[q] flashed the desire sprint radio and prl install

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.

[Q] Don't Use *228?

I just got off the phone trying to troubleshoot voice dropouts on my Galaxy Nexus CDMA and the Verizon rep told me that on a device with a sim card such as the Galaxy Nexus that you should never dial *228. Is this true? Just curious as to why.

that's correct
the SIM is the authorization to the network and automatically updates the PRL to the phone.

Technically, the PRL is on the SIM (it's call the MNC list on GSM-based systems like LTE) so doing a *228 will overwrite the GSM MNC list on the SIM with a CDMA PRL. Fortunately, MNCL and PRL are pretty much the same thing, so the phone will still work, but overwritting the MNCL will apparently cause some kind of problem down the line, which is why they disable you from dialing it directly.

Yeah, I just had to call them about this yesterday because I just got my wife a Rezound and we live in an "Extended Network" area where we connect to Bluegrass Cellular towers. She has no data connection out there and I wanted to see if they could update the PRL somehow while we were outside of the Verizon network, but they couldn't help me out. She told me to take the phone to a Verizon coverage area (30 mins away for me ), pull the battery, pull the SIM card, re-insert the SIM card, then re-insert the battery and boot the phone back up. That's the only way she said you can force a PRL update. I asked about *228 and she explicitly told me to not dial that as it could mess up the SIM card.
Doesn't make sense to me because if the battery is pulled out, how would the phone know that the SIM card was pulled out and/or inserted? How would that trigger a PRL update as opposed to just doing a battery pull and rebooting the phone without touching the SIM card?

AT&T Note II i317 blacklisted/blocked IMEI?

Okay, I have a Galaxy Note II i317, it used to be my mother's until she had a very tiny crack across the screen to which she got a new Note II at the time. I recently decided to try and use the phone with Straight Talk....
A few things I've done/tried...
Putting the Straight Talk SIM card into the phone, reads No SIM/Emergency Calls Only
Changed the Firmware back to 4.1.1 from 4.1.2 and tried to unlock the phone using the unlock code...unsuccessful
Tried Rooting the phone and using TWRP to change the Baseband... no avail...
I guess the main question I have is if I can even do anything at all to use the phone, or would the IMEI be blocked because of the replacement phone?
Any and all help would be appreciated!!!
Thanks!!![/SIZE]

IMEI should not be blocked...(check with carrier to confirm)..
Straight talk is essentially AT&T...but does use a different APN...
And if the SIM is not provisioned for use by your carrier...the phone will show the inactive SIM message.
Once you have determined the SIM is active and correct...you can set up the new APN in your mobile settings menu and be good...
Give them a call and they can help...
You will likely need a new SIM CARD....g

Should I call Straight Talk, At&t, or both? I know the SIM works in my S III currently. I just really don't want to let this phone go to waste.

Give straight talk a call first...as they provide the service..g

Having trouble with Sprint Note 4 Activated on Boost

So my girlfriend has a Sprint Note 4 she activated on boost. We called customer service, had the phone added, he gave us a ## code to activate and everything seemed to go smooth. Phone rebooted a couple times and then popped on with Boost splash screen and the whole nine, cool we figured all was well.
Issues we started to have are two fold, sometimes she can't send text messages. Phone calls seemed to work fine no issue.
The other issue though thats more concerning is the phone doesn't seem to want to establish a 4g connection, when the phone boots its unable to download a firmware upgrade(which I'm assuming is from boost?) and we get the message "unable to establish reliable data connection" but 3g does seem to work. Because of this it was unable to "update the boost server(or profile)"(I believe thats what the message said)
I'm a VZW retail salesman and this issue reminds me of a sim issue I've seen a couple times, but all we did was pop the sim from her old LG Stylo into the note, anyone have any ideas?
I'm wondering if it's an APN issue, but this sprint note 4 on Marshmallow doesn't seem to allow access to edit the apn.

Note 4 on Boost Mobile
Hi!
I just did this. I switched from VZW to boost a month ago and since no boost phones are beefy enough for my regular usage on mobile devices I got a used note 4 and went to the local boost store to swap it over, I called and tried to do myself calling CS on the phone or website and failed. Paid the $10 and everything is working fine. I think since you got the new boost mobile boot animation you should be fine.
When at the store the lady told me the phone NEEDS the SPRINT sim card and maybe part of the reason I was having trouble was due to me trying to use my original boost mobile SIM card.
I am sure your aware but this is the disclaimer from the boost mobile site at https://www.boostmobile.com/#!/support/faq/phones-devices/activate-a-sprint-phone/ ....
"Voice, basic text, and web will be available on eligible Sprint phones.
Due to technical differences between the Boost Mobile and Sprint MMS platform, we CANNOT guarantee that MMS (aka picture messaging) will be available on these phones. In addition, we do NOT guarantee that all Sprint specific or other preinstalled applications may be available or functional (e.g., Sprint TV, Nascar, Sprint Football Live, Sprint Navigator, Mobile Wallet, Wireless Backup).
NOTE: If your Sprint phone asks you to check for Wireless Back up Availability, select No.
Instant Messaging and Mobile Email services will vary by device. For email access, customers can enter their email client's URL into the web browser.
"
You said sometimes you can't sent/get text messages(which implies SMS), did you mean MMS(picture, video, messages with subject lines, group messages, texts longer than 160 characters, etc) ? No SMS would be activation issues, no MMS sounds like APN issue.
I'm no SIM expert, but my understanding is, for CDMA/LTE anyway, that APN settings are applied to the device from the SIM card. I assumed the SPRINT device on Boost would just use all boost apns like my boost device did. However when I compare my boost mobile device APNs and my Sprint device (on boost) APNs they are slightly different.
Maybe try using the original SIM that came with the Note ?
My APN on my Sprint Note 4 flashed to Boost Mobile are;
Bah... I can't copy paste, how about I take some screenshots and also attach my APNs config XML ?
To edit APNs, from the dial pad enter ##3282# , you will need the MSL code.
Hope you get it working.
Anyone with insight for using Sprint stuff on Boost your additional insight would be appreciated.

Oh, you can also try this as well,
"Refresh Customization"

I did mess around with some stuff trying to get roaming to work and this app automated the programming and activation processes to bring me back to original (boost mobile) settings.

Help with unlocking what carriers I can use with the Sprint HTC Evo 4g

I'm sorry if this is the wrong thread to ask in. I'm really new to cell phones and sometimes have trouble. I have an HTC Evo 4G that's locked to the Sprint carrier. We'd like to try and put this on StraightTalk. StraightTalk's bring your own phone's website asked for some number on this phone, we entered it, and it showed the phone would be compatible with their network. If this is wrong, please feel to correct me.
I've successfully unlocked the bootloader and installed Revolutionary on the phone. I turned the SecureBit off (S-OFF). My understanding, even though this phone doesn't have a SIM card slot, the SIMLOCK feature in the HBOOT menu is a way to enable this phone to use other carriers, such as straighttalk. I believe this phone is considered a CDMA phone.
I've generated a Config.dat file using the IMEI number and put it on the root of the MicroSD card. I enter into HBOOT and select SIMLOCK. It reads the Config.dat file and then stays at Wait for AMSS Ready...
I've waited a good thirty minutes or so. It just stays there. So then I hit the power button and it gives an error message about not being a key-card. We thought if we were successful at the SIMLOCK screen, a menu would be available on the phone (once we booted into the OS) that said something along the lines of APN (Access Point Network I think), where we could add the Straight Talk stuff...
I was thinking I might be on the wrong track and might need to somehow add Straight Talk PRLs, but I'm not certain if that's right or how to go about doing that.
Is there a way to "unlock" this phone so I can put it on the Straight Talk network or any other compatible network?
I'm sorry if these questions seem really basic. I've tried searching the internet. I've found lots of videos on how to do this, but they all involve using a SIM card from another network. They even claim they're for the Sprint HTC Evo 4G.
Any help would be greatly appreciated. Thank you.
