Galaxy S5 Lollipop Update Issue

So I finally checked the software update availability on my Samsung Galaxy S5, and guess what - the Android 5.0 update was available. Finally. I cleared up some space on my phone (it claims that it needs 3 GB of free space for the installation) and started the update. It is a big image (1.4 GB), so it takes a while to download, then the phone shuts down, restarts, and starts to install. I started wondering when the installation process started at 25%, went down to 1, up to 20, 30% and then - "error". Phone restarts, everything OK except for the fact that I still have KitKat on my phone.

Tried again. Same result. Tried again. Same result. Googled it. No results. Nobody seemed to run into that same error. There was indeed an error message after the phone restarted successfully - "Try it again, try Kies or go to a service center" (I paraphrased). Service center? Nope, no time, plus I got the phone in Germany and I wont be in Germany for quite some time.

So I tried Kies. Downloaded the software, started the firmware upgrade - download interrupted at some point. Tried again. Tried again. Tried again - it started the installation process on the phone, finally. But it stopped at about 80%, complaining about the size of the image.

Again, no real help on Google. I read something about that you could run into trouble if you made modifications to the ROM - my phone is NOT (yet) rooted, everything as I got it, I updated everything there was to update.

Kies suggested an emergency recovery. I tried that. It stopped at like 80%, leaving me with a phone I couldn't even get into recovery mode. Kies suggested emergency initialization - meaning that all data would be lost. Nah, I wasn't that desperate yet - download mode was still working!

After some thinking I decided to flash that thing myself. I got Odin and the current firmware (I decided to go for 5.0 right away) from SamMobile (I checked the exact version of my phone under the battery pack and selected "Germany" as a country), unzipped the file, and started flashing. Some minutes later the installation completed, the apps were updated and my phone back to business. No loss of data.

Thank you, Samsung, for nothing. The only reason I could think of that might have caused this issue is the regional differences. I am using the phone with a foreign SIM card, in a foreign country - probably a wrong ROM was selected by the general Samsung update process. Somewhat embarrassing...

TL, DR:
If you run into update issues with your Galaxy S5, consider flashing with Odin right away. Might save you some time and energy.

Joomla! 2.5: Multiple views, one model

Here goes MVC again: I was a bit confused that every time I created a second or third view for a component, I had to create a separate model for it. Did not make sense to me - I had the necessary algorithms in the model for the first view, did I really need to do copy & paste? I hate it! Redundancy, redundancy, redundancy.

That case occurred in my current project - I created user profiles and needed an "edit" view. The data is the same, but I need to have the data in editable text fields instead of fixed labels, and maybe some other buttons here and there... 

Well, some time later I realized that I just did not quite understand what Joomla! acutally means by "view".  And that there is something called "layout".

Long story short: If you have a model that provides all necessary information and you just want to have a different presentation of it, just add a new .php file to your views/<yourviewname>/tmpl folder - let's call it "layout2&q…

Recover Joomla PhpMyAdmin MySQL Database

This morning I found myself confronted with a new problem:

Our server crashed, we had to set it up again - from scratch. Fortunately, we did have some backups - the Joomla! files, and the mysql folder (on Linux: /var/lib/mysql).

(We are using a Linux server with mysql and phpmyadmin.)

I then tried to recover our database. What I thought: Just copy the contents from the database backup folder (mysql/joomla) to the mysql folder on the server and everything should be fine. That was what they said on the internet, too. Turns out there were only .frm files in that folder, no .myd etc. Turns out that .frm only contains the table structure. But where is my data?

Everything's not lost.

I found a huge file in the mysql backup folder, called ibdata1.

So what you need to do now is (instructions are for Linux):

- Stop your mysql service
  sudo stop mysql
- Copy that ibdata1 file to the /var/lib/mysql folder (consider making a backup of the existing ibdata1 file)
  cd /var/lib/mysql
  sudo mv ib…
