Hi there

Could you go to Software Info on your device, screenshot it from top to bottom and post it here?

Thank you for your screenshots

1. Download SmartSwitch for PC (NOT to be used, just for the drivers): https://www.sammobile.com/samsung-smart-switch/
2. Download Odin 3.14.x: https://dl2018.sammobile.com/Odin3-v3.14.4.zip
3. Download latest firmware for Multi-CSC OYN: https://www.sammobile.com/samsung/ga...1CTL2/1034519/

How to flash firmware to your phone:



1. Extract (un-rar) the firmware file (i.e. to folder c:\Odin) ***

2. Download Odin v3.14.4

3. Extract Odin ZIP file (i.e. to folder c:\Odin)

4. Open Odin v3.14.4

5. Power OFF your Note20 Ultra 5G

6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone.

7. Wait until you get a blue sign in Odin

8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!

9. Make sure re-partition is NOT ticked

10. Click the start button, sit back and wait few minutes

Use SamMobile only if you are 100% sure about the risks involved in flashing your device. SamMobile is not responsible for any damage caused by using the files on this website.

I have the same exact specs as the OP, but there has been a new firmware update since this post, where can I find that one, or should I use the same one you provided?

thank you.
