🔧 Repair

Fixing radios: connectors, buttons, displays, the dreaded brick — sorted by model.

Most radio failures are typical and can be fixed at home: a worn-out SMA antenna socket, an oxidized volume encoder, broken battery contacts, sticky buttons. And a brick after a botched firmware flash most often comes back to life through the emergency bootloader.

Here you'll find model-by-model repairs (TYT, AnyTone, Baofeng), replacing connectors without overheating the board, and restoring firmware. Before any firmware flash, always back up your codeplug.

Replacing the antenna connector on a radio: soldering SMA without surprises

The connector is a radio's weak spot: we take it apart, desolder the worn-out SMA socket and fit a new one without overheating the board or mixing up male/female.

Frequently asked questions

The radio won't turn on after a firmware flash — what do I do?
Enter the emergency bootloader/DFU mode for your model and flash the firmware again. In most cases it recovers; if it doesn't — take it to a service center.
Why is the volume crackling and the channels jumping?
The volume control encoder has oxidized. It can be cleaned with a dedicated contact cleaner spray, and replaced if heavily worn.
What breaks most often in radios?
The SMA antenna socket (especially when antennas are swapped frequently), the volume encoder, the buttons and the battery contacts.
