Hello,
I have an LG L9 (P769) with 10A software(original) and root.
I have tried installing a recovery by replacing recovery block(/dev/block/mmcblk0p04) with a lg prada recovery image.
Now the phone keeps rebooting at splash1(unanimated LG logo). I have the backup of the original recovery however I would need to access adb or a simular tool.
So far I have tried hard reseting the phone without success, when I connect the phone with my computer it boots to lg splash1 and then keeps rebooting. Everytime it reboots my computer detects a device.
What are my options?
Thank you in advance

After some time messing around and googling emergency download mode for LG phones I found out that for LG L9 to access download mode you need to:
1.) Remove the battery
2.) Plug in the phone to computer
3.) Press and hold volume up and power button
4.) Insert battery
After I got to download mode I basically just downloaded European firmware and flashed it. I used this procedure http://forum.xda-developers.com/showpost.php?p=18946763 both now and before to downgrade from 10e to 10a in order to root using http://forum.xda-developers.com/showthread.php?t=1990705. This worked for me. Someone might find this useful later on :victory:
Hello I bought an LG optimus net (l45c) on ebay, and it was working fine untell It started booting all the time in recovery mode. I managed to flash a diffrent recovery using adb commands, but now it wont boot past the LG logo. I can still get into emergency mode though, and have tried to use KDZ but it just says PHONE NOT FOUND. Is there a way to fix this error? I have discabled the virtual modem, and it didnt seem to help. Is there any way to get into fastboot mode or enter adb commands from here? If I could, I am positive I could fix it.
Thanks
A while ago my phone wanted to do an EMUI update and halfway through it something failed and now my phone is stuck in a bootloop where it gets to the carrier logo screen then restarts and displays Huawei eRecovery (which does not work). I am aware that there are plenty of threads about this issue but none of them have really helped me. My phone was running completely stock software and the default development settings are active (OEM locked etc.) except maybe USB debugging. I've tried to send it back to my carrier but because it has a broken screen they won't take it under any warranty, I have also tried Huawei but their online help is awful and the closest service centre is over 10 hours away. I have no intentions of replacing the screen because for the price of it I may as well just buy a new phone.
As far as the model goes it is a MHA-L09 from Australia (bought via Optus), I have a bootloader code and my IMEI number.
I've tried to access the phone through bootloader and adb. adb doesn't recognise the phone whatsoever but bootloader does (using adb devices and bootloader devices respectively in cmd) but other bootloader commands have no effect as the OEM is locked.
I was just wondering whether I'm able to flash a new rom onto it given the circumstances or whether I should just buy a new phone altogether.

You can use DC-Phoenix to flash firmware.
There are tutorials on how to use it on their website (DC-Unlocker)
Ah, you have bootloader code. Then you might be able to fix this for free.
PM me on telegram, link in my signature
Background: After a night of searching I was unable to find a solution for this. I'm a newbie in the phone tech, but I did root couple of them, back in the days, with stock recovery and with TWRP. The first owner of this phone said it was working well until this happened.
Problem: I got this phone in the state where it's stuck on Nokia logo. Developer mode is not enabled, therefore OEM is not unlocked as well, and I'm only left with a stock recovery with an option to sideload update from ADB, and a Fastboot (Download) mode. I haven't been able to find a trusted firmware and even if I did I don't think it would work without OEM unlock...
Any ideas?
And, oh, I'm using Linux.
Thanks
how do i unlock bootloader on my lg k51
How to Unlock Bootloader of LG Phones Official Method
This is the guide of LG Android Smartphones how to Unlock Bootloader of LG Phones Official Method To Unlock LG G6, LG G7, LG V30, LG V40

I've got my hands on this phone. I've read through all of the replies and I see that @Warlockguitarman has come up with a universal mediaTek method I suppose. So far just going into what I know about LG I've been able to get into fastbootd mode very easily. After that it's a pain in the ass.
You need to download the Minimal Adb and Fastboot tools or just use the latest platform tools. For the people who didn't read the previous posts, the command to reboot to fastboot, is:
Code:
adb reboot fastboot
You'll be rebooted to fastbootd, which is fastboot but moved to the userspace to allow for "flawless" system tweaks.
In fastbootd you can't do much until you've already updated you're drivers from the Device manager. You'll wanna update the LG K500 device I believe. This is the weird part because I can't seem to get consistent results.
Originally I tried using Android Bootloader Interface driver to talk to the device and I noticed that I was getting a HAL issue. Which meant that my cable or driver was messed up. So naturally I tried the LG Adb drivers next. And this time I kept getting (No Link). I then tried searching for some OEM commands. In our devices case, they're hidden by our carriers. So there's not much we can do about that.
On LG's official developer website for unlocking the bootloader, the command to get the OEM unlock code is "fastboot oem device-id". So I tried this as well, and I get a combo of the 2 errors from above. I need more tests from others. If you need help with getting to fastbootd or getting your device to showup in fastboot just ask. We'll help(or at least I will)
On top of everything else, I believe that in order to unlock the bootloader we have to put the device in emergency download mode so that we can dump the full rom of our devices using some low level mediatek interface perhaps. If we can dumb the bootloader, we can extract the hidden OEM commands to see exactly what we need to see. And as @Warlockguitarman says, one of the main issues in getting root is disabling dm-verity. Or boot verification in vbmeta.img.
You can get root without disabling avb, you use patched magisk boot.img and flash in fastbootd, I have my bootrom and preloader dumped and fully understand how the unlock is done, but the correct signature needs to be done to the modified seccfg to be able to flash it to correctly unlock the bootloader and so far only paid tools can do this for the time being... and on the HAL error, that is because fastbootd removes oem commands, so no oem unlock command will work, the seccfg holds the bootloader lock and unlock info an 01 needs to be changed to an 03 and then flashed back. So far only bootrom allows the seccfg.img to be flashed and it requires the correct signature. Check out the mtkclient tool.
