Restoring the Samsung Galaxy Tab S8+ SM-X800 to a working state usually requires the official firmware. I have gathered the necessary files and instructions here to help you get the device running smoothly again.
Device: Samsung Galaxy Tab S8+ SM-X800 | Chipset: Qualcomm Snapdragon 8 Gen 1 (SM8450) | Flash Tool: Odin
Android: Android 12, One UI 6.1.1 | File Type: .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin)
⚠ Warning: Flashing erases all data. Back up first.
Samsung Galaxy Tab S8+ SM-X800 Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a standard procedure that goes smoothly if you follow the steps carefully. I have put together the right files and instructions for the Samsung Galaxy Tab S8+ SM-X800 firmware on this page.
Before you begin, it is important to prepare your device. If a Samsung account is still signed in, sign it out before proceeding to avoid triggering the Knox security feature. Also, verify that the firmware files are named correctly. You should see files labeled AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*) after extracting the ZIP. If the names do not match, you have the wrong package.
The Samsung Galaxy Tab S8+ SM-X800 firmware comes as a ZIP archive. You must extract this file using a program like WinRAR or 7-Zip. Once extracted, look for the specific file names: AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5. If you do not see these specific extensions, the download is likely incorrect.
Keep in mind that flashing stock firmware erases all data, which is intentional, as it resolves software issues including FRP lock, app problems, slow 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 Tab S8+ SM-X800
To perform a factory reset without a computer, turn the device off completely. Then, press and hold Volume Up and Power at the same time 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 data and restores Samsung Galaxy Tab S8+ SM-X800 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 Tab S8+ SM-X800 FRP Bypass
The quickest way to bypass the Google account lock is to use a third-party app launcher that allows access to the settings menu during the setup process. Our free Android apps launcher is designed for this exact purpose. This method is much faster than other solutions and is the reason I always advise removing your Google account before flashing.
Why Do We Need Samsung Galaxy Tab S8+ SM-X800 Firmware?
Samsung devices are flashed using Odin regardless of the specific chipset inside. Using the official firmware is the best way to resolve software issues. Here is why you might need it:
- Unlock your device if it has been locked or disabled.
- Update to the latest Android version supported by your phone.
- Fix startup loops, lagging, and freezing on your SM-X800 Galaxy Tab S8+.
- Resolve OTA update failures and battery drain issues.
- Restore the original Samsung stock ROM to keep your warranty valid.
- Recover your device when it only boots into recovery mode.
- Recover from KG lock or Knox-related issues after an incorrect or interrupted flash on your device.

Choosing the Right Firmware Version
Selecting the correct file is crucial before starting the process. Flashing the wrong firmware can lead to significant issues that are hard to resolve.
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. SM-X800). 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.
Firmware Details for Samsung Galaxy Tab S8+ SM-X800
Here is a quick overview of the official firmware specifications:
| Firmware Information | Details |
|---|---|
| Device Model | Samsung Galaxy Tab S8+ SM-X800 |
| Firmware Version | N/A |
| File Size | N/A |
| Android Version | Android 12, One UI 6.1.1 |

| Region | Global, Africa and Asia |
| File Type | .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin) |
Which Firmware Version Should I Download?
This is a common question, so I have created a simple guide. Find your specific situation in the table below to find the right file:
| 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 Tab S8+ SM-X800 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.
Download Samsung Galaxy Tab S8+ SM-X800 Firmware
You can download the latest available version of the official stock firmware below. It is important to verify that the file size matches the specifications listed above. If the size is different, the file may be corrupt or incomplete.
Only download firmware that is fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
- Your model number is a variant of SM-X800 with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Qualcomm Snapdragon 8 Gen 1 (SM8450). Confirm in recovery mode before proceeding.
- You downloaded the file from a source other than this page.
- The file size differs significantly from the sizes listed in the table above, a size mismatch usually means a partial download, which will fail mid-flash.
Prerequisites for Samsung Galaxy Tab S8+ SM-X800 Firmware
Before you launch Odin, check this list. Two common causes of problems are a Samsung account that was not signed out and a USB cable that is not stable. Always use a proper data 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 Tab S8+ SM-X800
We will use Odin for this process. For the best results, ensure “Auto Reboot” and “F. Reset Time” are both checked. These settings help ensure a clean flash. 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 Tab S8+ SM-X800 Firmware
Many users worry when the phone does not turn on immediately. Here is what is normal after a successful Samsung Galaxy Tab S8+ SM-X800 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 Tab S8+ SM-X800 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 Tab S8+ SM-X800 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 Tab S8+ SM-X800
- 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 Tab S8+ SM-X800 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 Tab S8+ SM-X800 firmware erase my data?
A: Yes, flashing this firmware with Odin restores your device to factory state, including Android 12, One UI 6.1.1 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 Tab S8+ SM-X800 running on the Qualcomm Snapdragon 8 Gen 1 (SM8450) chipset.
