[Q] LG G3 security error

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

zenfone 2 boot loader shows usb icon

Hi All,
I need your help :crying:
I have Asus Zenfone 2 ZE551ML which was bought couple of months back. Since it had lots of bloatware apps, I thought of installing unofficial cyanogen mode 12.1 os in my phone. Though the installation was successful, I was forced to uninstall this too early as it had too many bugs.
As a initial step I tried to restore the original recover and I was successful. But in between I tried flashing the boot and something went wrong. Now I am unable to go to the boot loader option - it always shows a 'usb' icon. I tried with power button + volume button combinations, also I tried adb reboot-bootloader but no luck. All these options took me to a screen where it shows just a usb icon image.
Could you please help me to restore the boot loader ? Also please help me to restore my original firmware.. Please...:crying:
Appreciate your efforts.
Seby

hard briked, same here, hope somebody here on xda can help us

It sounds like you flashed the wrong image file on boot partition... Beware copy and paste when doing this...

Take back to ASUS and hope it will be replaced under warranty....

Similar tragedy happened to me few months ago. Flashed the wrong file, and the recovery partition missing. On zenfone 5. Somehow the phone still boot with cm12.1. Tried everything, still unsolved. Not yet tried asus service centre. So i give that phone to my sister, and i bought this zenfone 2. Lesson learned. ?

xfstk-downloader
The only way out is to use xfstk-downloader. But the problem is in missing required files FW DnX, IFWI, OS DnX, OS Image files. Especially last two of them which can't be found in firmware files. Same solution already exists for Zenfone 5/6

Phone stuck in bootlop, can't enter droidboot

Hi guys ,
a bit of a novice here , i have the ZE550ML edition and have tried rooting my phone
the steps that lead to this problem are as follows
- tried to root the phone using one of the utilities on this forum - kept getting error messages saying not allowed to write on partition
- tried to unlock bootloader by using one of the utilities on this forum - failed and device was stuck in bootlop but could enter droidboot and recovery , was detectable as moorfield on the pc
- tried to flash the official rom image using asus flash utility and now stuck in bootloop but can't enter droidboot at all , my pc does not discover the phone anymore either
is there anything i can do further to fix my phone or am i screwed ?
sorry if this was already posted , i tried to find answeres on older posts but nothing help

if you are not able to go to recovery of fastboot mode. following is the only way to get out of it. read carefully. do as suggested. go to other point after completing one properly. do not use asus flash tool after you enter fastboot mode. use commands to flash raw firmware. see section flash firmware without AFT. OFC after you get fastboot mode back.
