Hello parallel universe of Android tweakers. I have done a good hour's worth of searching and reading and just want to make sure I know what I'm getting into here. I would just do it all without asking for what I'm sure will be redundant confirmations from you, but it's not my phone (see sig).. it's for a friend who thinks my custom ROM is the shiz.
So, I just wanted to make sure I understand what I'll need to do in order to root her phone, install a custom recovery, custom rom and possible restore to stock if needed.
My friend has the SGS4 with AT&T and has the MF3 update.
1. Root via this method: http://forum.xda-developers.com/show....php?t=2387577
2. Install recovery via the Safestrap method: http://forum.xda-developers.com/show....php?t=2448925
3. Install custom ROMs via TWRP after using Safestrap method to install it
Coming from the Nexus 4 side, I'm finding I have it much easier than you guys, or though it seems. If you wouldn't mind, may I ask a few questions about the differences between the N4 and this, in regards to rooting/recoveries, custom roms and kernels, etc?
A. I think I understand, from my readings so far, that there is some importance of showing the bootloader as 'official' or something? Can someone explain?
B. As of now, there is no way to return to stock once a custom recovery is installed?
C. What is the kernel module zip that has to be flashed after a custom ROM? Does it mean I can't flash a custom kernel on her device?
D. Once the steps outlined in 1-3 above are done, should she ignore all OTA updates, and if she doesn't, what may happen to her phone, or the state of it (root access/recovery, etc.)?
Thanks for any help. If you guys have gotten these questions a hundred times, I'll apologize ahead of time. I'm only asking because I've actually done a lot of reading and am about to proceed. Hopefully what I've posted above is evidence of that.
