Hi I use a LG G3 and flashed a zip that was not designed for my phone (Validus-shamu-5.0.1.alpha.1.0-TEST-20141217-2151.zip) by a accident and rebooted, and now my phone has a black screen and the led is flashing red and blue (and said error: boot certification verify prior to that stage). How can I fix it?
Additional info: I was using the latest TWRP recovery, and own a d852 variant.
Any input would be appreciated! This is my only phone and I would like to resolve this as soon as I can.
UPDATE: i tried pressing power + up and now nothing reacts, even when i press other buttons. black screen. no LED.
UPDATE2: I removed the battery and put it back in, and now LED are back.
EDIT: FIXED. CLOSE THREAD PLEASE. got my solution from: "What you have to is power + vol down while off till you see the LG logo, then release then immediately press them again it should bring you to a factory reset screen select yes and you will boot into recovery." if people are interested.
I need help as well

Worked for me also! I just exited the factory reset menu and it booted up normally! Thanks for the help!
you're skating on very thin ice if you are flashing anything to your device that is not specifically for that model..

Thank You lazzarusbr!
You Sir saved me a lot of reading
This method helped me get out from the red-blue blinking, black screen Recovery ****up. I believe I got into it because I should have flashed the TWRP using KitKat, but my device came with Lollipop installed....

It means not fully load.
Try to install the AUTORECAR in the Play Store.
Lol. The same thing happened to me on LG-D855. I flashed the TWRP recovery zip and new my phone is literally unusable. It doesn't boot into recovery or into anything else. Sigh.
Hello, please help me. I cant access my recovery mode of my ZENFONE 2. firstly i rooted it using CWM. All went good. But when i tried to open the recovery mode after pressing power +vol up. the recovery mode was opening with Andy opened and lying down and the screen flashing an error. i thought flashing TWRP will be a good idea and it will work. From the PC side everything was good. The pc was showing that TWRP has been flased but when i tried again to open TWRP, by pressing the recovery mode from rectangular box at the top , TWRP didnt open. Even the recovery mode with error is also not opening. when i am selecting the recovery mode the BOOTLOADER is starting again and again . i neither cant access TWRP. i dunno if it has been flashed or not. I can see TWRP nowhere :/. please help me. how do i reach my recovery mode if it is not opening? And what is the problem with TWRP? is it flashed or not?? i dunno. i hope i have made my problem clear to you. Please help ASAP. plz help
same problem here
So, did you guys unlock your bootloader? Bet not...
For me, I'd flash back a stock recovery using fastboot and see if it works...
If you see the android lying on its back with error underneath when you go to recovery, then you need to hold power and press up volume key.
To replace stock recovery with TWRP you need to unlock your bootloader, this is also applicable if you want to flash a custom rom...
I'd suggest you go to general section, look for the stickied threads and do a butt ton of reading before you try doing this again...
Soo.... I messed up and edited the build.prop specificly the ro.build.type property. I tried to enable some debug options without validating if this would be a good idea (hint: it's not).
It seems that this has bricked my phone, the first LG splash screen shows up with the powered by android, and the second animation just keeps loading forever (making the phone very hot). And the LED flashes blue continously.
I did manage to get the device visible in ADB but it tells me that the device is offline so I can't do anything with it.
Tried booting in recovery mode (holding power button + volume down) but it just own't go into recovery mode.
Some extra info of what runs on my phone:
- version H815
- Android 6.0
- bootloader unlocked
- TWRP installed
- Rooted
- XPosed installed
Any idea on what I could try to fix it? (I guess stuck with a brick but oh well).
Thanks!
What do you mean, by it can't go into recovery mode?
Nothing is showing on screen?
Go to downlod mode either use lgup or lg flashtool to reflash the firmware that you are on... Do u remember which firmware you were on ?
Thanks for the replies!

I meant that it just boots 'normally' when I press those buttons, it shows me the first LG logo and the second animation just hangs, whatever I do. I tried all sorts of combinations with the power button + volume down. (Keeping it pressed, briefly letting it go after the lg logo and repressing them).

I don't know exactly which firmware I was on but I can't even get my phone into download mode (same as my other response, pressing volume up doesn't do anything).
The recovery and download mode used to work but I have no idea why it doesn't now...
When booting the phone, hold the power button and volume down button simultaneously, when LG logo appear, push the power button again. You should see the white screen, where you choose "YES" twice. Then the phone should kick you into TWRP or different recovery mode.
But how the hell editing build.prop can mess with recovery and download mode? Sounds incredible

Maybe he has bootloop issue... ILAPO
Yeah I have no idea why the buttons aren't working for me. After a lot of searching I found this thread:
http://forum.xda-developers.com/g4/help/soft-bricked-device-t3248144
Which is basicly the same thing I'm experiencing, ADB comes online for just a brief second (kept spamming the reboot recovery command) and got in TWRP and I just flashed another which worked fine.
Odd thing is, even now my phone works I can't start recovery or download with the hardware buttons...... oh well, thankfully adb works as it's supposed to.
Thank you all for your help!
My dear P2a42 keeps stock on the first boot-logo :crying:
I've already tries to recover boot and system with TWRP 3.0.3 and TWRP 3.0.3-3. Also tried to wipe the whole phone and reinstall the ROM (the modded newest stock ROM), this also didn't work.
Strange problem IMHO... What's the best way to completely reset the phone to stock, flashing it with fastboot?? Or is there a possible other solution?
Thanks in advance :good:
Have a nice day y'all.

Actually in video it's fastboot method only i didn't read the article of yours properly.
Sent from my Lenovo P2 using Tapatalk
Lenovo p2a42 stuck on logo
Lenovo P2 is stuck in a boot loop.
I can't enter the recovery menu. If I press Volume up and power, it tries to start normally. If I press Volume Down and Up and Power, Phone enters "Bootmode is 'recovery'". After 14 seconds, it tries to restart in the normal startup.
If I press power + Volume Down, it enters a menu to swich between "Start", "Barcodes" and "Power Off". it shows dthe device parameters like serial number, storage, ram and the date of the installed software.
What can I do?
The only fix to get back into TWRP,
when the phone reboots, in the short moment of a blank screen you need to press Volume Up + Power.
The only catch is you have to press the Volume Up for a very short time.
It took me many attemps untill i got back into TWRP !!
Do not wipe anything or the phone boots again and you might get stuck in the same shizzle.
So install your favorite Rom & GApps and hopelly all works fine again.
Hi,
I need some help.
So i rooted my D855 G3.
I then flashed the TWRP recovery image on the phone. Now every time i try to boot to recovery mode , my phone shows a "boot certification verify error" in the top left corner and then goes to a black screen with the LED flashing blue and red.
I am able to get back into my regular phone OS , so its not bricked. I have tried several methods of getting into recovery mode (apps, holding power + vol down, adb).
Please can someone help me with this , ive read soo many threads but cannot find a straight answer on how to get passed the error
Thanks
Solved
