Use following tool. Mycelium apparently has some issues with restoring old backups.
https://github.com/mycelium-com/wallet-android/blob/master/backuputil/src/main/java/com/mrd/bitlib/BackupUtil.javaThis allows you to produce a WIF key, which should be usable in new mycelium.
Let me know over PM, if you'll need help to run it.
EDIT: Attached a guide
Go to backuputil/bin directory and execute
backuputil.bat encryptedKey PASSWORD
like
backuputil.bat xEncGXICZE1_eVYfGWDioNu_8hA6RZzep4XqwPGRtcKb01MDg3s1XFntJYI9Dw QDTDXOYFBXBKKMKR
This will show you "Private key (Wallet Import Format)".
Send it to your mobile phone (using chat or whatever)
Copy it into clipboard
Open Mycelium > Accounts > Key+ icon > Advanced > Import (this should allow you import from clipboard)
1) Pre-built version (I built it straight from mycelium repo like 30 minutes ago)
Here you can download ready-to-use backuputil.
2) However if you don't trust these binaries (which I totally respect), here is a guide how to compile your own.
- Download and install Android Studio
- In the 2nd step of welcome wizard choose "Custom"
- Check "NDK" in the next step and let the installation finish
- Dowload zipped backuputil source code (green button on the top)
- Unzip it and using command line go to backuputil from the zip file above
- Type "gradle build" into command line
- Go to newly created folder build/distributions
- Unzip backuputil.zip
