TodayI tried to flash stock ROM of galaxy A21S and got a failed message in Odin, after that I rebooted the phone to try another time but I am unable to enter the download or recovery mode and the phone doesn't start. Whenever I try to start the device or boot to download mode it keeps rebooting itself with a note on the upper left of the screen showing "TAG LOCK is not set". I have tried all the key combinations and also tried keeping volume button pressed while connecting it to the computer but it doesn't help. Please help how to get rid of this.
I am not that newbie to flash ROMs. I have flashed multiple times on multiple devices of almost every company handset. I have bricked many times but fortunately able to reflash the stock ROM almost everytime. But this thing happened to me first time that I can't enter download/recovery mode. In other devices ADB works even if it's bricked and in this case Samsung's download mode. But thanks for your reply and time, I'll try once again. I also lost my bill/warranty card and this is why I haven't visited service center. P.S : it's not my primary driver.
