[HOW TO] recover/unbrick/reset the WD Mybook (While Light) - Possible scenarios

anpe008 14 Aug 2009 18:11

Actual Version: v 1.1

Version History:

• v1.1 - Added "simple Unbrick Tool" option for the White Light Mybook Single Drive (thanks TeinturMan).
• v1.0 - Initial guide

The background:
I had the following 2 errors when I have tried to log-in in the web admin interface (webgui) in the white light mybook:

XML error: no wixnas object found!

—> Thread: http://mybookworld.wikidot.com/forum/t-165054/default-webserver-error

XML error: no wixnas object found! Warning: Unknown(): write failed: No space left on device (28) in Unknown on line 0 Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0.

—> Thread: http://mybookworld.wikidot.com/forum/t-171648/xml-error:no-wixnas-object-found

It turned out that the root of the problem was that i have run out of space in the NAS and the webgui config.xml corrupted (size became 0 byte) and the worst was that it seemed that the my shares folders were 0 byte as well. I though i lost all my data.

I have tried many things to recover the share folders and access to the webgui again. Thanks frater and TeinturMan for helping out. I am writing this guide based on my experience to help out others that have the same problem.

---

Table of Content:

• I) Different reset types/levels and their impact
• II) Possible scenario table to indentify what reset types you can use in your current situation
• III) Extra info: admin password reset, Useful commands in telnet

I) Different reset types/levels and their impact
Generally, the higher the reset level is, the more impact and more modification you have on the current NAS configuration, settings. It is recommended to fix your problem by going from reset level 1 to level 8, after each other, and go one step ahead if the current level could not fix your problem. (I went up till level 6. :) )

I/1) Reboot: This is the easiest one. Simply reboot the NAS. This is the same as you would go to Start/Restart Windows. Two ways to execute it:
a) in console type:

reboot

b) in webgui: Shoutdown/Reboot icon then Reboot

I/2 General webgui reset: Advanced mode/Restore Configuration/”General Restore” button
Selecting General Restore will restore all features to previously saved settings (data volume and shares settings excepted). All current system configurations will be lost (shares are untouched) and the device automatically reboots after the restore process. Do not mixed it up with the "Restore Default Configuration " option in the page!

I/3 Soft reset (reset button on the back): Same as "I/2: general webgui reset" just it is executed by holding down the reset button at the back of the NAS at least for 10 sec when it is running. If the soft reset was successful the NAS reboots.

I/4 Hard reset (soft reset while powering up): Shutdown the NAS. Unplug the ethernet and the power cable. Plug in the power cable. While the NAS is powering up hold the reset button at the back for at least 40 sec. Plug the ethernet cable back. Start the NAS.

I/5 Manual webgui firmware upgrade: go to my other guide to Point 1 "Update firmware”
http://mybookworld.wikidot.com/forum/t-165210/how-to-set-up-wd-mbwe-white-light-properly-transmission-1-72-automate-and-manage-torrents

I/6: Forced manual firmware upgrade via console:
This is what i missed in the forum the most: to upgrade the firmware from console if weggui can not be accessed and want to keep my shares content as well.
Thread: http://mybookworld.wikidot.com/forum/t-163874/manual-firmware-upgrade

Steps:

wget -O unpack_fw http://wd.mirmana.com/unpack_fw.sh
sh unpack_fw

This will download firmware from WD's site.
To start the upgrade process you enter the command:

nohup /var/upgrade/upgrade1.sh &

and wait……

I/7 Default webgui reset (Restore Default Configuration): Advanced mode/Restore Configuration/” Restore Default Configuration” Button
Restoring the device to the Factory Default will destroy all data on the device, including all configuration setup, all shares, and all user data and media files. After the restore is complete, the device configuration will be identical to its state at purchase (“virgin”). To use the device, the initial setup will have to be performed again. The LAN settings (including port settings) are not changed. After the reset, the administrator login/password will be changed to “admin/admin.”

I/8: Recovery outside of the box (External recovery): If worst come to the worst and neither of the previous points solved your problem you have to perform external recovery. You will need to take the hdd out of your mybook, connect it to a PC/laptop,
1) run a ubuntu live cd and recovery/fix the errors in linux. Thread: http://mybookworld.wikidot.com/forum/t-171834/my-book-world-edition-white-unbrick-guide
2) use "Unbrick Tool" for the White Light Mybook Single Drive under XP to rewrite the 3 system partitions of the Mybook with new ones (using the windows dd version) and keep the Data partition (4th) untouched.

Detailed description: http://highlevelbits.free.fr/index.php?option=com_content&view=article&id=107

II) Possible scenario table to identify what reset types you can use in your current situation

III) Extra info:
III/1 admin password reset: http://mybookworld.wikidot.com/forum/t-175057/can-not-log-in-into-webadmin-gui-w-admin-admin-after-hard-reset

III/2 Useful commands in telnet:

cat /var/log/messages – check system log
cat /etc/group – list groups
cd /ect/init.d
cat /etc/version – list current firmware version
ncdu – disk usage
/opt/bin/ipkg update - Update list of available packages
/opt/bin/ipkg upgrade - Upgrade all installed packages to latest version
/opt/bin/ipkg/install <pkg> - Download and install <pkg> (and dependencies)
ls –lah - List information about the FILEs (the current directory by default), -lah=use long listing format. show all files, sizes in human readable format
pwd – list current path
reboot - reboot
top – list running process
df -h – list mounted filsystems to check their size/used%
sfdisk -l - list partitions of each device
ps -efu root – list all processes, full output format, by effective user ID (supports names)
rm -rf [dir] – delete folder
passwd – change admin password
dmesg – prints the message buffer of the kernel

Endword:
If you know another way then the above-mentioned options or if something is not correct please free to post it .

Some comments to point
I/6: Forced manual firmware upgrade via console

Here is my full console output. I must start the script with "sh unpack_fw" not "unpack_fw.sh".

Now run "nohup /var/upgrade/upgrade1.sh &"

The script works fine.
After the reconnect I found a clean mybook.

For the reason, that wd.mirmana.com is offline - Here is the full listing of unpack_fw.sh

Any idea, how we can format a clean (new) HDD with this decoded parts of firmware?

Hi tomas123,

yeah, I am working on this… currently I am stuck on figuring out how exactly to install a
kernel on the HDD, maybe someone can help:
- I know how to compile the kernel and kernel modules
- However, it seems we need a "uImage" but "make uImage" fails because there is no "mkimage" command
- I found the source for "mkimage" in kernel/kernel-source/vendor/u-boot/tools but did not manage to compile it yet
Yes, I know there allready is a kernel image in the unpacked upgrade, but I need to know this anyway.
I further would like to know if u-boot also would accept a modified kernel image (lets say, a more recent kernel version with some bugs fixed) without the need
to modify the u-boot loader itself. Any help on this will be very appreciated.

Bleep

Hello, I used the I/6 procedure, I had to adapt the firmware URL in the unpack_fw with this one:
http://download.wdc.com/nas/wdhxnc-01.01.16.img

The process finished correctly, apparently updated part of the firmware, since the root and admin password was set with the default onces, but I am still getting this error in the browser:
XML error: no wixnas object found!
And the /proto/SxM_webui/admin/config.xml is still empty!

PLEASE, I need the /proto/SxM_webui/admin/config.xml, could someone paste it's content, upload it somewhere or send it to me??? PLEASE, HELP! I can't use my MBWE anymore.

THANK YOU

i have the log-in screen to log-in into the webadmin page but whatever i did (reset button at the back, unplug->power up + reset for 40 sec) did not help. All other users did not work as well.

-admin/admin, admin/123456 did not work.

I have samba access to white light (admin/admin), SSH console connection

I have already made a firmware upfrade via console still locked on the same situation

Do you have a solution to reset admin pass from the console… ?

In my situation I should use I/8 scenario. But I've got MyBook with double drive. I think this scenario is not possible for my MyMook, am I right? And is there any other ways?

Dav-M 29 Aug 2012 19:33

Hi,

If you need to full restore a MyBook World Edition II with 2 drive, you can use the restore done for single drive, because it's the same firmware, I can confirm it works because I've use it for upgrade 2x1 to 2x2.

Just restore 1 disk, boot with this disk, and after plug (power off) the second one and format it after boot from the first disk.

I suggest you to follow this : http://iknowsomething.com/how-to-fix-bricked-wd-my-book-world-edition-or-install-brand-new-disk/
