Xenium Modchip Frag Porblem

hello I have a Xenium chip here.

The problem is as follows. The chip only starts with Frag.

The problem can not be the chip, because I still have 4 more Xenium here. These do not start either.

The board is 1.6. LPC Rebuild is alright. Was tested with an XT, this is running.

D0 was clamped by the board to the chip.

So what do you mean no OS on it? Or where is the problem?

greeting

What was the version of Xenium OS on the faulty Xenium chip before it stopped working?

I can not say if these 5 pieces have ever run before the expansion! Since I bought them myself without any info. I can not say which OS is on the chip.
It always comes only Frag

My guess is these units are clones and might have been updated to Xenium OS 2.x.x which is know to brick the clone units overtime. But this is pure speculation, we might never know what happened.

After careful physical inspection of all your units, can you spot potential physical damage to components on the modchips?

I checked all the units. 2 of them were installed via quick solder. 3 Not at all makes it the impression.
They seem okay from the optical state

After a lot of research I came to the conclusion that it really clone!
