I'm not an expert but did you try to start by checking the components on the USB flash drive to see if something was obviouse damaged or did you just "decided" to do a chip-off recovery without attempting to figure out if you could repair the USB stick ?
Well,
This is what i did .
1 : Removed The Plastic Cover And Inspected The Entire Drive Each Leg of Both NANDS And Main Controller And Main Connector For Any Dry Solder Or Solder Breakage Due To Any Force Specially Near The Connector
2 : Traced The Main Voltage 5V And GND To The Controller Via All Components Specially Checking ZERO Ohm Resistors And Any Other Fusable Resistor .
3 : Did Not Check The Crystal This Time ,Though Its Nice To Do It Via a Scope For Sinewave Frequency As Per Its Marking
4 ; The Drive Would Get Detected In The Computer With No Capacity ,Hence Decided To Chipoff
