At first I though it crashed too, but when I was gonna restart it did it by itself.

Mine really crashes, as in after a bit the speakers pop, LEDs light up, and system turns off. Possibly just a difference between 2000 and 3000 :P

What would be usefull is :
- To know exactly what kind of operation in flash0 should not be done (to avoid a brick)
- To know exactly what the Fake Ident in 6.20 TN-B does.

Then we would be able to test things...

could it not work because you are trying to downgrade while you are in dual boot :?

Messing with any firmware files, just about any file could cause a brick if modified/replaced.
- To know exactly what the Fake Ident in 6.20 TN-B does.
It uses a version.txt to reproduce an index _0xg.dat to use in RAM instead of the original one in flash0.

That has nothing to do with it.

read this, quote from coldbird:
No you can’t downgrade. In fact this isn’t even a problem with 6.35 PRO, but with Sony.

Sony removed Updater Kernel Module Support for old Kernel Updaters in 6.35, so… once you go 6.35 – you don’t go back.

That’s it basically.
