Is it possible ?
So far I've found 2 images that would allow me to get root, either cloudfire or team win recovery project (twrp).
I'm a little uneasy loading an unknown bootloader to my device.
Or maybe some information beyond "run this program", "double click here" and such. I work as an embedded engineer so I like to know what I'm doing
Usually embedded devices have a 3 stage loading. First they execute hard code in ROM when power comes up. Then this code loads the boot loader, then this boot loader brings the actual linux kernel up. It is my understanding that I will be overwriting the boot loader with twrp. By image I mean a fully compiled binary that will overwrite what is already present. If it is not an "image" to you then fine, it is not. I want to know if it is possible to root the device without overwriting the default bootloader.
