is the PM I received from LifeStealer
LifeStealer said:
So... its installed and picking up stations I know to be be real (Via my stereo). But no sound. So it picks up but doesn't play? I dunno I didn't have a headset when I first tried it and now that I have one plugged in maybe it needs the default HTC headset?

I can confirm that you can INSTALL the program and START the program, but it doesn't actually pick up any stations. The interface allows you to dial in any frequency but doesn't actually pick up any signal despite the fact that it says "Now Playing".

Did you have the headphones plugged in? I read somewhere the headphones have to be plugged in to pickup radio stations.

I have just upgraded my O2 XDA Mini S to an O2 XDA Orbit. I'm trying to pass the wizard on to my son who currently is in a monthly contract with the UK 3 network. Both the Wizard and Orbit will not recognise the 3 sim. I've searched widely and find a lot of conflicting opinion but some say that the 3g card will work on a 2g phone (albeit talk and text only without the 3g frills). Does anyone have any advice. The wizard is unlocked and accepts O2 and Voda cards. Is it the O2 software that needs replacing or is it that the card will never work on this particular unit.
Thanks
Three Network now has both GSM and 3G coverage for a full UK coverage. As such, it *sometimes* works on non-3G phone. Depending on your area, I think. But, in general non3G phone (i.e. the Wizard) doesnt work well with Three

Thanks for the rapid reply. Yes, the fact that 3 backs up on to Orange to give full coverage set me wondering. The phone will not even accept the sim - saying no sim or invalid sim. Is there some kind of barring actually operating on the sim to prevent it's recognition by any phone other than a 3 supplied unit? Odd one this.
Well, the common one is SIM-LOCK phone, that the case where the phone is locked to a specific SIM only. i.e. A-SIM in A-Phone, B-SIM doens't work in A-Phone.
However, it is unlikely that you have a Phone-lock SIM, or rather, barred IMEI. That is, the network only works on phone (i.e. with the IMEI) that is registered with the network. Hence, A-SIM will not work on B-Phone because B-Phone's IMEI is not registered with A-Network. Technically, you can do that, but I can't seems to see what's the business benifit of it. Further, you may check this buy going to their website and see if they are selling SIM only package. If so, they are unlikely to be blocking unregistered IMEI, more likely they (the phones) are not compatible with three network.
If you were to go to the Universal forum, there are people using Universal (a 3G phone) with Three Network. I'm not sure if these phones are from them, but my hunch is they are not.
Thanks for the info
Regards
I have this problem on mine too i wan to use a 3 sim in mine, mine is unlocked to all networks but three sims dont work, believe three sims are a different type of sim and thus dont work in phones not designed to take that type of sim, as my bro has a newer pocket pc phone and m sim works ok in that, think iv read somewhere they use different voltages or frequecy or something?!?
not sure about sprint, but Verizon when I use to hack motorlas, had the hardest registery to hack, and graphical interface witout flashing a complete new Rom, and I couldn't stand not beinging able to swap out phones with just a SIM card change, Verizon and Sprint, are tooo controlling, and I would avoid them, sure clarity and service are good on the CDMA network, but, I can't stand feeling like I'm being controlled, and the slight degrade in service doesn't offest the negatives

Couple things
1 - CDMA Touch Pro 2 also has SIM slot and should work on GSM networks (I haven't seen it myself so 'should' but the SIM slot is there in the spec) - You can swap whatever SIM car you want in the CDMA TP2.
2 - T-Mob reception at my house sucks
3 - I got 28% monthly service discount for Sprint vs 15% for T-Mob from my employee
Conclusion: What is bad for you isn't bad for everyone...
Actually, the GSM is locked so it only works outside the US. (I think it is hardware locked too so it would be very hard to crack.)

I don't like feeling controlled either, but I like staring at a $500 phone with 0 signal bars even less.
Where I live and drive, any phone running on anything else besides Verizon is as good as a brick.
Sorry man, The Network > All
And honestly, I don't see changing phones as an issue at all. With Verizon you can swap out phones in 10 seconds online via ESN swap. And as for selection, aside from a very few devices like the iPhone or Hero, there are CDMA version of most major US based GSM phones. The only area that CDMA really lacks is that you can't activate overseas phones like some of the rarer Nokia's, but those phones usually don't have US 3G anyway so wtf is the point?

Actually, Sprint is coming out with their version of the Hero.
@labsONE
They do have GSM capabilities. The GSM only works oustside the US though. Read the FCC filings. They said they locked the GSM through hardware and firmware so it only works outside US. Inside US, you have CDMA.

Um...that would be outside the US. Sorry, felt like being a ****.
I personally like the phone and all of it could be capibilities...
There's a SIM slot and I have a AT&T PAYG card sitting in it - it works fine (this is a Canadian Telus TP2.) Unfortunately I can't get the 3G working yet but I am sure HSPA will be able to be leveraged sooner or later with some tweaks.
CDMA reception is very good and data speeds on EVDO are fast.
Actually both Sprint & Verizon allow you to swap between the phones you are using online.
Verizon allows you to switch even easier, by just grabbing the phone(Verizon) you want to use, and dialing *228, you can activate it via an automated system.

MightyROM
I have the CDMA U.S. Cellular Version.
I used MightyROM.
It apparently first used a CID Unlock to be able to install itself.
MightyROM is completely Windows from the Ground up as is advertised (freeware) and acts more like an upgrade to windows mobile 6.5 so gives a definite windows feel to it with extended capabilities over the original WM6.5. It allows for Provisioning/Preparing of Data Services to any of the other CDMA carriers but it wouldn't register on Boost Mobile's site after provisioning to Sprint (Sprint owns Boost Mobile) when I tried to activate online and said it was invalid MEID so I'm guessing you have to spoof the MEID # to be able to get it to work on that carrier because it should have worked if it was truly CDMA unlocked and Provisioned to Sprint (I have activated Sprint Phones on Boost Mobile in the Past without much trouble) but I don't know of any way to do that(?) but the CID unlock is essentially a spoof also right so should be able to somehow right? I havn't had a chance to check and see if any of the other carriers would accept the current MEID but I did try a bluetooth PAN connection to a blackberry running on boost (that is actually also a Sprint branded phone lol) but was unsuccessful although it looked like it was about to work for a moment, might need some minor tweaking?
I also popped a couple SIM cards in. The phone seemed to at least partially acknowledge them but the program seemed to be acting buggy so I'm guessing that has to do with another security mechanism blocking it in the extended Flash ROM.
I'm guessing it goes in levels and the next security mechanism is what Olipro call's the security unlock. Still haven't figured out or found any information on what this is or does but apparently it's part of the extended ROM. The might ROM seems to unlock the CDMA and allows to change to Global and GSM modes after install (Before I couldn't change it, it was locked into CDMA only) so I am extremely curious about the extended ROM and what it's programmed to be doing as far as closing/preventing available connections that should be there but aren't. The hardware is definitely there, it's just not being used because it's blocked by the programming. Seem's like it's in the HKEY_LOCAL_MACHINE/System/StorageManager/AutoLoad/Ext_FlashDRV when you have ROOT Superuser access in a Regedit application (I'm using Rescoe Registry app) but I don't know what values to change or try and implement and I don't want to mess anything up so will have to keep searching unless someone knows something?
I've heard that one of the files in the extended *flash ROM is nearly essential to have a working touch screen so I don't want to try to delete it all at least for that reason. Although, If I could correctly identify and locate the essential files needed for the smooth operation like the touch driver then It seems like I could just move them into the main flash ROM and then delete the extended flash ROM Carrier Junk. That would certainly take care of a lot of issues it seems and free up the space/memory?
Anyone know where I can find the Key Values and their associated meanings for the registry?
I also tried flashing a Radio. Even though I am CID unlocked the flash failed so this definitely makes me think there is something to the security lock that Olipro talks about, but as I said, I can't find any info. on it. Help plz?

there is no extended rom partition anymore, that was a feature for older htc phones..
don't worry, you can't just delete the touch screen driver accidentally because it's in rom. you would only be able to remove it if cooking a rom
the US GSM networks are blocked in the radio firmware itself.
which radio did you try to flash? before flashing, be sure it's declared as compatible with your device model.
the security unlocker is here: http://forum.xda-developers.com/showthread.php?t=578642

I tried to flash the two sprint radios so far. First I tried the recommended one then I tried the other. I figured I should go with the sprint ones especially since my device is the US. cellular version and that is the RHodium400 or whatever its called that is pretty much identical to the sprint version, aside from some software, as I understand.
I am able to flash any ROM but the security/SIM unlocker is not working. I sent the ticket out just a little while ago. I got it yesterday but I thought since i was using windows 7 that i was going to have to install xp so I was working on getting a partition in my disk drive on computer and got side tracked (Never done before) into learning that but eventually it got so complex (mounted an iso and am supposed to install via grub menu in dos/linux) that I just gave up and figured I would just try and see if I could get installed on windows 7 first. I did, and it ran the first step fine, but won't do the sim unlock. Keeps saying device is in flight mode or IMEI is invalid. So sent the ticket and made another thread.
I was using MightyROM but I reverted back to the stock ROM and tried again. That didn't work.
Trying a few other things now. Gonna try and install Sprint ROM and see if that does anything. I'm guessing I need to change the radio/baseband but every thing I have tried to far fails. I figured the Security unlocker has to do with the radio but I havn't been able to find out a whole lot about it or what it does or what the encryption/restriction on the radio might even be for the U.S. Cell version.
Thanks so much for your reply. It is greatly appreciated
Discovered something interesting?
I just discovered something interesting. I installed the sprint stock ROM and it managed to change the radio/baseband version, but the network still defaults to U.S. Cellular. That is very strange. I would really really like to know what is the security mechanism that is making the phone do this
I'm guessing the radio/SIM is in fact unlocked like the phone says when I go into the SIM Manager thingy but somehow there is some programming from the U.S. Cellular carrier to always default to U.S. Cellular no matter what?!
Yes> This is very Strange. Not at all like an iphone :s
Here is what I have in device information on software:
Radio Version - 1.96.00 WF (Original -I believe- Sprint Stock Radio, Was 2.18.... Before I installed the Sprint Stock ROM/Radio Combo After HardSPL Unlocking -1.0 Olinex )
ROM - Mighty ROM
OS Version - 5.2.2....
Manilla Version 2.5.2012....
etc.... (Not that any of this -other than the radio and the fact that U.S. Cell Default - Seems to matter?)
I am super Confused!
Even mighty ROM Provision To sprint doesn't seem to completely Register. It will Provision and Provision all day long and install cab files all day long but always reverts back to U.S. Cell as the carrier and won't Detect any other networks in Comm. Manager/Phone Settings. I tried GSM and Global modes, and tried just about everything else from manually inputting the baseband frequencies and networks etc...
But like I said, there is an extended Flash Drv in the Registry Edit. You said it's not partitioned? I know flash drives are slightly different and that has something to do with the way it reads,stores, and writes information. But I don't know too much else. I think its supposed to have strong electromagnetic properties and is resistant to static electricity and drops or damage. I am wondering if partitioning a phone is also different from that of partitioning a computer?
Here are the few things I notice in the Registry that seem interesting to me/probable places for me to look:
H_Key Local Machine ... Security/PUshRouter/Security
Subkeys: (Default)
Provider10 - SecProviders.SyncMLSecProvider
Provider20- SecProviders.WAPXMLSecProvider
Provider90- SecProviders.UnauthSecProvider
HKEY_LOCAL_MACHINE/Drivers/BlockDevice/FlashDRV
There is also something Called BtC that is mentioned a lot. There are quite a few drivers and files associated with it.
And of Course : HKEY_LOCAL_MACHINE/Drivers/BuiltIn/Ext_FlashDRV is there. There is also FLASHDRV just below it along with numerous other files listed.
First Subkey of the extended FlashDRV is Defualt followed by:
Dll - OEM_FlashDRV.DLL (OEM is original Equipment Manufacturer? Maybe this is in reference to the carrier, U.S. Cellular?? or just HTC?) Lots of other keys besides that I have no way to identify what they mean.
I really am just trying to learn as I go along though. Don't have much other choice really want to use my phone how I want to use it not how some bs network wants me to use. I have hardware on this device that is completely inactive. I bought the whole phone I didn't buy part of it grrrrr this is like buying a car but not being able to use the back seat wtf lol
Hello All,
I hope someone can help me with this.
I have a TP2 (Sprint) and I need to use it for At&t.
The first thing I did was unlock the device using RhodiumWUnlocker from Olipro (and made my donation ).
I did all steps, and everything went fine. No problems. And it detected AT&T
Then I flashed the ROM with EnergyROM Leo Manila 2.5 WM6.5 v 16Feb2010, By NRGZ28. (File: Energy.RHOD500.23529.Leo_MaxManila.16.Feb.2010.rar) - Still all well, no problems.
Then it went back to stock and could not detect AT&T. So I flashed the Radio Version: 4.49.25.91 from this thread: forum.xda-developers.com/showthread.php?t=549939.
Now I cannot turn on my phone at all - No "touchpro2" screen, no bootloader, nothing at all. The phone doesn't react to any combinations of buttons to turn on or load up bootloader. When I connect the phone to the computer (Vista by the way) the charging orange light comes on for about 3 minutes then goes off. Then I press the power button and the light comes back on, but nothing else happens to the phone.
Please help!!! Let me know what's wrong and how I can fix it, please!!! I'll make another donation to fix it.
Thanks!
I'm no expert but it sounds like you may have flashed a CDMA Rhodium with GSM firmware. I had a quick look and it seems the Sprint Rhodium is CDMA, you should have a look at the CDMA Rhodium forum here:
http://forum.xda-developers.com/forumdisplay.php?f=517
I'm not totally sure of the GSM / CDMA thing because I'm not in the U.S. it's not something I need to worry about.
Good luck dude
Yeah the more I look at this, the more I am convinced this is what has happened.
You used CDMA HardSPL (RhodiumWUnlocker)
Then flashed a CDMA ROM (Energy.RHOD500 ...)
but your mistake was to flash a GSM Radio ROM (I followed the URL you gave and up popped the GSM Radio ROM thread)
I don't know if this is recoverable but searching the CDMA forum would be a good start. You can't be the first person this has happened to.
Thanks for the response, but I am certain I flashed the correct ROM.
*I went to the wingster website
*I selected CDMA ROM's
*Clicked on EnergyROM Leo
*Clicked on Download - Hotfile.com
*Selected this ROM: Energy.RHOD500.23529.Leo_MaxManila.16.Feb.2010.rar
When I flashed this ROM, the phone loaded up without any issues. The only problem was that I could not make calls because it could not detect the AT&T SIM card. So I flashed the radio shown on the post from xda, and the PC said congratulations, everything is complete and good. At this time, the cell phone rebooted and it just never came back on.
Thanks for the help!!
Thanks MadBeef, I will research the CDMA forum.
The Main ROM you flashed was fine. It's the Radio ROM you flashed that killed it, because your phone is CDMA hardware but now it has GSM Radio ROM on it. That's my theory anyway, I'm hoping someone a bit more experienced with CDMA will be able to chime in.
If you can get back into the bootloader somehow, you should be able to flash a CDMA Radio ROM.
I only read the first line of your problem...sprint to at&t...it can never happen. Sprint is cdma which has no sim and at&t is a gsm which has a sim. You better have insurance so you can run over your now "speed bump" and get a new one.

ROM fine.
Radio ROM = BAD.
RHOD400 and RHOD500 are the model numbers for the Sprint and Verizon TP2s respectively. Other carriers also share these model numbers, but those are the big two.
The Radio ROM you flashed however is for the GSM only TP2, not the combo CDMA/GSM TP2 that you have.
Flashing that Radio ROM was a HUGE no-no. Boom.

You should put a little more time into research before jumping in with the flip comments.
1) Sprint does have SIM cards. I've got one in my hand. (No, they're not used in all phones of course, but Sprint does have their own).
2) The Sprint Touch Pro 2 can very well be used on ATT once it is security unlocked and a patched Radio ROM is flashed. To say "it can never happen" is flat out wrong because it's been happening for a few months.
3) The CDMA Touch Pro 2 models (RHOD400 and RHOD500) aren't just CDMA. They are CDMA/GSM/UMTS worldphones, supporting operation in all three modes.
I'm Sorry Gamescan if I did not understand correctly. Does this mean there is no help? There's absolutely nothing I can do to revert this and fix it?
I really appreciate all the help!!
I wanted to reply to Akademik's comment, but I didn't have time. This is not the first phone I flash, but it is the first CDMA/GSM phone. I know this phone is dualmode, else I wouldn't have bought it to use it in AT&T.
Thanks again!

Can you connect to it via a mtty terminal?
I don't know if the SD card flash method would work here. If it were my phone I'd try it, but if it's not getting as far as the bootloader I think the chances are slim Maybe while there is no SIM card in it, give the radio ROM less to do?
Found some CDMA radios here:

this result is based on shenriquez american flag in his pro. basically saying hes in america using an american sprint tp2 and trying to use american att service.
gamescan, if i said it cant be dont its quite obvious ive done research through trials and also working a phone carrier for 3 years before finding a better job...THIS CANNOT BE DONE. the dual mode in the sprint tp2 is ment for when people travel to europe, they can pop their "european sim" in and be on their merry way. european cell towers accept the frequency of the sprint tp2 and establish a connection. the US towers have "locked out" tmo and att from being used in the sprint tp2. the reason why you found att on connection setup was that your phone was basically saying" yes att is here, but your not connecting". shenriquez i followed the link to the radio you flashed before you got "shut off". you shouldnt have flashed a GSM radio on a SPRINT TP2...you are bricked my dude. you gave your phone a seizure man.

Google mtty (or search for it on here).
Short version it's text based, but it's pretty much the lowest level access that a consumer can get to a HTC device without ripping the sucker open, manually desoldering the flash chip and putting in another.
If you're not getting the tri-color bootloader screen, there is still the possibility of saving it via terminal commands, but it's not straightforward (and depending on what happened it is certainly NOT guaranteed).

Only it can be done.
With the tools mentioned in this here very forum.
Any many people have done it.
Again, you're not doing your research and making claims that are flat out wrong.
1) The Sprint TP2 hardware does support the US GSM frequencies.
2) The Sprint TP2 hardware does not ship with a SIM lock.
3) The Sprint TP2 hardware does ship with the two US GSM frequencies disabled in software.
4) If you pay for the Olinex security unlocker you can easily flash a patched radio ROM which re-enabled the two disabled frequencies.
About the only correct thing said in the post above is that he should not have flashed a radio ROM from a GSM-only TP2 to a CDMA/GSM combo TP2. The two devices do have different hardware so flashing the wrong drivers *IS* a BAD THING(tm).
But, assuming you have paid for the security unlocker, flashing a Sprint TP2 with an updated radio ROM is stupid easy and once you've done that making it work on ATT or TMO in the US requires nothing more than slotting in an active SIM card and switching the phone to GSM mode.
If you don't know the answer to something, please feel free to ASK about it, but don't make unfounded and incorrect statements. When you state an absolute that is false it just spreads misinformation which makes things confusing for other users, especially those new to the device.

Prove your lame theory. Links that sprint gsm will connect to US towers. Even links in "this very forum". Different frequencies dude.
My two cents -- as I am new, too -- but I ran into a similar situation trying to update the radio on my Verizon TP2 due to 1X issues. My phone is unlocked as I was running Mighty but decided to return to stock (6.1).
Note: my SIM is not unlocked. If I understand correctly, the SIM needs to be unlocked to be able to install a radio from a different carrier, like Sprint.
[As a side note: I think these forums use the term "radio" a little too loosely because the program to unlock the phone to be able to flash unsigned ROMs is also called a "radio" unlocker.]
Back on topic: I flashed my phone with and unlocked radio 2.23.00WU and the result was similar to what happened to your phone: it did not turn on, orange light was on.
I was able to flash stock ROM back onto the phone using the USB cord and the phone is back to normal. Even though it was basically non-responsive except for the orange light.
My phone is in working order after the wrong radio incident.
I hope this helps.

If you believe that you're obviously flat out lying when you make the claim of having worked for a carrier for three years, because no one who worked for a wireless carrier could possibly be this ignorant about how GSM works. It's either that or you're purposely posting false information in a lame attempt to screw with the newbies on this site.
The Sprint TP2 hardware supports all four GSM frequencies - 850, 900, 1800, 1900. You can pull up any spec sheet on the model to see that. This isn't exactly hidden information.
Sprint disables the US frequencies in firmware.
If you are security unlocked you can flash one of the two patched radios in the sticky thread in this forum.
http://forum.xda-developers.com/showthread.php?t=578659
Then you toss an active SIM card into the phone and turn it on while in the US. Set it to GSM mode and bam, you're on a US tower.
Your claim is the equivalent of running around screaming "The sky is GREEN because I say it is! The sky can't be blue. That's false!"

The phone needs to be security unlocked to flash a different radio. If it is not security unlocked a unsigned radio will cause the boot sequence to fail. Flashing a carrier provided radio will restore the phone to service.
Security Unlocking means setting the phone to SuperCID. It is different than SIM unlocking.
SIM unlocking allows you to use different SIM cards. It does not allow you to flash unsigned radios.
The Olinex unlocker will both security unlock you (SuperCID) and SIM unlock you (if needed).
if device was security unlocked and is detected by pc, most likely it can be recovered by mtty. unlike my case where device was not sec unlocked but its detected by mtty using usb or serial. bad news is it would be very hard to recover, im doing some jtag research first, at least i found the pins but no pinout.

thats for a radio not rom. find the cdma rom that allows you to use a gsm sim. you cant use the cdma rom over att network...and that link you posted, there are no success stories in it, only complaints. you have no idea what you are talking about. you sit there posting false statements and trying to sound smart with your handy thesaurus. stop posting false statements lame.
I figured I'd ask here. I'm almost certain that it isn't possible at all to do but you never know what the great devs here at XDA has come up with.
I have a HTC HD7s from ATT. It's a GREAT phone in my opinion. Never had a single problem with it; but I did with AT&T. They were just; lacking in terms of anything in my local area.
Now for my question; It's probably not possible but like I said you never know until you ask. I am currently running on Sprint service with my Epic 4G Touch. Love the service as it does what I need it to do (a lot better then AT&T ever did). Now AT&T is GSM if I'm correct and I know sprint is CDMA.
But what could I change my HD7s over to via flashing/custom roms or whatnot. I doubt sprint would even think of being an option; but if there's a way to get it on even a pre-pay service; I'd love to have it sitting around as a backup phone if I ever needed it. So is it possible to flash over my HD7s to any other carriers? I have read that my current phone can actually be flashed to multiple other carriers, but with sprints (decent) service, there's no need.
Thanks ahead of time!
Your HD7S cannot work on a CDMA network (Sprint, Verizon) because it lacks the necessary radio hardware. No amount of flashing can fix that.
If it's unlocked, you can use it on any GSM network, however; no flashing would be required for that. The most obvious example of a non-AT&T GSM network in the USA is T-Mobile. Your phone will work on T-Mobile but won't get 3G due to lack of AWS UMTS support -- in other words, it doesn't have support for T-Mobile's 3G frequency.
If you can find a virtual network operator that uses AT&T's network, then you should be able to use your phone on that network and get 3G. I'm not up on which operators that might include.
The specific thing you need for your phone is a "SIM-unlock" which means removing the restriction that AT&T puts on their phones to prevent using SIM cards from other carriers. Typically, AT&T will remove this lock for you if you ask them, but otherwise there are sites online that can sell you unlock codes or you could try calling HTC.

I bought a used XT897, did the SIM mod, and run it with AT&T, a GSM/UMTS provider. I'm wondering if I can *also* activate it with a Sprint MVNO like FreedomPop or Ting and somehow use both services alternately / at the same time, i.e. like Chinese phones with dual SIM slots. Has anyone explored this?
I'm currently running a 4.2 version of Cyanogenmod, and they split their distribution into separate UMTS and CDMA builds, so I'm guessing I'd either have to alternate between OS backups, or I'd have to simply switch to another distro / the orginal Sprint 4.1.2 Android...

bump for interest
I actually have exactly the same question.
I tried to ask LG/Samsung tech support, but either they really don't have a phone capable of that, or just don't know the answer.
I guess, it may be a matter of software supporting that as some phones (like LG G Flex 2) have radios capable of doing both.
But my feeling the 'stock rom' is only doing it in 'roaming' mode, when original provider can still get some money for the calls.
I like RingPlus and Truphone but I hate to carry 2 phones at the same time. This really sucks.
Anyone knows the answer to this thread's question?

From my experience, you can only switch between CDMA and GSM modes, so only one provider can be active at a given time. I'm using a SIM-modded Photon Q running CyanogenMod 12.1 on Ting CDMA with a FreedomPop data-only SIM card (using AT&T or T-Mobile signals) inserted. I occasionally switch to GSM to use free data on FreedomPop when traveling, at which point my CDMA phone number is essentially turned off until I switch back to CDMA mode.
My guess is that you'd need a phone with both CDMA and GSM radios that also has dual SIM card slots, which, at least in the U.S., would be difficult to find.
hi...not possible...power amp is only one and phone is maded only for one sim work.
Not possible
