KOKOBOI:

Where did you get this Dallas and do you still have your OLD dallas?  If your Dallas is FAKE...could this happen?  Kaigan is right, a dead Dallas battery on a working Dallas IC will work fine with power...use that as a troubleshooting guide.  I've personally NEVER seen a "dead" Dallas Chip (not working), only a dead battery...your L1 keeps trying to make alterations to NVRAM, I assume UNsuccessfully.  Perhaps this could be the reason?

ALSO, there was an experiment not long ago from jwhat that proved a Tezro will happily accept a BLANK L1 Dallas...but will NOT ACCEPT, NOR ERASE, a USED DALLAS! So there are two options there. Either use a dallas that was drilled with a battery and remove the battery to blank it, two use a programmer to "erase" the old NVRAM data through programming commands. If you got a USED dallas instead of the blank one, the Tezro would reject it with serial errors, though I didn't see that in your output you posted.

I've purchased it from aliexpress, so it's probably not blank. My programmers doesn't support this model... so I have no way to clear it.

I know you said things were still a problem with your OLD L1 Dallas, but try the old one with NEW snaphat on IO9 anyway and try reset procedure again. See if there is a difference.

The snaphat has been replaced with a brand new chip at the beginning, no difference.
