FIX FORCED ENCRYPTION AND 0 MB INTERNAL STORAGE TWRP AND ORANGEFOX

Fix Forced Encryption and 0 mb Internal Storage Twrp & OrangeFox

We understand the frustration that arises when you attempt to modify your Android device’s system, only to encounter cryptic errors regarding forced encryption and internal storage that appears to be 0 MB. These issues are common barriers in the custom ROM and rooting community, particularly when utilizing custom recovery solutions like TWRP (Team Win Recovery Project) or OrangeFox Recovery. Our goal is to provide a definitive, comprehensive guide to resolving these specific anomalies, ensuring that your custom recovery environment functions exactly as intended.

Understanding the Root Cause: Encryption and Storage Partitioning

To effectively solve the problem, we must first dissect the underlying mechanisms of modern Android devices. Since the introduction of Android 6.0 Marshmallow, Google mandated that devices shipping with the Hardware-backed Keystore feature must utilize file-based encryption (FBE) or, in older implementations, full-disk encryption (FDE). This security measure encrypts the user data partition immediately upon the first boot.

When you flash a custom recovery like TWRP or OrangeFox, the recovery environment needs to be able to read and write to the /data partition to perform backups, restore data, and flash modifications. However, if the /data partition is encrypted with a key that the custom recovery does not possess or cannot access, the recovery software sees the partition as raw, unreadable data. This results in the “0 mb Internal Storage” error. The recovery cannot mount the filesystem because it is encrypted, leading it to display the available space as zero or fail to mount entirely.

The “Forced Encryption” issue is often a kernel-level behavior. Many stock kernels are configured to automatically re-encrypt the data partition if they detect that the encryption flag has been removed or if the system detects a change in the partition structure. This creates a loop where the user formats data to decrypt it, only for the device to re-encrypt it upon the next boot, locking the user out of their custom recovery’s full functionality.

Prerequisites for Modifying Device Partitions

Before proceeding with any modifications to the boot.img or recovery partitions, we highly recommend that users ensure they have the necessary tools and backups. This process carries inherent risks, including the potential for boot loops or data loss.

  1. Unlocking the Bootloader: This is the first and most critical step. A locked bootloader prevents the installation of unsigned images like TWRP or OrangeFox. The method varies by manufacturer (e.g., Xiaomi, OnePlus, Samsung).
  2. ADB and Fastboot Tools: You must have the Android Platform Tools installed on your computer to interface with your device in Fastboot mode.
  3. The Correct Custom Recovery Image: Ensure you have the specific TWRP or OrangeFox image file designed for your exact device model and codename. Using an incorrect image can result in a hard brick.
  4. Disable Device Encryption via Flags: Most modern rooting methods utilize a patch to the boot.img (using Magisk or KernelSU) that includes a command to disable forceencrypt or forcefdeorfbe flags in the kernel command line.

Solving the 0 MB Internal Storage Issue in TWRP

The most common reason TWRP shows 0 MB internal storage is the inability to mount the encrypted data partition. We address this by formatting the data partition to remove the encryption key. However, we must do this without triggering a re-encryption cycle.

Method 1: Formatting Data via TWRP (The Decryption Step)

If you can boot into TWRP, the immediate solution is to wipe the data partition correctly. A simple “Swipe to Factory Reset” often does not suffice because it may not remove the encryption footer or the fec (File-Based Encryption) metadata.

  1. Boot into TWRP.
  2. Navigate to Wipe > Advanced Wipe.
  3. Select the Data or Internal Storage partition (depending on your TWRP version, it might be labeled differently).
  4. Tap on Repair or Change File System.
  5. Tap Change File System.
  6. Select Ext4. This is the standard unencrypted file system. F2FS is also acceptable, but Ext4 is generally more stable for this specific fix.
  7. Swipe to confirm the change.
  8. Go back to the main wipe screen and perform a standard Swipe to Factory Reset.

This process reformats the partition and removes the encryption metadata. When TWRP restarts or remounts the partition, it should now see the full capacity of your storage because it is mounting an unencrypted Ext4 partition.

Method 2: Handling Encryption Flags in Magisk Modules

Sometimes, simply formatting data is not enough if the underlying kernel insists on encryption. This is where the rooting method comes into play. If you are using Magisk, the standard installation method patches the boot.img to include the verity and forceencrypt flags.

If you are flashing a custom ROM that forces encryption (like some versions of LineageOS or stock-based ROMs), you may need to modify the fstab file in the recovery ramdisk. However, for most users on Magisk, the issue is solved by ensuring the forceencrypt flag in the kernel command line is set to forceencrypt=0 or forcefdeorfbe=0.

If you are using a Magisk Module to handle encryption, ensure that the module is active. Our repository at Magisk Modules contains modules specifically designed to manage encryption behavior. These modules work by modifying the mount points in the recovery environment to ignore the encryption requirement.

Addressing Forced Encryption in OrangeFox Recovery

OrangeFox Recovery is a fork of TWRP with additional features, but it shares the same underlying architecture regarding encryption. The “Forced Encryption” issue is usually prevalent when users attempt to flash a custom ROM without first decrypting their data or without including the necessary decryption scripts in the ROM zip.

The OrangeFox “Magisk Overlay” Fix

OrangeFox has a unique feature called the “Magisk Overlay” system. It allows the recovery to boot with a separate set of mount points that prioritize Magisk’s mount logic. If you are facing forced encryption issues in OrangeFox:

  1. Ensure you have the latest version of OrangeFox for your device.
  2. Boot into OrangeFox.
  3. Navigate to Settings > Magisk.
  4. Ensure that “Add Magisk to recovery” is checked if applicable, but more importantly, check for “Force Encryption” settings in the OrangeFox configuration menu.
  5. OrangeFox often includes a specific zip (often named OrangeFox-encryption-fix.zip or similar) that needs to be flashed before the ROM to ensure the ro.crypto.state variable is set correctly to unsupported or unencrypted.

Fixing the fstab in OrangeFox

Forced encryption is strictly defined in the fstab file. If your recovery’s fstab contains the forceencrypt flag, it will attempt to mount an encrypted partition. OrangeFox allows you to edit the fstab directly from the recovery interface.

  1. In OrangeFox, go to Advanced > File Manager.
  2. Navigate to /etc or /system/etc (depending on your device layout).
  3. Look for fstab.qcom or fstab.default.
  4. Select Mount > Read Only to make it writable.
  5. Select Edit.
  6. Look for the line mounting /data. It likely looks like: /dev/block/by-name/userdata /data ext4 noatime,wait,forceencrypt=footer
  7. Change forceencrypt=footer to encryptable=footer or simply remove the forceencrypt flag entirely, leaving it as noatime,wait.
  8. Save the file and reboot recovery.

Advanced Troubleshooting: The vbmeta.img Factor

On newer devices (Android 10 and above, particularly Xiaomi and Samsung), the vbmeta (Verified Boot Meta) partition plays a crucial role in enforcing encryption and AVB (Android Verified Boot) 2.0.

If you are stuck in a boot loop after trying to disable encryption, or if your recovery consistently shows 0 MB storage even after formatting, you may need to disable verification via vbmeta.

Flashing vbmeta with Disverification

This requires the vbmeta.img extracted from your firmware or provided by your device’s developer community.

  1. Reboot your device into Fastboot Mode.
  2. Connect your device to your PC.
  3. Execute the following command:
    fastboot flash vbmeta --disable-verity --disable-verification vbmeta.img
  4. Then flash your custom recovery (TWRP/OrangeFox) again:
    fastboot flash recovery twrp.img
  5. Reboot directly into recovery (do not boot into system yet).

By disabling verification, you prevent the bootloader from checking the integrity of the system and data partitions. This effectively stops the system from forcing encryption or preventing the boot process due to a modified fstab.

Persistent “0 MB” Storage? Check Dynamic Partitions (A/B Slots)

If your device uses A/B Partitioning and Dynamic Partitions (Super Partition), the internal storage issue can be related to how the recovery handles the super partition mounting.

When OrangeFox or TWRP fails to mount the super partition correctly, it can cause the userdata partition to be unmountable, resulting in the 0 MB display.

The Fix:

  1. Boot into recovery.
  2. Go to Wipe > Format Data (not just wipe, but format).
  3. Type yes to confirm.
  4. Reboot to recovery.
  5. Go to Advanced > Partition SD Card or Fix Contexts (in OrangeFox).
  6. Select “Fix Contexts / Metadata”. This re-applies the SELinux contexts and file system metadata that often get corrupted during the decryption process.

Android encryption stores a header (or footer) at the end of the data partition. If this header is corrupted or retained while the partition is formatted to Ext4, the system may still believe the partition is encrypted.

To completely wipe this header:

  1. Boot into TWRP/OrangeFox.
  2. Go to Advanced > Command Prompt.
  3. Type: dd if=/dev/zero of=/dev/block/bootdevice/by-name/metadata bs=1 count=1024 (Note: Be extremely careful with this command. The partition name ‘metadata’ or ‘userdata’ varies by device. Using dd incorrectly can wipe your IMEI or EFS).

A safer method within the recovery interface is to use the “Wipe” function and select “Format Data”. This typically executes a mkfs.ext4 command which overwrites the filesystem signature, effectively removing the encryption footer without risking raw block device manipulation.

Summary of the Workflow

To ensure a successful fix for Forced Encryption and 0 mb Internal Storage Twrp & OrangeFox, we recommend the following workflow:

  1. Prepare: Unlock bootloader, install ADB/Fastboot.
  2. Patch: If using Magisk, patch your boot.img to ensure forceencrypt flags are removed.
  3. Disable Verification: Flash vbmeta with --disable-verity --disable-verification if your device requires it.
  4. Install Recovery: Flash the latest TWRP or OrangeFox.
  5. Format Data: Boot immediately into recovery and perform a Format Data (Type yes) operation to wipe encryption keys.
  6. Install Modules: Browse the Magisk Module Repository for any device-specific encryption fix modules if the issue persists.

By following these detailed steps, we ensure that the custom recovery environment has full, unencumbered access to the internal storage, bypassing the strict encryption protocols enforced by stock Android kernels. This allows for a seamless custom ROM installation, rooting experience, and system modification process.
