Samsung Galaxy Tab 4 7.0 LTE SM-T235Y Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a standard procedure once you understand the steps. This page provides the specific files for the Samsung Galaxy Tab 4 7.0 LTE SM-T235Y, the correct Odin version, and the necessary steps.
Before you begin, sign out of your Samsung account if it is logged in. Skipping this step often triggers a Knox guard (KG) lock, which complicates the process later. Also, ensure you have extracted the firmware correctly; the package must contain AP, BL, CP, and CSC files.
The Samsung Galaxy Tab 4 7.0 LTE SM-T235Y firmware is available in a multi-file format. This specific device runs on the Samsung Exynos 3 Quad 3470 chipset and uses Odin for installation. The stock firmware ships with Android 4.4.2 (KitKat) and TouchWiz UX UI. This determines the default apps, security features, and interface you will see after flashing. Only one firmware build is currently available for the Samsung Galaxy Tab 4 7.0 LTE SM-T235Y. Use this stock ROM for recovery, unbricking, or FRP bypass.
The Samsung Galaxy Tab 4 7.0 LTE SM-T235Y was released in 2014. This page is maintained with the latest available firmware builds as they become available. Samsung firmware uses a multi-file system (AP, BL, CP, CSC) specific to Odin-based flashing, which differs from single-file scatter-based tools.
Your Samsung Galaxy Tab 4 7.0 LTE SM-T235Y firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. After extracting, 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 you do not see these files, you may have the wrong firmware package for your device.
Be aware that flashing overwrites the entire software partition. Your data, apps, and accounts will all be removed. This full wipe is how the flash resolves deep software issues, anything from FRP locks and boot failures to Wi-Fi problems and app crashes.
How to Wipe Samsung Galaxy Tab 4 7.0 LTE SM-T235Y to Factory Settings
Factory resetting the Samsung Galaxy Tab 4 7.0 LTE SM-T235Y clears all data and restores the system to its default state. Power off the device completely, then hold Volume Up + Power (for older models with a Home button, use Volume Up + Home + 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 4 7.0 LTE SM-T235Y 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 4 7.0 LTE SM-T235Y Google Account Bypass After Reset
The most common way to bypass the Google account lock on the Samsung Galaxy Tab 4 7.0 LTE SM-T235Y involves using a third-party app 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 is the fastest way to get past it. This is also why I always recommend removing your Google account before flashing, it avoids this problem entirely.
Common Reasons to Reinstall Samsung Galaxy Tab 4 7.0 LTE SM-T235Y Firmware

How to Pick the Correct Samsung Galaxy Tab 4 7.0 LTE SM-T235Y Firmware
The most frequent error users make is installing firmware meant for a different regional variant. Before downloading anything, verify your exact device identity:
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. SM-T235Y). 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?
Choosing the right file for your specific situation is crucial for a successful flash. Refer to the table below to identify the correct version:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | ZTS1AQA1, download this one. It is the latest Samsung Galaxy Tab 4 7.0 LTE SM-T235Y 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 ZTS1AQA1 first, then follow the IMEI repair guide. Do not skip the reflash. |
| ZTS1AQA1 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 | ZTS1AQA1, 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.

Important: The Samsung Galaxy Tab 4 7.0 LTE SM-T235Y (SM-T235Y) should not be confused with other Galaxy Tab 4 7.0 LTE variants that may have different chipsets or regional firmware. Even devices in the same Galaxy Tab 4 7.0 LTE line can use completely different processors. Always verify your exact model code “SM-T235Y” in Settings > About Phone before downloading any firmware from this page.
- Confirm your exact model is SM-T235Y, check About Phone, not the marketing name on the box.
- Your device must have a Samsung Exynos 3 Quad 3470 chipset. Boot into recovery mode to verify if unsure.
- Only use files downloaded from this page. Third-party mirrors may serve modified or incomplete packages.
- Compare the file size against the download table. If it does not match, the download is likely corrupt or incomplete.
Prepare Your Samsung Galaxy Tab 4 7.0 LTE SM-T235Y for Flashing
Proper preparation prevents most errors when flashing the Samsung Galaxy Tab 4 7.0 LTE SM-T235Y. Two things that commonly cause problems with Samsung devices: 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.
- Save Your IMEI Numbers: Type *#06# in the phone dialer and note down both numbers. These are your device identifiers for the cellular network. If flashing wipes them, you will need the originals to write them back.
- Disconnect Google Accounts: Before you start, remove all Google accounts from the phone. Settings then Accounts then tap each Google account and remove it. This avoids the FRP verification screen that appears after flashing if accounts were still linked.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Create a Backup: Copy your data to your computer or an SD card. Flashing replaces the entire software on the phone, which means all personal data, apps, and settings will be permanently deleted.
- Charge First: Get the battery above 50% before starting. The flashing process takes a few minutes and the first boot takes several more. A power failure during either stage can leave the device in a state that requires more advanced recovery.
- Prepare Your PC Connection: You need a Windows computer and a USB cable that supports data transfer. Test the cable first by connecting the phone normally, if it shows up in File Explorer, the cable is good.
- Install the Right Drivers:
Samsung Galaxy Tab 4 7.0 LTE SM-T235Y Firmware Installation Guide
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.
Video Guide for Flashing
What to Expect After Flashing
A successful flash results in a clean, factory-reset state. Here is what you should expect immediately after the process finishes:
- 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.
- The phone may ask for language and region again, this is normal after a flash. You are starting from a clean state, so the setup wizard runs just like when the phone was brand new.
- 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.
- Battery percentage may seem inaccurate for the first day. The battery statistics are calibrated during normal use. Charge the phone fully once without interruption and the readings will stabilize.
- Storage will show almost full capacity available since all your apps and files are gone. The system partition size varies by firmware version but is typically 4 to 8 GB on most devices.
- 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.
- 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.
Common Issues When Flashing Samsung Galaxy Tab 4 7.0 LTE SM-T235Y
- 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 4 7.0 LTE SM-T235Y 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.
Missing IMEI or Corrupt Baseband on Samsung Galaxy Tab 4 7.0 LTE SM-T235Y 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.

Frequently Asked Questions
Q1: My IMEI shows “unknown” after flashing. 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. Do not insert a SIM card until the IMEI is restored.
Q2: Can I use a Mac or Linux computer for this?
A: Samsung firmware can be flashed using Heimdall on Linux or Mac, but the instructions on this page are written for Odin on Windows. If you only have a Mac, you may want to use a Windows virtual machine or Boot Camp for the most straightforward experience.
Q3: Will flashing erase my data?
A: Yes, flashing with Odin restores the device to factory state, including Android 4.4.2 (KitKat), TouchWiz UX UI 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.
Q4: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock activates when a Google account was still signed in before flashing. This is why signing out of your Google account before flashing avoids this issue entirely.
Q5: Can I flash this firmware if my phone does not turn on at all?
A: Yes, in most cases. Samsung devices can usually enter Download Mode even when the screen is completely dead, hold Volume Down + Power for 10 seconds. If the battery is completely drained, charge it for at least 15 minutes first.
Q6: My device 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. Disable your antivirus temporarily. If none of that works, leave a comment with the exact error message.
Q7: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 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.
Q8: Can I go back to an older firmware version?
A: It is technically possible on some Exynos builds, but downgrading can cause security issues and app compatibility problems. If the latest version is causing trouble, leave a comment below, there is usually a better fix than rolling back.
