I have a Samsung phone with Android 4.2.2. I've already tried various solutions found here and here on internet (Stackexchange, reddit, etc.) to enable USB Mass Storage, but none of them worked.
Thus, is there a rooted version of Android (4 or 5) that I could install on my phone, for which
USB Mass Storage would become the default automatic mode when plugging my phone to computer with USB ? i.e. without having to launch a specific app that has to remount MTP as UMS
NB: this is not a duplicate of the many "how to enable UMS" questions, it's slightly different.
