Changing CSC on S20+ 5G - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

hello, a friend of mine recently bought S20+ 5G from UAE and he noticed that he doesn't have call recorder so we tried flashing a different country firmware but the CSC won't change and "Service provider software version" won't change no matter what we flash, so my question is there any way to get call recorder and change CSC?
thank you

Try this - Go to "Settings" then "About phone". Write down your IMEI Number. Open dialer and enter *#272*IMEInumber# (In the thread replace IMEInumber with your actual IMEI Number). Press dial, you should see a screen with the list of available CSC codes for your device. Select the CSC that you want and tap the Install option.

yes tried every code there is but nothing works
heard Samkey could solve this, is there a tutorial for a more recent phones? oneui phones? because most of the reviews and tutorials are mostly old ones

greetings
i have this problem too
I have a sm-g986B/DTM (s20+ 5G) and need change from dtm to dbt
i found firmware G986BXXU8DUF9_G986BOXM8DUF9_DBT
Flashed him on my device
Odin said
All threads completed. (succeed 1 / failed 0)
but in the end when i turn on device i see DTM((

A csc dialogue code, may work or not.

sadly tried all the codes and nothing worked, all i have left is SamKEY, saw some reviews and it might be the only chance to change CSC, anyone has some experience that could guide me to which CSC i should change it to have call recorder?
thanks in advance

SAMKey is a paid service but prople have paid for it and have successfully changed their csc so. You can try it. I haven't personally used it so good luck with that

Did you manage to change the CSC of your S20+? I also need to change mine.
I have a SM-G986U1 / Snapdragon model, which doesn't have e-sim, app lock, call recorder. I use mine in Brazil and it was purchased in the USA. I was wondering if you found out which CSC to use or if you did something else.

First you need downgrade to android 10, it's very important. After downgrade setup your device and install google phone dialer (please dont use after 2021/03 google phone dialer apk).after iinstalling google dialer type this code *#*#27262826#*#* .
Now you can change your csc
Please Remember That - Change csc via this method, your all data will be erase, please backup all important data before do that.
Thanx

If you downgrade to A10 on Samsung you gonna brick your phone because of bootloader rev differences.

Any idea how to downgrade? Or it's not possible anymore?
And does SAMKey method work on android 11 and latest bootloader?

It works on android 11.

It is supported by your phone. The binary version isnt an issue and you do not need to downgrade.
SamKEY has been updated to support A11 some time ago.
You can use the software.

Yes, I'm working on getting it to work, but I cant get the app to open the specified file. I get permission error. Any advice on how to read system files would help a lot! I have got SuperUser to grant root access.
Thank You for this. I must not anymore cheking new firmware with Kies or with login on Samfirmware. I was checking some product code with your apk , and i got really interesting result, but right.
Once more thanks

It shouldnt be any difference, voodoo only modifies the kernel, and the app should start anyway, like any other application, its made to work on Android 1.6. Did it work prior the auto-discover of ProductCode and HIDSWVER?

I just downloaded and flashed via Odin a couple of hours ago. First impressions doesn't differ much from Android 9 with OneUI 1.1. Themes are not supported and the menus look quite similar, it seems there is QuickShare and MusicShare

Themes were a thing also on oreo and pie, so I guess Samsung never planned to port them on tablets, not surprising at all.
I hope at least that the update brings some multitasking functions from the tab s6, like the side panel
Here's an overview: https://www.gizchina.com/2020/06/23...oid-10-with-one-ui-2-0-for-the-galaxy-tab-s4/
Excuse me, could I flash this?
Apparently for t830 they just released an update (security patch, 140mb) still on android 9 instead of the android 10 and one ui 2 upgrade ?

No, you can't downgrade right now (after update to android 10 I mean)..Some few samsung devices with "beta 10" program in the past, can and do it through "smart switch" & rollback package,but no the Samsung Tab S4 unfortunately ....

EMUI 11 [Global] Huawei P30 (ELE)

Huawei has finally begun the rollout of EMUI 11 for the Huawei P30 (ELE) and P30 Pro (VOG) today. The version is 11.0.0.138 and the package size is about 1.81 GB.
How to check for the update:
1. go to Settings then System & updates, then open Software update, select Check for updates
2. open the Support app, go to the Service tab on the bottom bar, tap on the update, then select Check for updates and then download and install
3. connect to a PC with a USB cable and check for updates in HiSuite
Feel free to share your experience with EMUI 11, please also share the exact type of your device (e.g. ELE-L29 C431E27R2P5) and how did you manage to update to EMUI 11, also mention from which build did you update.
In case the download method or updating with HiSuite proxy will be available, also share a how-to and I kindly ask you to perform a SafetyNet test.
I used VPN and chose China, then set the region of my phone to Nepal yesterday. The Support app found 10.1.0.201 with this trick. Then today, about an hour ago I checked the Support app again and it finally offered me to update to EMUI 11. Hooray!

They didn't, that was my point. It's only newer devices that are without Google services.
I just got my P30 (ELE-L29 UK Unlocked) updated to EMUI11, updated to the January security update, then enabled my VPN with china selected then checked for updated in the support app.
Also a sidenote, this is EMUI11 but it's still android 10, and good gesture navigation is still not working with Nova launcher
Edit: Now fails safetynet, so no google pay for now....

How come that your phone failed the safetynet test if you updated via OTA? I'm on 11.0.0.138(C431E8R2P3) and it passes the test and Google Pay works fine.
I believe that gesture navigation will not work perfectly if you use a third-party launcher. I use Evie launcher and I also had to install MyGesture app from Play Store. I like it better than the stock gestures, more customizable.

I have no idea, I did a backup with hisuite, factory reset with recovery mode and now it passess, so it might have been a bug or one-off or something ¯\_(ツ)_/¯
got update today, UK Vodafone, ele-l09 /c431e8r3p3/
Yesterday my phone received the EMUI 11 update (build 11.0.0.138), no need to do any trick. Model ELE-L29, unlocked, Spain.
Since the upgrade, VoLTE was enabled (it was off before the update) and the option to disable VoLTE is no longer available on the settings menu.
Anyone with the same issue? Any way to disable VoLTE using call codes or something else?
Stll nothing here. Getting frustrated because the website for my phone company shows the update as being released.

Question 5G not working in my OP 9 pro

helle there
i hav problem in my OP 9 pro

Have you got a subscription with 5g at your carrier? Does it need to be enabled as an option? Has your carrier deployed and activated 5g in your zone (you may find a map for that somewhere)?

Sorry, that was just to be sure.
I can only say that my phone, bought from oneplus for France, running Oxygen Os 11.2.3.3.LE15BA, with the French provider Free Mobile is getting 5G.
I can't provide more help, I hope others will.
Check Settings>Wi-Fi & Network>Sim & Network Settings
See if "Smart 5G" is enabled, try toggling it off or on to see if the phone connects to the 5g masts
Also check the APN settings for your provider's 5g and see if you can add it manually, if you can and it works then raise a support ticket with OnePlus so they can add it to their list
If you need to add a manual APN :
Go to Settings>Wi-Fi & Network>Sim & Network Settings>Access point names
Tap the + sign at the top and enter the details as provided by your supplier.
Your model is listed as AA which is Global but I would still check if the 5g bands in your country are supported
Hi,
Same issue with me. I reported it to Oneplus and they were helpful. They told me to wait for the next update.

It happened with OnePlus 8T and the solution was to download a carrier policy file and replace it with the current one on your phone. Requires a PC.
I don't know if it works on OP9, but heres how it is on oneplus 8T.
I have made list of networks where OnePlus 9 and 9 Pro have 5G enabled: https://gist.github.com/olkitu/888072a29d32f8197d2e86b428225e5c
If not listed, you can wait or enable it using this instruction: https://mt-tech.fi/en/modify-oneplus-7-pro-5g-8-and-8-pro-nr-lte-a-band-combos/

I have read your github page but I found China Mobile 5G NSA and SA bands are N41 not N40 actually.
Could you tell me the carrier policy filename and path in the firmware. I want to confirm some bands is supported or not in DA/BA/AA Oxygen OS.
Thank you.

Oh yes there is mistake - fixed now. Qualcomm report 40 but of course forgot add +1 = so then it's n41. That is just format.
Carrier Policies are in mbn (modem) files in policyman directory.

Thank you for your help. I have found what I need. But unfortunately Oxygen doesn't support SA N28 band. It will be a problem in China.

By the way if you have OnePlus 9 Pro Chinese version would you like to contribute your device log when you are connected to 5G-network?
Here have already listed 4G combinations but would be also good list supported 5G combinations: https://cacombos.com/device/LE2120 . You can contribute https://cacombos.com/contribute if you like.

hi did you get 5G to work?
if you did kindly share the "carrier_polixy.xml" file with me i am trying to modify but not showing 5g in setting
or at least send me step by step how you did make 5g work exactly
thanks
Hey,
decided to risk it and used the Carrier_Policy.xml from my oneplus 8 pro, which was provided from someone else in another thread.
For the sake of not breaking your phone on my behalf, please use google to find one.
regards.

Which country are you from? And what network do you use?

Question Is there an in-built call recording? (CSC locked is OK)

I want to buy an S21 FE 8/256 phone, but I need call recording. I know my Note 9, Note 10+ had this call recording feature in "Phone", if I changed my CSC to India for example. Worked great, no complaints, its just what I need.
But can I do it on this phone as well? Like does Samsung still support call recording?
Thanks!

Oh yeahh this is the way I've done it. But does this work on the S21 FE right at this moment? With the latest rom/firmware too?

I am not sure where Samsung is on recording at this time. For non rooted devices there is a call record button on the stock phone app. If the button was missing a up date from the play store would restore and show the button. I don't know if Samsung has blocked this or not. However, this stock method of call recording will let the other party of the call know they are being recorded. Here is Google support page on this:
https://support.google.com/phoneapp/answer/9803950?hl=en
Skvalex is the only app I have used for call recording, going on 8 years now. Can work on some devices out of the box and rooted for most devices. Keep in mind firmware may have to be changed. You can check it out here:

Few threads below, three about this topic. Sure it works, samkey and SEK csc. Snapdragon version meant for EU is without obvious countries like INS, SRL etx. Exynos version is APAC so plenty of choices of csc. Well version of FW, where samkey works ? Try out latest one, but IMO downgrade is still on option via odin.
So, despite what ING.KING says, it is not possible to put CSC SEK on snapdragon models. He tried with another model (maybe exynos) .. tried in person with both first and last firmware, IMPOSSIBLE CSC SEK.

Try to downgrade FW with odin. I applied CSC change with Samkey at the end of February with: G990BXXS1BVB3 original CSC TMS and Snapdragon .
Latest FW G990BXXU1CVC3 consist of OneUI 4.x upgrade, probably it is not supported by samkey yet.
Samkey replied that at the moment sek csc is not supprotato either with this or with any other previous firmware. After all, I had already done tests on the advice of ING. King but it was not possible to change it. On s22 changed in a moment... But not on s21fe. Can you send me a screenshot of your csc? So I turn it to samkey

Thank you, I immediately turn (if I have your consent) to SAMKEY because they say that it is not possible to switch from EUX to SEK.
As I mentioned above, in my case CSC was changed from TMS Tmobile Slovakia to SEK.
Before SEK, I tried also SER(Russia) and CAU (Georgia) but none of them has CallRecording.

Oh man, this sucks big time.
So basically EU + Snapdragon -> don't buy phone.
Man, I wish I could find a solid phone on the market that won't set me back 9000$ and would work alright. I've looked at OnePlus, but their software has been a trainwreck since the new big update (Android 12 / ColorOS Frankenstein thing), and you get a mediocre phone. Sure, it works. But is it 1000$+ good? Hell no.
Xiaomi loves using their virtual proximity sensor that just WON'T EVER work OK.
Google doesn't really sell in EU (only select countries), and the phone I'd like to have (5a 5G) is Japan/US only.
ASUS comes with call recording, but they are still selling their older Zenfone phone for 1000$. Crazy.
Ehh, why is it so hard to buy a phone in 2022.
I just want root, or native call recording.
I manged to change CSC using SamKey to SEK it did unlock Call recording option but its still locked. Any ideas?
Strange, never seen that before. Once csc with available call recording, no such lock... Unfortunately my s21fe is being claimed, wonder if I will face same issue after it returns. if the mainboard is replaced question is with what firmware they return it. Maybe after some update csc change stopped to work way it worked before. I was lucky changing csc with second firmware version before 4.1

Have you enabled it in caller menu three dots right upper corner and call recording automatic ?
yes i have enabled like you see on attached SS
well my phone returned from operator, fixed with changed mainboard and battery cover. CSC is Back to TMS/EUX. I will try samkey afternoon and later post the result. Expecting the worst but hoping for the best
no luck, samkey cannot read IMEI, N/A. Due to this, procedure of CSC change won´t start. Simply wait for next generation of samkey with support or accept no call recorder
just for the record latest May 2022 firmware
update, CSC change working fine even on latest FW. Call recording working. Just needed to install usb drivers from samkey.

Hello, I want to buy a S21 FE EUX Snapdragon but I need Call Recording. Can you explain the procedure you followed to achieve it? How many credits are needed to change the CSC? Which CSC have you chosen?
Thank you very much.
