[Q] SPH-L900 radio to SCH-R950

I understand that there are some hardware differences between the Sprint SPH-L900 and the US Cellular SCH-R950 such as the lack of sim card slot on the Sprint version.
Let's say I had an SCH-R950 and wanted to convert it it to use on the Sprint network. Forget the ESN issues. Can I simply flash the SPH-L900 radio to the SCH-R950? Are there any other hurdles to jump?

no you cannot do that. to get on the sprint network you need to add your esn and other info to their network. which they don't allow. so flashing a radio will do nothing besides mess up the phone a little just wanting to switch services i take it? there are a lot other networks you could get on.

I mentioned I was aware of the esn issues and to forget them.
I'm not concerned with making phone calls or having data just yet. Can I make the phone a Sprint phone? Accept Sprint updates, show the Sprint logo on boot up, see the Sprint network, etc?

i know you said it but... never mind
you can make it a partial sprint phone haha. here's what you can do. you can run the latest sprint LK8 update. you can show the sprint logo on boot up/shutdown. you can see the sprint network with a prl change. so basically you can do everything except logon to their network for data and voice calls. there's no way to get your phone on their network other than roaming from uscc or another carrier with roaming agreements with sprint. unless you do some unmentionable illegal activity.
if you want to get the sprint updates on your phone you will need to root and install cwm. come join us over here http://teamuscellular.com/Forum/forum/299-samsung-galaxy-note-2/
i can assist you with getting this all on your phone.

On my way! Thank you!

Someone help!

Sooo...I have a US cellular note 2...what fun things are you trying to do with yours? I'm merely looking for a sim unlock. ..but now I am curious

Well technicaly speaking, I guess if you can get recent PRL and Profile from Sprint and see there network, yiu could possibly change your IMEID / MDN to am existing phone from sprint "kinda like cloaning" and it would work. Your phone would just register on the network as whatever IMEID/MDN the phone was. Data would be available as well as voice.
Just speculation.

I am not interested in cloning at all. All I want to accomplish is exactly what I originally posted. Can anyone help me with that?
I need the PRL and Profile.

Didnt say you wanted to cloan. Its just kinda how the proccess would work lol.
Anyways, might wanna hit up a kernel dev, its going to require some base level work. I would say try flashing a stock kernel but you would risk a brick.

flashing their radio and kernels will do you know good. especially the kernels. you just need to get into the programming menus of the USCC phone. i've yet to find the codes for it. :/

[Q] ATT Roms on T-Mobile network?

I currently have ATT service with my S3. I'm running the Intergalactic 3.0 at the moment and I absolutely love it. However - I just switched to T-Mobile. I want to keep my current phone and sell the free S3 they gave me so I don't have to deal with losing any information or anything like that. Can I get away with this on the ATT based ROM? IIRC T-Mobile and ATT run on very similar networks/frequencies. Any advice would be helpful here. If worst comes to worst and I have to use the T-Mobile provided phone, can I flash Intergalactic on it as well or do I have to choose from the T-Mobile ROMs on this site?
Thanks to everyone in advance.

You should be able to add the proper apn for t mobile. You also may want to flash one of the t mobile radios.

Strange. I unlocked the phone, I was able to put in the SIM card and the APNs filled themselves. I was able to make calls and texts but unable to use internet. Any idea here? Using Intergalactic 3.0
To clarify - no internet at all. No Edge, GSM, or LTE

Strange. I went back and re-registered on the network through the settings and now it's getting 4g, just no LTE. At least it's working though!
Edit: Kinda. It worked for a minute then I locked/unlocked the phone and it didn't want to work any more.

[Q] Can I use AT&T i747 on Bell in Canada?

I have an unlocked stock rooted AT&T i747 running 4.1.2. I want to use it on the Bell network. When I put in a Bell sim, it shows it has service, and the pda.bell.ca APN shows up, but it can't find the Bell network, only Rogers. Just wondering if anyone else has tried the same thing and had success or no? As it is I cannot call, text, or browse... Please let me know if there is anything I can do.

Is there an option in the network settings to select lte or wcdma?
Did you check to make sure the phone isn't listed as being blacklisted?

I haven't located any settings about WCDMA or LTE. On my i747m I'm used to being able to toggle between 2G/3G/4G. Nothing like that here. Bell's IMEI check approved it, and it's not on the national blacklist.

Getting service but no data is usually just not having data turned on.. So obvious question: Do you have it turned on in your settings/pulldown menu?
If your APN checks and data is turned on, you might have to give Bell a call (don't have to tell them you have a US variant).

Thanks for your input. Data is definitely turned on. However, please remember that it's not only data that isn't working. I am also unable to call and text.

Can you check to make sure your baseband matches your bootloaders? If it does, I'm out of options for now. Bell (or someone else) can probably help you further.

Sorry for not being overly knowledgeable...

It seems it should be that way... the phone is unlocked, but when I put a Bell sim in it it says emergency calls only. The only network that comes up to set as default is Rogers. Can you advise me as to how to make 100% sure the phone is unlocked?

Which carrier are you trying to use the phone with? If it is Telus/Bell/Koodo/Virgin, it should work without changing anything.
The only networks that support GSM are Fido and Rogers.

The ATT should work on Bell and Telus. My Bell i747m could roam on ATT when I travelled to the USA.
Just to confirm: you can connect to the Rogers network but not Bell or Telus?

Now data after returning to stock

Ok so I had to reactivate my Z2 Force Sprint., and after set up I do not have any data. It show 3G then LTE then nothing.. I tried flash all twice, but still can't get full data.. I was on Lineage, but went back to stock as I was going to sell this phone.. but now I'm not sure how to proceed. Any ideas will help thanks.

I'm in the same situation, update from nougat to Oreo and I ran out of mobile network, if I find any solution, I'll let you know.

Sprint is suppose to be sending me another phone. Will see, so I went and relocked the bootloader.. At this time I don't care if it is stock or not.

I went to Motorola to get the factory images for this phone, can't seem to find any.. funny with bootloader locked, I get a message, that a different software other than factory installed on phone.. How, when I flashed the flashall that is suppose to be 100 percent stock.

Found out what appears to be the issue.. Up at Sprint, my ICCID (sim) Doesn't match what's in the phone.. Why I do not know.. I gave them two other sim cards, and they claim they are not compatible but, one is the original one from the phone.. So tomorrow I have to go to Sprint and get another.. To add insult to injury, the Galaxy S6 I purchased, and billed as new.. In fact is not new, was a refurbished unit.. Ok, but the mic does not work.. Went to Sprint to get it replaced $75, but because it has a after market screen and not original, they won't touch it.. Again, no mentioned at time of purchase.. Luckily for me I'm getting my money back on it.. Talk about a bad day, and a couple of effed up phones..

Did Lineage OS work?

Sorry, I need to clarify. Alot of Moto Z2 Force users have issues using their "unlocked" phones on compatible carriers. For instance, I have an unlocked Sprint Version of the phone, yet cannot use it on the Verizon network (even though both phones have compatible hardware). So there must be a glitch or Carrier lock in the phone's "Software Channel" preventing people from using their device on other networks (aka: have their phone unlocked).
Did using Lineage OS allow you to use your phone with whatever carrier (SIM change) without any modification besides the OS?
Please let me know if I need to clarify any further. Thank you!
Get Verizon Network to work on your Sprint Moto Z2 Force!

Sorry. I did not use my phone on any other carrier.. But I believe this phone you can use on T-Mobile, Cricket or even AT&T.. Providing it is also GSM compatible.. A buddy of mine recently left Sprint, and has a Iphone 7 and he went to Cricket.. Best move he every made.. And not that the GSM is unlocked he can talk, and do internet without issues. I hope this helps. I also now have a LG G7 ThinQ as I was having issues with LTE and Call issues, and Sprint sent me that, and I sent then back my Moto Z2 Force.

Verizon is the only carrier you can't use. Verizon is a CDMA carrier. They must have your IMEI in their database to get calls, sms, MMS, etc. AT&T works, T-Mobile works... They are GSM so as long as the phone can connect to the towers, they don't care really.

Verizon is ALSO GSM and 4G LTE...and switching over to 5G. Strange thing is, when we initially got the Sprint phone and put in the Verizon SIM card, the phone actually recognized the Verizon SIM and all data, network, and calling WERE working, without having any dialog with Verizon (ALSO: without the phone's IMEI number on Verizon's database). It wasn't until the phone was updated to a more current Oreo Operating System that the SIM card wasn't recognized. Leading me to understand/believe that THERE DOES EXIST a ROM that allows a Sprint Moto Z2 Force to work on the Verizon network...just a matter of finding which one.
Also, when we installed Lineage OS onto the Sprint Moto Z2 Force, the Network options actually ALLOWED us to put in Access Point Name (APN) fields, but prevented us from saving them, saying user access denied (Rooting the phone may allow access to these settings?).
Also, once Lineage OS was installed, the Network could be taken off from, "Actively Connect" to a network and re-directed to a Carrier specific Network...Verizon being one of them, yet when doing so, we received an error message, "SIM card prevented linkage"....This we are assuming IS an issue with the IMEI (???), yet the IMEI # is different than the SIM #.
We currently are trying to work with Verizon Wireless to alter their, "Bring Your Own Device" settings to see if they WILL ALLOW a compatible hardware phone to be added to their platform by adding the IMEI to their database...
Still trouble shooting and fingers still crossed...
UPDATE:
Verizon working on Sprint Version Moto Z2 Force via Oreo OCXS27.109-48-3 (NOT listed in Motorola mirrors lolinet firmware page). We suggest doing an install of an older version of Oreo (i.e., OCX27.109-48 from 3/2018), then a "Motorola System Update" will pop-up suggesting you to update to version Oreo OCXS27.109-48-3...once install has completed, pop in your Verizon SIM card and voila! Network connection, data service, hotspot, & voice calling all working!
Now the key is to NOT do any future updates and disable the app "System Update" and force stop "Motorola Update Services" (if rooted, disable it!).
We're still working on what Sprint Applications can/need to get disabled, as notifications for "Mobile ID and "Mobile Installer" are still on the pull down notification screen. (Rooting most likely required for these).

Question Desperate help needed Z Fold 3 SM-F926B. Cant use any sim.

Need some help guys. I am based in Australia and swapped an iPhone for the Z Fold 3. Went through the usual connection process with my sim and esim whilst connected to wifi. All was well as it allowed calls and received calls when I was home. As soon as I stepped outside my home where it was trying to use the network, it does not work. It keeps saying not registered on network. Tried to manually select network via settings, checked all APN settings from the network and all is ok. Even tried 3 different carrier sims (Vodafone, Optus and Telstra) yet still no matter what this phone will never connect to any carrier network without wifi. From there I tried 3 different firmwares from Sam mobile just in case it had corrupt firmware. Both android 11 and 12 will not work. Need help guys please. Any suggestions?

Did you try calling the carrier or going online to their site and activate the phone? Not from Australia but I think it's worth a try.

Hi there. When I first got my unlocked phone and put in my Verizon sim, it worked right away. However, when I logged on to the Verizon site, it was showing my old phone with the new IMEI and the phone could receive calls but not call out. I called Verizon and asked them to activate which fixed the issue. Can't you call the carrier and ask if they can help you figure out why you can't call when on the cell network?

That is the same error I get here in the States if I try to manually connect to any roaming network (network other than T-mobile, the carrier I use).

It works on T-mobile, but it refuses to connect to any other network, and if I try manually to switch, it gives that same error message you get. Roaming is included in my plan for calls, text, and data, so it is supposed to work, but these phones have issues. I currently have the temporary fix on my phone for the T-mobile issue, so it has stopped flipping to "Emergency Calls Only" and back, but the fix prevents it from seeing other networks now. Whether it is Samsung or T-mobile who has to fix it, it needs to be fixed!
