Talk:Baseband Bootloader

5.8

The fact that dev team could change the baseband firmware implies there is an exploit, doesn't it?

I guess that the 5.8 exploit doesn't allow unlock because of sigcheck. Is the bootloaders 5.8 or 5.9 in the ramdisks? And is it possible to downgrade from 5.9 to 5.8 (maybe running some code in the baseband thru the at+stkprof to ask to erase the bootloader). Last thing, does 5.8 allow downgrading from any baseband? dranfi 4/10/09

There's an exploit somewhere, but it's not publicly known where.

They claimed to use the buffer overflows.

I found an exploit in 5.8, wait for details, I'll write it up. If it does what I think it does, it'll allow downgrades.
