🔐 What is DRK?
Device Root Key (DRK) is an encrypted number stored in Samsung devices that helps the system verify whether the device is official or tampered. A missing or corrupted DRK can prevent your phone from booting properly, cause hang on logo, bootloops, or errors in Recovery Mode.
⚠️ When This Error Occurs?
This error happens when the Bootloader detects unauthorized changes in the file system, when the DRK key does not match official binaries, or if someone flashes a custom ROM incorrectly. Even small firmware mismatches can trigger DM-Verity or DRK-related issues.
❗ Problems Caused by DRK Issues
If the system detects a DRK problem, your device may experience:
🔄 Bootloop
🟢 Hang on LOGO (Samsung animation or first logo)
♻️ Auto reboot to Recovery Mode

Charge your phone at least 50% before starting. All steps should be performed at your own risk. During the repair, all personal data (files, photos, documents, apps) may be erased. Follow instructions carefully to avoid further errors.
❓ What is DRK?
🚀 DRK (Device Root Key) is a unique hardware-based security key embedded in Samsung devices to ensure the system's integrity. Think of it as a "Digital Fingerprint" that verifies if your Android OS is official and untampered.
⚠️ Why does it fail? The "DRK Failed" error usually occurs when the system detects a mismatch between the hardware key and the software. This often happens due to:
- ❌ Corrupted EFS Partition: Loss of critical network and security data.
- ❌ Interrupted Updates: Phone turning off during an Android 8.0 Oreo update.
- ❌ Rooting Attempts: Using incorrect files while trying to unlock the device.
- ❌ Binary Mismatch: Flashing a firmware that doesn't match the U4 (Binary 4) level.
🧩 Corrupted EFS Partition
The EFS partition stores critical device information such as IMEI, network configuration, and security data. If the EFS partition becomes corrupted due to improper flashing, firmware mismatch, or failed root/custom ROM installation, it can cause DRK and DM-Verity errors, network issues, bootloop, or no signal problems. Repairing or restoring the correct EFS data is essential for the device to boot and function properly.
🔢 Binary Mismatch
Binary mismatch occurs when a firmware with a different binary version is flashed on the device, such as installing a lower or higher binary than supported. This causes the bootloader to reject system files, leading to DRK or DM-Verity failed errors. As a result, the phone may get stuck on the Samsung logo, enter a bootloop, or fail to boot completely. Always flash firmware and DRK repair files that match the exact binar
🧑💻 Rooting Attempts
Failed or incomplete rooting attempts can modify protected system partitions and break device security checks. When rooting is not done properly, it may corrupt the DRK key or trigger DM-Verity protection, resulting in bootloop, hang on logo, or automatic reboot to Recovery
⏸️ Interrupted Updates
Interrupted or incomplete software updates can damage system files and cause DRK or DM-Verity errors. This usually happens when the device powers off during an update, the battery dies, or the internet connection is unstable. As a result, the phone may get stuck on the Samsung logo, enter a bootloop, or repeatedly restart into Recovery Mode. Re-flashing the correct firmware and DRK repair files is often required to resolve this i
✅ The Solution: To fix this on the Samsung J5 Prime (G570F), you must flash a specific "DRK Fix" file or a combination firmware that matches your Binary version (U4). This restores the link between the hardware key and the system software, allowing the device to boot normally.
🔐 Device Root Key (DRK) is an encrypted number used by the device for system identification. It helps determine whether the device is official or tampered.
❓ When This Error Occurred?
🕒 Failed Firmware Updates: This error most commonly occurs when an official Android 8.0 Oreo update is interrupted due to a poor internet connection or the phone powering off during the installation process.
📂 Incompatible Binary Flashing: If you try to flash a lower binary firmware (like U1, U2, or U3) on a Binary U4 device, the system triggers a DRK or dm-verity fail to protect the hardware from downgrading.
🔓 Rooting & Custom Recovery: Attempting to install TWRP, Magisk, or custom ROMs while FRP (Factory Reset Protection) or OEM Lock is still ON will immediately result in a security block and the "dm-verity failed" message.
🛠️ System Partition Corruption: Sudden system crashes or hardware issues in the EFS/NV data partitions can cause the Device Root Key to become unreadable, leading to a permanent boot loop in recovery mode.
⚠️ This error occurs whenever the Bootloader detects custom changes in the file system, a DRK key mismatch with official binaries, or when someone flashes a custom ROM improperly.
What Problems Are Initiated by DRK?
🔄 Stuck in Boot Loop: The most immediate problem is that your Samsung J5 Prime will fail to reach the home screen. It will either keep restarting at the "Samsung Galaxy J5 Prime" logo or automatically boot into Recovery Mode every time you power it on.
🛑 Recovery Mode Errors: When you enter the recovery menu, you will see
a bright red error message stating
"dm-verity verification failed" or
"Need to check DRK first". This prevents you from performing a
standard factory reset or clearing the cache effectively.
📡 Network & IMEI Issues: Since the DRK is closely linked to the EFS partition, a corrupted DRK can lead to the loss of network signals. In some cases, the device may show "No Service" or "Invalid IMEI" even after you manage to bypass the boot error.
📴 System Instability: Even if the device boots up using temporary bypass methods, you may experience frequent system UI crashes, random freezes, and the inability to use secure features like Samsung Pass or Secure Folder.
🛠️ Flashing Restrictions: A DRK error often makes the device "Write Protected" in Odin. This means you cannot flash standard firmware easily, especially when FRP and OEM locks are active, making the repair process more complex for Binary U4 users.
❗ When the system detects a DRK problem, it may cause one of these issues:
- 🔄 Bootloop
- 🟢 Hang on LOGO (First logo, or Samsung animation)
- ♻️ Auto reboot to Recovery Mode
🛠️ How to Fix/Bypass DRK (DM-Verity Error) on G570F U4
To fix the DRK and dm-verity failed error on Samsung J5 Prime Binary U4, follow these steps carefully. Make sure your phone has at least 50% battery before starting.
✅ Step 1: Download Required Files First, you need to download the Samsung J5 Prime G570F U4 Combination ROM or a specific DRK Fix File that matches your Binary version (U4). Standard firmware might not work if the integrity is already compromised.
📲 Step 2: Enter Download Mode Turn off your device completely. Press
and hold the Volume Down + Home + Power buttons simultaneously. When
the warning screen appears, press Volume Up to enter Download Mode. You
should see FRP LOCK: ON and OEM LOCK: ON.
💻 Step 3: Setup Odin Tool Open Odin3 on your PC and connect your phone via a high-quality USB cable. The ID:COM box in Odin should turn blue, indicating that your device is successfully connected.
📂 Step 4: Flashing the Fix File Click on the AP (or PDA) button in Odin and select the DRK Fix file or Combination file you downloaded. Make sure only "Auto Reboot" and "F. Reset Time" are checked in the options tab. Click Start to begin the process.
🎉 Step 5: Final System Flash Once the fix file is flashed and the device boots up (it might show a technical test menu), you must flash the Full Official Firmware (4-Files: BL, AP, CP, CSC) of Android 8.0 Oreo Binary U4. This will permanently restore the DRK signature and fix the dm-verity error.
⚠️ Warning
- 🔋 Charge your phone at least 50% before starting
- 📥 Download the same version firmware and fix file
- ⚠️ Perform all steps at your own risk
- 💾 Data (Files, Photos, Documents, etc.) will be erased
Note: If you are still getting the error, try to "Wipe Cache Partition" from the recovery mode after flashing. This often clears residual system conflicts.
