Titanium Backup – enable write access to external SD Card March 6, 2016

Recently I’ve been trying a couple of Android devices. I used to focus on iOS but I become a little bit bored with it lately. The deep customisation options on (rooted) Android devices began to fascinate me again.

When I played around with a recent and quite good Samsung tablet I ran into a couple of issues with Titanium Backup and an external 128GB SD Card. By the way rooting of said Samsung tablet is easy and straight forward.

Namely when trying to back up a couple of applications to that external SD Card, Titanium Backup showed: “readonly” / “this folder is not writable”. That seemed strange as I had even formatted the SD Card in the freshly set up tablet.

Well after a quick google search here is the solution (you will need root access, a file manager and a text editor – I used http://www.estrongs.com/?lang=en )

  • navigate to : / system /etc/ permissions/platform.xml
  • finde the section “WRITE_EXTERNAL_STORAGE”
  • inside that section add the following line:  <group gid=”media_rw” />

After a reboot of the device read and write SD Card access from within Titanium Backup worked fine.

If your PC has a slightly older USB 3.0 Controller Chip it is likely to be one of the Renesas USB 3.0 Host Controller Family. The Chip might be a Renesas/NEC µPD720200, µPD720201, or µPD720202.

For all of these I recently found good drivers on the internet.

Refer to these pages for details:

(My latest information is that latest drivers for the higher numbered chips …202 are: and for the lower

LG Nexus 4 Production Information February 18, 2013

There are quite some information available on Google’s new Nexus smartphone (manufactured by LG). Recently the android community discovered how you can find out details about your own Nexus 4’s production. My brief summary here is largely based on details given in this forum thread.

So let’s get started.

How to find the hardware revision of your device:

  •  If you know the Serial Number from the box of your Nexus device – remember it.
  • If you do not know it:
    • Find the IMEI of your device (i.e. by going to the dialer and entering  *#06#)
    • Go to the following website (while inserting your own IMEI at the appropriate position)
      http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=<your imei without hyphen here>
    • The resulting String shows interesting details and the serial number of your model in the 4th block – so at some point after A?????

Now you can either look at the serial from the box or at the above mentioned string:

Production date is encoded in the first 3 positions (reading from left to right):
1st position defines YEAR: 0 – 2010, 1 – 2011, 2 – 2012, 3 – 2013 and so on
2rd and 3rd define MONTH: 01 – January, 02 – February, 03 – March, 04 – April, 05 – May, 06 – June, 07 – July, 08 – August, 09 – September, 10 – October, 11 – November, 12 – December

4th position defines production country:
K – Korea, C – China.

In the 3rd block (A????? Block) of the aforementioned LG website output there are also some production details encoded. First letters after A seem to specify destination country / country of sale (more on that below). 4th digit in that block specifies internal storage size (8 – 8GB and G – 16GB).

AHKGBK – Hongkong, some retailer
ADEUBK – Germany retail 16G (probably Mediamarkt)
ADEGBK – Germany Play store 16G (Google_Open_16G)
AHASBK – Hutchinson “Three” Austria
AESGBK – Spain Play store 16G (Google_Open_16G)
AFRGBK – France Play store 16G (Google_Open_16G)
AUKGBK – UK Play store 16G (Google_Open_16G)
ADE8BK – German Play store 8GB (Google_Open_8G)
AAUGBK – Australia, Google Play store 16G (Google_Open_16G)

Now additionally: If you want to find out which “hardware revision” your device has:

  • boot into bootloader = switch the device off, then switch it back on while pressing volume down and power 
  • common know Nexus 4 hardware revisions are 10 and 11.

Usable Portable DVD Player October 20, 2008

Flights can be sohooo long. So what can we do to make the whole thing more bearable? Not much.

I am still searching for the most convenient mobile device to get the job done but I don’t think there is any.

So If I would have tons of moneys and the sense that I want to store and carry tons of devices (where all of them harm the environment during the production process etc.) then a mobile movie player should also be part of the device set.

Ideally a light weight laptop with an actual battery capacity to last me 5 hours or more would be nice. But unfortunately I have not found a device like that yet. All the nice and thin laptops do not last 5 hours. If you really use the machine then some of the good ones make it about 3,5 hours. But 5 hours seems almost impossible. Also for me it seems like if you actually use your device on the road then after one year the battery starts to deteriorate so quickly.

Well and in this context a rather cheaper mobile DVD player that also plays DIVX movies and offers two headphone jacks seems like a fairly reasonable device. It is bulky but more light weight than an actual laptop. It plays DIVX and MP3 music also from a USB stick (hopefully with even longer battery time because no parts have to be moved). So if you feel generous than drop this one into the basket.


Update: Well well well. I think I have to correct myself here. First of all I don’t think the word good fits to this category of products any more. If anything these devices are made by cheap producers and they are sold by heavy discounters.

I have to admit: the technology moved on. Now devices like the iPad seem much more attractive for taking on a long flight. So I don’t want one of these any more :-) and I think it is fairly safe now to take this post off of the “Wishlist” category.

Leave it in the box! February 20, 2008

Toshiba HD-A2 HD-DVD Player Thumbnail Width 460px

The High Definition DVD successor format war is now over. Toshiba has confirmed that they will pull out of all HD-DVD format products by March this year.

Although many believe the HD-DVD format to be beneficial for the customers (no region codes, more flexible dye structure etc.) the winner is apparently the Blu-Ray Disc format.

Oh well… So you might just leave your new Toshiba HD-A2 in the box or return it to your “archive” as Toshiba has already done on their website.
