01) Download a copy of your Main

02) Place that Main in Far\Plugins\jdflaser\2020_52

03) Drag the main into qamake.exe

04) Let it finish. It shouldn't take more than a few seconds.

05) Open Far Manager, press Alt-F1 and select "just da flasher"

06) Select as phone "db2020", maximum speed and click "jump down
into a large rabbit hole"

07) As soon as it connected select "bflash"

08) You will need to reinsert the battery 3 times (it will tell
you when to do that). Don't leave your computer.

09) As soon as it finishes, it will tell you to reflash your Main.
We're going to do that now.

10) In the right pane navigate to Far\Plugins\jdflasher\2020_52

11) Select your main (make sure you select the .mbn file and not
the .vkp file!) and click copy. In the 1st dialog don't change
anything, just click copy. In the 2nd dialog make sure "flash
babe image" (the 1st option) is selected and click flash.

12) After flashing is done, select the VKP patch that is in Far\Plugins
\jdflasher\2020_52 and press copy. Don't change anything on the 1st
dialog again. On the 2nd dialog make sure that "Process vkp patch"
is selected and click "flash". It should take a few seconds.

13) Now you can apply any patch you want!

14) After you finish, make sure you click the 3 dots ("...") and select "yes"

Next time you want to patch your phone, you won't have to do the same
things again! Before connecting your phone, select "qa2020" instead of
"db2020" as your phone model. Then click bflash and jump to step 13
