correcting nvram wifi errors....
i did what earlier posts said, but everytime i get the same error. smtimes 0x04 , ox10 , 0x12
and here is the way i corrected it.
my wifi chip: MT6628 v1.9 (learned from engineering mode MTK) it has a MTK6589 cpu bytheway.
no mather what you did with the WIFI file you have to correct the permissions after copying them to their folder in nvram.
woking WIFI file permissions for me is:
Location: /data/nvram/APCFG/APRDEB
Permissions: -rw-rw----
UID: 1010 wifi
GID: 9997 nvram
no errors after reboot.
Try this also...

i'am facing a problem with a Lenovo a830 . after re flashing with stock firmware and many custom rom's it says (( Invalid imei ) but the name of the network behind the invalid imei eg : (( invaild IMEI : Vodafone )..... i tried the My uncle mobile method to edit the imei Number And its worked But with two Problems :
1- The network Signal after some hours of working gives no signal and u need to restart the device to get network again >....?????
2- The Imei which u wrote on the My uncle Mobile application is erased if u make a rest or wipe data for the device ...and u should re enter it again ????
Any Help to make that IMEI is fixed on the device as usual >>>>>>??????? pls help

You made my day!
The procedure of post 1 fails also with my NEO N003 V1.1. I have tried your additional hint, found out that "9997 nvram" is not existing, but took "9998 misc" - and it works! WIFI-MAC adress is fixed now (even after several restarts).
Thanks a lot!
For me and my NEO N003 the correct procedure is

Hunh....
Never even realized this bug existed until I used my imported, unlocked, phablet to do a local wifi spectrum scan and saw a local network that I knew didn't actually exist named "VRAM WARNING: Err = 0x10" and decided to do a couple searches and run some tests on the device.
Yes, it's MAC address is randomized every time it reboots... Considering the country I imported it from, I'm not surprised. They're kinda heavy on censorship there. Kinda like it as-is.

The final step
guys, because after reboot the system will change automatically the wifi MAC address, to make permanent the solution of this guide you have just to set permission of the WIFI file (root/data/nvram/APCFC/APRDEB/) in read only (-r--r-----).
It doesn't matter if your MAC have one hex couple with "00", it work anyway.
PS. This NVRAM error seems caused by the permission of writing, that allow system to set this WIFI file (row #4 to #9) with MAC 00:00:00:00:00:00 every time you reboot or upgrade firmware.
hope this can help you

50Updated as on May 04, 2013 sharing working solution
At the first of this post, I would like to give full CREDIT of this solution to 'Nishroy' on whose post I have developed this step-by-step guide. I have used the same on my A110 and sharing the steps that I have followed.
Prerequisites:
On Mobile : i) it must be rooted ii) it must have root file explorer installed (i used 'Total Commander' - you can download it from Play store).
On Computer (Desktop/Laptop) : A stable Hex Editor Application. I used 'HxD - Hexeditor Ver. 1.7.7.0' on my laptop running on Windows 8 64 Bit OS.
Step wise Guide
Step # 1 : Switch on WiFi adapter on your phone.
Step # 2 : Go to 'About Phone' from Settings and note your phone's Wi-Fi MAC Address mentioned there. It should lok like xx:xx:xx:xx:xx:xx (xx = value of Mac Add.)
Step # 3 : Switch off WiFi adapter on your phone
Step # 5 : Launch 'Total Commander' application on your phone and navigate to File system root/data/nvram/APCFG/APRDEB and copy one file named 'WIFI' from there to the SD Card of your phone
Step # 6 : Copy this file i.e. WIFI from your SD card to Desktop on your laptop/desktop
Step # 7 : Launch 'HxD-Hexeditor' on your laptop/desktop and click on OPEN or Ctrl+O and select WIFI file (copied as per Step # 6) from desktop
Step # 8 : Refer to the first raw in the opened file and go to column no. 04
Step # 9 : Insert value of your actual MAC Address (as per Step # 2) in column 04 to 09 (Ensure that none of the value is ZERO) and SAVE this change
Step # 10 : Close Hexeditor and copy changed WIFI file from your desktop to the SD card of your phone. Delete older WIFI file from SD Card before copying this file.
Step # 11 : Once the file is copied to SD card, launch Total Commander application and move this file from SD card root to File system root/data/nvram/APCFG/APRDEB
Step # 12 : Reboot your phone
Voillaaaa! Your phone's WiFi NVRAM Error is gone now. Yes, you solved it.
