Hello, I’m trying to install e/OS on OnePlus 8 pro. I did follow the instuctions on the Murena site completely, but I still get an error message while connecting to the phone:
Error on step: device-detection
Cannot execute command connect adb
The device is not connected Failed to connect: Cannot connect ADB Failed to open USB device: Failed to execute ‘open’ on ‘USBDevice’: Access denied.
Proposal: Check connection and that no other program is using the phone and retry.
Has anyone had this problem already and knows how to solve it? Thanks for your help!
Hi, thanks for you reply. I did manage to come all the way to connection part. The phone is shown for the connection as OnePlus 8 Pro, but when I choose the phone and click Connect, the error massage appears
I menaged to connect the phone to my laptop through Android studio. I’m not shure how to install e/OS form there manualy though. Like you wrote it is obviously some problem with the permissions I don’t know how to solve. I’m not very famialiar with Ubuntu also so I think this procedure may be exceeding my capabilities. I am after all 65 y old
Hello, I’m back for some help. I’ve made some progress. It was the most stupid thing I did wrong in the step of connecting the phone. While typing on my laptop the phone’s screen has locked and that was obviously blocking the conection. I gues this should be added to the instructions.
With the screen beeing unlocked software downloaded but after the restart of the phone in bootloader mode after trying to connect the phone to a computer a new connection error has appeared. Is this problem maybe familiar to you:
Error on step: connect-bootloader
Cannot execute command connect bootloader
The device is not connected Failed to connect: Cannot connect to bootloader after 3 attempts. The device may not be in bootloader mode yet. Please ensure the device is in bootloader/fastboot mode and try again. Error: Failed to request USB device: Failed to execute ‘requestDevice’ on ‘USB’: Must be handling a user gesture to show a permission request.
Proposal: Check connection and that no other program is using the phone and retry.
Right after the ROM was copied to the phone, it rebooted in a bootloader mode by itself. Am I supposed to hold Volume Up + Volume Down + Power after the phone automatically shuts down and restarts?
I’m not sure what am I supposed to do with this instructions:
f still using Ubuntu the recommendation in Post #7 is only two commands to copy and paste to your terminal.
OK my comment to use button press is unnecessary as you are confident that the phone is already in
In the intro did the instructions inform you how unlocking was to be handled? Edit reported unlocked as I wrote.
You are wise to resist commands just pasted by a stranger, originally I linked the Android page explaining why this might be necessary. Edit, It may help to avoid permissions errors.
However eosinstaller should be complete. If it is incompetent, I think best to use manual install.
Thanks for your advice. I did menage to unlock the phone (DEVICE STATE - unlocked) but still get the error while connecting:
Error on step: connect-bootloader
Cannot execute command connect bootloader
The device is not connected Failed to connect: Cannot connect to bootloader after 3 attempts. The device may not be in bootloader mode yet. Please ensure the device is in bootloader/fastboot mode and try again. Error: Failed to request USB device: Failed to execute ‘requestDevice’ on ‘USB’: Must be handling a user gesture to show a permission request.
Proposal: Check connection and that no other program is using the phone and retry.
Good you made the first steps from manual install. You were able to access Fastboot mode by issuing that fastboot command successfully in a way that eosinstaller cannot do (it would seem from your report).
As you read more on the install page it will begin to make more sense. It is ok if this learning process takes some time.
