[ROM][N 7.1.2] [ KatKiss - Nougatella #039 ]

[timduru]

KatKiss ROM

​

Nougat 7.1 Release​

Asus TF300T​

Please note that this version is made for and tested on the TF300T model.
​

This rom is an aosp based rom with my own additions on top of it.

The main motto of the rom being Kiss. Even though the Meerkat could give you a kiss, it stands for Keeps it Sweet and Simple too
Which means that the rom's main goal is efficiency, speed/responsiveness,
while not adding bloated features that will slow things down

Quick demo video of the current rom: https://youtu.be/bclpP2UJydE
You'll have to excuse the phone quality
it's mostly to show the responsiveness, launch times, switching between apps repeatedly, multi apps, video playing, floating windows and so on, it's not feature exhaustive.

Install Instructions:

Install KANG TWRP Recovery

• Backup everything !
• Boot into the recovery
  
  The first time or everytime you have an issue when dirty flashing (Especially when changing android versions):
  [*] do a full wipe , if you have issues make sure that you format /data (format is different than wipe)
  Warning: formatting will remove what is stored in your internal storage, so store the rom /gapps/supersu zips onto an external storage (microSD, SD card..) or make sure you know how to push them back through adb.
• Change /data filesystem to f2fs
  (wipe => advanced wipe, check /data then "Repair or change filesystem" => change file system => and choose F2FS)
  
  Then everytime (even when "dirty flashing") do the following steps:
• Flash the rom
• Flash the SuperSU zip
  [*]Flash gapps
• Wipe cache/dalvik
• Reboot

Note that current gapps setup wizard will crash as it is not fully compatible with android 7.1.2 (KatKiss >= 022)
unless you turn on wifi manually after the language selection in the initial setup.
(if you don't have a dock, use the extra wifi button in the navbar)

Tips

First Install
Make sure you do a format /data the first time you install the rom
(backup your internal storage first if you want to keep something)

The first boot after a rom flash can take a few minutes as ART is slower than dalvik to optimize the applications, but is faster after the 1st time.
(First boot takes ~4-5 minutes without gapps and 10+ minutes with gapps)
Also keep in mind that after a fresh install, it might take a bit of time to get up to full speed as media scanner & google are checking/scanning and restoring stuff.

Note that app optimizations /cache will now occur in background after being installed, only when :
- your device is idle
- on power and fully charged.
So after install , let your device on the charger for a few hours for it to fully optimize.


System UI Tuner
A few things including the navbar buttons can be tweaked in Settings => System UI Tuner

Hardware keyboard layouts
More languages have been added in the default asusec keyboard
Set the keyboard layout through Settings => Language & Input => Physical Keyboard (asusdec)
(to use multiple layouts , you first need to add another Language in Settings => Language & input)
You can switch between layouts using the keyboard icon that appears in the navbar.

Storage Encryption
Encryption is not supported on our devices

Global Key Override/Shorcut Mecanism
Available in Settings => Dock => Add Key Override Actions

This will allow you not only to redefine function keys assignment, and other special keys actions,
but you'll also be able to assign global macro actions / app launch to any key + Meta key combination (shift Left or Right , ctrl..)

You can also add multiple actions to one key combination, simply click again on the "+" button for the same key combination.
For example if you want to assign to one key combination a list of action to run before going to bed for example, like: turn wifi off, Bluetooth off, mute sound, and turn screen off, you can do that
Note that starting multiple applications with one key is kinda a miss and hit for the moment due to some mecanism in android that seems to prevent applications to start too close to each others.

Bluetooth audio devices
For bluetooth audio devices that have "phone audio" capability you need to uncheck the box in the device's bluetooth settings.

Camera
Video recording is 720p max

Storage (fstrim) and Database optimization:
Fstrim is native since 4.3 and will happen in the background if your tablet is idle / sleeping and that your battery is > 70%
There is also a script to run it manually in the rom: /etc/kat/optimizestorage

To optimize the Database: /etc/kat/optimizedb

To run both, open a terminal and run:
su
/etc/kat/optimize

First Beta Release #006

New rom version available: KatKiss-7.0_TF300T_006.zip

Let's go !

I've been using Nougat for the past few days and It's pretty much usable as a daily rom already I'd say
Unless you need one of the missing /not working feature of course (See 1st post)

I'll be busy for the weekend, so I thought some might want to play with it too

As usual with a major upgrade: FORMAT /data first
(it'll change it to ext4, then you simply need to change it back to f2fs)

Have fun

 

[StaticMaal]

Sorry man I thought coming soon was meant for the mirror link.

 

[thorrules]

Wow. This is very impressive, I hope to try this soon

@timduru
Did I understand correctly?
My steps when moving from version KatshMallow #029 the following:

1. Full wipe + format /data to ext4
2. Convert /data to F2FS
3. Install new ROM (7.0) + GAPPS + SuperSU

Yep, that would work
You can skip "full wipe", as data format to ext4 does the same, just more complete

Installed. Running fine.

Do I have to format f2fs even though I am already on katshmallow with f2fs?

 

[BrateloSlava]

Do I have to format f2fs even though I am already on katshmallow with f2fs?

Yes, full cleaning internal storage needed.

Do I convert /data to f2fs within kang twrp or adb with a command line?

Will this fantastic ROM become available for the TF201 as my TF300 has just gone Kaput!!

 

[Jahwio]

Is there a possibility to install google now launcher?

When installed from the store, I can't get it to run. And flashing the micro or stock gapps, results in the device not booting. And I waited for like 20 minutes. Or was that too short of a waiting time?
