Samsung Galaxy Note20 Ultra 5G SM-N986B/DS Firmware (Flash File) Drivers, Tools & Guide

Installing stock software on a Samsung phone using Odin is a simple process when you have the correct files. This page provides the exact Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware, the proper Odin version, and the steps that actually work.

Before starting, sign out of your Samsung account. Skipping this step triggers Knox security, leaving you with a KG lock that takes extra time to clear. Also, remember that Samsung packages use a .tar.md5 format. Once you extract the main folder, look for files labeled AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). Missing these means you downloaded the wrong package.

The Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware arrives as a compressed ZIP archive. Extract it using WinRAR or 7-Zip. You should see files named like AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If these are missing, the package is incorrect for your phone.

Flashing stock software intentionally wipes all data to resolve software issues. This process fixes FRP locks, app crashes, sluggish performance, forgotten screen locks, logo freezing, connectivity bugs, battery drain, and soft brick conditions.


Hard Reset Samsung Galaxy Note20 Ultra 5G SM-N986B/DS

To factory reset the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS without a PC, turn the phone completely off, then press and hold Volume Up + Power until the recovery menu loads. Use the volume buttons to highlight “Wipe Data/Factory Reset” and press the Power button to confirm.

A factory reset wipes all personal data and returns the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS to its original factory settings. This step resolves most software glitches, including sluggishness, system crashes, forgotten passwords, and continuous bootloops. If problems remain after the reset, the full Odin installation guide below will help.


Samsung Galaxy Note20 Ultra 5G SM-N986B/DS FRP Bypass

The most effective method to bypass FRP on the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS involves using a free Android apps launcher to access settings during the initial setup. Following a factory reset or software installation, a Google account lock (FRP) might appear. You can use our free Android apps launcher to get past it quickly. Removing your Google account before wiping the phone prevents this issue entirely.


Why Do We Need Samsung Galaxy Note20 Ultra 5G SM-N986B/DS Firmware?

Choosing the Right Firmware Version

Selecting the correct software version is critical before beginning the installation. Flashing the wrong file creates problems that are difficult to fix:

  1. Identify Your Exact Model Number: Open Settings › About Phone and check the full model number (e.g. SM-N986B/DS). The letter at the end indicates the region, U/U1 is USA, W is Canada, N is Korea, and B/F is Global. Installing files meant for another variant causes errors.
  2. Match the CSC (Region): The firmware filename includes a 3-letter region code that must match your phone. Find your current CSC under Settings › About Phone › Software Information or check the Service Provider line in Download Mode. Examples include XAA (US), BTU (UK), INS (India), and SER (Russia).
  3. Check the Binary Level: Look at the version string in your current software (e.g. XXU9BZDP, the number after the letters represents the binary level). Downgrading to a lower binary level is blocked. If your phone runs Binary 9, you must install Binary 9 or higher.
  4. Confirm the Build Date: The last 4 characters of the PDA version indicate the build date. The first character is the year (A=2024, B=2025, C=2026), and the second is the month (A=Jan through L=Dec).
  5. Verify in Download Mode: Turn off the phone and hold Volume Down + Power to enter Download Mode. This screen displays your exact model, CSC, and current software version to verify before you proceed.

Which Firmware Version Should I Download?

Choosing the right software version depends on the specific issue your phone is experiencing. Find your current situation in the table below to identify the correct file:

Your Situation What I Recommend
Phone is completely dead or stuck on logothe latest version, download this one. It is the latest Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware available.
FRP / Google account lock onlySee the FRP bypass guide above, you likely do not need the full firmware for this.
Not sure which region/CSC to downloadCheck Settings › About Phone › Software Information for your current CSC, or enter Download Mode (Volume Down + Power), it shows the CSC on screen. Match the 3-letter code (e.g. XAA, BTU, INS) to the firmware filename.
Phone slow after a recent OTA updateTry the next older version, sometimes the latest OTA introduces new bugs and an older build runs better. Make sure the binary level is the same or higher than what your device currently has.
IMEI missing after a previous flashRe-flash the latest version first, then follow the IMEI repair guide. Do not skip the reflash.
the latest version failed with a flash errorTry the next older version instead and double-check your AP/BL/CP/CSC file assignments in Odin before assuming the firmware is the problem.
Restoring to factory / warranty repairthe latest version, clean state, fresh start.

To determine which Samsung software is newer, check the last 4 characters of the PDA version string (e.g. S938BXXU9CZDP). The first character represents the year (A=2024, B=2025, C=2026), the second represents the month (A=Jan, B=Feb… L=Dec, Z=final stable), and the final two represent the revision (0-9 then A-Z, where Z is highest). Always verify the binary level before comparing dates: the digit before the date code (e.g. XXU9CZDP = Binary 9). Downgrading to a lower binary level is impossible. If your phone operates on Binary 9, install Binary 9 or higher. Ensure the 3-letter CSC code matches your region.

Prerequisites for Samsung Galaxy Note20 Ultra 5G SM-N986B/DS Firmware

Prepare these items before opening Odin to install the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware. Two common issues disrupt Samsung installations: failing to sign out of a Samsung account (which triggers KG lock) and using a low-quality USB cable that drops the connection. Always use a proper data cable.

  1. Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers now. You will need these if you need to restore your IMEI after flashing.
  2. Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
  3. Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
  4. Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
  5. Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
  6. USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
  7. Install Required Drivers:

How to Install Firmware on Samsung Galaxy Note20 Ultra 5G SM-N986B/DS

Installing software on the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS requires Odin and the correct firmware files loaded into the proper slots. This guide uses Odin. Leave “Auto Reboot” and “F. Reset Time” checked in Odin for the cleanest result. Check our Odin versions page if you need help selecting a version.

  1. Download and Extract:
    • Download the correct package and extract the ZIP to a simple folder path without spaces or special characters.
  2. Install the Listed Drivers:
    • Confirm all drivers listed above are installed and restart your PC. Skipping the restart often causes driver failures.
  3. Load the Firmware File:
    • In Odin, click “BL” and select the BL_*.tar.md5 file. Click “AP” and select the AP_*.tar.md5 file. Repeat for “CP” and “CSC”. Use HOME_CSC to keep data, or CSC for a clean wipe.
  4. Connect Your Device:
    • Enter Download Mode by turning off the phone and holding Volume Down + Power until the warning screen appears. Press Volume Up to confirm. Connect the phone to your PC. Odin will display “Added..” in the log area when detected.
  5. Start Flashing:
    • Click “Start” to begin. Do not touch the cable or device until the process finishes. Disconnecting early will brick the phone.
  6. Wait and Reboot:
    • Disconnect the device once Odin shows “PASS.”. Power it on. The first boot takes up to 8 minutes.

What to Expect After Flashing Samsung Galaxy Note20 Ultra 5G SM-N986B/DS Firmware

A successful Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware installation will trigger a few normal behaviors during the first boot. Here is what to expect:

  • How to know the flash was successful: Odin displays “PASS.” in green text at the top-left of the log area.
  • First boot takes 3 to 8 minutes: The operating system is configuring itself. Do not force a restart, or you risk a bootloop.
  • The phone will feel warm during first boot: This is normal and settles down after the initial setup finishes.
  • All your apps are gone: This is expected. Reinstall them from the Play Store. A previous Google backup will offer to restore them automatically.
  • Dial *#06# immediately after setup: Check your IMEI before inserting a SIM card. If it reads “unknown” or “null”, follow the IMEI repair guide first.
  • Be careful when re-adding your Google account: If you skipped the removal step before flashing, an FRP prompt might appear. Add the account fresh during the setup wizard.
  • Wi-Fi, Bluetooth, and mobile data: These should work immediately. If mobile data fails, manually re-enter your APN in Settings › SIM and Network.
  • Stuck in a bootloop after first boot? Enter recovery mode and perform a factory reset (see the hard reset guide above). This clears leftover data from the old system.
  • Samsung Smart Switch: After installing the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware, Smart Switch might prompt you to install extra updates. Allow it to finish to ensure you have the latest security patches.

Missing IMEI or Corrupt Baseband on Samsung Galaxy Note20 Ultra 5G SM-N986B/DS After Flashing?

A missing IMEI or corrupt baseband on the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS usually stems from a corrupted EFS partition. This partition holds your IMEI and carrier details. Restoring an IMEI that does not belong to the original device is illegal in most regions, so only restore the number the phone had previously. Software like ChimeraTool or BFT can fix this. Check local regulations before proceeding.

Common Issues When Flashing Samsung Galaxy Note20 Ultra 5G SM-N986B/DS

  1. Odin Shows “FAIL” Instead of “PASS”:
    • This indicates a mismatch between the software region and your phone. Verify your exact model number in Settings › About Phone before selecting files.
  2. Samsung Galaxy Note20 Ultra 5G SM-N986B/DS Not Recognized by Odin:
    • Reinstall the Samsung USB drivers and ensure the phone is in Download Mode. Try a different USB cable, as Odin is sensitive to cable quality.
  3. KG Lock / Knox Triggered After Flashing:
    • This occurs when a Samsung account remains signed in or unofficial software is used. Sign out of all Samsung accounts before starting. Professional tools are usually required to remove an active KG lock.
  4. Boot Loop After Flashing:
    • Enter recovery mode (Volume Up + Power) and perform a factory reset. This deletes leftover files from the previous system that cause conflicts.

Frequently Asked Questions

Q1: Will flashing the Samsung Galaxy Note20 Ultra 5G SM-N986B/DS firmware erase my data?
A: Yes. Using Odin to install this software resets the device to factory settings, including the default configurations for Android 10, upgradable to Android 13, One UI 5.1.
