Samsung S8 issue after update - Samsung Galaxy S8 Questions and Answers

After the most recent update, the phone got stuck in a loop with a message ‘Your phone is encrypted, enter your PIN’. Entering your PIN showed the lock opening but it took you back to the same screen. I tried to boot it in safe mode and it was showing a message ‘Optimizing apps’ and then it went black and died. It won’t turn on in any way even in a recovery mode. Connecting to a PC shows the Qualcomm as a device but doesn’t recognize it as a phone.

FRP ON + broken bootloader

Hi, got my OEM disabled, restarted phone, couldn't do so. Basic story. Tried the Emergency Software Recovery via Kies 3 and Smart Switch, but the problem is the blue screen with triangle keeps blinking and the phone plugging/unplugging. Since that's been so, I can't finish the process properly. Any idea how to prevent it from blinking? I can get an access to bootloader only for a sec, then it proceeds to the triangle screen.

My LG G6 is in a secure screen loop.

So today i bought my LG G6.
There was a software update (i thing Oreo update) i installed it and when i got to the secure screen on the boot.
I type my PIN ,which was valid and my phone now is stuck on the secure loading screen.
At first i thought it was just going to take some time but after 25 minutes of waiting this started to worry me.
The phone is still on loop and when i use the Power Button and the Vol down the phone restarts but the same thing happens.
I tried everything from restarting it , to hard resetting (which doesn't want to work, the bootloader menu doesn't even show up with all the steps completed correctly) to throwing it on the ground.
(PHONE IS NOT ROOTED)
EDIT:I MANAGED TO SOLVE THE ISSUE BUT NOW IM STUCK AT THE PROVIDERS SCREEN WHICH IS (TIM) AND I CANNOT DO ANYTHING OTHER THAN SOFT RESTART
Regards,
Try put the phone into download mode and use LG bridge to reflash stock [Use the "Update error recovery" to reflash]

LG Spirit bricked. Download Mode stucks on error.

Hello everyone,
It's the second time I have a problem with my LG Spirit but now I seem unable to do anything
About month ago my LG was getting stuck on LG loading animation but then I managed to flash it via Download Mode and LG Flash Tool. Everything went fine and the phone was operational till today.
After battery had gone flat I plugged it to recharge but "Security Error" occured.
While plugged in it constantly shows the error message and reboots again and again.
Of course, I tried flashing via Download Mode but in vain. Although Download Mode shows up, a message "Secure booting error. Cause: Boot certification verify." appears, the screen blinks in blue colour and turns off.
Any PC with any USB wire recognizes the LG. Debugging mode is switched on, but no modifications such as TWRP, etc. were ever made.
I also managed to restore default settings, but with no results.
Any ideas what to do?
Thanks in advance
I saw this thread earlier, maybe it can help you?

My phone is stuck in bootloop and keeps going to an 'erase' screen

I tried to root my device trough odin. Odin said it was succesful, but when i turned on my device it said someehing like 'vertification failed, you have to reset your device'. So i tapped the button 'reset'. Then my phone restarted and its now stuck on a boot loop with the 'erasing' screen. It just goes to a blue screen with the android logo and beneath it it says 'erasing'. Then after a few seconds, it restarts and turns back to the screen again.
I cannot get into recovery mode, because you'd have to do it with the power button, volume and bixby button, but the second i try to do that, it just restarts and starts the loop again. Even when my phone stopped with the bootloop and just shut down, when I hold my power button it just restarts the boot loop... I already let the battery drain but then still, it just happens again.
I can only get into download mode, but thats all. I dont know my build number. I already looked at the box my phone came in when i ordered it, but all I could find was:
- an IMEI code
- an S/N code.
- a long code existing of numnbers only.
None of these codes I think were build numbers, only the S/N code contained letters.
So I dont think i have my build number. I cant get into recovery mode since it just starts the bootloop.
Please help
My phone is a samsung galaxy sm-g950f
I hope my phone isnt bricked and this can be fixed.
hi did you find a fix? I have the same issue

Problem with LG K8 model: LG-K350N (download mode not working)

Hello, I have a problem with my old phone. The phone does not turn on to the system or download mode. After connecting to the charger, it charges normally and then restarts either to the words "Your device is corrupt. It can't be trusted and may not work properly." or to a security error. When I try to turn it into download mode, the LG logo is displayed with in left down corner text downlaod mode, then the message Your device is corrupt…. and it restarts.
When I enter the phone recovery, after clicking the buttons, the same message appears (Your device is corrupt and so on).
Thank you in advance for your help because this is the first time I meet it + there is nothing about my problem with the download mode.
