HP touchpad with Android
Вот уже отгремела шумиха вокруг планшета HP Touchpad, которому пророчили большое плавание. К сожалению плавание не удалось. После провала на рынке, прекращения поддержки WebOS и частичной передачи сообществу стало ясно, что вещь, конечно, хорошая, особенно за 150$, но использование ее под огромным вопросом. Однако комманда Cyanogen вдохнула в него новое будущее в виде ОС Android ICS.
На Хабре уже появлялись обзоры как непосредственно HP Touchpad, например, тут и тут, так и собственно WebOS. Поэтому я считаю, что описывать еще раз сам планшет бессмысленно, так что буду писать о том, что из себя представляет HP Touchpad c Android ICS на борту.
Как я уже отметил, на девайс ставится прошивка Cyanogen Mod 9, которая сейчас пребывает в состоянии 2-й альфы. Так же периодически выходят так называемые «ночнушки» или «ночные сборки» — промежуточные апдейты, где фиксятся некоторые баги. Тут я хочу рассмотреть как чистую альфу, так и последнюю «ночнушку»
Android 4.0 ICS (CM9) alpha
Не смотря на альфа-статус, все работает достаточно хорошо и стабильно. Иногда вылетает Опера, но когда начал наблюдать такое же на смартфоне, склонился к версии, что не в альфе дело.
— камера (хотя она и так не ахти);
— микрофон (как на запись, так и в скайпе);
— некоторые пишут про бахи с WiFi — у себя не заметил;
— некоторые игры (в основном от Gameloft — лечится манипуляциями с build.prop Chainfire);
— невоз
Экран блокировки:
Рабочий стол:
Тесты AnTuTu:
Если учесть, что основное использование планшета — инет-серфинг, почта, игры, книжки и минимум редактирования документов; то возможностей девайса хватает вполне. Добавьте к этому еще IPS-матрицу с отличными углами обзора и аккумулятор на 6300 махов — вообще красота (за такие то деньги).
«Ночнушка»
Первое, что бросается в глаза — микрофон заработал, как в скайпе, так и на запись. Камера все равно никак не подымается. Немного радует, что по данным AnTuTu девайс тоже начал работать несколько быстрее.

2)(Optional)Time to Choose the Fate of WebOS:
Note: If you wish to remove WebOS or have already removed it just skip to step # 3
If you wish to keep WebOS then do the following steps:
Uninstall Android and Clean up your SDcard:

On Windows, run the batch file named tptb_v42_win.bat
On Linux, run the script named tptb_v42_nix.sh
On Mac, run the script named tptb_v42_mac.command
-Lines of script will scroll across the HP Touchpad screen until you see the TPtoolbox main menu.

-If you previously did step number 3 and want to keep WebOS then skip this step and proceed to step 6 installing android. 
6)Installing Android on the HP TouchPad
-scroll down to Install Android from the menu and select it with the home button.
-The TPtoolbox will mount the media partition/volume to your PC. Open the Touchpads Media partition/volume on your PC and look for the ttinstall folder. Place the below Rom, Recovery and Gapps zips into the ttinstall folder. 
Download Android 4.4.4 Kitkat install files(Recovery, Rom, Gapps):
Recovery: Download TWRP-jcs-dm-tenderloin-20140612b.zip here
Rom: Download Jcsullins Snapshot CM11 build here
Gapps: Download Base Gapps 4.4.4 here
-Once the files are finished transferring to the HP TP select Unmount Media Volume from the TPtoolbox menu.
-The TPtoolbox will now check the files for compatibility then begin to set your partitions/volumes.
-If the TPtoolbox fails to run it will display which file is incompatible, start the install again and replace the offending file(s).
Note: Flintmans newest TWRP builds cannot be installed with the TPtoolbox and must be flashed from an older legacy recovery.
7)How to change the Partition/Volume sizes(Required for Android 9.x/8.1.x/.7.1.2)
-Before confirming the OS installation scroll down and choose Adjust Volume Sizes from the TPtoolbox menu
-Scroll down to the cm-data volume and select it, then scroll down to -1024 and select that
-Scroll up and go back a page in the menu, next highlight cm_system from the menu and select it
-Scroll down to +1024 and select that
-Scroll up and go back a page in the menu, select APPLY Changes and confirm the partition layout
-Now confirm the OS installation by selecting Yes and pressing the home button. Your Recovery Rom and Gapps will be flashed automatically.
Note: I recommended setting the cm-data volume to 2048mb+. Optionally you can increase the cm-cache to 400mb+, users say it could improve performance with Oreo. 
TPToolbox Auto Installs your Rom, Gapps and Recovery(Please stand by..)
-The details of partition/volume resizing will scroll across the TPtoolboxes bottom output window and the device will auto reboot into recovery. The Rom and Gapps package will now be installed automatically, this may take a few minutes, Please stand by. Once complete the Touchpad will restart and boot into Android.
Note:You now have the most stable mature Rom installed on your HP Touchpad(Milaq’s Lineage 11 Android 4.4.4). You may wish to stay here or come back to this setup if you have issues with newer 9.x or 8.1.x or 7.1.2 builds.
-I recommend making a nandroid backup at this point to easily return to this version of Android.

Follow up Q & A:
How do I update my rom to a newer version?
-To update your rom you need to do what is called a dirty flash.
-Download the latest version of the installed rom onto the device.
-Reboot into TWRP recovery and flash the rom, just like you did in step 10 but without the gapps package.
How do I change my rom, do I have to start from the beginning?
-To quickly change to a different rom download the rom and gapps to the device and reboot into TWRP recovery.
-From TWRP select the «Wipe» menu then swipe to factory reset (warning this wipes your data).
-Go back to the main menu and install the desired rom and gapps then reboot.
-Be warned switching to various versions of Android like this could cause a boot loop, if you get stuck just start over with the TPtoolbox
What Roms do I recommend?
The biggest complaints about using the HP Touchpad in 2021 are app compatibility and YouTube crashing or having distorted playback. Jcsullins CM11 Snapshot has good YouTube playback and great all around perfromace.
However older roms might not have compatibility with newer apps but newer roms aren’t as mature and reliable. This causes users to try different builds in search of what works best for their specific needs and tastes. Many issues have simple solutions, have a look at the troubleshooting section in post 3 for more assistance here. The HP TouchPad has had an incredible level of community support and aged gracefully but has reached its end of life.
#1 Android Kitkat 4.4.4, I highly recommend these builds for people who want the most stable reliable rom. This is your set it and forget it daily driver. From the golden age of HP Touchpad development, these roms have the least amount of issues and saw the longest period of development. Jcsullins CM11 Snapshot doesn’t have issues with YouTube playback like Lineage 11 and is an excellent choice.
#2 Android 5.1 CM12.1 Snapshot by Jcsullins. Another fully functional rom by the Touchpad talented one. Much like CM11 this rom has aged well. The user interface is more modern than CM11 but performance is little slower.
#3 Android 7.1.2 roms are fully functional and have good app compatibility. YouTube works well plus streaming fixes were added to the roms. I’d recommend checking out CM14.1 and Evervolv 7.1.2.
#4 Android 9.0 Pie has similar functionality to Oreo but the camera and Bluetooth don’t work. The rom is usable but incomplete. If you don’t ever use the camera and Bluetooth you probably won’t miss them. Make a backup of your current rom before installing and touring this final HP TouchPad triumph.
What Apps do I recommend?
Ad-Away, XDA thread here, Github here
Note: use build 4.3.6 here with Android versions 4.4.4-7.1.2
Blocks adds through host file blacklist. Great app been using it for many years, silly video here
Advanced Task Manager here
Note: From the 3 dots menu/settings/ select, Screen off kill, Regular kill, stat up kill and then disable auto kill notice. You can whitelist apps you don’t want killed by unchecking them in the menu.
System app remover (root needed) here
Note: Use a task manager app to identify unwanted system apps popping up in memory and remove them. Frees ram and space, gets rid of unwanted Google apps. Always make a backup before removing system apps.
PassMark Performance Test here
Note: Useful benchmarking tool to compare and contrast rom performance.
Quick System Info Pro here
Note: Great app for quick info on the TouchPads specifications, frequency’s and volumes.
3C-Battery Manager here
Note: Great app for testing battery drain and health
3C-CPU Manger(ROOT) here
WiFi File Transfer here
File Manager here
Cx-File Explorer here
X-plore File Manager here
AIMP Music player here
VLC for Android here
