Did you delete the existing mpb001 file > replace it with the newly created one > wipe your phone in recovery mode then reboot?

(21-07-2014, 11:43 AM)user005 Ok
If you get a working phone of the same model then an NVRAM backup & restore using MTK Droid tools is all you need. If you can't get a working phone of the same model then you need to create an MB0B_001 file > delete the exisiting one > replace with new one then restart your phone or wipe data / factory reset. Were you able to successfully create the MB0B_001 file?
