I have an issue with Fire 7 (2017) and fireOS 184.108.40.206.
The adb authorisation popup does not show up...
FireOS was 220.127.116.11 (from delivery), with this version, when I tried to connect to adb, authorisation popup was working, BUT i never agreed the key.
after that, I updated this tablet to fireos 18.104.22.168 and now ADB authorisation popup do not show anymore...
I tried everything, disable abd, remove authorisation, re-enable adb, reboot device, etc. nothing works.
So i tried with another Fire 7 (2017), brand new, with fireos 22.214.171.124.
I connected it to adb, agreed the key from the popup, everything worked as expected.
Then I updated this tablet to 126.96.36.199 and adb works !
When I tried with another PC, authorisation popup is shown and all works.
So I think there is a bug in fireOS 188.8.131.52 which do not show ABD authorisation popup if no key was authorized before updating to 184.108.40.206..
Does anyone have the same issue ?
Is there any workaround to retreive ABD connection with my first tablet ?
Thank you for your help.
