[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]
[1060]_________________________

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

Nooblet - Need help with my 1+2

Hi,
I bought my phone from Aliexpress. I am very happy with it, but I am facing some issues:
It was pre installed with some diffrent kinds of bloatware.
- Baidu Browser
- DU Battery Saver
- DU Speed Booster
And more see picture -

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
From time to time it tries to download some kinds of files. Seems to be Bloatware aswell. See picture -
In addition to this, the phone also fails to install update: OxygenOS 2.1.1.
I get a message after the reboot, that the install failed, click to reboot.
I've tried to follow this guide "youtube . com/watch?v=-IGDZxeFHAc" with out hope. Most likely something that I am doing wrong.
I have managed to:
Click the RunMe bat file
Install USB drivers
Unlock bootloader
When I try step 4 Flash TWRP Recovery I get to the following message: " Did you see the "okay", then congratulations you have flashed in the recovery "
I did not see the Okay message, and when I press THE any key to quit and boot to recovery, nothing happend its just stuck on Fastboot mode.
Please if anyone could help me I would be very greatful!
Kind regards ..

Download the latest stock firmware from http://forum.xda-developers.com/one...rs-official-oxygen-os-roms-ota-t3209863/page9 and flash that using TWRP. Accessing TWRP after flashing it using fastboot is volume down and power. There flash the stock rom, and it should give you a fresh new OP2

It is still locked or you don't the false, false, false? After oem info it said failed and then try flashing twrp makes no sense
Reflash stock fastboot rom with miflash or use a deep flash cable. And then unlock it correctly
If nothing works you have to open your device and use testpoint method.

really nothing works.
miFlash gives me an error in red.
I already tried with the flash cable qualcomm but the phone when it vibrates it displays the MI logo and is off.
I tried recovery twrp.img but still the same error message

Method MiFlash:
Rom FASTBOOT for Redmi 4 prime: markw_global_images_V8.5.4.0.MBEMIED_20170925.0000.00_6.0_global

Fastboot method won't work as your bootloader is locked. Try with deep flash cable or test point method.
Trying to flash twrp also not gonna work.

I tried the deep flash cable:
click on the + and - button of the volume
plug in the phone and click on the button of the deep flash cable until the phone vibrates ... except that ... when it vibrates it displays the MI logo and ends ... but it is visible on the manager peripheral

Don't use "wipe_all_except_storage".
Use wipe_all only.
