I really like Tetra Lockscreen and have it installed on my Lumia 822. I have an SD card but I don't know where it is installed? I don't like the idea that I wouldn't be able to download it, if something happened to my phone. Let me know if I can help.
If your version is the last they released(has weather widget/bing images/etc) then your help would be greatly appreciated .
Theres only a couple things I would need you to do. If not already move tetra lockscreen to your sd card usng storage sense. Then after that pop you card into your pc.
Now if you are able to zip these 3 folders (might have to rename one as most likely named similar)
1.Once you pop in sd card into you pc, Open it and should see a WPsystem folder (might have to unhide files/system files in windows)
2. Go to Wpsystem -> AppRepository -> copy tetra lockscreen folder to pc (should be named as such or Microsoft tetra lockscreen) rename it tetra1
3. Next WPsystem -> Appdata -> Local -> packages -> Copy tetra lockscreen folder to same folder as previous and dont rename
4.Wpsystem -> Apps -> WindowsApps -> Copy tetra lockscreen folder to same folder as the prior two and dont rename
5. You should now have a single folder with 3 different folders copied from you sd card
6. Create a zip/rar/7z/etc of the folder that contains the 3 tetra lockscreen folders and post here
7.Move tetra lockscreen back to internal memory if thats where it was installed.
If any of the folders is missing as long as the one from the Apps folder is there i should be fine, just asking to copy all so dont have to bug you more than once.
Thank you in advance if have any issues or trouble finding the folders just ask and i shall help guide.
