Netwalker PC-T1 Recovery Notes


After trying to revert to an older kernel, 2.6.28-15-sendai, bluetooth and wifi had stopped working. Thankfully I had an old recovery microsd handy. Please see section below "Setting up recovery Micro SD" for a quick description on how to setup a recovery microsd.

Recovery process is quite simple, put the microsd in the netwalker, turn it on and hold both L/R mouse buttons on the bezel. This may take a few tries to get right, you know it is working when you see a black cursor box on the top left hand corner of the white sharp screen. When you see the black box, release the buttons.

Then you will be presented with some japanese text. It says to continue press the left mouse button. Press the L button and it will start installing (note: it may take half an hour or so, be patient) If everything is working you will start seeing progress dots appear a few minutes after pressing the L button.

Now I think I will stick to this default kernel as the 2.6.28-19-sendai update seemed to have caused more problems!

Stylus input seems to crash with the motorola softstylus, although it has sometimes happened with the matchbox-keyboard as well. There might be a bug in how softstylus receives or sends input events within X

Setting up recovery Micro SD

To create a recovery micro sd, first you need a 2GB microsd card and an
internet connection for the script to download. Take caution that it will wipe any existing data on the microsd card. When finished the recovery system will use about 1.6gb of storage.

1) Download the following http://www.sharp.co.jp/support/ex-data/recovery.sh.tar.gz

2) Open the terminal and decompress the file:
    $ tar -zxvf  ./recovery.sh.tar.gz

3) Run the script $ sudo ./recovery.sh and wait for the script to download and copy the contents of the recovery system to your microsd card.

  1. Thank you for your blog post.
    I would like to ask you for a help on recovery of my PC-T1 tablet:
    - I had made a recovery MicroSD card as described in your post. The process took about 4 hours to complete.
    - When I turn on the tablet with Left and Right mouse buttons pressed, the power light (green one) flashed for about 5 seconds and turn off. After that nothing was happen and I think the tablet turn off two.
    Could you, please, describe the behavior of the tablet when you turn it on while pressing L+R buttons? Also, could you kindly send to me a zipped file of content of your recovery SD card (except for os.tar.bz2, zimage, and ubi.img files because they are too large).
    My e-mail is tranquocbinh@hus.edu.vn
    Thank you in advance!
