I successfully flashed the CDMA Desire with a Sprint Radio off the Evo. It's baseband 2.15.00.09.01
I also installed PRL 60677 from sprint. I also tried the Cyanogen MOD.
It's currently running the alltel ROM so I can get access to the dialing codes in the PRL but even though I flashed the RADIO and the PRL it still shows the network as alltel and it won't let me get access in menu>settings>Wireless networks>mobile network
I can turn it on. But it either seems to take a long time to turn off, or go off by itself, not sure which. But once its on it is greyed out and won't let me get access to it.
I thought maybe it was the PRI, but I don't see how that could be. Is there some sort of Initial Program Loader from alltel doing this can someone tell me why it won't pick up on a sprint network that I have for cdma like connecting or sharing a connection etc... and won't get off U.S. Cellular network?
I might just try flashing to verizon and see what happens just to observe. It should be a lot easier than flashing to sprint.
edit: I did change all the dialing codes to sprint in the ## menu btw. I used the codes from another sprint Phone.
EDIT: It also won't turn off always when I hit Airplane mode and constantly says "Turning on...." and won't give access when to "Mobile Network" when you hold down the power button and that menu comes up.
I used the original Stock RUU to switch back. It changed the baseband and everything else back and also got rid of my clockwork recovery in the process
The only thing it didn't change is the PRL. I had to redownload that and manually rechange the codes in the ## secret dialing menu's.
As far as I understand I will need to change the esn or have this esn to sprint to be able to get it working on a sprint network. It is very difficult thing to do so I will have to postpone this. I'm thinking there might be some code or something in one of the abstraction layers or HAL layers that is preventing you from changing the esn somewhow... not really sure but that seems like the best place for me to look as it is the interface between the software and hardware. The hardware is there and able to do it, so it must be the most basic software or HAL that is preventing me from doing it I am guessing. BTW this is not illegal. I own my phone. If anything it's illegal for someone to sell me crap that doesn't work the way it should because of bogus programming that's been put on my phone to prevent me from using it! And nikola tesla invented the radio btw where is the money and credit he deserves for this?!
Hey man,
I am trying to do something like this for my wife. I'll let you know how it goes once I get the phone. In the meantime, maybe this might help you?

I know it's not quite the same - taking VZW phone onto Sprint Network, but I thought it might help you out.
I'll post my experience later when I get the phone next week.
Thanks,

I don't think that's quite the same thing. I read through the post and a lot of it didn't make a whole lot of sense. Generally you have to have a compabible esn with the network you want to use. Every carrier has a database of all the esn's that are registered and available to use their service. If you try to connect to their service their software will recognize the esn as false and not grant service even if you install all the correct radio's/basebands, PRL files, Firmware, etc... it just won't work because you don't have an esn in their database so you have no authority to connect to their network. So you have to change the esn. But it's not such a simple thing to change an esn. I'm guessing its written in hexadecimal somewhere in the registry, but maybe not. There are certain command sets like the Haye's command set that only apply to CPU or other hardware like modem/Radio. There is an RIL which communicates between a driver, the modem/radio, and the OS. I'm guessing the esn is communicated and retrieved by the RIL layer that communicates via proxy & a driver or in one other PPP protocol that apparently only communicates with the network at certain times suspiciously. That's because the ESN is apparently located in the radio/modem and people have successfully changed their esn by changing their modem and installing a different one. A modem is essentially an ultra small electronic radio. In the same way that a radio picks up signals out of the air and converts to sound, a modem picks up signals also and can convert to sound as well as internet data, text messaging, etc...
If your radio doesn't have the proper command sets it can not pick up on certain signals such as for example sprint 1900 MHz for a sprint radio/baseband version vs a 900MHz signal for a 900 MHz Verizon. Each carriers software might be set up to block the other carriers signals in certain ways. For example each carrier has roaming agreements with the other carriers so that when you go out of your host carriers network say from Verizon into Sprint then you can "roam" and still get coverage. Sprint in this case provides the coverage and therefore they have an agreement to use each others network to provide better coverage. They may also pay each other small fees to use their network. Roaming, carrier type, cell number, mobile network operator, ip addresses, etc... can all be preprogrammed into CDMA handsets through ## secret dialing modes. This only works on CDMA handsets or in CDMA mode on your phone (i.e. not GSM). Usually on HTC devices you press ##775# to update a PRL file which is the Preferred Roaming List. That is usually easy enough, but this may not always update all your phones programming and you may have to do so manually through other ## dialing codes such as Primary HA secondary HA MCC (Mobile Country code) MNC (Mobile Network code) etc... Even if you do all that though it serves no purpose if the esn isn't registered to the network that you want to use. Generally only Cricket and MetroPCs in the USA will register a CDMA esn to use on their handsets. All the other carriers like Sprint, Att, Verizon, etc... generally won't do it, hence you can't get CDMA service from them if you have a CDMA capable handset even if you update all of your files as there is a program that is run on behalf of the carriers that manually checks your phones ESN/MEID/etc... to see if you have the "proper Credentials" or authorization to use their network. In this case the authorization is given on whether or not if your ESN is in their database and that it aslo can be in their database but blacklisted or grey listed in the case of you have an innactive account and need to pay them to get it "white Listed" or if you have a debt on your account or the phone is reported stolen it may be "black Listed". Usually you can flash to Cricket or MetropCs fairly easily though and they will even do it for you for a small fee.

Has anyone been able to modify the MSL on the Harrier/PPC6600/XV6600 yet?
My unit was on a prepaid Sprint account and I would like to activate it on a Verizon account.
Thanks!
I can change the MSL on the Harrier.
however It may or may not work for you, I dont think Im allowed to post that info due to confidentiality stuff.
so dont pm me, and I wont reply with something to try.
cheers.
:wink:
I have the same issue. I have a Harrier/PPC6600 from Sprint and I want to use it on my Canadian CDMA provider. My provider will not have a problem with the ESN# being clean, but the phone needs to be unlocked to use their PRL. I'm checking with the carrier to see if they can do it or if they purchase their phones elsewhere. If the carrier can do it, great - otherwise I also need a way to unlock the phone.
Thanks

see how rhauff gets along,
if it works for him im sure he'll be able to point you in the right direction.
the other thing to try is a bit of social engineering and ring sprint, ask to speak to there Corporate team and just explain to them that the company you work has a couple of harriers and you want to swap the numbers and could they please send the reprogramming details to you via email,
then explain you will ring the back as soon as the devices get to you (as they are currently in transit) and once you have changed the numbers on them.
it will work.. trust me.
Inane, you are just full of good ideas! I'm still waiting for the battery so I can try the reprogramming, it'll probably be next week before that happens. I will let you guys know how it works out though!
Finally got the batteries last weekend, ordered them from 2mangoes on Ebay and got them direct from China! They seem to be good, perfect fit and last about as expected.
Thanks for your help inane, I did use the MSL access code quite a bit. I think it is safe to post here, I have seen it listed, have not seen it forbidden and it is all over pdaphonehome.com.
Here are my result, this is a copy of my post on pdaphonehome.com:
Well, I had searched and didn't find any success on this. I posed the question hoping somebody had solved this but hadn't posted it yet.
Anyway, I was able to switch this over (only partially at the moment!) using the existing Sprint MSL. A Verizon MSL of 000000 would only be required to do OTA programming (PRL & network info).
My procedure was as follows:
1. Program the PPC6600 with Verizon's radio ROM to support their EVDO PRL.
2. Using ##775#, load Verizon's PRL 50430.prl.
3. Using ##MSL#, change Mobile number (MDN) and MSID. I used my mobile number as the MSID, which I think is correct.
4. Using ##778#, under MSL settings, I changed the SID/NID to 26 which is Verizon's ID for the Mpls/St. Paul market. I don't know if this step was required. As I understand it, Verizon may ignore this, not sure.
Ok, that's pretty much it. Called in and had the ESN activated on my account. They REQUIRED me to put a data plan on, I went with the $0.015/Kb.
Anyway, outbound calling works fine, but inbound lands at my voice mail. Txt messaging no go yet, and no Internet. I did enter my username [email protected] and password=vzw, and set DNS addresses, but still need to get a proper IP for PHA and SHA (still have Sprint's numbers).
Any ideas on what I need to change to make inbound calling to work?
EDIT*************************
OK, solved the outbound (long time ago, actually). I set roaming to HO, home only. Now in and out bound work great. I got data connection working by setting, under 3GDATA1, to "No IP".
i-mate pda2k evdo
How about i-mate pda2k evdo, is this setting work fine on this PDA?
Sorry, can't help you with that. I've only worked on the HTC Harrier.
After you entered the ##775#, it asks for an unlock code. Where to you get the unlock code it is looking for?

Can anyone give a step by step to unlock my i-mate PDA2K EVDO. Model No. PH20A2.
I just moved from Australia to the USA... I love this phone... it keeps me so organized... I just want to keep it to use on the USA CDMA network.
That would be such a help.
After switching my PPC6600 to Verizon, it mostly works, but a couple issues remain.
First of all, here is what I have done:
1. Loaded Verizon's firmware, which changed the radio and Ext ROM.
2. Switched SID/NID to a Verizon number.
3. Loaded a Verizon PRL.
4. Entered proper MDN and MSID.
Here is where the ghost remains:
Under Roaming, there are Home Only, Sprint(!), and AB.
Why doesn't that say Verizon now? Also, if I tap the Antenna symbol on the header, it says Sprint PCS!
If I set roaming to Home Only, I can make and receive calls & txt messages.
If I set roaming to Sprint, I can place calls, but incoming go direct to voicemail.
Also, my data connection does not work (CDMA wireless) and I have a hunch it's related. It dials, but then says "The answering modem has disconnected".
Any ideas? Thanks!
Got data working!!!!!!!!
Under 3G Data1 I switched from "MIP Pref" to "No IP" and now my CDMA data connection works! I am getting only 1X speeds (100-120 kbps), so now I need to find why EVDO isn't working (I'm pretty sure we have it here).
Still can't figure how the Sprint labels show up after I flashed all the ROM's though!
I love this idea; please consider making a HOWTO for this.
I love this idea; please consider making a HOWTO for this.
I am weary of Sprint and envious of EVDO for the BlueAngel.
Could you document what you've done so far?
EVDO different carrier
Same problem, trying to make work verizon on mexican Iusacell. 1x works, but when trying setting MIP Only or MIP Preferd, i get "No modem at abothe number" I tryed all the roms I found on the net, nothing works. There MAY! be some aditional ROM storing phone settings like number, passwords, SID, MIN and all the settings refered to the data & Phone.
With Samsung i730 i Tryed QPST, but it doesn't recognize 6600, any 1 Know about som software capable to conect to the phone???
you are using a HA01 "EVDO" radio rom correct? latest version i've found is HA01-156
I like to use phones that tmobile usa doesn't carry because my internet plan will only work with normal phones and phones that tmobile doesnt recognize. Well, I'm using a tmobile dash right now cracked with kavana's rom and I'm wondering if I can change some system information in it that will make the network think that it's another unrecognizeable phone.
Does anyone know how I can do this?

Well let me see if I'm getting what you post....
You are basically asking some "magic (app)" so that T mobile doesn't recognize the actual dash. Not recognizing other phone will avoid paying more for your plan right?
This is what I called "Illegal polite undercover fraud request" from my point of view or I'm wrong ? This is not allowed here dude,
There is simply no way of cheating here. The contract (or payment) is identified by the IMSI (SIM Card) - not the device (IMEI) - and the traffic is identified by the APNs you set (GPRS settings). The IMEI of the device is completely useless in that regard.
You cannot cheat - that easy.
Operators are sometimes linking web-applications to the IMEI identifying the device type to optimize services in a device specific (e.g. MMS) way.
Changing the IMEI is simply
illegal
very hard to do and you will not find any service that will do it for you, neither at XDA-developers nor at those sites that deal with SIM Unlocking. They have the best knowledge of how to deal with the encrypted areas that safeguard the operators settings linked to the HW of the device.
If you could succeed to "fake" the IMEI to be of another device-type, some services that depend on the correct evaluation of this (MMS, other services) mail fail on your device because they do not match the real needs of the device.
If operators detect bogus IMEIs in their network, they may simply refuse to serve this device and you cannot log into the network any longer.
Spend your efforts on something more useful than trying to cheat the operator.
ok for the simple fact of using my brain and knowing how any computer system works.... yes. yes there is a way to make ur phone appear to be another its just not an app, it has to do with someting alot deeper... but that thats all im saying it is possible but immoral im sure.

Anything is possible if you pay the right people. Knowledge how to change the encrypted block consistently is rare and kept secret as those guys build a business around it.
But changing the IMEI is so useless imho - why waste time doing so? Especially as it will not even help you to get free calls or data transfer.
i know what OP is getting at. its similar to tzones. just go on to your tmobile account and change the phone to an old one that uses tzones such as the razor, if that doesnt work try going to a store and asking for that service by showing them an old phone. after the service has been activated all you have to do is change your network settings (internet2.voicestream.com) it worked for me for years, but sadly moved on to android which uses a 3g network. good luck.
Yeah - that's what I say:
you can configure services that are used on the network
but you cannot hide the device you are using from the network itself
Any messing around making things seem different than they are will get you strange behavior of application services - but it will not save you any money.

This an "APN" I talked about earlier. Operators have several for different intended services (e.g. internet), but they try to keep things simple and reduce the amount of APN recently (so finally you have only one).
Per APN (Access Point Name):
The IP routing may be restricted (e.g. only to the mail server)
Charging may be different (kb/$)
The use of certain APN is restricted to you user profile, i.e. not everyone can use any APN
Depending on how strict the operators are handling the last point and how close they observe the generated traffic per user you may occasionally be lucky to sneak through with your traffic.
Mind however that for all traffic the operators are logging the IMSI (SIM Card) that generates it - so also for prepaid cards it may suddenly happen that your money is gone for old bytes that have been found linked to your SIM.
Hi, i just bought the phone off ebay about a week back.
through a contact my dad has in Reliance(carrier in India), i have somehow manged to get my meid registered., the phone has been rooted and is running stock sense 2.0 ROM. every time i go to wireless&networks and set the network selection to home only, i get no signal. putting it on automatic gives me a roaming sign on the network bar. dialing *228(while roaming is on) brings me to a reliance answering machine(?). after choosing my language, it tells me that my phone could not be activated.
please help. many people have manged to do this but im not getting any response from them.
thanks, Sid.
Dial ##778# and change settings manually. The code is 000000. You will have to change Home SID to the SID for Reliance and change MDN and MSID. If your old phone worked, easiest way is to change the settings to match your old phone.

I've tried dialing ##778#, but nothing happens. just takes me back to the dialer. should i change my ROM?
How about ##7764726#?
If neither will work, you might have to flash to a stock ROM. Both should definitely work from a stock ROM.

just recovered the stock ROM and ##778# works! ive also manged to get the prl from my carrier, but i dont have my old phone. i can probably arrange the the MID no.s etc, though. Also, i dont have to change the ESN, do i?
I think these are the things you will have to change:
MDN is your full phone number including area code. In the US, this is 10-digits.
MIN1 in the US is typically the 3-digit area code.
MIN2 is typically the 7-digit local number.
MIN1 and MIN2 can be different than the MDN, but that's very rare and usually only happens if you've had a phone number change.
MNC and MCC will need to be changed for your country.
MCC+MNC+MIN1+MIN2 = IMSI, which is the the subscriber identification for your cell provider so you need to get those 4 settings correct.
Home SID will need to be changed to Reliance.
I think MCC, MNC, and Home SID you should be able to get from any working CDMA phone that successfully connects to Reliance. Maybe get it from a friend or family member's phone. MDN, MIN1, and MIN2 should be the only things unique to your phone.
No, if your MEID is registered, you don't have to change it or the ESN.

hi this is vivek i also have a droid and it also has the same problem but the meid is not registered and it is rooted and has a stock rom but when i dial ##778# it juz come to the dailer so what shud i do pls help me out
MEID will need to be registered. There's really no reason to proceed if it's not, because the network won't see your phone.
##778# sometimes doesn't work on my phone, I often have to reboot it and immediately try ##778#. Oh, and you have to hit Dial after entering it. It will ask for a password, and that's going to be 000000.
However, without having your MEID registered, you won't get anywhere.

hi, make sure you get the a key. im having trouble getting that. last piece of the jigsaw i guess.
Usually a fresh activation doesn't require an A-Key, but if you change MDN/MSID too much, it'll trigger a security lockout in the fraud detection system, and then you will need the A-Key to reset it.
I don't know how it is with Reliance in India, but with Verizon in the US, you have to call a higher level tech support person to get the A-Key. One way to get around that, is to have the ESN/MEID on your account changed to a different device, and then change it back.

How I change verizon carrier from my mobile to any Indian carrier
Dear ,
I had buy mobile online from Ebay, Unfortunately I did not read the feature properly and now mobile is arrived. This mobile is CDMA and it contain Verizon network which does not work here. Now I have to change this network to any Indian network.
Please suggest who will help to change this network. How to process this. If it is chargeable then i am ready to pay charge if anyone can help to change this network

hi . ..
i was just wondering if it can be possible to use a
verizon a 855 (without sim) cdma phone in india???
we have cdma networks here ,but not very sure if they
work without sim on a BYOP thing. ...
After many unfruitful hours on helplines both carrier (TracFone) and Google helpdesk I thought maybe there would be some help here from a person who knows more than a diagnostic tree book. 4G voice just quit, wont dial even, just immediately says call ended. 3G still works and they both still do data. I've reset, cleared cache on phone app and connectivity services, restarted, airplane on and off, basically everything I could think of short of a factory reset.
I think this is the most significant thing but it was disregarded by all call operators: I swapped the sim with my wife's phone and it didn't help.
To my limited understanding this made my phone hers in the eyes of the carrier.
So I felt that this eliminated the carrier as the fault, unless they have some file that says don't allow 4G voice on Pixel 2xl's.
The only other thing I can think of beyond some Google conspiracy to make me buy a new phone is the Qualcomm com chip 4G voice parts have quit.
So anyhow I throw myself at your feet and hope someone has some knowledge or experience to relate.
If I could afford a new phone I'd just dump it.
Thanks!
Does your wife use the same carrier as you? If yes, can you try a sim from a different carrier? Did your sim work in your wife's phone?
> To my limited understanding this made my phone hers in the eyes of the carrier.
Not quite. The carrier can still identify the phone by IMEI.
> unless they have some file that says don't allow 4G voice on Pixel 2xl's.
Actually, the carriers often have lists of models that they white- or blacklist for VoLTE. And the phone's firmware must contain the correct configuration for VoLTE on that specific carrier. But it's unusual that it stops after having worked.
> the Qualcomm com chip 4G voice parts have quit.
I don't think there's much hardware involved that isn't also used for other things. A hardware problem seems very unlikely.

TF went over the IMEI several times and said it was cleared for 4GLTE.
The problem was solved by moving to Mint, not only do I again have VoLTE but the call clarity is incredible, I actually had to turn down the volume.
I filed with the FCC and started a chargeback with VISA against TF.
Thanks for your reply!
