[Q] How to unlock Galaxy S4 SCH-R70 US Cellular

How to unlock the Samsung Galaxy S4 SCH-R970
I bough this phone online thinking that i will unlock and keep using on different carriers even outside the US (GSM)
I have done a lot of researches online and i cannot find any solution. The imei is only 14 Digits and almost all online unlocking services doesn't have this model.
The usually codes like *#0011#, *#27663368378# they doesn't work at all.
I have tried to go to unlock stores or guys who knows to unlock phones and he said that this phone cannot be unlocked.
phone has a sim card slot so it should be CDMA&GSM
When i insert a different sim card provider it says Invalid Sim Card so i cannot enter any unlock code
ANY IDEA or i will lose 500$ for bad phone

Uscc is not a gsm phone the sim card slot is used for thw 4g service the phone itself is cdma

Samsung gs4 sch-970c (cricket)
Samsung has told me this phone will work either gsm or cdma. Cdma is the way cricket first sold it. It cannot be unlocked. It is cdma. It has to be flashed to a new carrier after it is rooted. The sim is locked via software. Not many codes and all the unlock codes you read about are for gsm. The ##366633# code you mention gets you to a disable or enable developer mode.

i also have the same issue. Not resolved yet. but I did find out this that might help: if i pull up a website that checks the MEID number it gives me the whole description of my phone plus an extra digit on the IMEI number. I wonder if this is why third party unlock sites cant help me

Who has unlocked cricket sch-r970c?
Same problem. Cricket said they cannot find the unlock code if the phone was never activated. So this was never activated.
I have rooted it to OptimizedCM-12-1-20151130. Is it now unlocked?
OR, who has successfully flashed a custom ROM to unlock the software lock on it?

The struggle continues...
I just repaired my USC s4 LCD digitizer and now that I am no longer a USC customer wanted to unlock it so I did some checking, if you go to US cellular they will unlock the phone for you, I got my unlock code, but they said they couldn't complete the process if the phone was rooted (Which mine is), you would have to reinstall the USC original firmware, or the latest firmware, to get it to unlock, then root it. I am doing some research now to find out if there is indeed an alternative to unlock a rooted phone...

I just left US CELLULAR where I was told nothing below the s5 could be unlocked,and the only suggestion from any one employed there was to call customer service.

you try RegionLockapp ???
I unlocked my t mobile s4 with it, i had to flash to a earlier firmware, then root, then use RegionLockapp, then re-flash whatever rom you want.

Flashing international Firmware

Hello everyone,
yesterday, a family member gifted me an s7 from the USA (SM-G930P). He bought the phone off SPRINT as a SPRINT unlocked version, and, of course, because I live in Europe and want to use the phone with a European SIM card I have the "hands free activation" mark that is sitting on the top left edge of the display. I also noticed some changes, for example the "mobile data" toggle is nowhere to be found and also I don't have the options to choose the network mode (2G/3G/4G). I love the phone and I also would like to keep using it, I only need some answers from you guys.
My first question is, if the phone will actually let me use 4G network with my European SIM card, or will I be limited to 3G?
My second question is, If I can flash an international firmware for another carrier and another country on the phone, and if so, will I have the advantages of that firmware, like the Mobile Data Toggle??
Thank you very much for your answers.

If you install the 'Network' app you might be able to change the network type.
In general you should be able to use an unlocked P variant with a foreign SIM but you may have to activate with a Sprint SIM first.
You can't flash the international version since it's Exynos and the P version is Qualcomm CPU.
I am not sure if this model has Samsung region lock which is another thing to consider.
If I was you I would try to flash the U firmware (US unlocked) as it has the most support for international 4G bands among the Qualcomm US models. It also doesn't have all of the Sprint bloatware on it.

Thank you for your reply. I am currently using the European Sim from my carrier and I have no problems with it. I managed to get rid of the Bloatware by using Package Disabler Pro, but it still sits there somewhere on my phone. So far, the phone is working very well and other than the bloat sitting on my memory and the lack of LTE, I have no complaints.
Can you tell me if someone has tried to flash the U firmware on a P model with success?

Could you tell me how you did it, or link me a guide??

I had bought an unlocked Sprint galaxy S7 (930P) off ebay which died on me. Got it repaired from the service center and they sent me a locked device instead. The phone is currently on Software Version - G930PVPS4BQC1 and the hardware revision is Rev 0.6. I'll be using the phone in India and have a few questions.
1. I need to get this SIM unlocked from a service online. Does anyone know of a reliable place to do so?
2. If I flash the U Rom on it after unlocking it, will I lose the unlock? (I don't mind downgrading from Nougat to Marshmallow)
3. Should I unlock first then flash the ROM or flash the ROM first and then try to get it unlocked?
4. Will flashing the ROM directly unlock the phone itself?
Please advise.

...
you could try gsm zambia to unlock your phone it works i tried it myself a few days ago, also after my phone got unlocked i flash the U firmware/rom and the unlocked remained. so you should unlock your device first then flash the U firmware :good:
PS. if you one nougat better to downgrade if you can do marshmallow so when you wont have any issues flashing to U firmware. :cool

S10 5G G977U and G977T Combination (Factory Binary) Files Here

Early access for those of you who know what this is, and want to see what you can find inside. I compress extra small for storage and bandwidth savings, so you'll need 7zip or WinRAR etc to extract - the default Windows unzipper can't handle it.
Retail firmware should be coming soon, and I'll put up another thread similar to my existing ones, once I have access to it.
https://www.androidfilehost.com/?w=files&flid=292080

Hmmm.... A G977T Combination file has now been released. This is very interesting, because Samsung stopped using specific carrier designation letters in their model numbers after the Note 7, for all flagship devices. Not sure what the differences may be between U and T, but that's exactly why I'm providing the links

for G977T we must waite for the full firmware ( there is no CSC in a combination firmware )
about Verizon firmware i can say firmware is SM-G977UVRU1ASE8 G977UVZW1ASE8 multi CSC
regards

Yes, I know - I have already posted the full firmware in a separate thread.
So far, there appears to be G977B, G977T, and G977U models. So we'll have to wait and see what the differences are, and how the firmware will differ

Hi;
Do you guys think there'll be an unlocked variant on the State's side?
Would it be necessary? Or just SIM unlock the Verizon variant?
Thank you.

I have not seen any references or mention of a 5G U1 variant yet. And I'm not sure if the Verizon model is going to already be SIM unlocked, like most of their phones are

the VZW model is sim locked!!!

after set up I switched Sims, it recognised the new sim but then said this phone cannot be used with this sim!

That doesn't necessarily mean that it's SIM locked. Pretty much all Verizon phones show a notification that says "This is not a Verizon SIM" - even if they're unlocked - if you insert a different carrier's SIM. If you can post a picture or screenshot of what you're seeing, that might help us clarify things

this is the pop up that occurs

Posting a picture or screenshot would be a lot more helpful.
Is there a place to type in a code, or does it say "tap here to learn how you can use your device on another carrier's network" or anything else?

anyone know where I can get the firmware for the sm-977n ?

Will these work with the SM-977N ?

Buy the $30 prepaid plan and leave the Verizon sim in for 24 hours after its activated and then pop in another sim. Should work.

The Verizon G977U comes unlocked. I am currently using T-Mobile. I don't mind bc I upgraded from note 8. but I just don't like the Verizon boot and all apps ect.., also the "non Verizon Simcard "message.
in my note 8 I put any simcard and it will reset to that simcard carrier with original carrier boot and apps. . I will like to have the same effects in this device.
if anyone is interested in testing with this device it is available.
I've seen G977N in YouTube and it doesn't have any carrier (maybe that's the unlocked version)

Will this support S10 5G firmware?

The SM-G977T model will be for T-Mobile. Saw the phone being tested myself. Here's a link showing the test firmware on the TMB csc: http://fota-cloud-dn.ospserver.net/firmware/TMB/SM-G977T/version.test.xml

You have to wait for 24 hours now with Verizon, then the phone will unlock automatically.

What? Im assuming over asked question?
I mainly ask because at one point there was a way around it with the one plus 6t. So i wasn't sure if there was a way currently with the 7T Pro.

Far as I know there has not been a guild without it

Short answer: no. Unlock code is needed and MSM Tool can only flash T-Mobile software now.

After the device is paid off AND been on the network for 40 days THEN you can get an unlock code
EVEN if the device isn't from the original owner AND YES: it HAS to be registered on a POST PAID account for 40 days for this to work, prepaid has different LONGER rules and I forgot them.

So how do you get an unlock code?
And to clarify a SIM unlock code not token from oneplus. I know how to do the latter.

Both incorrect. Apparently no one can read the title of threads in our subforums before either asking questions or answering them incorrectly.
@15jpenni
A hacked MSM version was made that allows you to unlock the bootloader and therefore root your phone with Magisk. It won't, however, carrier unlock the phone from T-Mobile vs. if you properly unlock the phone through T-Mobile as the official method that @RypeDub mentioned. Try reading the thread and see how u can do it unofficially:
T-Mobile 7T Pro 5G McLaren bootloader unlock without SIM unlock/OnePlus unlock token!
Here is a patched MSM download tool for TMobile OP7T Pro 5G McLaren. It will bypass the need to sim unlock before unlocking the bootloader, and will also bypass the need of an unlock token file from OnePlus (hence skip the wait period of 1 week...

OP7T PRO McLaren Edition 5G T-Mobile - get rid of T-Mobile stuff/flash international/other solution

Guys,
I have read the whole forum and my understanding is:
My phone is Model HD1925, purchased in B&H.
- there was no option to flash international / stock non t-mobile firmware in 2021 at least. Is it possible to do now?
- if flash international/non t-mobile firmware/rom is not possible, is it a way or need top get rid off from T-Mobile soft ?
- is it another custom ROM which can be installed?
There are several sites, I have found which provide an instructions to flash international firmware, but this is really opposite to xda forum and makes me suspicious.
The phone will be given to a kid, so I prefer to clean it up from unneeded SW and also keep it up to date due to security reasons.
I'm not living in USA and not care about 5G.
The phone is SIM unlocked and bootloader unlocked using OnePlus .bin file.
Current version is 11, April 1, 2022 Update.
Really appreciate your help.

Hey, there. I'm sorry to tell you that you can't do that, because the hardware of 1+7tpro International Edition is very different from that of McLaren special edition. Before your release, I have tried to use the 9008 after-sales firmware of Chinese Version (hd1910) to brush into this phone, but unfortunately, this phone can't work, and even entered Qualcomm's crash mode. My suggestion is to use ADB to freeze all programs related to T-Mobile, so, You can enjoy 5g and later OTA updates.
