Wipe user data partitions safely if standard recovery menus are inaccessible. Safety Guidelines and Troubleshooting
Samsung M017F , commercially known as the Samsung Galaxy M01s
After analyzing the mainboard schematics (PCB Rev. 1.0) and practical reverse engineering, the verified ISP pinout for the Samsung M017F is as follows:
: Move directly to the User Area Partitions or Special Task menu tabs. Select Clear FRP or erase the persistent lock partitions ( frp or persistent sectors).

Interacting directly with the device's storage chip via ISP will void any existing manufacturer warranty. Data Loss:

Once the hardware connection is secure, open your preferred eMMC software module on your PC (e.g., UFI Android ToolBox or EasyJtag Plus Emmc Tool Suite). 1. Detecting the Storage
Power supply pins (usually 2.8V and 1.8V). Technicians often use a USB cable for power instead of soldering these to avoid damage. Ground connection to complete the circuit. Important Precautions Wipe user data partitions safely if standard recovery
For three hours, Jae mapped the constellation. He discovered the M017F had a trap: the manufacturer had swapped the traditional DAT0 and DAT1 pins, a silent ambush for any hacker following old Samsung schematics. Worse, the VCC pin was flanked by two "decoy" pins that, if probed simultaneously, would trigger a self-destruct fuse, melting the internal bootloader.

To perform ISP, you must connect to five specific test points on the motherboard. These correspond to the standard eMMC interface:
