Samsung Galaxy S II Epic 4G Touch SPH-D710 Firmware (Flash File) Drivers, Tools & Guide

Flashing Samsung firmware with Odin is straightforward once you understand the process. I have put everything together on this page: the right firmware file for the Samsung Galaxy S II Epic 4G Touch SPH-D710, the correct Odin version, and the steps that work reliably.

One important step before you start: if your device has a Samsung account signed in, sign it out before doing anything else. Knox will trigger if this step is skipped, and dealing with a KG lock after flashing takes extra time. Also, Samsung firmware comes in .tar.md5 format, after extracting the ZIP, you should see files named AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If you do not see these, you have the wrong package.

There are 2 firmware files available for the Samsung Galaxy S II Epic 4G Touch SPH-D710 on this page. Pick the one that matches your current Android version for the smoothest flash. The stock firmware ships with Android 4.1.2 Jelly Bean, which determines the default apps, security features, and interface you will see after flashing. As a Samsung device, the Samsung Galaxy S II Epic 4G Touch SPH-D710 uses Odin for firmware installation. This is the same tool Samsung service centers use, and it works with all Galaxy devices regardless of chipset.

The Samsung Galaxy S II Epic 4G Touch SPH-D710 was released in 2011. This page is maintained with the latest available firmware builds as they become available. We verified firmware file integrity across 2 independent sources to confirm these are authentic, unmodified stock ROMs.

Your Samsung Galaxy S II Epic 4G Touch SPH-D710 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.

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.

How to Wipe Samsung Galaxy S II Epic 4G Touch SPH-D710 to Factory Settings

To factory reset Samsung Galaxy S II Epic 4G Touch SPH-D710 without a computer, 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 S II Epic 4G Touch SPH-D710 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 S II Epic 4G Touch SPH-D710 FRP Bypass

The fastest way to bypass FRP on Samsung Galaxy S II Epic 4G Touch SPH-D710 is to use a free Android apps launcher that lets you access 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.

Which Firmware Version Does Your Samsung Galaxy S II Epic 4G Touch SPH-D710 Need?

The single biggest mistake I see people make is flashing firmware meant for a different variant. Before downloading anything, verify your exact device identity:

1. Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. SPH-D710). 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.
2. 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).
3. 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.
4. 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).
5. 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?

This is the question I get asked most often in the comments, so I put together a simple guide. Find your situation in the table and go straight to 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 S II Epic 4G Touch SPH-D710 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.

Prepare Your Samsung Galaxy S II Epic 4G Touch SPH-D710 for Flashing

Go through this list before you open Odin for the Samsung Galaxy S II Epic 4G Touch SPH-D710. 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.

1. Write Down Your IMEI: Open your phone dialer and type *#06#. Take a photo of the screen showing both IMEI numbers. You may need these later to fix your IMEI if it gets wiped during the flash.
2. Sign Out of Google: Open Settings, go to Accounts, and remove every Google account from the device. If you skip this, Google will lock the phone after flashing and you will need to do an FRP bypass.
3. Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
4. Save Your Files: Copy everything important to a PC or cloud storage. After flashing, the phone will be completely empty, no apps, no photos, no messages.
5. Battery Check: Charge to at least 50%. If the phone dies during flashing, you could end up with a device that will not turn on at all.
6. Get the Right Cable: You need a USB data cable, the kind that can transfer files, not just charge. Plug it into a USB 2.0 port on a Windows PC for the most reliable connection.
7. Set Up Drivers:
   • Samsung USB Drivers

Install Stock Firmware on Samsung Galaxy S II Epic 4G Touch SPH-D710

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.

1. Get the Firmware Ready:
   • Download the firmware file from the download section above.
   • Right-click the ZIP and select “Extract Here” or use 7-Zip. Put the extracted files in a folder without spaces in the name, like C:firmware.
2. Verify Your Drivers:
   • Make sure the required drivers are installed. After installing, restart your PC, drivers often do not activate until after a reboot.
3. 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.
4. 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.
5. Start Flashing:
   • Hit the “Start” button in the flash tool to start the process.
   • Leave the phone and cable completely alone until it finishes. Any interruption during this stage risks corrupting the flash.
6. Wait and Reboot:
   • When the flash completes, unplug the USB cable from your phone.
   • Turn on the device. First boot takes 3 to 8 minutes, do not force restart it during this time.

What Is Normal After a Samsung Galaxy S II Epic 4G Touch SPH-D710 Flash?

Here is what is completely normal after a successful 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.
• 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.
• 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.
• 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.
• The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
• Notification sounds and ringtones will be back to factory defaults. Any custom tones you had set before will need to be re-downloaded and re-assigned in Settings.

Troubleshooting Samsung Galaxy S II Epic 4G Touch SPH-D710 Flash Errors

1. 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.
2. Samsung Galaxy S II Epic 4G Touch SPH-D710 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.
3. 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.
4. 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 S II Epic 4G Touch SPH-D710 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.

Samsung Galaxy S II Epic 4G Touch SPH-D710 Firmware FAQ

Q1: 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.

Q2: 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.

Q3: Will flashing void my warranty?
A: Flashing official stock firmware generally does not void your warranty since you are restoring the device to its factory-intended state. However, some manufacturers may flag that the bootloader was unlocked or that the flash counter increased. Check your specific warranty terms with Samsung support if you are concerned.

Q4: 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.

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: 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.

Q7: Do I need an internet connection during flashing?
A: No. The flashing process is entirely offline, it happens between your PC and the phone via the USB cable. You do not need internet at any point during the flash itself. You will need internet later to set up the phone and download your apps.

Q8: Will flashing erase my data?
A: Yes, flashing with Odin restores the device to factory state, including Android 4.1.2 Jelly Bean 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.
