LG G3 D855 Bricked - Broken eMMC? - G3 Q&A, Help & Troubleshooting

Hey guys,
I need your advice/help.
I have googled and searched XDA for 5 hours total now and I couldn't find a solution, so please be lenient if someone has already answered this question.
So I was browing along with my D855 32gb with CM13 on it. Then it crashed, which it did sometimes, so I pulled the battery and restarted. But instead of working flawlessly again like it did so many times it kept on crashing after my restarts (5 at least).
So I went to the twrp recovery, erased cache and dalvik cache and restarted.
It went into a bootloop (stuck at CM logo for hours)
Tried to get to the recovery again, doesn't work, stuck at LG logo. DAMN!
So I tried with download mode, but it starts fastboot mode instead.
So I tried booting twrp in tethered mode with
fastboot boot recovery.img
Stuck at TWRP logo...
I decided to go back to stock completely and try to unbrick it this way, but I need download-mode to flash the tot/kdz.
So I tried the following:
Tried flashing matching laf.img this way:
fastboot flash laf laf.img
Error: [1185970] Error: command never completed
[1185970] Error: Auto CMD12 error
[1185970] Error: command completed with errors
[1185970] Error: command never completed
[1185970] Error: command timeout error
[....]
[1191000] Failed Writing block @1
Tried BOOTING laf.img like suggested elsewhere with
fastboot boot laf.img
Error: (like above) then
"Continuous splash enabled, keeping panel alive."
and stuck there forever
So I tried erasign the laf partition before flashing it..
ends with
"MMC erase failed" error.
A "fastboot oem check_mmc" yields it being stuck there until I unplug it then it says "never completed: too many links"
So my guess is that the MMC broke (since it bricked after erasing cache.. which is very strange in my eyes) and therefore the phone is trash..
Do you guys agree? Can I try something else?
Thank you very much for all the suggestions!

i have a very simillar problem

just fully reinstall your phone if that doesnt work ist broken that simple

And how would you do that with just fastboot, no download mode, no recovery, and flashing/booting laf/recovery not working?

try charging itif it charges (gets to the battery charging screen) you still have a partially working bootloader if not it is a paperweight, try the qcom unbrick tool but with mmc not working it will be impossible

Me to, I have the same problem. Me phone freezed a couple of times, then I tried to reinstall CM and it failed and from then I can't even got to Recovery or Download mode. Only LG logo.

Stuck in boot screen.

As noted Here, and following on, I managed to get updated through to the OTA ICS, and attempted an upgrade to the 3.1 FlexRom.
After some attempts at fixing things, I'm at the point right now, where the issue seems to be in the boot-up sequence.
I have the following variables in play:
* I have fastboot access, but no ADB.
* The tab is now stuck in a continuous loop of the ANDROID boot loader screen.
(previously, it was the FlexRom bootloader)
* The USB at first was trying to install the A500 drivers, and now fails on "MTP USB Device" installation. It fails, but because it's unlocked, I have the first point available.
* CWM no longer loads, nor can I access any recovery functions.
(When CWM was loading, I used it to flash back to the stock OTA rom, rather than attempt another upgrade)
Attempted:
*using fastboot to update the rom via the update command. FAIL.
*using fastboot to run the OEM unlocker. The computer side says "OKAY" but nothing changed on the screen.
*fastboot WILL reboot the tab if given the command, so I know something is getting through, even with the failure of the USB cord to "work"
Have not attempted:
* Hard reset via the little hole. (I honestly don't think it will work)
* Methods I'm not aware of.
So to sum up, I'm stuck in a boot loop and can't get out.
Ideas?
Did you remove bootloader.blob and the recovery folder,from that stock OTA that you flash trough CWM?
I think you are not.That's why you're in this situation.Your bootloader is locked again, and you have the stock recovery (or may be broken recovery).
Try to do hard reset (the real hard reset) with the lock screen button+volume and power (search this forum or google it).It may help you .
Did you try other fastboot commands like: 'fastboot flash recovery recovey.img' or 'fastboot flash boot boot.img' (boot.img and recovery.img must be in the same folder with fastboot to do it this way) what they return?
If above doesn't help you still has a chance with nvflash but you must read this thread after post #48
Hope this is helpful enough!
sending 'recovery' (6144 KB)... FAILED (remote: (00000002))
(for 'fastboot flash recovery recovery.img')
Now it did reboot, and it seems I may be locked again.
This error popped up:
Fastboot: Not support the command in Lock mode
Failed to process command download: hexidecimal error code
No errors on a proper 'hard' reboot, it erased userdata and cache, and is letting me into the setup, so that's probably a good thing.
and indeed it is. I'm back into the OS, and it booted up normally.
I thought I had tried it before, but apparently, it didn't take.
Thanks!

LG G3 Hard Break

Hi there,
I have a problem that my LG will not boot the device is stuck at the logo, I've also done a hardware reset but the process also depends on the logo proof and 10min not happened.
In the download mode, I'm not coming.
About the fastboot mode I try to start TWRP, but it appears the TWRP logo and nothing else happens.
How did you manage to get it to this point? What did you do before it didn't boot anymore?
Also, if you manage to get adb access somehow you can just reflash the recovery again
I ran a SuperSU update and then he appeared dialog that I should restart the system and since I have the problem.
How can I flash the recovery again?
If I want to flash TWRP on the fastboot mode, only the TWRP logo and then nothing happens appears.
So you cant enter download mode or recovery? And you cant turn on phone?
No download mode is not only possible fastboot mode. If I we want to install Recovery in fastboot mode, shown below
Command: fastboot flash recovery recovery .img
Error on LG G3:
Error: Command never completed
Error: Auto CM012 error
Error: Command completed with errors
Error: Command timeout error
Errror:Command completed with errors

Something does not compute in this at all. SuperSU should not have caused your phone to brick like that.
Is there something else you are not telling us about how your phone was set up? Were you doing anything before you updated SuperSU? This looks like a case of where you flashed the wrong image on your phone, if you ask me.
SuperSU is not phone specific, so I'm having a hard time believing SuperSU did this.
Something else must have happened that you are not telling us. You need to lay out in order, everything you did to your phone up to the point of updating SuperSU.
Also, SuperSU asks how to update: normal or via recovery. Which way did you choose? Either one shouldn't matter, but it's a start.
I had the ROM KNVIRUS V11, since I got the message that an update to SuperSU are available. The update I installed then I get the message that the device must be restarted for the update to be finished and since I have the problem.
I wanted to start the download mode just in fastboot mode, unfortunately without success.
command to start the download mode: fastboot boot laf.img

Did you flash the correct laf.img file for your model of phone? If not, that could be part of it. What model of the G3 are you using and where exactly did you obtain the laf.img file from?
SuperSU update should I install because the PlayStore has shown that there is an update.
laf.img I downloaded here: http://forum.xda-developers.com/showthread.php?t=2766437
I found a thread has to ängliches problem: http://forum.xda-developers.com/lg-g3/general/guide-how-to-restore-download-mode-t2897257

Well, there you go. I have NO idea for what version of the G3 that thread was for. The guy never states which version it is. You do not, repeat, do NOT flash anything to system, boot, etc for this phone unless you know for sure it's for YOUR model of the G3. There are various models of the G3. For example, mine is the Verizon model (VZ985). There is an AT&T model (DS855), and numerous others, especially for those overseas. I would not and should not flash the DS855 boot image to my VS985 boot image. It will brick the phone as you have found out the hard way from what I can tell.
You just flashed something you have NO idea which version it was for. You may have completely bricked your phone. I'm not entirely sure, but you need to find the correct stock images for your phone and flash them back.
You need to go here and figure out which model of G3 you have:
http://forum.xda-developers.com/showthread.php?t=2791269
After that, you need to go and find the correct stock image files and flash those back onto your phone. Since this are NOT img files, you cannot fastboot flash them. You muse use either KDZ or TOT files depending on which ones are available for your model of phone:
http://lg-firmware-rom.com/
or
http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/
Then, you have to use the correct tool to flash these files depending on if they are KDZ or TOT file:
http://forum.xda-developers.com/showthread.php?t=2785089
Hopefully, flashing back to the correct stock image will fix you up. However, you better make darned sure which model of phone you have BEFORE you even attempt it. Once you figure out which model of G3 you have, post here and ask. Otherwise, you could bork your phone up even worse to where it may not be recoverable. Hopefully, it's not at that state right now.
I have LG G3 16GB EU version.
As I have written on the first page, I get nothing into download mode so I can not flash it.
What I can not understand why no command in fastboot mode works no matter what I type, I always get the error message: FAILED (remote: flash write failure)

Again, did you verify with the link you posted for the image file that it was indeed for YOUR model of your phone? If not, you probably have bricked it.
You need to go and follow the links I posted which tell you how to flash back to stock.
There was no reason to go into fastboot mode for SuperSU. I don't know why you felt you had to do that.
Also, the second link you posted has the thread pretty much deleted. The OP said he was incorrect in what he posted (whatever it was I don't know since he deleted it), so it was removed due to it not working as stated.
Go back to the links I posted to flash back to stock on your model. If what you say you have is the European model, then this would be the KDZ file you want:
http://storagecow.eu/Xda/LG G3/Stock/Europe Common 16G D85510A_00.kdz
I would verify for sure that is what your phone is before continuing or else, you'll bork your phone up even worse than it is already.
The boot image you flashed is probably for the Korean version of the phone and that's why everything is messed up.
If you are not sure on how to do this, then you might want to find someone near you who does.
Just remember, just because a post says it's for the G3 doesn't mean it's specifically for YOUR model of the G3. You need to verify for sure that it is. Most have the model number in the thread's title.
LG G3 Fastboot

But now i am stuck again on fastboot mode and this time i was not rooted and did not had twrp installed so now when i try to use the "fastboot boot twrp.img " my device will reboot and then will be stuck on twrp logo on the screen
I have the same problem...
I ran stock OTA update 20f, since a couple of weeks ago. While I had my phone on the table and it was runing voice recorder soft it restarted once and then after a couple of minutes again. This time it never booted but stuck at the LG screen.
Never rooted, never installed anything other than the OTA 20e and 20f updates. I have not flashed anything to the phone other than the official OTA.
Doesn't boot to anything other than fastboot. Recovery starts but after confirming twice it reboots and stuck still.
If I boot to Download Mode it goes to fastboot, if I wait long enough on regular boot that only shows the LG logo it will eventually go to fastboot.
Running "fastboot.exe boot openrecovery-twrp-2.8.4.0-d855.img" gives me the same error messages, stuck at the TWRP logo screen. I found the ADB port is connected but when running "adb devices" it says "LGD855..... offline". I didn't enable ADB before the device crashed and I can't enable it in TWRP because it doesn't start properly.
I have the 32GB D855 European unlocked. I belive this is hardware problem and will send it for repairs.

Oeps, `flash write failure` brings back memory`s of the emmc failure with Samsung devices where the sdcard is no longer readable and can not be written on. Send it in for repair, there is no other way and they`ll probably replace the motherboard.

That's right. I tested to boot Philz recovery and it freezes at the text.
Mine says actually:
Error: Command never completed
Error: Auto CMD12 error
Error: Command never completed
Error: Command timeout error
Failed to send stop command
Failed reading block @ 1
mmc read failure misc 2048
The CMD12 is according to emmc spec a "Stop command".
So this is a hardware fault and not a software one.

Android bot error blinking on boot after wipe partition cache process

Model: Asus Zenfone 2 ZE551ML
After updating to latest version i decided to wipe partition cache while on the process it showed erasing android bot then restarted and hung on asus logo for nearly an hour so i decided there is some problem and force switched off then after switching on it shows the blinking android error bot.........im unable to enter neither recovery mode nor fastboot mode(when entering it shows for a some seconds waiting fastboot cmd bt then comes again to the normal boot screen)....
Its been nearly a week i went thru various post and tried most of the methods like entering recovery mode thru adb(as im unable to enter fastboot mode it shows in cmd waiting for device) and pressing both buttons same for stock recovery(it shows some lines saying in last line can't mount recovery)
SO CAN SOMEBODY THROW LIGHT ON WHAT EXACTLY NEEDS TO BE DONE TO RECOVER MY PHONE FROM THIS ERROR.... would be grateful and thanks in advance.
Feel like you for the same worries as I did.
Try to flash bootdroid.img / boot.img / recovery.img with fastboot commands and that should do the trick.
For recovery I renamed twrp.img to recovery.img to get twrp right away

maybe you have flashed wrong droidboot img for fastboot partition.. if you manage to enter fastboot mode, you may try to type
fastboot erase cache
but only if you able to enter fastboot..usually wiping cache from stock recovery may stuck but it can be cleared with that command.. but if you are unable to enter fastboot mode sorry then, hope that someone expert can help you..

Urgent please!!! unable to enter fastboot after wipe partition cache and bot error..

Its been a month my phone sitting quite...

LG G3 Stuck in a Boot Loop. Someone please help me

I think I bricked my G3 :/
I tried usual methods but couldn't get into recovery or download mode, then a few days ago I realized I could get it into this fastboot mode by holding volume up and plugging into USB as you would normally do to get into download mode but you have to hold up for a minute or so (it shows the download mode icon for a few seconds and then goes to fastboot) when in fastboot it connects to the computer and shows in device manager as "android device" and the phone says "processing commands" So I tried to follow this guide http://forum.xda-developers.com/showthread.php?t=2785089 to return it to stock, but I couldn't get it to show up in the LG software.
I read some forum posts about fastboot mode and found that by using the command "fastboot boot twrp.img" (the recovery image I downloaded) in command prompt it would send it to the phone and the phone would display some info and then reboot into TWRP, from here I tried to install a correct rom but the installation starts and there are some errors and then it hangs. I also tried the command "fastboot flash recovery twrp.img" but it fails. This is as far as I have got with it.
It came to me in this condition but the previous owner said he was running Cyanogen and it was working fine until he tried to update it with a nightly build. I suspect he might've tried to install the wrong rom for the phone or the rom was corrupt.
ou could try to revive the phone doing a testpoint and then use boarddiag tools (look in xda thread).
Here is how to make a testpoint: http://forum.xda-developers.com/showpost.php?p=65002893&postcount=17
