Make sure your WBID has the latest save by playing a Faction Wars battle.
I have done this two ways:
Set the device in Airplane mode before launching the game. If you pick a kard you don't want, delete your save and reload the game. You'll have to go through the tutorial intro, but it might be worth the time to you.
Use Helium to backup your save. https://play.google.com/store/apps/details?id=com.koushikdutta.backup&hl=en. Set in Airplane mode before launching game. If you don't want the kard, reload your save from Helium, then launch the game again. Once you get the kard you want, lock it in by turning off Airplane mode, then playing Faction Wars to save it to your WBID.
Here is the link to download what vector uses.
But I don't support using it, I've heard people lose their accounts trying to use this fuckery
Use this auto clicker ( https://play.google.com/store/apps/details?id=com.truedevelopersstudio.automatictap.autoclicker&hl=en_US ) for test your might. You can easily destroy the test your might challenges.
I'm going to Google Play on my desktop and it tells me it's not available for my device, the Google Nexus 5. I live in the Midwest.
If you do not have the latest version of iOS, download iFun Box. Then you'll be able to copy your save file to your computer.
It also allows you to cheat the Kard Pack purchase system. Long story short, you backup your save and buy a pack. Shitty result? Overwrite your save. Rinse, repeat. Easy but tiresome way of getting gold kards from the 30k koin pack.
First of all go to settings,apps, mortal kombat, permissions, and switch storage permission on. Switch off phone wait a while and switch on.
1.If you use mobile data, switch to WCDMA only mode from phone settings.
Also if you use wifi try steps 2 and 3.
If all of that doesn't work, got no idea how to help. You've just gotta to send a ticket and hope for the best in that case.
Or something similar on iOS.
Last time I cleaned out my FOS packs, I set up my click sequence and just let it run. Took about two hours to clear ~180 packs, interrupted only to restart hourly quests.
I got this bug when I wasn't connected to online. I have a app on my phone though that lets me do the drop-down menu any time, and when I do that it kills the loading screen for some reason. Swipe Status Bar
Being online is much better. Having to use this workaround sucks.
