Hi All,

Good news... I am able to solve this NVRAM error i.e. NVRAM WARNING: ERR 0x10
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 :good::good::good:

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

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.

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.
