Sony Ericcsson Android problems and solution.
Since a few days the phone of my girlfriend (a SONY ERICSSON XPERIA Z3 dual) had all kinds of problems including the notification sounds totally gone.
I solved the problem without losing any data!
I remebered that years ago I posted on this blog (www.zibri.org) about a way to solve another problem (my phone was not going to deep sleep anymore) and I found out that just resetting a few settings solved the problem,
I used the same method to solve a lot of situations including this.
The reason why this hapens is that some phone settings get corrupted with time (freezes, battery removed abruptly or jusyt software glitches).
The simple way to solve this it to enable USB debugging mode and connect to the phone using "adb" (android debug bridge) utility.
Then issue the command adb devices (on the phone a popup will appear asking you if you want to authorize this operation.
Once authorized, all you have to do is issuing 3 commands (probably only one of these is needed in your specific case, so you can try one by one or all together).

Many 200 Mb/s powerline adapters nowadays are based on the INTELLON 6300 chipset.
Despite what can be thought looking at them, they are all using the same hardware and firmwares.
I heard many people with Netgear XAV101 or Linksys PLK 200 or PLE 200 having problems after firmware updates and many other people with other brands having much more problems because of lack of support or configuration/upgrade utilities.
So let me explain a few things I learnt studying them.
Many of 200 Mb/s powerline ethernet adapters follow the "HomePlug AV" standard. (85 Mb adapters use HomePlug 1.0 standard which is completely different).
This standard uses ethernet broadcast packets using the HomePlug AV protocol.
The interesting thing is that their firmware is made of two different parts:
a .PIB file (Parameter Information Block) and a .NVM file (the code itself).
In the P.I.B. there are many interesting things:
The branding (mac address, device name, etc) and the tone map.
Here we go! TP-Link is another company that thinks that security by obscurity could ever work. If you "backup" the configuration from most TP-Link routers, you will get a .BIN file which is "encrypted". Use this utility below, to decrypt it (so you can edit it) and encrypt it again. Have fun.

Hello again, sweet readers !
OpenRG is an embedded OS for routers.
It's based on Linux and it's inside many ISP
routers out there.
Inside OpenRG configuration file,
passwords appear in a way that can seem
to be crypted, but it's just obfuscated. For example:
Above you can see a simple deobfuscator.
