The phone does not enter the "Download Mode" and "Recovery" mode. What to do? Restore the phone from the state of "Brick"
If during unsuccessful flashing or during power outage during flashing by Odin program, as well as after unsuccessful update via Fota or Kies, the phone stopped turning on and the 3-button mode does not work, then the recovery instruction is for you.
You can transfer the smartphone to the mode "Download mode", which has just such a picture:
For this: buy a micro-USB plug type B, or a cable with such a plug.
Attention: Check that pin 4 in the cable is connected. It is not used on some cables. Next, you will need a resistor with a resistance of 301 kО© (you can use two resistors connected in series with 300 kО© + 1 kО©). It is advisable to use resistors with a minimum tolerance (the more accurately, the better).
A resistor (or pair) is soldered between pins 4 and 5 of micro-USB type B.

So let's get started.
1. Turn off the smartphone and remove the battery for 5 minutes, insert the battery back. Do not turn on!
2. Insert the manufactured or purchased plug into the phone jack. It is advisable not to touch the resistors, as the skin has its own resistance.
3. After a few seconds, the device will go into download mode (Download mode). Do not press the power button!
4. We take out the plug, insert the USB cable from the PC and flash the necessary firmware using the Odin program.
