Manual Steps to try if SuperPatcher or FCChooser doesnt work

1. Make a new folder and name it something simple like SP

2. Download these files: Download dumldore and unzip into folder - https://github.com/jezzab/DUMLdore/releases/download/v3.20/DUMLdoreV3.zip Download adb files: - https://github.com/brett8883/Super-Tools/raw/master/TOOLS/adb.exe - https://github.com/brett8883/Super-Tools/raw/master/TOOLS/AdbWinUsbApi.dll - https://github.com/brett8883/Super-Tools/raw/master/TOOLS/AdbWinApi.dll Download firmware file - https://github.com/brett8883/Super-Firmware_Cache Download dummy_verify.sh - https://github.com/o-gs/DJI_FC_Patcher/raw/master/dummy_verify.sh

3. Copy all into same folder 4. Connect aircraft to the computer and power it on. 5. Open DumlDore. Click “Enable ADB” in DUMLdore and then close DUMLdore 6. From a command prompt, open the same folder as your files (Adb.exe, the firmware file, etc) 7. Run these commands from cmd prompt

adb shell mount -o remount,rw /vendor adb shell mkdir /vendor/bin adb push dummy_verify.sh /vendor/bin/

8. Now, different commands depending on aircraft.

## If Mavic/Spark, use these commands adb shell cd /vendor/bin chown root:root dummy_verify.sh chmod 755 dummy_verify.sh cp /sbin/dji_verify /vendor/bin/original_dji_verify_copy sync cd /

## If P4 series, I2 run these commands adb shell cd /vendor/bin chown root:root dummy_verify.sh chmod 755 dummy_verify.sh cp /system/bin/dji_verify /vendor/bin/original_dji_verify_copy sync cd /

9. Power off the aircraft. Keep it plugged into the PC. Power it back on. 10. Open DumlDore. Click “Enable ADB” in DUMLdore and then close DUMLdore 11. From a command prompt, open the same folder as your files (Adb.exe, the firmware file, etc). 12. Open a cmd prompt 13. Now, different commands depending on aircraft.

## If Mavic/Spark, use this command: adb shell mount -o bind /vendor/bin/dummy_verify.sh /sbin/dji_verify

## If P4 series, I2 run this command: adb shell mount -o bind /vendor/bin/dummy_verify.sh /system/bin/dji_verify

14 .Keep the aircraft powered on and plugged in!

15. Now, you can flash your aircraft. Open dumldore. Press load firmware, navigate to the firmware file you downloaded earlier. Press flash firmware. Let it do its magic.

Don't power off aircraft during firmware flash.
