Q: Does the Samsung A20 FRP Unlock Tool delete my data? A: No. FRP is separate from your photos or contacts. However, if you did a factory reset to get the FRP lock, your data was already deleted. These tools only bypass the Google verification.
Q: Will this work on a Verizon or AT&T locked A20? A: Yes. FRP (Google lock) and Carrier lock are different. The tool removes the Google account lock. You will still need to enter a SIM network unlock code for carrier freedom. Step 1: Prepare the Locked Samsung A20
Q: I updated my A20 to Android 11 (One UI 3.1). Does the tool still work? A: Yes! As of writing, SamFw Tool v3.4+ works on Binary 6 (the latest for A20). However, if Samsung releases Binary 7 with a new patch, wait 2 weeks for the tool update.
Q: Is there an iPhone version? A: No. FRP is an Android/Google protocol. iPhones have "iCloud Lock" which requires completely different software (checkra1n, etc.).
