Samsung Galaxy W I8150 Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is a straightforward process once you understand the steps. I have gathered the correct firmware file for the Samsung Galaxy W I8150, the proper Odin version, and the necessary steps here.
One thing to do 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.
Powered by a Qualcomm MSM8255T Snapdragon S2 processor, the Samsung Galaxy W I8150 requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Make sure to install the correct driver package before connecting your device. Only one firmware build is currently available for the Samsung Galaxy W I8150. This is the stock ROM you should use for recovery, unbricking, or FRP bypass. The Samsung Galaxy W I8150 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.
This firmware was sourced directly from verified repositories and checked for integrity before being listed on this page. 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 W I8150 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.
Once you flash, the device goes back to factory condition. Everything stored on the phone, photos, messages, apps, will be gone. This clean state is what allows the flash to fix stuck logos, FRP locks, software corruption, and performance issues.
FRP Removal for Samsung Galaxy W I8150
The fastest way to bypass FRP on Samsung Galaxy W I8150 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.
How to Wipe Samsung Galaxy W I8150 to Factory Settings
To factory reset Samsung Galaxy W I8150 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 W I8150 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 W I8150 Firmware Compatibility Check
The single biggest mistake 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. I8150). 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 Galaxy W I8150 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.
Download Samsung Galaxy W I8150 Firmware
Download the official stock firmware for your Samsung Galaxy W I8150 below. The latest available version is the latest version. After downloading, verify the file size matches the table above, a size mismatch usually means a partial or corrupt download, and flashing a corrupt file can cause more problems than it solves.
| Software Details | Download Link | Members Link |
|---|---|---|
|
File Name: I8150XXLMJ_I8150OXXLC2_BGL_2.3.6.zip Size: 329.8 MB | Download Link | Download Link2 |
Only download firmware that is fully compatible with your exact device model. See the firmware selection guide above if you are not sure.
Important: The Samsung Galaxy W I8150 (I8150) should not be confused with other Galaxy W I8150 variants that may have different chipsets or regional firmware. Even devices in the same Galaxy W I8150 line can use completely different processors. Always verify your exact model code “I8150” in Settings > About Phone before downloading any firmware from this page.
- Your model number is a variant of I8150 with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
- Your chipset differs from Qualcomm MSM8255T Snapdragon S2. 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.
Prepare Your Samsung Galaxy W I8150 for Flashing
Go through this list before you open Odin for the Samsung Galaxy W I8150. 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 anything, 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:
How to Install Firmware on Samsung Galaxy W I8150
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.
- Prepare the Flash Files:
- Go to the download section and grab the firmware package that matches your device.
- Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
- Confirm Driver Setup:
- The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
- 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 “Start” to kick off the firmware write.
- Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When you see the success message, disconnect the USB cable.
- Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.

Troubleshooting Samsung Galaxy W I8150 Flash Errors
- 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 W I8150 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.
What to Expect After Flashing
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.
- 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.
- 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
- 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.
Missing IMEI or Corrupt Baseband on Samsung Galaxy W I8150 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.

Common Questions About Flashing Samsung Galaxy W I8150
Q1: 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.
Q2: What if the flash fails halfway through?
A: Do not panic and do not disconnect the phone. Close Odin, restart it, and try the flash again from the beginning. In most cases, a failed flash just means the process needs to be repeated. The device is usually still detectable by the flash tool even after a failed attempt.
Q3: 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.
Q4: 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.
Q5: 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.
Q6: 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.
Q7: 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.
Q8: 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.
