That's good. Post which big coils get voltage? BTW, write directly into bottom reply box, instead of clicking Reply button.

With external monitor (internal LCD disconnected), are you able to enter macOS?

Camera can't cause image artifacts. Check if 3V3_SW_LCD and LPDP_INT_HPD have stable voltage. Are you sure nobody connected an Intel based screen before (for testing purpose)?

First of all, welcome to the forum! What is exact PPBUS_G3H voltage? Be aware, this board doesn't start with 45/61W charger, if battery is empty. Use 87W charger, to avoid any surprise.

Did you test with lid sensor disconnected? Bad lid signal can disable trackpad; and keyboard will not work without trackpad.

Compare readings with good board. Still goes off if you try to enter Options menu?

Any programmer works, even the cheapest CH341. You just need to get a proper adapter board to solder such chip.

Compare diode mode readings in the backlight area with good board. If not available, use refference table: https://openboarddata.org/?a=showboardsolutions&bpath=laptops/apple/820-02100

No schematic available. U7000 means what, which schematic refference for it?

Try restore more times; always starting from DFU, not Recovery.

I tried to explain you that sometime revive doesn't fix problems. As in my case, restore was completed without error. If you already tried restore and still failed, the problem may be on the T2, or SSD side. Few days ago also told you that restore may fail several times and one day completes...

I had one A1932 on the desk yesterday. It failed revive with error 4041. However, restore was successfully completed from first atempt. BTW, needed to switch from Recovery to DFU with external switch, in my case.

First of all, welcome to the forum! You can replace only U5500, but must get it from donor board, same model and position. Just in case, reflash U5560 first; if you can get good working dump.

If you start from Recovery, instead of DFU logo, that may cause the error. So try again once AC2 shows DFU logo...

So, I explained you how to force it in pure DFU, not Recovery. One week ago I had problems with an A1989 and took me various minutes to switch from Recovery to DFU. It completed DFU restore after several tries (more than 10 times).

"i see it in Apple Configurator not in dfu But in Recovery"

I told you how I proceed in such case. The problem with your model is that you don't have dedicated pads to solder a switch for SOC_FORCE_DFU signal. You need to solder tiny wires to corresponding points, on back of the MLB...

You've said it appears in Recovery, not DFU. Or do you mean that it starts on Internet Recovery mode in fact?

Pressing power button 10s should turn it off. Not sure if you can access pure DFU mode with keyboard only. I do it using external switch method usually.
