Hey all, have a few questions, I hope you can answer in laymans terms.
First of all, my att htc one 64gb is now unlocked/superuser/twrp recovery/rooted/and s-off.
I'm running the stock software that came with the phone, and to be honest, I've used aosp on my droid incredible, but for now I kind of dig the stock sense feel. So I wanted to flash a upgraded stock sense rom. I saw this one
ROM][9/11/13] AT&T Leaked 3.10.502.2 - Android 4.3 / Sense 5
I read through that thread and learned a lot and also confused the hell out of myself. With my droid incredible, I'd download a new rom to my pc, transfer it from pc to sd card and then reboot to recovery, wipe data/system/cache/dalvik cache/ install rom/ reboot. Done!!
I'm guessing the principle is the same on the htc one, however, this doesn't have an external sd card, so if I transfer the new rom onto sd card, which to me is really internal memory on this phone, then reboot to recovery, wipe, well wouldn't I lose everything on that sd card (internal memory), including my twrp folder which has nandroid backup?
That's my first question.
My second question is that same rom I highlighted above has an rom and ruu download. Now if I have read correctly, the ruu has the rom plus firmware updates, like hboot, radio, etc. You can't flash this via booting into recovery. I believe it said you flash into fastboot, which I'm a little green on exactly that process.
I also see, that if you flash an ruu, you lose root, custom recovery, and pretty much everything except s-off, so I guess you have to redo those things again.
Like everyone else, just don't want to fry the thing, so figured I'd better ask questions first
