fixed : reset password on QD520 IP-camera without a Windows-PC [Mac-only]

Question :

A friend donated a QD520 IP-securitycam to me. It looks great and from what I’m reading, I should be able to get it working with Mac-software, but I when I try to access the device in Safari, it asks for a password (that my friend couldn’t remember), so I can’t login…

There’s no reset button on the QD520, so I will need to reset the password with special software, but it turns out that that software is Windows-only, and I only have Macs…

What can I do ?

 

Answer :

You are completely right about the Windows-only software… but I managed to port the reset tool to Mac using WineBottler, and using that, you can reset the QD520 and it’s password back to factory settings.

After the reset, the QD520 will be back to these factory settings :

login = admin

password =               [ BLANK / NOTHING / EMPTY ]

IP (static) = 192.168.1.10

interface language = (simplified) Chinese     [ yep, that’s a very uncomfy downside of resetting… unfortunately ]

 

Here’s how to reset the QD520 :

  • connect the QD520 to your network
  • use the free LANScan.app (or something similar) to find the QD520’s current IP address [ the LANScan app can be downloaded for FREE from the Mac App Store ]
  • download Winebottler here, and use it to run the Windows-only version of the PasswordResetTool you can get here or in this Xmeye Camera Software bundle (or use Winebottler to create a Mac-compatible version of the QD520passwordresettool)
  • as the original Windows-version PasswordResetTool needs a Telnet connection to communicate with the QD520 IP-cam, you now have to enable Telnet (or Netcat to be more precise) to it’s IP address on your Mac as follows :
    • on your Mac, go to Applications –> Utilities –> Terminal.app
    • double-click on the icon to run Terminal.app
    • there you will see your username-with-a-dollar-sign-attached-to-it ; immediately after that, typ this :
    • nc xxx.xxx.xxx.xxx 23
    • so : N C space QD520-IP-address space 2 3 (in which 23 is the Telnet port number)
    • now you will see an ‘answer’ in the Terminal.app :
      • ????????LocalHost login:
  • when you see that text appear, doubleclick on the QD520passwordresettool to run it
  • when it’s open, at “Device IP”, fill in the QD520-IP-number, and click the “Reset” button
  • when you get the feedback message “Reset OK, Waiting for reboot your device, please!”, click the “OK” button
  • that’s it !
  • don’t forget to quit both the QD520passwordresettool and the Terminal.app

enjoy 😉

NOTE #1 : as mentioned before, the QD520’s IP address will now be 192.168.1.10 and the interface will be in Chinese unfortunately, however, you will be able login now ! ( using login = admin / password = [empty] )

NOTE #2 : unfortunately, there is no Mac-friendly solution to change the QD520’s settings like IP-address and Password just yet… for that, you will still need to use Internet Explorer for Windows with ActiveX and JAVA Runtime installed… [ we are working on a solution for that, but as ActiveX is not supported on Intel-Macs, that’s an extremely hard nut to crack and might even be too complicated… ]

fixed : how to reset RT3 car navigation system

Question :

I have an old Peugeot with what-once-was a state-of-the-art navigation system : an RT3 car computer by Magneti Marelli. When trying new navigation CDroms, I encountered an error. The dealer says can it should be fixed by a restart of the RT3 car computer by doing a “Dark button”-reset.

However… no-one seems to be able to tell we where that mysterious “Dark button” is located…

Can you please help me ?

 

Answer :

There are two ‘official’ reset options for your RT3 car navigation system :

option #1 :

press the DARK-button until the screen goes black and the RT3 then restarts

Note : the DARK-button is not some mysterious unmarked button, it’s simply the button marked “DARK” that is normally used to darken the screen to not shine too bright at night

option #2 :

  • turn off your car and take the car key out
  • unscrew the Torx10-screws that are hidden inside the two tiny holes next to the “MP3” and “GSM” printed text (note : the screws don’t come out, the just come loose and stay inside the panel)
  • pull the menu-wheelbutton to slide out the ‘car radio’
  • flip open the metal lid that is just above the big barcode sticker
  • take out the yellow battery pack
  • unplug the white connector that is halfway the battery pack’s cable
  • wait one minute
  • plug the white connector back in, but the battery pack back, close the metal lid, slide the ‘car radio’ back in and tighten the Torx10-screws

According to the Peugeot mechanics, option #2 should work if option #1 doesn’t…

Good Luck !

fixed : deleting photos to free up memory on your iPhone

Question :

I have a 16GB iPhone running iOS10, and it freezes whenever I want to take a photo… I get an error message that there’s no memory left on my iPhone so I can’t continue…

I checked and it turns out that I have literally 1KB (yes, only 1KB, not even 1MB…) left as free memory… and most of my 16GB is occupied by Photos.app (about 12GB)…

How do I free up space without deleting valuable photos and videos ?

 

Answer :

The best way (if not the only) to free up space on your iPhone will be to delete a lot of photos and videos, in your case. The way to do that without running the risk of throwing away photos and videos that you would have liked to backup it this :

  • connect your iPhone to your Mac using a USB-cable
  • open the Photos.app on your Mac
  • click on your iPhone, which is listed on the left side
  • now, in the main window, go to the photos that are displayed as ready to import (photos that aren’t on your Mac already are automatically filtered out by Photos.app
  • from that selection of (un-imported) photos and videos, select ONLY those photos you want to keep
  • import that selection onto your Mac
  • first check if all photos and especially all videos (as those are not being transferred automatically through iCloud syncing) you selected have been imported
  • then unplug your iPhone’s USB-cable
  • then delete all video’s you can, and if that isn’t enough, delete all photos older than about one year from your iPhone
  • Please, note that iCould will only contain the most recent photos (usually not the videos)
  • now, restart your iPhone by simultaneously pressing the two main physical buttons : both the menu-button (just below the screen on the front side) and the ON/OFF-button (top side or right side)
  • then check if you have enough free space on your iPhone now
  • if not, delete more photos from your iPhone (in the way explained above)
  • …then restart your iPhone

fixed : trackpad not responding when clicking

Question :

I had left my MacBook Pro (Late 2008 running OSX 10.11 El_Capitan) running and had forgotten all about it… after completely recharging everything seemed to be okay on first sight, but it turned out that even though I could use the (internal) trackpad to move the cursor, I wasn’t responding at all to any clicking on it. I therefore had to connect a USB-mouse. Even after restarting, the trackpad was responsive to moving the cursor, but not to clicking…

Is my MacBook’s trackpad broken ? Or is there a software solution I could try ?

 

Answer :

Even tough it’s not possible to completely rule out the scenario that your trackpad is broken, chances are you will be able to get it working properly again by an action that is normally referred to as “Resetting the PRAM”. Here’s how to do that :

  1. shut down your MacBook
  2. take out all cables and USB-sticks (this is just to rule out complications)
  3. restart your MacBook using the POWER-button
  4. immediately press and hold the key-combo [CDM]+[ALT]+[P]+[R]
  5. make sure you do so while the screen is still black
  6. when the screen lights up in light grey, you’ll hear the startup-chime
  7. now release all your fingers from the keyboard before the Apple-logo appears
  8. let your MacBook startup fully, then test if all works as expected
  9. then reconnect any cables and USB-sticks needed

Note : no worries if you act too slowly or too quickly ; if you are too late to press the key-combo, just let your MacBook startup, then shut down and try again ; if you keep pressing the key-combo for too long, you will hear the startup-chime multiple times (you will have reset your PRAM multiple times, but that’s no problem) so just release the keyboard, and just let your MacBook startup and you’re done… 😉

fixed : Xiaomi Mi Band Pulse seems bricked or broken

Question :

As I was fiddling with connecting to a bluetooth speaker, the connection to my Xiaomi Mi Band Pulse suddenly vanished. Even though my iPhone can still see the Mi Band, but it says “Can’t connect to band” and on manual retry connection cannot be established due to a time-out error. In Bluetooth Preferences the Mi Band is visible, but not connected, and on manual retry I also get no connection due to a time-out error.

Is my Mi Band bricked or broken ? If not, what is the right way to reconnect my Mi Band to my iPhone ?

 

Answer :

You are probably in luck as even when your Mi Band seems bricked or broken, is most of the time just hangs and can be fixed doing a reset.

The reset & reconnect procedure in short :

  • switch-off Bluetooth
  • reset the Mi Band
  • reboot your iPhone
  • switch-on Bluetooth
  • reconnect via Bluetooth

That probably isn’t enough info, so here’s a step-by-step walk-through :

  • on your iPhone, swipe-up from the bottom of the screen to get the ‘underwater’ Settings pull-up panel
  • click on the Bluetooth-icon in a white circle, which will then turn grey, indicating Bluetooth is OFF
  • now take the sensor-pod of the Mi Band Pulse out of the bracelet and put it in the refrigerator (yes, the one in your kitchen, but not in the freezer)
  • leave it there for at least one hour (officially that should be at least 4 hours, but experience shows that only one hour will also do most of the time…)
  • first, do a reboot of your iPhone by pressing the MENU- and ON/OFF-buttons at the same time until the screen goes black and a white Apple-logo is displayed [ NOTE : for some iPhones the reboot procedure (a.k.a. “hard reset”) is slightly different ; more info can be found here ]
  • when the iPhone comes back up, type your access code to unlock your iPhone
  • then swipe-up from the bottom of the screen, and in the pull-up Settings panel, click on the Bluetooth-icon in a grey circle, which will then turen white, indicating Bluetooth is ON
  • and open the MiFit-app on your iPhone
  • then, take the Mi Band sensor-pod out of the fridge and plug it in the Mi Band-charger cable and put the USB-end into a USB power adapter (a powered USB-port will also do most of the time)
  • now be quick : only during the blinking of a LED on the Mi Band sensor-pod you have the opportunity to reconnect !
  • while the LED blinks, in the Mi Fit-app, in the Status view, click on reconnect to re-establish the Bluetooth-connection between Mi Band and iPhone
  • if all orange-collored texts are gone from the Mi Fit-app, you have successfully reconnected, if not : just unplug & replug the Mi Band sensor-pod, try again and make sure you act quickly
  • everything should now work properly ; enjoy !

If you can’t get it to work using the above procedure, just try again. And if that still doesn’t help after several tries, try these versions of the procedure, in this order :

  1. try again, without putting the Mi Band sensor-pod in the refrigerator
  2. try again, exactly as described (so including the refrigerator procedure)
  3. try again, now keeping the Mi Band sensor-pod in the fridge for at least 4 hours
  4. try again, now keeping the Mi Band sensor-pod in the fridge overnight
  5. try again, but start with deleting the MiFit-app from your iPhone, and reinstall it after reboot
  6. try again, exactly as described

You probably have things up and running by then, but if you’ve done all this and it still doesn’t work, your Mi Band sensor-pod is probably broken and you should contact your reseller for a replacement…

Good Luck & enjoy !

fixed : old hard reset procedure doesn’t work on new iPhones with finger scan

Question :

I just encountered an error (or bug) in iOS forcing me to do a hard reset on my iPhone, but when I try the good-old reset-procedure by pressing both the MENU- and POWER-button simultaneously, there’s no reset… just a click-sound and a screenshot photo being taken…

What’s going on ?

 

Answer :

For all iPhones (and iPads) that still have the MENU-button (*) without fingerscan [ so all iPhones up until and including the iPhone 5 and 5c ], the procedure for a hard reset is :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the MENU- and POWER-buttons (*) of your iPhone/iPad simultaneously until the entire screen turns black and the Apple logo reappears
  • then release both buttons and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

…that’s it

For all iPhones that have the new fingerscanning MENU-button (*) [ so all iPhones starting from the iPhone 5s and iPhone 6 and newer ], the above procedure does no longer work, so there is a new procedure for a hard reset :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the POWER-button (*) until the screen goes fuzzy and the ‘slide to power off’-slider appears
  • then release the POWER-button and slide the slider to the right to turn the iPhone off
  • wait for the screen to go black
  • then press and hold the POWER-button until the Apple logo (re)appears
  • then release the POWER-button and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

UPDATE : since iOS 9.3 the ‘old’ procedure for a hard reset was re-introduced as an extra for the newer fingerscanning iPhones, so these can now also be reset by simultaneously pressing & holding the MENU- and POWER-buttons 

…that’s it

(*) the MENU-button is the button that is on the front side of your iPhone or iPad just below the screen :

  • on iPhones up until the iPhone 5 and 5c, the MENU-button has a ’rounded square’ icon on it
  • on iPhone 5s, iPhone 6 and newer, the MENU-button has no printing on it, but it has an (invisible) fingerscanning-sensor inside

…the POWER-button is the button that is used to turn the iPhone/iPad screen ON and OFF :

  • on iPhones up until the iPhone 5c and 5s, the POWER-button is on the top-side of the iPhone (just like it is on iPads)
  • on iPhone 6 and newer, the POWER-button is on the right-side of the iPhone

fixed : no audio on iPhone, just an annoying beeping noise

Question :

Today the output-sound of my new iPhone 6s turned into complete noise. No matter which app I use, be it YouTube, iTunes Music or online TV, all sound is reduced to an alternating beep-sound. I can turn the volume down (or up), but it doesn’t go away, no matter what I try…

What can I do ?

 

Answer :

Regardless of the exact cause of the error you run into… your best option when encountering weird behavior of your iOS-device (iPhone/iPad) is to do a reset.

For your audio-problem this is tested and proven to work also.

For the iPhone 6s the reset-procedure is a little different from the one used on previous iPhones (*) :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the POWER-button until the screen goes fuzzy and the ‘slide to power off’-slider appears
  • then release the POWER-button and slide the slider to the right to turn the iPhone off
  • wait for the screen to go black
  • then press and hold the POWER-button until the Apple logo (re)appears
  • then release the POWER-button and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

…that’s it

😉

 

On previous iPhones the reset-procedure is :

  • make sure you have the PIN-code of your SIM-card at hand
  • press and hold the MENU- and POWER-buttons of your iPhone/iPad simultaneously until the entire screen turns black and the Apple logo reappears
  • then release both buttons and wait for the screen to go back to normal
  • and when asked, enter the PIN-code to unlock your SIM-card

…that’s it
