Rooting the Galaxy S4 (DoCoMo model
I dropped my S4 and the screen broke quite badly. I got a replacement (insurance finally paid off!) and that one of course came with the latest firmware. I have heard that rooting this one may not be so easy, but it turned out to be even easier than the experience I had before.
I should note, that I don't care about rooting the stock ROM. I am cooking my own CyanogenMod, hence, all I need is to be able to flash my own ROM. And that is so much easier. In one sentence, all I had to do is flash a custom recovery onto my phone, and then I could do whatever I want, including flash a custom ROM, or restore the nandroid backup from the identical broken phone.
On Linux, I only needed to install
heimdall (the packages is available on Gentoo).
