Default LK (Little kernel) mode

Something I found, may help with troubleshooting non booting kernels

I think it just bypasses first boot splash screen

Volume up + Volume down + camera + power


Little kernel is our secondary boot loader which initializes the Linux Kernel zImage and Ramdisk

https://www.codeaurora.org/2010/03/02/little-kernel-based-android-bootloader/

It is not GPL so Samsung does not have to provide source code.

HW Revision 9
Booting Linux @ 13008000
ramdisk@ 14000000

cmdline: mem=336M console=ttyMSM2,115200 hw=9

I believe it is one of the UART interfaces of the MSM chipset, but how do we connect to it?

One of these days, I'll do a dis-assembly of my phone, or I'll buy a busted one to tear down.
Maybe I'll find a JTAG header or something fun

My biggest fear is a piece of fuzz or dust between the display and the touchscreen that would piss me off every time I look at my phone
Oh, that and snapping a spring-tab when taking the phone apart
