Sorry in advance for long read... Before originally rooting my S4, I had the following details on OEM: Device name: SCH-I545 Android version: 4.2.2 Baseband version: I545VRUAMDK Kernal version: 3.4.0-562219 se.infra@SEP-112 # 1 Mon Apr 29 22:51:22 KST 2013 Build number: JDQ39.I545VRUAMDK Hardware version: I545.06 Now I didn't keep great records on what I did for a recovery install, but I see when I boot to recovery I have Team Win Recovery Project v126.96.36.199, and has worked find through several installs of HyperDrive custom ROM. ***What my goal is, although I'm unsure if realistic - If I remember my last experience on SafeStrap is it gives you multiple ROM slots. My desire would be to have 3 slots: having a non rooted (if possible) real basic OEM image where I could install Good for Enterprise (currently blocked by our admins for rooted devices). So just a basic stock ROM that I could pull up an use this Good App (and any future apps I needed OEM non rooted environment with). My main latest stable version of Hyperdrive which I'm quite happy with for everyday use. A ROM to test the freshest release of Hyperdrive before implementing before full use. So let me get down to my questions, assuming SafeStrap offers multiple ROM slots: Do I need I need to first restore to orig image? I think I have one saved back up dated 7-12-12, which I'm not sure is the right OEM one, but seems like It could be. I'm not sure is there is a univeral OEM image floating around I can use to return to stock that might be better approach? I also suspect that my backup up OEM was rooted before I could get to TWRP, so this rooted backup would not be desireable choice for plane jane OEM....just not sure until I test I guess. Once I have older OEM image (or newer one if one is around here for download), I believe I saw the loopholes for aquiring root have changed. I think I can find these myself if I can just get a yay or nay as to whether I'd have to deal with a new root method. I assume at some point I need to remote TWRP if I'm installing safestrap? My root process changes based on new OEM roms right? But maye I don't care if I'm using my old nandroid....dunno. Once I have root, I can install safestrap and then have multiple slots. Then the question is, can I get an OEM install in one of those slots so I can use this app that bombs when root is detected? I know I askd a lot of different questions, you don't need to answer all of them, just look for folks to poke holes through my logic before I brick my phone, and offer me any advice and links to assist. Thanks in advance for any help or offering of advice, it's GREATLY appreciated. If you tell me a particular piece just needs more extensive searching beyond what I've done, say the word. Easiest way anyone can provide me any help.
