Hi all,
My LG G5 is in a bootloop and I cannot even access the recovery.
I guess I made something very, very stupid. Can anyone help me? Please??
Here is what I did:
- Android 6.0 stock ROM (v10i)
- Encryption is on
- unlocked bootloader
- rooted using the official LG way => everything worked fine
- installed latest TWRP => everything worked fine
- entered TWRP and installed Nougat bootloader (LG-H85020K-Flashable.Bootloader.zip) from the v20 upgrade (I actually planned to installed FulmicsROM-4.5 and the manual said I need the Nougat bootloader)
=> bootloop
The device keeps saying "The device software cannot be checked for corruption. Press The power key to pause boot". I did that and ran
fastboot devices
on my Windows PC, but no devices showed up. I have used fastboot in the past, so I am sure that the drivers work.
I also tried LG Bridge, but it does not detect anything.
Does anyone have any idea how I can rescue my device?
Regards
Clarenze
Yippee! I found a solution:
- install LGUP + drivers
- turn off phone
- hold VOLUME UP key and connect USB connector to PC => Phone displays "Firmware Upgrade"
- start LGUP => LGUP detects the phone and allows to flash a kdz file
My phone works again and the day is saved!

Hey folks,
its bricked due to FOTA (I think it stands for: firmware over the air) update. This means the phone downloads a firmware update without computer connection or further PC-Software. Alas it didn't work.
Situation:
Phone starts, displays LG Logo and after that an 'updating firmware' screen for about 1 sec before rebooting and doing it all over again.
What I tried to solve this:
set up a new Win 7 32 bit machine to try to unbrick it. (drivers didn't work correctly on 64 bit) at least the MCCI driver update didn't)
connected the phone with the PC in Emergency Mode (holding VOL_UP + VOL_DOWN + PWR while USB is connected)
downloaded B2CApp (LGSupport Tool) and installed the device drivers for Emergency mode.
disabled the Android(Modem) dirver
downloaded V10D_00.kdz from LG home page
using the phones IMEI and this link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI_NUMBER_GOES_HERE
This gave me this link
http://csmgdl.lgmobile.com/swdata/WDLSW/LGE720/ADEUBK/V10d_00/V10D_00.kdz
I'm German so this seems all right, but I'm no expert​
installed msxml
ran KDZ_FW_UPD_EN and tried CDMA in CS_EMERGENCY Mode
A bunch of magic happend until the phone restarts during the process and is right back where we started, if I put it back to Emergency Mode while KDZ_FW_UPD_EN is still running the process finishes, but to no avail.
The log of this try is attached.
Where I am stuck now:
phone:
runs in Emergency Mode
is recognized by KDZ_FW_UPD_EN as well es LG Support Tool
Flashing via KDZ_FW_UPD_EN finishes
Flashing yields no result.
What else did I try
download V10C_00.kdz, as well as V10A_00.kdz from LG site and tried those with same result as with V10D_00.kdz
tried 3GQCT Type instead of CDMA
Wild guesses by me:
I need a different KDZ_FW_UPD_EN version, maybe different dll. I got it from here somewhre in a LG P500 related topic.
I messed up the driver install or need a different driver
LG hates me personally and planted this whole brick specifically to get to me.
The device really is permanently bricked, so I did all I could and there is nothing more to do? That would be sad, I hope I'm wrong here.
Additional Info:
The phone is not rooted and has never before been flashed. It ran with the same stock firmware since it was unwrapped.
The phone was not interrupted by power-loss during FOTA update.
The [read phone information] tool from KDZ_FW_UDP_EN crashes every time, maybe this tells somebody where things go wrong
Any help is appreciated. Ask for more info, if you need it.
Update - What else did I try:
I got the LG Support Tool to flash the Emergency Recovery all by itself runs till 99% --> reboots --> still stuck in same ol' bootloop
reentering Emergency Mode from the bootloop makes the Emergency Recovery finish with 100%, no error, but still bricked.

Like many others i recently got trapped into 'Security Error' problem and phone was refusing to boot-up.(after root i deleted some system apps )
luckily i found the solution
this guide should work for other LG's phone too.
so here are the steps:
1. update/install USB Driver for windows
2. now enter into "download/emergency mode" of your phone... but how??
(i) remove battery then insert battery
(ii) press and hold both vol+ and vol- buttons and connect to computer via data cable. you will see LG logo and '>download mode' on bottom of mobile screen.you will also hear a 'connecting sound' from PC that indicates that your phone is now connected.
3. disconnect the phone from PC(remove data cable) and install LG MOBILE SUPPORT TOOL
4. run that B2CAppSetup file, it will install LG SUPPORT TOOL online so wait for some minutes.
5. now in main window of LG MOBILE SUPPORT TOOL you will see "waiting for connection".
View attachment 2934639
6. connect your phone to PC (via data cable)
7.LG TOOL now should try to connect your phone to it, so wait for few seconds.
View attachment 2934640
8. now in LG TOOL got to 'OPTIONS' > 'UPGRADE RECOVERY'
View attachment 2934641
View attachment 2934642
9. make your self a cup of coffee or take a nap if your internet connection is too slow because it will download approx.500-600 MB of software and automatically install it on your phone.
(if your upgrading stuck at 4% then disconnect the phone and connect it again in 'download mode')

there is a another method too using kdz but that didn't work for me Flashing KDZ on LG L5 II
PIECE OF ADVICE: never ever try to delete any system app of Stock Rom otherwise you will get 'Security error' (not even after unlocking bootloader) and let me know if there is any solution to it.
tested guides by me on LG L5 ii e450 on win8.1:-
-for rooting [Guide] Root LG Optimus L5 II E450
-for CWM recovery (L5 II) CWM for Locked Bootloader(Beta 2)
-for unlocking bootloader (L5 II) Unlocked Bootloader (Optima Team)
Actually I've done it with locked bootloader and it's still working as a charm.

I did everything as shown but im still stuck. When i turn device one lg logo shows up, after a few seconds it spins around and i can hear boot sound, and lights turn on. I left it like that for about an hour but its still stuck.
device: LG e460
Thinking myself to flash orginal recovery. Atm thinking about booting into recovery via minimal adb in usb debug mode
Reason: i fail to boot into cwm since month with my e440. Recovery reboot wiget never worked also expeliced xposed model for this LG4ii has no boot into recovery option.
minimal adb code something like
adb devices #enter
adb reboot bootloader #enter
fastboot devices #enter insteat of fastboot may recovery or download
#in fastboot mode you can flash files by
fastboot flash recovery recovery.img #enter flash recovery.img

It seems the program just doesn't want to find the phone. I don't think it had Usb debugging enabled(Think that's the problem), cause its not my phone, but I have also tried changing usb ports, from usb2 to usb3 and restarted the phone. Any ideas?
It's great! Everything worked out without "stucking on 4%". The "security error" appeared on LG E450 after "rooting" and deleting some system apps.
Many thanks to author.
Hi!
I'm so stupid. I wanted to install cm12.1. So I rooted phone, unlocked BL. Then, I had first problem - when executing adb oem-unlock BL has unlocked and phone go to fastboot. But my comp couldn't recognize it (heard plugging in and out sound repeatedly). And here comes my "stupidity". I installed flashify and flashed CWM by it, got to CWM, installed cm12.1 zip. Of course wiped all data. Because I didn't flashed boot.img cm12.1 was freezing on fist setting up screen (nothing was working, just power button - pushing 10s turned off phone).
I wanted to flash boot.img by fastboot. But I still had problems with drivers(omap4boot didn't work). So I tried to recovery system by LG Mobile Support Tool. Everything got fine, but then phone stuck on the LG logo.
S/W Uprgade mode works of course, but I can't get to recovery now.
I'm using Windows 8.1
Any ideas?
Edit.
Ok, so I tried to install omap again. I did it, but the phone is still repeatedly conecting and disconnecting and in device manager I cought omap4430 driver whith waring mark for a while. Any ideas now?
Is it the non-animated LG logo?
This should work:
http://forum.xda-developers.com/showthread.php?t=2748384
The download links for the firmware are probably not up to date. Use this to download: http://forum.xda-developers.com/showthread.php?t=2287573
If your phone still goes beyond the non-animated logo, there might be easier solutions.
It was after animation.
Anyway, I have finally solved this problem by installing new system using Bride's solution with full wipe.
Good evening, I have in my hands a smartphone lg p778g does not pass me the logo to light following a simple copy of the folder whatsapp internal memory to the microsd (it was blocked after you copy and to restart it and did not initiate more ... it stays in the LG logo when turned on and there does not pass.
I tried to hard reset with vol (+ or -) buttons + home + power but rather than get out the menu of recovery I get the doll android slept with a triangle exclamation and there is no way to enter the menu that tightening no buttons.
Then I looking for information online found the utility tool flash, did all the steps as marked, I installed the drivers perfectly, the PC detects me the phone without problems, but always in the middle of the update (put the mobile mode s / w upgrade ) 50% program lg cancel the process by saying that there has been an unknown error and try try again by disconnecting and connecting the mobile, but no way, I give retry to to try again and again it hangs at 50% and I jump the error screen again.
I wonder if there is some other program where you can do the hard reset this phone than by the official LG utility, or by microsd.
The operating system used is Windows 7 64-bit, disable the Windows firewall and antivirus and run as administrator utility tool flash lg 2014, but always the same. I also tried running the utility lg mobile support tool directly to you directly seeking the most updated for lg p778g firmware, but it's the same as using the lg flash tool 2014, the 50% of the upgrade stops and gives me the message error.
A greeting and I hope you can help me, I need the phone !!
We'd need someone with a p778g. The problem may be be caused by the special branding of the phone, or an encrypted bootloader. Or the internal flash got completely cleared, partitions and baseband rom, which means a full brick. Otherwise flashing stock in D/L mode should work, even if anything else fails. But this goes mainly for LGs official tool working online. With the LG Flash Tool 2014 i had also problems.
I think both tools have to ways to perform the unbricking. Either with the phone put in D/L mode by the user (if Fastboot don't work on the PC), or by recognizing the phone (but with a still running system) via ADB, then auto-switching to Fastboot. And you should also be able to attach the phone when it's already in Fastboot mode. The latter methods don't work on both my systems under Win10. When my desktop pc had been upgraded to 8.1, i performed all servicing of the L9 with my netbook, which was still on Seven.
My last unbrick was months ago, and i don' t know what happens at 50%. It's something important, and knowing it may help to understand the nature of the problem(loss of contact between phone and pc before the actual process starts, errors during flashing...).
It could be like this:
-phone seems to get recognized by driver&tool, that is good
-image gets downloaded(only with the official tool)
-image gets temporarily extracted on the pc(both online and offline). I fear that by completing the extraction the 50% mark is reached, and that no actual writes to the phone can be performed.
And LG's stock recovery, which calls itself "service mode" or "s/w mode" can be mistaken for D/L mode. I'm talking about the D/L mode, which is also present with a custom recovery, but theoretically D/L mode, S/W mode and Fastboot could be used for unbricking

Hi,
my LG-D160 is rooted and with twrp.
In the past i installed an unofficial Cyanogen 11 for LG-D170, which was not fully working. So i restored the backup with twrp which i made before Cyanogenmod flashing with twrp. In the hardware information of android i could see the model name "LG-D170", which is wrong. The phone seems to work.
Now i want to flash stock rom kdz. I use the lg flashtool 2014, Windows 10 64 bit.
If i start into Download Mode / Firmware Update (by pressing the "volume up" button and connection the USB cable + also holding "volume up") and start the LG flashtool 2014. In the flash tool "software upgrade in progress" stops at 2% and tells me to switch of phone, put usb cable .... and to "retry".
Any ideas ? Thank you.

Try to manually flash the files, see if the volume up mode recognizes your phone in fastboot, if it does, you can try out my tool (https://drive.google.com/open?id=0B6vSHGXxJIWmVjRVMlRSQW9HWWs) and from there you can manually flash it.
You need to change the info on the build.prop to the correct model before the Flash Tool will work.

adb shell on my LG-D160 phone:
in /system/build.prop:
ro.product.model=LG-D160 -> So it seems to be right.
On android GUI:
system settings -> hardware information -> model tells me: LG-D170
So iam confused.

Looking at an install guide for the cm11 rom, I see that you are supposed to have flashed another bootloader. That is probably the issue here. You would have to see if you can find a way to just flash the stock bootloader and then try the Flash Tool again.
http://forum.xda-developers.com/lg-g2/development-d802/fix-lg-flash-tool-stuck-2-t3031112 - this is for the G2, but wondering if there might be some info there that could help point you in the right direction too.

I restored my backuped stock boot and recovery partition with the adb shell / dd. The modelname in android -> settings is now correct "LG-D160". The flashtool already stops at 2 % and tell me to "retry".
fastboot devices shows also nothing in the firmware update screen ("power up" button mode) after restore of stock boot and recovery partition.
Thank you for your link.
