The official Samsung Galaxy S20+ SM-G985F/DS firmware is the standard solution for resolving software faults on this model. This guide provides the necessary flash files, drivers, and step-by-step instructions for performing a hard reset, bypassing FRP, or repairing IMEI issues.
Device: Samsung Galaxy S20+ SM-G985F/DS | Chipset: Samsung Exynos 990 (7 nm+) | Flash Tool: Odin
Android: Android 10, upgradable to Android 13, One UI 5 | File Type: .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin)
⚠ Warning: Flashing erases all data. Back up first.
Samsung Galaxy S20+ SM-G985F/DS Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a reliable process when the correct files are used. This page contains the official Samsung Galaxy S20+ SM-G985F/DS firmware, the necessary drivers, and clear instructions for resolving common issues.
Before you begin, sign out of any Samsung accounts on the device. This prevents the activation of Knox security, which complicates the process if left active. Samsung firmware comes in a compressed ZIP format; extracting it reveals separate files named AP_*, BL_*, CP_*, and CSC_*. These files are required for the Odin flash process.
The Samsung Galaxy S20+ SM-G985F/DS firmware is distributed as a ZIP archive. You must download and extract this file using WinRAR or 7-Zip. After extraction, the folder should contain files named AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If these files are missing, you have the wrong firmware package for this device.
Keep in mind that flashing stock firmware wipes all data. This is necessary to resolve software glitches including FRP lock, application failures, sluggish performance, forgotten pattern locks, a dead or logo-stuck device, Wi-Fi and Bluetooth issues, battery drain, and soft brick situations.
Hard Reset Samsung Galaxy S20+ SM-G985F/DS
To factory reset the Samsung Galaxy S20+ SM-G985F/DS without a computer, power off the device completely. Then, hold Volume Up + Power (or Volume Up + Home + Power on older models) until the recovery menu appears. Use the volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.
A hard reset erases all user data and restores the Samsung Galaxy S20+ SM-G985F/DS to its original factory state. This fixes most software problems, slow performance, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a full firmware flash using Odin is covered in the following sections.
Samsung Galaxy S20+ SM-G985F/DS FRP Bypass
The most efficient way to bypass FRP on the Samsung Galaxy S20+ SM-G985F/DS is to utilize a free Android apps launcher that allows access to settings during the setup wizard. After flashing or performing a factory reset, you may see a Google account lock (FRP). Our free Android apps launcher provides the quickest method to get past it. This is why removing your Google account before flashing is highly recommended, it avoids this problem entirely.
Why Do We Need Samsung Galaxy S20+ SM-G985F/DS Firmware?

Choosing the Right Firmware Version
Identifying the correct firmware variant is critical to avoid bricking the device. Flashing the wrong file can cause significant problems that are difficult to recover from.
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. SM-G985F/DS). The letter suffix matters, U/U1 = USA, W = Canada, N = Korea, B/F = International/Global. Flashing firmware built for a different variant can cause issues.
- Match the CSC (Region): The 3-letter region code in the firmware filename must match your device. Check Settings › About Phone › Software Information for your current CSC, or look at the Service Provider line in Download Mode. Common codes: XAA (US), BTU (UK), INS (India), SER (Russia).
- Check the Binary Level: Look at the version string in your current firmware (e.g.
XXU9BZDP, the number after the letters is the binary level). You cannot downgrade to a lower binary level. If your device is on Binary 9, only flash Binary 9 or higher firmware. - Confirm the Build Date: The last 4 characters of the PDA version encode the build date, first character is the year (A=2024, B=2025, C=2026), second is the month (A=Jan through L=Dec).
- Verify in Download Mode: Power off, hold Volume Down + Power to enter Download Mode. This screen shows your exact model, CSC, and current firmware version, use this to confirm before flashing.

Which Firmware Version Should I Download?
Determining the right file requires checking the device’s current CSC and binary level. This table helps clarify which version to select based on the specific problem.
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | the latest version, download this one. It is the latest Samsung Galaxy S20+ SM-G985F/DS firmware available. |
| FRP / Google account lock only | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| Not sure which region/CSC to download | Check 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 update | Try 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 flash | Re-flash the latest version first, then follow the IMEI repair guide. Do not skip the reflash. |
| the latest version failed with a flash error | Try 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 repair | the latest version, clean state, fresh start. |
To tell which Samsung firmware is newer, look at the last 4 characters of the PDA version string (e.g. S938BXXU9CZDP). The first character is the year (A=2024, B=2025, C=2026), the second is the month (A=Jan, B=Feb… L=Dec, Z=final stable), and the last two are the revision (0-9 then A-Z, where Z is highest). But before comparing dates, always check the binary level: the digit just before the date code (e.g. XXU9CZDP = Binary 9). You cannot downgrade to a lower binary level. If your device is on Binary 9, only flash Binary 9 or higher. Also make sure the 3-letter CSC code in the firmware matches your device region.

Prerequisites for Samsung Galaxy S20+ SM-G985F/DS Firmware
Ensure these conditions are met before you open Odin for the Samsung Galaxy S20+ SM-G985F/DS. Two common issues with Samsung devices are a Samsung account that was not signed out before flashing, which can trigger KG lock, and a USB cable that works for charging but drops the connection mid-flash. Always use a proper data cable, not a charge-only cable.
- 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.
- Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
- Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
- USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
- Install Required Drivers:
How to Install Firmware on Samsung Galaxy S20+ SM-G985F/DS
We are using Odin for this. A quick tip: keep “Auto Reboot” and “F. Reset Time” both checked in Odin, those two options together give you the cleanest flash result. If you are not sure which Odin version to use, check our Odin versions page. Some older Samsung devices work better with older Odin builds.
- Download and Extract:
- Download the correct firmware package from the links above.
- Extract the ZIP to a simple folder path, avoid paths with spaces or special characters, as some flash tools have trouble with them.
- Install the Listed Drivers:
- Confirm all drivers listed above are installed and that your PC has been restarted since installation. Skipping the restart is a common reason drivers do not work correctly.
- 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 flash.
- Connect Your Device:
- Enter Download Mode: Turn off your phone, then hold Volume Down + Power (add Home button on older models) until the warning screen appears. Press Volume Up to confirm and enter Download Mode.
- Connect your phone to your PC via USB. Odin should show “Added..” in the log area, this means your device is detected.
- Start Flashing:
- Click the “Start” button to begin.
- Do not disconnect, move the cable, or touch the device until the process is fully complete. Disconnecting mid-flash is how devices get bricked.
- Wait and Reboot:
- Once flashing finishes successfully, disconnect the device.
- Power on your device. The first boot will take longer than usual, give it up to 8 minutes.

What to Expect After Flashing Samsung Galaxy S20+ SM-G985F/DS Firmware
I get a lot of comments from people who think something went wrong when it actually did not. Here is what is completely normal after a successful Samsung Galaxy S20+ SM-G985F/DS firmware flash:
- How to know the flash was successful: Odin will show “PASS.” in green text at the top-left of the log area. If you see this, everything went fine.
- First boot takes 3 to 8 minutes, do not force-reboot the device. The operating system is setting itself up from scratch. Interrupting this is how devices end up in bootloops.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- All your apps are gone, this is expected. Reinstall them from the Play Store. If you had a Google account backup active, it will offer to restore your apps automatically during setup.
- Dial *#06# immediately after setup to check your IMEI. Do this before you insert a SIM card. If it shows “unknown” or “null”, follow the IMEI repair guide below before doing anything else.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
- Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings › SIM and Network and re-enter your APN manually, the flash sometimes clears carrier APN settings.
- Stuck in a bootloop after first boot? Enter recovery mode and do a factory reset from there, see the hard reset guide above. This can happen occasionally and does not mean the firmware is wrong, it is usually a conflict with leftover data from the old install.
- Samsung Smart Switch: After flashing your Samsung Galaxy S20+ SM-G985F/DS firmware, Samsung Smart Switch may prompt you to install additional updates. Let it complete, this ensures your device has the latest security patches for your region.
Missing IMEI or Corrupt Baseband on Samsung Galaxy S20+ SM-G985F/DS After Flashing?
A missing IMEI on a Samsung device after flashing usually points to a corrupted EFS partition, this is the partition that stores your IMEI and carrier settings. Note that restoring an IMEI that is not your original number is illegal in most countries, so only do this if you are restoring the number the device had before you flashed. Tools like ChimeraTool or BFT can help with this. Check your local laws before proceeding.

Common Issues When Flashing Samsung Galaxy S20+ SM-G985F/DS
- Odin Shows “FAIL” Instead of “PASS”:
- This is usually a mismatch between the firmware region or model and your device. Confirm your exact model number in Settings › About Phone before selecting the firmware. Even a single letter difference in the model code matters.
- Samsung Galaxy S20+ SM-G985F/DS Not Recognized by Odin:
- Reinstall the Samsung USB drivers. Make sure you are in Download Mode. Try a different USB cable, Odin can be sensitive to cable quality.
- KG Lock / Knox Triggered After Flashing:
- This happens when a Samsung account was still signed in before flashing, or when unofficial firmware was used. Always sign out of Samsung accounts before flashing. If KG lock is already active, a professional unlocking tool is generally needed.
- Boot Loop After Flashing:
- Enter recovery mode (Volume Up + Power) and perform a factory reset. This clears any leftover data from the previous firmware that may be causing the conflict.
Frequently Asked Questions
Q1: Will flashing the Samsung Galaxy S20+ SM-G985F/DS firmware erase my data?
A: Yes, flashing this firmware with Odin restores your device to factory state, including Android 10, upgradable to Android 13, One UI 5 default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
Q2: Is this firmware compatible with other Samsung models?
A: No. This firmware is built specifically for the Samsung Galaxy S20+ SM-G985F/DS running on the Samsung Exynos 990 (7 nm+) chipset. Even the Galaxy S20+ with a different letter suffix (for example, a different variant of SM-G985F/DS) can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings › About Phone.
Q3: Can I downgrade from the latest version to an older firmware version?
A: It is technically possible on some Exynos builds, but I do not recommend it. Downgrading can cause security issues and app compatibility problems on Android 10, upgradable to Android 13, One UI 5. If the latest version is causing you trouble, leave a comment below, there is usually a better fix than rolling back.
Q4: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock on the Samsung Galaxy S20+ SM-G985F/DS activates when a Google account was still signed in before flashing. This is also why I always recommend signing out of your Google account before flashing, it avoids this issue entirely.
Q5: Are custom ROM options available for the Samsung Galaxy S20+ SM-G985F/DS?
A: This guide covers official Samsung stock firmware only. Custom ROM availability for the Samsung Galaxy S20+ SM-G985F/DS depends on whether the Samsung Exynos 990 (7 nm+) chipset has open-source kernel support. Check our Custom ROMs page or the XDA Developers forum for device-specific custom ROM threads.
Q6: My Samsung Galaxy S20+ SM-G985F/DS is not detected by Odin. What should I do?
A: Start with the drivers, reinstall the Samsung USB drivers, restart your PC, then try again. Switch to a USB 2.0 port if you are on USB 3.0, Samsung devices are more reliable on USB 2.0 ports. Disable your antivirus temporarily. If none of that works, leave a comment below with the exact error message and I will help you from there.
Q7: How do I enter recovery mode on my Samsung Galaxy S20+ SM-G985F/DS?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. For older Samsung models with a physical Home button, use Volume Up + Home + Power. The recovery menu will display the build number for your Samsung Galaxy S20+ SM-G985F/DS which you can use to verify your firmware version before flashing.
Q8: My IMEI shows “unknown” after flashing the Samsung Galaxy S20+ SM-G985F/DS. Is my phone permanently damaged?
A: No, it looks alarming, but it is fixable. Follow the IMEI repair guide in the troubleshooting section above. For Samsung devices, check for EFS partition corruption first. The important thing: do not insert a SIM card until the IMEI is restored.
Q9: How long does it take to flash Samsung Galaxy S20+ SM-G985F/DS firmware?
A: The actual flashing process usually takes between 3 and 10 minutes depending on the firmware size and your USB connection speed. The first boot after flashing takes longer, anywhere from 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in Odin appears stuck, give it a few more minutes before assuming something went wrong.
