Select “change or write imei” from the dropdrown menu. So next time when you are able to get Maui Meta tool to recognize your phone, then 1. Here is a Google drive link for it I saw your comment that you are sometimes able to connect. Anyways I have managed to recover on file from my crash system, not sure but hopefully it is the one. I had bookmarked the site but it is lost due to crash. This is a very rare database file which I think I found on either Chinese or Russian site when I fixed my device. Anyways what I remember is that you need correct modem database file to fix IMEI for K4 Note (MT6753 chipset). Since then I too am struggling to get Maui Meta 3G to detect my smartphone. Hi Nik, Unfortunately I had a system crash last week and lost all the working drivers and other important files ðŸ˜¦ unfortunately I didn’t had any backup. I am hoping that i I will be able to fix the “serial no” issue with it. Is the nvram.bin file you have provided is a raw file? When I tried to load it into flash tool, it complained that there is no header for the bin file and the process stopped For everyone: Can someone please share an original nvramp.bin file for Lenovo Vibe K4 Note. What is the difference between nvram.bin file and modemdb and apdb files that comes with stock ROM? I am able to fix my invalid IMEI problem permanently using Maui Meta 3G tool but the serial number is still all zeroes. I have Lenovo Vibe K4 Note powered by Mediatek MT6753 chipset 2. If I do not have a back of nvram.bin, then where can I download it? Does it not come with Stock ROM? If you or anyone can answer them I’ll be very greatul. Hi, great tutorial! Though I have some questions. You have the correct nvram backup, you can give a try and confirm ðŸ˜‰ Thanks. I haven’t found any confirmation of that on the net. AFAIK the only chance to obtain a nvram image backup from mt64xx device is to make a flash tool “readback”, but i don’t know if this is the same image of the one obtained by MTK Droid Tools and if it is (successfully) flashable back again with flash tool.

MTK Droid Tools can’t be used with new 64bit processors (mt67xx). So this procedure is only verified with mt65xx chipsets.

Congratulations ðŸŽŠ!! NVRAM restored & IMEI permanently fixed.

Now connect your phone w/o battery ðŸ”‹.
