Today, I will introduce you to black methods of Refund on electrical appliances. In fact, this is a very large field of your imagination and minimal knowledge of electrical engineering. But it's good that now we have Google, where we can easily find the information we need.
I will tell, for example, only 10 ways of black Refund of electrical appliances.
To begin with, familiarize yourself with several ways to ref USB devices - these are usually mice, keyboards, flash drives, printers, etc.
1. Software disabling
a) The easiest way to ref any USB device is to disable the driver of the USB device you want to ref. Insert the USB device into your computer, go to the device manager and look for your device, did you find it? Great, disable the driver. To demonstrate the serviceability of the port, you should connect any other USB device and show that the USB port is working. After that, connect our device to the same USB port.
b) You can also use the Acronis program and delete the device through it (with the possibility of subsequent recovery).
2. Clear nail polish, non-conductive.
It can be used, but it is not always the best solution, as it happens that the polish comes off when connected to tight connectors, and it is not very convenient to wipe it off afterwards. But you can still experiment.
a) Apply a thin layer to your finger to show that the fingerprint scanner does not work on your new iPhone.
b) The most common use of clear nail polish is to smear a thin layer on the contacts on the SIM card, insert this SIM into a newly purchased phone and show that the SIM card slot is not working. After that, discreetly wipe this polish from the SIM card, dip your finger in solvent / nail polish remover, wipe the SIM and insert it into your phone to demonstrate the functionality of the SIM card.
c) Coat the battery contacts or on the phone itself with an even layer. Accordingly, power will not be supplied.
4. Short-circuit the contacts.
a) Short-circuit the USB ports between themselves, for example, if you are refurbishing a laptop or motherboard. The front terminals have one data bus, so by short-circuiting one port, you will also cut off the second one.
b) To do this dirty trick, we will need a small conductive material, the best solution is to use a piece of aluminum foil. We close the central DATA contacts. After this manipulation, the computer will not read the data, but it will be visible that the power is supplied. Using the flash drive as an example, the LED blinks, but there will be no reading.
c) Conductive glue, varnish can be made at home, but if your finances allow you to spend 500 rubles, you can buy it at any radio electronics store. There are also other conductive tools - a marker, pen, pencil, spray.
5. Upgrading the surge protector.
a) Disassemble the surge protector, it is advisable to take the cheapest one with conductive parts. Bend one "whisker" away from the phase/zero, it makes no difference, on the second "whisker" you need to install heat shrink and expose the contact in the middle. The idea is that when we need power, we connect the plug from the side of the exposed part, if we do not need voltage, we connect the plug from the side of the heat shrink. I tried to draw)
b) Give power to the surge protector diode separately (provided that you have exactly this extension cord with a diode that lights up when switched to the ON position). Connect a battery, which, when the contacts are closed, will supply power and the diode will light up when in the ON position, even without a network. To be sure, you should connect another power source, for example a lamp, to another slot of the surge protector. Disassemble the lamp and perform the same manipulations as with the surge protector, namely, give power through the battery to the lamp. Be sure to connect the remote control to turn on the lamp. There should be no power from the plug to the lamp! And with the help of another person who will stand at the “machine” and turn off the power to the entire apartment at the right time, do the following manipulations. You show the initially turned off power filter on camera, next to you is a lamp, a charger, the product with which you do this procedure and another device, which is needed to show that another device is charged from this charger. Turn off the machine in advance and start shooting a video. Turn on the power filter (the diode should light up from the battery), insert the lamp plug (at this time, your friend turns on the lamp via the remote control). The lamp should light throughout the video. Insert your “faulty” device into the power filter, demonstrating the malfunction of the device. After that, we connect another device from the same charger (at this time, our friend turns on the “machine” so that power is supplied to the power filter). We show that the charger is working properly. We turn off this device and demonstrate the malfunction again (accordingly, your friend turns off the “machine”). For persuasiveness, at the very end of the video, you should turn off the lamp from the network filter and in parallel, your friend turns off the lamp from the remote control.
6. I consider using a soldering iron to be the most effective method.
After all, if you unsolder + or - from the device, it will no longer work properly. Here you just need to practice working with a soldering iron, so as not to damage our device. What to unsolder is up to you, because everything depends on the specific device and your goal. Each device (phones, hard drives, sata, flash drives, etc.) has channels in the pinout data + / - and GDN (ground). You just need to carefully place a drop of solder or wires on these 2 inputs, as a result of which it will not charge, be detected. You can upgrade the power supply, make a switch on the 12V line, but for this you should study the topic well. You can bite off the capacitors, solder on the connector. And again, everything depends on the device, look at the diagrams and act.
7. Connecting wires.
a) Take a long wire, for example dvi, hdmi, a switch is mounted in the middle of the wire. Just turn off the power at the right time.
b) Take the male-female wires and disconnect/connect them at the right time.
8. Disassemble and disconnect the phone screen/laptop keyboard cable, etc.
9. Wireless networks.
a) For example, how to ref MI band. Everything is quite simple, the MI band is linked to a third-party phone, and when recording video evidence, you will not be able to connect it to your device.
b) Create interference with wireless networks using signal suppressors (jamming). This device is prohibited by law in all CIS countries, but you can try to assemble it yourself instead of buying it, fortunately, there is enough information on the Internet.
10. Substitution of the IMEI of the phone, put ROOT rights, change the IMEI, pack it back.
We say that we are afraid to use this phone, the Chinese wants to set you up for a criminal case, etc. By the way, this manipulation is also prohibited by law.
I will tell, for example, only 10 ways of black Refund of electrical appliances.

3. Transparent tape, use it for the same purposes as nail polish.
