Secure startup doesn't recognize PIN code - LG G5 Questions & Answers

Hi,
I have a problem with my LG G5 (but saw it happens in other LG phones)
I have a PIN screen lock and I changed it a couple of days ago.
I was talking on the phone when it restarted (I remember the battery was hot).
Now the phone is on "Secure startup" and I had 30 tries to unlock it (15 remained).
Can't add link because I'm new, screen from 2017 post on this forum, /showpost.php?p=71690001&postcount=27
I have the "white" screen (and can't get to the "black" screen, more details down).
I saw a number of posts on this issue.
I can only enter PIN (no character keyboard).
I tried the current and previous PIN. Also tried: 0, 0000, 00000, PUK code.
Some of those tried also on safe mode.
When tried to fill the screen with zeros as much as possible and tried to unlock, I got a screen that said something like (translated):
In order to open the lock, turn off the phone and power it on again.
Did it but didn't change. Than I thought I should have pressed restart (instead of turning off and then on) but didn't got to this screen, just stayed on the same screen with one try less.
I can get to factory reset, only this option yes/no (can't add link because I'm new, on Youtube: /watch?v=6rQNENaJYZg)
I don't want to hard reset because some files are not backed up.
Also can get to Fastboot mode and Download mode.
If I restart (or power off and on) the phone is on flight mode.
I can call to emergency numbers, and when I call and hangs up, suddenly there is a cellular connection and 4G data.
In this situation I can receive calls, but still can call only emergency numbers.
The phone is not rooted and I don't use special ROM or something like that.
From time to time it makes tick sounds (like pressing a button) every few seconds. The rest of the time it doesn't make any sound.
The computer recognizes the phone and installs the driver - "Android bootloader interface" but I can't see the phone on my computer.
Also tried to connect through Google Find but it can't locate the phone and the lock option there doesn't seem to do anything (writes request sent).
There is a problem contacting stores because of the Corona.
Appreciate any help,
Thanks very much!
Edit: I also have a memory card, do you know if the data on it is OK? (I don't have a card reader)

[Q] Stuck in Flight mode due to of NFC ring Unlock app

I installed the NFC Ring Unlock application from McLear on the EZ2 tablet, which seemed to function well with my NFC ring.
I did one thing differently, because I don't like to give my Google master password to a 3-party app , I used an app password specifically for the NFC ring, which I considered to be one-time and didn't write it down
Then I had to fly and put the device in flight mode and powered it off some time later.
Now I get the NFC Ring Unlock screen in flight mode when I power up the device, but I can't get the unlock screen to work (NFC is also switched off in flight mode, didn't realise that and the Google authentication is also not working) and I can't get out of flight mode!
What I tried already:
Resetting the device by voulume-up/power, red button in SD-card and PC-companion connection.
Trying to hit the "normal" unlock screen which appears for a sub-second period.
Contact McLear, but they are flooded at the moment, because of the roll-out of their new products.
But neither of this works because they all depend on unlocking the device first.
Any advice?
If your device is unlocked and you have USB debugging enabled, you should be able to deinstall the App with ADB (Adcvanced Debug Bridge).
I guess that with the locked original Sony Bootloader, this doesn't work, though.
You could do a remote wipe with play device management:

If Sony's software detect it when you connect it to computer, you might also have some options there. I am using Mac and only see repair device ,under the Xperia menu, as a potential solution.
Hey Svan, damn it sucks you are getting stuck by this! Sorry!
1. Did you try posting on the NFC Ring forum?
RE "3-party app" our app never stores your details, we use the Google provided Google Auth libraries to handle the authentication process. I can personally guarantee and promise at no point do we store or use your username/pass, we just get a success/failure callback from them and act accordingly.
2. Is it possible you can use your Google Auth or is your work-around preventing you from doing this?
We're actually just beta testing an updated version of the app that forces users to enter a pin code to handle circumstances such as this. Flight mode and two-form factor auth have been an issue for us so we're taking pro-active steps to address it ASAP This doesn't help you though ;(
3. As BabelHuber asked, do you have debug mode available? If so a simple adb uninstall of the app will get you moving again.
Sorry about the delay through support, I just took another team member on today to help with the backlog, he starts tomorrow so hopefully things will move faster!

Found a solution
I had a the exact same problem, and luckily I found a solution just in the moment I had already decided to factory reset.
I have the stock rom/bootloader/etc installed, no root.
Well anyway, factory resetting the phone is not an easy task either, so this is what I did to get to the factory reset option in the boot loader:
I pressed power for a loooong time, then the phone shutdown, I pressed power and vol-down for a looong time.
Some kind of boot menu appeared, I chose recovery.
At first I was stuck with a red triangle with an "!" over a lieing android. I found that pressing and holding power for 1 second then, while still pressing power, pressing "vol up" for 1 second and releasing both at once, presented me a special menu, wich contains the factory reset and option ... and also a mysterious "wipe cache" option, which sparked an idea of how I might circumvent the factory reset...
I remebered, that after the last OTA update the phone was so busy after reboot, that the NFC Unlock app was loaded after a long delay, while I was already able to interact with the phone.
So I though what the heck, before factory resetting the device I might as will try wiping that damn cache and see wether that caused the delay.
After wiping the cache, I booted and Android went through all those apps, and then showed the launcher/home screen without the widgets loaded etc, for just long enough to switch off the airplane mode, before the unlock app was loaded and immediately locked the screen again.
It might have helped that I disabled the SIM Card PIN check, i don't know.
Only this time I could unlock it normally :silly:
I hope this helps

Stuck on PIN screen after flashing to Nougat

A few minutes ago, my Z5 compact finished updating Android. When I turned it on, it would accept the SIM-pin number no problem, but it will not take my phone PIN. The four dots show up when I enter it, but it will not unlock the phone. Since the PIN is required after a restart, that leaves me in a pickle because I can't open it with a fingerprint either.
Is this a common bug? Does anyone know how to fix it?
(Edit: The phone is working. I can see notifications coming in, and can delete them, but the phone still won't accept my PIN. Even after a restart.)

Help me with my phone(Keyboard is not appearing and turned into emergency mode)

Hi,Brothers
I have a serious trouble with my phone.
My phone's model is sm-g5108q(SAMSUNG G5108Q Galaxy Core Max).

I googled my issue all day long, so i found solution. That's the way to use usb-key board(with otg cable)
After i connected usb-key to the phone (with otc cable), but nothing happend, I disappointed.
I tried it on other phone, usb-key works well on lock screen on that phone.
I looked thorugh my phone,omg, my phone turned into Emergency mode(i don't know the reason).
In Emergency mode, it didn't permit to connect other device to save battery.
I googled again to find the method to disable Emergency Mode.
On Recently produced phone, after pressing power button, there was a menu "Enable/Disable Emergency Mode".
But my phone is old one, so in order to disable Emergency mode, i think i should login my phone.
So i can't do anything.
To use usbkeyboard, i should disable Emergency mode.
To disable Emergency mode, i should login phone.

Please help me, i will appreciate any solutions or advices.

Pattern stopped working

Hey!
I have fingerprint and Iris along with pattern on my phone. Suddently while using the phone, it stopped accepting my pattern (which I use daily, and no, I don't have a case of amnesia). I was dumb enough to restart my phone as some suggested that made the phone accept their pattern again, but now, of course, I'm completely locked out.
-I've tried findmyphone.samsung.com but it only say I haven't activated the unlock feature.
-I've tried entering "adb shell" and then "cd /data/data/com.android.providers.settings/databases" but get "Permission denied" (while on the lock screen)
-I usually get 3 tried on the pattern, but now I only get 1 try then a 30 second timer.
I really don't want to factory reset via recovery (would that even help?) as I have so much data on my phone I don't want to lose.
Is there ANY way to get into the phone again? This is REALLY frustrating as I'm now locked out because the phone got bugged and suddently, seemingly forgot my pattern. SAMSUNG support claims that it's not their fault that "I" forgot my pattern (I remember it like night and day), and also that I don't have the "setting" for 3 attempts activated (when I clearly do, which I know as I get the prompt daily due to missing a point now and again). Their suggestion is that I turn the phone in for service, but the problem is that I'm catching a flight and moving out of the country in less than 2 weeks, and there is no shop even remotely close to me, so that isn't an option..
I have bills to pay too, and the bank security app is also on my phone.. /:
PS! My phone is not rooted.
Nevermind. I just factory reset as I figured I had a backup. Later (too late) I realized the backup was from November, and that I COULD have made a backup via findmyphone.samsung.com FIRST. So if anyone has my issue, just go to findmymobile.samsung.com and backup, then boot into recovery (reboot, hold bixby button, volume up and power button down, and release power button when the samsung/knox screen shows up), then wipe data. Later you'll be able to use your backup to recover your data and apps.
