Code:
/*

 *
 * I am not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please
 * do some research if you have any concerns about features included in this ROM

 * you point the finger at me for messing up your device, I will laugh at you.
 */

Talking about Overclocking:
Overclocking (or underclocking) is optional. The installer lets you choose the maximum frequency. You can set the maximum frequency individually for each CPU core in the installer. Whatever frequencies you chose in the installer will be set at boot for each CPU. Not all devices can handle overclocking. The stock maximum CPU frequency is 1512MHz. I recommend a mild overclock, like 1728MHz for daily use. Clocking higher creates heat and wastes battery for very little performance gain. (FROM ELEMENTALX POST)



talking about CPU voltages
The installer allows you to choose from several undervolting options. These automatically undervolt the lowest frequency (384MHz) where the CPU spends most of its time. The voltages for other frequencies are assigned based on the PVS bin of your phone. CPU voltages are fully customisable with apps such Kernel Tuner or Trickster Mod, but I recommend leaving these other voltages as-is unless you are prepared to do a lot of testing. Be careful, lowering voltages can cause instability. Generally, having reboots while the phone is asleep or other weird problems is a sign that your minimum voltage is too low. The minimum voltage allowed is 700mV. (FROM ELEMENTALX POST)
Max CPU Freqs avaiable (0ver stok 1512000) : 1620000, 1728000, 1836000, 1890000, 1944000, 2052000, 2160000, 2214000
Max GPU Freqs avaiable (Over stock 400): 450, 477, 491, 504, 531, 555, 585

talking about GPU Governor
In wizard you can choose also the simple governor.


Installation
You have to unlock tablet with asus app.
You have to use SevenMaxs TWRP RECOVERY for Me302kl

If you have previously flashed CM13 with f2fs filesystem on data and cache, remember to convert to ext4 again because this is an AOSP ROM so doesn't supprt f2fs filesystem.

Later this evening i'll try to flash Asus Apps and if they will work i'll make flashable zips for community and i'll share here with some screenshots.

I also will test if this AOSP has the same issues of Nexus 5 Nougat rom.

Thank you Yatto!!!!!!!!!!!!!!!!!

Well, I made what you wrote:
1) Flash ROM
2) Flash NANO Open GApps
3) Flash SuperSU version suggested as OP
4) Boot and configure your Google account
5) Install from Play Store ZenUI Launcher
5) Flash the Asus App file.

I only have to install IME apk for Asus keyboard. All the Asus Apps are working fine...
Good JOB ! ;)

Amazing, you are unstoppable! ^_^

I tried this ROM and I can say that it works very well.
I think the only bugs I noticed so far are those two that also occurred with CM roms.
The first one is those blue flashes that appear when using keyboard.
And the second one is that it' impossible to power off tablet if it's connected to a charger or PC - it'll power on again.
That's all that got my attention for now.

By the way, tutorial in the main post says "7. Install CM zip", while this ROM isn't CM. ^^

For keyboard flashing you have to enable developer options and enable disable overlay hw, or install zenui kB. [emoji6]

Some bugs:
1) adopted storage formatting exit with errors, SD card results broken and needs formatting again, but works only as external storage
2) Nougat general problem /System is not mounted as rw, so apps like AdAway doesn't work: solution is through adb shell creating a symlink:
su
mount -orw,remount /system
rm /system/etc/hosts
ln -s /data/data/hosts /system/etc/hosts
mount -oro,remount /system
3) I can't access to external SD card with mame or ScummVM emulator :(

I know about those solutions.
But I would like to see this issue fixed completely.

Offline Charging bug is present since Asus stock 4.2.2. My tab always poweron when i connect power source and it always return alive when poweroff withpower source.

Blue flickering is hard to fix. Many device have this bug after an update to lollipop and later....

Strange, I never had that charging bug on stock 4.2.2.
Anyway, these bugs are minor, nothing to really worry about.
Thank you for all hard work. :eek:

On an unrelated note: couldn't someone share a backup of EFS partition, please?

WARNING

I think I should warn everybody about this.

Be careful when restoring backups with TWRP 3.0.2.x.
At least three people have confirmed that restoring backups of all partitions using TWRP 3.0.2.x will brick device.
It happens only with TWRP 3.0.2.x, while TWRP 2.8.0.1 can restore backups of all partitions without any problems.
@SevenMaxs, do you have any ideas for why this may happen?

What you mean when you say "all partitions" ? If you restore only /data /system and /boot ? What did it happen ?

@all
Hello friends. What about battery in this rom? In cm 13 it has configured wrong.

And also, how i can backup my efs partition via dd?

And if I read correctly, if I install asus keyboard, i do not have any isues with blue flashes?
With Asus apps (Zen Launcher and Asus Keyboard) the blue flickering's gone ;)
Why you say that battery is wrong ? Only form mah reporting from some apps ?
