Hello
I have recently rooted my LG G3 D855 and all went fine until i flashed TWRP, which i most certainly did wrong, and now i have no way of restoring the device since entering recovery presents me with the 2 prompts and afterward a blank screen and flashing red and blue LED. I tried holding VOL+ and plugged in the usb but it does not send me to download mode. Overall the phone does work, i mean it boots up fine and has all it's functions except the 2 mentioned above. I currently an on Lollipop 5.0 V21a. If anyone could guide me on where to look, since the best i have found is restoring back to custom which is not an option, I would appreciate it ALOT.

Hi all, I managed to brick my Optimus G E975 (international version) - the inside of the phone shows E975K.
I have it running the stock ROM for over a year (rooted) and lately I am looking into flashing with custom ROM (KitKat). I have not even flash the phone, I just installed ROM Manager app (pro) and used it to boot to recovery. It won't boot to recover, so I use ROM Manager app to install TWRP (to replace clockmodwork). I booted to recovery and I got the fastboot but could not do anything so I rebooted to normal and install clockmodwork again. There was an option to Flash clockmodwork which I think I chose and I assumed that was installing clockmodwork. But when I booted to recovery, my phone never turned on anymore.
While I got my phone working, using ROM Manager I tried few times to make a back up of the current ROM but it was never succeeded. The phone just rebooted normally.
I opened my phone and disconnect the battery as some people suggested. But I still can't turn on the phone. I got flashing red led when I press the power button (with or without the vol up/down).
Please help. I hope I can unbrick my phone as the warranty is over.
Any info and help would be appreciated. Thank you.
Hey there. I've been using Candy5 for a bit, but kept a nandroid backup of stock. Today I restored stock (was working for a day) but when I tried to restore back my Candy5 nandrood backup from recovery it won't boot, and shows up a LG logo with 'Security error' under it. What may be the problem? I had to go to work and left my phone at home. Will look at it in a few hours,just wondering if you guys saw something similar? Any workarounds to that? Or how to fix it?
Jast flash aosp kernel Furnace od 777jon.
How do I that ? Can't access recovery because it won't boot. From what I've read so far D855 can't go into fastboot.
Have you tried with button combination volume down and power to boot in to recovery? If not then go into download mode with volume up and plug usb cable and reflash to stock rom with Flash Tool.
Didn't even know the combination exists, was used to it from former Sony phones, but it isn't working here.
Yup, reflashing stock now, thanks.
The problem prob was I installed recovery through AutoRec app. That seems to be for 5.0 only.
Which is the best recovery/kernel for 5.1.1?
Furnance and 777jon kernel both are good and work well on 5.1
reboot to recovery with hard keys (hold power+volume down, when see the LG logo, release and hold again keys, then you see the factory reset option, double yes)
flash your current rom again, (no need to GApps again, just rom) wipe cache+dalvik, reboot system.
AutoRec is the problem for me to see this error, and my solve
sorry for bad english
I decided to install Cyanogenmod 12 on my LG G3. Everything went fine until the point of configuring apps and he final reboot. The screen went totally black. I tried rebooting normallly and rebooting into recovery but there was no boot animation or the LED did not even flash. I tried charging the phone but the still doesn't want to boot. I tried to install the stock firmware through download mode by pressing the volume up and plugging the phone into a PC, but I am even unable to go into download mode. If its like the phone's battery is not working but I do not think its battery since it happened at the moment when I installed CM12, unless it was an extreme couincidence. Thank you for your help!
What variant do you have, and what did you install? (D855?) Also try removing the battery and then powering it back up.

So I recently bought the Korean LG G3 (F400) and the first thing I did was rooting it, which was a breeze. Of course to root it I needed to install the LG Mobile Drivers, which I did and were working completely fine. Then I decided to take a little risk and attempt to flash CWM recovery (I did not know that I need to unlock the bootloader first or BUMP! the device) and well, flashed it the same way I flash stuff on my previous Samsung phones.
So now, when I try to boot the phone, I get the LG Logo and goes through with the boot animation, but after a little less than a second the boot animation fails and I get a black screen + the LED flashing blue and green and the phone remains like that. I tried factory reset but after I click yes it shows the LG logo then goes into a black screen (without the boot animation) + LED flashing blue and red.
So I tried finally going into download mode and attempting to return it to stock via LG Flash Tools, and like I said before the drivers were installed, but when I connect the phone to the PC it gives the message "Drivers were not successfully installed" and the LG Flash Tools fails to detect the phone. I checked within Device Manager and it says the LGE MTP device "cannot start".
So I'm pretty much stuck with a phone that doesn't boot, can't flash anything via adb or flash tools and no recovery installed. Can anyone suggest anything I can do to get this beast back up?

So guys
I was on twrp and tried to flash a new rom but when it rebooted after the install, my Zuk z2 died.
It does nothing now. If I press the powerbutton for a long time it shortly vibrates for one second and the notification light also lights up for 1 second, but does not boot up. I tried volume combinations, don't work either.
What can I do guys?
Well, this guy managed to fix it
. Not sure if its the best way to fix it but it's still something

My video. The brick occurs when you usually backup a room with one version of twrp, flash another variant of twrp and then restore the nandroid from before.
Happened to me. Flashed MIUI, and then tried to restore a nandroid (not realising the TWRP changed).
Hope the video helps. Plus then you have a cable premade in case it happens again

Hello. Maybe you can give me some advice. I am stuck in engineering/diagnostics mode after I accidentally selected that option when I was in the bootloader trying to flash TWRP.
Basically, I had installed TWRP and Mokee 7.1.1. I wanted to check out the original chinese ROM so I relocked, flashed with QFIL, etc. I had first flashed MM, then I flashed latest chinese Nougat official.
I didn't like it, so I was trying to unlock the bootloader again, and in the process I ended up selecting the diagnostics/engineering mode. The phone was stuck there and I had no way of accessing the bootloader to reflash with QFIL or MiFlash
TO try to fix, I used the deep flash method you describe in the video, only I found it in zukfans. I was able to open the 9008 port, flash with QFIL/MiFlash. Even though both tools describe the flash as successful, on boot, it goes back to engineering mode.
How to I get out of there? Is my phone done?
Thanks!
