When using nvflash or APX Tool to repartition an Acer A500/A501, some people get data errors, and assume their device is bricked, and is good only for parts.

For example, the command:

nvflash --bct flash.bct --setbct --odmdata 0x100c0105 --configfile flash.cfg --create --bl bootloader.bin --sbk 0x... 0x... 0x... 0x... --go

Will output:

failed executing command 11 NvError 0x120002
command failure: create failed (bad data)
bootloader status: failed to create the partition (code: 10) message: nverror:0x3 (0x3) flags: 0

Now that OpenWRT has released a new stable version: Barrier Breaker 14.07, it was time to upgrade my D-Link DIR-835 router running snapshots to it.

Do do this, I first did the following:

1. Save a list of the packages, using the command:

opkg list-installed

Then using some scripting on the output to ignore the version numbers.

2. Updating the /etc/sysupgrade.conf file to look like this:

/etc/rc.local
/etc/syslog-ng.conf
/etc/crontabs/

If you are, like me, an Ubuntu user who is annoyed when doing aptitude full-upgrade because it stops and displays the changelog until you press "q", then here is why this happens, and how to change the behavior.

The reason this happens is that the package apt-listchanges is installed on your system. This package lists the changes before applying them.

However, by default, it stops the upgrade process until the user has provided input. The silly part is that there are no choices at this point, the user must dismiss the output and nothing else can be done.

If you upgraded your Kubuntu KDE Desktop from 12.04 (precise pangolin) to 14.04 (trusty tahr), and tried to connect your laptop to a projector, you will be, like me, frustrated with the default "Monitor and Display" settings that pops up. You can't unify outputs easily.

To overcome this, install the kde-workspace-randr package. It will provide you with an icon in the system tray where you can unify the outputs and change each's resolution more easily.

Do it using the following command, or use your favorite software installation program:
