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.

Choosing the Right Firmware Version
Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. C7108). 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?
Your Situation
What I Recommend
Phone is completely dead or stuck on logo
MU1ARG1, download this one. It is the latest Samsung Galaxy C7 C7108 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.
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 C7 C7108 Firmware
MU1ARG1. 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.
See the firmware selection guide above if you are not sure.
⚠ Compatibility Warning, Do NOT flash this firmware if:
Your model number is a variant of C7108 with a different letter suffix. Check About Phone carefully, one letter difference can cause a failed or broken flash.
Your chipset differs from MediaTek Helio P25 (MT6757T). 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.
Prerequisites for Samsung Galaxy C7 C7108 Firmware
Back Up IMEI Numbers: Dial *#06# and write down both IMEI numbers now. You will need these if you need to restore your IMEI after flashing.
Remove Google Accounts: Sign out of all Google accounts to prevent FRP lock after flashing.
Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
Back Up Your Data: Back up everything, photos, contacts, WhatsApp chats, important files. Flashing wipes the device completely.
Charge Your Device: At least 50% battery. A device that powers off during a flash is very difficult to recover.
USB Cable & PC: Use a proper data USB cable, not a charge-only cable, and a Windows computer with available USB ports.
How to Install Firmware on Samsung Galaxy C7 C7108
our Odin versions page. Some older Samsung devices work better with older Odin builds.
Download and Extract:
Download the correct firmware package from the links above.
Extract the ZIP to a simple folder path, avoid paths with spaces or special characters, as some flash tools have trouble with them.
Install the Listed Drivers:
Confirm all drivers listed above are installed and that your PC has been restarted since installation. Skipping the restart is a common reason drivers do not work correctly.
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 the “Start” button to begin.
Do not disconnect, move the cable, or touch the device until the process is fully complete. Disconnecting mid-flash is how devices get bricked.
Wait and Reboot:
Once flashing finishes successfully, disconnect the device.
Power on your device. The first boot will take longer than usual, give it up to 8 minutes.
Video Guide for Flashing
What to Expect After Flashing Samsung Galaxy C7 C7108 Firmware
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.
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.
The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
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.
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.
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.
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, it is usually a conflict with leftover data from the old install.
Samsung Smart Switch: After flashing your Samsung Galaxy C7 C7108 firmware, Samsung Smart Switch may prompt you to install additional updates. Let it complete, this ensures your device has the latest security patches for your region.
