Root (GUIDE) Unbrick LG L70 No Download Mode No recovery mode, No Fastboot

D321
When I connect it to the Linux computer, it repeatedly connects and disconnects. The screen stays black and the backlight turns on and off. It doesn't stay connected long enough to run the commands.

fwiw, when connected to the Windows computer the screen stays black and the backlight stays on and I can browse see the image and verinfo folders.

I cannot enter any sort of download or recovery mode; when holding Volume Up it flashes 'Secure Boot Error! cause: boot certification verify'

I never attempted to root this phone or otherwise install any firmware... this just happened one day when I decided to reboot it. :( Is there any way to get it to stay connected while in Linux? Or reflash it while in Windows? I have the driver, kdz and aboot files.

Hello friends !!! I come here to thank the new version of the nightly 13.0 image. Everything went very well in the installation, the phone was great and the rear camera worked very well. My problem started when I was updating the superSU apk via TWRP (the phone asked this since it could not do it by itself). The phone only stays on the home screen, blinking and will not turn on. If I try to connect on the PC I have a BSD (lgandnetmodem64.sys). In no way have access to anything else, the drivers and ADB have been removed and installed dozens of times and absolutely nothing more can be done. If I put it on the computer and connect the device is lgandnetmodem64.sys instantly, I got to format my equipment because I understood the problem was the operating system. Nothing solves. I leave here this testimony so that members do not make this type of update via TWRP under no hypothesis, because my device is unusable. I tried on Linux as well and it does not even appear on the system and I also tried installing ADB, but it was live cd and it is not allowed to download packages for this procedure. Thank you for your attention. Best of luck to you. My device is lG L70 325f.

I came across the D320N which is bricked - purple screen. There is no way I could do the trick with the linux. I did all the steps from the OP but it just dont want to go into download mode afterwards!
Is there any other way of doing this? I have downloaded original KDZ file, and file in it is just 1 MB and the other ones in repository are 2 MB.
Is it possible to create Loader.img like for the L80 and flash it with the win32diskimager, and how?

I have a page that supports the Brazilian variant, I tried to help people in any way, using boardiag, qfil, but none worked, they even install the rom in the device, but still it remains erased or on the purple screen. We can try to use loader.img, but I do not know how to create it. Do you know?

Hello,plase help me with my LG D321.I nead LOADER image to unbrick my cell phone micro SD
You can make it folow this steps
1) Take a fully working mobile phone (with the Root, and the program Terminal Emulator and BusyBox)
2) Start the Terminal Emulator and enter the command:
su
dd if=/dev/block/mmcblk0 of=/sdcard/Loader.img bs=1024 count=168960
At the root of the internal memory of the phone will create the boot image file.)
This is what i did in the working L70 and i got Loader.img but it is 168 MB and the partition on the phone is only 63.9 MB.
So I could'nt dare to do the flashing with 32diskimager. This is how phone disk partitions looks like in Windows.

I have just tried with the SD Card and no go! It just does nothing! Although, the created SD Card had the same files as in the phone. So my next question is what can I do with the partitions in the device format them maybe and how?
Also just tried flashing Loader.img with the win32diskimage and it just quits after it begins with the error. Still in purple mode... :-{

When I try to do this I have this problem. My biggest number is /dev/sdb5 so I use sudo gdisk -l /dev/sdb. Problem is it only detects Linux filesystem and Linux swap. I don't have many lines with aboot like you do. Is there something I did wrong? I'm using Linux Mint installed on HDD, not VM.
Click on the upper right corner to select the drive - L70 and then post screenshot.
