[OPPO Find X2 Pro Questions & Answers] klanbo78:
Afraid not, I sent the phone back to Oppo and they flashed it. TWRP wasn't available for the X2 pro and didn't work for Android 10/11 anyway, although I heard there has been some progress on that front. You should stand a chance on OnePlus though as not locked down and more tools out there.
[OPPO Find X2 Pro Questions & Answers] thirtythr33:
yeah bro thanks anyway, this is quite a clusterfck here, it blows my mind that my phone boots find on slot A yet I cannot update my rom because apparently I am missing those critical partitions, and when I try to flash them they tell me they are not found. lol wtf man
[OPPO Find X2 Pro Questions & Answers] L0ND0NB0Y:
I hope I'm not too late to say this but you can boot to fastbootd from fastboot with command:

for linux/mac fastboot reboot fastboot or ./fastboot reboot fastboot I have little experience in both :(

for windows "Powershell only" ./fastboot reboot fastboot this aint working for cmd for unknown reason, ig it recognize the second "fastboot" in "reboot fastboot" as an invoke to the command "fastboot" and not as a parameter sent to fastboot.exe
[OPPO Find X2 Pro Questions & Answers] L0ND0NB0Y:
use the command above to boot to fastbootd, but beware not to flash the partitions to the A slot as it's the active one ig. You have to switch to slot B before flashing and switch it again to A afterwards.

use command fastboot getvar all and look for "current-slot" in the result.

if "current-slot" is A, then use command fastboot set_active b

or if it's B then fastboot set_active a

Then switch the slot back as it was before.

Good luck with it :)
[OPPO Find X2 Pro Questions & Answers] lebigmac:
This whole slot _a/_b and super partition thing is super confusing right?

To flash super partition you can do

fastboot flash super super_patched.img

And as @L0ND0NB0Y already mentioned you can easily switch boot slots like this:

fastboot --set-active=b

Good luck!

If anyone knows where I could upload the N986BXXU1ATGI firmware aside from MEGA, kindly let me know. Or you can upload and share, too!

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For those who want the built-in Call Recorder feature, these CSC's have them:

INS

THL

SLK

XXV

Be warned though that if you change your CSC, some of your service provider's features may not work properly. Do it at your own risk.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

A favor to ask from those who successfully changed their CSC using this process. Can you kindly check with the default Caller App if the *#272*IMEI# code now works? I will update this list.Thanks!

1. XTC (Pre and with Sept 1 Update) works

2. THL (Pre and with Sep 1 update) does NOT work (thank you @ChoSmile)

Great tutorial. When I completed mine earlier this morning I didn't need to disconnect the Internet. Was that just a precaution you took?

I'll have a link ready for the firmware that people can use soon. Its the INS version but all CSC's are in there if you want me to share.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] BlinkThinks:
Yes. I don't feel safe running the CSC Changer App. Hence I made sure it did not connect to the internet.

Kindly share the faster link for the firmware so we could help everyone. I appreciate it. Thanks!

Hey guys, does anybody know will this method make samsung pay work? I've tried changing firmware to the country where it is supported, but odin always got stuck at super.img, I almost turned my phone to a brick.

Hi,

Hey Limey.. , that search bar is to search for the supported locked models only as per their chat support.

So, SM-N985F is likely to support CSC change.

Guys I have an international N986U1 with XAA CSC I reside in the US but sometimes have foreign sim cards for travel and many samsung apps change to the language of the sim card country. For instance my samsung app store and theme store are in Spanish.

Can I do anything about this?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] FabriMacLeod:
Hello Guys,

I have a Note 20 Ultra 5G from Korea ( SM-N986N )

It has firmware customizations from his carrier ( bootscreen animations and many useless apps )

After tried to flash a clean firmware whit Odin and nothing has changed, im going to try changing CSC through Samkey.

The question is, i don't think my firmware is an OXM Multi CSC. So how to know which CSC i should put on Samkey to get my phone unbranded ?

Many Many Thanks !
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] *Detection*:
Looks like you only have the choice of these CSC

KOO, KTC, LUC, SKC

---------- Post added at 09:22 ---------- Previous post was at 09:12 ----------

Going from sammobile site, I'd say "KOO" is the unbranded CSC
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] FabriMacLeod:
Really thanks for the fast reply !

Looking on Sammobile three of these CSC are from korean carriers.

KTC - ( KT Corporation )

SKC - ( SK Telecom )

LUC - ( LG U+ ) - ( my Note20 has this carrier customization )

So looks like KOO is the only choise to try !

Chatting with Samkey they assured me that all Note 20 models support CSC change. Im going to buy 3 credits from the seller you linked few pages back.

Finger crossed and thanks again.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] *Detection*:
Yes KOO was the one I also thought was the unbranded CSC

Good luck! :good:
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] FabriMacLeod:
OMG !! IT WORKED !

The phone rebooted with no operator logos and no extra operator apps, just basic apps from Samsung and Google.

Now the Service provider SW ver. is - KOO/KOO/KOO/LUC

Thank you very much ! I had almost lost hope, thanks to your simple steps and also for the link of the credit seller, he sent the login data within a few minutes.

Now I can fully enjoy this great phone.

I hope to be useful to the community in the future, as well as the community has been helpful to me.

Thanks again :D

Sorry for double post, i dont know if this is related but i cannot boot anymore into recovery mode.

Power + Volume Up is not working anymore, despite i hold these keys, the phone just bootup normally, the only thing i get is a small grey popup in the homescreen says:

[PDP] Back-up file detected.

Any suggest ?

Thanks
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] maxpaynezm:
Try via usb,turn off phone,connect usb cable + hold up volume
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] FabriMacLeod:
Sorry for late,

Just pressing the Volume Up key inserting the usb cable did not work, but something like this has worked.

Press Power + Volume Up key with the usb cable inserted.

The same combination without USB cable inserted did not lead to anything, but if pressed with the cable inserted with the phone switched off, ( with display showing the ring of the charge percentage ) it worked !

Thanks for the hint :good:

Hi,

I have Note 20 Ultra 5G with CSC of XME with the latest version. I want to change it to ILO (Israel). What should I do?

I should downgrade to July XME and than swotch to ILO?

Or should I downgrade and install directly the July version of ILO and than update to the latesr version?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] roip890:
Update may be gone?

I succeed to transfer my Note 20 Ultra 5G from XME to ILO (now it has the latest version of October).

I saw that there is a security update of November but when I'm trying to update my software through my phone it says it is up to date.

Anyone know what should I do?

There is a chance I won't have auto updates on my phone anymore?

Hey everyone

Not sure if this has already been asked...

I have a phone with November patch will I still be be able to downgrade to the July patch??

I don't want to trigger Knox.

Yes, you still can. No, it won't trigger Knox.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ChoSmile:
There is no need to downgrade to July to change CSC.

Here is free and easy metod to change active CSC:

Install Google Dialer and dial via it *#*#27262826#*#*, choose desired CSC and press (Install), phone will be reseted.

If there is no CSC that you want, download desired whole firmware via sammobile and flash via ODIN, then again with Google Dialer to change the active CSC.

This metod works on Android 10, not working on Android 11, but if Bootloader is still same (for SM-N986B it is still "1"

Android 11 N986BXXU1CTL5, Android 10: N986BXXU1ATJ1 ) - so it is possible to downgrade to Android 10 and change CSC via Google Dialer, then OTA to Android 11 and all works.

Personally I recommend (and use for all my phones) THL CSC - it have build in Call recorrder, Samsung Pay works and 5G works.

Knox not triggered.

Happy new 2️⃣0️⃣2️⃣1️⃣ :)

[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] ChoSmile:
No need to wait.

Download Android 10 THL, flash wiht ODIN, change with Google Dialer and update will be automatic to 11 via OTA.

Im worry that im gonna brick a phone doing downgrade ;( bow do you know that this is gonna fits to my phone ? ;) And in fact IM from Poland so my CSC is XEO - is it ok to flash rom with such csc ?;)

Hello everyone I have a n986b I used the guide and replaced csc from vgr vodafone greece to itv italy where I live. Samsung pay now works and updates too. 5G no longer works. I downgraded from 11 to 10 and reset csc vgr, 5G is not back. I put back csc itv, reflash latest firmware 11itv but 5G doesn't work. In my area there is 5g, my sim on another 5G mobile phone works.

I managed to downgrade to Android10 using the INS July Firmware provided on the first post. I changed CSC with google dialer and now it is SEE/SEE,SEE/XME

Unfortunatelly when I check for software update nothing comes up :) which means I could be stuck to Android 10 or there is something else I should do?

p.s EDIT: however I changes CSC to BTU (or DBT) and updates resumed :) so I guess it was something related only to the CSC i had chosen (SEE).

downgrading still works and you can reflash your note via odin with the newest firmware and keeping your csc changed branding

Is RCS working for you in Samsung messages? I had to enable it using alliance shield and still it shows only sms when writing message to someone who uses RCS.

Otherwise THL is best csc it has callerID,recording but thankfully it doesn't have the useless places tab in dialer.

I use RCS with Goolge Messages app.I try Samsung Messages on Samsung S21U XXV and Samsung N20U THL - but on both did not able to send RCS or other phones (with Google Messages and RCS) did not see them as RCS capable. So continue to use Google Messages.

THL will stop Samsung Pay on the end of 2021, other thing will work.

Good afternoon,

Currently I'm on the april update Android 11, with the H3G software. i want to switch the csc to btu to remove the three bloatware and boot screen. Could someone help me?
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] sivuha0101:
For people who can't switch between csc in the same mult csc pack. OXM multi csc pack contains all the european generic and network branded firmware (csc) so if You are at H3G (part of OXM multi pack), and flash it with BTU (part of OXM multi pack) the H3G will stay. What you need to do is to flash it with different multi csc pack (just see what packs are available for your model), try to flash it with Brazil, csc ZTO, it's part of multi pack OWO, then flash it back with OXM multi pack, and it should switch to some generic csc, then if you instert your sim card it should ask you if you want to customize your phone to the inserted sim card and it will change your csc to the one you want.
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Nizam_A:
thanks so much i did just as you said. the 3 logo boot screens gone and the apps that come pre installed. i chose to flash dbt software as i heard they get installs a bit quicker. will i get ota updates now? btw it didnt ask me about customising my phone after using a uk vodafone sim, it did install the my vodafone app tho automatically
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] sivuha0101:
What is the first CSC in Network Provider info in your software settings? You will get OTA updates
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] sivuha0101:
Looks good, but in case you want to get btu you would have to factory reset your phone, insert the english simcard in, wait around 10 seconds for the window to pop out and that would reset your phone to BTU customization
[Samsung Galaxy Note 20 Ultra Guides, News, & Discu] Nizam_A:
So right now what without resetting what updates am I having. I just got everything back 😅.
