I did the changes you advised still the firmware update fails due to USB issue. I managed to update the herelink using the product key and all seem to run perfectly. Do I need to do the firmware update? Is it safe to fly with UAV without firmware update? ---

The air unit must be updated by flasher unless its firmware is newer than certain version. Otherwise it won’t pair with controller. For controller unit, you don’t necessarily need flasher if the system updater inside works perfectly. ---

Hi Alvin, The herelink firmware flash always fails due to usb issue! The update I referred to is the one made using wifi not the USB one. The airlink couldn’t be updated since the USB failure still there. I tried using multiple computers with different OS but no success. I can say the product is too complicated to setup and that’s a wrong commercial approach. It’s a GCS that should work out of the box and should require minimum effort to setup or even update but currently no one exactly know how to solve the problem even when I shared what messages I got in the terminal. ---

I agree i bought this product 3 weeks ago & I still cannot fly my drone because I can’t get past these updates. A product that cost this much should not be this difficult… Very dissapponted! I’m paying a computer tech an extra $200 just to come out & do the driver install & complete the update that’s on top of the $700 that I’ve already paid for the Herelink ---

Unfortunately we can’t test all possible issues and we relies people to report what they have encountered. Then we solve and share the solution found. Ordinarily it was easy as plug and update. Such complexity is not a designed feature. We have noticed the problem and no longer using USB to update in future. Newer batches don’t need the USB update process. ---

And what should we do with our herelink now? Buy another and throw this away? ---

Please try again flashing the AIRUNIT via USB on a Windows computer. But first install the Google Driver manually as follows: > [@Herelink new system update](https://discuss.cubepilot.org/t/herelink-new-system-update/7220/7): > > Get the driver from here: Get the freeware Tool “DriverStoreManager”. You will find it via Google. Install the driver by using this tool. Not entirely sure but from your screenshot I would assume that the missing driver is the problem. You may give it a try. ---

Hi seven, I also believe It’s a missing driver but I did installed the driver and went to computer management and picked Optimus and updated the devise using the USB driver file but it didn’t accept it. Maybe it needs special way to work with these drivers ---

Hm. Did you install exactly this driver?: > **[Get the Google USB Driver  |  Android Developers](https://developer.android.com/studio/run/win-usb)** > > The Google USB Driver is required for Windows if you want to perform adb debugging with Google devices. I had to do it manually as Windows always said the driver was up to date, but it was not the correct one. I used the freeware tool „DriverStoreManager“ for driver installation. Immediately worked then. I understand that you managed to update the ground unit via WiFi. So you only need to update the air unit, right? ---

Sorry. „DriverStoreExplorer“ (not …Manager) ![image](https://discuss.cubepilot.org/uploads/default/original/2X/e/e47aa554cfde3b077a6a1b997282155c24b9e7fc.jpeg) ---

Hi sven, You are the only one who gave me a logical answer so far I really appreciate your reply. Yes the the Herelink was updated using the product key through wifi but airlink still not flashed. I will try your method and update you ASAP. So I just use the driver manager explorer to install the driver and that should work right? ---

By the way Sven, Is need to calibrate “Radio” in QGC or herelink joystick calibration is enough? [Next page](https://discuss.cubepilot.org/t/herelink-fail-to-update/7796.md?page=2)
