Question

I am new to Android development and bought a cheap Huawei Sonic (U8650 apparently) so I could test my first attempts at making an app on an actual device.

However, whenever I try to use ‘adb logcat’ or ‘adb shell’ then ‘logcat’ on the device I get:

Unable to open log device '/dev/log/main': No such file or directory

I have already enabled Usb debugging in Settings -> Developer.

I just don’t know enough about Android to know if this is something I can even fix.

I have found two other questions with similar problems:

/dev/log/main not found

??-?? ??:??:??.???: INFO/<unknown>(<unknown>): Unable to open log device '/dev/log/main': No such file or directory

…but they both turned out to be using some kind of non standard kernel that had logging disabled. Mine is a stock phone out of the box.

It’s a very cheap but snappy Android 2.3 phone, so hopefully it wasn’t a total waste of money.

Any help would be greatly appreciated.

Answer 1

I have actually found an answer for this finally!

I was having another aimless look to see if anything had been updated about this anywhere and came across a post on xda-developers about a slightly different Huawei device with the same problem.

It actually worked. I have complete logcat logging on my Huawei Sonic (U8650) now.

Three cheers for not giving up.

Solution, copied from the xda (in case it is removed etc):

There is a hidden service-menu where you can set loggin up. The
service-menu is started by "dialing" this phone number:

*#*#2846579#*#*
