[HELP] Bricked LG G6 US997, Need help - LG G6 Questions and Answers

Hey everyone, I just bricked my LG G6. I was trying to use Uppercut and LGUP to flash a stock firmware, but it wouldn't detect my phone, so i followed this post: https://forum.xda-developers.com/showpost.php?p=70446385&postcount=70
Once I did that and restarted my phone, it got stuck in bootloop and it will display this: "Your device has failed routine safety check and will not boot."
Right now, I can only access fastboot and download mode, but download mode doesn't stick and my PC doesn't detect the phone in download mode, only Fastboot. I can't enter recovery.
Please help guys I don't want my phone to be scrap metal
P.S.: Was running LineageOS prior to bootloop.

Have you tried flashing anything from fastboot?

If you phone has bootloader unlocked then flash twrp via fastboot. If not contact LG for a service

Also wiping misc is a very bad idea

No I have not. Should I? What should I flash thru fastboot?

No I did not. Should I? I bricked my HTC One once doing this and I remember locking bootloader would make things harder to fix for me.

Sometimes getting the phone detected in download mode can be tricky, often you will have to play around with different usb cables and / or computers.
I would try flashing TWRP in fastboot. See if you can get into TWRP, then you can try flashing a rom.

I don't really have lots of USB cables or computers at my disposal though.. Do I just keep trying until it works, and even if so, how do I know when the phone is detected in download mode?
I also found out that even though I can enter fastboot, my bootloader is somehow locked again, and I can't flash the unlock bin so I can't even get a custom recovery to be flashed on there. Any other ideas or is my phone dead for good?

New update:
- I entered fastboot and tried flashing TWRP but bootloader is locked. Tried to flash unlock bin but i get this:
target reported max download size of 536870912 bytes
sending 'unlock' (1 KB)...
OKAY [ 0.039s]
writing 'unlock'...
(bootloader) Error!!
(bootloader) Bootloader Unlock key write fail
FAILED (remote failure)
finished. total time: 0.080s
I'm super desperate at this point. Will LG fix my device if I send it to them? I know warranty is out the window but would they fix it for a payment?

maybe you locked the bootloader at some point with twrp !
maybe your unlock.bin is corrupted you need either unlock bootloader or try to flash kdz via download mode accessing
if you can't do that, LG center is the only way good luck

Why were you originally trying to flash stock firmware?

I realized the visual appeal of custom OSes no longer attract me as much as full usability (Using google pay or fingerprint in some apps) and stability as I used to when I was young. I wanted to flash stock firmware and just keep root and xposed to enhance my stock experience.

Update 2:
I contacted LG and they quoted me a minimum of $300 and up for repairs.. Really hope someone has a fix to my issue or any other suggestions. I'm thinking about taking to a phone repair store but I doubt they will be able to fix this. I live in Houston, TX area if anybody has store suggestions. Thank you

So what rom were you on? And how did you flash it without TWRP? Can you go through from start to finish exactly what you did?

Nexus 10 won't start at all after bootloop problem

Hi,
Just randomly after I ran my battery completely out one time on my nexus 10, I wasn't able to start the nexus 10. The only thing that happened was that it showed me the Google logo, and then the X-symbol. After that, it restarted itself over and over. In other words, it just entered a bootloop. After a while it stopped showing the X-symbol, and only the Google logo. So I wasn't able to start it at all. The only thing I was able to, was to enter the bootloader menu. But from there, I wasn't able to enter recovery mode or something like that, it just entered the bootloop with the Google logo.
When this happened, I had never tried to root it or something like that.
But then I decided I wanted to flash it back to stock with fastboot, to hopefully solve the bootloop issue. Then I followed this guide: nexus10root.com/nexus-10-unroot/how-to-unrootunbrick-nexus-10-factory-firmware/
However, when I tried to write ./fastboot-mac flash bootloader bootloader-XXX.img, I got the following error:
"writing 'bootloader'... FAILED (remote: partition table update fail!)"
Then I read some place that I could try to run several erase-command before I tried the previously mentioned command. After that, I am now not able to enter the bootloader menu any longer. The device will not turn on. The only way to get anything on the screen, is by plugging in the USB-cable and then it shows the loading-symbol. To summarize, I am not able to start my nexus 10 and I am not able to enter the bootloader menu.
Any suggestions for how I can try to solve this issue? Any help will be much appreciated
Update: Now I am able to get into bootloader/fastboot mode again. However, still get this when trying to flash:
sending 'bootloader' (1280 KB)... OKAY
writing 'bootloader'... FAILED (remote: partition table update fail!)
This really drives me crazy. Hope some of you have any suggestions
You have a solution?

Hello find some solution? I have same problem:crying:
---------- Post added at 11:35 AM ---------- Previous post was at 10:44 AM ----------
I had this Problem, when i want to restore to Android 4.4.2 (KOT49H) Factory -> With command "flash-all.bat"
So i tryd to install an older Version, first to Android 4.2.2 (JDQ39) -> That's work! so i had again a working Android.
After i overwrite with newer version 4.4 and finaly overwrite again with 4.4.2. So that way works. (Maybe you dont need to install 4.4 fist, i dont try it.) :good::laugh:

Blasted kingroot - bricked my phone?

Ahh, hind sight is a wonderful thing.
After trying to use kingroot to get root access, it failed. And a few days later after rebooting.
I'm now stuck at bootup with Start Up Failed.
hab check failed for boot
Failed to verify hab image boot
failed to validate boot image
I've now tried lot's of different things, over the last few hours.
RSDLite (show device brings no thing up)
Unlock bootloader (request key, but error regarding OEM unlock not being set - no access to now set it LOL)
Downloaded stock X_Play_UK_Retail_XT1562_LPD23.118-10_CFC.xml.zip, and tried using various guides on fastboot but keep getting remote failed.
I'm on stock recovery (obviously still locked).
Any thoughts, or hope from anyone?
Obviously, not sure what support Motorola would provide for what is essentially my own fault?
Have you tried manually flashing each bit of the stock firmware/image. That might help. There's a good guide here which I followed to unbrick my device. Just follow the instructions http://theunlockr.com/2015/09/22/how-to-unroot-the-motorola-moto-x-play/

I think you need to unlock the bootloader and then start with the 'fastboot oem lock begin' command. You can't flash a system image with a locked bootloader. Let me know how it goes!

I run the unlock command, with my unique key but I get ..

(bootloader) Check 'Allow OEM Unlock' in Developer Options.

And since I can't get into the phone, I can't therefore check the "allow OEM unclock"
Have you tried any erase data commands or reset commands? Perhaps you could reset the phone so kingroot is un-installed and then try to turn on the phone. Short of that I'm stuck for ideas really, accept booting into 'fastboot and then erasing all data and factory reset in there. Let me know.

Have downloaded, and tried that - but the crux appears to be the fact that my bootloader is locked and I can't access the OEM checkbox. And therefore the tool itself can't unlock or equally install TWRP.
Unless I'm missing something in it's usage.

That really does sound like you bricked the device. If you where on lollipop software you wouldn't have the issue with check bootloader OEM unlock. If it was me I would either contact Motorola or go to a repair shop and have a motd experienced person take a look at it.
Try this, not necessary for unlock bootloader

YES you can flash stock Moto roms meant for your model and carrier only.
Also, Never attempt to downgrade.

I edit and made one firmware autoflasher for my x play Indian version and flashed successfully . everybody should check sparsechunk files no in flash file of your extracted stock firmware and edit my autoflasher files according to number of sparsechunk files and flash your firmware. It is definitely safe and I flashed my firmware by this but use at your own risk .
https://mega.nz/#!aoETEL7b!6WUe8tXeh...HHohpfYf2duoLc
First you have to download your phone's correct firmware and extract in fastboot folder , and add my autoflasher and check your sparsechunk files number and make changes according to that in autoflasher then save ..Enter your phone in fastboot mode or in bootloader and not in stock recovery and run autoflasher.
IF YOU HAVE ANY DOUBT AT TAKING RISK , CONTACT Motorola AND MAKE EVERYTHING EASY.

I've ben used the latest rom so far why trying to flash (and failing) when I look at recovery I have a LPD23.118-10 number that matches to an earlier 5.1.1 rom (I had been upgraded to 6.0.1 via OTA updates) - do I therefore take that LPD ID to mean that I should actually use the 5.1.1 rom - I'm in the UK, so I'm assuming I'd use the UK one rather than Europe (I'm looking at roms on https://github.com/motoxplay/stock).
Thanks
Dooh!!
Looking back at what I was doing yesterday, within the mix of downloading various roms - appears that I was actually using the LPD23.118-10 and NOT the latest.
I figured, I'd give it one last whirl using the latest not expecting much - and hey presto, it's worked. Just in the process of resetting it all up again.
Thanks for everyone who contributed, and a lesson learnt about always rechecking what you attempt (and not to try to root if you're not 100% sure of what I'm doing)

Phone Stuck | Need to recover photos from internal memory

Hi All,
Due to in ternal memory full, suddenly my home button stopped working and notifications were not appearing. I tried and followed advice written in one of the websites:
"f you didn't enabled developer settings and usb debug prior to the defect, you can create an icon to call this Activity using Nova Launcher.
After installing it and launching, long press home screen, select widgets, swipe right to find Activity icon, place on empty space in your home, search for setup wizard (it changes accordingly to your native language), select .SetupWizardTestActivity and voilá."
But, now my phone is stuck in SetupWizardTestActivity loop. I desperately need to recover my photos and other data on internal memory.
Please suggest.
Additional Info:
Using Moto X play (updated to Marshmallow)
Bootloader is unlocked
Can't you just boot into safe mode and try if that works.
Boot into Safe Mode
With the phone on, press and hold the power key until the on-screen “Power off” option shows up.
Long press on the on-screen button, and select “Boot into Safe Mode.”
or if you have an unlocked bootloader you can flash TWRP and use the build in file manager to transfer the files to your sd.

If bootloader is unlocked then recovering data is easy, I guess you have TWRP recovery if not flash twrp then pop in a sd-card boot into recovery and copy everything to the card. Done.

is the bootloader unlocked, did you input the code to unlock??just checking
Yes. Bootlader is unlocked with input code to unlock.
I guess adb is not authorised then. when the phone is in setup wizard connect it to pc and type 'adb devices' there will be a pop-up asking you to authorise adb. select it. the try to flash recovery again .

Do you mean to say that I run fastboot boot <enter twrp name> during setup wizard?
Also, alternatively, will flashing a rom without clearing user data help in any way?

adb and fastboot are different things and are unrelated to each other. He doesn't need adb to flash the recovery.

Hi,
I tried re-unlocking the phone using code and got following message:
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
finished. total time: 0.008s
Any workaround?
unlocking bootloader will wipe the data in your phone.
I thought you had unlocked.
what is the problem when you try to setup the phone ? or skip the setup

best option now is flashing the firmware manually without wiping data.
Read this, also read a few comments after it.http://forum.xda-developers.com/showpost.php?p=65715334&postcount=43

Hi,
Where can I find firmware to flash on my phone?
Also RSDLite is not able to detect phone. Can I enter commands from fastboot?
Thanks!

RSD lite needs windows 7.
Yes you have to flash manually then using fastboot commands.
firmware
Just don't use the command to erase user data. Skip it. Open the zip there will be flashfile. xml/servicefile.xml open it , you will find the list of commands to run. Or the commands can be found here.

Just to confirm, will any firmware will work or I need to download one specific to my phone/higher version?
Also, any risks of bricking the device while flashing?

If you are on 6.0.1 then flash 6.0.1...better flash the appropriate region firmware.
There is a risk of bricking if you are downgrading and flash old gpt.bin and bootloader
As long as you are flashing proper firmware it's safe thoughi haven't done it but as you can see the comments I linked previously others have done it.

TWRP on Nougat

I saw where someone said you could flash B20 bootloader and flash TWRP on Nougat, is this true? Is anyone working on a guide for Nougat TWRP and root. On another note I thought that I read that ZTE would be bringing Wifi calling for Nougat with carries such as T-Mobile? I was unable.to find it under options and assume that it is not possible, anyone have any idea about this.
Thanks
I have an unlocked BL and recently upgraded to Nougat, but when I try to reinstall TWRP via fastboot flash method, it fails. I have tried two different versions of TWRP 3.0.3-1 & 3.0.4-1. This is the message I get.
PS C:\adb> fastboot flash recovery twrp-3.0.4-1-a7.img
target reported max download size of 536870912 bytes
sending 'recovery' (14472 KB)...
OKAY [ 0.332s]
writing 'recovery'...
FAILED (remote: unknown command)
finished. total time: 0.363s
Any ideas?

I got TWRP 3.0.4 installed (as well as 3.0.3-1)... It installed sucessfully via Fastboot for me, I even flashed SU, but I couldn't get my phone to boot into the OS (tried with and without SU).......It just hung at the boot pre-boot screen (where it warns you the bootloader is unlocked). I'd restart it, and it always hangs at that screen..... Only way to fix it was to boot back into TWRP, revert back to B29 (using DrakenFX guide) and then update to Nougat again. I spent about 16 hours straight working on this on Tuesday, before I gave up and decided to keep it stock until a custom ROM comes out, soon (Z.A.D. v.4), hopefully?
I have an issue where I installed B15 but whenever I boot my phone, it hangs on the Linux Tux logo. Any fix?

You probably pushed the power button to "Start"? Try letting it sit there about 10-15 seconds, if it won't boot...This is the exact same problem I had. I had to go back to B29, then do the update again. There is now a B15 "return to stock" walk-through, that may be the quicker route.....But I know returning to B29, turning on OEM Unlock in Dev options and then taking the update via your SD card was what I did (3 times in one day).

Those steps are meant to unlock the bootloader.
You don't need any of it. You already have TWRP (skip step 1) and bootloader unlocked (skip step 2) so yeah...
What do you want exactly?

My bootloader is unlocked (back when ZTE actually provided the unlocking)....adb fastboot works on my phone as well and I've flashed TWRP (3.0.4 and 3.0.3-1) and it's booted into TWRP, but I cannot boot into the actual OS...My phone goes all black and just hangs there, I think this may be booting directly into EDL mode and not the OS? I can plug my phone into the computer and my computer makes noises as if a USB device has been attached, but my screen is completely black. If I push the start button while the phone is booting (to bypass the bootloader is unlocked warning screen), I boot to a small penguin screen.
The only thing I can do from there is revert back to stock B29, then update back to stock B15.
I want to be able to install TWRP, root my phone, on Nougat, and be able to use my phone too?

I think I know what happened to you... did you by any chance allow system modifications in TWRP? That makes the OS bootloop if you have Nougat.

The MiFlash program found my phone, but failed every time I ran it.. So, I just bit the bullet and downloaded the latest TWRP 3.0.4-1 and flashed that.....And it worked! I then flashed SU, my fonts and changed my Emoji's....I'm about there with customization, and it's all booting up just fine!
But, yes the first few times I did allow system modifications......But I also did this last time too and it's working fine?

I just asked because the logs show that your LAF partition isn't flashing and from what I've been reading so far about the LAF partition is that it is a very fragile thing.
Have you tried a factory kdz with LGUP?

but after i install the AospExtended, it just play the aex booting video,how many times i erase all date include system and date,cache,etc.
now ,iwant to konw how to get it into a system
Find stock.kdz to flash using LGUP, reflash TWRP using fast boot commands. Should boot correctly after stock .kdz is applied. Once confirmed your phone works correctly.. Boot into TWRP factory reset, and wipe partition, then attempt to flash your choice of custom ROM.
