[Q] Please help me for unbrick my D802

Hi all,
I am so sad and feel myself as a idiot.
I had D802int version of G2 with rooted and PhilZ Touch recovery which is based on CWM.
Due to not deliveried to my country of KitKat i tried to update my phone with this guide
Everythings were fine. After that i tried to change my TRWP recovery with CWM for external usb storage to restore my nandroid backup and i follow this guide
But I think missed some instruction so my phone stayed in black screen with LG logo (bootlogo - no animation just frozen)
When I try recovery mod it says Secure: Booting error Cause: Boot certification verify on white screen and reset rapidly.
So i check several topics and i applied also download mod and back to stock (kdz uploader method)
For download mod it couldnt jump 2nd step stayed in like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
it couldnt go on 2nd step like this
when i plug usb cable pc didnt recognize as well (no plug-in sound for driver)
Can you help me pls. If I rescue my phone i will quit a long time for this kind of works i think

Secure boot error after reverting to KitKat via TWRP backup

Hey everybody! Please, I need urgent help!
So, yesterday, I upgraded my G2 D802 from rooted stock KitKat to the official European Lollipop, v30b. Before that, I made a TWRP backup of everything.
So, I rooted Lollipop, installed TWRP, and was about to install the new Xposed for Lollipop. Then, **** started freaking out and "LGSmartCover" kept crashing continuously, making it virtually impossible to navigate the UI.
Soooooo, I decided to revert back to KitKat via the TWRP backup.
Everything SEEMED fine, but now I cannot boot. I get the LG logo, then this message appears:
ERROR : boot certification verify
[800]_______________________
[850]
[900] Secure booting Error!
[950] Cause : boot certification verify
[1010]

I do not seem to be able to enter download mode or recovery either.
My computer does recognise it as "qhsusb_bulk" when plugged in, though.
What do? I'll be eternally grateful if somebody can help me solve this.
UPDATE: I somehow managed to get into this "Hardware key control mode" by pressing and holding all three hardware buttons at once, while plugging the phone into the computer.
UPDATE2: Somehow, I managed to boot into Download mode, after doing the same thing over and over again! Trying to recover via LGMobileSupportTool now..

same error
How did you solve it ?

Hi,
I had a similar problem and I managed to repair the phone by using the TOT method with LG FlashTool v1.8 by reaching download mode.
Good luck!

If you can fully enter download mode(first screen and then the second screen),then try to flash a stock rom with LG Flashtool(KDZ method) or TOT method.
Since you were using TWRP,official LG Update tools will kill your phone if you try to flash the stock rom with them.

i have the same problem and i dont know how to reach download mode. when i connect my phome to the pc, it shows the same secure boot error. any help?

Supposing the drivers are installed in windows, you need to have the phone plugged in to comp. and then hold volume-up+power until you get the "download mode" on your phone's screen

leeco le 3 elite x722 stuck in boot loop, please help!

Hello to all who read this.
My phone only shows this two modes but does not get into recovery mode at all, it only shows the first step and then it reboots form the start:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I can't get into TWRP, even if I flash a new recovery with fastboot and run the boot command.
That said I can open fastboot mode and qfil mode.
The problem occurred last night I was watching youtube and in the morning the battery on the phone was fully drained and I couldn't boot into the lineageOS 16 that I'm using (had for 1 month).
The LED light in the top right corner is never lightning up, only when is fully drained then it shows the battery is empty and some blinking red light on the LED.
Well I tried :
- to install/run TWRP it couldn't let me run it
- to qfil the stock ROM and it did let me flash it but it was the same when I pressed the power button after the flashing process
- to use the "update" command in fastboot mode to update the stock ROM on to the phone and it said:
error: update package 'update.zip' has no android-info.txt
Does anyone know how to solve this?
Please help me!
All best,
Jasmin

I had the same issue with X727. Your battery is faulty and needs to be replaced. I got mine from this guy and received an original LeEco battery albeit with 2016 manufacturing date but it works well and phone does not reboot anymore.

Okey, thanks for the replay.

Hi, Jasmin slayer!
Did that Work for you to replace the battery? If not, try to flash some bootloader and verify , If twrp Boots again after flashing. Remember you need twrp 3.3.1 for Andro Pie!

I have the same problem my Le pro 3 x720 device. It is in a boot loop. I wonder if changing the battery will work.

Issues returning to stock

Howdy everyone...
OnePlus 7t Pro McLaren edition (International Edition **NOT T-MOBILE**)
Model: HD1913
Current Software Build: Oxygen OS 10.0.5.HD01AA (OTA update when I first unboxed).
I am having issues trying to return to stock. I rooted the phone with a combination of a couple guides found here (https://forum.xda-developers.com/7t-pro/how-to/10-0-3-patched-boot-image-oneplus-7t-pro-t3986351 and . I noticed after doing that I was missing the stock Oxygen apps and my build information was missing data. Not a huge deal, but I need to wipe the phone and start from scratch anyway, for other reasons. I decided to go back to stock if I have to redo everything anywhere.
First thing I tried, I got the stock firmwares (https://forum.xda-developers.com/7t-pro/how-to/oneplus-7t-pro-repo-oxygen-os-builds-t4003455). And this is where my issues started. My software build is weird... I have the HD1913, however my software build is HD01AA. Per that post, I should have HD01BA. I grabbed both of them for giggles, put them on my storage and booted into TWRP. Tried to flash the HD01AA (since that was what I have now), and it failed. Tried the other one, same issue. I'm getting a bunch of errors while trying to mount the system ("System unable to mount: invalid argument").
Second thing I tried, was to use the built in software update that OnePlus says to use (through the system update). It wouldn't install them (surprise).
Third attempt... Using the MsmDownloadTool (https://forum.xda-developers.com/7t-pro/how-to/op7tpro-unbrick-tool-to-restore-device-t4002909) I downloaded both versions cause I don't know which to use, and followed the instructions to get the phone into the mode. Turn the phone off, hold the vol up button and plug the cable in (very simple). It shows up connected in the software. Exactly 5 seconds later, the phone reboots and boots normally... I repeat this process aprox. 2.3 million more times. It does not matter what USB-C cable I use, the port on my computer, or how long I hold the buttons. The phone will boot into the download mode (or whatever it's called) show up as connected in MsmDownload and then reboot.
The phone works. I am still able to boot it up.... All I want to do is get this phone back to stock. I don't HAVE to, but now that it's fighting me, I have to beat it...

Okay - After sacrificing an iPhone to the Android God, I got it.
Instead of using the button combination to get into EDL Mode, I found an article that gave an adb command (adb reboot edl) to get to it. It did not reboot this time, and I was able to flash HD01BA to it, which matches what the phone should have...

Super Ultra Brick

I tried Unbricking my Oneplus 8 pro using MsmDownloadTool. 4 seconds after Msm run I stopped it, and I got this...

This is caused by download interruption. Recommend you use download tool try again.
You need to confirm if there is failure message on download tool or not when you see this error.
Also please check if you disconnect USB or click stop button when the download is not finished yet.
You can press any key exit this message.

It shows up whenever I try to reboot or go to recovery mode. Nothing works now and USB cannot be recognized except for Fastboot but it didn't help me with booting or flashing anything.
Any Idea?

Did you try to flash a fastboot rom?

Yes I did. It starts flashing well until it requests rebooting into fastboot. Once the phone reboot it goes back to that error message.
