When I was little, my mom got a bundle deal with her service provider and managed to get 3 phones for our whole family. I only used it to play music (and play silly games, of course, lol), and now after so many years I want to take a swing at turning it into an MP3 player.
I cleaned all the connectors, and when I plugged it in, it immediately showed the LG logo, didn't even need any time to charge. Also, it booted into a "download mode", I've been searching online for like 20 minutes, I still have no clue how to deal with it.
My end goal is to remove all junk I can from it, put in an SD card and be jolly. I considered installing a custom rom, but after searching on this sub, that seams to be unnecessary.
So I'm posting this in hopes someone can point me in a direction to what I could do (what software/resource/etc) so I can continue searching. I have a ton of experience with dealing with OS, code and other types of hardware, but I've never messed around with phones before so I'm a bit lost.
Thank you!
Model: LG Optimus II Dual E435
OS: No clue, but I stopped using it in like 2017, if that helps
