    for those of u wondering why cant u enter engeneering mode in ur android , thats is probably because of ur custom rom, especially for cyanogenmod users, im using cm12 rom and i cant enter enginerrmode either but when is switch back to my stock rom, it works fine. and its really a pain in the ass to switch back to ur stock rom just to backup ur imei and restoring it in a custom rom with mtk tools, i just hope this is the answer to my problem

    i can go engineermode but the process to fix imei error is not working =/
    if u cant go to engineermode by using code, try download MOBILEUNCLE then explore how to use it and go to engineermode without code ;)
    u can download it on playstore ..

    The tool is simple but inflexible in use, do not select the desired IMEI

      reboot and entering RECOVERY mode, in my case i'm use TWRP. Just download that is file then copy into your SD CARD, 

      Install zip via TWRP – reboot

      good luck
