Hi, I've previously made a post here which helped me determine the likely cause of my booting issues to be the BCM4356. Since then I saw other people linking the orange screen and boot issues to the wifi chip as well. So my hopes were high to finally fix this.
Since then I've first reflowed, and then replaced the wifi chip twice, but I'm not getting anywhere.
To make sure the soldering went alright, I took some X-ray images of the chip and to me it looks good now. (The bottom one is a reference image from another board.)
Note that in my first (botched) attempt below you could clearly see some bridged solder balls. (In this state the switch wouldn't even power on.)
But I guess I don't know enough to clearly say if the chip is on correctly. Yes there are no bridges, but does the image indicate that all solder balls made proper contact with the pads? Or would that look slightly different? The current symptom is back to being stuck on the boot logo. As I've stated in my first post, the rest of symptoms are: everything works hardware wise in Linux, except WiFi (but Bluetooth does).
If you have any idea on how to proceed from here, I'd massively appreciate it.
