Samsung Dart T499 SGH-T499 Firmware (Flash File) Drivers, Tools & Guide
This page contains the official Samsung Dart T499 SGH-T499 firmware and instructions to restore your phone to factory settings. You will find the necessary drivers, the correct flash tool, and a step-by-step guide here.
Flashing Samsung firmware with Odin is straightforward if you follow the correct steps. I have compiled the right firmware file for the Samsung Dart T499 SGH-T499, the correct Odin version, and the steps that work on this page.
One step you should do before starting is to sign out of your Samsung account if it is still logged in. Knox will trigger if you skip this, and dealing with a KG lock after flashing takes extra time. 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.
The Samsung Dart T499 SGH-T499 was originally released in 2011, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play. Powered by a Qualcomm MSM7227-1 (Qualcomm) processor, the Samsung Dart T499 SGH-T499 requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Make sure to install the correct driver package before connecting your device. The stock firmware ships with Android 2.2 (Froyo) with TouchWiz UI, which determines the default apps, security features, and interface you will see after flashing.
This firmware was sourced directly from verified repositories and checked for integrity before being listed on this page. The Samsung Dart T499 SGH-T499 was released in 2011. This page is maintained with the latest available firmware builds as they become available.
Your Samsung Dart T499 SGH-T499 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.
Bypass Google Lock on Samsung Dart T499 SGH-T499
The fastest way to bypass FRP on Samsung Dart T499 SGH-T499 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.
Factory Reset Samsung Dart T499 SGH-T499 Without a PC
To factory reset Samsung Dart T499 SGH-T499 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 Dart T499 SGH-T499 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 Dart T499 SGH-T499 Firmware Compatibility Check
The single biggest mistake I see people make is flashing firmware meant for a different 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. SGH-T499). 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?
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 Dart T499 SGH-T499 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.

What You Need Before Flashing Samsung Dart T499 SGH-T499
Go through this list before you open Odin for the Samsung Dart T499 SGH-T499. 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.
- 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.
- 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.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- 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.
- 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.
- 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.
- Set Up Drivers:
Step-by-Step: Flash Samsung Dart T499 SGH-T499 Stock ROM
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.
- 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.
- Verify Your Drivers:
- Make sure the required drivers are installed. After installing, restart your PC, drivers often do not activate until after a reboot.
- 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:
- 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.
- 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.

Common Issues When Flashing Samsung Dart T499 SGH-T499
- 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 Dart T499 SGH-T499 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.
Normal Behavior After Installing Samsung Dart T499 SGH-T499 Firmware
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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- 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.
- 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.
- Fingerprint and face unlock data are erased during the flash. You will need to re-register your fingerprints and face data from scratch in the security 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.
Missing IMEI or Corrupt Baseband on Samsung Dart T499 SGH-T499 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.

Questions About Samsung Dart T499 SGH-T499 Firmware
Q1: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q2: Can I go back to an older firmware version?
A: It is technically possible on some Qualcomm 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.
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: 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.
Q6: Will flashing erase my data?
A: Yes, flashing with Odin restores the device to factory state, including Android 2.2 (Froyo) with TouchWiz 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.
Q7: 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.
Q8: 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.
