# Alta X Recovery Instructions

***Context:** Use this process when an Alta X flight controller profile gets deleted and the aircraft needs to be reprogrammed with the Alta X OEM profile, firmware, and parameters. A symptom of this usually is Blue boom LED's and loud motor beeping.*

Before proceeding with the steps below, ensure you have downloaded the required files:

1. Download the latest Alta X QGC Version:
   1. Go to the designated source and download the latest version of [Alta X QGC ](https://freeflysystems.com/support/alta-x-support)onto your laptop or desktop.
2. Prepare the Drone for Parameter Loading:
   1. Without batteries plugged in, connect your Alta X to the computer using a USB-C cable via the expansion port and [use MSC mode to connect.](https://freefly.gitbook.io/freefly-public/products/alta-x/untitled-7#downloading-datalogs)
   2. Once connected, the drone should appear on your computer's desktop as a hard drive.
3. Download any existing Tempcal and Parameter Alta X Files from the aircraft:
   1. From your drone's hard drive in the computer, locate the Tempcal file (e.g., 491625-tempcal.params) and the AltaX.Params file
   2. Download both these files to your desktop for easy access during the configuration process.
4. Update Firmware with Alta X Firmware:
   1. NOTE: Alta X and Alta X Blue get different parameters. Ensure you download the correct firmware for your hardware version
      1. Follow the [instructions provided in the Wiki ](https://freefly.gitbook.io/freefly-public/products/alta-x/untitled-4#updating-firmware)to update your drone's firmware. 
         1. Standard Alta X firmware as applicable
         2. Blue Alta X firmware as applicable
      2. Once the firmware update is complete, reboot the drone before proceeding.
5. Reset Alta X Parameters using the guide in [Aircraft Setup](/products/products/alta-x/untitled-7.md#loading-default-parameters)
6. Load Tempcal File (e.g., 491625-tempcal.params):
   1. Access the parameter settings on your drone control software once more.
   2. Use the tool button to load the Tempcal file (e.g., 491625-tempcal.params) to your drone.
   3. After loading, reboot the aircraft to apply the Tempcal file settings.
7. Recalibrate All Sensors:
   1. Now that all files have been uploaded, it's essential to recalibrate all sensors for accuracy.
   2. Follow the [Sensor Calibration Procedures ](https://freefly.gitbook.io/freefly-public/products/alta-x/untitled-7#sensor-calibration)provided in your drone's manual or the QGroundControl software.
   3. Always remember to select "No Rotation" for your External Compass Orientation.
8. Final Reboot:
   1. After recalibrating the sensors, perform a final reboot of the aircraft to ensure all changes take effect.

Your Alta X should now be configured back to normal with the updated parameters and firmware. Always double-check the settings and ensure the calibration process is done correctly for safe and optimal flight performance.
