Hello, thank you for help me hrad reset, but when I learned about frp, I found that they are also difficult for the Samsung a21s. I am using Samfw v 4.9.1, but the error below keeps showing up, I ever device on while the program is running. program Unlocking step 1... OK Waiting device reboot. Do not unplug the cable Unlocking step 2...Error when sending command The port 'COM4' does not exist. Error when send command The port 'COM4' does not exist. Error when send command The port 'COM4' does not exist. Error when send command The port 'COM4' does not exist. FAIL
@@azamteach7173 I know about these 2 tools but can't use . These 2 tools are quite expensive for a device repair. I'm thinking about flash Odin for the device in the hope that the device will no longer have frp.
