As
the flagship variant of Sony Mobile, Xperia series smartphones termsuk
successful in the world market. Homeland in the smartphone market, sales also
included nice. Thus, as a technician, we must be prepared to face this Xperia
type damage.
On
this occasion, VTIGA HP and Laptop Technician Course will discuss how
improvements Sony Xperia Z1 dead C6903 total.
Repairof dead phones total required precise and accurate analysis. If we only try to
guess the location of the damage, the results are often unsatisfactory. How do
proper analysis? Must necessarily follow a standard repair procedure. And
always begins by checking the current usage of the mobile phone. The process of
checking the flow, enough to power supply 1 A
By
connecting the output of the Power Supply connector to the mobile phone
battery, and set the output voltage of a power supply of 3.7 volts, we can see
the large current into the cell phone from his Ampere meter. In the picture
that was shown by the meter at the bottom of the Power Supply. Of the current
consumption is read, we can determine the location of damage.
Back
to the case of the Sony Xperia Z1 C6903 brought the student, slightly above the
current consumption of 100 mA. From here we can know that, IC power is already
working. To determine whether the CPU it can work or not, the phone trying
recharged using Flash software tool. If the CPU can not be detected at all. The
process is continued by analyzing its hardware parts. Among the most important
is the working voltage required by the main chips such as CPU, eMMC etc.
However,
if the CPU phones are still detected, corrective measures followed by filling
the firmware into the phone. Expected after the process is complete, the phone
back on. However, not all cases of damage as simple as that, there are also
many, after the charging process is complete, the phone still will not turn on.
Such cases are often termed mobile experience 'bricked'.

Run the tool S1
In
the emergency phone type select mode
3.
Then click the button flash
Navigate
to the folder firmware for C6903 that we downloaded
4.
Once it is still on the S1 Tool click on the button "test point
ready" and make sure the device manager has been detected "SEMC
FLASH" during a test point earlier
5.
After that wait until the process is complete, after it to make sure, turn the
device off and hold vol - and connect it to the PC, when it is detected
automatically, then it's a success. Furthermore, we stayed flashing using
Flashtool or using Sony PC companion
After
flashed using Flashtool, the Sony Xperia Z1 back to normal.
