### How to get into bootloader shell?
If you can't interrupt the boot sequence with a key combination, or if your
camera requires a bootloader password that you don't know, you can still make
it stop the Linux kernel booting and throw you into the shell.
The first thing to do is locate the flash memory chip on the camera circuit
board. Typically this is a square chip with 8 pins labeled 25Q64 or 25Q128,
rarely 25L64 or 25L128. If you have trouble locating the chip, try taking
some pictures of your board from both sides. Then ask for help
[in our Telegram channel](https://t.me/openipc).
__Do not try to short-circuit any random chip! It will most likely burn your camera circuit.__
Short-circuit pins 5 and 6 of the flash chip with a small metal object,
a screwdriver or tweezers, right after the bootloader starts but before it
calls up the Linux kernel.
Pins 5 and 6 of the SOIC8 chip are on the opposite corner of pin 1, indicated
by the embossed or drawn dot next to it.
