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:

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
Direct link for D852 Rogers Lolipop 5.0.1: http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FWF448V332CPAKX8CEA4UCE/D85220g_00_1205.kdz
Looked everywhere but couldn't find an answer to this problem.
My LS990 was on a MM ROM with TWRP recovery. I tried to install an app from another phone with Titanium Backup (Install App + Data) and it hung for a long time and then shut off. When I turned it on, it got to the startup animation and the froze. I removed and replaced the battery several times but always with the same result. Trying to boot into Recovery Mode got me to a blue screen, then it shut off.
I went into download mode and tried to flash LS990ZV4_04.51101 stock with LGFlashTool (which I have done before successfully). It only got to about 60% before stopping and shutting off. Now whenever I turn the phone on, after showing the LG logo it goes straight to the Firmware Update screen (without showing "download mode" first).
When I press Volume Down + Power it shows "Recovery Mode - loading..." for a couple of seconds and then shows Firmware Update.
On Device Manager the phone shows up as "LGE Mobile USB Serial port" (not AndroidNet)
When I tried flashing stock again with LG Flash Tool it gets to 38% and hangs forever. (done this several times)
I have pictures but XDA wont let me post outside links yet.
Is there anything I can do besides trying to short the pins?
I see that when I connect the phone to the PC without the battery inside it shows up as "Unknown Device".
Could I perhaps do something with that?
Hey everyone,
I did something really stupid while trying to get a certain app to recognize a codec that it needed in order for it to work and seem to have probably bricked my phone.
Phone Details:
LGH812
Lollipop 5.0.1
rooted
I went to /system/ and renamed lib64 to lib64bak because I wanted to put some new files in there. This caused the phone screen to immediately go black and unresponsive. I took out the battery and re-inserted it. The phone boot logo with LG comes up and then it goes to a black screen with the dead android guy with red triangle and the exclamation mark. No other text is present in this screen. Stays at this screen for about a minute and reboots only to go back to the exact same screen.
Things I have tried:
1.) I tried to boot into download mode (power+volume down) still goes to the aforementioned screen.
2.) Got LGUP to recognize the com port once, but it shows up as unknown and won't let me proceed with a fresh wipe/install
3.) Tried the LG Flashing tool, couldn't even see the com port.
4.) Tried the WHQL universal drivers as well as the specific device drivers with no advancement.
What I believe is happening is that it's trying to boot properly initially, but it can't find lib64 folder so it fails to launch the os and then tries to go into recovery due to error, but fails to go to recovery also because of lib64 is missing.
If anyone has any ideas/things I can try to get it into recovery or download mode or if anyone has seen this state before and was able to fix it please let me know.
Thank you all for your time!
I was using a D850 on Fulmics 7.6. This morning, my phone crashed unexpectedly. Tried to restart it, but it will stay on for a minute, then dies again. Tried to go into recovery to reflash Fulmics but again: on for a minute, crash. Someone suggested trying Lineage OS, but that one keeps getting errors mounting the SD card and whatnot. Tried to wipe all partitions and try again, still nothing. Tried to go back to stock, successfully got into download mode and started LG Flash tools, but I get a Download Failed error. After that, download mode wouldn't work anymore. Tried using Androidbrick G3 unbrick, and was able to get Download Mode to work again (goes to the firmware update page), but still LG Flash tools failed again, and now it won't go back into Download Mode. Should I throw in the towel at this point?
When I do plug it into the computer, I do see the Download Mode screen, but then the display turns off and in my device manager, the phone is a Qualcomm hub 9008 or something like that.
Owned 65P8e for 3 years and worked fine until today when i plugged it in and standby light was rapidly flashing and then says "No command" and loops on and on and on.
I downloaded and plugged in a usb stick with "V8-R851T02-LF1V302.013602_IMG_USB_GMC.zip", I unzipped it properly into img and it did state sucessful install
However after it finishes installing it goes black again and then the standby light flashes again, repeating the installing process.
I tried removing the usb and starting the tv again, now it says "Error!" instead of "No command"
Any form of help is appreciated, thanks in advance.
Try another flash drive. If it doesn't work out, take a more recent firmware, there are enough of them!!! I once sat for half a day to install.Of the 4 flash drives, only 1 came up.Loaded from the shelf.Good luck.
