 - For users having issues related to missing libraries or tools, re-install dependencies with `./restore.sh Install`

 - For A7 devices:

-- If you have problems with Cydia, remove the ultrasn0w repo and force-close Cydia, then try opening Cydia again
-- For jailbreak option on iOS 8 downgrades:
-  - Stashing is already enabled and `nosuid` is removed from `fstab`, so no need to install "Stashing for #etasonJB" package
+- For jailbreak option:
+  - If you have problems with Cydia, remove the ultrasn0w repo and close Cydia using the app switcher, then try opening Cydia again
   - If you can't find Cydia in your home screen, try accessing Cydia through Safari with `cydia://` and install "Jailbreak App Icons Fix" package ([Cydia repo](https://lukezgd.github.io/repo/))
+- For jailbreak option (on iOS 8.4.1 downgrades only):

   - Warning: If your device bootloops with EtasonJB, it may not work with the jailbreak option as well! (I think this applies to some but not all [8942](https://www.theiphonewiki.com/wiki/S5L8942)/[8945](https://www.theiphonewiki.com/wiki/S5L8945) users) If this happens, bootloop protection will trigger and you won't be able to open Cydia
