Quick question: after installing this rom, Feel the Wear became "incompatible" with the watch. It worked in the official one, even with this rom's kernel.

Anyone got any idea ?

Installed the ROM on my son's watch. Installed busybox and magisk v23 which I found online as the links in the op are dead.

When I open magisk app, I see I need to download the full version...???
If I click ok.... It fails after 2 mins as install is not ok on wear etc....

Is there a workaround..... Or even better, does anyone have links to busybox and magisk that work with this install.

I use Magisk 21.4 as this was the last version which is working fine for me. Download from Github. Busybox I'm attaching to this post

Thanks for that.....turns out i needed to push and install the magisk manager via adb.
Its 2 years since i did this with my old sawfish and i struggled then too.
I now have operational magisk manager....

Spoke too soon...... when i go to change grant permission auto it only gives the option to prompt.......will install your version and see if that fixes it.

How do you install Magisk? I do it in TWRP and no issue like that

Does anyone still have any of the early versions of this ROM (Android 7.1.1 Nougat) or if not, then a stock original Nougat ROM?

All the early Mega links are dead, unfortunately, and I'm keen to see if Assistant and battery life were better on the original ROMs.

Would be greatly appreciated!!

Did you FLASH TWRP instead of boot to it? Sound like that. You may need to restore original recovery. Take a look here: https://forum.xda-developers.com/t/...180926-001-a1-22-jan-20.3705589/post-85194917

    - Linux version 3.18.24 (gcc version 4.9.3 20141215 (prerelease) (UBER-SaberMod-4.9.3_arm-graphite)) #1 SMP PREEMPT Wed Jan 22 9:45:39 CET 2020
    - Forced-encryption disabled
    - dm-verity removed/disabled
    - Auto memory killer set to default
    - Sepolicy is patched
    - Fix the CPU idle latency unvote timeout. It should reduce the wasting power and CPU go to deep idle states immediately after a request
    - Add and use a timer frequency of 100 Hz. It should improve power consumption.
    - Add and update/Hide verifiedbootstate from /proc/cmdline in order to fix the failed SafetyNet CTS check(It can still fail through other means)-GOOGLE PAY SHOULD WORK. USE MAGISK TO HIDE ROOT. U may need Gpay enabler
    - Remove verifiedbootstate flag from /proc/cmdline - Disable CRC check
    - Scheduler optimize/support for heterogeneous multi-core
    - Scheduler support for heterogeneous multi-processor systems
    - Enable all core with scaling_available_frequencies (200000 400000 533333 800000 1094400 1267200 MHz)- scaling down the frequency of the CPUs to 200 MHz during idl mode and rise the freq. to 1.26Ghz during high pressure.
    - Set swappiness to 60
    - Change zswap max pool % to 20%. It will reduce CPU usage a lot
    - Enable zram & zswap and add 256MB virtual memory default. It will speed up the device a lot
    - Removed nolog usage, remove rtb logging from the kernel
    - Remove selinux auditing from kernel for lower overhead
    - Remove IPC logging from the kernel
    - Disabled some kernel parameter to speed up the performance- at the cost of battery/ power consumption
    - Remove some logging from several drivers
    - Improve memory allocations -Should improve the device a lot
    - Add some tweaks to improve the overall speed, apps startup are too faster
    - Set zswap compressor to lz4 by default
    - APM driver updated again to reduce battery usage during sleeping
    - Several other patches to reduce battery usage
    - Multi-core scheduler enable/optimized
    - APM driver updated reduce battery usage during sleeping
    - Fix the wake up time. The screen should wake up more quickly when pressing the button.
    - Tweaked the scheduler to reduce/save power by scaling down the frequency of the CPUs or idling them,
    - A lot subsystems converted to use power efficient workqueue
    - The watch goes to sleep during no action in order to save battery
    - Remove debug event logging-Kill the useless logging to reduce overhead
    - Remove sync debug entirely to cut down CPU waste in the frame render hot path
    - Remove 10 ms CPU idle latency unvote timeout- Doesn't force the CPU to stay out of deep idle states for far longer than necessary, which wastes power
    - Disable audit support, usually comes with a measurably significant amount of overhead
    - Remove audit dependency

    NOTE: THERE IS NO NEED TO FLASH THE LATEST KERNEL IF YOU FLASH THE LATEST ROM.

    I would like to thank you all for your generous donation. Thank you very much for supporting me. I really appreciate that. It will give me more energy to bring something nicer for your device in future.

    I will probably spend these donation to pay for the storage (online storage) for uploading the zips as well to buy a new harddisk for my PC.

    Once again, thank you for your generous donation.
