How to solve the problem of “Invalid IMEI” – By Marshall0544

When IMEI numbers have lost  after hard reset (full flash) on Phone MTK65XX -  It will appear  “INVALID IMEI” on the screen of your Zopo smartphone.

Here is the solution:
Smartphone must be rooted

  • Backup file containing IMEI codes MP0B_001
  • The file containing the IMEI codes (MP0B_001) in Android systems with processor MTK65XX, is in the following location: /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
  • Backup and copy it to the Desktop with Windows 2000/XP/7
  • Place it in a folder created called IMEI in C:\Documentes and Settings\User\ and insert the files imei.exe and MP0B_001.
  • Now open a cmd window by typing start -> run -> cmd -> chdir C: \ -> chdir C: \ IMEI
  • Inside the cmd window, type: imei.exe[space][n ° IMEI1][space][n ° IMEI2]  Example: imei.exe 123456789000 123456789000
  • This will create a new file called MP0B_001_NEW

Copy the file MP0B_001_NEW inside Android Smartphone renaming MP0B_001 and overwrite the existing file in  /data/nvram/md/NVRAM/NVD_IMEI/
Restart your zopo smartphone.
Install the file zopoimei_zopomobileshop.apk to change IMEI numbers.

    Ma i numeri del nuovo IMEI da immettere dove li dovrei prendere? Li devo inventare o li immette l’applicazione automaticamente?

      Per il primo numero cerca di scrivere quello originale scritto internamente allo smartphone, dietro la batteria. Per il secondo, usa l’applicazione dedicata scaricabile dal Blog.Tieni presente che se usi un SOLO IMEI per due SIM, una bloccherà l’altra. Un IMEI > una SIM.

    Hello Jessica Tang,
    only you can help me !!!

    I have a zopo zp950 + 4gb that some days is crazy, install or upgrade apk but the application is restarted not find them anymore. Continuous crash of apk. I tried to flash the firmware with SP flashtool the procedure comes to an end, it comes out the green circle, but when I restart the device everything remains as before.

    What should I do? Should I do a hard reset? How you doing?

    My dear zopo not want to miss !!! Help me please.

    Thanks you are very kind.
