reMarkable 2 Recovery / Unbricking

Tools for recovery (works only under Linux)

Parts and prerequisites

To put the rM2 in recovery, you will need:

• USB-C breakout board

• Pogo pin adapter to usb the pogo pins are as follows, when viewed from the side, device facing up (VBUS is near the usb-c) GND,ID,D+,D-,VBUS

• imx_usb_loader a binary is included, but feel free to compile it

Guide

• run dmesg -w on your host to monitor
• power off the device
• connect the USB-C breakout board
• pull down B8 (connect B8 over a 10K resistor to B12)
• connect the pogo pins to the tablet and to the host usb
• make sure the connection is good, use a short good, different cable, etc
• if the device does not start on its own, press the Power Button
• you should see a new device USB HID v1.10 Device [Freescale SemiConductor Inc SE Blank ULT1]
• remove the pulldown resistor (disconnect B8)
• run sudo ./imx_usb or add the udev rules to use it without sudo
• should see USB Mass Storage device detected
• should see a new mountable block device

Next steps

• to recover the ssh password, mount the home partition grep Developer <mountpoint>/root/.config/remarkable/xochitl.conf
• TODO not tested, but something like dd if=raw of=/dev/mountedroot1
