IMEI Download: Select "IMEI Download" from the menu, enter your 15-digit IMEIs, and click "Write to Target." 4. Why did the IMEI disappear? Understanding the cause helps prevent future occurrences:
Formatting during Flash: Selecting "Format All + Download" in SP Flash Tool erases the NVRAM partition where IMEI data lives.
Corrupt NVRAM: Frequent crashing or improper shutdowns can corrupt the data partition.
Software Mismatch: Installing a ROM intended for a different variant of the MT6580. 💡 Important Legal & Safety Warning
Legal Identity: It is illegal in many countries to change an IMEI to a number that does not belong to the original device. Always use the original IMEI found on the phone's box or under the battery.
Backup First: Before attempting any "Write" commands, try to back up your current NVRAM/Firmware using SP Flash Tool.
Does your device show "AT command is failed" when you try the dialer method, or is it not responding to the code at all?
