Just wanted to clean up and update my old smartphone (Huawei Y300). Accidentally deleted the home screen and system.ui and can no longer open apps. TRWP (2.5.x) is too old to flash a new image. Need TRWP 2.6.3.3, but it is impossible to update it from within TRWP. Such a crap.

Inherited a massive code base today... All JS is still being accessed via global scope... what are modules & modular design even... SOLID and DRY are things that clearly never crossed the devs mind during inception of this beast... and to top it all off all there is a weird BEM / SCSS style going on that somehow manages to confuse the IDE... thus all style helper utilities in the IDE are useless...
