In the world of Android customization, few things are as frustrating as hitting an unlockable bootloader. You’ve just bought a new (or used) phone, you’re ready to flash a custom ROM, gain root access, or recover data from a semi-bricked device. You fire up the command prompt, type fastboot oem unlock, and wait.
Instead of success, you are greeted with a cryptic error:
"OEM-Locked"
"CID: 0x0032"
If you are seeing this combination, you have hit one of the most restrictive hardware-level locks in the Android ecosystem. This article will explain exactly what CID 0x0032 means, which manufacturers use it, why it behaves differently than other locks, and—most importantly—your realistic options for bypassing it.
Short answer: No.
If you are reading this article because you are considering buying an AT&T-branded Motorola or Lenovo device, do not buy it. The oem-locked cid 0x0032 error is a permanent hardware-level sentence to stock firmware. No amount of forum searching, paid tools, or desperate ADB commands will bypass it on modern devices (Android 11+).
If you already own such a device:
If you need an unlockable phone:
The cid 0x0032 is a reminder that your phone is not truly yours—it is a leased device permanently configured to serve the carrier's interests over your freedom to tinker. Choose your next phone wisely.
In the stratified ecosystem of mobile computing, few identifiers carry as much weight—or as many frustrations—as the Controller Identification (CID) of an eMMC (embedded MultiMediaCard) storage chip. While seemingly arcane, this 32-bit register dictates the fundamental relationship between a device’s hardware and its operating system. Among the myriad of possible values, the specific code 0x0032 stands as a paragon of corporate control: the OEM-locked CID. This essay explores the technical function of the CID, the meaning of the 0x0032 vendor lock, and its profound implications for device ownership, repair, and software freedom.
To understand the significance of 0x0032, one must first understand the CID’s role. The CID is a unique, factory-programmed identifier within every eMMC device. It contains critical metadata: the manufacturer ID, product name, serial number, and most critically for this discussion, the OEM ID (bits 112-120). When a bootloader or operating system initializes the storage, it reads the CID to authenticate the hardware. In an unlocked or generic device, this value is mutable or irrelevant. However, in an OEM-locked system, the bootloader is hard-coded to only proceed if the CID matches a specific, vendor-authorized value. The code 0x0032 is not a universal constant (it varies by manufacturer, e.g., Samsung or Sandisk), but in the context of lock discussions, it represents a specific vendor’s designation—a digital handshake that says, “This storage chip is approved for this device.”
The locking mechanism tied to 0x0032 is fundamentally a cryptographic handshake. When the device powers on, the bootloader issues a command (CMD9 for CID) to the eMMC. It reads the returned 16-byte CID and compares the OEM ID field. If the value matches the hardcoded 0x0032 (or whatever the vendor expects), the boot process continues to load the kernel. If it does not—if a user attempts to replace a failed eMMC with a generic, off-the-shelf chip—the bootloader halts, often displaying a “Device Unlocked” warning or simply refusing to boot. This lock is not a bug; it is a deliberate feature designed to create a closed hardware ecosystem.
The practical consequences of the 0x0032 lock are severe, particularly in the realm of device longevity. Consider a tablet or smartphone whose internal storage fails after two years. In an open PC architecture, one would simply replace the SSD. In an OEM-locked device with CID 0x0032, replacement is impossible with standard tools. The new eMMC, while electrically identical, will have a different CID. The bootloader will reject it, leaving the device a brick. The only recourse is to obtain a factory-programmed chip from the OEM—often priced prohibitively or unavailable to the public—or to solder the original, failed chip’s controller onto a new board, a feat requiring microscopic soldering and reverse-engineering. Thus, a $10 eMMC failure can destroy a $500 device, not due to physical impossibility, but due to a single, locked register.
Furthermore, the 0x0032 lock acts as a bulwark against software freedom. Custom ROM communities, such as those for LineageOS or GrapheneOS, often require replacing the vendor-supplied operating system. While unlocking the bootloader is a standard first step, an OEM-locked CID adds a secondary barrier. Even with an unlocked bootloader, some devices cross-check the CID against a whitelist. If 0x0032 is present but the software is not signed by the OEM, the system may enter a “restricted mode,” throttling performance or disabling hardware features like the camera or modem. This transforms the CID from a mere identifier into an active enforcement agent of the OEM’s software monopoly.
The justification for such a lock is, on its surface, security. OEMs argue that 0x0032 and similar locks prevent malicious actors from replacing storage with a compromised chip that could exfiltrate data or inject rootkits. In high-security environments (e.g., corporate MDM or government devices), this is a valid concern. Additionally, the lock ensures that only qualified, validated storage chips—tested for thermal and electrical compatibility—are used, preventing instability from third-party parts. However, these justifications crumble under the right-to-repair lens. Security through lock-in is a fragile argument when it simultaneously prevents a user from replacing a worn-out component with an identical, generic part.
In conclusion, the OEM-locked CID 0x0032 is a microcosm of the tension between manufacturer control and consumer ownership. It is a single byte within a 16-byte register, yet it holds the power to grant or deny a device’s life. For the average user, it is invisible—until the day their device dies a premature death from a failed storage chip. For the enthusiast, it is a wall. And for the environment, it is a contributor to e-waste, as perfectly functional motherboards are discarded because a tiny, lockable identifier says “no.” The battle over CID 0x0032 is not merely technical; it is a legal and ethical struggle over whether we truly own the hardware we pay for, or whether we are merely renting it at the pleasure of the OEM’s digital deadbolt.
Understanding the "OEM-Locked CID 0x0032" status is critical for Android enthusiasts and developers working with Motorola devices. This specific CID (Carrier Identifier) is a common roadblock when attempting to unlock bootloaders for customization. What is CID 0x0032?
The CID is a piece of metadata stored in a device's read-only partition. It identifies the original carrier or region for which the phone was manufactured. Identifier: 0x0032. Primary Carrier: Amazon (Prime Exclusive editions).
Secondary Carriers: Certain TracFone or Verizon-linked variants.
Purpose: Enforces software restrictions and prevents unauthorized firmware changes. The Problem: "OEM-Locked" Status
When you see the message "Status: OEM-Locked" alongside CID 0x0032, it means the device is hard-blocked from bootloader unlocking. Why this happens
Most Motorola phones can be unlocked using a code from the Motorola Support website. However, Motorola’s database specifically flags CID 0x0032 as "not eligible." This is usually due to contractual agreements between the manufacturer and the retailer (like Amazon) to keep the software ecosystem closed in exchange for a lower device price. Technical Implications 1. Bootloader Restrictions
The command fastboot oem get_unlock_data may still provide a string, but submitting it to Motorola will return a "Device is not eligible" error. 2. Firmware Limitations You cannot flash Custom ROMs (LineageOS, Pixel Experience).
Rooting via Magisk is generally impossible because you cannot flash a patched boot image. You are restricted to official OTA (Over-the-Air) updates. 3. "The Amazon Bloat"
For many users, 0x0032 is synonymous with Amazon-branded apps and lock-screen ads. While ads can often be removed via settings or ADB, the underlying CID remains unchanged. Can you change CID 0x0032? In short: Rarely.
Changing a CID requires "S-OFF" (Security Off) status or access to the device's "pds" or "config" partitions, which are protected by the locked bootloader. It creates a "chicken and egg" problem: You need an unlocked bootloader to change the CID. You need to change the CID to unlock the bootloader. Potential Workarounds
Blankflash Files: In some older models, using a "blankflash" tool during an unbrick process could occasionally bypass CID checks, though this is risky and often leads to hard bricks.
Paid Services: Some third-party remote unlocking services claim to bypass CID restrictions using proprietary server-side tools. Success rates vary wildly.

If you are looking to purchase a Motorola device for modding, avoid CID 0x0032. Look for "Retail" variants (CID 0x0031 or similar) which are typically eligible for the Motorola Bootloader Unlock program.
💡 Pro Tip: Always check your CID in Fastboot mode by typing fastboot getvar all before attempting any modification.
"OEM-locked cid 0x0032" is a technical status typically found on Motorola devices (such as the Moto Edge 40 Pro or Moto G7 series). It indicates that the device's bootloader is currently locked and the "Carrier ID" (CID) is set to a specific retail or regional variant. What This Status Means
OEM-locked: The bootloader is locked, preventing you from flashing custom operating systems or unofficial firmware.
CID 0x0032: This specific hex code identifies the device as a Retail/International variant (often associated with the "Retail" or "Global" software channel). Devices with this CID are generally eligible for bootloader unlocking through the Motorola Bootloader Unlock site, unlike some carrier-specific models (like Verizon or AT&T) which may be permanently locked. Common Issues & Troubleshooting
If you are seeing this while trying to modify your device, users in technical communities like r/androidroot and the /e/OS Forum have identified these common scenarios:
Missing OEM Unlock Toggle: If the "OEM Unlocking" option is greyed out in Developer Options, you may need to connect to Wi-Fi and wait for several days for the system to verify the device's eligibility.
Command Failure: Running fastboot flashing unlock will fail unless you have first obtained a unique Unlock Key from Motorola's website and toggled "OEM Unlocking" in your phone's settings.
No OS Found: If your device shows this status after a failed update, you might need to use the Lenovo Rescue and Smart Assistant (RSA) tool to reflash the stock firmware.
Connection Errors: Some Motorola devices have trouble with USB 3.0 ports in fastboot mode; using a USB 2.0 port or hub often resolves communication failures.

The OEM-locked CID 0x0032 status refers to a specific identification code (Carrier Identification ID) found on Motorola devices. This code typically identifies a device as "Retail" or "Unbranded," which should theoretically make it eligible for bootloader unlocking. However, users often encounter errors or grayed-out options when attempting to customize these phones. Understanding CID 0x0032
Definition: CID stands for Carrier ID. The value 0x0032 is a hex code that identifies the original intended distributor or region of the Motorola firmware.
General Eligibility: In the Motorola ecosystem, 0x0032 is usually categorized as a "Retail" version. Unlike carrier-locked variants (like those from Verizon), retail versions are generally permitted to participate in the Motorola Bootloader Unlock program. Why "OEM Unlocking" Might Be Grayed Out
Even with an eligible CID, the "OEM Unlocking" toggle in Developer Options may be unavailable for several reasons:
Connection Requirement: For newer Motorola devices, the "OEM Unlocking" toggle may remain grayed out until the device has been connected to the internet for a specific duration—sometimes up to seven days.
Carrier Residuals: While 0x0032 is a retail CID, some devices sold through third-party retailers like Amazon or eBay may have been refurbished from carrier versions or have regional locks that override the retail CID's standard permissions.
System Integrity: If the device has previously undergone unsuccessful flashing attempts, the bootloader might remain "Securely Locked," preventing further modification. Troubleshooting the "Not Eligible" Error
If Motorola's website reports your 0x0032 device is not eligible after running the fastboot oem get_unlock_data command:
Format the String: Ensure the unlock data string is pasted as one continuous line with no spaces or "bootloader" prefixes.
Verify Motorola Privacy Settings: Ensure all options under Settings > Privacy > Motorola Privacy are enabled to allow the device to sync with Motorola's servers.
Check for Regional Blocks: Certain regions (like Canada or specific European markets) might have restricted eligibility despite having a retail CID. Risks and Considerations
