usb file transfer does not work #1875

Open rogergithubbing opened 3 years ago

rogergithubbing commented 3 years ago

Hello, I'm using the latest version, but I cannot set the usb to file transfer because all the options are greyed out If I set the usb debug to on, they seem to enable, but when I click on the "file transfer" radiobutton, it automatically deselects itself.

The bluetooth is also not working.

My tablet has these specifications: Allwinner A50 (Cortex A7 4 cores 1,2 GHz) 1 GB RAM 16 GB ROM screen IPS 8" 1280x800 came with Android 8.1 Go

Thanks !

Which variant of GSI are you using? You can try the VNDK variant as it comes with more legacy support towards Android 8.

Could you explain your option in detail ? I don't know which file to choose: What I know so far is that the maximum size for the system file should not be greater than the partition's size, that is 1207959552 bytes, and I was looking for a version , greater than android 8 if possible. If not, which file from which version should I choose and why ? I've been told that the only files that can work with that tablet are the ones with "aonly", because those with "ab" or others will not work.

@rogergithubbing you're correct, only aonly variant works, ignore what @haruki-taka8 said

As for your question, uh that's a tough one. Maybe doing setprop persist.sys.usb.config mtp,adb could help? But my recommendation would be to transfer files through adb

I don't understand the question about GSI; I've tried to flash the latest aosp v11 and 10 versions. And about the "VNDK variant", what is that and how can I obtain it ? I Should then flash only Android 8 versions and not try to upgrade the tablet ?

Merci Pierre ! I'll try that; But why are you recommending to transfer files trough adb instead of the "normal" usb transfer ?

Tried, but didn't work: The same behaviour happens: When I click on the "file transfer" it immediately turns back to usb charging"... no worries, I'll do the transfers by putting in an sd card xd
