Can we rooting using adb sideload from original samsung recovery? My Device Samsung SM-T211 and SM-T11.
If you want rooting your device download supersu from the official thread on XDA supersu thread
but if you have android 6.0+ you can install magisk instead magisk thread
You can't root your device with samsung recovery, you have to flash a custom recovery (it avoid the warranty) like TWRP and then you can install supersu/magisk
