Factory reset Kindle with semi-frozen screen

The steps for performing factory reset of a Kindle are quite easy:

  1. From the home screen, select Menu.
  2. Select Settings.
  3. Select Menu again then select Reset Device.

The problem appears when your screen is frozen and you don’t see anything or almost anything.

I had this situation that only tiny part of my screen was still responsive. I wasn’t able to see most of the menu and settings sections, but at least I managed to see:

  • When my Kindle is awaken
  • When its menu is or isn’t opened up (I didn’t see many menu items though)
  • Which page of Settings I am currently at

This allowed me to figure-out a key combination needed to blind-reset my Kindle.

If your Kindle has a completely dead screen and you don’t see anything of above then sorry, this article won’t help you.

Turn off Bluetooth discoverability on Android devices

Some folks responsible for design and development of different Android versions or different UIs for this system must have some problems with their mental sanity, because they think that it is very funny to have your device discoverable to all surrounding devices whenever you only enable Bluetooth.

I don’t find it funny. Even more, I find it weird, bad and evil.

I had an issue with Xiaomi Redmi 6 phone, having MIUI 11 launcher installed. I find the regular way of turning off Bluetooth discoverability on this phone impossible and ended up with the need for installing some app.

This is a generic solution that may work in your case, even if you have some other Android gear, so I decided to share my experience here.

System interrupts kills PC / eats up to 100% of CPU

If your computer is suddenly slowing down noticeable and you have just:

  • installed a new driver or added new piece of hardware,
  • installed or started using some new hardware-related service (i.e. Internet phone, conference software)

then check Task Manager to see, if System interrupts isn’t consuming most of / all of CPU power of your PC.

Blaupunkt VCH601 for the seniors

I had to pick a handheld-hoover for my oldies. Due to their age, the actual weight of the device was an absolute priority. I decided to get Blaupunkt VCH601 — which seems to be unbeatable in this category (only 2.2 kilograms) — even though it turned out that it surprised me in some other areas.

If you think that a handheld-hoover description is far from IT and shouldn’t be published here then you may be wrong. Even IT geeks must clean up their rooms from time to time, sorry! :>

Dell Latitude 7290 keyboard backlight

Dell Latitude 7290’s keyboard’s backlight has a terribly short “on” period. It is set to 10 seconds only by default. Even on AC power. While industry standard is somewhere around 30 seconds or so.

This article shows how to resolve this issue in Dell Latitude 7290, but most other laptops and notebooks will most likely have a very similar solution — find in somewhere in BIOS.

Disable Bluetooth discovery in Windows 10

By default, when you enable Bluetooth in Settings app in Windows 10, your PC will become discoverable by all the nearby devices. But there’s a small (old good) Control Panel checkbox to control / disable this behavior. It is reported to be working in Windows 10 as well.

If you are 100% sure (see details in the following parts of this article) that your PC with Windows 10 is discoverable via Bluetooth even though you have turned such possibility off, then truly disabling Bluetooth discovery will require you to:

  • Tweak in Windows Registry or
  • Mess up with Windows API (through PowerShell console) or
  • Use some designated 3rd party Windows app that will do the trick for you

But, first let’s make ourselves sure that you really need to do anything.

Remove phone from “Your Phone” in Windows 10

I just wanted to get rid of my current phone in “Your Phone” app in Windows 10. But, since this is Microsoft and 25+ years of experience in making users lives as hard as possible, you cannot expect a simple “Remove” button. And there is no easy way to do this.

I’ve went through two different guides of removing phone from “My Phone”. None of them worked. I’ve ended up uninstalling “Your Phone” app (which itself wasn’t too easy task).

Allow WiFi access without revealing the password

Ever wanted to share your WiFi’s SSID and password among friends, neighbourhood or family members without revealing the password? Now, it is possible with a standardised QR code for that purpose.

It may look like this:

To get QR code like that, all that you have to do is to visit a service (or run a program) like for example Pure JS WiFi QR Code Generator (qifi.org — probably the most recognisable one), provide essential data (SSID, encryption mode, key, whether SSID is hidden) and hit the Generate button.

Free of charge and we love you, Evgeni Golov, for that! :>

At the bottom of the main page for qifi.org you’ll find the list of mobile phones’ cameras supporting WiFi QR codes. To update this information — starting with Android with Android 7.0, default photo camera (at least on stock Android in Motorolas) offers native support for such QR codes.

Error 777 and other problems using D-Link DWM-157 GPRS modem

If you’re getting Error 777 when trying to login your D-Link DWM-157 modem to a mobile network of your choice then the quickest solution is to disable automatic logon through 26006 (HSPA) mobile connection, It is added (and enabled) by default and apparently by mistake when installing drivers for this GPRS modem. If this doesn’t help or if you have different problems with this modem then you may also find help in this article.

This blog post focuses on D-Link DWM-157, but it may turn out to be useful for other D-Link mobile modems or for other GPRS modems at all, because it discusses the most popular issues when connecting to the Internet through GPRS USB modem.

Please, note that there is a certain amount of magic in this article. As you play with D-Link DWM-157 (or other D-Link modems), it quickly turns out that many things aren’t that certain as they were supposed to be.

Your Phone app: You can control a mobile device from Windows 10. Really?

Newest edition of Windows 10 (tested on 1903 edition) comes with Your Phone application that should — at least by its designers’ mean — ease your day-to-day management mobile device.

Unfortunately, it is still quite new, meaning — buggy. And the list of functionality is not quite long. In fact, you may have problems finding it usable at all or counting scenarios in which using this app is plausible.

The very introduction to Raspberry Pi

After a nearly five years of struggling with hardware and software for feeding data to Flightradar24, I have finally decided to give it a try with Raspberry Pi. On contrary to what some of you may think, this is not a guide on how to achieve it. The original text is very good and quite self-explanatory. No need to copy it here.

In addition to feeding data to Flightradar 24 there are hundreds of ideas how can you use your Raspberry Pi. With this article I wanted to show you (and remind to myself) just of a few IMHO most interesting ones.

If you’re just unpacking your first Raspberry Pi then better read these two articles:

Finding TP-Link router in your local network

Most TP-Link routers is accessible using admin/admin credentials under one of these URLs:

Of course, you must try to access these URLs from the computer or mobile that is connected (via cable or Wi-Fi) to the same local network, your TP-Link router is connected to.

If above fails and you don’t know current router’s IP address, you may try accessing:

URLs from the same local network, your TP-Link router is connected to.

Most TP-Link routers registers a virtual URL (like above) and you can access their control panel even without knowing their actual IP address.

Photos made with Galaxy J5 seems not rotated in IrfanView

There’s a known (yet very strange) bug in IrfanView, which causes photos made with Samsung Galaxy J5 (2016) to stay in original rotation. Since this occurs only:

  • in IrfanView (images are actually rotated and appears correctly in all other media browsers) and
  • only for photos made by Samsung Galaxy J5 (images made by other phones are unaffected)

this issue may simply be ignored by most of the users. However, I decided to write it here, as this seems to be an interesting (yet weird) IT issue.

HP LaserJet Pro M426fdn settings and factory reset

When running my HP LaserJet Pro M426fdn for the first time I didn’t removed touchscreen foil and my finger slipped over when selecting location of my printer. I ended up with having proper language but location set to Estonia and some reports (like Google Cloud Print configuration leaflet) printed in cyrylic.

Unfortunately, due to extreme stupidity of HP engineers you can only change language of your printer using standard configuration menu. But, in order to change location of the printer you have to perform a full factory reset of your hardware.

And here my problems started, because none of the solution I found seemed working on my printer.

Access website via IPv6 address

There are several ways, how one can access a website. Using domain name (i.e. http//www.example.com/) is one of most popular. We can also use IPv4 address (i.e. http://216.58.194.174/). In certain situations URL can be “enhanced” with port number, login and password etc.

A bit less known option is to access an URL using IPv6 address. You only need to enclose it inside square brackets i.e.:

http://[49d7::2e27:fe80:fe0d:d8ff]/webservices.html

Edit: Thanks to Foo Bar for correcting an obvious, yet fundamental mistake to this article.

Second life of burned-down DVDs (or CDs)

Default, system DVD burning program in Windows 7 is widely known for being very unstable and having burned-down (wasted, destroyed) DVDs ratio even as high as 20-30% (meaning, that you successfully burn only seven DVDs out of ten). If using more stable, dedicated software is not an option (for various reasons), you have to survive hell of using default burner. However, the fact, that DVD is burned-down doesn’t necessary mean, that you should recycle that DVD. In many case you can re-used in future.

This article started as a simple guide, on how you can re-use disk, that were damaged by native Windows burning software. But, since I was burning about 30 DVD DL files, when writing this text, I also included some tips and extra general information on burning disks and using UDF-formatted DVDs. So, this post may become useful even to those, who does not have any problems with disk burnout process under Windows.

Use custom ringtones in Microsoft Lumia phone

I’ve been struggling for hours to force my Microsoft Lumia 535 to display (and allow me to select) any .mp3 file as custom ringtone. Finally, this WindowsPhone.se answer solved my problems. However, there were some side notes and differences with my Lumia 535, that are not mentioned in this article, so I decided to write following post to further extend it.

Media supported by Samsung 50HU6900 4K TV

Three months ago I have purchased my first 4K / UHD TV — Samsung 50HU6900 — and after some time I tried to used the built-in media player to play some of my files. At the very end it turned out that — as in all Samsung devices — this is a piece of crap, full of some strange limitations. Finally, I have reverted back to my old, good standalone FHD player and I’m using Samsung one only for UHD / 4K files.

But, for all of you, that aren’t so reluctant, here is a list of media supported by this TV (and probably many more Samsung TVs) and all the limitations, you need to fulfill in order to have your media played.

Feeding data to Flightradar24 using DVB-T stick. Part 2. Software

You want to feed data to Flightradar24 using DVB-T stick and you have already received your hardware. Great. Now, it is time to talk about software, installation and configuration. Note, that (contrary to FR24) I’m providing information about Windows Vista and later editions of Windows. If you’re an old dinosaur, still using Windows XP or you need info for Linux, Unix or Mac systems, consult “Add Coverage” pages at Flightradar24.

IMPORTANT! Read this article BEFORE you even plug your DVB-T stick to spare USB port. If you do this, you’ll waste some additional time on uninstalling Windows drivers, which are completely useless in this scenario (since we want to receive flight data, not the actual TV signal, right).
