The bootrom here is located at 0x400000. It was initially dumped using exploits in java on other [[S-Gold 2]] phones. It allows unsigned code to be uploaded using [[Baseband Bootrom Protocol]]. On non debug variants of the chip, it requires [[Fakeblank]] to run that code

This exploit is in the Baseband Bootrom. There are hardware (testpoint) and software variations of this.

Description

If 0xA0000030 0xA000A5A0 0xA0015C58 0xA0017370 read as 0xFFFFFFFF on startup, the Baseband Bootrom Protocol can be used to download and run unsigned code. In the initial hardware unlock, an address line was pulled high to OR in hardware those addresses with +0x40000, making it instead read parts of the baseband firmware area, which can be erased.
