Extra ⭐ (I will add more stuff here)
Installing apps with Veteris
You want to install apps right? Well, it's kinda impossible now because of the App Store changes
Open cydia and add this repo http://yzu.moe/dev/ and install veteris from the utility sub-folder
To make it work You will need AppSyncUnified from https://cydia.akemi.ai
Fixing YouTube
"Aww man, i wish i could watch YouTube on my iPhone 5 like old times"
You now can with TubeRepair by bag.xml, she made this majestic tweak!
Add bag.xml's repo: http://cydia.bag-xml.com/
After you added the repo and installed the tweak type a link for an active instance in the settings (in the settings app scroll down until you find TubeRepair, now click on it and paste/write a URL for an active instance), my personal favorite is https://tuberepair.uptimetrackers.com/
I reccomend You to use Youtube 1.2.1 (you can install it from Veteris)
Fixing system apps
You will need the repo that i mentioned in the Installing apps with Veteris step
After you added that repo add to the queue StocksX and WeatherX and, from another repo (cydia.skyglow.es) MapsX after that install all of them and you should be good to go!
