Macbook A2289 Shutting Off Immediately

No Corrosion.
Disconnect the trackpad and it stays on but it turns on on a weird screen. The screen shows - to connect a wireless apple mouse and keyboard (graphic images).

Tried another trackpad and another cable too.

What can be the issue?

With TP/KP connected. Won't go into Safe Mode.
Tried Command + R just to check. Stuck at boot loop apple logo..

Put it into DFU. It stays - checked for about 90 seconds

DFU Revive Gives this error.

The operation couldn’t be completed. (AMRestoreErrorDomain error -1 - Failed to handle message type StatusMsg (Generic error)) [AMRestoreErrorDomain – 0xFFFFFFFFFFFFFFFF (-1) [sys = 0x3F, sub = 0xFFF, code = 0x3FFF (16383)]]

Tried with a different trackpad and cable as well. But its for A2338 - I don't think it matches.

Tried known good trackpad board/cable from same A2289 model?

Still stuck on network connection?
Tried external keyboard/trackpad?

I was referring to this; not to DFU behavior...

Hi,
tried restoring with a known good trackpad as well. Same -1 error.
I think board not detecting trackpad.

Shorted Lines

3v3_g3s_tpad
3V3_TPAD shorted too.

Injected 1V. Replaced the bad cap.

Still needed to replace the Trackpad as the old one doesn't work.

Issue Resolved . Installing NewOS
