Lenovo Thinkpad Z13 Gen 1 JZ3A0 NM-E071 REV0.3 (or any rev) BIOS wanted

[rebellion]

Hello. If anyone has a working BIOS dump of the system, I'd appreciate it. My particular laptop seems to have a Macronix MX77U25650FZ4I42 (or MX25U25635F according to this post) which is not the Winbond W25R256JWEIQ in the retail model (at least according to the schematic I found here on the forum). But they seem to be similar, and I'll take anything because it's so hard to find anything about this device. Thank you.

I don't think it has a real serial number. I bought it second hand on yahoo flea market and the seller said it was a factory prototype model. When it was running before I bricked it, the cpu name showed AMD eng sample something, and there was a serial number in the lenovo vantage app, but putting it in lenovo's website showed no results. Unfortunately, I don't remember it now.

Rest of the info is in the title.
Model name : Lenovo Thinkpad Z13 Gen 1
Motherboard model: JZ3A0 NM-E071 REV0.3

I'm not sure what the type is. In the manuals it mentions 21D2 or 21D3 but I don't know how to check which one is mine.

I'm having trouble reading the chip now, but I've ordered WSON8 adapters and will post it when they arrive.
