I wanted to share some solutions that worked for me to some different technical problems. Hopefully someone finds them helpful.
Fixing Chrome OS
For some reason I have not yet determined, my Chromebook (an ASUS C300S) came up with an error message telling me that Chrome OS had an error. Following the instructions given by Google, I created a Chrome OS Recovery program on a USB drive. However, when I inserted this into my Chromebook, I received the error message that Chrome OS was not detected on the USB drive. I tried this with 2 different USB drives and got the same result.
At this point, I am told to contact tech support. They ask me to find the error message and tell me to turn the Chromebook on and off 10-15 times. On the ninth cycle, Chrome OS started normally.
Fixing the USB Drives
After installing the Chrome OS Recovery program on my 2 USB drives, Windows wanted to reformat them, which I did. However, these 7.5 GB USB drives then had only 17 MB of space.
I followed the instructions in the following video and it solved the problem:
It took some effort, since I had many partitions to delete. Furthermore, I ran into an error when trying to delete certain partitions: “Cannot delete a protected partition without the force protected parameter set.” To fix this problem, I had to type “delete partition override” (H/T to TechJourney).
Getting rid of “Activate Service” Notification on Android
I have an LG G4 that I use exclusively with wifi and it brought up an annoying notification that I could not get rid of. Most forums said you could simply hold down on the notification and the “App Info” option would eventually appear, allowing you to force stop the app. This, unfortunately, didn’t happen for me. Other options required having root access to your Android system, and this was more effort than I wanted to put in.
A quick fix that worked for this particular problem was putting the phone into airplane mode and restarting it (it actually took a couple of restarts to work). But in airplane mode, the phone will not search for a cellular signal and will ignore the fact that your phone isn’t activated.
