Hello! I have a problem which I don't know how to fix, so I need some help! I'm running stock android 4.4 (20a) and have flashed CWM through Flashify, but every time I try to boot into recovery, I get this message:
"Secure booting error
Error: Boot Certification Verify!"
Recovery worked in android 4.2 (11g), but I messed my phone up, and flashed the latest .kdz-file for my phone. It was after that the recovery-problem appeard.
I've read some places about people with D802 who has this problem, but the fixes they've got only works for D802 and D800. So, how can I fix my F320S? I guess there are more people with the korean version who has stumbled upon this problem, so if you got a fix, please post it!
Excuse my typos if there are any!
Thank you!
LG G2 F320S
Put phone in download mode, and flash the stock KDZ.
If you cannot do this, then you are hard bricked. I had an LG Optimus G which I got a Secure Boot Error after flashing a compatible ROM using TWRP, and although it could get into download mode, it would never be seen as a COM Port in the computer again to it couldn't be seen by the Flash Tools software to restore KDZ.
But it is a stock image I've flashed... What causes the problem!?
Edit: I tried to put it in Download-mode, but the secure-boot error apeard there too... But the phone can't be bricked, as it's booting to Android and everything works...
Would this fix it if the developer made a version based on my aboot?

Edit no.2: I pressed the wrong button-combination, so yes, I was able to access Download-mode, and it works like a charm!
Send with my LG G2 F320S!

Did you ever fix this, and how? I just stumbled on to the same problem the same way. I've got a D802 international. Recovery is corrupted with the same error as yours. That was nonsense about being bricked above. I hate that when people give wrong info. Any help definitely appreciated.

I did not, but I've read a place where devs managed to roll back just the bootloader and in that way access recovery!

I'm wondering what happens if I do a factory reset? Trying to get up the nerve to do it. If not then I think the next best option is to wait for 4.4.3 or higher.

I don't think a reset will fix it as it's not fixing any corrupt data. The problem lays in the bootloader. It's not able to boot into the recovery installed as if it was an earlier build. It looks like this is what you are looking for to be able to install a recovery the right way. I haven't tried it yet, tho.

It worked! I took the plunge and it worked immediately. I've got TWRP. I already had root so did not have to use the iroot. I just ran the autorec.apk and problem solved.

I have T-Mobile LG Optimus L3 that was rooted with Kingo without a recovery (I'm a noob). A while ago my phone became irresponsive so I hard-reset it( also because I'm a newb). When I was done, my phone was stuck on bootloop. It would get to the white T-Mobile screen then loop there. I tried using the LG Mobile Support Tool but an error would occur at 4%. I don't know what to do. Can you please help.
It's no big deal.

Try using the KDZ method to flash your phone. So it will be back to it's stock ROM. You can find the KDZ update method here
PS. If you still have doubts I could walk you through. Cheer up!
Different problem here... e400

OKay. So you tried out differrent things. But if you could explain briefly why the KDZ did not work for you, it will be much easier to solve the puzzle.
Could you get your phone in emergency mode?

If the phone is not turning back on even after the KDZ update, then chances are that you have hard-bricked your phone. In the KDZ update, does the log says 'UPDATE SUCCESSFUL' message?.

"Wparam=100; Lparam=6" are errors denoting that the update was not successful. And the 'finished' message indicates that the process is complete. But, it must show that "Update Successful' in the log. Understand that. Try to re-install the LG mobile drivers and then flash it.

thanks for help man, but for me the only way was send it to service center...
it cust me R$140,00 (US$70,00)
Alright dude. Glad for you!..
So first of all a little bit of backstory: I tried using TWRP on my phone to install a supposed CM13 rom that actually ended up bricking my phone, but I had made a full backup beforehand in case something like this happened, so I restored the backup via TWRP and nothing, so I thought to myself I'll just wipe my phone and install a stock rom, and so I did, but nothing, the phone was stuck in a bootloop on first launch ( I left it on for about an hour just to make sure). So I used LG Flash Tool with a .dz stock rom for my phone but still nothing, I also tried the official LG tool but the result was the same. I have access to download mode, fastboot and can factory reset the phone, I tried factory resetting it but nothing. So I assume my phone is bricked, how do I unbrick it?
I'm using an LG Magna H502Y Dual-Sim and has an MT6582 chip

Exactly the same problem here.

Use LGUP and UPPERCUT to flash the stock KDZ files. Google how to get into download mode and a guide. Easy to fix.

laf is gone (the partition that runs download mode) in this state I need some way of communication to the device in edl mode. I know what you're saying to do but there is no download mode to get into ive tried... multiple times.
It 100% works. I've fixed handful phones with this exact issue.

Im not arguing the validity of this technique in most cases this would be proper procedure but my failure happened partway through writing partitions.
the partition map is corrupt and laf is empty there is no download mode to communicate with anymore. very specific to MY device download mode has been in the easiest sense of the situation deleted

Sounds like you got 2 warranty issues now. If the bootloader is locked, LG should honour the repair.
There's a program called QFIL (qualcomm flash) and you can use it to flash a kdz. I believe all it does is flashes download mode as once it succeeds and your phone is in download mode you would then reinstall stock kdz. I noticed there's a mention of 'firehose' though and I'm unsure yet of what that is.
Just curious: how did you manage to remove write protected partition while your bootloader is locked?

I live in India And I imported phone from USA it's a T Mobile Unit. What are the options? Anything can be done at hardware level ? Without changing the entire motherboard?
No. Order an H918 with a cracked screen and clean IMEI off of eBay (actually it doesn't even have to have a clean IMEI, you can use the one from your current phone), and replace the board.

Board replacement is the only solution ?

The above is still true, if this didnt happen immedately after/during rooting/flashing something or using a dd command (while also rooted) your board is dying and you need a new one.
