I keep getting a message on the LG startup screen, that says,
"secure booting error
cause: boot certification verify"
My phone was rooted using king root almost 6 months ago, and I had no problems with it. Until around a month ago, it started getting real slow and apps would randomly stop. So I decided to format the phone. There weren't many problems after that. but after a while it started getting slow again, but slower than the first time. One day almost every app closed and "LG Home" would close, it would give me some kind of error. I turned it off and tried turning it back on, but that's when I got that error. At first i thought my phone was bricked, i still sort of do, so I tried several methods. I can only turn the phone on in download mode, and my computer recognizes it as an android device
At first I had some problems because i couldn't find my right .KDZ file, I used KDZ Update and I tried using LGFlash tool, but i can't find any of the files (.bin . dll) I need. I've also tried using the 2014 version of the LGFlash http://forum.xda-developers.com/showthread.php?t=2797190&highlight=100 Also used the LG Mobile Support tool, and nothing! They all take around 4 to 5 hours to finish!!! It never says there's an error or anything, none of them do! They always finish successfully, but the same thing keeps happening. Every time the phone reboots, it gets stuck on the LG logo and i get the "secure booting Error"!! What else can i try? Any suggestions? Am i missing something? All drivers are installed correctly and I've tried on windows 7, 8 and 10! Is there anybody who can help me? What do you think the problem could be? What causes the "secure booting Error!"??

HI Guys,
I've seen similar threads, so I'm sorry if I'm adding clutter, but I can't find anything that works yet.
Stats:
LG Phoenix P505
Android 2.0.3
Windows 7
I tried to do an upgrade to CM10 a while back, and I almost bricked it. I found this thread and tried it several times. Not sure if it worked or the phone corrected itself, but it was communicating with my PC.

Now all I wanted was to do a ROM backup with ROM Manager. That's it. Just thought it would be a good idea to back up the system. I select the operation and the phone reboots (expected). First I get the LG screen (normal), it skips the LG animation screen and goes to the Service providers animation screen, and gets stuck in a loop. I let it go for almost an hour in case it was actually doing the backup, but figured it should have been done by that time.
I reboot several time and ended up at the same place. I then tried to do the above thread again, but at the command prompt it kept saying, "waiting for device". I uninstalled the LG drivers and re-installed with the same results.
Any help appreciated. Thanks.
Greetings.
I have LG L4 (E440), and recently it got in Boot Loop (after I installed some programs it just turned off, and whenever i try to turn it on, it just shows LG Logo, then LG Animation and starts just repeating animation). At first I was quite confused because I didn't know how to enter download mode (you have to hold both + and -). I thought that was the only problem i was to encounter, but i was wrong.
- I first downloaded LG Support Tool, updated drivers (a lots of them), and went into update mode. Everything seemed OK, but at third step (Software Upgrade), program would stop at 5% and it would give me message like "Disconnect, Remove Battery, Connect, Retry". I tried all of that multiple times, and it stopped at 5% every single time.
- Then i decided to download LG Flash Tool 2014. I took 5 Firmwares (V10E, V10F, V10B, V10C, V10D) and each one of them failed at 5% (one of them failed on 3%). I tried both 3GQCT and CDMA, and all phone modes (EMERGENCY, DIAG, CS_EMERGENCY). None of those worked.
Each time Update stopped at 5% it was because of -
drivers\mstrgen.sys file search fail.
(log is in attachment)
Looks like this driver is missing, or being corrupted. I found out that it comes with MCCI Firmware Update Driver for MTK, but the only one i could find on Internet is giving me "Install Fail" each time i run installation.
I had not as nearly as much problems unbricking LG P970, and i need this phone unbricked fast but i'm all out of solutions Any help would be appreciated!
Hello everyone,
I am brand new here and I have been searching for a solution to my current problem for over half a day now with no luck, and I'm hoping you guys could give me a definitive solution.
I am currently using a LGL22C (LG Power) Tracfone and I've come across a boot loop problem.
During the boot screen with the LG logo, I am presented with the following at the top left of the screen:
ERROR : boot certification verify
[450] ---------------------------------------------------------------
[450]
[450] Secure boot Error!
[450] Cause : boot certification verify
[450]
[450] ---------------------------------------------------------------
(Note: The boot loop continously restarts my phone while having 450 changing into 440 and vice-versa from time to time)
My phone was rooted via Kingroot and I've had it rooted for a little over 2 months. My phone is now in a bootloop due to the installation of Magisk v9. I accidentally installed it using Magisk Manager v2.1, which updated and installed everything that is "Magisk", which then prompt me to restart (which I did), and I'm now in this dilemma.
Again, I have searched for a solution for half a day and I did find some solutions that I thought would work, but unfortunately my phone can't:
1. Connect to my PC (No matter what I do, like update drivers)
2. LG Mobile Support Tool cannot detect nor support L22C model in its listing.
3. Doesn't have Emergency Mode, Download Mode, or Recovery Mode.
My phone CAN in fact go to Factory Reset, but that doesn't do anything in terms of solving my problem.
PLEASE I hope you can assist me. I am truly in a desperate situation.
Thank you!
UPDATE: I just tried to move my number to a different phone (LG Optimus Fuel) which I know that works for the time being. I deactivated it, added my other phone to the plan, but now it's affecting my other phone! I can somehow manage to get it to the Main Screen, but I can't uninstall anything, nor can I use the Phone app, because it states that my Contacts have stopped working (along with several other applications). My other phone has never done this before, nor did it have issues, but it started as soon as I tried to reactivate my number from my LG Power.
Sorry, this phone does not have any sort of recovery options if you trash the firmware. I am also the proud owner of a brick. I've ordered a replacement motherboard from eBay ($15) to perform a brain transplant, and then I'll have to start over.
Hello
I am new to working on these phones so I apologize in advance if I don't properly state any processes or terms correctly.
I have a stock non modded Verizon LGG3 VS985 that experienced problems with WiFi and Bluetooth not working and significant battery drain. This happened right after a recent update to marshmallow. I tried cache clearing, safe mode, hard reset and nothing solved the problem. I decided I wanted to take the phone back to factory condition. I started with the LG flash tool that uses the .tot and a .dll. I ran the flash and when the program got to approx. 80%(at checking mini os phase of the flash) the phone began to reboot and only got as far as the LG logo and after about 2 min of the phone trying to reboot the flash program said fail, usb connect or something like that. At this point the phone will only start and go into a loop that includes the vibrate and the LG logo. and that will cycle until I believe the battery would die if allowed. I then found a link here at XDA (https://forum.xda-developers.com/verizon-lg-g3/general/guide-flash-to-stock-10b-kdz-method-t2928140) that uses the KDZ method, was well written and easy to follow. I ran it on the phone and it was going great. The flash program got to 88% and the phone went into the boot loop with the vib and LG logo . The flash program continued to run until it was complete while the phone was in the boot loop and it got to 100% and said that the software installed. I powered down the phone via battery removal and now when it tries to boot it vibes, shows the lg log and then the green android symbol shows for about 2 seconds and then it does it all over again. I have tried a hard reset and nothing changes. I appreciate any ideas any of you may have on what I can try to get this resolved. Thank you.
