The main issue with the Tablet has been a dead battery, not turning on and showing a battery symbol.
The condition has been associated with the Tablet been brick as it just kill itself, I will call it Suicidal Mode.
From my experience and by coincidence I have seen how a Tablet that has been off for days will turn on by itself.
Once a Tablet turns on by itself, it boots into the moboot menu and then to the default OS, Android or Recovery.
It will stay on until the battery gets depleted then it shutdown, without the user been aware of the Tablet's Suicidal Mode.
Another possible scenario is when traveling with the Tablet. Sometimes it needs to be pack or place in storage.
It only takes the power button to accidentally get press for the Tablet to boot and drain the battery.
There is no option or command in moboot to select shutdown by default when the Tablet turns on, paving the way for the Suicidal Mode to be executed.
The solution is PowerOFF, if by any means the Tablet turn on accidentally and the user is not aware it will turn off automatically preventing booting into Android or Recovery.
When to Flash PowerOFF:
When taking the Tablet on a trip or is going to be handle unsupervised.
The Tablet will not be use for a period of time or place in storage.
The user does not want the Tablet to automatically boot into Android or Recovery, but stay off.
If the Tablet is full charge and place in normal room temperature it should last approximately 6 month or more.
The following files can be flash in TWRP Recovery:
Click HERE to Download PowerOFF
1. Flash_PowerOFF.zip -- Copy uImage.PowerOFF into boot and makes it the boot default.
2. Remove_PowerOFF.zip -- Remove PowerOFF from boot and makes Recovery the boot default.
To make the Android version the boot default, re-flash the HpTp from the already flashed ROM.
There is no need to re-flash the ROM.
If the /boot partition is full and PowerOFF can not be flash or work properly then flash:
It will create a backup of /boot into the Micro SD Card.
Delete all Android boot images, freeing space to copy PowerOFF.
How PowerOFF works.
The flash file by FLINTMAN-update-TWRP-touch-data_media-SELINUX-TEST-Build_4-25-14.zip
Is modified and reduced to turn off the Tablet instead of launching TWRP.
The size of PowerOFF is 5.1MB which allows it to coexist in the boot partition with TWRP Recovery 3.2.1 and any Android boot uImage.
Many thanks @flintman for porting TWRP Recovery to the HP Touchpad that has made it possible to flash any ROM, also for all the great Android ROMs....!
