Looking for a dump of 25Q128 form USH board with NFC active from latitude 5420

Added NFC antenna and connected to USH board but nothing, I think is configured for card reader only and NFC RFID disabled.

Thanks.

Solved
Found all dumps from an 5500 LA-G902P, write USH dump, now both card readers appear in device manager

Would you mind sharing those dumps ?

Hi all,

I have a Dell Latitude 5420 SN: 4DRQ4M3 in store, costumer indicates that It doesn't turn on, but led light blink when power button is pressed.
We already traced that is some kind of indicator that it doesn't receive power.
USB-C only does 5V on 1 port, and other it doesn't turn on the Ampmeter.
UZ12, UI1 and UT3 present elevated temperature. Already replaced all of them.
Now the board indicates 5V on both ports, but it doesn't convert to 20V.
I would like to try another USB-C firmware if anyone could upload.

Already ordered the ISL9538C just in case.

I would apreciate if anyone could help.

post merged...next time look for a thread with the name and model, motherboard model of the laptop, and post there, if you can't find it, then make a new thread..

I did search and been spending hours looking for information, but all is related to BIOS, and not the usb-c Firmware, reason why I openned a new thread.
Thanks

On third message I uploaded dumps and explain why I didn't upload them

USH board are identical on many models and available device that can be connected to that board are:
- wired card reader
- wireless card reader
- fingerprint reader
But there is no way found to configure them to enable - disable one of the possible devices.
In may case was only wired card reader available, Added NFC antenna for wireless card but no effect.
After flashing dump found from that 5500 on USH board another one card reader device appear in device manager and wireless card reader works.
