Samsung Galaxy Win I8550 I8552 Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is straightforward once you understand the file structure. This page contains the specific Samsung Galaxy Win I8550 I8552 firmware, the correct Odin version, and the steps that work reliably. Before starting, ensure your Samsung account is signed out to prevent Knox triggers. Also, verify that your extracted files match the expected naming convention (AP_*, BL_*, CP_*, CSC_*).
Released in 2013, the Samsung Galaxy Win I8550 I8552 runs on Android 4.1.2 (Jelly Bean). Due to its age, Windows 10 or 11 may require manual driver installation rather than plug-and-play. The stock firmware determines the default apps, security features, and interface you will see after the flash. Powered by a Qualcomm MSM8625Q Snapdragon 200 processor, the Samsung Galaxy Win I8550 I8552 requires Qualcomm Flash Image Loader (QFIL) and Qualcomm HS-USB drivers. Ensure you install the correct driver package before connecting your device.
Samsung firmware uses a multi-file system (AP, BL, CP, CSC) specific to Odin-based flashing, which differs from single-file scatter-based tools. The Samsung Galaxy Win I8550 I8552 was released in 2013. This page is updated with the latest available firmware builds as they become available.
Your Samsung Galaxy Win I8550 I8552 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.
Samsung Galaxy Win I8550 I8552 Google Account Bypass After Reset
The fastest way to bypass FRP on Samsung Galaxy Win I8550 I8552 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.
Hard Reset Samsung Galaxy Win I8550 I8552
To factory reset Samsung Galaxy Win I8550 I8552 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 Win I8550 I8552 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.
Which Firmware Version Does Your Samsung Galaxy Win I8550 I8552 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:
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. I8552). 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 Win I8550 I8552 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.

Important: The Samsung Galaxy Win I8550 I8552 (I8552) should not be confused with other Galaxy Win I8550 variants that may have different chipsets or regional firmware. Even devices in the same Galaxy Win I8550 line can use completely different processors. Always verify your exact model code “I8552” in Settings > About Phone before downloading any firmware from this page.
- Go to Settings and verify your model is exactly I8552. Phones with similar names can have completely different hardware.
- The chipset in your device should be Qualcomm MSM8625Q Snapdragon 200. If it is different, this firmware will not work.
- Always download directly from the table on this page to ensure you have the correct build.
- Check the file size after downloading, a mismatch with the listed size means a partial or corrupt download.
What You Need Before Flashing Samsung Galaxy Win I8550 I8552
Go through this list before you open Odin for the Samsung Galaxy Win I8550 I8552. 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.
- Record IMEI Before Flashing: Dial *#06# and save both IMEI numbers somewhere safe, a screenshot works. If flashing corrupts the baseband, these numbers are what you will need to restore cellular connectivity.
- Unlink Google Accounts: Go to Settings, then Accounts, and remove all Google accounts. This prevents Factory Reset Protection from activating after the flash. It is the single most skipped step and causes the most post-flash headaches.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Full Data Backup: Flashing erases everything. Transfer your photos, contacts, app data, and any important files to your computer or cloud backup before starting.
- Charge the Battery: Make sure you have at least 50% charge. A dead battery during a flash can corrupt the system partition and turn a fixable problem into a much bigger one.
- Windows PC and USB Cable: You will need a Windows computer and a data-capable USB cable. Cheap charge-only cables are the number one reason flash tools fail to detect devices.
- Driver Installation:
Install Stock Firmware on Samsung Galaxy Win I8550 I8552
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 the Firmware Package:
- Use the download links in the table above to get the correct firmware file for your device.
- Extract the archive with WinRAR or 7-Zip. Use a short folder path like
D:flashto avoid issues with some tools.
- Check Drivers:
- All drivers from the prerequisites must be installed before connecting your device. Restart your computer after installing them.
- 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:
- Press “Start” to begin writing the firmware to your device.
- Do not unplug the phone, close the flash tool, or interact with the device until the process is 100% complete.
- Wait and Reboot:
- After the tool confirms the flash is complete, safely disconnect your phone.
- Press the power button to start your device. The initial boot is slow, wait up to 8 minutes before assuming there is a problem.

Samsung Galaxy Win I8550 I8552 Flashing Problems and Fixes
- 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 Win I8550 I8552 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 Is Normal After a Samsung Galaxy Win I8550 I8552 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.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- 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.
- 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.
- 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.
- 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.
Missing IMEI or Corrupt Baseband on Samsung Galaxy Win I8550 I8552 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 Win I8550 I8552
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: How do I enter recovery mode?
A: Power the device off completely, then hold Volume Up + Power at the same time until the recovery menu appears. For older Samsung models with a physical Home button, use Volume Up + Home + Power. The recovery menu displays the build number which you can use to verify your firmware version before flashing.
Q3: 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.
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: 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.
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: 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.
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.
