Samsung Galaxy S6 Edge (G925A) Firmware Binary U7/U6 Android 7.0 Nougat Fix DRK/dm-verity Failed/OEM Lock On/FRP/Reactivation Lock
🔧 Samsung Galaxy S6 Edge (G925A) – DRK & dm-verity Fix Guide (Bit U6 / U7)
For the Samsung Galaxy S6 Edge (G925A), especially devices running on Binary Bit U6 or U7 firmware, issues like DRK Error and dm-verity failed can only be resolved by flashing the correct official stock firmware that matches the device’s binary level.
📱 If OEM Lock is ON and the phone is stuck on Reactivation Lock or FRP, you cannot install any custom kernel or recovery.
💻 First, download the correct G925A Bit U6/U7 official firmware and flash it using the Odin Tool to restore system files and remove the dm-verity error.
🧩 To bypass Reactivation Lock, the most effective method on Android 6.0.1 or Android 7.0 is the Combination File method.
⚙️ Flash the correct Bit U6/U7 Combination File first to access factory settings. From there, go to Developer Options and enable OEM Unlocking.
🔁 Once the security locks are disabled, flash the full stock firmware again. The phone should boot normally.
🛠️ If the DRK error still remains after flashing, you will need a professional repair tool such as Z3X or Octoplus Box.
✅ After a successful repair, the device will boot properly and reach the setup screen without DRK or dm-verity errors.

Samsung DRK (Device Root Key) fix
📱 On Samsung phones, the DRK (Device Root Key) error usually appears when the firmware becomes corrupted or a software update fails. This means the device’s security (root key) has mismatched.
🛠️ You can fix this issue by following the methods below:
✅ Method 1: Flash Stock Firmware (Best Solution)
The most reliable solution is to download the official Stock ROM for your exact phone model and flash it using the Odin tool.
- 🔍 Step 1: Check your phone’s model number (e.g., SM-G925F) from Recovery Mode.
- 🌍 Step 2: Download the latest firmware for your region using SamMobile or the Frija tool.
- ⬇️ Step 3: Boot the phone into Download Mode (Power + Volume Down + Home/Bixby).
- 💻 Step 4: Open Odin on your PC, load the 4 files (BL, AP, CP, CSC), and start flashing.
🔓 Method 2: Use CF-Auto-Root (For Old Models)
If your device is an older model (such as Galaxy S6 or S7), flashing the CF-Auto-Root file via Odin can fix the DRK error. This will root the phone but usually resolves bootloop issues.
🧩 Method 3: Fix DRK Files (Custom Kernels)
Some models have specific DRK Fix files available in TAR format.
- 🔎 Search online for:
[Your Model Number] DRK Fix File - 📂 Flash the file using the AP slot in Odin. These files bypass the device’s security verification.
⚙️ Method 4: Professional Tools (For Technicians)
If you have access to professional tools, the DRK issue can be fixed within seconds:
- 🧰 Z3X Box: Use the Repair DRK option.
- 🔧 Octoplus Box: Comes with a direct Fix DRK button.
- 💡 EFT Pro Dongle: Can fix both DM-Verity and DRK issues.
⚠️ Important Note: Flashing firmware may erase all data on your device. If you are not experienced with flashing, it is strongly recommended to consult a professional technician.
Samsung dm-verity verification failed fix
🚫 On Samsung phones, the "dm-verity verification failed" error usually appears when system files are modified or the software becomes corrupted. This error is commonly seen in Recovery Mode displayed in red text.
🛠️ Follow the steps below to fix this issue:
🔄 Method 1: Hard Reset (First & Easy Solution)
In some cases, simply wiping data can resolve the error.
- 📲 Boot your phone into Recovery Mode (Volume Up + Power + Home/Bixby).
- 🧹 Select Wipe Data / Factory Reset and confirm.
- 🗑️ After that, also select Wipe Cache Partition.
- 🔁 Restart the phone. Note: This will erase all user data.
💾 Method 2: Flash Official Stock Firmware (Most Reliable Fix)
If a reset does not work, reinstalling the official firmware is required.
- ⬇️ Download the Odin Tool and your device’s Official Firmware from SamMobile or Frija.
- ⚡ Put the phone into Download Mode.
- 📂 Load BL, AP, CP, and CSC files in Odin and start flashing.
- ✅ After installing fresh firmware, the dm-verity error is completely fixed.
🧩 Method 3: Flash “Fix DRK / dm-verity” File
If you don’t want to flash full firmware and your device is an older model, you can search online for a model-specific DRK Fix File (.tar format).
- 📁 Open Odin, load the file into the AP slot, and flash it. This file bypasses system verification checks.
⚙️ Method 4: Advanced Commands (Professionals Only)
If your bootloader is unlocked and you are using a PC, you may try ADB/Fastboot commands:
⌨️ fastboot oem enable_dm_verity
⌨️
fastboot oem disable_dm_verity
(Note: On most Samsung phones, Odin flashing is the effective
solution.)
⚠️ Advice: If you previously tried rooting your phone, this error is expected. The best and safest way to fix it is always flashing the official Stock ROM.
Samsung OEM Lock: ON fix
🔒 On Samsung phones, OEM Lock: ON means the bootloader is locked, and you cannot install any custom files such as TWRP, Root, or Custom ROMs. There are two possible situations to deal with this:
📱 Case 1: Phone Is ON (Fix from Settings)
If your phone is working normally and you want to unlock the bootloader:
- ⚙️ Go to Settings and tap on About Phone.
- 🧑💻 Open Software Information and tap Build Number 7 times until you see "Developer mode has been enabled".
- 🔙 Go back to Settings, scroll down, and open Developer Options.
- 🔓 Enable the OEM Unlocking toggle.
- ⏳ Note: If OEM Unlocking is not visible, connect the phone to Wi-Fi and wait 2–3 days, or try setting the date back by 7–10 days and check again.
⚠️ Case 2: Phone Stuck in Recovery / Download Mode
If you were flashing a file and got the error "Custom Binary Blocked by OEM Lock", it means the bootloader security has blocked an unofficial file.
- 💾 Flash Stock Firmware: The only solution is to re-flash the official original firmware (same Binary / Bit level) using the Odin tool.
- 🔐 Bootloader Unlock (New Models):
- 📴 Power off the phone.
- 🔌 Press and hold Volume Up + Volume Down, then connect the USB cable to the PC.
- ⬇️ The phone will enter the Download Mode warning screen.
- 📢 Long-press the Volume Up button.
- ✅ When "Unlock Bootloader?" appears, press Volume Up again to confirm. Warning: This will erase all data on the device.
🔑 OEM Lock vs FRP Lock (Important Difference)
If you also see FRP Lock: ON in Down
Samsung FRP (Factory Reset Protection) fix
🔐 On Samsung phones, FRP (Factory Reset Protection) is activated when the device is reset without removing the Google (Gmail) account first. Bypassing FRP depends on the phone’s Android version and security patch level.
🛠️ Below are some common and working methods:
📞 Method 1: “Emergency Call” Method (Newest & Easiest)
This method works on many latest Samsung models running Android 11, 12, 13, and 14.
- 📲 On the Welcome screen, tap Emergency Call.
- ⌨️ Dial the code:
*#0*# - 🧪 A test menu (white screen) will open.
- 💻 Connect the phone to a PC and download a free tool such as SamFw Tool or ZeroKnox Removal Tool.
- 🖱️ In the tool, click Remove FRP.
- 🔓 When “Allow USB Debugging” appears on the phone, check it and tap OK.
- ✅ The tool will automatically remove FRP and restart the phone.
🗣️ Method 2: TalkBack / Browser Method (Older Android)
If the code method does not work, older Android versions may use this approach:
- 📶 Connect the phone to Wi-Fi.
- 🔊 Press Volume Up + Power to enable TalkBack.
- ✏️ Draw an inverted “L” on the screen, select Voice Commands, and say: “Open Google Assistant”.
- ▶️ When Assistant opens, say: “Open YouTube”.
- 🌐 Go to YouTube settings and tap Terms of Service to open the browser.
- 🔎 Search for AddROM or VnROM and choose Open Settings.
- 🔐 Try setting a new screen lock (PIN / Pattern).
🛡️ Method 3: Alliance Shield X (Android 11 / 12)
If you can access Settings but cannot remove FRP:
- 📱 You will need another Samsung phone with Alliance Shield X installed.
- ☁️ Take a backup of that phone to Samsung Cloud and restore it on the FRP-locked device.
- ⚙️ Using the app, enable Knox and Service Mode to bypass FRP.
💼 Method 4: Paid Tools (If Nothing Works)
If free methods fail, technicians usually use professional tools:
- 💳 ChimeraTool
- 🔓 UnlockTool
- 🧰 Octoplus / Z3X Box
💡 Tip: If you remember your old Google account, simply connect to Wi-Fi and sign in with the original email and password — FRP will be removed automatically.
Samsung Reactivation Lock
🔐 On Samsung phones, Reactivation Lock (Samsung Account Lock) is a security feature that usually appears on older models and devices running up to Android 8.0 Oreo. Below is a detailed explanation of the common methods used to remove it.
🧪 Method 1: Combination File Method (Most Professional Solution)
If the phone is stuck on the setup screen and cannot proceed, this is the most reliable method:
- 📥 Step 1: Download the correct Combination File according to your phone’s model and Binary Level (U1, U2, etc.), then flash it using Odin in the AP slot.
- ⚙️ Step 2: Once the phone boots, it will open in a special factory (Binary OS) menu. Go to Settings, enable Developer Options, and turn ON OEM Unlocking and USB Debugging.
- 🔁 Step 3: Reboot the phone into Download Mode again and flash the full 4-file Stock Firmware. After reboot, the Reactivation Lock will be removed.
🌐 Method 2: Browser Bypass Method (Without PC)
If you don’t have access to a PC, you can try reaching the browser through system loopholes:
- 📶 Wi‑Fi Connection: Connect the phone to Wi‑Fi on the setup screen.
- 🗣️ Access Browser: Enable TalkBack or use Emergency Call to reach Google Chrome or Samsung Browser.
- 🔎 Bypass Page: Search for vnROM bypass or AddROM, then select Open Settings.
- 👤 Account Action: In Settings, try adding a new Samsung account or go to Security settings and disable Find My Mobile.
🧰 Method 3: Professional Unlock Tools (One‑Click Solution)
If you visit a repair shop or have access to professional software, this is the fastest method:
- 🧰 Z3X / Octoplus Box: Connect the phone in Download Mode and click Reset Samsung Account / Reactivation. The tool resets the security partition (EFS / Param).
- 💻 SamFw Tool (Free PC Tool): Includes a Remove Samsung Account option that works in ADB mode.
📋 Important Checklist
- 📌 Binary Level: Always flash firmware that matches your phone’s binary version, otherwise you will get a Binary Check Fail error.
- 🗑️ Data Loss: All these methods will completely erase user data.
- 🔑 FRP vs Reactivation: If the phone asks for a Google account, it’s FRP. If it asks for a Samsung ID, it’s Reactivation Lock. The methods are similar, but files/tools may differ.
