If i've set my lockscreen to pin code or fingerprint. My phone will switch between samsung logo and screen lock very fast. If i can't unlock it during the very short time with my pin code or fingerprint, i can't boot in the system… and it will reboot then turning to a boot loop.

So you're saying that after you restart your phone, it shows you the lock screen for only a few seconds, and then if you can't unlock it, it automatically reboots? Without you trying to reboot it? Can you please post a video of this so we can better understand the problem?

Did you flash stock rom via ODIN? If so, did you use the correct rom based on your CSC?

Yes,with the "correct" stock rom which is BRI G9980 rom. I even flashed CHC rom for china,and everything works fine like it should be. I've tried all three G9980 stock roms,TGY rom has the same issue. Don't know what's the point is between CHC stock rom and the other two. CHC rom is safe from bluetooth gear pairing and Lockscreen issue,and BRI.TGY not that lucky.

did you ever figure out what the problem was?

Managed to revive it by doing the following:
1. Download the stock ROM from http://forum.xda-developers.com/showthread.php?t=1350500
2. Use Odin to restore to the stock ROM.
3. Restore to any other of your choice ROM.
Hope this helps someone!

Sim = reboot

Hey guys.
Long story short, Galaxy Mini reboots itself when it gets signal. So without sim card it works flawlessly. Or when the sim is in and I dont type the pin code. When a friend borrowed me the phone it was rooted with stock rom and some kernel on it. And it worked. Now I flashed back stock 2.3.6
firmware and now EVERYTHING is STOCK. And the problem appeared when i did a clean flash. Why would that be? And how to fix it? Please guys help me. I donw know what to do anymore. I tried other stock 2.3.6, but other country and same thing. It reboots or its just black screen after pin input (5-10sec)

So, you're using PIN Lock on your SIM ?
If so, then try to disable the PIN lock.

Question Call Recording

Hi!
Is there any solution without rooting for good quality call recording on S21 Ultra?
Okay, i know it google disabled this function since android 9/10. But on Mate20Pro there is an apk thats working on android 10 with good quality,recording microphone and incoming voice.
Every apps i tried works only on microphone side. Incoming voice is weak and bad quality, its only recorded through microphone if you set up the volume.
Any solution? Thanks!
I am also in your situation, I tried to flash with ODIN firmware THL but nothing to do, the phone always remains with csc OMN, unusable for me without call recorder, thanks for suggesting a solution.
Call Recorder - Record Phone Calls From the Line (skvalex.com)
Have you tried that yet? Works perfectly on my S20 Ultra, but haven't (yet) set up my S21 Ultra, so haven't tried it.
it's the program I've been using for 4 years. I bought the full version, but without the native recorder you can't hear the voice on the other side
Not working...

the only solution for me till now , is to flash XID home csc that will not wipe ur mobile .
i have exynoss s21 ultra , my csc was MID/MID/MID/XSG
now its XID/XID/XID/XSG
i got ota update.
and my csc was oxm multi csc .
xid not multi csc its OLE csc .
that why it work for me , THL not work coz its multi oxm csc same xsg or mid so will nit change till u use THL sim card.
the problem is that whatever firmware I try to flash with ODIN it seems that the phone does not see it and remains with previous firmware, I notice this because the progress bar never reaches the end and restarts first restarting with oxm firmware

@peppegrecio
Does the Skvalex Call Recorder now work?
Yes
Could you please post a link to the XID HOME_CSC
Is that the only file that needs to be flashed?
My current CSC is BTU/BTU,BTU/EUX/BTU ... will the XID work ?
Thank you
I'm here to report that thanks to @carlitobahsoun I was able to get native call recording working.
The steps are as follows.
1. Download the Indonesian firmware. You can download it from Sammobile here and I uploaded it to MEGA here
2. Download Odin tool. from same page on Sammobile or MEGA here
3. Unpack both files.
4. Run Odin and attach the files on the right side as shown in the attached image. Note, in the CSC field, If you want to keep your data and not format your phone use HOME_CSC. To format it use CSC_.
I used HOME_CSC.
5. Put the phone in DFU mode. While the phone is unplugged and adequately charged and completely off. Plug the USB to your PC, then hold both volume buttons and then plug the USB .
6. Click Start. It will take some time and should say Pass in green color and it will reboot automatically.
That's it.

I'm a total newb, so please excuse my ignorance. I'm on a Verizon s21U in the U.S. Do I need to root to do this? Adding this feature does not wipe anything on the phone? (It's new, so not a major issue, but I'd have to reload apps and configure everything again, which I'd gladly do for call recorder to work again.) Thanks very much!

[Guide] How to convert s10-g973N to sm-g973f, change csc from skc to koo or any another, fix emergency calls only. No need of paid apps, boxes etc.

**********This is first time am posting a guide so pardon me. *******
********As usual am not responsible for anything that happens to your phone.*******
*****Am not claiming ownership of the above technique, its what worked for me*****
I saw many posts here about people struggling to change csc from skc to koo or international***
Others had issue with their phone suddenly lost network and just displays emergency calls only****
so I have s10 sm-g973n which had csc as koo then flashed skc my mistake. The phone booted with annoying skc boot logo, and branded junk from the carrier. Then one morning the phone couldn't connect to gsm network!
I tried all manner of things to fix it. Rooted with magisk, flashed custom rom nothing.
Tried samkey to change csc still nothing. modified odin in flashing multi csc rom nothing.
Got some luck in changing csc by editing efs/imei/mps_code.dat using root explorer, text editor and vola the carrier junk disappeared. But still no network.
was told only way is to use z3x box or chimera to patch certificate but didn't give up. I posted question here in xda but no guide or response.
But that gave me an idea of what could be the issue- corrupt efs that needs the certificate to be patched. so got keyword.
After watching many YouTube videos I came across a video about a rom that has certificate patched. Just flash with odin and done!
I downloaded and followed the instructions. The phone booted up fine and after going through initial setup the network was back!
Not only did the network came back but the model changed to F, csc became oxm! You can now use tools like Samfw from too to change csc to your local region.
Later in the day, will be flashing firmware with my region csc.
Here is the link to the rom:

And here is the video:
Thanks for your post. I think before do it we need back up all anything

Did you find a fix for that? For me the internal memory become 32Gb. Is there a solution for that?
I bought an S10 that turned out to be a G973N(SKC) flashed to G973F-D/S(XSG). I think they used this method and these files to do it. I can't get the OEM unlock option to come up. I've tried everything. I am starting to think that it's because of the XSG country code. I was going to try to change it XEU (Great Britain) in SamFW but it just stalls and doesn't do anything. Any suggestions on what I can do here to change the country code? I need that OEM unlock option so I can degoogle it.
Hi guys,
I have I big problem with this rom man, each time I restart my phone i lost network and I have to reflash your rom and factory reset the phone to get it back. It's like it's forbidden to restart the phone, otherwise my network get lost and IMEI Status NG again.. Is there a fix for that? Thank you. Is there a for that fix?
Or do you guys have a rom based on android 12 for g973n u7 converted to dual sim that can solve this IMei STATUS NG? I watched on youtube some guys that have it but it's not free or I can't pay that from here in my cluntry the poorest country in the world.
Thank you guys.
