Is anyone else having issues using adb.exe to sideload apk and files onto the Pico Neo 3 Pro? this was working in the past and I was wondering if its just me?

I'm also not seeing the usb messages pop up on my laptop when i connect the hmd - seems its only accepting charge rather than file transfer - even though i have both USB set to developer mode and the USB port on file transfer.

On top of the HMD im seeing the light flash between white/green (charging?) and blue

closed with the note: Solved by doing reset as stated in answers

Hi,
Try to restart the device or computer and enable the USB Debugging again
Then run adb Devices to check whether the device is displayed.
Or try another USB cable.

Tried all those options :( I have another Pico Neo 3 Pro that I'll also try, I was just wondering if it was me or something more wide spread.

Maybe try a different USB port or computer

i have tried multiple USB and multiple computers. I've now also tried multiple Pico Neo 3 Pro. Each time im getting the same result - i.e no connection to the HMD for file transfer via direct (like a external drive) or via adb.exe . Previously, autoplay would popup on the laptop when i connected the cable - that no longer occurs.

FYI the HMD does charge from the various cables ive used, and the cable does work for debug on my android phone and autoplay settings appear as well.

right - so the only way i got the adb to work was to do a reset. After the reset the adb worked with no issues and the charge light was not flashing backwards and forwards between white and blue when i attached the USB to the HMD and PC. To me this proves that there is an issue with the firmware upgrades that have happened since the initial HMD went out. I can also see the hmd appearing as a drive on my windows laptop

I did find another way to connect on the forum - you can use adb via wifi - https://devanswers.pico-interactive.com/index.php?qa=1478&qa_1=root-mode-password-additional-develop-%26-debug-settings

Unfortunately, following the information on the post, plus other posts regarding using adb over wifi, (eg first connect a known device that works for debug using a usb cable) i still get the following error:

adb tcpip 5555
adb connect 192.168.xxx.xxx:5555
cannot connect to 192.168.xxx.xxx:5555: No connection could be made because the target machine actively refused it. (10061)

I haven't had this problem with my device. or maybe you could find out if there is an Android Assistant on PC, such as 360 Mobile Assistant.
What connection problems might the android assistant suggest or offer to fix.

the only way i recovered access was to do a reset and then update the HMD. After that I got debug back. EDIT: I found the issue - i'd set in the developer options "Act as host" or some such setting - this was the thing that was blocking the access to the HMD
