You can repair your SM-T870 Galaxy Tab S7 using the official Samsung Galaxy Tab S7 SM-T870 firmware. This page contains every file and tool you need, including flash files, drivers, and step-by-step instructions for FRP bypass, hard resets, and IMEI repair.
Device: Samsung Galaxy Tab S7 SM-T870 | Chipset: Qualcomm Snapdragon 865 Plus | Flash Tool: Odin
Android: Android 10, upgradable to Android 13, One UI 5.1 | File Type: .tar.md5 / ZIP (Contains AP, BL, CP, CSC files for Odin)
⚠ Warning: Flashing erases all data. Back up first.
Samsung Galaxy Tab S7 SM-T870 Firmware (Flash File) Drivers, Tools & Guide
Flashing your tablet with Odin is a straightforward process when you have the correct files and steps prepared. I have gathered everything you need right here, including the proper Odin version and the exact Samsung Galaxy Tab S7 SM-T870 firmware file.
Before you begin, make sure to sign out of any active Samsung accounts on the tablet. Skipping this step will trigger Knox security, which adds unnecessary time to the process. Official Samsung packages arrive in a .tar.md5 format. Once you extract the ZIP folder, look for the AP_*, BL_*, CP_*, and CSC_* files. If those files are missing, you have downloaded the wrong package.
The Samsung Galaxy Tab S7 SM-T870 firmware downloads as a compressed ZIP archive. You can extract it using WinRAR or 7-Zip. Inside, you will find the AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5) components.
Remember that installing stock firmware will completely wipe your tablet. This factory reset effect is intentional and clears out software glitches, FRP locks, forgotten patterns, system freezes, and soft brick conditions.
Hard Reset Samsung Galaxy Tab S7 SM-T870
You can perform a factory reset on the Samsung Galaxy Tab S7 SM-T870 without a computer by using the hardware button combination. Power off the tablet entirely, then press and hold Volume Up + Power together until the recovery menu loads. (If your tablet has a physical Home button, use Volume Up + Home + Power). Highlight “Wipe Data/Factory Reset” using the volume keys and select it with the Power button.
This hard reset wipes the internal storage and returns the Samsung Galaxy Tab S7 SM-T870 to its out-of-box state. It resolves common complaints like sluggish performance, system crashes, and continuous bootloops. If the tablet still misbehaves after the reset, flashing the full firmware with Odin is the next logical step.
Samsung Galaxy Tab S7 SM-T870 FRP Bypass
The most effective method to bypass FRP on the Samsung Galaxy Tab S7 SM-T870 involves using a free Android apps launcher to access settings during the initial setup. Factory resetting or flashing your tablet often triggers the Google account lock (FRP). You can use our free Android apps launcher to quickly get past this screen. This is exactly why removing your Google account before a reset is always a smart habit.
Why Do We Need Samsung Galaxy Tab S7 SM-T870 Firmware?
Flashing the official Samsung Galaxy Tab S7 SM-T870 firmware resolves deep system issues that a simple factory reset cannot fix. Samsung tablets rely on Odin for flashing, regardless of the internal processor. Installing the official software fixes a wide range of operational problems:
- Unlock a tablet that has been disabled or restricted.
- Upgrade the operating system to the newest available version.
- Eliminate bootloops, screen freezes, and general sluggishness on your SM-T870 Galaxy Tab S7.
- Fix battery draining rapidly or over-the-air update errors.
- Reinstall the original stock ROM to maintain warranty status.
- Fix a tablet that will only boot into the recovery menu.
- Recover from KG lock or Knox errors caused by an interrupted flash.

Choosing the Right Firmware Version
Selecting the correct firmware version for your tablet prevents permanent damage and ensures a successful flash. Take a moment to verify your files before opening Odin. Installing the wrong package creates problems that are hard to undo:
- Identify Your Exact Model Number: Open Settings › About Phone and check your model (e.g., SM-T870). Pay attention to letter suffixes, U/U1 is USA, W is Canada, N is Korea, and B/F is International. Different variants require different files.
- Match the CSC (Region): The 3-letter region code in the firmware name must align with your tablet. Find your current CSC under Settings › About Phone › Software Information or check the Download Mode screen. Examples include XAA (US), BTU (UK), INS (India), and SER (Russia).
- Check the Binary Level: Look at your current version string (e.g.,
XXU9BZDP). The number after the letters represents the binary level. You cannot downgrade past this number. A tablet on Binary 9 requires Binary 9 or higher. - Confirm the Build Date: The last four characters of the PDA version indicate the build date. The first letter is the year (A=2024, B=2025, C=2026), and the second is the month (A=Jan through L=Dec).
- Verify in Download Mode: Turn the tablet off and hold Volume Down + Power to open Download Mode. This screen displays your exact model, CSC, and software version for easy verification.

Which Firmware Version Should I Download?
You should download the firmware version that directly matches your specific issue and current binary level. I receive this question frequently, so I created this reference table. Find your scenario and grab the correct file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | XU1ATH1, download this one. It is the latest Samsung Galaxy Tab S7 SM-T870 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 XU1ATH1 first, then follow the IMEI repair guide. Do not skip the reflash. |
| XU1ATH1 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 | XU1ATH1, 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 S7 SM-T870 Firmware
You can download the official Samsung Galaxy Tab S7 SM-T870 firmware directly from the links provided below. The newest available release is XU1ATH1. Once the download finishes, compare the file size against the specifications listed earlier. A mismatched file size usually indicates a corrupted download, which will cause errors during the flashing process.

Always ensure the file matches your exact tablet model. See the firmware selection guide above if you are not sure.
- Your model number is a variant of SM-T870 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 865 Plus. 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 S7 SM-T870 Firmware
Preparing your computer and tablet properly ensures the Samsung Galaxy Tab S7 SM-T870 firmware installation goes smoothly. Two issues frequently trip people up. First, leaving a Samsung account signed in will trigger KG lock. Second, using a cheap charging cable instead of a true data cable will drop the connection mid-flash. Check these requirements before starting:
- Back Up IMEI Numbers: Dial *#06# and write down your IMEI numbers. Keep them safe in case you need to restore your baseband later.
- Remove Google Accounts: Sign out of every Google account to prevent an FRP lock.
- Remove Samsung Accounts: Sign out of Samsung accounts to bypass KG lock.
- Back Up Your Data: Save your photos, contacts, and files. The flash will wipe the internal storage completely.
- Charge Your Device: Ensure the battery is at least 50%. A shutdown during a flash is difficult to recover from.
- USB Cable & PC: Connect using a high-quality data USB cable and a Windows computer.
- Install Required Drivers:

What to Expect After Flashing Samsung Galaxy Tab S7 SM-T870 Firmware
After flashing the Samsung Galaxy Tab S7 SM-T870 firmware, your tablet will take several minutes to boot up and optimize its apps. Many people assume something went wrong during the first boot, but the behaviors listed below are completely normal:
- How to know the flash was successful: A green “PASS.” message in Odin confirms a successful installation.
- First boot takes 3 to 8 minutes: Let the tablet sit. The system is configuring itself, and interrupting it can cause a bootloop.
- The phone will feel warm during first boot: This is standard behavior while the processor handles the initial setup load.
- All your apps are gone: The internal storage was wiped. Reinstall your apps via the Play Store or restore them from a Google backup.
- Dial *#06# immediately after setup: Check your IMEI before inserting a SIM card. If it reads “unknown”, check the IMEI repair guide.
- Be careful when re-adding your Google account: Add the account during the initial setup wizard to avoid FRP prompts.
- Wi-Fi, Bluetooth, and mobile data: These should function normally. If mobile data fails, manually input your APN settings in the network menu.
- Stuck in a bootloop after first boot? Boot into recovery and perform a factory reset. Check the hard reset guide above for instructions.
- Samsung Smart Switch: Smart Switch might download extra security updates after the flash. Allow it to finish installing them.
Missing IMEI or Corrupt Baseband on Samsung Galaxy Tab S7 SM-T870 After Flashing?
A missing IMEI or corrupt baseband on the Samsung Galaxy Tab S7 SM-T870 usually means the EFS partition was wiped during the flash. The EFS partition holds your IMEI and network data. Restoring an IMEI that does not belong to your original device is illegal in many regions, so only restore your own numbers. Software like ChimeraTool or BFT can repair this issue. Verify your local regulations before proceeding.

- Open recovery mode and run a factory reset to clear conflicting data left behind by the old operating system.
Frequently Asked Questions
Q1: Will flashing the Samsung Galaxy Tab S7 SM-T870 firmware erase my data?
A: Yes, installing this firmware through Odin completely wipes the tablet and installs a fresh copy of Android 10, upgradable to Android 13, One UI 5.1.
