Help Can't pull down notification bar on G3s

[Munky999]

I recently factory reset my G3s [D722]. Since it rebooted I cannot pull down the notification bar, also the softkeys at the bottom of the screen do not work apart from the back key.

Also every time I reboot the phone goes into setup mode [enter wi fi code, google account, etc]

Running Android 5.0.2. Rooted (via king root) but I have never been able to boot into recovery using Vol Down + Power or Rom Manager.


Can anyone help??

Did you recently root your device or has this just started to happen recently?

Any major updates you performed recently?

Sounds like something is messing up with the software side that you might only be able to remove with a factory reset.

Let me know more information and I might be able to assist you more

How did you factory reset a rooted phone without going into recovery?

 

[Munky999]

Via 'Factory data reset' from the settings menu.

Via 'Factory data reset' from the settings menu.

That's a no-no if your phone is rooted. That will make the phone wonky, possibly break root and cause issues.

Edit: Nevermind. Saw the model number.

Your best bet is to find the original firmware for that phone from LG.

You've not messed with any system files? In particular one called SystemUI?

Your best bet (as has been mentioned above) is to use a kdz file and flashtool/LGUP to return to stock.

You can get a kdz file from here: http://devtester.ro/projects/lg-firmwares/

Thanks for your help guys. I haven't messed with any system files, just did a factory reset.

I got the .kdz file from the LG website and LGUP.

The problem is I cant enter download or recovery mode. Using hardware buttons just doesn't work. Using Quick Boot I get the following message:

Secure booting error
Cause: boot certification verify

Are you confusing the bootloader with download mode?

On my G4, I turn the device off, hold Volume UP, have a USB Cable plugged in to my PC and whilst holding Vol Up, plug the other end of the USB Cable in to my phone.

How are you doing it?

 

[Munky999]

Thanks @El Presidente . I had been pressing Vol Down + Power as I'd read elsewhere for G3. Hadn't seen your G4 method.

Just tried it, went straight to Updating Firmware but after 25 mins was still at 0%.

Is that on the device itself or flashtool?

Is flashtool set up correctly? There's a bit more info and some screenshots here: http://forum.xda-developers.com/showpost.php?p=53452990&postcount=1

Also make sure the software version you're trying to install matches or is above the version on the phone currently. LG introduced something called anti roll back on the G4 which means you can't "downgrade" via a kdz/tot file.

Kinda stumped otherwise, I've only ever had to use flashtool once and it went perfectly.

If you don't get any joy, post back and I'll tag the person I always tag when I see someone having issues with an LG.

 

[Munky999]

Sorry my fault. I hadn't installed USB drivers!

I've now run the upgrade. It went through the whole process and said the upgrade was complete. But now the phone is stuck in a bootloop and I can't enter download mode.
I'm thinking maybe I flashed the wrong version, there was more than one option on the LG site for G3 S UK Virgin!

 

[Munky999]

OK I've got into download. Gonna look again and try a diff software version

If you put your IMEI number in, it will give you the correct version as far as I can recall.

You can't get in to your phone, but if you still have the box, the IMEI should be on there.

Also, if you're Virgin, did you get it via Virgin or somewhere like Carphone Warehouse?

 

[Munky999]

All done. I found the version I needed on the devester link. Phone up and running. And I've rooted again.

Thank you for all your help.

Excellenté, glad you've sorted it.
