Perfect. Are there any disadvantages to using the alternate Superuser? I've used Chainfire's for years.
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] Tkkg1994:
I have not noticed any difference (positive nor negative) so far
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] hshah:
Sorry, as mentioned in the chat, I had done most of it right... just happened to type the wrong thing above.

I think my confusion was around the fact that I didn't uninstall SuperSU and the fact that phh's SuperUser app wasn't installed.
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] Pointro:
Yeah, not having the SHH SU app preinstalled on flashing tripped me up too.

If I have v1.2 of the ROM installed, is there any point of updating the bootloader and modem through Odin? Or is it merely a prerequisite for installing TWRP?
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] hshah:
I didn't bother updating it and have seen no issues :)
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] Tkkg1994:
Bootloader and modem yes. As long as for exynos F/FD.

AP and csc has sometimes carrier bloat so I would be sure flashing a version without carrier

Hi Luca, I am still not able to get past the encryption failed message.

I am sure I did exactly as you typed but still the encryption failed message shows up.

I chose "wipe-format data", rebooted my phone, MTP-ed the rom into my phone and flashed it.

I am not sure if others have been successful but I tried everything again and again to no avail.

edit: I finally got it to work! I did not install the BL and CP which was provided in the OP and did everything else as per instructed.

No more encryption failed messages.

Thanks Luca!
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] MintiIceCream:
Hey,

I read on the forum, that you need to wipe data, then install rom immedietly. So Wipe data. NO REBOOT AFTER THAT! Then install the ROM :)

Hope it will help you out, buddy :D
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] SAO:
Finished installing.

all worked out great (TWRP & Hydra ROM).

Will be testing root etc next.

Thx again for such a quick release Luca! you don't deserve a beer but you deserve a big bottle of champagne on that one.

[Note 7 ROMs, Kernels, Recoveries, & Other Developm] Tkkg1994:
only update BL and Modem from OP and flash the rom, then you are good, so basically follow all steps and you are good

I like it, very sharp looking! My first gold phone :D Still haven't flashed anything as of yet, ill wait a couple more days. Important part is having an Exynos variant that can be rooted with custom recovery :good:
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] d.cortez:
ROM installed fine, root is working, xposed (and the 3 modules i use) are working and i'm happy! only non-ROM issue i have is i can't backup the data partition in TWRP because i can't access it (even after following the TWRP installation steps)... likely user error. :)
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] MintiIceCream:
Not your fault actually... It's samsung's encryption :D
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] Pointro:
I can confirm that Google Now & OK Google are fully functional now.

TWRP Manager (the frontend apk) gets stuck on "checking settings and root" with the magisk root. Is there a work around or anything? I don't mind manually booting into recovery to flash stuff though. It's just something I noticed.
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] THATTON:
How did you guys go about uninstalling Chainfire's SuperSU once you switched to Phh's Superuser? Did you do it from within the SuperSU app? Or just simply uninstall?

I just uninstalled the app and installed phh's version as well as Magisk Manager :)

Does anyone know how to enable multiple accounts on our Note 7?

I have done the following guide but it doesn't work for me:

1. Go to /system/ directory and open the build.prop file to edit it.

2. Inside build.prop file, add the following lines to the end:

Fw.max_users=3

Fw.show_multiuserui=1

3. Save build.prop file after making the changes and then Reboot your phone.

Yes, me too. Trying to upgrade from stock kernel/HydraROM 1.1.5 to Hydrakernel/HydraROM 1.2. After many attempts can boot into the system, but no root. Busybox can't find the magisk root. I'll try using the supersu root. (Tried Magisk/PHH superuser/Busybox with Magisk support).

Edit - If I can't get supersu to install I'll just go back to v1.1.5. (Yes I did full wipe. CSC is the old BPH6 not sure if that matters)

Edit - supersu option installs. And busybox works. Not sure if meant to have an icon for xposed?
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] yann06:
Hi

just my feedback ..fresh install 1.2 (with busybox +magisk +xposed) +pph root , full wipe data of course

Did not find Magisk and xposed even pph root

so I ve download the Xposed zipfor Magisk install in recovery.

plus download apk for magisk manager... xposed and pph root.

But if I install Busybox by set the latest .. stuck at boot (seems normal I suppose the busybox free located in /system is the only one compatible)

So I am curious why I can not see the pph root and magisk manager plus xposed , from fresh install..

thanks again

Fresh install here and there is no way to find Xpose, Magisk and pph Root, had to download and install Xposed Installer separately.
[Note 7 ROMs, Kernels, Recoveries, & Other Developm] poczynek:
You have to scroll down in Aroma and you will see you can install xposed. I missed it the first time. After choosing Magisk and pph root you have to install the pph app in Playstore.

Should work. But you forgot to set correct permissions

Yes it will work but requires a fill wipe

Only after a dirty flash or new rom install

Odex = no mods

Yeah when you wipe data after rom install then the apps are missing. Since I install them as userapps.

Otherwise (as you posted) just install apks manually. Should work just fine

Thanks for this. I can get PHH root app working with hydrarom v1.2 now. Busybox working

However, I'm still trying to get Magisk working - it may be my unfamiliarity with it, but do I install v6 first, then the manager?

I'll keep working on getting Magisk and xposed working. Several formats and reflashes - but I'll get there eventually.
