[Q] Switching between USB and Mass storage modes

Back in the days of my SGS1, we could switch between MTP and mass storage mode using the following commands in a terminal emulator session :
To enable MTP : setprop persist.sys.usb.config mtp
To enable mass storage : setprop persist.sys.usb.config mass_storage,adb
Will these commands still work on a rooted SGS3 ?
Current config :
Phone model : i474m
Carrier : Bell
ROM : Stock LH1 + root
CWM : not yet installed (no Nandroid... hence why I'm not willing to try for myself at the moment)

no one?

USB Diag Mode

Has anyone been able to access the USB diagnostics on the 10? Usually it's ##3424## but it either changed or it's blocked. I tried multiple ROMs with same results.

Tried it. This gives you the functions test, not USB diagnostics.

Oh cool, that was just in memory lol. Can you use an app for diagnostic, not sure what you want to test. The only other one is *#*#4636#*#* I think.

I don't think an app will work, thanks though. I'm trying to unlock the Canadian LTE bands. I just need to put the phone in USB diagnostics mode so I can use the modem tools on it.

Has anyone figured out how to enable DM mode on the US Unlocked model? On Sprint and Verizon ##3424# works just fine.

Na that was for debug mode..
setprop sys.usb.config rndis,diag,adb worked for me

Any way to enter diag mode without root? Entering ####8899# will make "Lenovo HS-USB Diagnostics" show in the device manager. I think it's necessary to have the "Qualcomm HS-USB Android DIAG" in some cases so I'm looking for a method to enable it.

Hello did you found a fix? I want to unlock b5 and b28 on mine.
