Soldering BK7231N CB3S Chip: Solutions for Lifted TXD1 Pad and Pin 16 Connection

I'm trying to flash a BK7231N CB3S chip. When I was soldering wires to the chip, I lifted the TXD1 pad off the CB3S board. I'm wondering if I can still make a connection to TXD1 somehow? Or have I ruined the board? See the image below which was taken before soldering. The pad I ruined is the one on the top right (pin 16). Also I am assuming that some of the pads on the device are just screen printing and don't require an electrical connection. The exceptions being power etc.

Hello, what is the current state of the pad and how precise your soldering skills are?
The CB3S pad is damaged, do i understand correctly?
Maybe there is still some point to solder to, if you clear the board.

You could also remove the metal shielding and try to find out where the missing signal goes... and make a jumper with very thin wire.

My soldering skills are pretty good (15 years of soldering in a production environment), but my current soldering iron is not good, hence the lifted pad. I've had a closer look and it seems that the whole pad (on top and side) is gone. After looking at the spec sheet, it seems that there is a pad underneath the chip. Perhaps I can slip a thin wire underneath. Yes, as you suggested I could try removing the cover.

Even if the track goes on the bottom side of the board, the BK7231N is at the top side of the board, so there must be a via somewhere. Maybe it would be possible to remove the shield, find that via, remove the soldermask and solder to it...

btw, what kind of device do you have? Do we already have it listed https://openbekeniot.github.io/webapp/devicesList.html ?

Yes, there's a good chance of picking up a via somewhere.
My device is a Brilliant Smart WiFi Powerboard 20691/05 sold in Australia through OfficeWorks.
There is an ESPHome page for it https://www.esphome-devices.com/devices/Brilliant-Smart-Powerboard.
I created a .bin file through ESPHome, hoping that I could do a Tuya convert, then migrate to ESPHome.
I'm assuming I can transpose the GPIO mapping from the ESPHome page to the device once I've flashed it.
If I get it all working, I'll make a submission to the site.

Hey @Mulberry6642 , have you considering the OTA hack approach for flashing your device? You have a broken UART pin but it could be flashed maybe without it.
