Title: [Discussion] What do you think the 'Keyguard' and 'SystemUI Update Helper' updates are for?
Post by: coppyhop on March 05, 2017, 07:47:38 pm
With the recent release of 2 Updates on the stock ROM for 'Keyguard' and a new thing called 'SystemUI Update Helper', it got me thinking, maybe we could get an OS update (not from 'Keyguard' but from the 'Update Helper').

These two are very vital to system operation, I will break them down for you.

Keygaurd:
This is the lockscreen, it is the interface and also how it operates. On the LG G3 ROM if you update this, the material design lockscreen will remove itself and then turn into the default Optimus UI.

SystemUI Update Helper:
I am actually not 100 percent sure what this does, but the System UI is the status bar and a few small other things. I would venture to guess this updates the status bar.

My guess to as why these updates have been released is to remove the customization made to the LG G3 ROM and the UltaLoli ROM to restore them to default look. Updating theese will probably break a few things as there are a couple things in the status bar and lockscreen apks that require certain resources. if these are missing, the device will pretty much be bricked. A broken keygaurd is just like a broken phone, I busted system UI almost as bad.

My recommendation is to hold off on updating these until I can get a closer in depth analysis of these, but I am for sure that these can be patched on both ROMs.

I trashed my Galaxy Core Prime a few weeks ago (1st & last Samsung I'll ever own), now I'm back on my Ultimate 2.  I wiped the data, restarted, and no sooner than I finish the initial setup process, 2 LG updates immediately start downloading, so I didn't have choice.  After the updates finished, I rebooted, and the lockscreen had a button at the bottom for "emergency call", and a message under the clock widget that read "No sim card".  Furthermore, the lockscreen shortcuts were gone, so I uninstalled the keyguard update.

After another reboot, the lockscreen was completely gone!  I had issues in the past like this, if I disabled the LG Home launcher, or removed the ChromeWithBrowser.apk, and a few other ROM changes.  And once the lockscreen was gone, I couldn't figure out how to get it back, short of restoring a backup image, or worst case, resetting the phone again.

So when the LG updates started downloading after another reset, I cancelled the keyguard update, but I couldn't stop the SystemUI Update Helper in time.  Anyway, I started Titanium Backup, froze the LG update apps, opened root explorer, deleted the SystemUI update .apk in '/data/app-system' (couldn't be uninstalled from App Manager), and rebooted.

Guess what?  Problem solved.  Now if only I could fix the disappearing lockscreen without resetting the phone.

I'm still running the factory ROM, with a few minor mods, in case you're wondering.

Yea, I kinda knew this was gonna happen. I will try to remove the updater app and see if that fixes any of the issues, I just don't know why LG would find the need to update these 2 apks on an over 3 year old phone.

Good luck with that, it might break the keyguard if you do.
