Oem-locked Cid 0x0032 ◎

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.

Before we attack the problem, we need to understand the terminology. oem-locked cid 0x0032

Connect your phone to a PC and run the command: fastboot getvar cid Alternatively, fastboot getvar all will show the CID along with other device details. Why "OEM Unlocking" Might Be Greyed Out If your device shows this status after a

, users frequently face a "deadlock" where the hardware is capable of being unlocked, but the software prevents it. The "OEM Unlock" Deadlock The most common issue for CID 0x0032 users is the greyed-out "OEM Unlocking" toggle Why "OEM Unlocking" Might Be Greyed Out ,

To check if your 0x0032 device can be unlocked, follow these steps: 1. Enable Developer Options Go to .

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 (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.”

For developers and researchers, it means the attack surface has shifted. We are no longer looking for bugs in the bootloader logic; we are looking for vulnerabilities in the TrustZone, the cryptographic implementations, or the hardware interfaces themselves.
