Sword Art Online: Memory Defrag - Optimal Rerolling For 4 Star Characters
This demonstrates how you can redo the opening 2 gacha rolls of the game within the tutorial in order to get the character you want (preferably a 4-star version as those are strongest).
I'm showing how it's possible (with "root access" to the game files) to negate the need to uninstall/reinstall the game AND download about 500MB of data every attempt, as would be necessary on an "unjailbroken" iOS device).
This is best done either on an Android device or on a computer using an Android emulator as for best speed you need to delete a couple of folders within the game that have to do with your created account.
Those folders are:
/data/data/com.bandainamcoent.saomd/files/memories/json/app_data
/data/data/com.bandainamcoent.saomd/shared_prefs
(The "com.bandainamcoent.saomd" folder name may vary slightly depending on region. Mine ends slightly differently.)
Here is a text guide explaining the process: https://saomdtranslations.wordpress.com/how-to-reroll/
Argo will usually look more cute/sparkly when you're rolling a 4 star character. She'll do something like this:

Alternatively she may do that more squinty-eyed smile without sparkling. That's an indicator too.
From my experience, this guarantees a 4*. It seemed to me I got one on occasion with a more normal pose but if I did, it's rare.
You may decide you want to save yourself a few seconds and reroll the moment you do NOT see the above Argo signs during your second roll attempt! These signs are shown in action at 10:55 in the video. If you're more cautious though, you can just press "skip" to quickly see what you've got.
DISCLAIMER: I'm aware of faster methods that allow you to SKIP the tutorial. I've covered this in a subsequent video:

However, this is only good for doing the FREE reroll. It's good for getting most characters but personally I never saw 4 star Strea or Silica on it. I don't think I saw Yuuki on it either, my memory is hazy as to how I acquired Yuuki. So if you're after either of those characters you should probably stick to the method in THIS video. Anyone is free to confirm they've found these three characters on the free gacha!
I'm doing it on a computer precisely because my phone is iOS. Saves me a fortune in battery power, I just transfer the winning account to my phone afterwards. The program is "Nox App Player". You may download that for free here:
Windows: https://nox-app-player.en.softonic.com/
Mac: https://nox-app-player.en.softonic.com/mac
Alternatively, just Google "Android File Manager" and take your pick! You will need to install the game and file manager via the Google Play app.
CAUTION: Please bear in mind (if you're not familiar with root files) that you must do exactly as shown in the video and delete NOTHING else. You can mess up your device/game if you delete the wrong stuff. If you're not confident about this, do not attempt it!
