It probably isn't bricked
I've got quite a few Arduinos, and over the last few years have only ever "bricked" one, and I think that was by zapping it with static electricity. Unfortunately that particular one had a SMD (surface mounted) processor chip, so it isn't easy to try swapping it with another chip.
Stay calm, and try the following steps ...

This is caused by a generic connection error between your computer and the Arduino, and can result from many different specific problems.
Here are some easy things that can often fix this error:
Disconnect and reconnect the USB cable.
Press the reset button on the board.
Restart the Arduino IDE.
Make sure you select the right board in Tools ► Board ►, e.g. ...

Know this is old but I ran onto it during my search for Nano(V3)'s not uploading so thought might help someone else. Problem is the bootloader - Arduino IDE BUT I Found an easy solution (right under my nose).
I realized that my nano's had been uploading just fine then I had finally updated the Arduino AVR Boards from 1.6.20 to 1.6.21. I didn't think ...

Another fix:
Change Tools->Processor->Atmega 328P to Atmega 328P (Old Bootloader). Remind that the Processor option is only available when you select some specific Boards at Tools>Board.
This worked for my Arduino Nano with CH340, using Arduino IDE 1.8.5 under Linux Ubuntu 17.10. Besides, this will probably happen if you use IDE 1.8.9 or newer ...

The problem is specifically pins 0 and 1. Although they can be used as regular digital IO pins, they also serve as the RX and TX pins for the Uno's serial port. The USB connection (for uploading sketches etc.) is routed to the same pins internally. Unfortunately that means anything connected on pins 0 and 1 can interfere with the serial connection, ...

At least - as I assume you upload your sketch via avrdude - please give more information about the upload failure (e.g. output of sketch uploader) so people here can help you better.
Additionally to the great answer of Nick Gammon, please search for exclamation marks in your sketch. If your sketch contains a string with more than or equal to 3 exclamation ...

Yes!
Its possible that you can upload a previously complied binary, using
AVRDUDE - a command line utility which is actually used to upload binaries, behind the arduino IDE.
You can find AVRDUDE in
Arduino folder > hardware > tools > avr > bin
This some documentation for AVRDUDE
http://www.nongnu.org/avrdude/user-manual/avrdude.html

Unfortunately, it can also mean that you burned your microcontroller. Were you doing anything dangerous right before you tried to upload a new sketch? Is the microcontroller still working, with its previously loaded sketch?

Arduino has recently changed to using a different bootloader on their official Nano boards that communicates at 115200 baud rather than the previous 57600 baud. Support for these new boards was added in Arduino AVR Boards 1.6.21. The new Nano board definition is not compatible with old Nanos and likely most 3rd party Nanos so backwards compatibility is ...

The clock speed selected will affect both delay*() and millis()/micros() as well as the functions in <util/delay.h>, therefore you must use the target system's correct clock speed if you are using any of these functions. This can be easily done by editing boards.txt and copying an existing entry for the Uno and changing the value of the f_cpu parameter ...

It's possible you have a non-fatal problem
check power
check connections
reflash the Arduino bootloader
If your Arduino has a socketed microcontroller you can try swapping it out with one that has the bootloader preloaded.

If none of the above steps work, try reinstalling Avrdude and the avr-gcc compiler. I had to do this after my Mega started suffering from this.
If you installed Avrdude and avr-gcc separately, simply uninstall them. if not, you may have to reinstall the Arduino IDE. These steps will depend on your operating system.

In my case I hadn't wired the RTS pin of the FTDI chip to a capacitor which went to the RST pin of the Arduino Pro Mini. Once I installed this connection, I no longer got the error and I was able to upload code.
Nick Gammon explains this in his forum.
I've added a picture of where/how the capacitor should be placed.

I've had the same message. Every time it has been solved by selecting the right port ie USB under the menu Tools then Ports. Its a simple step but I always forget. I'll unplug the Arduino to stop the current program, plug it in again to my computer to upload the new program and get the error, panic, curse, and only then, remember.

From the OSX System Report we learn that your board is based on an SiLabs CP2102 converter (or workalike), but according to your question you installed the drivers for an entirely different product from FTDI
(Arduino.cc has used FTDI in the past and CDC/ACM today, I don't believe they have ever used SiLabs so their instructions probably don't cover that, ...

After much frustration in trying things, I came across this forum post which advised:
sudo systemctl stop ModemManager.service
If this works, disable the service from starting next boot:
sudo systemctl disable ModemManager.service
It seems like setting ENV{ID_MM_DEVICE_IGNORE}="1" in a udev rule is insufficient.

Just hook up the pins (RX, TX, reset, Power, and Ground) to the corresponding pins on your Uno.
You may have to take the ATMega328 out of your Uno for this to work.
Keep in mind that you need to hook it up to the correct power pin! If your pro mini is running at 3.3v then you must hook it up to the 3.3 pin on your Uno.
Check out the ArduinoToBreadboard ...

Is there a way to compile arduino code without automatically uploading it, so that I can put the pre-compiled binary up for download on a website?
Yes, you can save the .hex file produced by the compiler. If you turn on verbose output from the compiler you can find the temporary directory where it is stored. Simply copy from there to a folder for download ...

I figured out a way to do this without having to port the compiler to iOS. It only works with the arduino Yún, but the Yún can send code to other arduinos with an spi cable.
Install an SSH app on your device so you can communicate with the arduino
Using that, install Ino on your Yún, a command line arduino compiler
Create a file, put your code in it, then ...

AVRDUDE does not actually perform the write, it merely directs it. The actual writes are performed either by the bootloader or by the ISP firmware/hardware within the MCU itself.
With the bootloader it depends on how itself is coded, but at worst it would finish off the flash byte or page or EEPROM page zero- or one-filled and then fail to communicate ...

It's hard to tell from your pictures, but are all the header pins soldered to the boards? If not, they need to be: there's no chance that the proper electrical connections will be made reliably if they're just inserted loosely into the holes.

ISP/ICSP has no role when utilizing a typical, properly functioning Arduino, as the program code compiled from sketches is instead downloaded via a bootloader (either serial, often behind an on-board USB-serial converter, or else directly USB).
The role of ISP in the Arduino ecosystem is mostly limited to:
Loading a bootloader into new chips which do not ...

This error message basically shows up for any communication problem, so by itself, it is not all that instructive. The Arduino Nano is supposed to have auto-reset, but maybe your clone does not? In that case, you'd have to press the reset key on the board just before starting an upload.

I had the exact same problem. I tried installing the IDE in another laptop and uploaded the program from that laptop. Problem solved. Then I came back to my laptop, uninstalled the IDE and re-install it.. it started working.
However, I wasn't satisfied because I couldn't find the source of the problem... so I tried running everything again the same exact ...

I think µProg – tiny, fast, portable AVR programmer with SD does what you want. You can store multiple files in the SD card (hex, eep etc) and select from the device menu which one to write to the target MCU without any need for a PC.
The best part is that it's available for free (PCB, schematic, firmware etc).
One of a kind, portable AVR programmer! ...

This error means that the program responsible for uploading (avrdude) can not communicate with your arduino.
Did you reset the board just before programming? The reset pin of the arduino seems unconnected in your picture; so the board wouldn't be executing the bootloader when the serial cables expects it to.
Try either to reset the board manually just ...

I can't guarantee anywhere in your city, but this hack will work pretty much wherever there is cell coverage for the carrier you choose.
You'll want the GSM shield.
Picture from Arduino
Anyway, it uses pins 2, 3, and 7 on it. It also has the ability to solder (on the bottom of it) a microphone and speaker connection. You'll need to buy a SIM card and ...

just to add to the list - some cheaper boards use CH340 chipset
here is a blogpost on how to install the drivers on OSX

From that post:
You can find drivers for this chip on the web site of the chinese manufacturer, here :

I've been searching through the net for some days, in order to discover how I could easily upload a sketch to an Arduino that is not phisically connected to my PC, but instead that is connected to an another one, that belongs to the same LAN. I mean:
PC1-SERVER
Arduino Uno is connected to this PC with classic USB cable.
This PC is running Ubuntu linux, and ...

Having a similar issue with my Sainsmart Nano.
Under Preferences check "Show verbose output during [x] upload, then when uploading, you should get a red trace like this:
