Things needed before the flashing:
- USB data cable
- MediaTek USB VCOM drivers
- SP Flash Tool (v3.1206.01 or higher for MT6575 / v3.1222.00 or
higher for MT6577)
- The Right ROM File from your phone vendor
The tutorial:
- After, make sure that you have MediaTek DA USB VCOM drivers
installed.
- Then in order to flash when you plug in your phone to PC in power
off state….you
see a message on your PC, Looking for Drivers “MediaTek MT65xx
Preloader”
- Just go to device manager when you see that message….say install
drivers manually
and give path tousb2ser_Win7.inf (or
other OS) to install the driver.
Flashing the whole ROM
First of all open
SP Flash Tool,
then clickScatter-loadingbutton to load the correct scatter
file (MT6575_Android_scatter_emmc.txtorMT6577_Android_scatter_emmc.txt,
depending on
which phone you have) for your device and ignore any message that
may appear.
Turn off your phone, remove the battery and replace it after some
seconds (and don't turn onthe phone).
No need for any Fastboot mode, just plug in your phone to PC with
USB cable inpowered off state for next step
Press F9 (or hitDownloadbutton) and connect your phone into
the computer via USB datacable. The process will start and a red progress bar
will appear.
(You might actually see “Looking for MediaTek MT65xx
Preloader”drivers at this step as well…just follow the same step asbefore
to install the VCOM drivers and the flashing process will start)
After the red progress bar is complete, there
will appear a purple progress bar.
Right after the purple progress bar is complete, a message will
appear underneath it: “
Pleaseinsert USB cable in x seconds”and then the download will start right away
(you will see the yellowprogress bar filling up).
When the yellow bar is complete, you'll get a popup with a green
circle and
DownloadOKmessage,
which means that the process has been successfully terminated.
You can now safely disconnect your phone and
turn it on. The process ends here.
Flashing only part with Recovery.img
·
In case you want to
flash just one part of the ROM, that is also possible. In the shown example,
only recovery image will be flashed. Deselect all parts except the one(s) you
want to flash and then press F9 (or hit Download button
·
The tool will immediately show
a warning because not all parts are selected, but you should continue anyway.
Safely press Yes to continue.
The download of the chosen partition image will start and after
the yellow bar is complete, the popup with the green circle should appear.
Note that, even though it isn't mandatory to select it on the
list of images to flash, preloader file must be present in the same folder as
the other partition(s) that you want to flash, or else phone will not be able
to enter into download mode.
