Thanks to raduque, we can just click this stub and check if it returns a valid data package.

how did you unlock your s8?
[Samsung Galaxy S8 Guides, News, & Discussion] aybarchu:
I got the BOGO promo from TMB, and asked for a permanent unlock. They told me they couldnt because I have to pay in full the phone. I insist on it and after a lot of msg, they manage to perm unlock if I pay for 2 EIP.

My excuse was that i need to travel outside for 2 months..

does flashing another fw unlock your phone or is unlock before?
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Verizon LTE phones are always sim unlocked. However, some phones may not have all their bands unlocked.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
as stated many times, flashing fw doesnt magically unlock the phone.. it needs to be unlocked by the usual methods
[Samsung Galaxy S8 Guides, News, & Discussion] olabank:

[Samsung Galaxy S8 Guides, News, & Discussion] thecrunked:

I have an att variant , I called att and they told me they couldn't unlock it because I bought it from Samsung directly, I called Samsung and in order to unlock It, I had to do a 3 way call with a representative from my carrier so that they can confirm it was me and not some fraud, and they told me to factory reset afterwards and that was it
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
so u bought an att device from Samsung? thats odd lol
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Samsung sells all variants on their own but it's weird that ATT couldn't unlock for you. I bought my first one from Best Buy and the IMEI wasn't even in ATT's database which is stupid since it's ATT branded and comes with their sim. Settled for the Verizon one since BB didn't sell Tmo phones and I didn't want to order and wait from Samsung. Lol

Looks like the CSC was probably extracted from the ATT firmware that was posted to sammobile and updato

Here's a post to where someone supposedly linked the T-Mobile CSC as well: https://xdaforums.com/showpost.php?p=72193181&postcount=113
[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
Just a word of warning. I have tried to flash the verizon CSC onto the u1 rom trying to get gear vr to work... they are very different (even the file content inside the EXT4 file is different, and I ended up with something that installed all the carrier bloat from every carrier.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
thats because there is no verizon specific csc.. theres only multi csc files lol.. unless u r referring to the userdata partition..
[Samsung Galaxy S8 Guides, News, & Discussion] Skyrocket2Paradise:
I extracted the CSC files from the ATT firmware on updato you can give it a shot. They do have MULTI_CERT at the end of the filename though so odds are they're just the multi csc files packaged with the ATT userdata.

CSC - https://www.androidfilehost.com/?fid=745425885120736022

[Samsung Galaxy S8 Guides, News, & Discussion] fibrizo:
I'm talking about the home Csc. I even tried the user partition as well. Heck I tried combinations with the non home csc. The multicsc files are dramatically different extracted from the g950u1 ROM and the 950u rom
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
the home csc to my understanding wont wipe the device whereas the regular csc will
[Samsung Galaxy S8 Guides, News, & Discussion] umairaslam25:
I am in a similar situation, outside US for two months and they wont temporary unlock it unless i use data connection but I don't have data roaming. So phones useless here right now as I wanna use a local sim. This EIP is quite confusing for me. What do you mean by "if i pay for 2 EIP"? Did you pay t-mobile anything other than the monthly payments?

I was told at the store that i can't payoff the phone and get it unlocked if i want to keep the BOGO deal alive.
[Samsung Galaxy S8 Guides, News, & Discussion] angelsanges:

Hello,

I am novice in adb sheel.

I install eng boot without worry. Under cmd.exe when I specify adb device, my S8 appears :

List of devices attached

988XXXXXXX455733 device

its ok ?

However when I indicate the line :

echo "USC" > /efs/imei/mps_code.dat

I have the following error message:

"The specified path was not found."

What do you want to do?

Thank you
[Samsung Galaxy S8 Guides, News, & Discussion] Rushstrike:
I am assuming you are in adb shell when you used this command. If not make sure you enter it by typing adb shell.

You can also use the ls command to list all files in the directory:

ls /efs/imei/

no one seems to be able to get write permission to this file despite trying various engboot except for the OP.

[Samsung Galaxy S8 Guides, News, & Discussion] Rushstrike:
You should just type adb shell then hit enter.

Then you can issue the commands directly instead of prepending all your commands with adb shell. Your commands aren't really doing anything . But regardless we don't have write permission to mps_code without root accsss
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
not sure why this thread is even here lol we cant even use it since we do not have root even with the eng boots currently available

yea because we dont have eng root which makes me believe the op provided the process but hasnt actually done it successfully since its currently not possible

Just switched back to TMo firmware by getting unmodded version of Odin, loaded AP bl non-home CSC and forgot the last one now (not userdata though). Upon rebooting into recovery, it crapped out at 32% and threw me into main recovery, I wiped cache and selected factory reset and reboot as normal. It booted just fine and now back on TMo with Digits via multi-line settings enabled. Hd calling plus wifi calling functional.
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
You have a Tmo device? I've been trying to get back to a full Vzw firmware on my Vzw device and having no luck. Which Odin did you use? And I think you mean the CP file for the last one.
[Samsung Galaxy S8 Guides, News, & Discussion] elliwigy:
lol should be similar instructions.. u just have to flash until u get it lol
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
Been trying. Lol Going to try an older VZW firmware to see if that'll work. I mean at the end, if we can always flash firmwares to get updates without losing data, I guess that's fine as well.
[Samsung Galaxy S8 Guides, News, & Discussion] brnagi:
Can you outline the steps you used?

Does the T-Mobile unlock app recognize the device
[Samsung Galaxy S8 Guides, News, & Discussion] maidguitar:
Do you get the option to turn off shutter sound in camera with the XAA/ATT/***?
[Samsung Galaxy S8 Guides, News, & Discussion] vboyz103:
To answer your question, the unlock app seems to recognize my device because I opened it and request for a permanent unlock but failed because my phone is not paid off.

Steps

1. Download the TMO (5/1) firmware from Sammobile or updato and extract of course

2. Download the unpatched Odin version 3.12.7 (I got it from a thread somewhere on XDA)

3. Open Odin and load the appropriate file in the slots. For CSC, use the CSC_OYN or something like that BUT NOT the HOME_CSC

4. Put your phone in Download mode (Bixby + Vol Down + Power)

5. Plug your phone in. It should say "Added!!"

6. Click Start and wait for PASS

7. I skip USERDATA load.

Once reboot, your phone will go into recovery to update. In my case it reaches 32% and error out, then threw me back into Recovery. I wiped cache and did a factory reset there anyway. Rebooted and it sat at the T-Mobile logo for a good few minutes and then came alive.
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:
No, but if you turn system volume all the way down then the sound stops
[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
You might be able to use apps like Tasker to automatically mute the phone when taking a photo and un-muting it when camera app is closed. That is pretty much my only major gripe w/ using the U1 firmware. Might actually just use another camera app that can disable shutter sounds. Or we'll just have to wait for root to remove the stupid sound file.
[Samsung Galaxy S8 Guides, News, & Discussion] Shuthefrontdoor:
Do you have the option "identify unsaved numbers"?
[Samsung Galaxy S8 Guides, News, & Discussion] inneyeseakay:

[Samsung Galaxy S8 Guides, News, & Discussion] aybarchu:
This is the answer i got from t-force on twitter:

"Hi Nick, I totally understand how important it is to get that device unlocked before you'll be using it in Argentina! I want to make sure we're going over all of the options to help make that happen for you. Once the device shows in our system, and it meets the payment requirements of at least 2 EIP payments, we can over ride the unlock and help because you'll be travelling internationally. Does this make sense? I want to make sure you know what to expect! "

" EIP is the equipment installment plan you used to purchase the device. In order for us to have it unlocked and not have to wait for 40 days, we do need for at least two payments to be made towards that device"

--- "So if I do 2 EIP payments rightnow, will I get the full unlock without waiting 40 days?

"That's exactly right :) We'll still need to wait for that device to show up in our system as one that you're using, but that should be there for you tomorrow and once those two EIP payments are made, we can get that phone unlocked for your trip. :) Let me know if you need anything else. I'm happy to help!"

"It'll be totally unlocked. :) For your two EIP payments, you'll want to pay two payments of $20.14, a total of $40.28, and that will be all the payment necessary to meet the two EIP payment requirements. Are you able to follow the steps in the link I shared to get those two payments made so you're ready for the unlock process tomorrow? I'm here for you!"

"Since you are needing to unlock the phone to use it overseas, this gives us the ability to make an exception when it comes to the 40 days rule. As long as you have made the 2 payments, then you will not need to wait the 40 days that is listed on the rules online. This will absolutely give us the ability to permanently unlock the phone for you. :)"

Does anyone that has flashed the U1 firmware have access to Samsung pay in Gear Manager? After re-setting up my gear s3, the option for samsung pay is missing in the app. It was there previously on a stock U firmware.

It looks like it might be due to the same reasons the Gear VR doesn't work on the U1 model. I was digging around in the debug logs and came across this:

[Samsung Galaxy S8 Guides, News, & Discussion] gqukyo:
If someone can confirm the unlocked bands for on Tmo devices then all you would have to do is sim unlock the phone but I'm pretty sure they locked out bands that their service doesn't support. You could also try the *#2263# to see if you can unlock all the LTE bands. Vzw devices disabled some dialer codes like that so some of us (at least me), wanted to unlock all the LTE bands for use on Tmo service.

Vzw and Tmo does use bands 2 and 4 so it'll most likely work, you probably won't have band 13 to use on Vzw though.
