[Q] HELP!!! Bootloop/Security Error/No Download Mode - AT&T LG Optimus G

So, I hope I'm not completely bricked. I was using LGNPST to flash a stock ROM, and at 85%, the phone rebooted and is now in a bootloop that ends in "Security Error". I cannot get to Download Mode either, nor is it seen by ADB (obviously). Can anyone help?

Try this- with the phone powered off, press and hold down the volume and power key simultaneously. You will be prompted with a Factory hard reset screen. Confirm the actions and you should be good as new.

I did that already. I get the Android, and then it goes back to the bootloop again after about 30 seconds.

Does it show the LG logo, showing security error on the bottom? Which rom were you coming from before you LGNPST?

I was stock 4.0.4 unrooted (this all started because the phone won't pull the JB update OTA, and the phone wasn't showing in ADB to root it), and yes, it's the LG logo with Security Error on the bottom.

So you can still get into factory hard reset mode and then it just bootloops after the reset has been confirmed?

I am sorry that I may have mssed something in your other post. But firmware version 09j is one I have never heard of.

Yep, after a factory hard reset, it still loops the same.

And so I just searched for it. This is apparently a test unit (I was given the phone in a trade), which would explain why it won't pull OTA updates. And is probably why I'm having all these issues. Sonofa...

I think your only option is to restore it via RIFF JTAG... I don't know another way...

yes, from last 2 hrs its on charging.
I donno what is RIFF JTAG and Qualcomm diagnostic mode
googling it....
If you haven't done it yet, pull out the battery, put it back in and try to get into bootloader or recovery. (the pulling out the battery part is important)
by the way, what exactly is happening when you try to boot? please describe step by step what is happening. And what do you mean by boot "into hboot"?
And how did you try to go back to stock? Did you even get into the stock rom. Didn't you just forgot to flash the boot.img when going back to stock?

to flash a rom I
1. Switched off my phone,
2. hold power + vol down (to boot into bootloader recovery), just blank screen no boot.
3. hold power button + vol up, again just blank screen no boot.
4. when us connected led lights up, and PC detects as "unknown device found".
not booting at all.

but did you remove the battery and put it back in or not? If so and it still does not want to go into bootloader, it really is bricked.. Bring it to a service center for repair..

[Q] HELP! I think i hard bricked my S4

Anyone's help would be FANTASTIC!
I downloaded and installed LiquidSmooth 2.6.5 on 06/15/13 wiped everything necessary, went to reboot and it said i wasnt rooted would i like to install SuperSU, i installed it and it rebooted to a black screen and wont go any further. all it does is vibrate every couple of seconds. Is there ANYTHING i can do to get back into TWRP recovery? stock recovery? flash the stock image with Odin? it wont boot into TWRP, or download mode.
Please help, might have bricked my hard earned Verizon S4
Hi,
I've recently just installed the TeamWin Recovery Project.
my Verizon Samsung Galaxy S4 has been rooted, and I even checked with some application on the Google Play market, and it has indicated that it indeed was rooted.
But I still kept on getting the annoying "some application need attention blah blah blah..." in the notification bar, and when I click it it gave me options reboot now or reboot later.
Of course I clicked "reboot now" and after a while, I messed up on my cyananogen mod I guess and I recovered using TWRP through a back up that I have already made prior to flashing the CM 10.1. And it was working normally.
Then I some how went to the TWRP again and it said that my phone wasn't rooted any longer! So I swiped the "root the device now" knob thing and ever since then it has been stuck in the "samsung" screen with the unlocked labeled as "custom" underneath.
Even if I try to do Volume Up + Power + Home button it doesn't send me back to the TWRP screen, rather I see the indication that TWRP has been initiated, but it just crashes and turns my phone off.
When I do Volume down + Power + Home button I can get to the Download mode, but it doesn't seem like my computer can recognize the device.
After the Download page and I push the Volume Up button for the actual download mode on the top left it says
Odin Mode
Product name: SCH-I545
Current Binary: Samsung Official
System Status: Custom
CSB-OEM_Config-LSB: 0x30
Write Protection: Enable"
Click to expand...
Click to collapse
And when I do get to this point my computer does recognize the phone and I know this by hearing the usb connection sound that a computer makes.
How do I get my phone back to factory state so that I can maybe once again trying rooting it again?
Thanks in advance.
and I apologize for so much information even if the rules say that I should be brief as possible, but it felt like the details were needed. (correct me if I'm wrong).

I can't get into the download/odin screen. When I press power + home + volume down it just vibrates.
I don't understand how I could have hard-bricked the phone just by formatting.
Just before rebooting, CWM prompted me "saying root access might be lost" and I hit ignore.

Boot phone into ODIN mode (power off the phone, then press and hold Vol Down + Power then press Vol Up). I think you might have done it wrong.

Thanks DarkMenace. I was able to restore my phone. For some weird reason it refused to go in Odin mode if I didn't have a USB cable plugged in.
I used the stock image, just wondering if I'm still rooted?

If you use a Stock Image you lose root and have to do it gain.

I have the same issue after flashing Liquid-JB-v2.5-OFFICIAL-d2vzw yesterday 6/19/13. Wiped everything, factory reset, hit reboot, it said my device appeared not to be rooted and asked if i would like to install SuperSU. I said yes to install it. When my device rebooted, I got a black screen and my phone won't go any further. It just vibrates, every 2 or 3 seconds. I can get it into download mode. I tried to flash the stock firmware back onto it but when it reboots after, it goes back to black screen and vibrate. Thanks.

Factory Reset?

Reset?
ANyone know how to do a factory reset? I go into Setting under back up and reset and perform the process and the phone just shuts down and nothing appears to happen.
Method 2: I also powered off and the power on holding vol up and home and the screen just goes black. I believe that I am supposed to see the stock recovery, correct? However, I just see black. Anyone else?
ANy Ideas?

Found this is the CF-Auto Root thread posted by another member and it worked:
FYI for everyone wanting to do a reset or something. The recovery is still there, we just can't view it correctly.
The steps to do a reset:
Volume down - 4 times
Power Button
Volume down - 7 times
Power Button
Then wait 30 seconds or so and hit the power button again to reboot.

Lumix DMC-CM1 bootloop; ADB troubles

Hi,
I'm having problems with my great Lumix phone, stuck in a bootloop. I got it in to ADB mode using this a thread: on another site, but cannot get further. Maybe my phone was in MTP before it got stuck in the bootloop. It definitely is running in developer mode. I am on 5.0.2 and the problem started when deinstalling Kingroot via Super Sume Pro
Does anyone know how to solve this problem? Is there a regular factory reset mode, I can't find a keycombination that will start the factory reset other than the one in the thread. If not, does anyone know how to change the mtp to adb mode?
I hope someone out there does know the answer....

Try letting go the power button only when the "lumix logo" appear, and keep holding the volume button.
unfortunately, that does not work either. I noticed that the Lumix logo only apears on the second loop; i.e: first it starts with a screen powerd by Android twice, after the second it goes to Starting system and then Lumix. Maybe that does give you/someone a clue?

I thought that lumix logo is the first thing that shows app.
In that case you need to let go the power button when you see the "powered by android" logo, and keep holding the volume button.
In short, release on the first thing that show up, no matter what it is..lumix logo..android logo..etc

Ok, last thing to suggest is to search google for:
"(your model number) recovery mode"
Or any other suggestions that comes in your mind, i tried doing that but "Lumix phone" didn't come out with anything related because it's not accurate.

Use lg bridge to reset your phone. Not sure if it will relock your bootloader. Anyways you can install twrp again after a reset.

If you still have TWRP installed, here are the instructions for booting to recovery via hardware buttos, aka "button dance". The hardware "button dance" takes good eye/hand coordimation...
1. Make sure phone is completely powered down.
2. Press and hold the Volume down button and the Power button.
3. When the LG logo is displayed release the Power button only then immediately press and hold the Power button again.
4. Release both buttons when the Factory Hard Reset screen displays.
5. Press the power button three times to say yes three different times, like it says. Even though it says it will delete everything, it won't.
6. After a "factory reset processing" appears, you should get the TWRP flash screen.

That's just the bootloader unlock warning. Ignore that.
You'll see that even booting into TWRP.
Keep holding the buttons like the instructions say.
