Good Evening,
I mistakenly accepted the OTA update from Verizon yesterday, after putting it off. My phone is rooted, and shows the 'boot certification verify' error when attempting to go into Recovery or boot the phone. Every time I shut my phone off and turn it on I get to the LG Logo with the aforementioned error.
I am not new to flashing, and have searched the forum and found threads on flashing back to the stock ROM and recovery. I have downloaded the *.kdz file, VZW LG Drivers, and the LG Flash Tool. The ONLY thing that is holding me back is getting my phone to boot into download mode. It seems to bypass the method when I press and hold the Volume up (+) button and insert the USB cable. It jumps straight to the LG Logo with the 'boot certification verify' error.
Does anyone have any input? Thank you for your time in read this.

Hi all
As the title states my phone appears to be stuck in a boot loop of sorts.
So I loaded the German V20N via KDZ updater last week and that worked perfectly.
I decided I wanted to use Zeus v2.1 by Huexxx, but I needed a rooted device for this.
So I put the phone into update mode by pressing vol+ and power button.
I then used KDZ updater once again using V10B. This also appeared to update fine.
However when the phone finally booted up I got many many errors of:
"process system root is not responding".
I tried to force close them but to no avail, so I removed the battery.
I powered the phone on yet again and then it shows the LG logo then reboots possibly a few times.
After that it eventually lands up showing the Unlock screen but the touch keys at the bottom are flashing. It will then reboot again and do the same thing.
I tried removing the battery pressing vol+ and power and then plugging it into the USB to get the software update mode. However the phone just turns on instead of showing the update screen.
I have also tried pressing vol- and power. It also just appears to turn the phone on.
Other errors received are:
"The process android.process.acore has stopped unexpectedly. Please try again"
The errors pop up and and eventually the phone will hang and restart before I can actually do anything on it.
The computer doesn't seem to pick up anything when it's plugged into the USB either

I did see that thread, but I was under the impression that because I could not get to the software update mode that it wouldn't work.
As it turns out... You must not press vol+ and power when plugging into usb. Just the vol+ key.
Will let you know if it works via SmartFlashTool.
Thanks
Feel rather silly now...
It seems to be working!
Hopefully I will not screw it up again.
Yesterday I attempted to flash back to stock with ODIN, but after the program said the operation was successfully completed I was left with a problem.
Now, whenever I attempt to turn on the device it hangs at the AT&T logo for about 10 seconds, the screen goes black, and this repeats indefinitely. And whenever I plug the device into any outlet there is the loading screen before it shows how much battery you have, but before it shows the green bar in the battery the screen goes black, and also repeats indefinitely.
I've tried all of the button combinations but cannot seem to get into download mode or even recovery mode.
There was one time where the device booted up, after about an hour of the AT&T logo flashing, but right after the phone booted up it shut down because it died.
Is there anyway I can get into download mode from this state?
You have a late build phone, you flashed Odin one click to 2.1, later builds phones just bootloop with 2.1, and those bootloaders trend to break the button combos.
You'll need a jig to force download mode.
there is a sticky at the top of the dev section with stock packages, I'd suggest grabbing a gingerbread packages with bootloaders, so your phone will boot up AND it'll fix your button combos.
If anyone wants to know, I was able to fix it quite easily, it just took a lot of patience and without a jig.
I first charged the phone for about 4 hours.
Then I turned the device on and let the AT&T logo flash until eventually the device turned on.
Since I was on 2.1 I was able to use the oneclick root application to root my phone. Amazingly it actually went into recovery and I was able to apply the update.zip.
Next I rebooted the phone and waited until it finally turned on again, from here I downloaded a command line application and was able to use that to force the device into download mode.
Finally, I used Heimdall oneclick and my phone was back to normal.
Hello,
After rooting my p880, my phone hangs at boot. Just after the boot sound (*pling* ) the phone is hanging. The boot image is still moving.
Things I tried already:
I followed this thread http://forum.xda-developers.com/showthread.php?t=2069723, which tells to do a kdz update. This is not working, as I am not able to get to the S/W upgrade screen. Instead, when I start the phone using the power button + volume down, i get the Android system recovery menu (3e).
I tried to upload a new (cyanogenmod) rom using adb sideload, but that didn't work, as the file I used was damaged (I will retry with new file).
I also did a factory reset and a cache wipe.
Can someone tell me what is best to do?
Kind regards

you're entering s/w mode wrong. dont press power button. just hold vol down and plug in usb
OOOhhhh noooosss....... That's kind of stupid .
Thanks!
Here's what I did.
1) performed factory data wipe in TWRP
2) Installed all three .zip files, ROM, gapps, and lgapps, all said successful
3) dalvik/cache wipe
4) tried to boot.
When I try to boot my phone, I get the LG splash screen for a split second, then just a black screen. I cannot boot into recovery. I can get it into download mode by holding the power button, then waiting for the screen to go off, and holding volume up and plugging in the usb cable quickly before it goes to the lg splash screen. The problem is once I'm there, it goes to a "firmware update" screen which won't progress no matter how long I wait. My computer also won't correctly detect my phone. If in download mode, it won't detect it at all. If I just boot, it pulls up "local drive" E all the way to R and asks me to format each one. When I try to access E:, it tells me that the parameter is wrong. All the others simply ask to be formatted.
Please help. I probably shouldn't have messed with my phone in the first place. I thought I'd done it right, but I guess not

I might have the solution. You will need Ubuntu/ any other distribution that you want.
Try this, with these files.
Best of luck, hope you can fix this issue!

When you're in download mode, of course it won't progress because it's waiting for you to push an update.
You can use the lg flash tool to. Tot back to 11a from download mode.
However, I had a similar issue as yours and after asking more questions I was able to get back to recovery. The button sequence is tricky when you can't power your phone all the way off, but it can be done. Keep trying or just tot back from download mode.

i was planning on flashing a custom rom on my galaxy s6 today but at work i watched a video on how to get twrp recovery, so i downloaded it on to my phone, followed every direction and step using flashify then when i installed twrp and rebooted my phone it got stuck at the boot load screen, i cant even go to recovery mode nor download mode, everytime i hold the power button and volume rockers it just cuts off and boots back to boot loop cuts off boot loop and so on, idk what to do can someone please help
Slow down, take your time. This is not a permi-brick. Just go back, start at step 1, and try again. There is hope. There must be a way to get into recovery.
I'm having the same exact issue, I'm able to get into download mode by holding volume up, home and power buttons. I'm downloading the stock firmware now and I'm going to try to flash it with odin to see if it works.

If you two can't get into download mode for whatever reason get odin to the point it says waiting for phone or connection or whatever it says then let it boot loop a couple times with the phone plugged in (preferably start from a powered off state). This might just have been lg but for some reason I remember odin rebooting my phone into download mode if the program was at that point.
*edit*
I feel like I wasn't clear enough. You want the tar ball loaded and hit start before you plug the phone in. I could be way off but it's worth a try.
