The Eee Pad is a tablet computer with a 10.1" IPS multi-touch screen with a resolution of 1280 × 800 and an Nvidia Tegra 2 system-on-a-chip (SoC). It has an 802.11b/g/n Wi-Fi module.
Installation (mainline)
WARNING: This mainline installation does not work for TF101G or SL101 variants! Please use downstream installation instead. In addition, these steps will format ALL the partitions of the TF101's partition table and then recreate them but with u-boot bootloader flashed on it, instead of the proprietary Asus Bootloader. |
A Linux computer is required (virtual machine won't work). Furthermore, this installation process has not been verified by a TF101 SBK2 version but it should also work. |
Use the latest 9.2.1 firmware available, so upgrade if you need it here (mirror here).
You must know which SBK version your tablet has. For the asus-tf101, there are two versions only: sbkv1 and sbkv2.
However there is a caveat: two proprietary tools are needed, Wheelie (although source code is available on GitHub, some key features are missing) and Nvflash (proprietary Nvidia flash tool). So, a custom setup is available to get this working a little bit easier.
1. Go through the pmbootstrap installation method: `pmbootstrap init`, select your device (asus -> tf101), the interface or UI (XFCE, MATE or LXQT are recommended), `pmbootstrap export` and flash the resulting image to your Micro SD Card.
2. Now connect the device to the computer. This USB to 40 Pin cable is required.
3. Put your device into APX mode: First of all, power off the device and then press the power button + volume up button for 3 to 5 seconds.
4. Download U-Boot Tools for Asus Eee Pad Transformer TF101 here. Please read the release notes for instructions.
- If you are unsure which SBK version you have, please try both flashing methods.
WARNING: Do not unplug the USB under any circumstance. |
5. Some operations will be executed on the tablet. Please be patient, wait from 5 to 10 minutes. Formatting Partition 15 (UDA) can also take some time. In case you don't know the SBK version of your tablet, you will see some errors, or the device not booting at all. In that case, please try the other SBK version.
Expected output (SBK1 example):
user@mycomputer:~$ ./uboot_sbkv1.sh Wheelie 0.1 - Preflight for nvflash. Copyright (c) 2011-2012 androidroot.mobi ======================================== Using SBK type 1.

8. Now press the power button for a few seconds to reboot the device. After that, disconnect the USB from the device. It should be booting PostmarketOS!
Downstream informations
Installation
You have to flash a recovery like TWRP before doing this.
$ pmbootstrap install $ pmbootstrap export
Now reboot the device in recovery
$ adb push /tmp/postmarketOS-export/boot.img-asus-tf101 /cache $ adb push /tmp/postmarketOS-export/asus-tf101.img /cache
The following should be executed within adb shell:
$ adb shell # dd if=/cache/boot.img-asus-tf101 of=/dev/block/mmcblk0p4 # dd if=/cache/asus-tf101.img of=/dev/block/mmcblk0p1
WiFi setup
WiFi is provided by the firmware-aosp-broadcom-wlan package. A very similar process can be found in https://wiki.postmarketos.org/wiki/Medion_Lifetab_S9714_(medion-kai)#How_bonsaiblue_made_wifi_work.
If the package is not installed, install it. Then, rename firmware files for detection:
# mv /lib/firmware/postmarketos/bcmdhd/bcm4329/fw_bcm4329.bin /lib/firmware/postmarketos/bcmdhd/bcm4329/fw_bcmdhd.bin # mv /lib/firmware/postmarketos/bcmdhd/bcm4329/fw_bcm4329_abg.bin /lib/firmware/postmarketos/bcmdhd/bcm4329/fw_bcmdhd_abg.bin # mv /lib/firmware/postmarketos/bcmdhd/bcm4329/fw_bcm4329_apsta.bin /lib/firmware/postmarketos/bcmdhd/bcm4329/fw_bcmdhd_apsta.bin
Now reboot your device and Wi-Fi will be detected properly.
Bluetooth setup
Bluetooth is provided by the bcm4329.hcd firmware file.
Please follow these steps to get it working:
#!/bin/sh # Start brcm-patchram-plus for TF101 rfkill unblock 0 /usr/sbin/brcm_patchram_plus -d --patchram /lib/firmware/postmarketos/brcm/bcm4329.hcd --baudrate 921600 --bd_addr $(cat /lib/firmware/postmarketos/brcm/mac.txt) --enable_hci /dev/ttyHS2&
Where mac.txt is your MAC address. Works even if you generate it randomly, but it is still experimental and a work in progress. Sample here
See here for more information.
