I saw that there was OTA update available for the Droid 4 (January 2014) but it fails for me because apparently the VSuiteApp.apk that I have is not the one it's "updating"... the update fails with a checksum/hash error at VSuiteApp. I had previously converted the app to "user app" and it got auto-updated by Play Store. Does anyone have the correct version? I'd be really grateful if anyone could just find and send me their VSuiteApp.apk from the /system folder.... thanks. Those of you who are on JB 4.1.2 and have NOT updated to the January 2014 OTA should have the file I need.
