* iPad Jailbreaking/Downgrading
** iPad 1: just use [[http://3u.com/][3utools]] to update/restore and jailbreak
** iPad2,3 or iPad3,2
   We want to be on an untethered jailbreak, which seems to mean iOS 8.4.1. Some sources claim it is also noticably faster
*** steps:
    1. JB with Phoenix (via https://jailbreaks.app/legacy.html or 3uTools)
    2. Follow instructions here to downgrade to 8.4.1: [[http://www.3u.com/news/articles/5841/untethered-downgrade-iphone-5-ipad234-ipad-mini-to-ios841-without-shsh][Untethered Downgrade iPhone 5/iPad 2,3,4/iPad mini to iOS 8.4.1 without SHSH]]
       - Use 3uTools v2.55, or it will hang! (as per https://twitter.com/3utools/status/1455107861172797449)
         - specifically, 2.58 was bugged at time of testing
         - can be downloaded from http://www.3u.com/update-log
       - for iPad3,2: Use [[https://github.com/LukeZGD/iOS-OTA-Downgrader/][iOS-OTA-Downgrader]] to enter kDFU instead of kDFUApp
         - Ideally this would work for the whole downgrade, but it was a bit buggy :(
    3. install jailbreak (preferably daibutsu):
       - https://github.com/LukeZGD/iOS-OTA-Downgrader/wiki/Jailbreaking
       - used Sideloadly on MacOS
       - daibutsu did not support iPad2,3 so EtasonJB was used

* Initial Setup
  1. install "openssh" and "apt 0.7 strict" via cydia
  2. ssh with =ssh -o PubkeyAuthentication=no mobile@iPad=, password =alpine=
  3. =su= to root (also password =alpine=)
  4. change passwords for mobile and root users
  5. =apt-get install sudo vim=
  6. edit =/etc/sudoers= to allow =wheel=
  7. edit =/etc/group= to add mobile to =wheel=
  8. run =initial-setup.yml= playbook
     - sets up ssh pubkey auth
     - installs Python 2.7, needed for most ansible commands (retrieved from https://github.com/linusyang/python-for-ios/releases)
  9. run =ipads.yml= playbook
     - installs [[https://cydia.akemi.ai/?page/net.angelxwind.mikoto][mikoto]] to disable OTA update notifications (and some other things)
     - installs libactivator
     - installs =Maximization= (=be.rud0lf77.maximization=) for fullscreen/status bar hide
     - makes a webclip for https://reservations.claremontmakerspace.org, with tools defined in =hosts= file

* Other notes
** iPad lock/unlock via activator
   #+begin_src bash
     activator send libactivator.system.sleepbutton # lock
     activator send libactivator.lockscreen.dismiss # unlock
   #+end_src
   - Use Activator to schedule
     - might just be easier to config manually
     - activator config is in =/private/var/mobile/Library/Caches/libactivator.plist=
     - can't do =LAScheduledEvents= events via =activator set=

** Fullscreen/status bar hide
   - =Maximization= (=be.rud0lf77.maximization=) seems to work fine on iPad 1/2/3 and doesn't need to be applied manually
   - =Monocle= (=com.rpetrich.monocle=) works on iPad 2/3, but not iPad 1

** Editing preferences
   - can use plutil from http://repo.bingner.com/ to convert from/to binary plist
   - to restart the preferences daemon after editing a plist:
     #+begin_src bash
       launchctl kickstart -k system/com.apple.cfprefsd.xpc.daemon
     #+end_src

** Making a webclip
   - can place an Info.plist and icon into =~/Library/WebClips/<whatever>.webclip= then respring and it kind of just works
   - can launch with =activator send com.apple.webapp= maybe?
     - only seems to work when it is already running (ie to switch to it, not launch it)

** Kiosk mode
   - in iOS >=6, just use guided access
   - +in iOS <=7, maybe use IncarcerApp+
     - doesn't seem work on ios 5 anymore, so no point
     - tried older versions from [[https://code.google.com/archive/p/iphone-incarcerapp/][Google Code Archive]], but those don't work either. Maybe some incompatibility with another jailbreak library?
   - "Store Demo" mode (see [[https://stackoverflow.com/questions/5011774/lock-down-iphone-ipod-ipad-so-it-can-only-run-one-app/8994690#8994690][StackOverflow answer]])
     - works on iPad 1
     - is kind of annoying, and doesn't disable touch screen
       - can be escaped via =killall SpringBoard= or rebooting

** Let's Encrypt certificates
   - Can install cert PEM via gui, probably too much of a pain to automate it
     - profile installed as =/User/Library/ConfigurationProfiles/<something>.stub=
     - enabled in =/User/Library/ConfigurationProfiles/PayloadManifest.plist=
     - cert also enabled/trusted somewhere else?
   - seems like it will only install one cert per pem, so install ISRG root cert
