I did check around to see if anyone else had the same issue but couldn’t find it, so apologies if I missed something.
I was following the LineageOS install instructions for using a Windows PC via adb/fastboot and TWRP. After wiping the phone ready for install, I get to step 8, which says about copying the install zip packages onto the SD card.
Since clearing the OS, it appears that I no longer have USB debugging enabled on my phone so the adb devices list comes up blank.
I have attempted with alternatives to get the files onto the SD card but, due to the file system being exFAT (it is a 200GB SanDisk micro SD card that I have had no problems with), the other devices I have are unable to read it.
In looking for other posts, I did find this one that probably would have helped but now my SD card isn’t recognised by my phone. I checked another SD card, which was recognised after rebooting my phone, but it doens’t contain the backup so is pretty useless.
Any suggestions with how to continue with my install would be gratefully received.
I have a backup of an old version of FPOOS that I took prior to wiping the internal storage, but I was unable to update the OS, or any apps via F-Droid, which was my primary reason for migrating to Lineage.
I look forward to any productive responses.
