Kit Installation Tips + Tricks
•
Use plenty of flux when soldering the quick solder flex. It will make it much easier to get the
solder to flow onto the pin of the AGB-CPU as well as the pins of the quick solder flex cable.
•
When aligning the quick solder flex, ensure the pads of the flex are as close as possible to the
AGB-CPU pins as possible. There needs to be a solder bridge from the pin directly to the pad of
the quick solder flex otherwise there may not be a solid connection.
◦
Start soldering the pins of the flex to the AGB-CPU by soldering the outer most pads first.
◦
This means pin 119 on the left side of the AGB-CPU and pin 7 on the bottom of the AGB-
CPU and solder inwards towards the bottom left ground on the cable.
•
After the GBA is connected to the GBHD Advance mainboard, test the connections made to the
GBA by powering on the device and test using any game.

If you have a flash cartridge, it is recommended to use BtnTest by heroldev.

If a specific button seems to not work no matter how many times it has been soldered, that
specific pad (or pads) may have been damaged during installation. If this happens, use the test
points on the GBA motherboard to solder a wire to the test pads on the quick solder flex.
