[Nexus 9 Android Development] wantowan2:
That patch isn't for gapps its for webview. The thing is, webview was pulled out of android and put into playstore as an app. So it can be updated between android versions. It because of phone vendors not updating there devices more then twice so you have ROMs out there from ICS to now.

Couple things after reading through the thread a bit. There are always probs bumping the device up an android version . usually security based crap. So:

-Don't be afraid to ( I've been using open gapps...) Go back to recovery after install wipe dalvik/cache and reflash gapps.

-go back and make sure you have followed the instructions again for all the SU stuff. Installing the pph superuser from playstore seems to matter.

-start over if you need to. Face it, if titanium backup doesn't work, don't try to shine $H1t... lol

You have bootloader and vendor on there so reflashing all the other stuff is quick.

-don't rush it. Its OK to flash the ROM and gapps then boot. The *.rc files for root are there so you can do su any time. Plus the kernel is "insecure" or even su wouldn't work. Have the su zips you need on the device and go back to do those. Then go to play store for the pph su.

-PERMISSIONS! If something is not working. Go to (this is better from titanium backup if its running OK) settings/apps. Click the app and check a couple things.

1. Stop to app. "FORCE STOP"

2. Go to storage. "CLEAR DATA".

3. Back out of there and click Permissions. Make sure all of the permission toggles are to the right(on). Android has taken up this perms on an ask only basis. Right now it sucks.

****(If you restore an app from titanium backup, you WILL have to confirm perms again now for a given app. It may not always ask when required!)****

4. Retry that and see if it works. If not, try a reboot before you try it. I had probs with contacts and calendar not syncing. If this happens, play store will not work no matter what you do. So you might have to start from "PERMISSIONS" above plus reboots to get these to sync then play store then pph su app from the store. Check that Magisk manager to see if all is well.

To be sure, this superuser is quite cobbled together. It works but it is a kind of antiquated method the way Koush's su works. The logs are just littered with su log spam. HUGE! lol I agree with the previous post. No matter what I did, SuperSU won't go. I made a package from 2.78 plus busybox in a flashable .zip and still nothing. Same from terminal+fastboot.

Mine seems as good as it should be at this point. Apps work, it syncs, titanium works as well as other root apps.

Good Luck.

Edit: I don't really recommend this but I was coming from a version of pure nexus I compiled. V.6.01. Because you have to

flash the recovery, bootloader and vendor image for v.7

Your sdcard won't be accessible from recovery. It looks empty.

You can't wipe system, cache and dalvik.

I side loaded this ROM dirty right on top of pure nexus. lol

Well, they were close enough with the file tree and fstab stuff so it worked. Even my wall paper was there. All my apps, everything! Haha The built in backup function in the updater treated it as if it were a regular OTA from google.

So because I could then boot to recovery, everything on my sdcard was there to use now. So I started over like a normal ROM.
