Can anyone link me to or sell me a U4801 for a 3662(2014) 15" MB?

[Hellfiya]

I have a 3662 with a bad U4801 and need to find a replacement. After I tried one from a 2012 3115 and didn't work, I was informed by duke that the IC has firmware on it.
I found a link to some on Aliexpress: https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20180501130529&SearchText=CY8C24794
but I wouldn't know how to program them if it has firmware. It looks like I need a CY8C24794 MLF-1 with Sym version 2, which in schematic shows its the same as the 3115, 2012.

Does anyone have a working 3662 or 3787 with a dead cpu or something and would be willing to sell me the u4801 off it? I can pay through paypal or venmo or something.

What's wrong with buying donor boards?

Anyway, I have a few if you're in the UK.
I imagine that the 820-3332 U5701 has the same firmware. I could be wrong but I would have a bet on it.

3332, 3787, are the same for sure. Get some donor boards, you will always need them.
