I'm looking to buy my first e-reader. I plan to buy something used off eBay, like I do when I need a new cellphone. When I get a new phone, the first thing I do is unlock the bootloader and load a custom ROM on it. I thought some e-readers were similar, where you can load a whole custom ROM on the device, and never be forced to use the stock software. It seems, I've gotten that wrong. It seems like most people with a "hacked" e-reader are simply using an app called KOreader, which runs inside the regular factory stock operating system. I guess I'll do that if I have to, but I'm wondering is there any paperwhite e-reader that has a fully custom ROM made for it? I'd like to replace the stock firmware entirely. Any hardware recommendations? Or should I just bite the bullet, get a Kobo Clara HD, and put KOreader on it?
I might need to look closer at this and whether it's an option for my max 3. I've tolerated that their version of Android kind of sucks and is kind of sketchy because it's just so much better for a reader than not Android, but I'd really like better control.
