Get rid of Sprint

Hi guys, need some help.
If I switch carrier then phone automatically get bad Sprint ESN, right? If so, thats ok, because I dont want to use Sprint.
I've got Sprint L710 but I never used CDMA before, so little bit confused with how to get rid of that Sprint and make it work with Boost even w/o 4g.. perhaps 2g or 3g if possible. Or Virgin, doesn't really matter, the most important is prepaid plan w/o contract.
I'll make a root and even if then I install custom ROM then still will be using Sprint? Or after flashing custom ROM I can go to Boost and ask them to flash their codes?
Nobody else will help me, I hope for your understanding.

As far as I know. You won't get bad esn as long as you don't have any pending balances pending.
And if you pay the early termination fee.
But I'm not sure. As far as the s3 on another net work then it would have to be flashed with whatever company your gonna use it with.
But your probably better off just selling it on craugslist or eBay and buying an unlocked international version.

When I switched from ATT contract to TMobile prepaid I just unlocked phone, pulled out ATT sim card and go forward with TMobile. I didnt make any notifications to ATT, TMobile just transferred my number in few secs.
I mean how could I make same on CDMA? Could by example Cricket take my phone to their network? Is it possible to delete all related to Sprint from my phone, make it clean as from factory? And then come to Cricket or another CDMA carrier? In that case if I terminate Sprint contract without any notification I think ESN would be bad.

Well if your gonna flash the phone to another carrier like cricket. Then bad esn or clean esn don't matter. Just go into a cricket store and tell them you need to flash your phone and they'll put other on their network.

And am I be able to get at least their Cricket's 3G?
Or for that I need to go through special procedure with donors?

What? lol
they should have a cricket store where they flash phones. Idk how the procedure is done, or how it affects the phones. But there might be something screwy with MMS, but you can always ask before you do it. and there might be a fix for that sort of stuff here at XDA

Cricket said that they flash only their phones and I cant keep my existing.
BTW finally we've switched it to Verizon prepaid

weird, down here where I'm at, they flash any phone really.
well if your S3 is just a brick there you can always sell it.
If the price is low enough i can buy it from you, or also ebay

They said that in New York area they flash only Cricket phones.
But even good, cause because of I that I got Verizon.

Friend's Galaxy S3 was locked by AT&T

So my friend has a dilemma here. He bought a Galaxy S3 off craigslist a while back. Now one month later his phone was locked by AT&T because it was reported stolen by the person he bought it from. Is there anything he can possibly do? He has already called AT&T and they refuse to unlock the phone, he can't use it whatsoever on his AT&T service.

Unless I'm wrong, he's pretty much screwed.

Whenever a purchase on craigslist is made you must always insist on the person giving a receipt signed by both of you. Your friend seems to be Sol.

Is there more to the story you're not telling? What is there incentive for doing this?

I wasn't aware ATT blocked IMEI like VZW/Sprint block ESNs. That's unfortunate about your friend's phone.

Sell it to someone internationally if you can unlock it.

A family member of mine in the caribbean, Trinidad to be specific purchased a factory unlocked TMO version Samsung Galaxy S3 from someone and now they seem to be having trouble with making and receiving calls on their network (Bmobile is the network there). I told my cousin that he may have purchased a stolen phone and the IMEI may have been blacklisted but I didnt think that was possible internationally? Could there be another reason like the network is not compatible; Bmobile is in the process of setting up HSPA+. The phone is also rooted. Could that be a problem also? Thanks in advance for any help you can give me. Also he has been receiving a software update from TMO, the 94mb one. Could updating the software make it work?

Carrier Unlock??

I had my phone unlocked through tmobile. I ended up leaving tmobile and they aren't working with me to pay off the phone. I currently have it working on att but I'm worried that in a couple months it's going to lose service bc they blacklisted it. I'm on att prepaid. Does anyone have a personal experiance with a bad imei tmobile phone working on att prepaid or even another prepaid service like straight talk or even verizon?

I had an issue with Verizon once with a note 3. It was a Verizon phone and I flashed a Beanstown rom and this tool called Casual by Adam Outler and it removed the lock bootloader and installed a patch to stop the update from we very coming through its been a couple of years ago but search like that. But in most cases if they unlocked it your fine. I'm still with them and have been for 6 years.

Moto G6 Play xt1922-7 issues

Ok long story short I got the phone off fb marketplace supposed to be unlocked but of course mt att prepay sim says invalid... and does not prompt for unlock code
looking into the phone it doesn't have a sprint rom as the rom ends in JETER_NA_CUST and not sprint... plus there is no sprint bloatware or anything.
but going to UICC Unlock it does say it is locked to sprint....
and it does say sofware variant sprint and software channel sprint
anything I can do to get my att sim to work

Nope. You bought a Sprint/Boost Mobile device which uses CDMA like Verizon. AT&T, as well as T-Mobile, use GSM.

I have mine on boost and the basband still says jeter_na_cust just like yours. It's a sprint/boost rom. You definitely bought the boost/sprint variant. It won't have sprint bloatware but it should have boost Mobile bloatware. If not the person you bought it from tried to flash the retail version from Best buy onto a sprint/boost variant. I hate to say it man but the person you bought that from definitely just scammed you. Because if they did take the time to try to flash the retail firmware then they knew it wouldn't work on att to begin with. Best you can do is either flash the proper firmware on it and activate it on sprint prepay or boost ( which tbh there both better than att despite what sprint has said about there own network lately) or you got a WiFi device. actually. Do you know the device model like mine for example is the xt1922-7 which is for sprint/boost.

It is the xt1922-7. There is no bloatware from boost either

Well either way the best you can do is get it activated on Sprint and or boost Mobile. It won't work on att.

My G6 Play is disconnecting Bluetooth all the time.

Question T-Mobile Network Issue

Hello
Hopefully someone here can point me in the right direction for help or assist.
I purchased a unlocked Galaxy Z Fold3 off of Swappa.com. Ive purchased many of phone off this site and had no issues including this Fold3. When I got the phone i placed my T-Mobile sim in the phone and all was fine since the phone was unlocked. When T-Mobile pushed the Android 12 update out we all know it caused issues with the phones network. Since i did not purchase the phone from T-Mobile i sent my phone to Samsung so they could fix the issue. Since they knew of the issue with T-Mobile they replaced the motherboard of the phone. Well that sim locked the phone to the original carrier which i found out was Spectrum Mobile. Spectrum states they cannot unlock the phone because they cannot see the IMEI on their network. T-Mobile sees the IMEI on their network from when i used the phone before the update, but they stated that since the original carrier is Spectrum, they have to unlock the phone. Samsung states that one or the other will have to unlock the device because they do not have carrier unlock codes even though they replaced the motherboard which cause the phone to lock again. After weeks of the back and forth i paid a site to give me a unlock code for the phone via Spectrum Mobile. the code they sent did not work and they refunded me my money. But now im stuck with a brick unless i get a Spectrum Mobile account. The phone works fine on their network but i refuse to get their internet service so i can get a mobile account just to use the phone.
Anyone have any advice as to how i can get the phone unlocked again? I reached out to the person i purchased the device from and they didnt have the unlock code. Also the IMEI is clean because Samsung, Spectrum, and T-Mobile checked it.

Right now, you can either pay for an unlocking service or, and this is the REALLY hard part, wait until Spectrum's IMEI Database is updated with the new IMEI for your device. This will come from Samsung when they Sync, but no telling how often that is.
The bad thing is, it can take weeks or a month or more. No one knows.
If you are in need RIGHT NOW, I would look for a good Unlock Service and pay them, but it can also take a while with how new these phones are.

I have an Unlocked Fold 3 also now using the T-Mobile network and keep experiencing network connectivity issues. In placed where I used to get good 5G signal now I only get LTE and sometimes my data connection drops to H or H+, sometimes just R for roaming.
So they believe the Android 12 update killed the Motherboard in our phones for T-Mobile? Also how long did it take to get your phone back from Samsung after the repair?

Samsung sent me a shipping label that was two day shiping to them. it took about a week or so to get back. Yes, something with the T-Mobile Android 12 update caused an issue where Samsung has been replacing the mother board of the phones. I found out when i was looking on T-Mobiles forums and a person stated that is what fixed theres. So i contacted Samsung and told them about the Andorid 12 update causing the issue and they had me send it in since they knew of the issue.

Thanks for the quick reply. I have had my Fold 3's screen fixed in the same day by going to a local UBreakiFix, any idea if they can also do the Motherboard swap out?

@Talderon ive tried two unlock companies so far and neither have been able to unlock the phone. The person i bought it from wants me to mail it back so they can unlock it with a pc. Not going to happen so i won't get it back LOL. I think im just going to get on a friends Spectrum Mobile account and wait 30 so they can unlock it. Think thats my only choice.

If I'm on Google Fi (Which is T-Mobile) is it better for me to get the T-Mobile version of the phone off of Swappa/eBay so I don't run into these issues?

Just buy the samsung unlocked version and then flash the t mobile rom to I have the u1 one version I never had any issues with using t mobile on my z fold 3 and you need the rom bc its helps with towers bc I was using verzion rom on t mobile and I didn't get all the service or 5g uc always buy us unlocked version never buy carrier ones bc it's just easier to flash the rom you need than buy the carrier one bc it's can be relocked at any time bc when I bought t mobile version s21 it's locked the phone so beware

See you shouldn't buy carrier phones don't do that bc you always have issues and it's hard to find unlocking service just resell the phone and just buy you unlocked us version off ebay and then flash t mobile rom and you be good and then you don't never have to worry about having a brick
