This is practically useless, but FYI:
The fastboot built into abl (at least for the Poke3) has the following additional OEM (i.e. additional) commands:
Code:
oem enable-charger-screen
oem disable-charger-screen
oem off-mode-charge
oem select-display-panel
oem device-info
oem cpu
oem rsn
oem wsn // DANGER
Examples of things that are harmless:
Code:
C:\>fastboot oem device-info
(bootloader) Verity mode: false
(bootloader) Device unlocked: true
(bootloader) Device critical unlocked: true
(bootloader) Charger screen enabled: true
C:\>fastboot oem cpu
(bootloader) CpuID=12345678
C:\>fastboot oem rsn
(bootloader) EMMC Read SerialNo failed
Your CPU ID is the permanent one burned into the chip, the same as you get when using EDL, but unrelated to the the ID that "fastboot devices" or "adb devices" gives you.
I presume that the wsn is used to write an override value in the flash. I'm not sure for whom this would be useful.
