Title basically says it all: My phone with around 0.15 btc in the Mycelium wallet installed on it has a broken screen. I can get access to the SD card but not to the phone file system. I think i left USB debugging switched on so there should be a chance to access the filesystem and wallet, but I could use some starting hints. Thanks for any clues.  Smiley

edit: Downloading ADB tools now, let's see if I can find the wallet. Hints to where it should be found would be useful. Wink

I take it that you have not made a safe copy of your private key(s) to enable the BTC to be retrieved in the event of your phone being lost, stolen, or (as in this case) broken?

Indeed, I "forgot" the btc ("only 0.15btc lol") until the screen broke...

That looks very useful, big thanks already, will report back! Cheesy

Nope, too old (Xperia S).

edit: Can't access the file, possibly because the phone isn't rooted (I also get "no permission" errors when trying to list all files)? Or maybe I had Electrum not Mycelium installed (been a few months)... But since I can't list the content of the data dir, seems it's a permission problem.

edit2: The phone was rooted, su can do wonders. Turns out I had bitcoin spinner installed, will report back!  Cheesy

Thankfully the phone was rooted and USB Debugging was on or I probably wouldn't have had a chance. I did the following:

1. Download ADB Tools http://www.mediafire.com/?kovh575e97hu910
2. Install ADB driver if you haven't yet http://www.chip.de/downloads/Universal-ADB-Treiber_61437026.html
3. Open a cmd prompt and type adb shell
5. Type su, the $ should become a # if you have root access
6. cat /data/data/com.miracleas.bitcoin_spinner/shared_prefs/KeyManagerCache.xml
7. The private keys begin with <string name="bitcoin pri key 1">, copy those and import them into your favorite wallet (i used blockchain.info since Multibit was picky about the key format).
Huh
8. Profit!  Grin
