Engineering firmware is a modified version of the stock ROM (firmware) that is often used for debugging, testing, and engineering purposes on mobile devices.
While the primary purpose of an Engineering ROM may vary depending on the device and the specific modifications made, one common feature is the ability to perform IMEI repair.
It’s important to note that the use of Engineering ROMs and IMEI repair tools may have legal and regulatory implications, as altering or tampering with IMEI numbers is often restricted or prohibited in many countries. It’s recommended to ensure compliance with local laws and regulations before engaging in any IMEI repair activities.
