I remember that discusion as I was in on it.
Data can be writen to the wrong areas like radio.
Our rom flashing is not perfect I think.
I used to flash eeproms for hacking back in the day and sometimes it took a few tries.
Just like defraging a windows pc helps fix problems.Files can get misplaced and a data string can stray.
Most of us that have been flashing a while understand a clean stock flash can fix and replace broken or misplaced code or data.
Sometimes making cds or dvds can also take a few tries. Same thing happens. A fluke in data writing.
In any case a stock flash can and does help with some problems.
