Thumbs up [Solved] [WiFi NVRAM WARNING: ERR 0x10]

Updated 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.

Please share here in this thread if you find any difficulties or problems in following these steps.

Wishing all an NVRAM Err Free MMX A110

Just follow these steps and hopefully it should work for your phone also.

Prerequisites:
(i) you have a backup of valid IMEI of your phone (both sim slot).
(ii) you have a rooted phone.
(iii) you have one stable file explorer installed on your phone that can access system files.
(iv) you have nvram folder created and visible in your phone (Ideally there are Three folders + Two files. Folders are named as 'APCFG', 'dm', 'md' and Files are named as 'BackupFlag', 'RestoreFlag')

Step # 1: Download the attached RAR file and extract it to your computer. You will find two files in it.
Step # 2: Copy these two files (extracted) to your SD card
Step # 3: Navigate to system\data\nvram\APCFG\APRDEB (You will find two files here 'WIFI' and 'WIFI_CUSTOM')
Step # 4: Replace both these files with the attached ones.
Step # 5: Reboot your phone and ENJOY

Please let me know if you find it working for you.

Worked perfectly for my MMX A110. God bless and thank you.

DO NOT CHANGE ANY OTHER DATA EXCEPT MENTION BELOW, OR ANY UNHAPPY THING CAN HAPPEN LIKE DEAD PHONE ETC. I AM NOT RESPONSIBLE FOR IT.

Micromax A110 IMEI can be found on the box or under side after removing the cover and battery you can find a sticker attached to the phone which has both IMEI numbers.

1- Rooted MTK 6577/6575 Smartphone
2- Mobile Uncle Tools from Google play store.
3- Install it and goto Engineer Mode
4- Select Engineer mode[MTK]
5- Under Connectivity Tab go to CDS information
6- Select Radio Information
7- Select Phone1 (for the first imei)
8- at the top there is a command line which begins “AT+” just type there “AT +EGMR=1,7,”IMEI_1″ (instead of IMEI_1 put your first imei number)
9- hit send command
10- You will / may get a confirmation that "sent to mSend".
11-Now come back and select “Phone2″
12-at the top there is a command line which begins “AT+” just type there “AT +EGMR=1,10,”IMEI_2″ (instead of IMEI_2 put your second imei number)
13-Then just reboot the phone.
14-Dial ” *#06#” to Check Imei.

Hi, the guide from 1st post doesn't work for me. There is still wifi named NVRAM warning err.... And all this guides are not permanent. After installing new rom (wipe all) you have to restore IMEI and all other once more. Do you know some solution to fix it permanently (as a new phone)?
Thanks for respose.

Link has been removed intentionally because it changes mac address.
