what are you planning to do with them?

I am suspicious of anyone doing this, and suspect they try to scalp (sell) them with inflated prices online.

My excuses in advance if this is not what you want to do.

perhaps you could state WHY you want to buy a defective PI4 ?

If it is to repair another PI4 with a defective PMIC chip then its fine, but you would be wise to ask for a defective PI4 that does not have a defective PMIC chip as well.

P.S. this forum software does NOT support personal messaging!

So I thought this over and decided to unlock this thread. My understanding NOW is that you want an old non working PI4B to use its PMIC chip to repair your currently non working PI4B, and that is a legitimate, but desperate, reason to want to buy one. I hope that the PI4±B you are buying doesn't also have a defective PMIC chip! it a common defect mode.

a good target, is one where the hdmi diagnostics come up, but the SD socket has been ripped off

ive seen 2 or 3 of that on the forums, so the PMIC/soc are clearly working
