How to Flash Samsung Galaxy S20 Plus

Although the actual process of flashing the Galaxy S20 Plus itself is not difficult, my friend who wants to try it must be more thorough because if one chooses the firmware it can be that your cellphone cannot be turned on again, or commonly referred to as bootloop.

For this reason, you have to be careful in choosing the firmware, pay attention to the type of cellphone owned by your friend, and adjust the firmware to be downloaded to flash. And if you try a custom ROM, then consider first the comments of people in the forum who have tried it, whether the comments are positive or even negative.

Before you do flashing the Samsung Galaxy S20 Plus, it is better to prepare the following materials for download

If when the flash is finished, your Samsung Galaxy S20 Plus phone has bootloop, so try to do a factory reset in recovery mode. The first way is to open recovery mode (turn off the phone and press and hold the Home + Power + Volume button up).

Then after entering recovery mode, select Wipe Data / Factory Reset. Then restart your cellphone and wait.

An additional magnitude, for now, the flash process can only be done with a PC, to flash a version without a PC alias via sd card and TWRP, this is still not possible.


That’s the way to flashing the latest Samsung Galaxy S20 Plus and it’s easy to do even for friends who don’t have experience in flash though. And if you have finished the flash, you can try to root Galaxy S20 Plus. See you in my next article.
