initiate factory reset by script

[tshering]

Could anybody please confirm whether this script looks okay? It is meant to be run from an external sd.

#!/bin/sh

PLATFORM=freescale
if [ `dd if=/dev/mmcblk0 bs=512 skip=1024 count=1 | grep -c "HW CONFIG"` == 1 ]; then
  CPU=`ntx_hwconfig -s -p /dev/mmcblk0 CPU`
  PLATFORM=$CPU-ntx
fi

if [ -f "/etc/u-boot/${PLATFORM}/u-boot.recovery" ]; then
  dd if=/etc/u-boot/${PLATFORM}/u-boot.recovery of=/dev/mmcblk0 bs=128k count=1 seek=6
  sync
  reboot
else
  mount -o remount,rw /mnt/sd
  sleep 2
  echo "Cannot find /etc/u-boot/${PLATFORM}/u-boot.recovery" > /mnt/sd/factory_reset.log
  sync
  /bin/busybox poweroff
fi

For the older Kobo Touch, if it is running on an older FW (3.0.0 and older), one would have to set the PLATFORM to ntx508.

OK, but it will take 30 min. to backup my internal uSD. <more in 30 min.>

Well, OK, I'm not sure that image got created right anyway.

Ken, I did not intend that somebody tests this. There are people around who could tell just by reading the script! Or those who want to reimage the internal sd anyway. So please do not do it.

Do you want me to look at it or do you want me to actually test it?

It LOOKS okay. I can test it tomorrow with another SD card if you like.

A different take: (only works if u-boot.mmc is identical to present u-boot)

recovery() {
    dd if=/dev/mmcblk0 bs=128k count=1 skip=6 of=/tmp/u-boot.cur

    for uboot in /etc/u-boot/*/u-boot.mmc
    do
        cmp /tmp/u-boot.cur $uboot \
        && dd if=$(dirname $uboot)/u-boot.recovery of=/dev/mmcblk0 bs=128k count=1 seek=6 \
        && success
    done

    failure
}

Could also use /mnt/sd/u-boot.backup instead of /tmp/u-boot.cur so - if it doesn't actually boot afterwards you could undo by writing u-boot.backup back to the internal microsd.

There are people around who could tell just by reading the script!

I'm not so sure. I remember I tried this recovery u-boot at some point and even though I think I did the same things rcS does, it didn't actually work for me. Maybe my mistake, maybe something missing, but testing is important in any case.

I do not want to talk anybody into something. But I am curious, of course.

Very nice take. That would also work for mark 3 Touch with old FW.

Thank you for looking at the script!

It works for me on the H2O.

Your script:

+ PLATFORM=freescale
+ dd if=/dev/mmcblk0 bs=512 skip=1024 count=1
+ grep -c HW CONFIG
1+0 records in
1+0 records out
512 bytes (512B) copied, 0.000754 seconds, 663.1KB/s
+ [ 1 == 1 ]
+ ntx_hwconfig -s -p /dev/mmcblk0 CPU
+ CPU=mx50
+ PLATFORM=mx50-ntx
+ [ -f /etc/u-boot/mx50-ntx/u-boot.recovery ]
+ dd if=/etc/u-boot/mx50-ntx/u-boot.recovery of=/dev/mmcblk0 bs=128k count=1 seek=6
1+0 records in
1+0 records out
131072 bytes (128.0KB) copied, 0.001900 seconds, 65.8MB/s
+ sync
+ reboot

My script:

+ recovery
+ dd if=/dev/mmcblk0 bs=128k count=1 skip=6 of=/tmp/u-boot.cur
1+0 records in
1+0 records out
131072 bytes (128.0KB) copied, 0.029423 seconds, 4.2MB/s
+ cmp /tmp/u-boot.cur /etc/u-boot/freescale/u-boot.mmc
/tmp/u-boot.cur /etc/u-boot/freescale/u-boot.mmc differ: char 1, line 1
+ cmp /tmp/u-boot.cur /etc/u-boot/mx50-ntx/u-boot.mmc
+ dirname /etc/u-boot/mx50-ntx/u-boot.mmc
+ dd if=/etc/u-boot/mx50-ntx/u-boot.recovery of=/dev/mmcblk0 bs=128k count=1 seek=6
1+0 records in
1+0 records out
131072 bytes (128.0KB) copied, 0.020337 seconds, 6.1MB/s
+ success

Thank you very much for testing, and also for your script.

hi
sry I'm not familar with codes
how should I use this scripts code ?
copying them in notepad++ rename file to *.sh ? copy to SD ?

these are my imagination

Your imagination is correct. And then you would need to execute the script.

If KSM 7 is installed on your device, you can name the file autoscript.sh. It will be executed when you insert the sd as soon as it is recognized and mounted by the system. This is meant for emergency cases when you cannot communicate any longer with your device in the usual ways. Do this only if you really want to factory reset your device! The process will start without asking for further confirmation!

hi
thank you for reply
yes I want to factry reset and want to try it by this method
but I don't have KSM on kobo
any other way to execute script on sd ?

If you like, extract KoboRoot.tgz from the archive and copy it to .kobo. After reboot, autoscript.sh will be started from the external sd.

Warning: This must not be installed on a device running KSM!

hi
thank you

it doesn't work for me, which script should I use ? I use post one's ( that ends if "Fi" . should I change this part {PLATFORM} to anything for H2O ?


and another question : in hypothetical case as you said there is no communication way with device, there is no chance to apply your patch " extract KoboRoot.tgz from the archive and copy it to .kobo." should I open this way every time after factory reset for emergency case

I guess I goofed it up. I have to look at the sd script again.

Edit: Yes, I did. I have replaced the archive in the post above by the new one (autorun_autoscript_sh_from_sd2.zip).

hi
it doesn't work again
can u take a look at my script file please

Use unix style line endings (LF), instead of Windows style endings (CR+LF). You can select in notepad++ the end of line character (or sequence of charactres).

You can add some lines to the script in order to give you an optical feedback whether the script is executed at all. The led will start blinking.

Spoiler:
