I just want to make sure that this is related the ONEplus 5 and not OnePlus5T.
The aduio issue is that there is no sound output when I play any audio file. The same issue exists during phone calls. Also notifications do not sound when they occur because o the same issue.
The second issue is the hardware Home button on OnePlus 5 does not work at all. Only the “Back” and “Recent” buttons work.
I tried installing all available released versions of the /e/ rom for OnePlus 5 but I did not have any luck.
I followed the steps and formatted Data partition and I entered “Yes” then flashed the rom but these two issues have been persistent in the past 4 or 5 releases of the rom
it sounds, that you have an firmware issue. Which OS was on your device BEFORE flashing eOS ? If it was eOS (you have written about update) so I think raising an issue is the best, as Manoj has written.
otherwise the best way is always flashing first the same stock android version as eOS to have the right firmware.
But I am confused about wheather I should flash Lineage OS first then flash eOS on top of it because in link above and the picture attached, the instructions say that the phone must be on Firmware 5.1.4 BUT THEN down below it lists the recommended firmware packages for Lineage 15.1 and Lineage 16.0.
This is where I get confused. IF the eOS itself is Nougat the why Lineage 15.1 firmware and Lineage 16.0 firmware are being recommended.
Thank you @harvey186
I have the latest Nougat firmware ( OnePlus 5 OxygenOS 4.5.15 Firmware+Radio)
I can try and flash it at point 4 and see what happens. Unless you are saying that there is a whole different process to go back to Nougat?
Going back to nougat is not working on all phones. Best way is always to flash first stock android 7 (firmware) and than eOS. But for example o Samsung you can’t go back to nougat becuase of different boot loader.
I flashed OnePlus 5 OxygenOS 4.5.15 Firmware+Radio and then flashed eOS and now the home button and the sound work. Thanks!
I have one question for my own understanding and learning, I flashed the latest eOS, the Phone information in “Settings” shows that the last Android Security Patch is from February 5, 2020 but Android Version is 7.1.2. How is this possible? I mean Android 7.1.2 is no longer being supported so how is it showing that the security patch date is from February 2020?
Can Android Security Patches be downloaded and flashed separately regardless of which Android Version is running?
