on a Unisoc or Spreadtrum Android device using
reseaarch download tool.


In order for you to use this approach, you
need to have installed your Spreadtrum drivers,


I'll link to that in the description below.


You also need to have a pac file for your
phone model and you need to have research

and launch research download tool.


Next in research download tool, you load the
pac file.


You click on Load Packet, navigate to the
location of the pac file for your device,


highlight and click Open.


Wait while the pac file gets loaded.


Once the pac file is done loading, you'll
see the information listed at the top right


hand corner.


Next you click on Settings.


You're going to untick all items on this list
except FDL 1&2.


You click on Select all files.


That is going to uncheck everything except
FDL 1&2.


Next, you head over to the flash operations
tab.


You tick Active erase flash (under Erase Flash).


Now, you're going to enter the details for
the persist partition.


You can copy the information for that partition
by clicking active read flash at the top here


then you scroll down to persist.


You can double-click then you copy this and
you untick it (when done).


Now, you come back under Erase Flash, click
on this place.


Under base, you type persist and under size,
you paste the (size) information for persist


then you tick it.


Next you click OK.


Now, at this point, you click the Start downloading
button.


You power off the device and hold the boot
key.


It might be volume down or volume up depending
on your Spreadtrum or Unisoc device.


Once you're holding the boot key, you connect
it to the PC via USB cable.


Once that is done, you're going to have a
Passed message.

it up.
