The frustrating part about this is that it's getting <i>more</i> difficult to flash ROMs onto most phones, not easier. For instance, all Samsung Galaxy flagships since the S6 have a locked bootloader. If you have the US-based Snapdragon models, it's nearly impossible to unlock them and load custom ROMs. And if you somehow do, Samsung caps your battery at 80% or so.<p>There are notable exceptions. The OnePlus phones are easy to flash, as are Sony Experia models. But for the average person just looking to get a few more years out of their device, the OEMs have made it very clear how much they resent you keeping your phone beyond the two year mark.
