iPhone No WiFi / Bluetooth? Fixing Damaged Sandwich Pads (Full Guide)
If you’re dealing with an iPhone that has no WiFi, no Bluetooth, or greyed-out connectivity, there’s a good chance the issue isn’t software — it’s damaged pads between the sandwich layers of the logic board.
In this video, I break down exactly how to repair interlayer pad damage inside the iPhone motherboard — one of the most overlooked causes of connectivity failure.
This is an advanced-level board repair focused specifically on:
Diagnosing pad damage between layers
Identifying failed WiFi/Bluetooth communication lines
Proper pad reconstruction techniques
Restoring full functionality without replacing the board
If you’ve already ruled out common issues like baseband, WiFi IC, or software faults, this is the next level repair you need to understand.
⚠️ This repair requires micro-soldering experience, proper tools, and patience — not recommended for beginners.
Whether you're running a repair shop or leveling up your board repair skills, this technique can save boards that would otherwise be written off.
