[Q] Formatted NVRAM using SP Flash Tool, what should I do?

Phone: Micromax A89 Ninja
Processor: MTK6577
Hello Gys Sir, this is my first post as I could no longer find any
solution on the internet. Hoping some experts could help
I accidentally formatted the NVRAM of my phone using SP Flash
Tool. Because at the time of formatting I didn't know what NVRAM is.

[Problems]
1. Now
my IMEI's are lost. Although it is still possible to restore them using
some methods(I used Mtk Engineering Mode, Mobile uncle tools, Maui Meta 3G).

2. A NVRAM Error Warning msg with Wifi signal created in wifi adapter setting.

3. If I Wipe deta of my device or re flah Stock ROM or any Custom Rom many Games and apps Doesn't run with a message Unfortunately 'apps/games' has been stopped. (like Root Explorer v3.1.5)

But none of the methods I have found were permanent. A simple wipe/data factory reset from CWM
Recovery removes it instantly. Is there any way I could restore the NVRAM, or at least make the restoration methods
permanent? And get rid of Wifi NVRAM Error Warning msg. Also can smoothly run all apps and games. Please help me I'm in big trouble...
