[Q] Secure Booting Error! Cause : boot certification verifty - Sprint LG Optimus G

I tried rebooting to recovery but somehow I ended up stuck with that notice. I can reboot to system. I just can't possibly access recovery. Any idea how to solve it?

Can anyone please help me out or guide me? I've been googling it. Nothing lucky.

Try this. http://forum.xda-developers.com/showthread.php?t=2230106
Or you may have to use the whole bin file
These are your only option.

Did you unlock your bootloader? if not, go back to stock with lgnpst and unlock it with freegee app from play store then flash custom rom again. good luck!

No wonder. Yeah, my bootloader is locked. Do I have to unroot it and unlock it with freegee? Sorry, what is lgnpst? I've obtained my new LS970 today.
EDIT: NVM. Thanks for the link, engine95.
EDIT:: Now I can boot into recovery mode. MANY THANKS!

Bootloader troubles

I tried unlocking the bootloader using android sdk. Didn't work. Im using mac but I couldnt get passed a specific part. Anyways, I found that I could use freegee to do it, but how reliable is it? Is doing it via the laptop more reliable than the app? How often does the app fail? Do I need an unlocked bootloader to install twrp? I can only imagine that I should have a custom recovery before unlocking right? So so many questions....sorry. lol

The app worked like a charm for me. It seems to be the easiest way to get-r-done.

I tried freegee but it hung up on me. I had a soft brick but was able to flash out of it.

But how do I flash out? I dont have a recovery
I had a hard time getting it into download mode. Had the LG screen only. When I dot it into download mode I used the LG utility to flash.

Scared to unlock

So, I'm on my second Optimus G. My first one was rooted but then I decided I wanted a new ROM and tried to unlock the bootloader using freegee and I was bricked...now, I'm about to root my second one but I'm scared to unlock it because I don't want to get bricked again. Is there anyway other than freegee for me to unlock my bootloader? Is there anything I could've done wrong that caused it to brick my phone???

Teeny bins. But you'll need to use them with LGNPST.
FreeGee has a special unlock in it's menu. Open FreeGee hit the menu button. It'll show an sbl unlock and ask for a code that'll be generated.
That's your 2 options.

I'm pretty sure I didn't do the special unlock last time so is that what could've bricked me?

Possibly. From what ive heard, it's becoming the norm to use the sbl unlock.
autoprime says that FreeGee and teeny bins do the same thing. Just deliver it different ways.

Recovery

So ive rooted this fine device with framaroot and.have flashed both twrp and cwm a couple timea as well but cant seem to boot into them. It just gives me a black screen with a measage about recovery security. Did i need to unlock before root? Kind of strange to be able to successfully root without unlocking.

I'm guessing you're on stock. I've never heard of that.
So you unlocked using FreeGee?
For this phone, TWRP is your best option. Makes me wonder if CWM has caused that error.
You could try installing TWRP thru goomanager.
Or, run FreeGee again, and install with TWRP.
Or you can use teeny bins with LGNPST.

Run freegee to unlock or the secure boot certificate, not matching what it should be (partition sizes/md5 or whatever security they use) will prevent you from going anywhere besides normal boot

Ahh, i was not aware it was just a simple app that could unlock. I get the following message attached in the screenshot, though. Is it safe to proceed?

It's fine. If you get an error then go to the irc and talk to them about it and they'll help figure out what went wrong and how to fix it but if it errors out don't reboot

Thanks, much appreciated. Now to find a rom that's better than stock becuase i actually enjoy stock on this phone.

Try Nexogen or the Optimus ROM. We only have a few stock options, but they are all good.

because it doesn't support KK yet, use autorec its easier to get twrp and keep download mode.

I like this app. install it, choose your recovery, and let it do its thing. or you could use Odin, bit this is way quicker.

Get TWRP Coordinator from the google play store, it's a lot better than rom manager and it works perfectly,.;.. (free app)
Give it a try.
Good luck!
Every time I try to install a recovery and boot into recovery mode it bootloops on the note 3 screen. Any ideas

what is your current firmware, and did you try the link I provided above? and also did you try both philz touch, and twrp ?
I don't see any links anywhere in this thread. Is it in your signature for the advertising (web) interface?

I used rashr flash tool. When I tried to reboot using the app it didn't work but when I did it manually it worked. Thanks guys
