How to enter flash mode (requires a custom bootloader)

See https://forum.xda-developers.com/iconia-a500/a500-2019-2020-t4039271 for a through explanation of how to go from stock to fully modded.

To get serialnumber, use `adb shell` then `dmesg` then look for `serialnumber` in it.

To convert the CPUID to SDK without Windows, you can use the perl code referenced on xda-developers.

The `nvflash` tool is documented by Nvidia on https://http.download.nvidia.com/tegra-public-appnotes/flashing-tools.html#_nvflash

Installation

From https://forum.xda-developers.com/iconia-a500/linux-acer-iconia-tab-a500-2020-edition-t4136023:

Follow the Installation_guide as usual, where theses specifics have to be specified when requested (this device is now in upstream pmaports):

  • Vendor: acer
  • Device code-name: picasso
  • Install non-free Wi-Fi + Bluetooth firmware: y

Only the mainline kernel is available for installation now, as downstream kernels no longer successfully compile. The user interface may be freely selected, as long as it is not one that requires 3D acceleration. To use KDE Plasma 5, add these lines to /etc/security/pam_env.conf:

QT_IM_MODULE=qtvirtualkeyboard
QT_QUICK_BACKEND=software
LIBGL_ALWAYS_SOFTWARE=1

Next, run the following commands in succession, after each one finishes, assuming the working directory contains the pmbootstrap.py script:

$ pmbootstrap build device-acer-picasso
$ pmbootstrap build firmware-acer-picasso
$ pmbootstrap build linux-postmarketos-grate

From here on out, the generated chroot can be either installed to the eMMC, or a microSD card that must be inserted at or before boot time (the latter method allows for dual-booting Android already installed to the eMMC, although it can be directly accessed from the Linux system). The boot partition always has to be flashed to the eMMC in fastboot mode, as it is not possible to boot directly off of a microSD card. If installing to the eMMC, run

$ pmbootstrap install
$ pmbootstrap flasher flash_kernel --partition secboot
$ pmbootstrap flasher flash_rootfs
(optional) $ pmbootstrap flasher boot

If installing to a microSD card, run

$ pmbootstrap install --sdcard [path to the device for installation]
$ pmbootstrap flasher flash_kernel --partition secboot


Depending on what user interface was chosen earlier in the installation process, there may not be enough packages installed to get a fully-loaded GUI. Besides the built-in Wi-Fi, it is also possible to use a USB ethernet adapter, or connect to another computer with a micro-USB cable and get RNDIS access that enables using SSH to the tablet.

After installation to either a microSD card or the eMMC, the screen should look like: Acer-picasso splash-screen.jpg
