We are going to explain how to revive dead Huawei model STK-L21

Operation needs to Octoplus Huawei

Open the Octopus interface and select

STK-L21

Open device and connect test points then press on

on/off factory mode

The server will download the files for you automatically and flash the device, it will enter Fastboot mode and it will read device info of the last firmware that was on the device before it died.

But we MUST not let Octopus read info because if you let it read the device information, FastBoot and reboot to boot mode, the device will die again!
