How to restore ASUS Transformer Pad TF300T to Stock Android Firmware
- Download the stock firmware from the official web page of ASUS. When the web site loads you should click the OS drop down selection. Select ‘Android’ and then click the ‘Firmware’. Download the latest stock firmware file and save it on your PC.
- Make sure that you download the correct firmware, as it should be the one that matches your tablets’ SKU value. Check that by opening ‘Settings’ on your ASUS Transform Pad and click the ‘About tablet’ menu. Look at the Build number and download the software SKU listed for that one. If ‘TW’ is listed on your tablet, then you should download SKU TW, and for the ‘US’ download the US SKU file.
- Extract the contents of the file you just downloaded. It will extract a new archived file and you should extract this one, too. It should unzip several files and one of these files should be named ‘blob’ and that’s that one you’ll work with.
- If your PC has the Android SDK installed on it, you will now need to download the ‘Fastboot’ zip file from HERE. In case you don’t have Android SDK on your PC, then use the info in the preparation guide and you’ll find an XDA link with a tutorial on how to get it. After the download of ‘fastboot’ is complete, move to the next step.
- Now extract the contents of the ‘fastboot’ zip and save them in a single folder on your PC. You should get 4 files within ‘fastboot’ folder. Fastboot folder should be placed on your computer’s C:\ partition.
- Move the ‘blob’ file obtained in step 3 and place it in the fastboot folder. Now you should have 5 files in ‘fastboot’ directory.
- Power off the tablet device. After that you need to press and hold ‘power’ + ‘volume down’ buttons until an alert that says ‘press vol. up to enter RCK (5s)’. Do not press Volume UP file and instead wait for the 5 seconds to pass.
- Afterwards, in maximum 10 seconds you should press ‘volume down’ and highlight the ‘USB’ option. Press ‘volume up’ to confirm the action. If you don’t press that button in under 10 seconds, then the tablet will boot instead into Android normal mode and you will have to repeat this step 7.
- Connect your tablet to your computer using the USB data cable.
- Go to ‘fastboot’ folder on your PC. Press the ‘SHIFT’ button on your keyboard and then right-click on the folder’s white space. Select from the context-menu the option that says ‘open command prompt window in this location’. Move to the next step.
- Next, you need to enter the following command lines in the command prompt window.
- fastboot devices – this command will recognize your tablet and several lines of numbers and letters will be displayed when that happens.
- fastboot -i 0x0B05 flash system blob
- Now the stock firmware will be flashed and you should wait until then. NOTE: In case the installation fails, you should re-enter the second line of code listed above to try and re-install the ‘blob’ file. You’ll know that the software was installed when a ‘finished / OKAY’ alert is shown in command prompt.
- Next you will have to restart the tablet and to do this you need to enter the following command line: fastboot -i 0x0B05 reboot
- That should be all and now your ASUS Trasnformer Pad TF300T should restart into a brand new stock Android 4.0.3 ICS firmware.
