SC20 - Wi-Fi Issue

Hello community,

I am using a SC20 SMART-EVB_1.3 Kit.
Recently I’ve flashed a new boot image (boot.img) with slightly adjusted permissions at
My issue is: Wi-Fi service (WLAN) stucks in the OFF state when I am trying to enable it… The MAC address that is shown on the WLAN is 02:00:00:00:00:00, thus I suppose there is a problem. All the other services, like Bluetooth, LTE, et cetera - are working.

Does anyone have an idea, what could go wrong after flashing and how to fix that issue?


It sound like you wiped the NV memory when you flashed. I have no idea what the SC20 is based on, (i.e. what’s inside). But, if it is a Qualcomm chipset, you should be able to use QXDM (or Quacktel’s own tools) to reset/replace the NV items. That said, there should be other backup partitions of the NV items.

Please contact the support, as I’m just an innocent member.

The bootimage don’t match with system.img.

The phenomenon is that when you turn on the wifi button, it automatically turn off.

The wlan.ko is in system.img. So when we use fastboot to flash bootimage.

The signature of the wlan.ko will no be able to installed.

Then the wifi will be abnormal operation.

Do you mean, that I have to compile and flash system.img along with boot.img ?

do a test and tell result.

Hi Jax,

You were right. The issue was due to system,img and boot.img mismatch.
After flashing SC20 with both images, the problem was resolved, and Wi-Fi service works now,
Many thanks!
