Hey guys,
I got a little problem:
Got this amazing LG G3 on 4.4.3; got it rooted. Updated to 5.0, got stuck in a boot-loop. Tried couple of things and now im stuck on the reboot
Saying this:
[690] Fastboot mode started
[780] - reset -
[780] - portchange -
[920] fastboot: processing commands
I can access download mode.
I've tried using the LGFlash tool to flash the tot file using my Rogers D852 files - the tool says check phone or dll and that the device model is different.
I've also tried using the LG flash tool 2014 to flash the kdz file witch I got from the link with the imei - first it says cant connect that shuts down after couple attempts.
Dont know how to fix this problem
Any suggestions?

The thing is I can get into the download mode but for some reason cant restore the phone from there
In download mode phone is visible in device manager as LGE Mobile USB modem? If not update LG drivers from http://androidxda.com/download-lg-usb-drivers. Did you try different usb ports/cables?

Well I suggest using the LG Suite and try to install a new update but it will remove root. You can root it again( I believe) and its not a hardbrick( like mine) so you should be fine with the update.
lg suite solution
I already try that solution with lg suite but after phone restart whole process is stooped i i have the same alert screen that i had when i try manually go into download-mode. so secure boot error, boot certificate failure or something.
Pushing files under linux via dd command
Hi guys right now i prepare some files like boot.img, aboot.img and also laf.img so kernel. boot-loader and download mode.
But right now when i check i`m not able to find under Linux my G3 i doesn't have any additional storage devices except hard-drive.
Right now my phone is able to work in few modes:
- When it turn on and boot normally (sometime): i can connect it as MTP, PTP, and charging ( but update via lg suite don`t work)
- When it don't turn on at all (boot-loop) - it`s not recognized by windows at all
- And sometimes when I leave it in boot-loop for more or less 5 minutes it goes to some orange screen that with subsystem error kernel crash and after i push volume up i theory i`m in Dload mode and phone is recognized in windows as LGE with com port but i cannot use LG flashtool 1.8 (error when model version checking, and in lg flashtool 2014 error of phone connection and process is stopped)
Any advice?? how to make phone to connect as qualcomm... to make it recognized by Linux
Hi guys,
I was running CloudyG3 2.5 on my D855. Today I wanted to go back to stock using LG Flash Tool with D85520h firmware file (lollipop) (in Windows 10). It got stuck at 4%. After waiting for close to an hour, I just unplgged the device. Now when I power it up, I get the secure boot error message and it starts blinking the notification LED (alternating red and blue). Going into download mode also brings up the same blinks, as does attempting to go into recovery mode.
All the threads I have gone to seem to assume that the phone can boot, or enter recovery mode or enter download mode. My phone can do neither.
I desperately need help.
Thanks in advance

Thanks a lot mate. I used the willcracker tool attached in the OP of the thread and it worked like a charm. My phone could go into the Qualcomm HS-USB mode but one of the following factors could have been at play:
1. The BoardDiag tool I was used was fake (as mentioned in the thread you referred me to.
2. The PC I was working on has all ports as USB 3.0 (I'm not sure if that was issue or the fact that I had other devices connected-- just a mouse adaptor, but I could see my phone in Device Manager)
So, I went ahead and changed all of the above: used the newly-found BoardDiag (willcracker), on a another PC with a USB 2.0 port and made sure no other devices were connected.
My phone is now back to life!
Hello all,
I've done a lot of googling and searching on these forums and I'm having no luck. Hopefully by asking I can get some headway.
I was attempting to restore to stock rom. At 17% of the process using LGFlashTool 1.8.6 the tool gave me an error 'Unable to Communicate with phone' after about 10 minutes of no progress. I exited the LGFlashTool program and ran it again and now it fails saying 'Cant' change to download mode". If I turn the phone off and then press Vol+ and plug in my cable it just goes to the Firmware Update screen. My phone *IS* detected properly in the device manager as LGE Andriod MTP Device and under ports as LGE Mobile USB Serial Port (COM41). If I go into recovery (Vol- and power) it asks if I want to do the restore - but it doesn't actually do anything once I say yes twice. Just sits at the firmware update screen at 0%.
I looked at this post (http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091) but it appears to be either for a different phone or different problem (showing in device manager as a bulk device - mine is not doing that). Frankly I don't want to make things worse (if that's possible)
Does anyone have a way that I can restore the download mode for this D852 phone? I'm hoping if I can get download mode to work again I can reflash the stock rom. I don't care about the data on the phone at this point.
I'm willing to send some $$$ via paypal to whomever can get me back up and running! Thanks

What happens when u just power up the phone ?
Thanks for the reply.
If I shut the phone down (by pulling battery) then plug it back in and just power it on, I get the LG logo then it goes to the firmware update screen with 'USER B84" in the box below the progress bar. Progress bar never moves. I get to this screen whether I start it in recovery (which is just the factory recov - looks like during the initial 17% it wiped out my TWRP), attempt to start it in download mode (I do not get the download mode screen with the blue dots anymore), or regularly by just holding the power button.
ok
Dont plug it into the computer and try to power it up what does ot do?
Same thing.

Ok that didn't work for me but I did try the LGFlashTool using Board DL instead of Upgrade DL and it was moving a bit. Finally got to 10% and failed at 574 sec with the error "We can't communicate with Phone". I am using the cable that came with the phone. It isn't damaged or anything.
Here's what is shows in the LG Flashtool window (this is port 1 (com41)
Code:
PID: BS09S150309001007
IMEI: <myimei>
Model: D852

On the phone it shows COM41 under the usb icon on under firmware update and 0% progress. In the box below it says:
Code:
F USER 50.0 A50.0 B70 UHS
S U LG-D852 04.4.2 Hrev_10
D85210b
D85210b
That's it. Should I leave the phone connected at this point or unplug it? Device still shown in device manager (have had it up beside the LG Flashtool window the whole time. I do see it refresh from time to time but the contents dont' seem to change at all.
Ok so I left this over night and when I checked the phone this morning it's different but I don't think it's good.
Looks like it proceeded but ended with:
FBOOT Check
FBOOT Complete Time [0s ] 1th try
Factory Reset Flag = 2
Factory Reset Flag Check Fail!!!
And my phone has a blue screen with Factory Reset Status and a big red '2'
Now what do I do?
Some further information.
If I run the LGFlashTool in Board DL action mode, it seems like the process works but I end up with the red 2 on the screen. But I don't get 'can't change to download mode' or 'cannot communicate with phone' errors.
However if I choose Upgrade DL action mode, then I get 'can't change to download mode' or cannot communicate with phone'. ARGH. What gives?
I have tried things like fresh restarts (restarting PC), restarting the LG FlashTool between attempts, not restarting flashtool, etc. I can't seem to find the sweet spot.

http://forum.xda-developers.com/sprint-lg-g3/help/fix-bricked-lg-g3-ls990-stuck-fastboot-t3084562 another tutorial to try
Thanks, but no dice.
I don't get fastboot options, and if i download and attempt to use fastboot, it shows no devices.
Also, when following the steps for the BOARD DL option in the lg flashtool, it goes through the process but I get no ATT screen. Nor do I get the option to tap OK or Normal - as soon as my device reboots after the flash, it gives me a MINI OS (iirc) screen with a bunch of vertical bars below it moving up and down then it changes to the Factory Reset screen with the number 2.
last one lol
http://androidforums.com/threads/ho...-2-lg-g3-d855-twn-32-gb-problem-fixed.911271/ i found one more that could help it said to use a jdz not a tot hope it helps if not sry
Thanks - I'm going to give this a try, however I can't finda .kdz file for my phone (canada/rogers D852 LG G3) - the links in that post that link to firmware is for a tot file. Does anyone have a link to the KDZ?
Hi, I'm having the exact same problem now, where the phone only boots to the Firmware Update screen. Did you manage to fix it?
Indeed.
I used the KDZ method pacods61 posted last, but I had trouble actually finding kdz firmware. With some help I finally managed to do so from here: http://devtester.ro/projects/lg-firmwares/country.php?country=Canada

Hello Gurus,
Well i am trying to boot my phone into download mode but i am continuously getting
secure booting error 1014 and my phone then boots lollipop 5.1 which is stock rom.
my lg g4 model is h81510h build number lmy47d, it is not rooting or flashed anyway.
I want to flash flash marshmallow kdz with lg flash tool but my phone is not booting into download mode, please help or suggest any other method
HALP PLS
I'm having more or less the same problem. I bought a used H815 and it came with Android 5.1 (software version h81510h)rooted and stock recovery. I tried upgrading to MM over OTA but tapping Update Center leads me directly to the App Update screen instead of giving me a choice between software update and app update.
That is when I decided to go the KDZ route but when i tried switching the phone to download mode it went there and in the top left corner there was this 'Secure Booting Error 1014' message and then it restarted in about 5 seconds. I have tried this multiple times with the same exact result.
ADB detects my phone but when I send the 'reboot bootloader' command it just does a plain reboot so I can't use any of the fastboot commands. I also have no idea whether this phone has an unlocked bootloader or not.
Also for some weird reason my phone is not using the MTP mode when I connect it to my PC. It either uses PTP or charge-only depending on what I select but if I select MTP it automatically reverts to the previously selected mode. LG Bridge doesn't detect it and neither does the Mobile Support Tool but I can transfer images just fine. MTP was working last night but it suddenly stopped working and I have no clue why.
I can get into the recovery without any problems.
Please help me get it working again

Any update ? I am also facing same issue. One wierd thing I noticed that adb devices displays phone as "LGLS991" can you tell me your result of adb devices ?
Im having the same problem.
Lg bridge, lgup and flashtool not detecting my phone. How to flash my phone with any os? Kindly help me
Same problem with my H811. Any solutions?
I cant get my g4 into download mode. I was able to earlier but it died on me. My buddy has the same phone so I am using his fully charged battery now (mine was around 40$) but I'm still getting nothing. Should I reformat the SD card and try again? I can't think of anything else.
Hello everyone reading! I've tried many guides here, but none seems to work for me somehow, thats why im writing this post.
Whats my problem?
- I've been having this problem for a year or so now, like most softbricks im stuck on a bootloop while launching the phone, with red and blue led light flashing.
The message displayed in the top left corner of the screen says:
boot certification verify
Secure booting Error!
Cause: boot certification verify
How i have bricked my phone?
- I remember i have tried to unroot my phone after having cm installed, can't remeber the version though. Then the phone just got stuck in the bootloop and wont launch along with recovery.
What have i tried?
- I have tried flashing the phone to stock via lg flash tool (tot and dll) and Lg Flash tool 2014 (kdz) no luck unfortunately.
- While flashing stock F400L rom through tot files im having sometimes Milkyway connection failed error when im launching the program, but i don't think that's the case.
I'm doing everything in right order, drivers and programs installed, going into download mode, changing ports to COM41 or COM1 (neither works), launching lg flash tool 2014,
choosing suitable for F400L stock dll and tot then launching the process, unplugging the phone and after 5 seconds plugging it again.
Nothing happens, im stuck at ready.
- Tying to flash through kdz file seem not to work either, got errors after l start the flash process.
Phone plugged, in download mode, yet i get the message of program not being albe to access it, like it would have problems with connection to the computer.
Im following the instructions that program gives me though it does not help at all. It stops after reaching 4% and asks to connect the phone back after checking connection with the device.
Thanks for any help provided!
