As I don't have the time to sit and create custom roms for all these daps for free for everyone I'm sharing the tools and config for other like minded entbusiasts.

This is purposly not a spoon feeding guide for anyone so if you know what this is you probably know how to use it and how not to brick your DAP

I would ask for people to please keep discussions here rather than head-fi

Hiby R6 2020
Hiby RS6

Hello together :-)

I am pretty new to Android DAPs and I want to try rooting my Hiby RS6 but to be honest I don’t know where to start 😅

I have managed to remove a lot of services and apps via ADB but in terms of rooting I simply have no glue how to do that.

Is there maybe a good tutorial out there?
I already installed the Qualcomm USB drivers and QLiTe 😅

Thanks for your help and have a great day

I have successfully rooted the Dx300, and I am a newbie in this as well. Would be nice to see more people tweaking and tuning and or sharing discussions here

So, there are 2 boot partitions and you will need to patch and reflash on both before your dx300 is rooted

Now, onto tweaking and optimizing the system with Build.prop and Kernel auditor.

Agreed, using smartpack now and I can enjoy maximizing the neutron upsampling and upscaling performances, even with screen off and live processing all pcm to dsd256. Just exactly what I was asking for even at the expenses of the digital battery

Disclaimer: All risks are your responsiblity.  This is my first time doing this and it was perfectly safe.  I went ahead and prepare the boots partitions for you as well.  IMO, this is well and safe procedures.  
Download Android SDK Platform tools
mac.softpedia.com/get/Developer-Tools/Google-Android-SDK.shtml

Unzip and install it to a folder directory. FE, C:\Download\platform-tool

Now Open this folder directory, then use keyboard to input "Shift+Right click", and choose to Open Powershell Windows here. This will be your ADB terminals for all kind of commands.

Download Android USB Driver, otherwise you will be stuck at Device state "Locked" screen. Follows the direction to install your USB driver througoutly. Restart your PC
developer.android.com/studio/run/win-usb

Now, Download these Boot IMG, prepared for you by me with the helps of Steve. Remember, this is prepared for the Firmware of 1.05.343
drive.google.com/drive/folders/1t9EqbAb1J8O5oEw3hyz5wZuCFK6qfa_D?usp=sharing

There are 2 Boot files (DX300Boot1.img and DX300Boot2.img). Now, copy/paste or drag it and drop into the Platform-tool directory.

Back to the Powershell window.

Prepare your DX300
Go to Setting>System>About device> Tap build number until you are "Now a developer"
Back to System, open up Developer Option, Flip OEM Unlocking On, and USB Debugging On
Connect DX300 to your PC with stock USB cables

Now back to Powershell window
Type in command: .\adb devices
You will see List of Device attached and it series number

Putting it into fastboot bootloader mode with command: .\adb reboot bootloader
Now unlocking the Bootloader with command: .\fastboot flashing unlock
Your Dx300 will ask you to confirm that you are assuming the risk etc....use the side buttons to navigate and press power button to choose
Now you are ready to flash the Boot images
Flashing the boots Remember to define the location where of the Dx300Boot IMG is located at, which should be inside the Platform Tool directory and by the command: .\fastboot flash boot DX300Boot1.img
When Done, flash the next one
Flashing the second boots by the command: .\fastboot flash boot DX300Boot2.img

The best way is to drag the Boot Image and drop it right into Powershell after the command .\fast boot flash boot
Now, Your player should be done flashing, and wait for it to be up and running again.

Download your Google playstore and find SmartPack. This app is free and the best there is to tinker with Tools, Terminal, CPU government....etc....it is a playground to unlock your DX300 to it potentials.

At this point, there are so many more tweaks, and I am hoping that people will start contributing to this thread, so we can further benefit from this wonderful DAP

You can always Download RootChecker to make sure and verify that you have successfully Rooted your DX300.

Smartpack performances mode for All PCM to DSD256 by Neutron Player

Download Smartpack, and open it, grand it Super User permanently

Homescreen will have overall statistic. On the lower right corner of that window, there are 6 little dot, click on it, pick "More". You will see all Cores are flipped on Big CPU 5-6-7-8. I set minimum to 1958 Mhz and max is 2208 Mhz. Then CPU Governor to Performances. Scroll downward to Little CPU Usage core 1-2-3-4 with Max 1843 Mhz and Minimum 1747 Mhz. CPU Governor to Performances. Then scroll all the way top and flick on Apply on boot.

Now, you will be able to enjoy DSD256 Mode with Neutron while screen is off. This will drain battery fast, and the player heating up. Recommend to have the player out in the open and not in the pocket or covered.

Welcome aboard, and yes, the possibilities are now endless . I will be interested in finding out the MangoOS and how to tweak it as well

How do I limit cpu cores on other tasks as said ?

This is from an RS6 for better battery yet still allow upsampling to 384khz in neutron and no lag.
But you can import into a different dap

Save as a .json file and import onto profiles and apply/modify at will or at boot.
