Register as many trainers to the PokeNav as possible.
Open the PokeNav Match Call feature and select all the trainers you registered in the tool below.
Proceed to the next step.

Optional, but highly recommended: Put a Pokemon with Lightning Rod and Flame Body in your party.
- Electrike with Lightning Rod is on Route 110, just South of Mauville.
- Slugma with Flame Body is in Fiery Path, just North of Mauville.
Buy at least 3 normal repels from Verdanturf.
Go to the Daycare and withdraw any Pokemon currently there.
Stand in front of the top right edge of the white path on Route 118.
Use the first repel.

Walk left until you're in front of the Daycare, then walk up until you're in front of the Daycare lady.
Deposit your parent Pokemon into the Daycare.
Exit the Daycare.
Talk to the Daycare Man to get the egg compatibility and write it down for later.

Walk to Verdanturf and run around.
Use the second repel.
Run around Verdanturf and use the third repel.
Stand next to the tree closest to the PokeCenter (screenshot below).
Walk back and forth on the two tiles in front of the PokeCenter until the repel wears off.
Save the game and proceed to the next step.

If you are using a Ditto with a genderless or male parent, enter the information for the Ditto as the "Female".

Make sure the Lightning Rod Pokemon is in the front of your party and save.
Start the timer below.
When first timer goes off, soft reset your game and load your save as fast as possible.
Walk back and forth on the two tiles in front of the PokeCenter for 9 steps. DO NOT move anywhere else.
Open and close the Pokedex this many times: ???
Take 1 step on the same two tiles when the timer goes off.
If you received a PokeNav call that matches your expected call and the Daycare man has an egg, save the game. If not, scroll down to the "Calibrate" section.

Pick up your egg from the daycare man and hatch it. If it's shiny, proceed to the next step.
If the egg wasn't shiny, fill in the tool below with the match call and egg nature.
Press "Find advances matching eggs" to view a list of possible eggs.
Press "Calibrate" on the egg with the offset closest to 0 to adjust the timer.
Restart the PID RNG process.

Tip

No results? You may be outside the search window or miscounted Pokedex opens.

Advance range: expands how far from your target the tool searches.
Pokedex range: checks nearby counts if you miscounted openings.
Still failing? Every 128 steps, the game checks your party's friendship, which can throw off the RNG. To offset it, pick up or reject your current egg, save, and restart the RNG from the beginning.

Stand next to the Daycare man and save.
Start the timer below.
When the first timer goes off, soft reset your game, load your save, and talk to the Daycare man as fast as possible.
Continue the dialogue until you see the text "Take good care of it".
When the second timer goes off, press A to receive the egg.
Hatch the egg.

Enter the stats in the tool below and press "Find advances matching hatched egg".
If the result with offset 0 matches your target stats and method, congratulations! You got your egg!
If the result with offset 0 doesn't match your target method, try again without calibrating.
If there is not a result with offset 0, click "Calibrate" on the result with the offset closest to 0 to adjust the timer.
Restart the IV RNG process.
