How to Boot Your Galaxy S10 into Recovery Mode & Download Mode
You don't need to be a hardcore modder to know the importance of booting your S10 into either recovery mode or download mode. In fact, these pre-boot menus are something everyone should be familiar with. The former can help you get out of soft bricks, while the latter lets you use utilities like...
android.gadgethacks.com
then go to "wipe data/factory reset"
after that reboot, and check if it works
if it doesnt then go again in recovery
and press, "apply update from ADB"
set up ADB on PC, and install samsung drivers if you didnt
connect phone to PC
put stock ROM zip in c:\ drive on computer for easier acess
and from command line in windows, type
adb devices
if it lists something, like your device, then you're good to go, if it doesnt work check adb and drivers to install properly (there is also minimal adb and fastboot available on xda, checkout that too)
then type this command:
adb sideload c:\stock_ROM.zip
and it should flash stock ROM via that
c:\stock_ROM.zip is path in your PC to stock ROM file
you can also try using SD card if you have one, put stock ROM in SD card, and instead of "apply update via ADB , you choose "apply update from SD card"
and i think, "apply update from SD card" will work with usb otg. juat buy usb otg cable for 2$, and usb stick. put stock rom zip in usb stick and it should work.
