Hi All
I found this thread as Ive just updated my phone to v20 firmware and I forgot to uninstall a few apps off the SD card before doing the upgrade. Because of this, the apps still appeared but couldnt be uninstalled, as above. In addition, two out of the four apps (Google Maps and Yell.com) I didnt have install files for and those available on the net were now newer versions meaning I had no easy uninstall method
Eventually I got these apps removed without formatting the SD card so I thought Id share my findings....
Basically I had a good hunt around the card, viewing it in a card reader with hidden files showing (or probably using something like X-Plore on the phone, again with hidden / system files shown), and found these folders in particular that related to the "orphaned" apps
System\Install\Registry - in here was a .reg file for each of the two apps I was trying to uninstall
private\10202dce - in here were some unknown format files which when edited with notepad, had comments in them which suggested they were related to the apps
Private\10003a3f\import\apps\NonNative\Resource - there we 6 files in here, two called Iconxxxxxxx.mdm, and 4 other files, again when edited it was obvious these were related
I started off deleting the reg files and the ones in private\10202dce, this effectively disabled the apps completely so they didnt try to reinstall when the memory card was put in, and if selecting to remove, would not do anything at all (not even "Removing Failed"😉. Basically i was just left with the icons showing
I then found and deleted the 6 files in nonnative\resource and the icons have now disappeared, so hopefully thats the last I'll see of them.
I can't promise every app will be the same, but hopefully it will point people in the right direction. A note to myself in future though, I'll either install all apps to the phone itself so they automatically get wiped when upgrading, otherwise I'll have to remember to uninstall any apps installed on the SD card first!
