Cannot enter recovery - G2 Q&A, Help & Troubleshooting

Hi everybody.
Today I tried to update my TWRP to version 2.8.5.0 via Flashify (which worked good in the past). But today after rebooting the device I get the error "Secure Booting Error! Cause: boot certification verify" and then the screen goes black. From here i cant do anything but holding down power to boot regularly without any problems. I tried to flash back to 2.8.4.0, but the same error occurs. Any ideas? Should I try Autorec?
I'm on CM12, btw...
Thanks...

Did you flashed the bumped one? If yes, you must use the KK bootloader. This error is because you probably use a JB bootloader.

I don't know if this was the bumped one. I downloaded this one via Flashify. And sorry, I don't know what do you mean by: use the KK bootloader. I'm not very experienced to be honest...

When I google it, it seems that AutoRec installs the KK bootloader, right?

Wrong. Autorec downgrades your kk bootloader to the jb one.

Hi Guys!
I've buy the LG G2 D802 this week!
I've the first problem, I've look for a decent answer, but I've not find it.
I hope you can help me.
- I'm using the Stock Firmware 4.2.2 (10c)
- I've do the root
- I've flashed thrue FreeGee the TWRP 2.6.3.3
- I've Rebooted the phone in Recovery
- I've do a Backup of all Partitions (also the EFS with flashify)
- I've Rebooted the phone
- All is working great.
- I've again rebooted in TWRP
- I've Flashed the ZIP file with TWRP 2.6.3.4
After flashing this recovery, the phone have give me this error:
Checking if loki-ifying is needed/dev/block/platform/msm_sdcc. /by-name/boot needs lokifying
Failed to find function to patch.
Error loki-ifying the boot image.
- I've Rebooted the phone in Recovery, and It's installed correctly the new version 2.6.3.4
- I've Reooted the phone and all is working great.
Now the question is:

I'm thinking...
Is it possible that give me this message because I've the International version of G2 (D802) and it's seems that have unlocked bootloader?
If it has the unlocked bootloader I've read that is not necessary do the loki patch.
This is the only thing that I can think about this error message.
I hope that someone can help me about this question
I don't believe that's the issue even my unlocked Verizon gives me that error when flashing zip files in recovery. It's just a way to bypass LG's security.

Have same error on d802 int 16gb. It install all. Is this normal? After installed Llama Sweet Kernel, use Philz Touch last version.

Boot Certification Error for TWRP?

I cannot figure out for the life of me why I cannot install TWRP on my rooted 4.4.2 ATT D800 LG G2. I'm gonna ask some pretty dumb questions because I feel like I'm missing something here.
I installed TWRP2 custom recovery onto my rooted D800 ATT G2, via the "dd" method using adb on computer. All of the pushing and loki stuff worked, but when I boot into recovery, I get a "Secure boot error" and "Boot certificiation verify" error, then I reboot the phone again and it turns back on like normal. I really want to flash the volume boost onto my device but I cannot without a custom recovery.
I've done hours and hours of research and I cannot figure this out.
Thanks in advance.

Seems like you need to flash the patched kernel for the system to boot.

It installs a boot loader that supports recovery plus recovery plus custom kernel which allows custom recovery and boot loader

I have the same problem on my rooted with IoRoot 4.4.2 D802 LG G2 with Stock ROM D80220c-SEA-xx
But I can't install AutoRec: when the install button is pressed, the installer says "app not installed", and the only option is "done".
P.S. I wanted to ask about it in AutoRec thread but I can't post there because I don't have 10 posts yet.
P.P.S I just downloaded it using another computer and it installed fine!
I have same problem with lg g2 sprint ls980 plz help me ??

Help with AT&T LGG2 .. stuck in mud

Problem: Can't boot into OS on my D800. When booting the screen stays at LG logo and LED keeps flashing green and blue.
Hisotry:
1) Had original AT&T D800 not rooted, no recovery. Got OTA upgrade to Lollipop.
2) Got new phone so decide to debloat to give phone to my wife (on T-mobile)
3) Read xda forums. Downgraded to d80010o using LG flash utility. rooted. installed older version of twrp using autorec. now phone won't boot but can get into download/twrp
4) got into firmware download mode and flashed d80010d using lg flash utility. this time copied new twrp on sdcard and stripped version of rom (http://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195) along with dorilp kernel
5) went back to twrp. flashed stripped rom and kernal.
Still no dice. Exact same situation. I can get into download mode/twrp but when booting system gets stuck on LG logo with led slowly flashing.
what am I doing wrong ?
Are you able to get into recovery? With a lolipo ROM you have to download KitKat boot stack or simply download blastgator lollipop ROM patch from here http://blastagator.ddns.net

From what I read in the OP of that ROM, you're supposed to just flash the rom zip, boot up, go back into recovery and flash the kernel.
"To install ROM, just flash the zip! (Note: The zip isn't signed.) My zip flashes everything you need for the ROM to work correctly.
Recommended: Flash @dorimanx kernel after install. My zip includes stock 30f kernel."
Maybe that's the problem?

okay.. installed the patch. still no dice. still getting same stuck at LG logo with led flashing.
also dorimanx kernal is installed. still getting the issue. btw i am not married to this ROM. Any AT&T rom will work. I think there is some mismatch of bootloader/kernal/rom and what not.
what things I can check ?
pulling my hair out.
whatever rom I install using twrp it gets stuck on LG logo. i think i see some message about not being able to unmount /system (but rest of install succeeds).
only way I can get back in OS is to use LG flash utility and flash d80010d or d80010o which basically wipes away everything (recovery, root etc).
assuming I am on stock d80010d, can someone please give idiot proof step by step direction (do i need to check modem version/baseband/bootloader/radio/recovery versions or something to make sure it is compatible ?)
Do you have download mode?

yes I do ..
Ok flash back via tot to kitkat and take ota to lollipop. Then use autorec v2. *Do not use the twrp thats comes autorec as it does not flash roms* flash a BUMPED twrp using twrp. Then install your lolipop rom then afterwards install the dormainx d800 lollipop patch just for safe measure but it should work without flashing it.

thanks for suggestion.. but once I take LP OTA, how will i use autorec ? I thought LP can't be rooted and custom recovery can't be flashed.
also all I can find is Autorec not autorec v2.

Yeah it can be rooted. Download stumproot and install it, follow it thru the steps and do the brute force root. Takes a few minutes but it works. I've done it on stock a couple of times. Get autorec v2 on playstore.

i just read that stumproot is not supported anymore..
Actually instead of stumproot, use srk tool to root stock lollipop. I have had success with that.

g2 bootloop on lg logo, non working twrp

Hi
I have a d802 lg g2.
Tonight i tried updating twrp via autorec.
after the update was complete i used twrp manager to start a nandroid backup.
After rebooting the phone gets stuck in a boot loop on the LG logo. I can manage to access twrp but the touch is screwed up and the bottom half of the screen dont register correctly so i cant press the buttons needed.
Can I push an older twrp via download mode? if so, how?
Any other options?
Please help

First, I would recommend opening your phone and to check your motherboards model number. There are a lot of refurbished d802's that have altered motherboards. That is why you are facing a broken touch screen and other errors. Please confirm your board number otherwise you may brick your phone.

There's nothing wrong with my touchscreen, it's the updated twrp that don't work properly.

That's not what I'm saying. I think your twrp is drunk because you do not have the correct version installed. Can you check the motherboard model number so that you do not brick your phone.

Situation updated:
last night i updated twrp using cm12, this sent me into a bootloop showing lg logo. i could access twrp but in twrp the touchscreen was acting up making it impossible to do anything.
today ive managed to use lg flash tool with a TOT setting me back to stock 442, after this i used ioroot and i tried installing twrp via autorec and this has put me in an endless boot to twrp and im not able to do anything from there, but touch works in twrp now.
using lg flash tool now fails each time
