You spent hours on your castle, and then a new version arrives. Now you worry that an update will wipe your work. Good news: you can update Lovely Craft and keep your progress. You only need to follow two rules from this site: do not uninstall first, and back up before you update.
Why Players Lose Worlds During Updates
Most lost progress comes from one mistake: uninstalling the game first. When you remove an Android app, its saved data often goes with it. The second cause is a broken install. A half-finished download can damage the data. A backup protects you from both problems.
Rule 1: Never Uninstall Before You Update
This is the most important rule. The 0.2.999 Update guide says you download the new APK and install it over your current version. You do not need to uninstall first. Your saves, emeralds, and unlocks stay in place. So the safe path is simple: download the new file and install it over the old one. Do not remove the old game first.
Rule 2: Back Up Your Worlds First
Even a safe update can go wrong. A backup takes a few minutes and saves hours of work. This site’s Save/Backup guide explains the method: open the game and look for a Maps, Worlds, or Save menu. Select the map you want to keep. Check the menu for an Export, Share, or similar option. If one is found, export the map and note where the game saves the file. Then open your phone’s file manager, find the exported file, and copy it to another safe place, such as a separate folder or cloud storage. Keep two copies in different places, and check that the copy exists and its size is not empty. A map export may save only a map or construct, while a full save backup option may also contain other progress, so check the in-game menus for Export, Share, Import, or Backup options before you proceed. Menu names may vary per version.
Step-by-Step: How to Update Lovely Craft
Check your current version. Open your phone’s Settings, go to Apps, find Lovely Craft, and look for the version number. You can also check the version number in the game’s settings, as the 0.2.999 Update guide explains. Compare it with the latest version. Visit this site’s download page and read the version number. The latest version on this site is 0.2.999, about 139 MB, for Android 5.0 and up. Back up your worlds. Follow Rule 2 above. Download the new APK file. Wait for the download to finish and check that the size is about 139 MB. Open the APK file and tap Install. It goes over the old one. Allow unknown apps for your browser if Android asks. Open the game and check your worlds. Load each one and make sure your builds are still there. If a step shows an error, stop and read the fixes below before you try again.
How to Go Back to an Older Version
A new build can sometimes change a feature you liked. If you want to go back, you need the older file. This site’s Old Versions guide explains the safe path: back up first, because worlds saved in a newer build may not open in an older one. Then uninstall the new version — this step is needed here, because Android blocks installing an older version over a newer one. Install the older APK, then restore your backup and test whether your worlds open. Be careful: a save created in 0.2.999 might reference mobs, items, or systems that do not exist in an older build, so treat the old version as a test environment unless your backup works cleanly.
How to Move a Backup to a New Phone
Copy the exported file to a safe place for transfer, using a computer, a memory card, or cloud storage. Install the game on the new phone, move the backup file into a folder that is accessible, then use the Import option in the game’s map or save menu to import it. Use a version that is compatible with the backup file. A newer or older version may not be able to import a map in the same way.
Fix Common Update Errors
“App not installed.” This often means a damaged file or a conflict with an old copy. Download the file again and check that it is the complete 139 MB APK. If the error stays, you may have an unofficial copy installed. In that case, back up your data first, then remove it and install the file from this site’s download page.
“Parse error.” The file did not download fully. Delete it and download it again.
The game closes after the update. Restart your phone. If it still fails, clear the game’s cache in Settings, Apps, Lovely Craft, Storage. Do not choose “Clear data,” because that removes your saved progress. The Best Settings guide notes that clearing the cache usually does not delete progress, but it is safer to back up first.
Worlds are missing. Do not panic. Check that you opened the right map or slot. If they are gone, restore your backup using the Import option described above.
Tips to Keep Your Worlds Safe in the Long Run
Keep two copies of every backup, in different places. A copy that is only on the same phone is at risk if the phone is lost or damaged. Name your backups clearly, with the date and version, so you know which one to restore. Keep free space. An update needs room to unpack, so keep at least 500 MB free, as the System Requirements guide‘s minimum storage range suggests. Update on Wi-Fi. A weak connection risks a broken download. Do not use mod files. Unofficial files can damage your saves.

Updating Lovely Craft is safe when you follow the rules. Back up your worlds using the export method, never uninstall first, and install the new APK over the old one. Check your worlds after the update, and keep your backup until you have verified that everything works.
