so what r u saying? the added chip carries 3.55 cfw with the hash checks removed. And the original chip and syscon are on the latest firmware.
Patch LV1 in the 3.55 firmware on the added flash to not do the checks.
Firmware hash checks are located on SYSCON EEPROM, aparently these checks are run within Indi info manager on LV1. These compare the hashes stored in syscon with the files stored on flash. If the checks fail, the console does not boot. We could get around this by using dual-banking on SYSCON or by patching the checks out.
Syscon and the original flash are allowed carry the latest firmware
