How to enter flash mode
Installation
An original Kobo Clara 2E SD card or a copy (e.g. via dd) is recommended. The unpartitioned space at the beginning of the SD card contains the E-ink panel waveform information. This information is device batch specific and is copied to /lib/firmware/imx/epdc/epdc.fw on boot.
Replacing internal µSD Internal µSD card can be replaced by something bigger.
A recommended practice to install software is to clone the SD card and keep the old one as backup or have at least the hidden waveform partition in place. before doing pmbootstrap install
So basically pull out µSD and connect to your PC and do:
dd if=/dev/sdX of=clara2e-backup.img
replace with something bigger (in reality only the waveform is needed but for simplicity) and do:
dd if=clara2e-backup.img of=/dev/sdX
and then use that sdcard with pmbootstrap install --sdcard
Variants A/B
There are two variants of the device differencing in the PMIC used for the display. A has SY7636 and B has JD9930. The latter does not store the Vcom voltage needed contrary to the chips in the other ebook readers which all store the volatge non-volatile. The voltage differs a bit per device batch.
Bluetooth/WLAN
Bluetooth depends on the resources being enabled by the WLAN driver.
