Hello,
I have the following type device: CYXTECH_RK3188 909 V1_1 (CX919 II)
Android stick was working great with XMBC until the screen crashed and since then the stick is not able to boot anymore. CX-919 II is recognized correctly by ROCKusb drivers and i could flash different ROMS (standard and custom) succesfully. However when i connect the tv stick to my television only Google TV logo is shown and after a minute device is rebooting again. So now i am looking for the correct ROM which should work on my stick and advise how to get it up and running again. Anyone who can help me with this?
Thanks a lot!

I bricked my device too
I don't think you bricked your device; first, try using a different hdmi cable or different display/monitor
if that doesn't work, it might be a software thing, after some research on your device, you'll find some flashing tools which you can use to flash different roms, if that is the problem, go to this thread http://forum.xda-developers.com/showthread.php?t=2677979 , it is on rooting your device but i'm sure somewhere in the thread, you'll find the flash tool, if you don't, then download Finless ROM 1.6b (I've installed it on my cx919 ii 8gb rom, it is rooted and works perfectly [but there seems to be a bt problem]) http://www.freaktab.com/showthread.php?7553-UPDATED-CX919-4-2-2-Finless-ROM-1-6b
when you connect your device(windows only), you must manually install the provided driver in the file, don't let stu stu windows to install it, if you don't do it correctly, restart
here's how:
P.S. Yea... just hope you had the settings: usb debugging: off, connect to pc: yes/check mark, and connect as mass storage (not camera or mtp or something)
1. Open the flash tool (it should say something like: 'rk device not found' depending on the one u have)
2. Unplug your device from any power source
3. Connect a micro usb to usb cable to the otg port (i used a blackberry cable that was laying around, i believe the provided cable will work)
4. Then connect the usb to a port and imedeately press the 'fn' button (aka the one on the side)
5. Then in the device manager, manually update the driver for it with the one provided in the finless rom, be sure to update the device itself and not the drive/nand flash/ "memory"
6.Then in the flash tool, it should've found the device
7. erase nand memory/ idb
8. finally flash all the preselected items (that's how i bricked my device, when installing ubuntu, the files didn't have a recovery image so i couldn't conect it to my pc and reflash it)
Moment of truth, turn on ur device! u might wanna change some time settings cause some little problems with the rom like the time can bug u a bit
Hope it worked!
If i were u, i would do some more research, that's how i got this, u might stumble upon something and it might be a better guide then mine so just research it!
Now I'm gonna go find out how to fix mine!
Good luck flashing!

CX-919 II android TV stick bricked
Hi! I just purchased CX-919 II android TV stick. I was having wifi connection issues, so I decided to change the firmware with 4.4 kitkat. The problem was that when I was going to downgrade to 4.2 I had the usb debugging checked on. so now It seems my device is brick. the blue power light comes on, but the tv screen continues black with no sign og the system booting.
I´m RKbatch tool 1.7 and CX-919 4.2.2 Finless 1.6b with cx919-rk3188-4.2-6210-20131209 firmware
Can anyone help me unbrick my device, please?

Been there, done that.
When connected to the RKbatch tool, what message do you get?
Do you connect to a WINXP, 7, 8?
I messed my CX919II up when I flashed it using a WIN8 laptop. I tried everything to reconnect to my WIN8 laptop but with no luck.
I then tried on my old WINXP laptop and after installing the USB driver I managed to connect and flash my CX919II.
Now it's up'n,running again
Hope it works for you.
Cheers

Unbricking only with the short circuit mehod
I flashed it with win7. I already figured out what went wrong. it´s up and running again. I had to open the case of the CX-919 II / J22 / EKD03 Quad Core Rk3188 Android Smart TV Stick. Although it still connected to the RKbatchtool 1.7 it was always hanging up on the IDB preparing. - IDB fail. So I had no other choice but to short circuit the 7-8 pins of the nan chip in order to flash it again.
I´ll try to leave a detailed guide in this thread:
http://forum.xda-developers.com/hardware-hacking/android-sticks/cx919-ii-completely-bricked-tv-signal-t2859564
It might be useful to anyone who buys the CX 919 from ebay chinese sellers.

Short pins 8 and 9
I experimented with mine and unbricked it, Thnx everyone, but I figured it out already, just put a metal thing like a knife or a paper clip on pins 8 and 9,it worked for me, ur tool will see it as maskrom mode, this isn't very specific so unless u no exactly what I mean, don't Try it pls, (I'm really busy these days with homework) ?good luck

Hi All,
I have CX-919 RC-3188 clean stock rom with 4 gb ram if you interested in
thanx
*****DISCLAIMER*****DISCLAIMER*****DISCLAIMER*****
If you brick your device it's a whole lot of NOT MY PROBLEM
*****DISCLAIMER*****DISCLAIMER*****DISCLAIMER*****
With that out of the way enjoy
1) Download this
https://www.androidfilehost.com/?fid=95747613655047389
2) unzip: V510_4.4.4+tools.zip
3) Install the LG drivers
4) Install LGFlashTools v1.8 (but don't run it)
5) Copy MegaLock.dll to C:\LG\LGFlashTool, This is a hidden folder so enable "hidden folders". Replace the old MegaLock.dll file if you have already installed LG Flash Tool on your computer
6) Launch LG Flash Tool
You might see a window with Korean language, just click on OK
Check the Select Manual Mode on the top
7) MAKE SURE UNDER, DEVICE MANAGER, YOUR PORT IS SET TO COM 41 FOR YOUR DEVICE.
8) Click the DLL box and choose LHV510_SVC_LGFLASHv160.dll
9) Click the S/W box and select the firmware file with .tot extension
10) Now click the Yellow arrow button on the top left of the main window
11) Boot your V510 into Download Mode. To do this power V510 completely off. Then hold Volume Up + Volume Down + plug in USB to PC (in that order)
The firmware installation will be triggered
Ignore if you see any temporary error and just wait patiently till it is finished.
I took these instructions from another post. That post ended by giving "Credit [email protected] for making a cleaner guide for the TOT Method"
It's a shame the v500 can't be converted

+1 worked perfectly for me.
The only part that I had a little trouble with was changing the COM port to 41.
Windows users: you must be booted into Download Mode for the tablet to show up in Device Manager, where you change the COM port. I was trying to change the port while the tablet was booted up (normally) and it was driving me crazy.
Need some help:
tl;dr: Pretty sure I still need to flash the stock recovery, but having problems.
Coming from a rooted LG GPad GPE with TWRP installed. I followed the instructions on this thread and everything seems to have worked. I'm now unrooted, but I'm still getting "your system is up to date" when I check for an update in settings.
I think I do not have the right recovery installed, and that is why I am not getting the update. When I try to boot into recovery mode, I get the android guy on his back with a red triangle. No signs of TWRP being installed anymore.
I've tried several times to flash the stock recovery as listed in this thread: http://forum.xda-developers.com/showthread.php?t=2574639. It seems to work, but I don't think it is working properly. I also can't sideload the 5.0 file through ADB, since I need to put the device into recovery mode to do it.
---------- Post added at 02:24 PM ---------- Previous post was at 01:46 PM ----------
Nevermind. Turns out that is the stock recovery. Now my problem is I can't push the file over ADB. The ADB connection doesn't persist into recovery mode. I've followed the steps here: http://forum.xda-developers.com/showthread.php?t=2575783.
When the device is on normally, the ADB connection is fine. It shows up in the list of connected devices. When I reboot into recovery and choose "apply update from ADB" and then enter "adb devices" I get no devices connected.
In device manager, I see "LG-V510" under "other devices" but when I try to manually update the drivers to the google drivers as indicated in the post above, the computer says "Windows could not find driver software for your device."
Still need help...

I guess I'm not quite sure what you were trying to accomplish. If it is to install TWRP. You need to use fastboot from download mode and flash your recovery there, rather than trying to use adb from the recovery itself. "Fastboot flash recovery palman.img". , where palman.img is the name of whatever recovery you want to flash.
Fairly certain I did everything correctly according to the directions. When I press the yellow arrow about how long does it take to complete the install? When i started it, little box came up said some things that I don't remember and after about 30 seconds, the little box went away and the COM41 box says Ready!! Does that mean its finished? Just dont want to unplug tablet before the process is finished and brick it. Thanks
Nevermind, figured it out. Had to unplug device and plug usb back in and that triggered it to start.

No, I was trying to sideload the 5.0 upgrade. Couldn't get my adb connection to persist through to recovery mode. Finally figured it out and was able to get the tablet upgraded this morning - but I had to use the TWRP backup method. Everything seems to be good to go now though!
Correct drivers
I'm having problems getting the port changed to 41 and I think it because the drivers aren't installing correctly. Could someone confirm from the screenshot below that I'm on the right track, or maybe post a shot of what the correct driver set-up should look like? Thanks.
**Edit: Got it, I did have the wrong drivers.
I don't think you have the right drivers installed. There should be two of them and mine were both banged-out yellow, but only when in download mode and with the software running. You don't even have a ports tab to change it (or you have the wrong device).
I gave up and restored the Lollipop backup someone posted, which worked great except then I had to re-root and flash TWRP again.

If drivers are installed correctly, you should find it under Ports(COM & LPT) expand that and LG should be there. Right click and properties and find the COM41

I had given up for the 4.4.4 update when it initially came out and upgraded through TWRP, but now I'm running into issues with not being able to use the external SD card from the TWRP backup of LP that was posted, so I figured I needed to give this method a shot and do it right.
Any chance we will get the 5.0 TOT file for the v510? I tried following this guide: http://forum.xda-developers.com/showthread.php?t=2220801 and also tried using wireshark to capture the path in the LG Support tool but haven't had any luck with either method.
Thanks man. This helped me restore my G Pad when I thought all hope was lost.
Thank you very much, this worked perfect!

Hi,
I have reported this thread to be moved to the right Q & A section where you might be able to get help quickly.
Good luck.
This is why I worry messing around with my G2
Have you tried long holding the power button?
Sent from my Nexus 6 using Tapatalk
Same thing here. Any answers? I can hold the power button and it turns off for a second then turns itself on and these lines show up again. Same setup after using AutoRec on 4.4.2 rom.

Computer won't recognize the device at all, and it won't enter download mode. So I am not sure I can TOT back without that functionality.

Make sure you're phone is fully charged. I had a problem entering download mode with low battery. I also had to try different usb ports on my laptop for whatever reason.
Take the battery out, recharge it through an external charger.
Also enter download mode via inserting USB Cable (Make sure u have LG United driver installed) and keeping Volume Up button pressed for the whole time until Downlaod mode appears on screen, or atleast the screen is on with those lines.
In case of success (i-e. phone shows signs of life), go to Device Manager in ur PC and see if Android Device is connected. Use LG Flash tool 2014 to flash kdz back to normal or try the tot method just in-case your phone is D802/LS/VS variant which doesn't need download mode tbh, just healthy battery.

And sadly this was my phone. I switched for a while and was coming back and wanted an upgrade to the software. I hadn't updated from 4.4.2 as it had sat in a drawer, then did AutoRec (which I thought I had done before) and boom phone is completely unusable.

I can get signs of life (the bars), and windows makes the "you plugged something in and it worked" sound, but there is nothing in device manager despite having the LG drivers installed. Battery is healthy, I used the phone for a day or so to watch videos and stuff. I was working on it there. I think I need to try a different computer.

Expand under "Ports Com Ports & LPT"
And you will see LGE Com Port Device.
Just flash the kdz away if u see so. otherwise go through the tot method if u see the com port devices to change the com port address to com41 and then flash tot.
I tried this on Windows 10, Windows 8.1, Windows 8 and Windows 7 (all 64-bit versions) and it worked on all of those. Even with USB 3.0 supported laptop.
Your device is at fastboot mode at background, so use fastboot to erase and flashing img files.For example:
fastboot erase laf.img
fastboot flash laf laf.img
you just need your stock img files

Same problem with me tried Kdz Method. But no luck any idea? It's been 3 months em using it like this. Any help?
Sent from my LG-D800 using Tapatalk
So pretty stuck at this point as well. KDZ method stalls at 60%.
UPDATE FASTBOOT WORKING! Took forever to figure out the drivers, but it's working. I have no clue what to do now.
Fastboot won't recognize the device though I have the fastboot driver installed and running. Any ideas?
TOT is just kinda giving up on me. Still chasing down any leads, but the phone feels pretty borked at this point.
Update: Now in download mode! Man this has been crazy. TOT working! Okay so here is how I did it.
First, I downloaded google's ADB drivers and installed the LG drivers as well. I am not sure which one did it. Then I plugged my phone in and went to device manager. For me, it had an unrecognized device and fastboot wasn't working. So I had to manually assign the driver.
Right click on the device and update driver > Let me choose > all devices > Google > LGE mobile ADB interface.
Now fastboot should be working.
Then I used the srktool_2.1. Option 4 then option 4 again, select model number. It reboots to black screen. From there I was able to completely power off (10 second hold on power button). And when it booted back up all the drivers installed. I was able to TOT back to stock using this guide. http://forum.xda-developers.com/showthread.php?t=2432476. KDZ might work as well.
Unfortunately the screen damage looks to be permanent. But I think this is worth more now than it was 30 minutes ago!
Hi,
I initially soft bricked my LG G2 D801 by clearing everything in TWRP. Tried to fix it, went through a bunch of threads and tried different tools but ended up just screwing it up more, now a hard brick. Currently will not go into download mode or TWRP. In device manager it is listed as "LG Android USB Device". Also will continuously restart unless I go into "recovery mode" where it will go into Demigod crash. I basically give up because I dont know what I'm doing.
My proposal:
I will ship you the phone, you fix it and ship it back to me
I will pay you $50 for your trouble via paypal or check
Any other information you need from me to see if it is unbrickable?
Unbricked my g2 two days ago
Hey pal! I hardbricked my lg g2 d802 two days ago. The screen was dim and dark; I was already thinking about buying a new phone. Now im replying with it lol.
I went basically nuts because i couldnt enter into download or recovery mode
I thought everything was lost but through a tool called "srk tool" I was able to force download mode on the phone. (You have to toggle "nuke download mode")
Furthermore, if you happen to plug the G2 to the PC and come across the phone being recognized as 13 drives, srk tool has an option to unbrick the phone.
It would be great if you unbricked the phone. If you can only enter download mode, flash a stock rom. Ill leave you with the two threads which have guided me:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 (SRK TOOL thread, download latest version 2.1 and proceed according to your situation)
http://forum.xda-developers.com/showthread.php?t=2797190 (lg flash tool. Download your preferred rom or carrier stock, and flash the kdz freshly)
This is what has worked for me. Good luck
Hey!
Just wondering if you got it fixed. If not let me know. I know how crappy it is just let me know which carrier you have and message me if you want me to try n repair it. I screwed mine up badly after trying to get cyanogenmod to work too once. All I would get is an lg symbol then some texts. But I fixed mine.

thanks admin44, i'm def not smart enough for this. would rather pay someone $50 to fix it than have a disassembled phone that I cant put back together. =)
It is so easy just need some time and good eyes see some video on yotube how to open it .i do that before 2 month and i think i will need to do it again in futur becuase i love play on this phone i will search for some video that can help you
Can you take a shot of the demigod crash screen?
It's still a soft brick, hard brick is when the phone boots but the screen is black (panel gives light no image)
Can you double check in Device manager does it say something like Qhsusb_bulk?
@dudeimstoked , I've successfully unbricked the deepest of bricks on my G2 (demigod CH). I can help you. Sending you a PM.
Hey, as far as the it recognizing it as something else in download mode or whatever. Right click "this pc" on your file explorer and hit manage, it'll pop up a window and hit device manager then locate the phone and right click it and hit update driver software and hit select from currently installed drivers (could be worded different, doing this off head) and on the left it'll give you some manufacturers/corporations, select google and select on the right the one that has fastboot on it. Now if you don't see google in that list on left, that means you need to download and install the google usb drivers. This will help the computer recognize that it's in fastboot/download mode ready to get files flashed to it with the several programs listed above. I've had this issue before. Let me know if this worked!
My lg was not properly detected
My lg was not properly detected by windows 7 (plugged it in and nothing happened) and i was still able to use the srk tool. If you have qhusb... detected as the g2 you can unbrick. If it is not detected at all I would still try nuked download mode.
Good luck!! :good:
I really appreciate the tips here guys. I used to have the Qhusb_bulk or whatever reading in device manager, but in my trying to fix that I screwed it up more I think. Now I currently have what is shown in the images below. I've had a few offers to have this fixed for me, so I'll basically go in the order I received the PMs/posts. I'll do my best to provide everyone with enough info to make sure he/she can fix it without too much trouble.

Man I know how you feel, it sucks having a bricked phone. Anyways, I totally can relate to your situation. I had a hard bricked (Verizon G2), which I did repair on my own. At first I did spend hours on end going through forum after forum, method after method. All of them stumped me. Well after all the forums, I pretty much sat there on my own and tried to figure out the pieces. I knew that when we flash something to our phone, it has to flash to the motherboard. So a bad flash (hard bricked phone) means oh no the motherboard is dead since the phone is totally unresponsive. I ended up doing a motherboard replacement (yes I did take the phone apart myself and it was my first time), and success! The phone was revived. The process is definitely possible, but again it might not be the right solution for everyone. Just wanted to share my thoughts regarding this issue!
Side note: If you want to go this route I will need to order a motherboard for your model. Depending on how long it could take to arrive, it might be awhile before you get it back repaired. I will have to use the money to purchase the board.
all fixed. thanks to xmayhemreturnsx for the good work.
Please try enter to download mode and flas to stock kdz or enter to twrp and plug your pc if your computer seem the phone same mtp device copy a cyanegonmod rom and install
Hello everyone, first let me give major props to my man @bender_007 for creating the amazing LG G Series Autorec Apps which make installing TWRP on LG G Devices a simple process and for also helping me and others who ignorantly misused his app, thanks B!
Anyway recently I bought a LG G3 on Verizon that was on 35b 5.1.1 Lollipop and I rooted. Boy was I eager to get some TWRP poppin on this beast, however flashing TWRP thru Flashify and TWRP Manager left me unsuccessful giving me Secure Booting Error. So desperate I seen Autorec on the Play Store, installed immediately. From there I went through the app's proccesses and from there attempted to boot into recovery hoping for some success.... I did not realize this was went for 24b 5.0.1 until it was late, I mean hey he says it in the description. The phone was dead it wouldn't show anything on the display when I held the power button and it only vibrated, I was f***ed.... At least that is what I thought. I used the method below that me and @bender_007 were collaborating upon as he tried to help me. So please give him credit. I cannot guarantee this will work for you but it worked for me and you don't have to worry about opening up your phone and shorting pins, that nonsense if this works for you.

A FUNCTIONAL COMPUTER (PREFERABLY WINDOWS, I USED WINDOWS 7)

THE LATEST KDZ FOR YOUR PHONE MODEL (GOOGLE IT)
Your Dead but Still Amazing LG G3 and a USB Cable
Note: IF DONE PROPERLY YOU WILL STILL HAVE ALL YOUR EXSISTING DATA PRE-BRICK
PROCEDURE
1. Gather all materials, and know the locations of all your downloaded files.
2. Install the drivers for your phone.
3. Unzip LGFlashTool_2014.zip
4. Move the .KDZ you should've downloaded to the LGFLASHTOOL_2014 folder.
5. Open Device Manager (press start, type in Device Manager into search bar, hit enter)
6. Click View, "Show Hidden Devices"
7. PLUG in USB CABLE TO COMPUTER ONLY!
8. THIS STEP IS VERY VERY VERY IMPORTANT! TAKE THE BATTERY OUT OF YOUR LG G3. PUT IT BACK IN. CLOSE THE BACK. HOLD VOLUME UP ONLY, WHILE HOLDING POWER UP DO NOT LET GO PLUG IN OTHER HALF OF USB CABLE INTO PHONE. KEEP HOLDING VOLUME UP FOR 20 SECONDS. YOURE PHONES SCREEN WILL STILL BE BLACK AND IT SHOULDVE VIBRATED ABOUT 2 SECONDS AFTER YOU PLUGGED IN WIRE (You'll know when you do it right when COMPUTER says installing drivers in bottom right corner.)
9. In Device Manager under Modems there should be something like LGandroidNET I DONT REMEMBER EXACTLY THIS IS ALL OFF THE TOP OF MY HEAD. Anyway, if it says that then you are good, believe it or not your in download mode. (IF YOU DO NOT SEE THIS REPEAT STEP 8)
10. Go to LGFlashTool_2014 folder and run the LGFlashTool2014.exe application.
11. Change PhoneMode to Emergency
12. For "SELECT KDZ FILE" open the folder of the the FlashTool, it should be on it by default and pick the KDZ file.
13. Click "Normal Flash"
14. On the next SCREEN click "START" at the bottom
15. Now there should be a pop-up that says "Select Country & Language" Do not mess with this, just click "OK"
16. There should be a SCREEN now that has a % or whatever... From HERE TO THE END OF IT DO NOT UNPLUG YOUR PHONE!!!
17. When you hit like 85% your phone will boot up do not UNPLUG still and once it hits 100% your done! Safe to UNPLUG and YOU FIXED YOUR PHONE!!!!!!
If you have any questions please ask I have pure empathy for anyone who goes through this hell.
The first time I attempted to connect the phone I successfully had the phone under the modem tab. After being unable to find a .KDZ file (after a minute of searching) I stupidly tried another approach. Now after that not cooperating, I came back to attempt this again after finding a .KDZ file and am unable to set up the device properly to show under the modem tab. I'm following your instructions exactly and gave no luck. Any idea why this would be happening?

Okay I'm here to provide my best assistance and for that you'll have to answer a few questions?
1. What is your device model? ex. VS985 Verizon
2. What KDZ did you attempt to flash? ex. VS98547a_01.kdz
Looking forward to your reply.

@wombatthing I would go to device manager go to view "Show Hidden devices" then disconnect your phone take out battery put it back in close back then hold volume up for 20 SECONDS while doing that connect to computer. It probably won't say installing drivers because you said it worked the First time, from there see if it's under Modems. Good luck my friend in here for any questions

Will this method keep all my files that were stored in the internal memory? I'm not worried about the device, i just want my files! Camera pictures etc.
Edit. I tried it but in DIAG mode because i'm afraid emergency can delete my files? I can see the "LGandroidNET " but no vibration and seems like the driivers never install properly. My phone is completely dead.
@bender_007 @OneShotGoGetter
Thanks

My friend all is good. First of all as long as it says LGandroidnet you are good you should be in download mode, in lg flash took for mode click emergency and not diag then click normal flash THIS WILL KEEP YOURE DATA IF YOU SEE CRS FLASH OR SOMETHING LIKE THAT THEN ITLL RESET YOURE PHONE just do Emergency and Normal Flash and it should work. Hope I help if you have questions please ask.
@Ray1000 "Emergency" Mode is just Download Mode flashing. Diag is not that's why you were unsuccessful.
Thanks for this! I'm getting stuck at the end (step 16) when the flash tool says:
"Problem with communication between cell phone and PC.
Please disconnect the cable from your cell phone in order and remove and connect the battery. Power on your cell phone and press the Restart button to resume update. If LG Support Tool is stopped abnormally, try with [Options]-[Upgrade Recovery] in tool menu."
I've tried just clicking the retry button, and also unplugging the phone and putting it in recovery mode again before clicking retry. Neither has worked so far. Any thoughts?
Phone is D855, kdz version is D855V20b_00
For all people with Windows 10 an problems with drivers (device is detected by Windows but app is not connecting). Decompress de correct cab for your Windows version, and update the driver "Qualcomm HS-USB QDloader 9008" with the path you used to extract. Now this driver isn't advertising that isn't signed anymore, and all apps will connect with your LG G3
Qualcomm HS-USB QDLoader 9008 2.1.0.5 x86
Qualcomm HS-USB QDLoader 9008 2.1.0.5 x64

Sorry for the late response. First of all you are welcome. I don't know if you fixed the problem yet but I'll help anyway. First remove youre battery for at least 10 seconds then put battery in, hold up and connect charger for 20 seconds. Of you are unsuccessful try reinstalling drivers. Best of luck my friend.

Hi, I have tried your method but get stuck on "Problem with communication..." Is this a problem specific to windows 10?
I have attempted to update the Qualcomm HS-USB QDloader 9008 but cannot see it in device manager.
Any help would be greatly appreciated!

Hi,
Thank you for this post. But unfortunately I can not get back my device. What happened was I bricked my phone while flashing TWRP. It's a G3 D855 and does not power on at all. Screen is blank, no LED or vibrate. I tried volume up/down combinations with power button but nothing happens. However when I connect it to PC, device manager shows it under Modem and COM ports.

I tried to flash a stock ROM using your method. But I got following error during process.
The only problem was phone did not vibrate when I connect it as you mentioned.
Do you think my phone is gone forever? Is there any other way? Appreciate a reply.
Thanks!
i also cannot find the Qualcomm's driver on windows 10 & phone looses communication with flash tool..

He guys thank you very much. My LG3 was already down for months after many failed attempts and I was about to bin it. Decided to give it one last try, found your instructions and it works, I now have Marshmallow!! (However I downloaded the KDZ file from "downloadmirror.de" and I am not sure if that was a good idea.
