SIM card CSC change is no longer working

I tried and SIM card CSC change is no longer working, i have an INDIAN SIM and once inserted in note 20 ultra, it detects the sim but no longer pushes for a mandatory restart.

Something has changed somewhere, and i have a feeling its got to do something with One UI 2.5 update

Since the release of the S20 series this method no longer works. That's why everyone had to use samkey.org or the free apk by the mysterious Dev but since the August security patch both no longer works.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
That's sad to know.

However, I am able to change the CSC on my N986B/DS Philippine version.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] beautyangel:
How you were able bro, (Even following the youtube link) I follow all the steps carefully (No go at all). Personally i try to change my Rooted Note20ultra CSC no way, it remain the same.

By the way I try mysterious Dev APK Not working anymore.

I have root on N968B , if anybody has an idea of what will work, I am willing to be guinea pig :)
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] tribalfs:
I just did the *#272... method. Still working on my N986B/DS even after the Aug security update . I even reverted it back to the original CSC code before I sold it yesterday. Sold it and I have now the N9860 512Gb Hongkong variant. Tested the *#272... code but it's not working on this unit.

Since you're rooted, Just edit the cscfeature.xml file with <CscFeature_VoiceCall_ConfigRecording>RecordingAllowed</CscFeature_VoiceCall_ConfigRecording> and reboot. Voila!

2 things that made the *#272*IMEI# work on my N20U5G Exynos (Aside from having an OXM fw, see attached files)

1. I copy-pasted the IMEI. If I just type in my IMEI, it will not work.

2. I used Samsung's stock Phone app. Having been using an Android One device, I am used to using Android's Phone app. Since it's my go-to phone app in my N20U5G, the code will not work on it.

From my understanding, this code only works on Exynos variants of N20U/5G. Since the DATA feature for my SIM2 was disabled on its original f/w, I changed my CSC code to XTC. Now I can set DATA on both SIM slots.

CONFIRMED CSC CARRIER CHANGED Follow the link Below :

https://xdaforums.com/showpost.php?p=83451937&postcount=3

Well, Just Follow OP Instructions.

My Phone Rooted, I Follow Dr.Ketan Instructions how to root in Exynos section.

Am on latest Stock Rom, All Bloatware Remove with Adb Shell command.

1. I do Not install TWRP.

I extract Patched AP (magisk) and copy Boot.img, then convert Boot to Patched Kernel.tar

And Follow OP Instructions for CSC

"You will also need to edit mps_code.dat inside /efs/imei to reflect the carrier you desire. This needs to be done from a rooted system or from TWRP. After doing this and rebooting, you will be booted into your carriers system."

"Keep in Mind" You Must Copy mps_code.dat from your system to your SDcard then modify it with your desire CSC carrier Code. (For me I use Fx editor) (I have FX file Explorer Plus Root v8.0.1.0). Replace your Modify File to your System.

Reboot....

I confirmed All working Great Guys. We Can Change our CSC Carrier. "THAT'S A MAJOR MAJOR MAJOR GO". Really thats Awesome. Mentalmuso My Bro That's Awesome share Buddy. You Really Rock on this One.

voilà Done.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
I think most would prefer a non-root option as some apps may no longer function correctly (i.e bank apps).
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] fjorger:
Yeah tribalfs,

Same here. No way of changing the CSC of my N9860 :(.

So for now call recording only with an extra app "BoldBeast" (with some quirks - like lower sound volume on the caller side "compared to our own level", and non-working on Bluetooth calls).

But it's better than nothing (My Note 9 still has call recording "using the Thy SIM Swap/reset trick", but I wanted a new experience "need to move" :rolleyes:).

Cheers,

Hello, I have a N9860 with TGY and I'd like to change it to BRI. My phone is rooted. I've been trying different methods but without success so far.... Can anyone help ?

please someone help

Hello everyone, I really need help. I got the note 20 ultra and since i'm moving to anther country for a while i've tried to change firmware region with odin (I really needed that samsung pay). I've downloaded the smart switch app to get samsung drivers then made a backup. Then i started process according to the instructions. it started ok but it got stuck at the super.img i've waited for almost 2 hours and stopped the process. Now my phone in Odin mod. top left corner says (svb fail) and super: SignInfo (build ID is NULL). Is my phone a brick now? I'm really going crazy here it's almost 3 am and no progress. Please could someone help me out?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ikeieva:
try force restarting your phone using the volume down and power and see if it takes you the the screen where is says there was an error during an update screen and reflash the firmware again. it should not have taken 2 hours on that part and i can only assume that the app froze on your. with an average computer it should really take more that 5 minutes to completed a firmware flash
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mtsingson:
Does changing CSC affect 5G coverage? Changed mine from Philippines GLB to INS thru *#272*... method. Worked for my phone. But I seem to have lost 5G in a spot I usually get it. But luckily changing CSC enabled call recording for me and unexpectedly also removed my carrier lock. I'll just revert it back to GLB if ever I have to claim warranty
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] GalaxySFUN:
Just installed the original software, it worked. Thanks

There is some solution without root?

With root banking apps don't work.

I tried *#272 way and no luck.

I have SM-N986B/DS (Exynos) with OXM Rom.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
If you still get the option to change the CSC, I would advise you to go back to GLB or XTC (while the firmware still allows it), if you want to use DATA on SIM2. I was able to change my CSC to XTC and got the option to use DATA on SIM2. I made a mistake of changing my CSC from XTC to DBT - should have never changed regions. Now the CSC code won't work anymore. Does VoLTE work or show on your status bar using on INS?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] mtsingson:
I had the option to toggle VoLTE on and off with INS CSC. But i switched to XTC like you adviced. Wasnt getting 5G signal when I switched to INS. For me at least, 5G seems more fun the call recording.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] marvin6six6:
was able to unlock carrier by changing CSC from GLB to XTC but after the software update, my other carrier sim didn't work. also made a mistake of changing CSC to DBT, now carrier is locked. hope there's a work around to unlock carrier without root.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
can you expound? What do you mean 'carrier is locked'? You can't use SIM2 for DATA after the latest update? But you still get 5G right? How about VoLTE and Wifi Calling?

---------- Post added at 11:29 AM ---------- Previous post was at 11:25 AM ----------

Does the *#272*IMEI# code still work after reverting to XTC?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] marvin6six6:
Sim1 is globe locked, have not tried using globe physical sim yet couldn’t find the sim itself-been using esim on my other phone.

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Thanks for confirming. Although the toggle options for VoLTE and Wifi calling are available in the DBT settings, the Status icons no longer show up. I have yet to go back to any 5G enabled locations to see if 5G still works. So far I only see 4G+.

Hey, how did you request Globe to activate your eSIM?

Yes SIM1 will remain Globe-locked. SIM2 should be open to any network. Since you mentioned you're now stuck in DBT I'm curious to know if indeed DATA in SIM2 stopped working with the latest N986BXXS1ATH9 update. I postponed updating. I'm hoping the latest update for XTC becomes available and flash it with that, see if it reverts back to XTC - catch 22 I know but still hoping...
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] marvin6six6:
Just went to any globe store and have your esim enabled phone they will issue a qr code for your line.

Have not tried 5g though as it doesn’t cover my area yet.

The thing is sim1 was unlocked in my case when i changed csc from glb to xtc not until i performed a software update.

Successful change of CSC Code SM-N986/DS Exynos

RIGHT GUYS!!!. THE NEWS YOU'VE ALL BEEN WAITING FOR

I have successfully flashed the july firmware and used the mysterious dev csc change theme to bring up the preconfig screen with all the csc codes. I can confirm that this works on SM-N986B/DS Exynos.

I am currently uploading the firmware and will post the link as soon as it is done. you guys can download it from samfrew website but free downloads take about 12 hours. you can purchase a 3 day pass for 3.99. just search for N986BXXU1ATGI on their website and download.

my link will be free to use on the mega.nz website and it will be done in an hour or so.

if You have some method how to accross this, I will be very pleasured.

- Power off your device completely. Press and hold the Power and Volume UP keys together until Recovery mode appears. Select Wipe cache partition. When the wipe cache partition is complete, Reboot system now. Wiping the cache partition does not delete your personal data.

[Android Q&A, Help & Troubleshooting] Bricky7C:
Hi there,

I'd really be grateful for any help anyone can give. Yesterday, my Honor 7C got stuck in a boot loop, restarting at the blue Honor screen continually until the battery runs out. It's impossible to boot it into recovery mode using any combination of key presses. It just keeps restarting.

Can someone please help? I don't really mind losing the phone, but ideally I would like to save some of the data on it, as it had been a while since I backed up.

I understand that the way to do this might be to flash the stock ROM, root the phone and then run a data recovery program like EaseUs. Is this correct?

Also, I have tried to flash the stock ROM but really have no idea how to do it. I got half way through using SP Flash Tool before I realised that the Honor 7C is not a Mediatek phone.

Also, I can't find the stock ROM (LND-L29) anywhere except on pretty dodgy looking websites. Is there a reliable source for stock ROMs anywhere?

Any help would be really gratefully received. Thanks!

Your Honor 7C has a Qualcomm chip-set hence you might use free-of-charge QPST ( read: Qualcomm Product Support Tool ) to re-flash device's Stock ROM.
[Android Q&A, Help & Troubleshooting] Bricky7C:
Turns out my bootloop was caused by a hardware problem after all - ripping open the side of the phone solved it.

However, for anyone who stumbles across this thread with a similar problem, jwoegerbauer's suggestion of QPST was very helpful, but the tool on the site would not install for me on Windows 10. I kept getting an "installation was interrupted error". However, I found a working version of the tool at:

androidmtk dot com fslash download-qpst-flash-tool

[I'm a new user so XDA won't allow me to post a URL]

[Android Head-Units] kingdew11:
Good day sir.

Could you guide me as to how to extract the logo.bin file please? I couldn't really find it.

Thanks!
[Android Head-Units] threadreaper:
I'm planning to do a full tutorial on this too, but the short version is as follows:

Get SP Flashtool, and find a scatter file that will work for your device. That can be difficult sometimes, as there is a quite a bit of variance between units. Fortunately, to make your initial backup the only info you need in your scatter file is for the preloader, and as far as I know that is always the same. So if you don't already have a scatter file copy this:

#########################################__WwR_MTK_2.50__###################################################
#
# General Setting
#
#########################################__WwR_MTK_2.50__###################################################
- general: MTK_PLATFORM_CFG
info:
- config_version: V1.1.2
platform: MT3367
project: 8227l_demo
storage: EMMC
boot_channel: MSDC_0
block_size: 0x20000
############################################################################################################
#
# Layout Setting
#
############################################################################################################
- partition_index: SYS0
partition_name: preloader
file_name: preloader_8227l_demo.bin
is_download: true
type: SV5_BL_BIN
linear_start_addr: 0x0
physical_start_addr: 0x0
partition_size: 0x40000
region: EMMC_BOOT_1
storage: HW_STORAGE_EMMC
boundary_check: true
is_reserved: false
operation_type: BOOTLOADERS
is_upgradable: true
empty_boot_needed: false
reserve: 0x00

And save it as scatter.txt

Select this file as your scatter file in SP Flashtool, and click on the memory test tab. Uncheck all the options under memory test except for RAM test. Remove external power from the unit entirely, click start on the memory test, and then connect the 4 pin usb to your PC. It should sync up and do the memory test. Once the memory test is complete you will have the sizes of BOOT_1, BOOT_2 and EMMC_USER. Use these values with the readback option to make your backup. Use 0x0 as the start address each time, and the size value you got from the memory test. Back up BOOT_1, BOOT_2 and EMMC_USER and save them somewhere. This is the most basic backup that you can always use to go back to stock. Using tools like MTK Droid Tools and WWR MTK it is possible to split EMMC_USER backup into all of your separate partition backups.

Good luck, and keep an eye out for a more detailed walkthrough coming up soon!

I posted instructions on backing up a unit two posts above your reply ^^. To root, find a compatible twrp image and flash it, then install magisk from twrp. I will be doing more detailed tutorials on these steps in the near future, but as I mentioned there is a crash course on SP-flashtool backup in this very thread, and the root process is pretty much the same for these units as it is for many others, assuming you find a working twrp image for your particular device, so you shouldn't have too much trouble finding a walkthrough if you need one.
