How to fix WiFi NVRAM WARNING: ERR 0x10
(This post was last modified: 01-30-2016, 04:46 PM by hovatek. )

What you'll need:
1. The phone must be rooted
2. Install ROM toolbox lite on the phone
3. A PC
4. Download and Install HxD Hexeditor on the PC

Follow the steps below.

# See the video tutorial below or @ http://youtu.be/l5WNO7i110M

1. Switch on the WiFi on your phone.
2. Go to settings > about and write out your phone's Wi-Fi MAC Address displayed there. It should look like xx:xx:xx:xx:xx:xx
3. Switch off the WiFi on your phone
4. Launch ROM toolbox lite on your phone and select root browser
5. Navigate to data/nvram/APCFG/APRDEB and copy the file named 'WIFI' from there to the SD Card of your phone's SD card
6. Send the WIFI file to the desktop on your PC
7. Launch HxD-Hexeditor on your PC and click on OPEN or Ctrl+O then select the WIFI file you just sent from your phone
8. Go to the first row in the opened WIFI file then go to column no. 04
9. Insert the value of your actual MAC Address (the one you copied @ step 2) two by two from column 04 to 09 (Ensure that none of the value is ZERO) example: if your MAC address is 00:08:62:92:ee:fa then you'll fill it as:

04 05 06 07 08 09
00 08 62 92 ee fa

10. SAVE this change
11. Close Hexeditor and copy the newly edited WIFI file from your PC to the SD card of your phone (ensure to delete the older WIFI file from SD Card before copying this file).
12. Launch root browser in ROM toolbox lite on your phone and move this file from SD card root to File system root/data/nvram/APCFG/APRDEB
13. Long press the WIFI file then set permission to rwrw (tick first two boxes on row 1 and 2)
13. Turn on your wifi then turn it off again

Your phone's WiFi NVRAM Error should have been resolved. If this issue persists, simply copy the WIFI file from a friend's phone of the same type then repeat the above steps.

If the above exercise fails try this:


After many attempts where the MAC address would change after WIFI start & the NVRAM error reappearing the simple detail I missed was changing the permissions to Read Only.

BTW: Changing the permissions is simple when after you edit the WIFI File as described above using your Hex Editor of choice on your PC, save the file (allow over-write), RIGHT CLICK - select PROPERTIES - look at the bottom of the properties window - select the READ ONLY box & hit APPLY.

As demonstrated above - Copy the edited WIFI file to your SD card or to your phone's internal memory (where you can find it) and replace the WIFI file in the APRDEB  Folder as shown above.
