I'm trying to get my SM-G935V to work eventually work on Sprint. I already flashed my firmware over to SM-G935U. However, the Sprint IMEI check says it won't work on their network. At a Sprint store, the rep won't even try at a store to test out a Sprint SIM to see if it works. Would a Sprint SIM work in my phone before having my IMEI whitelisted (if that's even possible)?
My second option while waiting was to use Red Pocket. I got a plan, I got a SIM card, but I got "Error! Activation Error We are sorry, but due to the rules set by our underlying carrier, your phone number cannot be activated on our CDMA LTE service."
The third option was trying to change my IMEI which appears still legal to do in the US, but not possible to do on my phone because it won't bring up Engineering Mode with the codes. My thought was it was because my CSC still shows as VZW. I thought G935UOYM9CSC2 was XAA originally but I can't get that to show up.
Any other ideas on getting off Verizon with this phone?
Flash the Unlocked firmware on it. You will have to use a modded Odin, see the appropriate thread for that.
However, it will not change the IMEI. If the phone is currently locked in a contract... there is no way around.
Changing IMEI is illegal and will cause problems.
I had never switched my SIM card from the Verizon network to another one until today. It reboots into recovery and changes the CSC. This is after flashing to SM-G935U firmware. When I was on the VZW CSC the secret codes (USSD codes) wouldn't work. After swapping in an AT&T SIM card, the codes now work. Red Pocket white listed my IMEI no problem. Now if I can get Sprint to do it...

Hello, the phone on firmware APF2. Menu there are no hotspot. My opeator not a sprint, your phone is connected to another operator. Sim card and not a sprint, and from another operator.
How to make a hotspot to display the menu?
Well, from that message it sounds like your SIM card is not a sprint one. Who is your service provider? If it not sprint I would suggest using the unlocked firmware G935U. If you are with sprint I would try possibly a factory reset or take out the SIM and reinsert it. If it is still not working re-flash the pf2 firmware.
My GSM operator www.orange.md and CDMA (Number prescribed in the phone itself.) www.idknet.com.
I've tried to do is reset to factory Adapting and twice pierced him. Hotspot Menu appears.
You can easily sew G935P firmware from G935U? Problems will not be? Do I get bricks, blocks?
I haven't tried my self yet, but there is a whole thread talking about the unlocked firmware and using it on a print phone. You should take a look.
ok
I have an edge that is unlocked by tmobile.. in the app, permanent unlock (tmobile unlock app), it says.. "unlock failed" but below says permanently unlocked, unlock approved.. my understanding is this is a normal message.
When i went to the ATT store to test a sim.. they use their live sim, put it in, try to make a phone call but simply said it didnt work, isnt unlocked, which i dont think is right.. issue is i didnt see what if any error message there was.
Is there some step that the att rep should have done to get this on the att network besides putting it in the phone?
Thanks in advance for any info
edit: appears a special sim is needed, at least according to an online rep.. i was told to have them look up the IMEI with the MyCSP tool in the store to determine which sim.
I have an unbranded unlocked s8 that I got off amazon. I tried flashing the firmware to att (following the "switch to any carrier firmware 100%" post) to get wifi calling. After flashing it I was able to get the wifi calling option but whenever I click on it I get an error saying "Oops! We can't turn on Wi-Fi Calling for your account. Think this message is a mistake? Ask the person who can make account changes to call us...". Now my question is can this be fixed by giving att a different imei number? Currently they have the number for my unlocked s8, so say if I give them the imei number from my friend's att s6(he is currently using) would this feature start working?
Side question: I downloaded Phone INFO and Original CSC code is blank and Firmware's CSC Code and Active CSC code are both ATT is that how it's supposed to be? Also in download mode CARRIER still says XAA do either of these things matter?

Ymmv but if u provide an imei number from an att phone that has wifi calling capability it should work.

Does it matter if I give them an imei number from a phone that is currently being used on their network already? And do imei numbers ever update automatically or once I tell them the new number it was stay that number even if my phone actually has a different one?

Reason why ymmv is because some people said they have put their spouses imei number and it has worked. Others have said it reverted back to their original imei number.
When the phone tries to register for wifi calling, the IMEI of the phone needs to match the one ATT has registered to your sim card. Chat with ATT support online and give them your new IMEI. After they make the change, wifi calling will work.
Last summer I successfully flashed an SM-G935P (Sprint) to Verizon. I put it on the shelf without ever trying to use in on Verizon's network. I decided to switch to it from my S6 the other day. Before I did anything else I ran all system updates (via a wireless connection). All went well until I put in my already activated Verizon sim card. I get no coverage at all. Noda. The firmware loaded is G935VVRS8CRK2. Everything in settings =>About Phone looks right. Can anyone shed some light on what I may have done wrong?
P.S. I did try a Sprint sim card and it did show a 3g connection during initial setup. Is something left over from Spring that I need to wipe?
Flashing G935V firmware just converts your firmware to VZW (bootloader, radio, system) and you need to unlock your phone with Sprint still, but if you updated to Update 28 for S7 you can't go back to Sprint's firmware because the Update 28 contains bootloader v9!
TL;DR: you just need to unlock your device via sprint.
Here's a link to sprints unlock thing: https://www.sprint.com/en/legal/unlocking-your-sprint-device.html
The only thing is this, when I insert my Verizon sim card I am not prompted for an unlock code. Also, Sprint automatically unlocks their devices after ~50 days of active service on an account with good standing. Am I wrong?
Simple yet aggravating
So, the main issue I found after unlocking the Sprint G935P is (and I'm sure this is the problem you're having) you have to manually put in the APN settings to connect to Verizon.
Just Google "Verizon 4G LTE APN settings 2020" and enter what it tells you
Hi Everyone,
I just bought a brand new s10+ from marketplace. I ran a full imei report and everything is clean & not blacklisted. It was a sprint phone however the provider I use is consumer cellular (uses ATT towers). When I put my sim card in it obviously said invalid sim and request it get unlocked. I wasnt concerned because I was going to convert it to unlocked anyways via odin like I did my note 9. I reflashed it via odin with the u1 firmware. However the same thing is happening it keeps saying invalid sim and the button for mobile operators is not showing. I have a tmobile sim card and if I put that in it works fine. Being though tmobile and sprint are the same thats why it works fine. I also have a ATT sim card, If i put that in I get the same invalid sim message. So it still appears to be locked somehow. Only sprint / t mobile sim works. I thought by reflashing to unlocked it would unlock the phone sim.
Just to be clear the phone is brand new and never was attached to any account.
Any ideas? I dont know what to do here.
Thanks!!
As I understand, phones that are locked to a network are not just software branded... also the phones hardware ID. So flashing a generic firmware is not enough. You need to get the phone unlocked from the phone's original operator
I found out what I had to do. I had to use a remote unlock service to remove the software lock on the phone. Its fine now. Thanks
