+# This helper script is made for wiping S50 7byte UID cards with Gen2 magic commands from restored state to blank one.
+#
+# Scenario:
+# You want to clone 7byte Mifare 1k card using RfidResearchGroup Proxmark3 RDV4.0
+#
+# Step 1: Dumping original card and making a Mifare 7byte UID clone using S50 7byte UID
+#
+# Place original card to the reader.
+# Dump data and recover keys
+#
+# hf mf autopwn
+#
+# You will get data, EML and key file. Backup this file, you will need them to wipe the card back to blank state.
+# Place blank S50 card to the reader.
+#
+# Get first line from EML file (block0) and write it down using command
+#
+#                             Place it here
+#                                    |
+#                                    |
+#                                    v
+# hf mf wrbl 0 B FFFFFFFFFFFF 046E46AAA53480084400120111003113
+#
+# Now restore all the data using built-in restore command
+#
+# hf mf restore
+#
+# Step 2: Recovering S50 7byte UID card to the blank state
+#
+# Find current card data files from Step 1 in your backup or if you lost them create them again using 'hf mf autopwn' command.
+# Place them in current working directory.
+#
+# Read hf-mf-CARD_UID-data.eml file and copy it content with CTRL-C.
+# Place it to the eml variable in this script.
+#
+# Check execution command and check device and command name: 'proxmark3 -c "%s" /dev/tty.usbmodemiceman1'
+#
+# Run script and review key blocks returning to default FFFFFFFFFFFF state.
+# Be patient! It is executing aprox 3 minutes.
+# Success one result looks like:
+#
+# Block 0: Success: isOk:01
+# Block 3: Success: isOk:01
+# Block 7: Success: isOk:01
+# Block 11: Success: isOk:01
+# Block 15: Success: isOk:01
+# Block 19: Success: isOk:01
+# Block 23: Success: isOk:01
+# Block 27: Success: isOk:01
+# Block 31: Success: isOk:01
+# Block 35: Success: isOk:01
+# Block 39: Success: isOk:01
+# Block 43: Success: isOk:01
+# Block 47: Success: isOk:01
+# Block 51: Success: isOk:01
+# Block 55: Success: isOk:01
+# Block 59: Success: isOk:01
+# Block 63: Success: isOk:01
+#
+# Thats it! Your S50 7byte UID card is wiped back. Now you can return back to Step 1 of this manual.
