Hey all,
is there any way to install a native call recorder on this SM-G991U unlocked?
I've got the same question. I would like to factory reset the phone after Android 12 update as I have some interface bugs.
But before that, I have been thinking to install Indonesia CSC like this:
CSC_OLE_G991BOLE3BUK9_CL22937332_QB46258626_REV01_user_low_ship_MULTI_CERT.tar
That should have native call recording.
Is it going to work under Android 12? Is it going to work through Odin?

Your phone is G991U or G991B?
if your phone is G991U so from what I understand you can't install G991B version
I have got G991B, straight from Samsung UK. In my opinion it should work. Maybe I will try tomorrow.
Just to let everyone know, I flashed the Indonesia full firmware and call recording is working extreamly well.

I have a question regarding this. What am I compromising when I change a CSC region to indonesia?
1. Will it void warranty?
2. Will I receive future OTA updates from Samsung? If yes, the according to which region?
Hope anyone can help me out with this.

1. No flashing via odin does not trip Knox. Even if it did in most countries now your statutory warrebty would still be valid. You could always just flash original rom back again either way.
2. Yes. You will still revive updates and for the CSC you switch to.
Flashing different official Samsung roms via Odin is standard and one of official ways of changing roms. You're not breaking any sort of terms of service.

Hi
I need stock rom, Three (3) Sweden.
I would like to downgrade but I don't think you can do that from 4.3 right?
Found a link to one version but link was broken.
Problem is that I removed the provider lock a long time ago. But for some reason it came back when I upgraded to 4.3.
Then I bought a sim unlock code from my provider but that won't work now. Probably cause the stock rom I use now is international.
Any tips?

You need to quote the original poster not me.
Also don't go giving the post when you don't understand it.
Read up on pit files and why they are a last resort. Theres a reason its called rescue or emergency firmware. Only used when the phone is soft bricked and all else has failed.

Thanks. Yes it's Tre. But as I understand it I will brick my phone if I try to downgrade from 4.3 so I'll probably just stick to 4.3 unless you know something I don't?
Anyhow, I think I will have to have the shop fix it. I managed to find the stock rom now and reflashed it but the unlock code I got from them still don't work. So I don't see any other option, I need to have it unlocked and I allready paid for it.
Thanks anyhow.

So, I did this. Pretty impressed with the overall device feel now, SE9 is nice . No hang ups other thank it took a long friggin' time, also remember this will WIPE all the data, so make sure to do a backup prior to. The initial/first phone setup is very iPhone-ish, imo.

Be warned; this update is ONLY for SM-G930A firmware - it has a second-stage updater that blocks all other versions (including SM-G930T, which I myself tried). In other words, it is a carrier-specific update, folks.

You could try flashing G930A firmware in Odin and updating that way.

If it weren't for this being a daily driver, I'd consider it. However, because it is, that's not an option. So I'll have to wait for either a neutral version or one that will work with the SM-G930T.
I am currently testing it out, I was on the latest U firmware and downloaded the latest ATT firmware, will update on how it goes

I had the same issue. The recommendation of rebooting into recovery and wiping Cache works.
:good:
Well I saw the update in France [XEF] yesterday and wanted it right then! So I searched all the forums and finally found a good way and now my unlocked Galaxy Note 8[NON Rooted] is running Oreo with INS CSC.
Made this guide so that people can find this method easily.
Keep in mind that flashing your device is always risky and I DO NOT take any responsibility if you mess up the procedure and damage your device.
Method:
>
Download the latest BRB2 Firmware from here https://updato.com/firmware-archive-select-model?record=67BFD0E620FF11E89F15FA163EE8F90B OR https://www.sammobile.com/firmwares/galaxy-note8/SM-N950F/XEF/
Flash it using Odin[3.12.3] [ MAKE SURE THAT ONLY AUTO REBOOT & F.RESET TIME options are checked in the 'Options' tab of ODIN]
After flashing is complete reboot into system and run through the setup, after that remove your SIM & SDCARD and open the phone app. Dial *#272*YOUR IMEI NUMBER# to open the list of CSCs. [to get your IMEI dial *#06#]
Select the XEF CSC, it will ask to reboot and reset the device, let it do the same.
After the device reboots then check for software updates manually and you'll get OREO.
After installing oreo put your sim and sdcard back in, it will tell you to reset the device, DO IT as its necessary to restore your original CSC.
That's it
Now you have OREO, Non rooted and stock oreo.

UK owners the only way to get XEF is with the latest COMB file N950FXXU3ARA2.
I have had this update right after turning it on for the first time, but since I insert my local sim card, it forces me to factory reset it.
Since then no update.
I contacted Samsung & they say: "you must insert a UAE sim card which is activate and working, then factory reset the device to register it back to it's original
software provider. otherwise - no pie for you.
I am not in the UAE and have no way to get such a sim card.
Just factory reset won't help much.
Any help ?

Hi all,
I ended up getting a phone from a foreign region (Taiwan - I live in the UK), since I couldn't find the 8gb version from a UK seller.
The phone came with the tamper seals broken
https://imgur.com/a/pSd9yoZ
and seemingly had a screen protector on it (I don't know if it was the factory film, but it seemed too hardy to be that).
https://www.onbuy.com/gb/unlocked-a...s-5g-dual-sim-256gb-8gb-ram~c12871~p52964453/
The phone is listed as Unlocked and New.
It seems that the seller sold a used device as new? Or would they have had to unpack the device to network unlock it?
I installed https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&gl=GB which gives a "Sorry! Root access is not propertly installed on this device." message.
Also, booting the phone in download mode gives the line: "WARRANTY VOID : 0x0", so it seems Knox hasn't been tripped.
Does this mean the phone is safe to use without fear of malware?
Will things like Samsung pay work if the phone is from a different region (with Knox still intact)?
Should I flash a fresh stock ROM? (I've never done this before)
If so, would it have to be a Taiwanese one? (with matching CSC region)
Thanks!
Arobase40 said:
The tamper seals broken is normal if the seller added a film protection...
I have no experience with phones from Taiwan, but I bought my Galaxy Note9 with 512 GB storage to a dealer from Hong-Kong but the Note9 came from an Australian carrier (unlocked though)... lol
I flashed a XEF French firmware and all is fine till now.
No need to flash a firmware from Taiwan as you can use any firmware you wish so if any malware it should be erase, and don't forget to use the normal CSC and not the HOME_CSC, so it will switch the Taïwan CSC to your UK CSC...
You can also remove most bloatwares with adb commands without being root.
But be aware Samsung Pay doesn't work in every countries of the world, so be sure it is working in your country.

Ok. But will this break Knox? Will it disable features like Samsung Pay?
How will updates be affected?
edit: the 256gb/8gb RAM model doesn't exist in the EU/UK. So if I use a UK firmware, can this cause errors? (UK has only 128GB/6GB RAM).
If you still feel insecure you can keep the Taẅan firmware but you will be on your own... ^^

What can happen if I don't flash any stock firmware?
Arobase40 said:
Since this is original and genuine firmware from Samsung, there should be not problem and no issue at all.
As I said if Samsung Pay is working in the UK, there should also be no problem !
Just use PC Odin which is also an official tool used in the official Samsung Repair centers.
As far I know Taïwan receives International firmwares.
There was also no Galaxy Note9 with 512GB storage in France and I never encounter any trouble with Samsung firmwares.

I will. I will wait to see if the seller can explain why the box was not sealed. If I do not get a reply in few days I will try flash the UK unlocked firmware (CSC: BTU). This is the correct firmware for UK (unlocked), yes?
Arobase40 said:
There are different CSC for your country but BTU should be fine with UK carrier free phone.
I don't think you should waist your time with the seal as obviously this is due to the screen protection and as "WARRANTY VOID : 0x0", but do as you wish...
Other clues to know if there were an attempt to root this phone : from the Download mode you should see :
- CURRENT BINARY : Samsung Official
- OEM LOCK : ON
- WARRANTY VOID : 0x0
Then all is fine !
But if you have :
- CURRENT BINARY : "Custom (0xxxx)
- OEM LOCK : OFF (U)
- WARRANTY VOID : 0x1
Then you are in trouble...
BTW can you confirm the actual CSC ?
Click to expand...
Click to collapse
I have all that in Download mode - so there has been no root access?
The CSC is A528BBRI1AUL2 which appears to be the 1 December 21 security update (I installed this because I thought it would be safer to connect to WiFi with the latest version).
Edit: what can happen if I keep the Taiwan CSC? You said can be problems with my phone call plan??
Arobase40 said:
If this is this one :
- CURRENT BINARY : Samsung Official
- OEM LOCK : ON
- WARRANTY VOID : 0x0
Then indeed no root access !!!
A528BBRI1AUL2 : is NOT the CSC. It should be 3 Letters or 2 letters with a number as BTU is the UK CSC...
Should be in the "Carrier software version" or something like that as I don't have an English firmware version.
About keeping Taiwan CSC, I said could be problem with your phone call plan as your actual UK carrier may think you are calling from Taïwan and may charge you extra fees... lol
This is just a hypothesis, a guess...
But come on, you have all the steps and tools to do this safely so don't be so scary...

You shouldn't be too worried about switching firmware, as long as you're doing it the right way. There might be one or two small things you'll need to set when you switch firmwares due to different configs, but you should be good to go.
Odin only flashes the firmware if it sees that everything is set right, otherwise the firmware won't be flashed which virtually removes most troubles you would otherwise face in more universal flash tools.
But do it when you feel like it, watch plenty of videos on how to do it so that you know exactly how the process goes on.
Other than that, the others have pretty much told you everything there is to know. I wouldn't worry about the broken seals since the phone looks to be on official software with Knox intact. I would flash it with a clean firmware though just to be 100% that there no nasty on it!
Edit: Since you are a newbie to this, make sure you get the right firmware for your phone. The A52 has so many variants, the A525F, A525M, A526B, A526U1, A528B and there might be more. Make sure you know your's by looking for the Model Number in the About Phone section at the foot of the settings app.

Odin only flashes the firmware if it sees that everything is set right, otherwise the firmware won't be flashed which virtually removes most troubles you would otherwise face in more universal flash tools.
But do it when you feel like it, watch plenty of videos on how to do it so that you know exactly how the process goes on.
Other than that, the others have pretty much told you everything there is to know. I wouldn't worry about the broken seals since the phone looks to be on official software with Knox intact. I would flash it with a clean firmware though just to be 100% that there no nasty on it!
Edit: Since you are a newbie to this, make sure you get the right firmware for your phone. The A52 has so many variants, the A525F, A525M, A526B, A526U1, A528B and there might be more. Make sure you know your's by looking for the Model Number in the About Phone section at the foot of the settings app.

The full model name is SM-A528BZKIBRI. How do I know if a particular CSC will be compatible?

When you use Frija, for the Model name you just have to type SM-A528B and for the CSC, type BTU, then click on Check Update. it will show you the latest firmware available. Simply click on Download and then put it in the folder of your choice.
It may take a while depending on your internet speed. You will find a zip file with 5 files inside. So you just have to unzip it, before you can use PC Odin to flash them.
In you case, you have to use the CSC_OMC_XXXXXX and not the HOME_CSC_XXXXX as you want to convert the BRI CSC to BTU CSC.

Thanks. So I can type any region's CSC as long as I put the model as SM-A528B and the files will be compatible?
Doesn't matter that BRI isn't in the same multi-csc (OXM) that BTU is in?

Pretty much yeah.

NOPE, as all CSC won't be compatible as all countries aren't using the same network frequencies and VoLTE or VoWifi aren't supported everywhere and some frequencies won't be compatible and thus won't work !
One time I downloaded and flashed an Indian firmware to get phone call recorder function and my french carrier charged me different SMS I didn't send myself !!! ^^
So I had to flash back a local firmware to get rid of this problem !!! ^^

haha. How do you know though?
Also, is it a problem that I downloaded the December Security Update already? (Now factory reset just takes it back to December update, not older).
