Hello,

I can't figure what what Bootrom an iPhone 3Gs is running.

When in DFU mode, here's what system profiler says : iBoot-359.3

The model number starts with MC

The serial number's first 5 characters : 5K111

f0recast answers NO for Untethered?

This iPhone was Jailbroken in order to be unlocked so it has iPad BB 06.15.00

I'm trying to downgrade it to BB 05.13.04

Thanks a lot

That's a new bootrom because it was made in 2011. The old bootrom was only made for a few months in 2009.

I agree, both the serial number and the MC in the model number indicate that it's a new bootrom but i read that iBoot-359.3 means it an old bootrom.

that's why i'm confused

At the iPhone hacks section.
You can use iDetector to verify if its new or old bootrom but like said above its the new one.
◦iPhone 3GS New BootRom [iBoot-359.3.2]
◦iPhone 3GS Old BootRom [iBoot-359.3]

The MB/MC model does not mean anything for a 3Gs. I have an old bootrom MC model and have seen new bootrom MB models.

According to iDetector, the iPhone contains Old Bootrom ..

So on one hand :
iDetector & System profiler [iBoot-359.3] = Old Bootrom

On the other :
Model number and Serial number = New Bootrom

Is this crazy or what ?

It is possible that the iPhone is a refurbished one that was given a new serial number.
