My primary ROM was cm11/AOSP as well as the 2nd and 3rd. I removed the 2nd and 3rd ROM and rebooted to primary ROM. Booted back to recovery and just flashed the uninstall zip and rebooted and that is when the fun happened. Lol.
Same here, I'm sure I didn't mess up anything as I've been playing with Android phones for a long time now and have enough knowledge to know what I'm doing.
Couldn't get past the OnePlus kernel logo after running the uninstaller.
Also, afterwards I had issues pushing files using adb when booting in fastboot mode.
Luckily fastboot did work, so I was able to restore an original image.
I guess the uninstaller still needs some work.
It's too bad I lost all data on my phone because of this...
The thing is it's a shame you can't back up to an external SD card with this phone and I'm really not going to hook it up to a PC all the time in order to save my data. (Or maybe I should from now on )
