My Android phone came with a tiny amount of memory and my phone company filled most of that with useless, undeletable apps. I finally had it and unlocked my phone, installing a custom firmware. It took me back to the days when I did it on my PSP. It’s still the same environment…bad instructions in forums assuming you know way more arbitrary details than you actually do. (What? You weren’t born knowing what BackSideUpdater is? It’s so obvious!) All files are obtained via questionable links in forums. The best instructions I found were on some kid’s youtube video. Anyway, it’s done and I actually have some space to install some apps now. We’ll see how this goes.
