Unbrick Your Hummingbird-Powered Device by Creating Your Own Bootloader

How would you like to create your own bootloader? Sounds a bit daunting, no? Aside from the inherent “cool factor,” having this ability could get your device out of some tough spots that would otherwise require the use of JTAG.

Thanks to the work of a team lead by XDA Recognized Developer Rebellos, this is now possible for Samsung S5PC110-based (read: Hummingbird) devices. Since there are quite a few Hummingbird-powered devices roaming about XDA, this can prove quite useful for when ODIN is not enough or if your JTAG pins are nonfunctional.

In the words of the developer:

What is it?
Info how to bypass secure booting mechanism built in S5PC110 CPU’s iROM on lowest level and create code loadable even with totally damaged bootloader, without use of JTAG.

Okay, how useful is it?
I’ve got no clue, it all depends on you. Our main target, which is almost done, is ability to revive any hard-bricked hardware built on S5PC110 without use of JTAG (for eg. when JTAG pads had been damaged)

In order to get started, venture forth to the original thread.

[Thanks AdamOutler for the tip!]
