G+_John Lynch Posted February 2, 2015 Share Posted February 2, 2015 I have an issue. I have a Nexus 7 2013 addition, I unlocked the bootloader with towelroot and now I can't upgrade to Lollipop. Can anyone help me upgrade. Link to comment Share on other sites More sharing options...
G+_Scott Abramczyk Posted February 2, 2015 Share Posted February 2, 2015 What I would do is just use Wugfresh Nexus Toolkit. Go back to stock or use it to upgrade to Lollipop. Link to comment Share on other sites More sharing options...
G+_Mark Stronge Posted February 3, 2015 Share Posted February 3, 2015 Unlocking the bootloader does not effect OTAs, but installing a custom recovery will Link to comment Share on other sites More sharing options...

G+_L I Posted February 6, 2015 Share Posted February 6, 2015 I think you could download the factory image and install it without the wipe parameter. Link to comment Share on other sites More sharing options...
G+_Wayne Gomez Posted February 6, 2015 Share Posted February 6, 2015 I'll have to search for it Link to comment Share on other sites More sharing options...
G+_L I Posted February 6, 2015 Share Posted February 6, 2015 most of the android sites have instructions on how to install factory images http://www.androidauthority.com/how-to-manually-install-android-lollipop-nexus-device-windows-linux-563546/ MAKE SURE you edit the flash-all.bat file and remove the -w parameter from the last fastboot line. Also before you do this I would wipe the cache partition. Link to comment Share on other sites More sharing options...
