Basic Information
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.
Requirements
The Eee Pad Transformer TF101 already comes with an unlocked bootloader, so no previous requirements are needed.
A custom recovery such as TWRP is not even needed neither.
Mainline Informations
Installation
|
If you haven't ever customized your TF101, please go here first. |
 |
WARNING: This mainline installation does not work for TF101G or SL101 variants! Please use downstream installation instead or use this method. We give first priority to U-Boot flashed devices than existing support to the old bootloader.
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, such as `--sbk` option) 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):

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!
Developer Info
Testing U-Boot in RAM
Nvflashing U-boot has its benefits: it acts as a temporary bootloader when booting Linux on TF101. The uboot file is stored in RAM instead. That way, you don't have to worry about flashing it permanently every time, only to test it.
To perform this, put your tablet in APX mode, download the needed files and type the following command (be aware this is for SBK1, for SBK2 you need to change the SBK keys) (not tested with SBK2, you can try this command anyway and report):
$ ./nvflash --bct transformer.bct --setbct --configfile flash.cfg --bl u-boot.bin --odmdata 0x300d8011 --sbk 0x1682CCD8 0x8A1A43EA 0xA532EEB6 0xECFE1D98 --sync
Note that there is an u-boot.bin file already in the zip folder. Please replace it with your u-boot.bin file instead.
Nvflash partitiontable.txt
Nvflash can print your partition table configuration as a better setup for offset calculations, needed in U-Boot.
To perform this, put your tablet in APX mode, download the needed files and type the following command (be aware this is for SBK1, for SBK2 you need to change the SBK keys) (not tested with SBK2, you can try this command anyway and report):
$ ./nvflash --bct transformer.bct --setbct --configfile flash.cfg --bl bootloader.bin --odmdata 0x300d8011 --sbk 0x1682CCD8 0x8A1A43EA 0xA532EEB6 0xECFE1D98 --sync $ ./nvflash --resume --getpartitiontable partitiontable.txt
After that, if you have followed all this guide, your partition table txt file should be exactly like this:
|
If you haven't ever customized your TF101, which means it's your first time using this nvflash command and you don't have used any One-Click-Unlock Tool or EasyFlasher, please report here and attach partitiontable.txt file first before continuing with the installation. |
