Hi All,
I have a problem with My lg G4 H815T.
After an error upgrading with LG Bridge I got Boot loop with message 'Secure boot Error 1003' , I tried to flash an older ROM with LGUP but could not get into the download mode for the same reason 'Secure boot Error 1003'
Can any body tell me how can I fix this problem ?
Thanks in advance

Downgrading isn't a good idea btw. Upgrading is another thing but downgrading can give you results like this.
Are you able to go into the recovery mode? You could try a hardware reset from there.

Thanks for replying.
Yes I can get into the standard LG recovery mode but when I choose to do a factory reset it shows me the same error message (Secure boot Error 1003) and reboot again.
My lg transpyre does the same thing. When you're in factory recovery does it say modified at top left corner? Mine does and when I select any option it just freezes on that screen saying secure boot error code1003 top left corner

Just got the phone today and successfully rooted it and I wanted to see what this xposed framework stuff was about I installed the experimental version (tbh did really read it was experimental it was on the front page so I thought it was alright) and when prompt to reboot I did, but now when rebooting I can't get passed the Lg secruity error screen I tried re-flashing back to stock using this thread http://forum.xda-developers.com/showthread.php?t=2799647 but nothing happens after I plug my G3 back in it just says ready is there any other way to fix this security error?
edit:found out that my model number is actually the f400s (sorry i'm a phone noob) for anyone else out there trying to find your phone model it's actually behind the battery

Again I ended up resolving the issue myself and I do not have a picture of the error but I can describe it. When booting my lg g3 the normal big Lg logo appeared then after a bit a smaller lg logo appeared with the words "security error" under it for those looking for a solution to that problem the thread in the op is the correct action to take to resolve the issue. Note doing that wiped everything on my phone which was not a big deal for me but I had to take my phone back the the carrier to input the configuration to access 4g lte again & it unrooted my phone.
i have this same issue can you tell me how you got around it?

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.
Thanks man. I actually could get into recovery so I just flashed another kernel

Please any help will be appreciated and thanks

http://forum.xda-developers.com/showthread.php?t=2797190
So I was trying to install TWRP on my freshly rooted V500 5.0 korean kdz, followed the steps exactly and I tried to reboot to recovery and got the
Secure booting Error!
Cause: boot certification verify
Reading through a few other threads, I tried going into download mode and upgrade recovery through the LG mobile support tool, but that says no items to upgrade. Now, my tablet will not boot up past the error screen and I'm having no luck finding any way to get it booting. Any ideas? Thank you in advance for any help!!
EDIT: KDZ back to 10a
Same here!

Hey,
My phone just got stuck and won't load up, but I have access to "download mode".
Is it the famous motherboard issue?
flashing an official firmware might solve it?
Thanks,
Hezi.
Can you go to recovery mode.if you can try to wipe data and cache.
After doing this if it not work so try flash official rom
no recovery

you can try it if no go, then contact carrier or LG get it fixed.
just gave it to them and waiting for an answer.
I have a warrenty for 12 monthes and 13 monthes passed since I have bought the phone.
Does LG policy is to fix it in any case?
Moreover my bootloader is unlocked..
Have you tried flashing the official Rom using LGUP?
tried, didn't work
You just download Lg Bridge and turn on the phone in download mode.. You will see in Lg Bridge that you have recovery option .. Hit that and it will download latest firmware for G4 and install it .. This will wipe all your data
ok but whats the difference if I flashed the firmware via download mode.
either way I am now waiting for a response from the lab.
