I’m installing eOS on my OnePlus 7T for the first time. Everything was going well until I sideloaded the eOS file. Instructions said that it may pause at 47% which it did but then a minute later I get “adb: failed to read command: No error”. What is this and what should I do now? Please help!!
The finish at 47% is quite usual, not just a pause, 47% positively indicates “job done”. The “No error” to my instinct is that the device is ok. When I search that error I see no satisfactory general answers. It looks like it can frequently be a compatibility issue with Windows, perhaps involving drivers, perhaps a “timing issue”, even cables or ports. Also seen in Linux, and attributed to “use a different platform-tools version” for this setup. Some even report that the sideload had actually worked despite the error!
Did you check what happens if you assume the flash was successful?
… and, Edit, did anything change on the device screen? To reexplain my very first comment, the 47% is the successful end of that bit, has the PC failed to deliver the next bit?
I went back to the main screen and selected “Reboot System now” and it booted to the eOS setup screen. So I think I’m good now! Thank you for everyone’s quick replies!
