Samsung Galaxy Y Pro B5510 GT-B5510 Firmware (Flash File) Drivers, Tools & Guide
Flashing Samsung firmware with Odin is straightforward if you follow the correct steps. I have gathered everything you need here: the correct firmware file for the Samsung Galaxy Y Pro B5510 GT-B5510, the proper Odin version, and the steps to make it work.
Before you start, ensure you sign out of any Samsung accounts on the device. If you skip this, Knox will trigger, and dealing with a KG lock afterward 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 Galaxy Y Pro B5510 GT-B5510 uses Odin for firmware installation, just like other Samsung devices. The stock firmware ships with Android 2.3.6 (Gingerbread), which sets the default apps and security features you will see after flashing. Only one firmware build is currently available for the Samsung Galaxy Y Pro B5510 GT-B5510. This is the stock ROM you should use for recovery, unbricking, or FRP bypass.
Samsung firmware uses a multi-file system (AP, BL, CP, CSC) specific to Odin-based flashing. This differs from single-file scatter-based tools. This firmware was sourced from verified repositories and checked for integrity before being listed on this page.
Your Samsung Galaxy Y Pro B5510 GT-B5510 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.
Flashing replaces your current software completely and wipes all personal data. This is by design, it is what clears out FRP locks, bootloops, pattern locks, app crashes, and other software-level problems that a regular reset cannot fix.
Factory Reset Samsung Galaxy Y Pro B5510 GT-B5510 Without a PC
To factory reset the Samsung Galaxy Y Pro B5510 GT-B5510 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 the Samsung Galaxy Y Pro B5510 GT-B5510 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 Y Pro B5510 GT-B5510 FRP Bypass
The fastest way to bypass FRP on the Samsung Galaxy Y Pro B5510 GT-B5510 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.
Why Flash Stock ROM on Samsung Galaxy Y Pro B5510 GT-B5510?
Samsung devices like the Samsung Galaxy Y Pro B5510 GT-B5510 are flashed using Odin, regardless of the chipset inside. Whether you are dealing with a boot issue or a software problem, flashing the official firmware can resolve it:
- Update to the latest Android version supported by your phone.
- Recover your device when it only boots into recovery mode.
- Resolve touchscreen responsiveness issues caused by a corrupted system build.
- Fix startup loops, lagging, and freezing on your device.

Choosing the Right Firmware Version
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. GT-B5510). 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 Y Pro B5510 GT-B5510 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 Y Pro B5510 GT-B5510 for Flashing
Go through this list before you open Odin for the Samsung Galaxy Y Pro B5510 GT-B5510. 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.
- IMEI Backup: Open the dialer and enter *#06#. Write both IMEI numbers down on paper or take a screenshot. If you ever need to repair your IMEI after flashing, these are essential.
- Remove All Google Accounts: Go to Settings, Accounts, and sign out of every Google account on the device. Leaving accounts signed in triggers FRP lock after a flash, which blocks you from setting up the phone.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Backup Everything: Photos, contacts, messages, WhatsApp data, move it all to a computer or cloud service. The flash will restore the phone to factory state with nothing on it.
- 50% Battery Minimum: Do not start with a low battery. If power cuts out during the flash, the device can become unresponsive and much harder to fix.
- USB Cable and Computer: Use a proper data-transfer USB cable and a Windows PC. Avoid USB hubs, connect directly to the motherboard port for a stable connection.
- Download and Install Drivers:
Samsung Galaxy Y Pro B5510 GT-B5510 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 Unpack:
- Pick the correct firmware version from the downloads above and save it to your PC.
- Extract the ZIP file. If the extracted folder contains another ZIP inside, extract that one too. You should end up with the actual firmware files, not another archive.
- Driver Check:
- Double-check that you have installed the required drivers. A missing driver is the most common reason the flash tool cannot detect your phone. Reboot your PC after installing.
- 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:
- Start the flash by clicking “Start”.
- Leave everything untouched until completion. Even bumping the USB cable can interrupt the write and cause a failed flash.
- Wait and Reboot:
- The flash is complete when the tool shows a success indicator. Disconnect your phone.
- Turn the phone on. Do not worry if it sits on the boot logo for several minutes, the system is rebuilding itself from scratch.

After Flashing: What Happens Next on Samsung Galaxy Y Pro B5510 GT-B5510
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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
What to Do if Samsung Galaxy Y Pro B5510 GT-B5510 Flash Fails
- 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 Y Pro B5510 GT-B5510 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 Y Pro B5510 GT-B5510 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 Galaxy Y Pro B5510 GT-B5510 Firmware
Q1: 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.
Q2: 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.
Q3: 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.
Q4: 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.
Q5: Will flashing erase my data?
A: Yes, flashing with Odin restores the device to factory state, including Android 2.3.6 (Gingerbread) 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.
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: Can I go back to an older firmware version?
A: It is technically possible on some MediaTek 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.
Q8: Is this firmware compatible with other Samsung models?
A: No. This firmware is built specifically for the Samsung Galaxy Y Pro B5510 GT-B5510 running on the Broadcom BCM21553 chipset. Even variants of the Galaxy Y Pro B5510 with a different letter suffix can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings.
