/cache 200 MB ( Standard size )
/media 1GB or 500MB ( USB Media in Android, use it to save the ROM, Gapps and Universal Settings to Flash )
HpTp_MAX provides more RAM available and Android can use over 750 MB of swap space.
/swap 1GB or 500MB ( It allows Android to store temporally Data from RAM to allocate more Memory for Apps. )
/data depends on the model 16, 32 or 64 GB ( The free space available for Android Apps and user Data )
/boot 32 MB ( Is a fixed sized ) Moboot will be created and also TWRP Recovey 3.2.

Flash the ToolBox 2015-01-08-v42 by jcsullins into /boot
__________________________________________________ ______________
After successfully flashing any of the listed ROM the ToolBox can be flash into boot to maintain the battery.
Do NOT use the ToolBox to Resize or Repair Android Volumes.
If done it will corrupt all the Volumes ( Partitions ) and a PC with the Novacom driver must be use.
The ToolBox does not display the /swap partition, it was not created for that purpose.
Only after flashing all files from this guide the /boot partition has just enough space for the ToolBox.
7. Click Here to download all the files to flash the ToolBox to boot/
Flash_TPToolBox_v42_to_Boot.zip ( delete any splash *.tga images files and copy ToolBox into /boot )
Remove_TPToolBox_v42_from_Boot.zip ( delete the ToolBox from /boot )
If more than one ROM got flash and the ToolBox was not successfully copied to /boot then use this file:
Clean_Boot_Remove_All_ROM_Files.zip
It will create a back up of the boot files and clean /boot preserving the basic files, MoBoot and TWRP.
Then the Flash_TPToolBox_v42_to_Boot.zip can be flash.
Plus the Universal Optimize Swap Settings for the ROM installed in the Tablet.
The Universal Optimize Swap Settings copies the boot uImage for the ROM into /boot.
Keep all the downloaded files in the Micro SD card (USB Media) /external_sd ( it goes by all those names )
Any of the listed files can be flash any time and a PC is not required to maintain the battery of the Tablet.
Special Thanks to Jcsullins "The God Father of the HP Touchpad" for all the unique and great software that made it
possible to transition easily from WebOS to Android.

Does seem pretty responsive, even though i have been downloading apps etc, to get it set up. I downloaded the Gapps as well not sure if that was mentioned in your post, but it will be necessary if you go with a clean install. With the DU 11/16 kernel couldnt get the play store to work. went back to the 6/18 and it worked but no videos would play...... so updated again to 11/16 and now both seem to be working ok. I think that could have been a problem with the initial ROMS, its been awhile so i cant remember but there were a few bugs there to work out as well. I will keep checking it out...

Thanks very much....much simpler

@ Touchie Pad,
Thanks for trying it out!
It will only work as intended by downloading the "Skz Kernel Optimize and Swap Partition enable" links provided.
It will not work at all by only downloading the ROM. The Dirty Unicorn ROM Kernel does not provide support for the swap file or optimized Android.
The proper Installation is:

1. Flash DU ROM "du_tenderloin-v12.5.3-20181116-0140-RC.zip" ( It has to be that in specific)

2. Flash one of the SKZ Kernel speed provided ( Without it, no optimization or use of the swap partition will happen"

3. You can install any Google Open Gapps, I have installed all version , please provide a link to the one that does not work for you and I will try it out!

4. If you want Root access you must install SuperSu and the SKZ Kernel allows System read and write ( is a complete open system)

Let me know if those were the steps you followed otherwise I will try to explain my instructions better!

Did the swap partition with the 2017.11.03 Evervolv build with nano Gapps and my tablet confuses me because it is so quick and responsive. Thank you HP_TOUCHPAD, shumash and everyone involved in making this happen.

It is FAST and you can do a lot on it, mostly is all about the settings apply in Kernel and Ramdisk that makes the magic and giving Android OS room to breath by placing in swap unnecessary services not need it at the moment, instead of killing it and been limited to only 1GB of RAM, it can expand allocating a lot of memory to the active application. Once you close the App Android will clean up the RAM and load it from the swap file and everything goes back to normal. Android is the perfect OS for swapping.
Can you share which Kernel speed worked for you?

1782000 is what I flashed of the swap enabled kernel. That speed has been working well for me so I stuck with it. I am still using a few options in the L Speed app also. Nothing that contradicts the changes you have made. Just a few extra boosts and streamlining. The battery seems to drain more slowly also. I have not reflashed the A6 battery firmware since enabling swap and I expected the higher speed to drain more but everything is working great. No problems, no worries.

Contrary to believe a higher speed will not drain your battery. By using this settings the Tablet will have an extremely power efficiency. A higher speed only means if the CPU needs power to run an App is not going to be limited by the governor, but when idle does not consume much power. The modules on the Kernel have been remove so there is no kernel workers checking on how much memory to clean and all that extra task that is not need it. If your tablet will run at 1836 you will see the big difference, but if you are using any App to improve anything you are not going to see the full potential benefit. All those apps are only setting things up that are already set and working in the background slowing things down. None of them are need it, this is been run as a Tablet mode setting not a Phone.

I did it in that order...used pico and micro, also had the problem with the AOSP keyboard stopping which i remember having when i first flashed the ROMS. I flashed the 183 kernel..... works fast but i did have a reboot on the second day and the screen was just dark, rebooted a couple times and then reflashed the rom, and optimize, and super su files ......and all is up and running again. I was seeing -220ma drain up until i reflashed it. I will give it some more time to sort it all out, and play around with it a bit. The video playing is 1,000,000,000 times better, i love it, thanks a lot

It will not work at all by only downloading the ROM. The Dirty Unicorn ROM Kernel does not provide support for the swap file or optimized Android.
The proper Installation is:

1. Flash DU ROM "du_tenderloin-v12.5.3-20181116-0140-RC.zip" ( It has to be that in specific)
All the testing that I have done and prove to be stable is on that version, I can only recommend what I have tested.

2. Flash one of the SKZ Kernel speed provided ( Without it, no optimization or use of the swap partition will happen"
All the settings are on the Kernel and Ramdisk (the boot image) no settings are on any ROM. If that Kernel is not apply no performance will happen it will be worse.

3. You can install any Google Open Gapps, I have installed all version , please provide a link to the one that does not work for you and I will try it out!

4. If you want Root access you must install SuperSu and the SKZ Kernel allows System read and write ( is a complete open system)

Yes you are correct the Keyboard stops working in most of the ROM that is why I recommend it to install the FULL Google open Apps because, it will replace the stock Keyboard with the one original from google.
The issues has been around for as long as I can remember. The only way around is to flash another keyboard after installing pico and micro or you can do it manually. I do not know if I am allow to distribute google keyboard as a separte flash-able zip file, that will resolve the issue and all open gapps will work.

which i
remember having when i first flashed the ROMS. I flashed the 183 kernel..... works fast but i did have a reboot on the second day and the screen was just dark, rebooted a couple times and then reflashed the rom, and optimize, and super su files ......and all is up and running again.

If your tablet reboots at 1836, it may not be able to sustain that speed and it will be better to go for 1782, you will still be able to do the same. The CPU does not work at that speed all the time, only if it needs to and the cap is at 1836, but if stays that high and your CPU can not handle it then it will reboot, but others can maintain it.
I will give it some more time to sort it all out, and play around with it a bit. The video playing is 1,000,000,000 times better, i love it, thanks a lot

You will be able to play videos in HD 720 using youtube app and also the web browser. I use Opera as is easy to change to desktop mode and play music with the screen off. It can play for days none stop and no reboots, you can watch movies back to back a HD 720 no issues and will never close down or reboots, that is why the use of the swap file as an extra space to allocate memory resources.
But the most important do not install any app to optimize anything, it will make it worse, all the Kernel modules have been removed, there is nothing an app can do, just work in the background and make things worse.
It is set up to run as your PC or Laptop not as your Phone, that is the difference!

@HP_TOUCHPAD I have flashed the 1836000 swap optimized kernel and left things as they are. Interactive BFQ the preferred setup for best performance? In the Toolbox I have set it just below performance with dynamic scaling as well. This TouchPad functions like a tesseract now. Speed of light? Bwahahaha, that is nothing compared to this.

I updated the guide and added the Keyboard Flash file to be use with Pico and Micro and the others. My advice, if you want the Tablet to run smooth fast and stable, flash all those files in that specific order and everything will work as a brand new device.
