[HowTo][OPO]Fix MTP driver permissions

trainailleur

Florian, this works well. Thank you for the fix.

/a would not umount, giving me the error umount: can't umount /a: Device or resource busy I couldn't see easily what was keeping it busy, so I just tossed umount the -l (lazy) flag, and it worked fine.

I also had to issue a CTRL-D between steps 10 and 11.

After reboot, MTP worked fine.

Thanks again!

Stephen

@trainailleur Good I updated my guide!

Well this was really really easy to do.

I take my hat off to you Florian for taking the time to sort this guide out and write it up.

I followed it and ...yes it is idiot proof!

It worked.

The only change I would make is to insert the word "text" in 7 between favourite and editor

Now my OPO rebooted and mounted automatically

Yippeeeee

After typed adb reboot recovery, I obtain this message:

error: device offline

Known OPO error never resolved

Thanks @Flohack, your HowTo worked perfectly.

Step 1 did not work on my OPO, so I had to put it manually into recovery mode (Powerbutton + volume down for a few seconds (while it is switched of)). Then steps 2 - 12 went smoothly. Thanks for the HowTo!!!

@rocky58: If adb reports "device offline", then it sometimes helps to simply wait for a few seconds or to unplug and plug in again the USB cable. This worked for me.

Okkkkkkkkey... all worked fine. At last I can mount my OPO using my Ubuntu PC.
Thanks @Flohack for the job and also @GT for the suggest.

@flohack helping a user in the UB Welcome & Install Group he thought he have to type all the commands on the phone screen. So maybe is a good idea to add the step Connect the PC or laptop to the phone using a USB cable or something like that.

Thank you for your guide!

flohack

@advocatux OK thanks added a hint

@Flohack please take the Note, I just learned, that you have to install the

[[HowTo] [OPO] Fix MTP driver permissions](link url)

before attemptig to update/upgrade with the ubports-installer , because this is mandatory.
the installer will not be successfull whatsoever before taking care for that solution at the
affected Devices !!

@pet_hh don't leave us hanging! What do we need to install? ^_^

flohack

@pet_hh Hmm this is strange, adb should work, only MTP would be broken. We shall test!

I have a problem with this HowTo:
When i start "abd reboot recovery" i come to the Recovery Screen.
But what next?
Choose one of the options? Which one? When i try to access the phone by "adb shell" the terminal shows "~ # " and not "...@phablet..."
Since there is a warning ( it can damage your system files! ) i want to be sure what to do next:
Choose an option or continue in the terminal?

flohack

@nutzernam Dont choose any options in recovery. Just let it sit there and type adb shell

flohack

@nutzernam And yes there is no phablet user, you are in recovery and are root user. Take care

advocatux

@nutzernam when your phone is on that recovery screen you don't have to select anything there, just use your terminal.

When i try to access the phone by "adb shell" the terminal shows "~ # " and not "...@phablet..."

With your phone connected, type first adb devices in your PC to see if adb recognizes your OPO. That command also starts the needed server if it isn't running already. If it does, follow the instructions carefully. If it doesn't maybe there's a problem with the usb cable, or the usb port you're using, etc

Edit: @Flohack was quicker

nutzernam

@advocatux and @Flohack thank you ! There were no further problems and i can acces my OPO in the filemanager. Now i feel like a highclass-hacker although i have absolutly no clue what i have done to my phone
