Can we change default USB configuration to MTP mode by editing build prop "persist_sys.usb.config" ? Which value to be used ? Or else any option.

When the host mode drivers were being released for the Tab there was some mention of being able to turn on host mode without a OTG cable being required (with it's special resistor)
I cannot seen to find an option to force host mode in the few roms I've tried.
Is there maybe a command from the terminal I can use to trick it to turn on?
Hi, on my Nokia 4.2 phone I've enabled adb debug mode, but when I set USB transfer mode to mtp, the adb connection gets disabled. Is there a way to have both features enabled?
Thank you
I can't pick any option when I connect the phone to the computer, they all are greyed out. The only way to transfer files from my phone to my PC is through TWRP or changing the default USB option through developer settings.
Can someone help?
Can you attach screenshots?

This happened with me on my phone's stock image. All the usb options were greyed out. I tended to look for solutions, but couldn't find anything relevant. Then, with a later update, it got fixed. However, now I'm using a custom rom(Resurrection Remix), so there are no issues with USB atm.
I would suggest you to install a suitable and stable custom rom(Lineage OS, is the best) on your device. It might help.
If you are on Lineage (You don't say) just set the USB option to always transfer in developer settings, Plus make sure USB debugging mode is turned off.
Hello, I have a Sony X Xperia Performance. Stock firmware 41.3.A.2.149 has been flashed. Full wipe was also done with TWRP 3.6.0_9-0_dora.img. I have tested several ROMs: ,,lineage-18.1-20210802-UNOFFICIAL-dora.zip" and ,,crDroidAndroid-9.0-20201123-dora-v5.12.zip" from XDA.
Both ROMs doesn´t allow USB adjustment for file transfer (MTP) under "connected devices" in the settings. But if I go into developer options, enable USB debugging and go into default USB configuration, then I can turn it on.
What is the reason? What am I doing wrong? Thank you!

Hi ! I post again because when I connect usb key mtp works and if I connect to my mac and go to settings usb parameters and choose transfert files/Android auto that work but never had notification pop-up for choose it
USB is a master/slave protocol. When you plug in an otg cable, your phone's USB controller switches into host mode. Your computer's USB is always in host mode. So your effectively trying to get two master devices to communicate which USB does not support.
