Resistor R2219 is most likely 10 ohms also check diode D250 it could be shorted.... -
Technical Analysis: Resistor R2219 (Ubiquiti US-8-150W)
In the Ubiquiti UniFi US-8-150W switch, the resistor identified as R2219 is located in the power section, specifically near the FDP2572 MOSFETs (usually within the PoE delivery stage or the internal power supply unit).- Standard Value: If this resistor is connected directly to Pin 1 (Gate) of the FDP2572, its typical value is 10Ω (10 Ohms) or 47Ω (47 Ohms). These are typically SMD components (often in 0805 or 0603 packages).
- Function: It acts as a Gate Resistor. Its purpose is to limit the switching current to the Gate

Hi everyone,
I wanted to give you a quick update on my situation. Thanks to the advice received here and the use of an external programmer, I managed to solve the issue!
Specifically, I successfully flashed the .bin file you previously sent me, and the laptop is now booting perfectly—it’s incredibly fast.
While I was waiting for a further update, this previous file combined with the external programmer did the trick, so the machine is now fully functional.
A special thanks goes to the Moderator and the whole community for the invaluable support....Leave a comment:

I have successfully extracted the original dump from the chip using a programmer, and the read has been verified. Although the file is corrupted and I cannot find the DMI strings in plain text with UEFITool, I am sure this is the original data from the motherboard.
Could you please help me rebuild/clean a working BIOS file using my original...Leave a comment:
