FIX BRICKED LG G3 (LS990) "Stuck In FastBoot". "LG Security Error". "Factory Reset 2"
Hello Im posting my solution to how I had fixed my bricked LG G3 LS990. I bricked it a few days ago and searched tons of forums and youtube videos and it was tough trying to find a solution for this variant of the LG G3. And I had seen that everyone who was having the same problems I had couldnt find the solution either, but luckily somehow I had figured it out...I even took my phone to the Sprint store after my phone was getting "Security Error" and they couldnt even fix it and had to ship me a new one in which I no longer need since I fixed it myself...
My phone had went through these 3 phases in this order, so I also have the instructions in same order ( Be Sure To Follow All Directions Closely)
-Stuck In Fastboot
-LG Security Error
-Factory Reset 2
SINCE THE LG G3 LS990 PHONE IS THE ONLY ONE IVE TRIED IT ON THEN IM ASSUMING ITLL ONLY WORK FOR THIS VARIANT, BUT I HAVE SEEN MANY FORUM POSTS WHERE ONE METHOD WORKS FOR MANY LG G3 VARIANTS.. JUST BE SURE YOU HAVE THE CORRECT FILES FOR YOUR LG G3 VERSION

Hello and thank you for posting this info. My situation is a bit unique. I have a Sprint LG G3 that is rooted and has been running various ROM's. I want to go back to stock/unrooted and have followed the instructions in this thread (http://forum.xda-developers.com/sprint-lg-g3/general/guide-how-to-restore-sprint-lg-g3-ls990-t2852042/post60463455#post60463455) using the LG Flash Tool to attempt to flash the TOT and DLL files for my device. But for the life of me I can't get it to work.
In the thread above I wrote a short post explaining what I think the problem is, but bottom line it gives me an error when I try to flash the files. So then I found this thread and thought this is great, I'll just grab the stock image files for the Sprint LG G3 ZV4 and simply flash them via Fastboot. Alas, when I try to do it with the phone off, or in Download or TWRP recovery mode ADB and Fastboot do not see/recognize the phone. If I have the phone booted up and plug it in, it will list the device (although it says offline next to it, so not sure why that is), but when I put the phone in recovery or download mode ADB/Fastboot Devices command will not list the device to show it is recognized. I assume the phone can't be booted up in order to erase and flash the various partitions. I have debugging mode turned on, the LG drivers installed, etc., what am I doing wrong here? Why doesn't the PC see the phone when it's in download or recovery, but only see's it when it's booted up.
All I want to do is return this phone to stock/unrooted ZV4. Please help.
Thanks

Sorry for the late response, I guess I dont get notifications..but I think I had the same issue, but as long as the cpu sees the phone once its booted up you should be able to flash the files from Step 1 using the command window on your cpu
@Celly624
I have a few questions.
When you where stuck in fastboot mode, did you try to pull battery and boot into recovery?
Which aboot version where using?
I've been in fastboot mode several times, and security error. For me it's a bad boot.img, ie not booting kernel or forgot to bump img. For me, pulling battery and going into recovery and flashing good kernel fixes issue. Also done the fastboot command to flash kernel/boot.img. But don't always have a computer around.
este fue mi problema FACTORY RESET STATUS 2

Thanks for unbricking my phone from the mess that the supposed Auto-Rec TWRP installer created.
For those who get the "Factory Reset Status 2" message, you need to close out LG Flash Tool, unplug the cable, pull the battery, push and hold the up arrow while plugging in the cable, restart the LG Flash Tool, go back to manual mode, and change the bottom setting from "Upgrade DL" to "Board DL", then resume at Step 29.
If you then get a MiniOS ATT screen with the "Don't touch!" message, just press OK. Now pull the battery, reinsert the battery, press and HOLD the power button. While continuing to hold the power button, wait for the MiniOS screen to go to the multi-option menu. Choose "Normal boot (+power)". It may take up to 15 seconds for the popup message to reboot your phone, so be patient. Choose to reboot it, and you're now back at stock.
If doing the above still keeps you at the MiniOS options screen, press the power button and choose "Factory Reset(+power).

I kept hanging at 89% FBoot Check Failed. This time I did what you said during the FBoot check: I held the power button through the MiniOS screen and hitting OK on the screen check. I waited 5 seconds, then HELD the power button down again while hit the "Normal boot (+power)", which rebooted the phone into the expected Android is Upgrading screen. Note that I used the LS990ZV8_00.zip, which has the ZV8 tot inside and the LGUP_8974.dll in the LG Flash Tool with the Action Mode set to Board DL.
Currently running Sprint original ZV8 for ls990 v5.0.1. Accepting over the air upgrade. Now gotta figure how to root....:laugh::silly:
Hello I bricked my g3 and I have only access to fastboot but when I try to erase or flash some partition I got these error message:
Code:
Error: Command never completed
Error: Auto CMD12 error
Error: Command completed with errors
Error: Command never completed
Error: Command timeout error
Error: Command completed with errors
Failed to send stop command
Failed writing block @ 1
I could access to a adb shell booting with a twrp image (fastboot boot twrp.img). Then I try to push a twrp recovery file and execute dd commands to copy recovery partition files but I think that I don't have access neither.
Thanks for your help
Any idea how to do this for G3 D855 European version?
I had this problem once because of misinformation on downgrading to ZV4. They failed to mentioned BOARD DL instead of UPGRADE DL. It was a simple fix by recreating the steps and switching the radio buttons.
gets tuck when trying to erase aboot
i rooted my phone and erased apps now i cant access google services and most app force close. im trying to flash back to stock firmware and i cant access download mode. ive been trying to fix this for the passed 2 months now and ready to smash the stupid thing lol.
HALP
Hey, everyone. So, I made a pretty similar mistake. I've had my phone rooted for a while, and, while trying to test a custom ROM (Cloudy G3, in case you were wondering) I managed to mistakenly flash the D855 version onto my LS990 phone. Of course, I was stuck in Fastboot for a while, but now the phone only lets me into download mode. I've tried entering Recovery mode, but that just takes me right back to download mode.
That being said, the LG Flash Tool recommended isn't doing squat. If I attempt to flash the stock LS990 DLL and TOT, I get an error telling me that my phone is the wrong version, as the last software flashed to it was, indeed, the D855 firmware. If I try to flash the D855 DLL and TOT, it gets to about 6%, where I get an error about partition change.
Considering that I may not have the right drivers, I reinstalled the LG drivers as well as Qualcomm drivers to be safe. However, my computer still doesn't register my phone as anything but "LGE AndroidNet USB Serial Port," which isn't what it should read, if memory serves me correctly.
I have no idea what to do, and I really do love this phone... Can anyone help? Please?
unable to download fastboot files please help( error; requested file does not exist )

- FACTORY RESET STATUS 2
I followed these suggestion & it worked on my LS990 (Sprint G3) : On LG FlashTool I switched to Board DL instead of Upgrade DL
Your phone will reboot to the AAT Screen – Click OK (Yes, it says not to), then press normal boot (+power).
Your phone will reboot and all should be well.
It seems to have helped a few people get past that screen :laugh:
Hopefully This Should Help Just About Everyone Having These Problems! :angel:

link provided doesn't work.

Hello, first post and fisrst tutorial here.
So here I want to show you how you can restore completely died LG p760(or his brothers p765/p768/p769) showing nothing or just LG Logo and so well known "Security Error", or boot loop problems.
The goal is to flash stock recovery, x-loader and u-boot and to unlock the bootloader(u-boot), so it can boot Clockworkmod or TWRP recovery.
First of all you'll need a computer(preferably Win7/8), an died phone , some drivers on the computer and fastboot on the phone. Let's start.
I'm not responsible for any damage to your device made during this guide. You can continue at YOUR OWN RISK.
Please READ IT before taking any actions on your phone!
1. Get fastboot on the phone. How? You can see here and here, or search the internet. There is a driver package, install them following the instructions.
2. After you inserted phone, installed drivers, etc. start the fastboot loader script(I prefer Lelus's one, i'ts more option-rich), and select one option for ICS x-loader and u-boot for your phone. Follow the instructions, it may take 2 or 3 tries before the drivers are correctly installed. Start again if the drivers are not correctly installed.
3. Copy the bin folder that is inside the fastboot files folder in C:, press winkey+R, type cmd and press OK.
Then copy everything from v20c_00 folder inside the C:\bin\ folder, it's in attachments in the end.
Here is the time to say that this files are for p760 only, you can find x-loader, u-boot and stock recovery for you model from internet, or here in the forums. I flashed also the boot.img, but don't think it's necessary for the completion of the process. You can also extract the .img files from stock .KDZ rom with this tool here, thanks to user kuma82. In the archive is the tutorial how to make x-loader.img, it's easy.
Let's continue.
Type in:
Code:
cd C:\bin
Check if the phone is in fastboot mode with this command:
Code:
fastboot devices
It must show something like:
Code:
1234567890 fastboot
If not, check that you are in the correct folder(C:\bin\), go and check drivers(no yellow marks or unknown devices), read the instructions again.
Then after you copied the files from archive, or files that you extracted from your stock rom, type in, or copy and paste into the cmd window:
Code:
fastboot erase x-loader
fastboot erase u-boot
fastboot erase boot
fastboot erase recovery
fastboot flash x-loader 0-x-loader.img
fastboot flash u-boot 1-u-boot.img
fastboot flash boot 2-boot.img
fastboot flash recovery 3-recovery.img
You must be fast, because after 30-60 seconds(don't know exactly) of inactivity, the phone will exit the service mode it is in and try to boot. Nothing bad happened, just load fastboot again and repeat the above fastboot commands.
After all the commands are completed without any errors, plug out usb, plug out battery, put the battery in, start the phone. The "Security Error" message MUST be gone. If it's not, probably your recovery is wrong, flash recovery again, if not, try with other recovery. This is working on P760, at least on mine. Here the S/W Update mode must also work like a charm, and you can try with some KDZ updaters, but that's not for this tutorial.
4. Now for step 4 we will need the phone in Recovery Mode. With phone turned off and battery inserted, press VOL_UP+HOME+POWER, when LG logo shows, release POWER and hold other two while the LG Recovery Mode show up. The phone must go straight into recovery, not bootlooping or showing "Security Error". If this happens, probably you recovery or u-boot is wrong.
Now put the usb into the phone and install the drivers from usb_drv_windows folder that is in the fastboot archive.
5. Type into cmd window:
Code:
adb devices
It must show something like:
Code:
1234567890 recovery
If not, you know..
Then we will unlock the bootloader with this command:
Code:
adb oem-unlock
The phone will restart, don't touch nothing. You'll see screen with info on what to do. Guess what..? We must press the VOL_UP button to confirm that we want to UNLOCK the bootloader, so it can load unsigned recoveries like CWM or TWRP and not to show the annoying "Security Error".
6. The phone will go into fastboot mode itself, you must install the drivers, again from the folder in the archive.
Now we'll flash CWM recovery with the help of fastboot. Copy the recovery-clockwork-6.0.2.9-p760 or recovery that is for your model to C:\bin\ folder.
Write:
Code:
fastboot flash recovery recovery-clockwork-6.0.2.9-p760.img
fastboot reboot
The phone will reboot, and hopefully you will not see "Security Error" error message. Now try to boot into recovery - pull the battery out, the usb cable, put battery in, and hold down VOL_UP+HOME+POWER, you know..
7. If everything is successfull you phone will load the recovery and you will be able to load nandroid backup or stock update.zip or CyanogenMod on your phone. Don't forget to wipe cache/data and dalvik's cache. From here you can backup your data or do whatever you want.
If your phone is not totally bricked, and if you are lucky enough you can continue from step 4(if you have recovery in your phone and it's still loading).

I want to attach them here to the forum, but I can't for now, so here is Google Drive folder.

Hello guys,
i have a bricked rooted oneplus x
I had issues with the rooted rom so i flashed the newest stock rom via twrp
The phone boots up and showed the usual otimizing apps message. After the proccess is done it just the usual "let me helpt set up your phone page" and then restarts
I cant acces twrp anymore and when i try to acces the stock recovery it just shows a oneplus logo
I do have access to fastboot though (i hope that leaves some hope)
I have tried the MegaUnbrickGuide here in the forum but i wasn't able to install the drivers i need for that method
One more thing whenever i try
Code:
fastboot boot recovery.img
i get the "remote dtb not found" message
Does that have to do with developer options not being unlocked?
Any ideas on how to just get some form of working os installed on the device
(i dont care wheter rooted or not at this point have been trying stuff for hours now)
regards
Jan
First download Minimal ADB and Fastboot and install it.
Go into fastboot mode.
1. Re-unlock your bootloader using the command - fastboot oem unlock
2. After doing that, download the latest version of TWRP(which at the time of writing this is 3.1.0) and rename it to 'recovery.img'
3. Open a command window in the place you have downloaded the recovery by pressing the shift key and right clicking and then choosing the option Open Command WIndow Here... Flash the recovery using the command fastboot flash recovery recovery.img
4. Boot into it using the command fastboot boot recovery.img
5. If it still gives 'remote dtb not found' then follow this guide: https://forum.xda-developers.com/oneplus-x/help/opx-remote-dtb-solution-t3480274
6. If it boots into recovery, your phone is now fine and go ahead and flash whatever ROM you want.
Cheers!
Hi guys,
So I rooted my swift 2x but now I want to unroot it so I can use baking apps. Trouble is I'm having difficulty unrooting.
My method for root was
> Unlock bootloader
> Install TWRP
> Install Supersu
But now I can't unroot. I've tried unrooting via the supersu app but on one try it errored out and nothing changed and on another try when the phone rebooted it got stuck on the white wileyfox screen.
I've also tried to install the reocer image from here https://forum.xda-developers.com/swift-2/how-to/marmite-android-7-1-1-tos118c-fastboot-t3605101 via twrp but then once I reboot after installation from TWRP it gets stuck on the white wileyfox screen after seeing messages that the device is corrupt on a previous screen.
What can I do to unroot?
Thanks!
Return to stock via fastboot... it will fix everything. I had to leave LineageOS because nothing I tried would allow me to use my Banking app now they've really tightened security, thanks to Google's CTS. Shame.
(LOL on the "baking app")
EDIT: This Thread has all the files except the latest. Flash TOS319I and let the phone OTA to TOS373J.
Since you have already done this I thought maybe you might be able to help me with an issue I am having
From your thread I have used the first part of the following thread https://forum.xda-developers.com/showpost.php?p=72827221&postcount=7 - to fastboot "Android_7.1.2_Wileyfox_Swift2_2017_09_07 TOS249H - Signed Fastboot" -
Everything went as it should have (or so it appeared) but when I went to reboot, the new Wiley Fox logo appeared and then looped system errors i.e. "Unfortunately, system UI has stopped" , Unfortunately, the process com.android.phone has stopped etc
Can you give any insight as to my next move please? Would appreciate a noob response

Sounds like a problem easily fixed by doing a factory reset, have you tried that?
Just went today to try and factory reset through adb but now there is an "error:no devices found" - exactly the same conditions as yesterday

Hmm, is USB debugging on?
USB debugging is needed for adb commands. This setting you find in developer settings and to find and access developer settings you need to tap the version/build number 7 times.
How to Enable USB Debugging Mode on Android <- Check the bottom one #4
Once you do an adb command your phone may prompt you with a connection to pc message to confirm, go ahead and confirm it and do the adb command again.
But.. you need only to get into recovery mode and from there you select and confirm "wipe data/factory reset" and "wipe cache partition". You don't have to do an adb command.
https://www.hardreset.info/devices/wileyfox/wileyfox-swift-2-plus/recovery-mode/ <- I am actually not 100% sure if 5 and 6 are accurate but anyhow this should give you good enough idea on how to access the recovery mode. If in case you not already know this.
All your data will be wiped, make sure to do backup of things you don't want to lose.
May aswell also refer you to my post here, it's just an easy way of doing a fastboot flash.

I flashed stock via fastboot - But it got stuck on Wiley fox logo with process com.android.phone has stopped etc - hence it is not possible to go into the phone and turn on USB debugging, but it was on before I started the process - and I cant really do anything to the phone until I am able to get the PC to recognise the phone again

oh I see, and you've tried factory reset and cache wipe from recovery?
That guide I linked to says volume up + power button but I belive it actually is volume down + power button that needs to be pressed, like this. Try both ways, you don't need connection to pc for booting into recovery mode.
But this is different if you have bootloader unlocked, with bootloader unlocked you will be greeted with this (making use of warj04's pic) when you power on your device.
At this screen you press the volume buttons to change boot option from "Start" to "Recovery". Press power button to confirm boot into recovery and your device will reboot and boot into recovery.
This screen will appear a second time before booting into recovery but you need not do anything else, wait 5 seconds or press power button to start boot.

I have the bootloader unlocked and it behaves how you have described it but when I try and go into recovery from the options menu (power + volume down) it momentarily goes to a Wiley fox screen, then the loader (the image you added above), and then for a split second the green robot, then the screen blacks-out altogether. From the options menu I can also go to fastboot which also gives me the option to go into recovery but the same sequence starts as described before - recovery appears to be unavailable?

Yea by now I recommend you to redo the flash through fastboot again, In the thread post you linked to I only see 3 lines of fastboot flash cammands.
To fully fastboot flash a rom there needs to be a few other lines aswell, I'll list all the lines here.
Code:
fastboot flash modem NON-HLOS.bin
fastboot flash dsp adspso.bin
fastboot flash devcfg devcfg.mbn
fastboot flash aboot emmc_appsboot.mbn
fastboot flash keymaster keymaster.mbn
fastboot flash rpm rpm.mbn
fastboot flash sbl1 sbl1.mbn
fastboot flash splash splash.img
fastboot flash tz tz.mbn
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash cache cache.img
fastboot flash system system.img
Lastly, "fastboot reboot" to reboot your device.

You were a great help, thanks - I didnt think this was going to end well. I was wondering if I re-lock the bootloder will that intermitent screen dissapear? If so, How do I re-lock it?

Yes that screen will go away if you re-lock bootloader and if there isn't a dm-verity issue present.
To fix dm-verity issue you need USB debugging on and this command:
Code:
adb reboot "dm-verity enforcing"
If there is no dm-verity issue, great. No need for this command then.
The unlock and lock bootloader commands you do in fastboot.
The unlock commands are:
Code:
fastboot flashing unlock
fastboot flashing unlock_critical
So the re-lock commands are as simple as this:
Code:
fastboot flashing lock
fastboot flashing lock_critical
I am glad I could be of help
I have a Moto G Play 2021 (XT2093-4) (another one), that I made a mistake to relock the bootloader after I had it unlocked. I don't have access to the OS on the phone anymore. Previously I had the treble floss installed on it. I don't have TWRP installed. The only thing I have access to is fastboot. I realise I might have completely bricked this phone but I thought I ask here to see if there is any way to unlock the OEM again just using the fastboot.
the fastboot screen on the phone has a menu option to go into recovery mode. stock recovery might be able to restore your phone to working condition.
volume-down + power buttons > fastboot mode > volume button to 'recovery' option > power button to execute. if your recovery screen is broken with the 'no command' message, hold down the power button and quickly press and release the volume-up button. that should get you to the working recovery screen where you can try to factory reset your phone.

Thanks, but I think my phone is completely messed up now. If you can believe it, I can't even get to recovery mode. I can get to fastboot and then find the recovery mode and click to go to it but then it just starts the fastboot again. I'm basically stuck in fastboot forever. It's just weird cause there's nothing wrong with the hardware. Thanks again.
if you have nothing working on your phone but fastboot mode, that might still be enough to rescue your phone. boot it to the fastboot screen, connect it to a pc that has the fastboot program installed, open a terminal window on the pc wherever fastboot is, and type 'fastboot devices'. if your phone answers with its serial number, you'rr probably able to flash a whole stock rom to it piece by piece. get a stock rom from somewhere like lenovo, using their lmsa program, or just download the right one from lolinet or somewhere. unzip it. then, for instance, to flash the boot.img to your phone you would type 'fastboot flash boot boot.img'. that would replace your possibly broken boot partition with a known good one. then 'fastboot reboot' to see if that helped. there are tutorials on the net for flashing the rest of the rom. be sure to read one, because all of the flash commands aren't that straightforward.

Sorry for the really late reply. I tried what you said, but it fails right at the (fastboot flash partition gpt.bin) command and the output I get is:
Sending 'partition' (37 KB) OKAY [ 0.002s]
Writing 'partition' (bootloader) Validating 'gpt.default.xml'
(bootloader) flash permission denied
(bootloader) Cancelling 'gpt.default.xml'
FAILED (remote: '')
fastboot: error: Command failed
It keeps saying flash permission denied. I have another exact same phone with an unlocked bootloader and I did the same on that one and I was able to flash a stock ROM to it. I've tried every RETCA and RETUS on this site: https://mirrors.lolinet.com/firmware/motorola/guamna/official/ but it fails with the same error. I'm going to try all the rest later but it's a lot to download for now.
Thanks again for the help!
