Back to FeaturesEvery mobile device is identified by a unique IMEI number, which allows carriers to authenticate it on the network. This 15-digit code ensures your phone can make calls, send texts, and access mobile data securely.
A valid IMEI protects both users and networks. Carriers can track and block lost or stolen devices, preventing unauthorized access and keeping networks safe.
If an IMEI is missing or corrupted, the phone may struggle to connect to networks, be denied service, or even be blacklisted. This reduces the device’s functionality, lowers resale value, and can affect access to future software updates.
On Samsung devices, repairing or modifying the IMEI may require root access, while in North America, bootloader restrictions make the process more complex. To ensure compatibility, technicians should always check the list of supported versions on the Chimera Tool website before starting.
Even though the IMEI number is meant to be permanent, there are several situations where it can be lost, corrupted, or overwritten.
A failed update or an incomplete flash can overwrite the IMEI storage area, leaving the device without a valid identifier. In some cases, rooting or using unauthorized tools may also compromise the IMEI, causing the phone to appear as “null” or “unknown” to the network.
Motherboard replacements or internal repairs can also affect the IMEI if not performed correctly. In other cases, using unofficial or poorly built tools may damage the IMEI, making it unreadable by the network.
Chimera Tool is designed to restore a phone’s original IMEI safely and effectively.
A professional IMEI repair solution restores the device’s original IMEI, ensuring it regains full access to calls, texts, and mobile data.
This not only fixes connectivity problems but also preserves the phone’s resale value, making it as reliable as it was when it first left the factory. For repair shops, offering proper IMEI repair means delivering a complete service that customers can trust.
The Repair IMEI feature in Chimera Tool restores a phone’s original IMEI number. On some devices, normal restoration allows the IMEI to be written directly; however, on newer models, Chimera Tool applies an automatic firmware or modem patch before restoration, with the repair lasting until the next software upgrade.
Not all devices support this feature, and root access may be required, so technicians should always check the official list of supported devices. In most devices IMEI repair can only be only used with a licence, and on some LG models, it takes additional credits.
ChimeraTool's Repair IMEI feature is available for 4,465 models across 85 brands.
