I'm fairly positive that the problem is not a bad flash what so ever.
***The problem is with the firmware itself***When you first install v1.13 you can enter configuration changes with no problem.
- BUT...there is a time period (hours - perhaps days) after which the router refuses to allow any changes to be made.
- - To effect any changes, you need to do a hard reset of the unit (what you are referring to as a Crash Reset)
- - - But this time, the time period for making any changes is shorter. It was something like half a day for me. The next time after, it refused to even accept any changes.
Today after reading your success at returning to 1.12
I decided to give it a go.
My router was at the point where it refused to take any more changes what so ever. I couldn't even input a password for the Admin account. ** Definitely not good **
I was ready to trash the router what with how PO'd I was.
I've used tFtp before and I have used DD-WRT on other routers before, so I'm not new to using tFtp.
Well, needless to say, I couldn't gain access to the router using tFtp as the attempts failed. I completely tore the router apart, checking the whole thing out. Tried everything I could think of, then finally I was able to get it to respond!
It finally took a password for the Admin account.
After that, I was able to update the firmware to v1.12 successfully.

Not entirely sure, but the success was only after I had the unit apart and the black anodized metal plate removed from under the circuit board. I reassembled the unit without this metal plate and it seems to be working just fine.
All I know for sure is there is some sort of problem with the v1.13 firmware and it should be pulled.
