Secure booting Error! - G2 Q&A, Help & Troubleshooting

Hello, about a weekago I've installed dorimanx kernel for my D802 and today I realized that it made my 3g connection unstable
I decided to flash back to the stock kernel which I backed up before flashing dorimanx, but something went wrong. I really don't know what.
The phone won't turn on, it keeps showing LG logo and showing Secure booting error. Cause: boot certification verify. (1001)
I tried pretty much everything in the past 6 hours and i'm losing my mind.
LG PC suite or any LG pc software won't recognize the phone when plugged with USB, and everytime I plug in the phone to my PC windows opens 15 boxes of "new hard drive detected, format needed to use" (here's a picture)
Also tried following this post: http://forum.xda-developers.com/showthread.php?t=2582142, but no luck. It seems like my dev folder is missing alot of sub-folders for some reason.
Anyway I'm really lost. Can you guys please help me to solve this? I would really appreciate it.
Thanks.

To be sure, have you already tried to get into TWRP through the factory reset key combination?

I tried almost every combination possible. the phone simply resets itself to the same situation, screen is on but black and nothing else happens
After holding power+down buttons the LG logo comes up and disappears in a snap, like something is wrong.

Your device is unplugged while you do this right? It has to be completely turned off before doing the combination, and while plugged in, it just doesn't turn off completely.

Yes, it is unplugged while I do it

You'll need to hold the volume down + power key as you turn the phone on, then re-press them when the LG logo shows up to get to the factory reset page. Just verifying the simplest solution before I go in depth with this.
If your phone still won't get into TWRP, try this: plug the phone in to your computer, and open device manager (right click computer > manage) and under portable devices, locate your phone. Once you find it, right click it, click uninstall, and once that's done, unplug your G2 and reboot the PC. Once it boots up, plug your G2 back in and let it reinstall the drivers and try to do the guide again. Best of luck!
EDIT: I just realized the guide you are looking at requires Ubuntu. Are you aware of this?
double edit: http://forum.xda-developers.com/showthread.php?t=2432476
Let me know if you've tried this guide yet.

I believe you're using vistual machine for ubuntu.
Well, if you keep getting 15 messages about formating drives (in windows) when you plug your phone to ubuntu you will not get your patitions in ubuntu.
So you should close the messages asking you to format drives, then open vmware in full screen mode, then plug your phone to computer and follow the guide http://forum.xda-developers.com/showthread.php?t=2582142. I'm sure in this case you will get your phone partitions showing is dev/sdb.
Even if you don't get those partitions keep trying several times untill you succeed.
Good luck.

Thank you!
Apparently I was using the key combination wrong.
And yes I was using ubuntu on a VM.

[Q] I broke my Tf101

Hello everyone This is my first time posting so I hope this is in the correct spot.
I have a Transformer TF101.
I rooted it months ago and can not remember what method I used.
I installed CyanogenMod 10 and everything was fine.
I did an update to one of the nightly builds and now my Transformer is stuck in CWM.
When I plug it into my Windows 7 pc it comes up with a unknown device code 43. I have tried it on several other devices having vista and xp and the same thing happens.
For the heck of it I tried placing the stock FW on the SD card but the transformer does not see it.
I tried placing it in adb mode but the pc still comes up with unknown device.
I have factory reset, wiped cache, and delvik, it is just stuck on CWM.
Can anyone help me with this or did I just totally break the thing? Thank You.
what did you use to flash the rom?
Try doing a cold boot......volume down and power (like you would to boot into recover) but release the keys when the white writting comes up on screen and press nothing.
use v+ and v- to toggle and select the Android or let it kick in itself.
sounds like youve used rom manager

Thank You Scotty: That did get me back so it boots up. None of my computers will see it. Wondering if maybe the cable took a dump. I did use rom Manager. At this point I would like to bring everything back to stock and start over. Any suggestions on how to bring back to stock with sync cable not working?

best just to get the sync cable and use one of the tools available to make sure it gets done right.

[Q] No USB, No Recovery, No Download Mode! Need Advice!

I will try to keep this short but... it wont be. Please don't press that back button!
I had 4.4 on my VZ980 rooted device with a custom ROM but I felt like cleaning it up and starting over (phone was acting up a bit, nothing major) so I went ahead and unrooted it successfully back to factory stock. While unrooted I downloaded the new 12b update... just to check it out. After that lost my attention span within 2 seconds, I decided to flash back to 10b and root again. Everything went perfectly.
After rooting I immediately went and put TWRP on my phone (still stock rooted).. but it would not let me flash 2.6.3.4 only 2.6.3.2... which shouldn't have been a big deal but I.. brilliantly decided NO! I WANT 2.6.3.4... yadda yadda tried a couple different ways, then I read about flashify. Attempted to flashify the file and it still did not work. Within a couple of minutes my phone turned off.... no big deal I thought... WRONG!
My phone is stuck on the LG splash screen. It will not boot into recovery mode... it gets stuck on the factory hard reset saying "factory reset processing" no Teamwin logo ever comes up.. no matter how long I let it sit there
Next move was download mode obviously. But alas, that to bit the big one.. and before you ask I tried every possible button combination.. I was making up my own combinations in desperation. The only things I can bring up are factory hard reset and the hardware key control mode.
Heres the big problem. My phone is not recognized (tried on the factory reset screen and hardward key mode too)... not drivers, not ADB, not even the QHUSB_DLOAD that has been populating the scene lately. I tried downloading everything. Different flash tools, different drivers, different USB cords, different computers, I even tried to use a different OS to see if i could get a reaction.. Nothin! Tried LGNPST, QPST, you name it... I tried it! I even took apart the phone, took out the battery and put it back together (I did this with a previous phone stuck on splash screen and it actually made it work again) still sitting on that ugly splash screen.
Is there any thing I am missing.. that I could possibly try? If not... if it is truly bricked then I need help on how to make it so my provider will not see that it says "Rooted" in the top left corner when they try to put it in factory reset mode.
ANY QUESTIONS/SUGGESTIONS ARE WELCOME! Thank you so much for reading my novela! :good:

It's going on 2 days of trial and error (but believe me I am no expert on this stuff yet, def still learning... the hard way) I do have warranty, but it says rooted in the factory hard reset (when attempting to get to TWRP but it freezes or wont load) so thats another problem!

HEY! I'm on the d801 as well and I've been where you're at a number of times, unfortunately. But I've always gotten out. Here's the conclusion I've reached. Trying to flash directly back to stock without wiping all the partitions first is what makes the RDTool get stuck. It's like the phone runs out of memory and can't host a full Gig+ of data since your last ROM is in the way. Sorry if I'm wrong but I'm only assuming you didn't wipe everything except the Internal storage. The good thing every time this has happened to me is that your recovery partition should be intact. Mine always is, and we're on the same variant. Another thing, booting back into recovery is not impossible. It's all in the timing it takes from the first time you see the LG logo while holding volume - and the power button, but don't let go. What worked for me was to let the phone cycle between off and boot power states twice until the phone is completely off again. You may even notice the LED indicator flash red. Release your keys if the phone stays off and immediately hold the combo down again until the phone tries to boot again just don't let go of the buttons. Once it powers down again, leave the phone alone for a few minutes. Come back and this time get ready to boot into recovery. The combo button press will initiate boot but don't let go until the next time you see the LG logo flash, then quickly release and depress the vol down power up combo and hold. May take a minute longer than usual but the reset menu should pop up thereafter. Tap power 2 more times and you should back into recovery. It's worked every time for me. Let me know if you're good and whether this helped!
Good Luck,

twrp wasnt working after i had restored my back up go straight to fastboot was stuck in fastboot until i found a thread explaining how to get out of fastboot and restore download mode.
managed to get download mode working and tried to flash stock with mobile support tool and got the 49 percent error,
my phone never really displayed any progress just says download mode with a white box and blue dots

K, now if you're only seeing the blue dots when you attach by USB your phone to PC, then you're not fully in DL mode to process the kdz. You should see a white wheel in the center of the screen when you connect and a viewing mirror near the base of your phone with ROOTED in red directly below that. And you're sure your PC is detecting your phone? You've the drivers installed? Because when RDT tells you to run the tool, you'll see some binary code in the viewing window I spoke of, the white wheel will turn and below it will be shown the COM port to which you're connected and a solid thin red bar will begin to fill a space in the viewer showing you the progress.
Also, be sure when attempting the first steps I gave you to boot into recovery that you are not USB connected. It won't work.
And, try to remember if your phone was well enough charged, should have been at least 80% full. It happened to me once that I couldn't boot recovery and my phone would go to fastboot like yours until I left it alone to charge and then I repeated the stepsvi laid out to get back into recovery. This part is paramount!
Please READ CAREFULLY
I used to be in your same situation. I thought I had bricked my phone for good. I finally figured it out. Here is my solution from my Thread.
Esteef said:
Okay, after 12+ hours of trying every method possible on XDA I finally resolved my issue. I will update the first post just incase any others care or fall into the same dilemma I was in.
The LG Mobile Support tool would not download the firmware and it would NOT ask me for my IMEI to download it either.
So my solution....
***
Installed LG Mobile Support Tool then Installed the LG Drivers. (FROM HERE http://forum.xda-developers.com/showthread.php?t=2471370
BEFORE I connected the phone to the computer. I opened the LG Mobile support tool clicked (Options on the top right).
When the dropped down opened, I clicked the (Upgrade Recovery) option. THEN, is when the prompt opened to ask me what my IMEI is.
Before I entered my IMEI, I connected my phone to the computer in download mode, then proceeded to enter my IMEI and hit OK.
This is when the LG Mobile Support tool SUCCESSFULLY downloaded the latest official LG firmware and installed it.
*** BE AWARE, with the phone connected to the PC, the prompt NEVER appeared to enter my IMEI.
*** But with the phone disconnected, the prompt came up every time. This might be the trick for some people.
*** with the IMEI prompt opened, I then connected the phone , entered the IMEI, then hit OK. BOOM HERPES....
Well I'll polish this up more later. I hope this works for every LG G2 Variant and not just the T-Mobile one (D801)

Help, My LG G2 is a mess!

HI
So i was trying to restore my LG G2 D803 phone and I accidentally unplugged it when I was doing the LG Tools process, I turned off my phone so I can reset it but now it doesn't work anymore. So now my phone can't use Firmware Update, and every time I tried to escape it, by hold the power button or anything, it goes back to Firmware Update where its now at 0%. What do I do now?
EDIT: I think the problem i'm facing right now. Is that it keeps going into a glitch download mode when I turn my phone on, and I can't access download mode properly or factory reset, due to going back to the glitched download mode. I tried to flash it properly, letting it drain battery on itself, and turning it off FULLY & turning it back on, where all these methods would just lead back to the glitched download mode.

You can try flashing a kdz for your model in download mode with lg 2014 flash tool. See links below, there might be YouTube tutorials, not sure.

Yea I tried using the Flash tool Way but it doesn't work, I think the problem is that the LG is stuck in download mode so I can't do any Flash tool stuff or anything, and I can't restart my phone because it would just go back.

Can you elaborate more when you say it doesn't work?
After you hit flash on the software, don't do anything for like 25mins. It may show you error messages on computer, that it failed or whatever, pop up windows, don't click on anything just let it stay like that. The progress bar can also be stuck on the phone, not a problem. Give it that 25 mins.

It didn't show any progress on the phone, and also said an error on not working. And there would be no change in the download screen, like it would say that nothing is downloading from the USB port it is in and etc.
But I try to wait for 25 mins and see.

Of the 25 mins or my problem?
I cant do it for now, but I think the problem is that my phone is in a loop of download mode, i mean that everytime I turn off my phone and turn it back on, it goes back to download mode without me pressing the buttons.

You must turn it off completely before booting in download mode. Keep pressing and holding volume down+power for a minute, it should completely turn off after one or two LG logo. If it doesn't then you can unplug battery. After that you don't boot with power button, then you boot with download mode method.
Video from complete shutdown - putting USB in computer while pressing volume up button and starting download mode - software recognizing your device - checking all the correct options in software - hitting flash button - state of phone after flash started.

No, like it automatically goes to download mode wihtout me pressing the buttons, and if i do it the normal button pressing way with the power and volume up, then idk if its the glitch version. But the problem im trying to solve is fixing it so it stops going automatically to the glitched download mode when i turn it on

K firstly, Im not trying to be rude or anything, I just need help fixing my phone. If I somehow offended you in any reason why, im sorry. And I literally don't know much about phones, but I was trying to make sense on your instructions and making sure Im not going to mess it up. If you dont want to help anymore, its fine, im grateful that you tried to help
Also I know how to flash it properly and put it in download mode properly, its just that its always going to a glitched download mode so I can't download anything, or put it in factory mode.

No you shouldn't, rather I am sorry, made a bad judgement call. I left room for confusion in my post. Should've said unplug and plug back the battery. Perhaps you thought if i meant to leave it unplugged.
As your main problem was to stop it from bootlooping into a glitched download, it can be done with holding power and volume down for a minute or two.
But since that didn't work for you i suspected button/hardware failure and so recommended to reconnect the battery.
Another way can be, to let it be as is, so that the battery drains itself and after that charging it with a wall adapter. And see if it stops booting into download itself, or displays a charging only screen.
Anyhow, I hope you find a way out. Feel free to ask anything again.

Nah its ok, that happens to me too sometimes.
So I was going to try to unplug my battery and reconnect it but then but before I was, i was testing some other stuff with the button commands stuff (I mean like the download mode with pressing power and volume up adn stuff) and I think i was able to get the actualy download mode, not the glitched one. I was able to download a bit for the flash tool so what i'm testing rn is to see if I can do the full factory reset and see if that fixes it.
PS: I was already doing the flashtool before so its fine if I erase my data

Sounds like a bootloop, i once fixed it by using another usb port and usb cable. Sometimes they get disconnected for bad connection and cause this kinda error. If MD5 is available, please match yours with original after downloading files. You can keep flashing, maybe try a different kdz later. There is also a TOT method which i never tried myself. This phone is almost impossible to brick permanently.

Sorry for the late reply, just been busy flashing my phone. So I been trying to re flashing my phone using the TOT method because the kda method isn't working, but either 1) it keeps crashing when its downloading 2) cannot recognize the phone to my computer when my phone is in download mode but says its not connected to my computer. Before, it did kinda work, it kept crashing but it lasted a bit longer sometimes, but I had to reflash it because the software update was glitched where it says its on the notification bar but wasnt there. So for rn, i'm still trying to reflash it.
I donno much about the TOT method, haven't tried myself. Getting a hunch that there might be hardware issues somewhere which is interrupting the process and not letting it finish, could be the cable, pc usb outlet, phone's micro usb port....perhaps a loose connection or something else.
If i were you i would stick to the kdz, as it's working somewhat better for you and they all serve same purpose in the end. That youtube video is actually a good step by step tutorial.

HELP! Stuck in Boot Logo w/ no Recovery Mode

Ok so before I started writing this I had only one problem now I'm worried my problem has gone from bad to worse.
I updated my 6T to 10.3.2 from the latest Beta after the process it prompted for a restart, upon restarting it got stuck in the boot animation. I tried going into Recovery and Download mode unsuccessfully so I went through the forums a bit and saw that someone who had the same problem successfully entered Recovery mode by pressing VOLUME UP+DOWN+POWER buttons simultaneously, I tried to do the same and my phone turned off and now it doesn't turn on! :crying:
Has anyone experienced this or know how to fix this? Any help will be much appreciated. Tia!

These should be clarified:
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
Turn the phone off, let it sit. Then try turn it back on. Any response?
try to shutdown phone ...hold vol+ and power button for like 15 sec and restart your phone if this didnt work then u can try MSM tool
Thanks guys, got it working using MSM Tool!

You are likely going to lose your data. Know that going in if its not already backed up.
If you have the fastboot menu you can use the fastboot roms.
Or my least favorite option or what I would try last, MSM Tool (Tmobile 6Ts use a different tool).
IMPORTANT if you want to try and recover and data off your phone first, go to fastboot, and try and "boot" the TWRP img (not the installed one, one from your PC using the fastboot command). If that works you might be able to recover data. If that does worm, try dirty flashing the last ROM you were running and see if it boots.
No worries!

Hello, I am sorry to hear of you having this issue, I just went through 3 1/2 days (off and on) of recovering my T-Mobile OnePlus 6t which I found a way to get my unlock code within 2 weeks of having it, so I rooted it and put a custom kernel on it, stuck on 9.0 never let me update as I was not familiar with A/B partitioning, yet! The answers I saw to your questions were spot on, I just had a little to add to it and I'm sure I am not alone. Real quick let me list what has gone wrong on the rare occasion it hit the fan with the 6t...
- When I would accidentally and rarely let my battery die it seemed like it took forever to get it to reboot, I mean it sat on my desk of DOA devices for 2 weeks!
- It often seems like the buttons do not always respond properly and never have when I needed them to. Been through this before, I've bricked and unbricked and flashed and re-flashed and wiped all weekend and I like Android 10 and all but seems everything is different for every build, and everything seems to have to go in the right order with the exact right file or you wind up in a jam, period..
- That said, the previous person that answered your question has likely encountered similar, I've heard of right down to the buttons not physically working, but I have been a Smart Device Master III Technician for over 5 years, i know my buttons were not broken.
- Most likely culprit that I just handled and worked, i did have to use the MSM tool, several times - and re-unlock the BL, several times I would not even get the chance to get to fastboot, just a screen saying Build and Hardware not a match"" in yellow letters and it just bootlooped. No fastboot is no good, but when you said the tool would show some signs of working but then not, I have 2 solutions that I needed on diffrent occcasions.
1 - As mentioned fully try other USB cables, and ports, if you pull the usb-c out of the port and hold <power + vol up + vol down> eventually it will do something, very picky, sometimes gotta move your fingers to different spots on the buttons and also after 15-20sec let go of power and hit and hold it again... after a few seconds before it vibrates stick the cable in connected to your PC and the screen will be black (obv) but the msm tool will pick up on it. I know about the cables because I take good care of my phones and cables and charging ports, however on my final fix today it showed in msm tool it was connected but waiting for device.... Fed up i put the phone down and moved the usb cable a little bit and it picked up on it and did its thing! That part was just the cable, getting into qualcomm mode or w.e. is a bit tricky sometimes.
- Also someone said set it down for a while and come back to it.. THAT WORKS!! Let it fully charge and often just plugging in charger turns it on, bootloop soft brick or however have you, very simiilar to an Apple device and their DFU (don't f up mode cause screen is black..)
I hope that helps you get in touch with your family and friends.. Whatever you do, don't give up bc if you have not got it yet, you will! One other note, there are a few different msm tools available and they look the same some same size, but the one that supposed to work on my phone didn't and one that they say only a fool would attempt to try actually saved me, so if all else fails, use a different msm tool/usb cable and you will get it! I don't think I can post links yet I am on here very rarely, but plan on more! I have received so much help from XDA throughout the years on thousands of phones with just software issues alone, aas well as guides to my own phones. I would be honored to give back as I also have some extensive knowledge on many devices but I am a noob in comparison to many! Stay safe, good luck and please update and let us/ me know how it worked out for you. If i can help further I will, I have every firmware file for the OP6t, recovery, tools, software, this is not new to me but I feel your frustration!
