Locked (Verified): The default factory state. It ensures that only official, signed software from Sony can run on the device.

Unlocked: Disables the security check, allowing you to flash custom kernels and recoveries like TWRP or ClockworkMod.

Relocked: Restores the device to a "locked" state, which is often required for receiving official OTA updates or restoring the device for warranty purposes. 2. Checking Unlock Eligibility

On modern Xperia devices (Xperia 1 series and newer), the concept of "verified" boot and relocking has changed significantly: Relocking Capability

: Unlike older models, modern Xperia phones (Xperia 1 and newer) can be relocked via command line or

: Unlocking often permanently loses some DRM keys (like those for high-quality Netflix or specialized camera features). While relocking may restore some functionality, the "Verified" status in the service menu will permanently record that the device "has ever been unlocked".

To unlock or relock the bootloader on a Sony Ericsson (SE) or modern Sony Xperia device, you must first verify if your specific handset supports this modification. Unlocking allows you to install custom ROMs or gain root access, but it will wipe all user data and typically voids the warranty. Verification: Check if Unlock is Allowed

For legacy Sony Ericsson (SE) enthusiasts, the challenge of modifying older Xperia devices often comes down to one status: 167z Verified. This specific term typically refers to the hardware and software verification status of the bootloader, particularly on older SEMC (Sony Ericsson Mobile Communications) platforms.

If your device's service menu shows "Bootloader unlock allowed: Yes" but the bootloader status remains stuck or unverified, this guide covers the verified methods to unlock and relock your device. Step 1: Check Your Unlocking Status

Before attempting any modification, you must verify if your specific hardware allows bootloader manipulation. Open the Dialer app on your device. Enter the service code: *#*#7378423#*#*. Navigate to Service info > Configuration > Rooting Status. Look for Bootloader unlock allowed:

Yes: You can proceed with the official or unofficial methods.

No: Your bootloader is likely carrier-locked, and standard software tools may not work without a "test point" hardware bypass. Step 2: Unlocking the Bootloader (Official Method)

If your status is "Yes," use the official Sony developer portal for a clean unlock. Get your IMEI: Dial *#06# and write down the 15-digit code. The Origin of "Verified" in Bootloader Tools In

Based on the context of the keywords (specifically "167z" and "SE"), this topic refers to the Sony Xperia XZ1 Compact (model number G8441, often associated with the customization number "167z" in service menus) and the process of managing its bootloader state.

Here is a useful, technical review of the process and status for this specific device.

The Origin of "Verified" in Bootloader Tools

In official unlock processes (e.g., Xiaomi’s Mi Unlock), the term "verified" appears when your account passes a device-specific challenge. The "167z" variant is almost never mentioned in official documentation. Instead, it appears in community-modified unlocking tools.

Tools like SE Unlock Tool, Hydra Tool, or UnlockTool (popular in GSM service centers) use codenames like "167z" to represent a specific bootloader anti-rollback version. When a tool says "167z verified," it means:

The tool has queried the device’s bootloader version.
It matched a known exploit or token for that version.
The unlock procedure proceeded without triggering the "Account not authorized" error.

Common "167z Verified" Relocking Failures:

| Error Message | Cause | Solution | |---------------|-------|----------| | Flashing lock is not allowed | Modified system partition | Re-flash full stock ROM | | Image is not signed | Custom kernel or recovery | Find official 167z images | | Verity failed (hash mismatch) | vbmeta mismatch | Use OEM's vbmeta with disable flags removed | | Device rolled back | Downgraded to older build | Must flash exactly 167z or newer |

Part 2: Understanding "167z Verified"

The string "167z" likely refers to a software branch (e.g., V12.5.167z or Build 167z-release-keys). The "Verified" suffix confirms that the boot process runs Android Verified Boot (AVB) 2.0 or higher with:

vbmeta verification (ensures partitions aren't corrupted)
Chain of trust starting from the bootloader to the kernel.

What does "SE" mean in bootloader contexts?

"SE" typically stands for Special Edition or Security Enhanced, depending on the manufacturer. In the Xiaomi ecosystem (which dominates bootloader discussions), "SE" often refers to devices with modified bootloader policies, such as the Xiaomi 12 SE or regional variants with extra anti-rollback protections. In other contexts, "SE" denotes SELinux (Security-Enhanced Linux) enforcement, which complicates unlocking.

When you see "SE bootloader," it implies a locked bootloader with additional OEM security layers beyond the standard Android Verified Boot (AVB).
