[Q] Missing bootloader

Hello all, I've made a bit of a balls up and appear to have deleted the bootloader on my G3 (D855) when I tried to install TWRP. Every time I start the phone or try to get in to the bootloader I end up on the TWRP screen. I have ADB access but I have no idea where to start to recover from this. I think I may installed twrp-2.8.0.0_d855-signed.img instead over the bootloader. Is that even possible?
Any help or advise will be greatly appreciated.
Cheers,
Peter
I do the Same things first time i flash twrp.
Reflash à kdz with flashtool save me.

Actually, its not what I thought. I've managed to get in to the original bootloader. So the question is why is it taking me to TWRP screen all the time?

I've been trying the the last 2 days to sort this out but have come against a stone wall. I've tried on 3 PCs and I cannot get the phone connected via USB (other than with ADB or MTP). To clarify my situation (as my initial post is probably incorrect)....I have manged to "replaced" the Android OS with a TWRP. Every time I start the phone I end up on the TWRP screen. I can boot in to the stock recovery. I have the correct KDZ file and Flash Tool but can't connect to the phone to re-flash.
Please, any help will be greatly appreciated.
What does it say on the PC when you plug it in?
Is it picked up in Device Manager?
Can you get in download mode?
Yep, its picked up as "G3" but with no drivers. I've downloaded and installed the LG unified drivers without any luck. From other pots I think I should be seeing it as "LGE AndroidNet USB Serial Port"?
Download mode? Not sure what you mean.

Now I know what download mode is! And yes, I'm in download mode now. The drivers have loaded!! Going to try a reflash now.
Thank you everybody who helped, the phone is working again! Clearly what I thought I knew does not match what I actually knew!!

[q] lg g3 d855 hard bricked no download mode or recovery!

Hi all, I come to you as my last resort.
I have spent hours on google trying to find a solution to my problem.
This is what happened.
I store my ROMS on an external SD and sometimes i get the error that it is being removed unexpectedly...sometimes..anyway.
I booted into my TWRP and went to flash DarkKnights ROM..this ROM was something like 1.7 GB i think and after completely wiping the device (System, data and cache) i proceeded to flash the new rom..However it flashed very very quickly which i found strange but proceeded to restarting my device.
After that my phone has been completely dead!
What i think happened is that the EXTERNAL SD malfunctioned during the installation and im left with absolutely nothing on my phone.
I cannot enter recovery or download mode!
The only sign of life is when i plug it into my computer and it installs a driver that is the androidnet driver not the qualcom driver that some people have had and fixed.
I am open to any suggestions as you truly are my last resort.
Haven't really got much to say in the way of helping you mate, sounds like you're in a real Pickle :/
I'm sure someone here has a solution, there'd surely be SOME way to resolve it, we've got some pretty talented devs that do some amazing stuff so someone should be able to help ya somewhere.

Try LG mobile support tool (old version) : http://tool.xcdn.gdms.lge.com/client/app/B2CAppSetup.exe
Even if you have not download mode, you can try. Install the tool
Try to boot on download mode, you have error message
run LG mobile support tool
choose Additional functions then Upgrade of the recovery after error
At one moment the tool will say that there is not of g3 connected, reattempts starting in download mode or presses on the button to power. Try several times both.
If it work, the software is going to download the last one kdz available for your device and him(it) to fall in love by following
You can always try this solution, with a little luck ...

Hello my friend..All i did was plug the wire into the computer and then into my phone..and because my battery was very low the screen turned on and showed me the battery low screen..then the led started flashing..and finally the phone switched off completely..Thankfully i have another battery to continue my testing and trying to fix it..but apart from that that happened with the battery im back to square one where my phone is completely dead again and the only response i get is the AndroidNet USB driver being installed on the computer.

Thank you very much for the thread you posted..i tried it but the thing is..my phone has literally nothing on it so when i put each file manually into the phone i dont know which sdb to put it through to..as the thread says it should give a lost of all the system partition files but since my one doesnt have anything on the phone it does not find them...
However, i did manage to establish a connection between the phone and the terminal in linux so im thinking maybe i have to flash each file manually that i can get from a system dump of a g3 and maybe thay will work..what do you think??

Unbrick bricked by writing boot.img to wrong mmcblk

Hello community members,
TL;DR no adb, no fastboot, no flashmode, no QDloader (or similar) ... how to unbrick it?
I was trying to force Android to allow lower lcd backlight brightness levels by patching framework-res.apk and I had the edited zip file ready to flash. Then I realized that my Android 7 Ressurection remix ROM (thread) flashed Cyanogenmod recovery, which I don't like. So I decided to reflash TWRP 3.0.2 (link) ( edit: using "fastboot flash boot twrp.img", which was almost fatal mistake) and it has gone almost well. The phone started to boot into recovery mode everytime (and took a long time doing so). So I googled a bit and found this thread which lead me to this thread. I was looking forward to seeing my display brightness at lower than default values, so I probably skipped some security checks and texts with red color, so I flashed the zip with the boot.img replaced. After flashing I chose reboot and nothing happened since.
The problem is I flashed something that was not for my device (extracted boot.img to wrong mmcblk). The command that bricked my phone is (from META-INF/com/google/android/updater-script):
Code:
package_extract_file("boot.img", "/dev/block/mmcblk0p6");
After that it doesn't boot, doesn't light up LED (even when charging), doesn't get detected by PC in any state.
So I have no adb, no fastboot and no flashmode and not even a QDloader or similar mode.
Is there a way to unbrick it?
EDIT: How to unbrick it using JTAG interface? If I find somebody that has the required equipment, what data do I need to give them?
Hey there! Did you manage to solve the issue, because I just got into the same situation after the zip didn't save the corrected partitions but the initial ones... So i ended up without any signs of life in my phone

Nope, I found no solution ... even some kind of Qualcomm flashing mode via COM (serial port over USB) does not show up nowhere. I gave up and bought a used S5 mini, which is full of features I appreciate.
I'm gonna keep this Xperia M for some time if some solution comes up.

can you still access fastboot mode? anyway you need to know first what is exactly partition that you overwrite with boot.img :/

Help please. Phone is not switching on but is showing blue led light

Hello. I was recently trying to install a custom rom on my Lenovo vibe p1. First I tried to root the device and did is successfully. Then I tried to flash the custom Rom but couldn't do even after several attempts. Then I tried to install my ota update to 6.0 but every time my phone restarted it have an error saying I need to access through fastboot. but then I decided to unroot the device and I also did that successfully. But then an issue happened as my phone turned black. It's not powering on only Blue led light is showing continuously. I've tried pressing the volume keys and power button simultaneously but the phone is not switching on. Then I tried to use qfil tool and whenever I try to connect my phone to the computer it is showing multiple disks (f, g, h, k, j) and it is asking to format it. I'm not able to find my phone in the device manager but all these disks are showing.
Please suggest what can I do. I'll be grateful to you. Thank u

I did have USB debugging enabled but when I started the bootloader unlocking this facility seems to have been removed.
I now have a screen that says 'bootloader is unlocked and OS verification is OFF. Device will continue booting in 30s' The tablet then hangs on the Google logo when it tries to boot up. If I connect the tablet to my mac via USB it goes back to
the 'bootloader is unlocked screen' So I wiped the tablet completely as I was unable to install anything via ADB, thinking I would be able to install via OTG, but the zips are not being detected in TWRP. The tablet also is not being detected when using fastboot. Does anyone have any idea how to get this tablet working again, or is it bricked? Thanks in advance for any guidance that can be given
You can always use the factory images from google.

Thanks for your assistance. Unfortunately I am unable to use ADB and TWRP is not seeing my zips when using OTG, so not sure if it will work. I'll try and put the factory image on my USB and see if it works. Anyone know why TWRP is not seeing the zips on my USB?
I have managed to get OTG working using TWRP and have installed the zip files, but when I reboot I get to the bootloader is unlocked and OS verification is OFF. Device will continue booting in 30s' screen. Is there anyway around this , or am I going to have wipe and relock?

Look at the amount of storge it shows. Mine says zero. It appears we have to put a password in to TWRP for us to see the files before we can zip them.

I have managed to get OTG to work and have installed the zips, but am now getting stuck as per my previous post.

It didn't work in the end. As soon as I connected the tablet to my mac I was getting the same annoying message. I had to RMA it in the end.
