Samsung Galaxy Tab S 8.4 LTE SM-T705 Firmware (Flash File) Drivers, Tools & Guide
Flashing firmware on Samsung devices with Odin is generally straightforward once you understand the necessary steps and preparations. This guide compiles all components required for the Samsung Galaxy Tab S 8.4 LTE SM-T705: the correct firmware package, the appropriate Odin version, and a reliable flashing procedure.
Before you begin the flashing process, an important step is to remove any Samsung accounts linked to your device. Failing to sign out can activate Knox, leading to a KG lock that requires additional time to address after the flash. Regarding firmware files, official Samsung packages come in .tar.md5 format; after extracting the downloaded ZIP file, you should find individual files designated as AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If these specific files are not present, it indicates that you might have an incorrect firmware package.
The Samsung Galaxy Tab S 8.4 LTE SM-T705 firmware is provided as a compressed ZIP file. You will need to download and extract it using an archiving tool like WinRAR or 7-Zip. Once extracted, you should see files such as AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If these specific files are not visible, it suggests that the firmware package might be incorrect for your device.
Remember that flashing stock firmware will erase all existing data on your device. This is by design, as a complete reset helps resolve various software-related issues, including FRP locks, application malfunctions, sluggish performance, forgotten screen locks, devices stuck on the logo or failing to boot, Wi-Fi and Bluetooth connectivity problems, excessive battery drain, and soft brick situations.
Hard Reset Samsung Galaxy Tab S 8.4 LTE SM-T705
To factory reset your Samsung Galaxy Tab S 8.4 LTE SM-T705 without a computer, ensure the device is fully powered off, then simultaneously press and hold the Volume Up + Power buttons until the recovery menu appears. For older models that include a physical Home button, the combination is Volume Up + Home + Power. Navigate through the menu using the volume keys to highlight “Wipe Data/Factory Reset” and confirm your selection with the Power button.
Performing a hard reset clears all data and restores the Samsung Galaxy Tab S 8.4 LTE SM-T705 to its original factory settings. This action can resolve most software problems, such as slow operation, app crashes, forgotten screen patterns, and boot loops. If the problem continues after a factory reset, a complete firmware flash using Odin, as detailed in the subsequent sections, is the next step.
Samsung Galaxy Tab S 8.4 LTE SM-T705 FRP Bypass
The most efficient method to bypass FRP on the Samsung Galaxy Tab S 8.4 LTE SM-T705 involves using a free Android apps launcher that grants access to system settings during the initial setup wizard. After a flash or factory reset, your device may display a Google account lock, also known as FRP. Our free Android apps launcher offers the quickest way to proceed past this screen. This is also why I always advise removing your Google account before flashing, as it prevents this issue entirely.
Why Do We Need Samsung Galaxy Tab S 8.4 LTE SM-T705 Firmware?
Samsung devices, including the Samsung Galaxy Tab S 8.4 LTE SM-T705, are flashed using Odin, regardless of their internal chipset. Whether you are addressing a boot issue or another software problem, flashing the official firmware can resolve it through several benefits:
- It can unlock your device if it has become locked or disabled.
- It allows for updates to the most recent Android version supported by your phone.

Discover more details about stock ROMs and the effectiveness of flashing.
Choosing the Right Firmware Version
Before you start the flashing process, it is important to confirm that you have selected the correct firmware file. Using an incompatible firmware is a mistake that can be difficult to correct:
- Identify Your Exact Model Number: Navigate to Settings › About Phone and precisely note your full model number (for example, SM-T705). The letter suffix is important, U/U1 typically indicates USA, W for Canada, N for Korea, and B/F for International/Global variants. Flashing firmware intended for a different variant can lead to operational issues.
- Match the CSC (Region): The three-letter region code found in the firmware filename needs to match your device’s region. You can check Settings › About Phone › Software Information for your current CSC, or view the Service Provider line when the device is in Download Mode. Common codes include XAA (US), BTU (UK), INS (India), and SER (Russia).
- Check the Binary Level: Examine the version string in your device’s current firmware (for example,
XXU9BZDP, the numerical digit after the letters represents the binary level). You are unable to downgrade to a lower binary level. If your device is currently on Binary 9, you should only flash firmware with Binary 9 or a higher version. - Confirm the Build Date: The final four characters of the PDA version string encode the build date, the first character indicates the year (A=2024, B=2025, C=2026), and the second indicates the month (A=Jan through L=Dec).
- Verify in Download Mode: Power off your device, then hold Volume Down + Power simultaneously to enter Download Mode. This screen displays your exact model, CSC, and current firmware version, which you should use for confirmation before proceeding with any flashing.

Which Firmware Version Should I Download?
This is a common inquiry, so I have compiled a straightforward guide to help you choose. Locate your specific situation in the table below to quickly find the appropriate file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | T705DDS1CRK1, this is the latest Samsung Galaxy Tab S 8.4 LTE SM-T705 firmware currently available. |
| FRP / Google account lock only | Refer to the FRP bypass guide mentioned above, a full firmware flash is likely not necessary for this issue. |
| Not sure which region/CSC to download | Check your current CSC under Settings › About Phone › Software Information, or enter Download Mode (Volume Down + Power) where it is displayed on screen. Match the three-letter code (for example, XAA, BTU, INS) to the firmware filename. |
| Phone slow after a recent OTA update | Consider trying XU1BOJ8, sometimes the newest OTA updates can introduce performance issues, and an earlier build might run more smoothly. Always ensure the binary level is the same or higher than what your device currently has. |
| IMEI missing after a previous flash | First, re-flash T705DDS1CRK1, then proceed with the IMEI repair guide. Do not skip the reflash step. |
| T705DDS1CRK1 failed with a flash error | Attempt to flash XU1BOJ8 instead, and carefully re-verify your AP/BL/CP/CSC file assignments in Odin before concluding the firmware itself is the cause of the problem. |
| Restoring to factory / warranty repair | T705DDS1CRK1, for a clean slate and a fresh start. |
To determine which Samsung firmware is newer, examine the last four characters of the PDA version string (for example, S938BXXU9CZDP). The first character denotes the year (A=2024, B=2025, C=2026), the second indicates the month (A=Jan, B=Feb… L=Dec, Z=final stable), and the final two characters represent the revision (0-9 then A-Z, where Z signifies the highest). However, before comparing dates, always verify the binary level: this is the digit immediately preceding the date code (for example, XXU9CZDP = Binary 9). You are unable to downgrade to a lower binary level. If your device is on Binary 9, you should only flash Binary 9 or higher firmware. Also, ensure the three-letter CSC code within the firmware matches your device’s regional code.

What to Expect After Flashing Samsung Galaxy Tab S 8.4 LTE SM-T705 Firmware
Many individuals express concern when their device behaves differently right after a flash, even when everything is proceeding normally. Here is what is entirely typical after a successful Samsung Galaxy Tab S 8.4 LTE SM-T705 firmware installation:
- How to know the flash was successful: Odin will display “PASS.” in green text in the top-left area of its log. If you see this message, the process completed without issues.
- The first boot cycle will take three to eight minutes, do not attempt to force a reboot. The operating system is configuring itself from scratch. Interrupting this stage can cause the device to enter a bootloop.
- The phone may feel warm during the first boot, this is a normal occurrence. The temperature will stabilize after a few minutes once the initial application setup processes are finished.
- All your applications will be removed, this outcome is expected. You will need to reinstall them from the Play Store. If you had an active Google account backup, the setup process will offer to restore your applications automatically.
- Dial *#06# immediately following setup to confirm your IMEI. Perform this check before inserting a SIM card. If it displays “unknown” or “null,” follow the IMEI repair guide below before proceeding with anything else.
- Exercise caution when re-adding your Google account, if you neglected to remove it prior to flashing, you might encounter an FRP prompt. Add the account afresh during the initial setup wizard, rather than later through the Settings menu.
- Wi-Fi, Bluetooth, and mobile data should all function correctly immediately after setup. If mobile data is not connecting, go to Settings › SIM and Network and manually re-enter your APN details, as the flash can sometimes clear carrier APN settings.
- Stuck in a bootloop after the initial boot? Enter recovery mode and perform a factory reset from there; refer to the hard reset guide above. This can happen occasionally and does not necessarily mean the firmware is incorrect; it is usually due to a conflict with residual data from the previous installation.
- Samsung Smart Switch: After successfully flashing your Samsung Galaxy Tab S 8.4 LTE SM-T705 firmware, Samsung Smart Switch may prompt you to install additional updates. Allow these to complete, as this ensures your device receives the most recent security patches for your region.
Missing IMEI or Corrupt Baseband on Samsung Galaxy Tab S 8.4 LTE SM-T705 After Flashing?
A missing IMEI on a Samsung device after flashing typically indicates a corrupted EFS partition. This partition is responsible for storing your IMEI and carrier configuration. Please be aware that restoring an IMEI number that is not original to your device is unlawful in most jurisdictions; therefore, only proceed if you are restoring the number the device possessed before you initiated the flash. Specialized tools such as ChimeraTool or BFT can assist with this process. Always check your local laws before taking any action.
