If a remote or app update is initiated, the camera will reboot due to the failure of the update. The firmware update should not proceed again for some time, or at all.

When a firmware update is initiated, due to a bootloader bug, we intercept the update process and flash it manually. This should now result in a successful update, if it doesn't, please restore the unit's firmware manually using demo_wcv3.bin on the micro sd card.

```/system/bin/app_init.sh``` loads the stock system software

During execution of ```run_mmc.sh```, if ```DISABLE_FW_UPGRADE``` is set to ```false``` we intercept the stock firmware upgrade process. We run ```inotifyd``` at startup, to observe the /tmp/Upgrade directory.
|
||||
|
||||
Normally, ```iCamera``` downloads the firmware upgrade tar to ```/tmp/img```, renames it to ```/tmp/Upgrade.tar```, then extracts it to ```/tmp/Upgrade```
|
||||
|
||||
```inotifyd``` monitors ```/tmp/Upgrade``` for the file ```upgraderun.sh```, this is the script responsible for flashing the firmware files to their respective partitions. Once the file appears, ```inotifyd``` calls the script ```/opt/wz_mini/usr/bin/watch_up.sh``` which will rename the file to ```upgraderun.old``` and kill the script if ```iCamera``` was fast enough to launch it before we renamed it.
|
||||
|
||||
```watch_up.sh``` will then proceed to flash the main partitions directly, instead of doing what the stock script does, which is to flash the images to backup partitions, and then let the bootloader flash the main partitions upon reboot, since this process is currently broken when using the loading the kernel from the micro sd card, which we do.
|
||||
|
||||
|
||||
Once the partitions have been flashed, we reboot the camera.
