Sometimes our phone doesn't power on or gets
stuck in the logo. Technically our phone
is bricked. That means our smartphone due to software or a hardware problem, can no
longer function normally This usually happens when update attempt is interrupted. Installing custom ROM, apps from unknown sources or zip files
can also cause bricking. Bricks are of two types .
Hard brick
When the device generally doesn’t turn on or shows no signs of life it is said
to be hard bricked. Hard bricked smart
phone doesn’t power on or show start up logo. The main reasons for hard
bricking are installing custom ROM or installing zip file.
Soft brick
When the device usually
turns on and shows some signs of life it is said to be soft
bricked. Soft bricked smartphone generally gets stuck on the boot animation, or
keeps rebooting. The major reasons for soft bricking trying to root the
device or flashing the device.

Fix
If you ever get your device bricked try these fixes before taking it to the technician.
1 Press the Volume down , Power
and Home simultaneously( volume down+
power+home). If the phone boots to download mode then connect you device to
your laptop using USB cable. Using odin install the original firmware for your
device. You can download the firmware from www.sammobile.com/.
2 If the three button combination does not set
your phone to download mode then you can try this: fully charge your phone and
then switch off your device or remove the battery and place it again after that
smack you phone on any hard surface with
the side having power button facing the surface several times. Now switch on
the phone.
3 You
can download 300k tool and install it in your laptop/pc. After installing it
connect your device to the laptop with data cable and click the resistor icon. This will set
your device to the download mode. You can download this tool by clicking the link

4 If
the method given above don’t work then you can order USB jig online or buy it
from the stores nearby. Just plug in the jig into your phone and this will set the
phone in download mode within couple of seconds. A USB jig is a simple circuit
consisting of a 300K ohms resistance connected to a micro USB plug. A jig may
cost between $1-$3 when ordered online.
If USB jig is not available
nearby you or you aren’t able to order it online don’t worry you can make you
own jig.
To make a jig you require:
i) A micro
USB plug
ii) Resistor
(one resistor of 300k ohms or two resistor of 150K ohms each or three resistor
of 100K ohms each, you can add one 1k ohms in the circuit to compensate the resistance of the wires used)
iii) Soldering
iron and soldering wire.
Remove the plastic casing
of Micro USB by using knife so that the pins are visible. Make sure that the
pins remain intact.
Solder the resistors in
series to the pin no 4 and 5. (300k+1K
or 150k+150k+1k or 100k+100k+100k+1k) the total resistance should be 300k ohms
Remove the battery for
couple of minutes and insert it again
Now plug in the jig to the
device and within couple of seconds the phone is set into download mode.
It is hard to find the desired
resistance nearby so incase if you are unable to get the desired resistance you
can make your own variable resistance. For this you require:
i)
Two
paper clips
ii)
Pencil
iii)
Paper
iv)
Micro
USB plug
v)
Wires
vi)
Multi
meter
We all know graphite can
act as a resistor. So this idea is based on this. Rub the pencil on the paper making
a thin film over paper. Connect the wires to pin no 4 and 5 of Micro USB plug
and then to paper clips separately. Now insert the paper clips onto the paper
having film of graphite. Adjust the distance between the paper clips until you
get 300k ohms resistance or you can use multi meter to measure the resistance
if you have.
