I think I bricked my phone and it is not turning on. I can see the LG logo coming up on the screen but it doesn't go beyond that.
I see some small error message on the Top left corner of the LG Logo screen. Once the that screen is off I see Blue and Red LED light blinking.
Someone please help me.

I will spare myself from answering the question for the third or fourth time? and just quote myself.

jerimynal wiley the error you get "secure boot error" is caused by image you are trying to boot not being bumped or not properly flashed. I assume you get this error both while trying to access recovery and OS. If that is the case you should use this guide:
http://forum.xda-developers.com/showthread.php?t=2785089&nocache=1
to flash stock firmware on your device.
But if you have a case where you are able to access your recovery (TWRP I assume) you could use one of the custom images provided here: http://forum.xda-developers.com/lg-g3/development (assuming you have D855 version) . Flash them and use them as OS.

hey guys i really need your help. here's the detailed story:
I've got a D855 on 5.0 that has just been recently been rooted. It's been working perfectly until just a few hours ago i wanted to try enabling the build.prop edit to enable all applications to be usable in split screen mode. so i just switched the related value from false to true, saved changes then reboot.
This is where the problem starts:
When trying to reboot, it just shows the LG logo briefly.. the LED lights just light up and switch from green to blue and loop over and over while the screen is blank.
I tried doing the factor reset on boot (power + volume down, release on power on then re-press again), but when i choose to factory reset the phone a short message on the top left appears ("Secure Booting Error! Cause : Boot Certification Error" - or something like that) then the screen goes blank and the led flashes from blue to red and on loop.
How can i go about making this thing work again?
Thanks in advance! Any help would be greatly appreciated
shameless bump
Can you get TWRP? If yes and have backup build.prop or ROM, flash it.
If not, can you get download mode? If yes flash KDZ.

You need to download a KDZ file for you D855 from a site or XDA thread
Then use the LG tool to flash the KDZ and then your phone should work as it worked before. I've had this issue before. Fixed it this way

thanks, yeah it was the only way i was able to bring it to life.. was able to fix it yesterday by using the TOT method.
Another question: it seems that after flashing the TOT file (i used the UK version), i can't enable LTE anymore. when i try to enable via settings, the signal just disappears. when i go back to the home screen, it gets restored but only up to "H/3g", and when i go back to settings it goes back to GSM/WCDMA.

You need to change your APN settings. Look on google for the LTE APN settings for your provider

Could somebody go over this KDZ stuff? I never used it before. I have a G3 850 with a black screen. It will boot, I get sounds but no visual anything except for LED, it flashes blue and green.
Hello,
i have messed up a bit while rooting my LG G3 but finally everything went smooth and i even had TWRP installed (hurray!). But now i need to go to stock because i need to get my phone fixed on warranty. The problem is that when i press Volume Up and plug in USB cable i see on screen: download mode, in the left top corner there are some little words "boot certification verify..." and then everything goes black and there is no 2nd step Download Mode screen.

If you enter this video you will understand me. I can see the images which are in 1:03, but right after everything is black and i do not see "Firmware update" images in 1:14.
How can i fix it?

I made the exact same thread not long ago but NO ONE helped, sadly...
Got the exact same problem as you, I got no choice but to send back my phone for repair!
I completely messed up my bootloader... I tried reflashing etc, it even got worse (no TWRP, nothing, DEAD)
On the report they wrote "flash failed" and they eventually replaced the PCB (the main board).
Was lucky that they didn't charge me anything haha
either they didn't know anything, or they were nice with me lol
If ever you send for repair, Just don't mention you flashed or rooted or whatsoever lol ...
Hello to every one!
I have a problem with my LG G4s H736.
So, I got root rights with KingRoot on 5.1.1 android, after that i changed to SuperSu via SuperSumePro.
Than i wanted to update to Marshmallow via LgFlashTool. When the process bar were on 5% percentcs, electricity turned down.
After that i tried to turn on my phone and i got a endless reboot, Lg logo appears and then disappears whith a little blue flash on screen and all that repeats endlessly.
PC does not see my phone anymore. I tried to revive my phone via LgBridge, but it wont help me BUT after pressing button "repair after incorrect update" i started to see a little message in upper left corner:
boot verification failed!!
cause mismatch_slg_len
What can I do with it? Please help guys!
Thanks for your attention!

will flashing a KDZ work.? have you tried.? is there one for this phone.? if its bricked then LG should fix it tell them that.. what happened.
My one plus 5t is stuck on logo after an official update and the bootloader is locked.
Is there any way to unlock bootloader without access to OS (OEM unlock), so that I can flash any custom recovery?
Or any other solution from experts?
Use fastboot to OEM unlock.
Read up on some tutorials, this one is easy to fix.

I read this but they are saying that you have to go to setting and developer option to enable oem unlock first, but i cant access to my device because my device is stuck on logo screen.

I would suggest you do this first:
https://downloads.oneplus.com/oneplus-5t/oneplus_5t_oxygenos_5.1.1/
Then you should be able to boot to android again. Then tick the OEM lock button
Just enter stock recovery mode and do a wipe factory reset. If it doessnt work, just falsh official oxygen os and do the factory reset again.
If the reset doeesn't work there is a cheat that will work if encrypted and your data is backed up... Open the stock recovery which will require a password. Select the dont remember button at the bottom. It will warn you that procedding will wipe your phone. Do it. The recovery will wipe and reboot your phone with the stock image you just tried to flash. You WILL lose data.
If you cant access the stock recovery or TWRP you can boot either on your PC and perform a wipe from there. You can then move a stock image over to root and flash it with the stock recovery.
I have this same issue, stuck on one plus logo on boot. Can enter fast boot menu but can not enter recovery mode.
Do you still have that problem?

I am having the same issue. After the android 10 update and after my first restart, it gets stuck on first android boot screen. Not ever the oneplus screen is shows and phone screen becomes dark with led on in grey color. I tried wiping the cache and did a factory reset too but it did not work. Help me what to do. Also where can I find android OS image list of 5T and a process to flash it through PC (ADB commands may be or something else?)
Someone pls help me. My Oneplus 5t stuck in logo screen & not moving to any further screens.
1. Switched Off the phone
2. Now turning it ON & logo screen has come
3. After 5 to 6 seconds logo screen disappears & white LED indication starts glowing.
Pls suggest what to do.
