After trying to flash Pie my G7 stuck in fastboot mode. Download mode is unavailable so I not can reset the stock ROM.
After it reboots it boots into only to fastboot mode and is stuck in a loop now.
An even bigger problem is that now the bootloader is locked and the unlock.bin file can not unlock the bootloader.
ADB mode is not working!
DOWNLOAD mode is not working!
SYSTEM mod does not work!
There is only FASTBOOT mode that is in the loop
Does anyone have any suggestions?

My G710EM has a problem with my lockback BL. I can't boot the system and it will prompt "Your device has failed a routine safety check and will not boot. This may be a temporary problem. If this message occurs repeatedly, visit this link on Another device and refer to the red case:g.co/ABH Your device will power off automatically after a while.” With LGup brush kdz brush does not go in, fastboot “fastboot flash unlock unlock.bin” prompt is invalid

I don't know what to do.
I had the very same problem as OP. I tried to install pie with LGUP (G710EM20b_00_OPEN_EU_OP_0508.kdz) but ended in fastboot loop.
After whole night of trying different things (being a noob means less sleep) I managed to run the phone in download mode. Starting from there I was able to install my previous rom. Both failed update and rescue operations were done on Win 10.
What I tried and didn't work:
- Fastboot --set-active=a
Code:
C:\ADB>Fastboot --set-active=a
Setting current slot to 'a'...

- Unlocking with unlock.bin. Didn't save the msg but saw it somewhere in another thread. I needed to install/point drivers first because the device was not recognized in Win.
- Solutions for G6 for going into download mode. The download mode icon was displayed for a second and then going to fastboot again.
- LG Flash Tool 2014 - I just followed a guide for older phones but it didn't work. Didn't try again.
What did work:
1. I found this post on reddit (remove spaces or PM me, I'm not allowed to post links):

Quoting the post
At first, you'll need a working fastboot environment, you'll find out how to set it up on your own. Then you'll need the laf.img, I can upload mine if you want or I could help you extracting one out of a kdz file. Put the laf.img in the same folder like your fastboot.exe, then hold shift and right click, then click on "open command panel here" or however it's called in English. Type "fastboot flash laf laf.img" (Edit: It would probably better to use "fastboot boot laf.img" instead because of the bootloader lock). If that works, you at least have a working download mode.

2. I used LG_Firmware_Extract_v1.2.6.1 and extracted dz file from aforementioned pie file. The I extracted two laf files for the kz file. In my case they were: laf.img_180534 and laf.img_81990.
3. I took one of these files (sry, don't remember which one, but they have the same size - didn't check if they're the same) renamed it to laf.img and put a folder where fastboot.exe is.
4. I did
Code:
fastboot boot laf.img
and voila: the phone was in download mode!
5. After that LGUP the previous rom and the phone is working again. Here I needed few tries. At first the were some problems, then I tried different combinations (1.14, 1.15, w/ and w/o uppercut). I think LGUP 1.15 (1.14 with patch) did the work. I was able to "refurbish" the phone.
Hope it's useful for others. If anyone could prepare a guide from this description or/and tell why it worked - please feel free to do so.
I think I will wait some time before trying pie again

I recall I also had some error msg, it could've been the same. Now I don't remember what I exactly did next as most my actions were more or less random. Either I tried the same command but with other laf.img file (from the rom I used before), or I tried to restart the phone into download mode (vol- and power together and then vol+ after screen goes black) or tried the same file again.
Hope it helps.

Check if the phone is recognized in LG Bridge. If so, then choose update error recovery from software update tab. Again, I don't remember if it worked immediately or did I need to reinstall drivers and/or choose a proper driver in device manager (generic ADB vs LG...) and/or restart the phone.

Based on other threads, e.g. https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903 and https://www.reddit.com/r/lgg6/comments/axd17d/lg_g6_eu_glh870_bricked_after_update_your_device/
try:
install the LG Bridge updater software on a computer, go to updates, click the "correct update errors" button. Then plug in your turned-off phone while holding down the volume up button. It should switch to download mode and reinstall all software from the PC. Yes, this will erase all data but it should unbrick your phone (unless the hardware's broken I guess)

hi, just one nooby question. where are the adb.exe and the fastboot exe folders?
Hi Mate, It's not noobie at all.
You need to download the Android Debug Bridge (ADB) from this Link :http://developer.android.com/sdk/index.html
Ticket the platform-tools you don't need the rest
Or you can have the easy way and Download it from here: http://forum.xda-developers.com/showthread.php?t=2588979
Or maybe you don't know where are the specific folder in which case go to where you installed it. mine is at C:\Users\Sahar\platform-tools
And on the way download the LG G3 drivers from LG download center or from this link: http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425
thanks amigo! I'll check it out.
@SaharLevi
Here's the fix Quick and easy
need to have fastboot, I used ubuntu can install with sudo apt-get install android-tools-fastboot
info on fastboot
[TOOL] [WINDOWS] ADB, Fastboot and Drivers - 15 seconds ADB Installer
also need recovery.img, I used the lastest twrp
In terminal
fastboot boot recovery.img
this will boot your phone with the img on your computer.
in recovery restore or install a good boot or kernel.
your phone should be good to go after that.
I had my phone fixed in about 5 min, I really should not play around with boot partition.
Also should be able to flash boot if you have a good one,
fastboot flash boot boot.img

if you have fastboot mode you probably already erased the laf partition and you can't erase what you don't have. just continue

i find it
My ZE551ML was rooted and I decided to update it being unaware that I was supposed to unroot it before updating. Once I got to the recovery menu, I attempted to sideload the newest firmware but the device was not found despite being able to be found during the bootloop. I then performed a factory reset and now it is stuck on a bootloop and cannot be detected by adb at any point.
U can use fastboot to flash ur device
But be careful with it u can hard brick ur device if done the wrong way

But how do I fastboot to flash? Every tutorial I found told me to use adb sideload which I never found possible.
Edit:
I solved my problem by copying the firmware I downloaded into an external sd card under the name MOFD_SDUPDATE.zip and going to recovery mode.
download full firmware according to ur device from here https://mega.co.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw give Thanks @shakalaca for this
download (Z00A)2.19.40.18 if u want to unlock ur bootloader cause latest one cause problems with unlocking bootloader
when the device is off press power wait till it vibrates once then immediately press vol up button
u will boot into fastboot mode
there u can use fastboot commands
now form ur pc go to the path where u downloaded the firmware
press & hold shift & right click
select open command window here
now in command prompt give these commands
fastboot flash boot boot.img
fastboot flash fastboot droidboot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
all done ur device will reboot
now u have a rooted device
remember if u want to update than first unroot it reboot than update
where do u get the system.img?
im also in a similar situation where im out of usb debug cause of factory reset

well i manage to do adb sideload even though my phone was wiped completely clean from recovery and still unable to start the android.... it was a miracle . but thanks to your link i know now how to get the system.img
now if i can only understand what system.img is compare to entire firmware zip.....probably i should try to mount one and have a look

System.img is the entire firmware except for boot, droidboot and recovery... These can be flashed separately BUT make sure you use the right commands...
If you get to the usb symbol only displaying on your screen, you've stuffed up and it is a true brick...

I have the same problem than vinod.katakam!
I try to update my Asus Zenfone 2 Laser (ze601kl), to a recente version of Android, because i'm stuck on a older version of Lollipop.
My system had a SKU WW, so i downloaded the recent version WW (marshmallow) from Asus website, and treid to update, and that gives me an error. But i reboot the phone a it works fine. But still on my old android version.
Then i tried to just update to a more recent version of Lollipop, the process appears to start fine, but then it gives me an error. Now, i tried to reboot and i end up with a endless bootloop.
I tried everithing, update by adb (cant open the file), update by sdcard (E:Error in /sideload/package.zip (Status 1) E: fota_return_code 408), and fastboot boot.img, recovery.img, but on system.img says the file is to big.
I dont have de USB Debbugind activated. Is that a problem?
I dont have important data on the phone, i just want to make it work again.
Please help!!!!

if you are on 64 bit windows and fastboot flash system system.img gives you error. probably you are not using 64 bit fastboot tool below is the link to 64 bit tool

Hello guys!
Well, i manage to understand my problem and solv it!
I bought my phone from Gearbest, and the problem begins there. Why? Because, regarless my phone is a CN device, it came somehow with a WW sku. You must know that a CN device have system partition smaller than the WW device.
So, when i tried to updated it with a more recent WW system there was no room for that, and the instalation stops with a error message.
After many "Trial and error", i understand what my problem is, and tried to install a CN system version by "fastboot flash" with a system.img with root that i find here: "https://mega.nz/#F!lodnzDhK!H5ChxausDTyko1qGlnF7dw"
To fastboot i used the fastboot tool that sukhwant717 told me to, in the post #15.
Well, that worked, so i now have a phone working. Them i go to Asus website and downloaded the latest CN firmware to my divece, copy it by USB to the internal memory of my device and upgrade it.
So, now i have a phone working with a factory system but with no google apps.
I found this website with google installer: "https://www.digitbin.com/google-installer-apk/" follow the intructions and finaly i have Google play in my phone!
Now everithing works fine!
I hope that my story could help someone with the same problem!
Hey guys,
I'm trying to root my G4 loaded with MM 6.0. I cannot get into Recovery Mode no matter what I do.
I have tried the key combo (power+down, etc) - it does nothing. If I use adb reboot recovery, I just get the dead Android guy with the exclamation in red triangle. (which is perhaps a hint as to why the key combo doesn't work.)
I followed steps to unlock the phone's bootloader via LG's dev site (success) and I've installed TWRP 3.0.2-0-H815.img but I can't get into Recovery mode. **The phone continues to work fine** and I can get it into Download Mode.
After having no success with TWRP, I thought, f*ck it, since I've gone this far, let's go with CyanogenMod instead of stock, so I installed cm-13.0-20160415-NIGHTLY-h815-recovery.img
I was also able to use adb to push CM 13 (nightly build 20160415) and Gapps (arm64 6.0 20160416) successfully to phone, but it's obviously no use since I can't get to Recovery Mode.
I'm wondering if someone can please suggest a solution or at least a next step.
When I use fastboot flash recovery twrp-3.0.2-0-h815.img it takes 0.718s 'send recovery' and 0.282s 'writing recovery'.
[solved - probably Win10's no-ask driver update policy] New problem: After going back to TWRP, fastboot devices shows nothing and my device is showing up in Device Manager as LGE Mobile USB Composite Device, whereas I specifically changed it from the LG drivers I installed to Android ADB drivers. The device doesn't even list the Android ADB driver as an available option now. WTAF?!? Maybe this is more Win10 driver-auto-update malarkey?
OS = Win10x64
Kernal = 3.10.84
Build number = MRA58K
Software version = V20d-EUR-XX
Developer options are available
USB debug is enabled
OEM unlock is enabled
I'm using the stock USB cable
Additional question - tutorials say to back up NVRAM and IMEI before doing anything risky, but I can't get those without root. How does this make sense?
EDIT: NOTE: You should be using the arm64 version of Gapps on LG G4 H815.
Thank you very much to everyone who stops in to take a look at my questions.
All the best,
Dax.
Hi
I had the same problem with Win 10 not seeing my H815 properly (same device name in Device Mgr as yours) I reverted to the older Lge drivers, 4.0.3 if I remember correctly and the phone showed up properly and I was able to use LG UP to update/downgrade etc.
Like you I have since tried to install TWRP but I cannot new get root with Kingroot 480 although it worked previously on V81520D it does not now.

try fastboot boot recovery twrp-3.0.2-0-h815.img
then tap IMG instead of ZIP (bottom) -> install img and flash the twrp img
Hi Stransky, I reinstalled the adb-setup-1.4.2.exe package which also contains drivers and now ADB will see the phone (which is good), but Fastboot still says waiting for devices (bad). Thanks!
I also changed the default driver from 'LGE Mobile ADB Interface' to 'Android ADB Interface' (as per tutorial instructions).
Hi Bender_007, thanks so much for the tip, I'll try it as soon as I can get Fastboot working again. Cheers!
Okay, so I learned ADB is for Android or Recovery mode, Fastboot is for 'HBOOT' (bootloader) mode.
As expected:
adb devices returns "List of attached devices: LGH81579d3bc56 device".
If I use the command adb reboot-bootloader, phone restarts in bootloader mode.
Then adb devices does nothing, but fastboot devices returns "79d3bc56 fastboot".
When device is in bootloader mode, it shows up in Windows Device Manager as 'Marshall London Bootloader Device'.
Bender_007, the command "fastboot boot recovery twrp-3.0.2-0-h815.img" doesn't work. It's invalid syntax. "fastboot flash recovery twrp-3.0.2-0-h815.img" works as per original post.
Any other suggestions?
Hm, put the twrp inside the same folder where your fastboot and adb are. Then start command prompt in the very same folder and type fastboot boot twrp... And that should be it. That means if everything is normal and the system is bootable.
Pardon, fastboot boot twrp(whatever the name is)
Not: fastboot boot recovery twrp..

Hi Bender_007, that's exactly where the .IMG files are already. No dice. :/
May I see this via teamviewer please ? (teamviewerQS via private message)
I´ll gladly help you (if it´s in my possibilities ofc)

EDIT: 21.04.2016 - we have fixed this, had a nice talk, almost a beer. It´s nice to meet new cool people , keep it up my friend
I am stuck probably on the same issue with win10. It seams like I was able to flash twrp recovery but I can't enter it. Already factory reseted it 3 times while trying to enter into custom recovery.
Any advices what to do?

The best solution there is:
1. put adb, fastboot into a directory (let´s say c:\adb), put the twrp-3......img into the same folder
2. adb reboot bootloader
3. open command prompt, cd c:\adb
4. fastboot boot twrp-3.....img (where twrp-3....img is the actual name of the twrp img)
it will boot to twrp, now you can either copy the twrp img to the phone and flash it(it will ask where to flash - tap on recovery--don´t tap on boot)
You might have to tap on zip/img toggle to enable img flashing first
should you need more help just post in here
Yep that did the trick. thank you! I was able to load recovery with the fastboot boot twrp.. but didnt realize that i can install it by the loaded twrp lol. Now I can finally confirm 2x YES and it gets me into TWRP. thanks again!
Can I make one little tip for everyone else? Follow this guide to the end: http://www.technobuzz.net/unlock-lg-g4-bootloader/
Step 1 is the easiest way to install adb, fastboot and drivers in one go.
Same problem here:
Software version = V20d-EUR-XX, Developer options are available, USB debug is enabled, OEM unlock is enabled
I can boot into recovery via bootloader: fastboot boot twrp-3.0.2-0-h815.img but:
1. had I to allow to modify system partition modifications?
2. how can I boot in recovery from system? with adb I always get the red-triangle Android on its back und with hardwarekeys after shut down the devise, I#m coming to stock recovery: factory restet no/yes
1. Yes
2. While you are in twrp just flash the twrp IMG again via twrp itself. It has the option to flash img instead of zip.

thx, a lot...
Now im running a full system update to exsdcard and afterwards I try to "re-"install the twrp in twrp-applikation.
When i boot into recovery at the moment, the "modify-dialog" is away...
But I will see after "re-"install the twrp how it works...
---------- Post added at 03:48 PM ---------- Previous post was at 03:00 PM ----------
UPDATE:
Did it, worked!!!
on system: "adb reboot recovery" leads to twrp!
there are no hardware-key-solutions to get to recovery...
with the hardware-keys (after shutdown -> power + vol down -> release power for a second when LG-logo pops up) I get to the factory reset no/yes dialog...
On the factory reset choose yes twice. Normal for lg

My G3 had TWRP + CM and I want to flash its stock rom...
For some reason, Download Mode wasn't starting and every time I ended up in fastboot (flashing laf and aboot didn't help either).
So, I decided to erase everything and again clean flash them one by one using fastboot.
Now, here is the problem:
No fastboot command is working! It just hangs at executing the command....
For example, when running 'fastboot erase recovery', it shows
Code:
erasing 'recovery'...
and nothing happens! No response, nothing. The same for flashing, rebooting, ... I have to halt (ctrl+C) every time I enter a command.
The only thing that works is
Code:
fastboot devices
which shows my device with a question mark.
Had the same issue yesterday (after using Fulimics 6.5), my root seemed to be gona, I was stuck in recovery, no backup (what an idiot I am...), can't flash anaything, sideload not working...
I had to come back on stock with the KDZ method : http://forum.xda-developers.com/showthread.php?t=2785089
But you are saying your download mode isn't working ? That's really strange, Volume Up and then insering USB, mainting volume UP until the phone goes into download mode ?

Yes, this all started because download mode wasn't coming up. I press volume up, insert USB and then it goes straight to fastboot:
Code:
[470] Fastboot mode started
[560] - reset -
[560] - partcharge -
[660] fastboot: processing commands
(numbers are different each time)
I think I saw the download mode icon for a second before this but not sure.

What you are trying to do? Just switch from Chinese to Global? or your device is bricked now?
What did happen after that you flashed the Chinese recovery ROM?
What modes do you have available?
Did you unlock bootloader previously?

Fastboot flashing commands won't work if you have bootloader locked.
Did you unlock bootloader previously and probably get locked again?
Did you enable all the proper options on Developer section, i.e. USB debugging and check if device is recogniced on adb commands?
What do you get with "fastboot getvar all"?

And you said you enabled USB debuging?!? you didn't. First enable it under development tools.
MAKE SURE YOUR USING RIGHT ADB/FASTBOOT TOOLS AND DRIVERS.
After 'adb reboot bootloader' use 'fastboot devices'. You can change usb cable and if you still get errors try using usb hub.
If all above fails than try it on WIN7 PC.

I think you are not properly booted to the proper state while you're trying certain commands. Just to be clear; adb works while your device is power on and fastboot commands will work only while your device is in fastboot mode not while on adb mode. A way to be sure that you are doing properly is enabling USB debugging first but while connected device with PC, a prompt will appear from device screen and then tap on "always allow", then you have to type "adb devices" and follow step by step, if device is recognized you can go to the next step with "adb reboot bootloader" then in fastboot you have to see the bunny otherwise is not properly in fastboot mode, then you can follow with "fastboot devices" and so on, keep in mind that any command will work until device is properly recognized.

Just trying to determine what your words exactly mean when you say "after in fastboot mode it doesn't boot in adb mode." ... without entering in more technical insights adb works when device is on, no sense to boot to fastboot to try to boot to adb after that (?)
If you can boot to fastboot what you have to try firstly is unlock bootloader or be sure that is already unlocked using
Code:
fastboot oem device-info
if your device is or get unlocked then you can try to flash or just boot to a custom recovery but if you can't determine until now if your device is really unlocked then you couldn't go further.
The hardware method to enter to fastboot is from a device off; pressing both pwr and vol down buttons but if the bunny is not displayed probably you didn't really get fastboot mode.

Do yo use WIN10? Find PC with Win7... and install adb/fastboot app and drivers. Than try..
Is your system working now?
Just unlock your bootloader and install OrangeFox recovery than you can flash whatever you need.
Problem solved.

TWRP can't bypass encryption, when you have no access to read data (0mb) then you have to format it, to avoid that is always recommended use OrangeFox, just for future reference, if you understand that you can flash OrangeFox through TWRP for better experience.
Also you can use this tool to help you to automate some stuff https://github.com/Szaki/XiaomiADBFastbootTools
