[Q] Secure boot error - LG Optimus G (International)

hi all! I've certainly royally screwed myself over this time around.
I installed sling v3.2 and restored my apps, after restoration I tried to unlock bootloader with freegee (since it was pre-rooted) and freegee showed it was already unlocked, so I tried to flash a custom kernel and viola! this happened!
Problem is, my power button is close to broken and no amount of pressing down will turn the device off. is there anyway I can turn it off or save my Optimus G? thanks in advance!

UPDATE:
I've tried to get into download mode but to no avail (tried pressing volume up + down while ramming the power button on my PC desk). I tried Vol Down + Power and I got into factory reset mode, so i pressed vol down because I didn't want that.
It restarted to LG screen which showed that dreaded secure boot error message. This time around I tried Volume Up + power button and it restarted but with the message "something unLock!! restart boot!!" something like that, didn't really see what it was, it flashed too quickly for me to see what it said. Anyways it then rebooted into CWM and now I've cleared cache/dalvik/system/data and re-installed Sling v3.2!!
Hopefully this will work out so I'll update this when it finally boots back to life! (hopefully!)
BTW, my device is an LG F180K the Korean Variant, it's color Maroon with an Olleh logo at the back, just in case anyone was wondering.

[Q] sync-problem on 3.4.2-117 UK Froyo

I upgraded from 2.51.1 to 3.4.2-117, and the phone lags, seems to me that it is because of the google sync. Someone posted the very same problem and said that factory reset solved his problem.
My problem is that the phone does not do factory reset, in Privacy I press the erase button and nothing happens.
I tried to boot into recovery, but I can't get into it. The droid comes up but upon touching the lower right corner nothing happens.
When i try to boot with vol up and down same time, the phone boots into safe mode.
How shall I get into recovery so I could do a wipe? The phone is basically unuseable now because of the lags and freezes
Hey mate! Don't give up. When you see the droid in the center of the lcd just push vol+ and vol- at once. You'll get into recovery mode. )))
thx dude, i figured it out "accidentaly"
Everyone was writing on the net that the recovery boot is up and down the same time instead of the old method of power & volume -.
So, when I got to the droid, started to push every possible button in every possible variation and I got in.
since then I learned that the vol up and down is after power & vol -, not instead.

[Q] Help! Can't access fastboot or recovery. Bootloop.

I installed the latest Cyanogenmod 10.2 Nighty yesterday and it worked just fine. I rebooted it and got a cyanogenmod logo bootloop. I entered fastboot, then recovery and installed another version of cgm which was already in the sd card after wiping the data.
Now I can't even access fastboot. When I hold the power button with volume up or down it does nothing, sometimes it shortly shows the LG logo and then it turns into a black screen.
The only thing I can do is to access Download Mode by holding power+volume up+volume down.
Thank you for your time
Click my signature and look there for answers. Use kdz updater to revert to stock and that's it. Don't ask how you do that,i will ignore any further questions. You have all the answers there.

[Q] Bricked, enters recovery mode instead of download

Alright so I have had this phone for well over a year and it has been bricked since I got a hold of it. A friend gave it to me to fix and never asked for it back and since I have had my iPhone I have missed having an android to play with :crying:
It is stuck in a bootloop thing (It shows samsung and when the andorid flies up it freezes and resets) I have been trying to reflash it with odin for ages but gave up and finally decided to seek help after days of googling and searching
If I boot holding VOL + and VOL - , all it does it boot into recovery mode (and I have wiped everything and reflashed the rom on the internal sd card successfully) but it still does the same thing. I have also tried booting in other ways (Such as HOME and VOL +, and HOME and VOL - , but it just goes to the boot loop. I need some ideas because this iPhone is getting broing
Does the phone use the stock recovery? And if you are needing to hold the home button to enter anything, I think you got the wrong forum as the SGH-T989 only requires the VOL Down key to be held to boot into recovery. Are you sure your device is not the I9100?

No ROM, can't access bootloader, stuck in bootloop

Hey guys,
Ok, this is a tough one for you. I'm actually not 100% convinced that my phone isn't hard bricked. But every where I look for, it says, it's only hard bricked if your phone wont turn on at all and that's just not true in my case. So here's the story:
My volume-up button is kind of screwed, I don't know, what happened to it, but one day, it just started being triggered randomly until it just didn't work at all anymore. It wasn't that big of a problem, since I was still able to change the volume by hitting the volume-down button once and changing the volume by the on screen slider. I was running SkyDragon GPE V5.5 for quite a while now.
But now I wanted to upgrade to Android 6.0, so I downloaded the firmware from here. Next I rebooted to bootloader switched to fastboot and used "sudo fastboot oem rebootRUU" and "sudo fastboot flash zip firmware.zip" twice. So far so good, everything went fine and I actually even am able to see the new Google splashscreen.
So now I want to flash this ROM. But, for some reason, the touchscreen doesn't work anymore, even though it's activated in the CWM Philz Touch GUI settings enabled. Alright, so I "wipe to install a new ROM" and navigate to the zip file to install it and it starts the aroma installer, which I can't control since the touchscreen doesn't work. So, I'm kind of frustrated by now, I flash TWRP, because, maybe here, the touchscreen works. I flash it and try to reboot into it. But it doesn't work, it just stays at the Google splashscreen, I can restart by holding down the power button but it will just go back to the Google splashscreen. After a couple of tries I actually get it to turn off, so I hold down power and volume down to get into the bootloader but it just goes back to the splashscreen.
I can't get to the bootloader, I don't have a ROM installed and I can't get into the recovery. Is there anything I can still do or is everything lost?
Which TWRP version ? You need to use 2.8.7.0
You can't get to bootloader because of the timing when pressing power & volume down button.
If you can turn it off, press and hold volume down button then press power button until it vibrates then release the power button.

No hardware buttons work!!

Hi
Could some one tell me why i cant get in recovery or factory mode with hardware buttons, i am on stock 10d with twrp recovery installed and rooted wirh super su through twrp. I installed twrp through adb with normal command and device works just fine through reboot apps from os, boots in recovery,fastboot etc just fine,same through adb commands.
But there's no hardware combo or anyrhing working when trying to enter recovery or factory reset working at all?
Tryied every combo i could find saying how to from internet.
It just boot up in os as usual.
And phone dosen't reset while holding power button for 10s + either
It's a bit scary because bootloop is going to come eventually for sure and then there's no rescuing avalible
Could someone plz tell me whats going on?
Im new to g4 so, some help would be nice.
Thanks in advace
It's a bit tricky, to be honest.
• Power off your phone
• Hold "Volume-Down" and keep your "Power-Button" pressed. So you should keep both pressed, until the 1st LG logo appears
• Now just leave the "Power-Button" for ~1 second whilst kept the "Volume-Down" button still pressed, press now the "Power-Button" again and keep holding it
You're now forced to deal with the standard-ui from LG. Go to "Yes" and again "Yes". TWRP now boots and you should be fine .
Edit: Just my tiny story... I watched several videos and also had a nasty bootloop. I was afraid, I now bricked my phone. But a nice user showed me this way and this was the only way, I got my phone recovered.
