[Nexus 5 General] svetoslav2:
I have a problem. When i try to install the software. I get that "Download Fail!"...i`ve installed everything correctly, i`ve tried all my usb ports...nothing. And the most intresting thing is that, lgflashtool says that may phone is D820, but it is D821... Can someone help me :)
[Nexus 5 General] bitdomo:
You are using the D820 dll and not the D821 dll.

The other thing is that lg flashtool says your phone in unknown mode. Is your screen turned on and showing the screen what is posted in the first post?
[Nexus 5 General] svetoslav2:
No i`m shure that i`m using the d821 .dll and also yes its in download mode(the second screen where it says "Firmware update")
[Nexus 5 General] bitdomo:
Redownload the dll, please. LG flashtool clearly says you are using the D820 dll. Also take a screenshot in device manager about the Ports section
[Nexus 5 General] svetoslav2:
Ok, i`ve done what you told me to do. This is what shows up:

Edit: one time it says its d820 and the other time it says that its d821. And i`m using the same .DLL(d821)
[Nexus 5 General] bitdomo:
Everything seems fine now. The dll is shown correctly the usb device is at com41. Have you tried it on other pc or different usb port? Avoid using usb3 ports
[Nexus 5 General] svetoslav2:
On a diferent port(usb2) yes...but on a diferent pc no. OK...i`ll try on a diferent pc or directly reinstall mine :D and i`ll tell you what has happen :)

[Nexus 5 General] *boy*racer*:
Hey people. Just ordered the Nexus 5 and like to get everything set up ready for when it arrives. I have followed the instructions and thought i would test it and load the files to get used to what to do. Now when i select the dll file i get the error "Wrong dll file". Is this because i haven't got a phone connected yet?

Sorry if this has been asked many times. It's just that i am coming from Samsung Galaxy S5 and all this is new to me.

Hope to hear back soon as the last post is from the 7th :-S

Thanks
[Nexus 5 General] bitdomo:
Hi!

Download the dll file again and try it again. It should not tell you that it is a wrong dll. By the way this method considered as plan B to return stock. I know it looks like more familiar because of odin. If you really want to set up everything before your phone arrives then check this thread http://xdaforums.com/google-nexus-5/general/resource-guides-info-threads-linked-read-t2784527 it is a collection of guides. The most important thing is adb and fastboot for nexus devices http://xdaforums.com/google-nexus-5/general/noob-read-adb-fastboot-how-hep-t2807273
[Nexus 5 General] *boy*racer*:
Thanks bitdomo. Just uninstalled everything and started again and this time no error :). I will definitely check those links out. Thanks again.
[Nexus 5 General] akenis:
Hope I can get some help here. Been tracking you here from numerous other "bricked" threads.

THE CULPRIT: While running stock, rooted on multirom with elemental kernel, I used the app Flashify to flash the stock kernel.

BRICK: No boot. No recovery. No Bootloader. No Display.

Biggest problem is I don't know what mode my device is in. But it does appear in device manager. Usually it's the USB section as "USB composite device" that is unable to start. At one point, with various button presses I did see it under ports as "Qualcomm HS-USB QDLoader 9008 (COM5).

So what state is my device in when I see USB composite?

What state is my device in when I see the QDLoader?

Do I have a chance of getting my Nexus back to life? Just got it back from LG with new screen!!!
[Nexus 5 General] bitdomo:
Remove any usb cable

Press and hold power key for 30 secs

Release power key

Press and hold volume up, volume down and power keys at once. If you dont see any sight of life your phone is bricked and no chance to revive it. If you end up im fastboot then reflash stock rom from google.

You were in a secondary rom when you flashed the stock kernel with flashify?
[Nexus 5 General] akenis:
Using your key combo....nothing shows on display. I haven't seen anything on display.

I was in primary ROM when I used flashify to flash stock 4.4.4 kernel.

Looks pretty good per your guide, but nothing happens with the LG Flash screen. (Also had to do some weird adjusting of PC clock and enter registration key).

The driver shows as LGE Mobile USB serial only after manually updating from Qualcom QDL Loader...

So how much does LG get this time?
[Nexus 5 General] varuntis1993:
I guess the motherboard cost. Which cost around $200-250 here in India. International pricing should not be much different.
[Nexus 5 General] bitdomo:
When LG flashtool says "READY!!" you have to reconnect your phone.

Have you edited your build.prop file or anything?

Because of those brick things like what happend to you I avoid to use any app or toolkit to flash anything to my nexus. I always use fastboot or flashable zips to flash kernel or anything.
[Nexus 5 General] meangreenie:
from your screen shot it looks like it's in download mode there (com41).. have you tried running the tool?
[Nexus 5 General] akenis:
No edits to build.prop. It was rooted stock with custom kernel on primary of multiROM.

I've tried reconnecting device with "READY" displayed. Tried holding all three buttons down until it disappears in device manager, then just holding down volume up.

Problem is, I doubt it is truly in download mode. The LG drivers did not automatically install per the guide. I right clicked on my QDLoader device and forced it to the LG driver, and set it to port 41.
[Nexus 5 General] meangreenie:
if you look at he g2 general forum you should find a big thread on how to restore partitions when download revovery are corrupted... might be able to grab the laf.bin/img from the n5 tot file and flash it using the same method.. this will give you download mode back
[Nexus 5 General] akenis:
This one?

http://xdaforums.com/showthread.php?t=2582142

Do you guys think it could work? Would be a lot of work. Need to install VM for ubuntu, and even then I don't know linux at all.

So it seems that "brick" is a very vague term. Some get stuck in boot loop and they're bricked! How bricked am I? Is there a chance that my hardware is all good? Like I said, I never see anything on my screen. But, I am able to get device recognized as QDL Loader. What exactly is that?

Also, above, you would try just laf.bin/img and then go back to procedure in this thread instead of restoring all the partitions mentioned in the G2 thread?

With a chance, I might give it a try. Thanks.
[Nexus 5 General] bitdomo:
It only works when your phone is in qualcomm 9006 mode. Sadly your phone is in qualcomm 9008 mode.

Jtag is not a solution since jtag port on the motherboard is disabled in the Qfuse table. You cant change and efuse value. It is like the warranty counter in samsung devices.

3 soultion remained:

-Buy new phone

-Buy new motherboard

-Find connections to the emmc chip on the motherboard. Solder wires to the connection points. Modify an sdcard reader and solder the other end of the wires to the modified sdcard reader. Then you can reflash your bootloader.

The last option is really really hard. The resistors where you can find connection points are so small and also they are covered with some kind material which first have to be removed without tearing off the resistors or damaging tne board.
[Nexus 5 General] akenis:
Thanks! You saved me countless hours fiddling with VM Ware, Ubuntu, and cursing. Would have been neat to resurrect though.

Now I just have to go to PO and send back to Dallas.
[Nexus 5 General] meangreenie:

Regarding my brick:

I had copied this log file from Flashify to send to Dev. The first instance is from a different device I had used. It shows up here because I had used Titanium to restore the app and data to my Nexus.

The log shows activity when Flashify failed to backup kernel on Nexus 5. I asked Dev if this failure was related to multi Rom? I was just wondering if there was any evidence here (logged partition information) that might reveal the reason for it later wiping out my boot loaders and download mode?
[Nexus 5 General] Jounsa:
Hello all,

My Nexus 5 is in a bootloop where we cannot enter Download Mode, Fastboot Mode, Bootloader Mode, and surely not Recovery Mode.

It loads to the "Google" screen (1st screen) and then restarts. When Vol Up + Down Buttons are pressed with Power Button, it temporarily loads to Bootloader Screen, then restarts.

Was hoping that Flashtool would solve my issue, but without being able to enter Download Mode, I'm stuck.

Can someone please help me?
[Nexus 5 General] joecool666:
hi, power off, just vol up and insert USB let your pc install driver's only if your useing lg-flashtool and start again with flash, maybe someone could verify this, hope this help's regard's joe.
[Nexus 5 General] Jounsa:
Hi Joe,

Not able to do that either. It continues to bootloop once it's connected. When not connected to a power supply (laptop or charger), it is dead to the world, but as soon as juice is given to it, it goes into an eternal bootloop.
[Nexus 5 General] joecool666:
maybe you could try "nexus root toolkit" hope tis help's. it has maybe a fix for soft brick and bootloop,
[Nexus 5 General] Jounsa:
Think I tried that as well. Seems that the circuit board shorted or something. Will carry it to a hardware repair shop.

Thanks though.

Hi,

My phone's button stopped working just inside system.

In bootloader's menu and when force reset it works.

Tried to flash using LG Flashtool and nothing.

Anyone knows what may be?

Thanks
[Nexus 5 General] bitdomo:
you tried and nothing is not much information to solve your problem.

Have you installed the drivers?

When you enter download mode do you see a bootlogo saying download and then after that another screen saying firmware update with a progress bar hanging at 0%?

Have you changed to port number to 41?

Have you reconnected your phone after lg flashtool says "READY!!" in the COM41 window?

Do you can any error message from lg flash tool?

Have you tried flash stock rom in the normal way with fastboot?
[Nexus 5 General] allsalvati:
Sorry, here what i have tried:

1 - I flashed a zip with stock rom

2 - I flashed stock images with flash script

3 - I formatted all partitions in CWM recovery

4 - I flashed stock Kit Kat image again

5 - I flashed Android L preview image

6 - I flashed with LG FlashTool

The phone booted fine everytime i flashed, but the physical buttons didn't worked.

I can reset the phone using button's combo, i can access the options in bootloader's menu, i just can't use the buttons inside the system.

Thanks
[Nexus 5 General] allsalvati:
I don't know exactly what happened, but now it's working.

After flash with LG FlashTool i turned off the phone for a while then i accessed the bootloader's menu to see if it's blocked.

When i started the phone the buttons worked as if nothing had happened.
[Nexus 5 General] harsh2193:
I'm not able to boot into download mode. I pressed the volume up button, held it down for a few secs (tried instantly as well) and then plugged in the usb cable, but the phone still boots up into the bootloader and the volume button press causes it to keep switching between the bootloader options.

Hi guys,

I did

everything

as posted in the begining of this thread and still when I start flashing I get this annoying error (see attched file)

does this mean my partition is completly corrupted because it always says "userdata erase fail"?

got the same problem with the Nexus Root Toolkit by the way where it says "flash write failure"

so this probaply means my Nexus 5 is really bricked right? I'm thankful for any advices.

greetings,

edit: I found another thread with the same problem > http://xdaforums.com/google-nexus-5/help/nexus-5-flash-write-failure-t2693128

so it really seems like a hardware problem! only solution is to exchange the partition manually :(

There is a crack folder after extracting lg flashtool. You have to replace the original megalock.dll with the one from the crack folder
[Nexus 5 General] haoleflip:
Followed directions to a T. Can't figure out what I'm doing wrong for the life of me.....
[Nexus 5 General] bitdomo:
Your phone is in factory mode. You have to boot up a custom recovery then run these commands from your PC's CMD or terminal window:

Then open misc.img in a hexeditor. Go to 8800 offset.

You will see a text something like this LGD820AT-00-V10b-NXS-XX-OCT-31-2013-KRT16M-FACTORY-16G+0

Make that text look like this LGD821AT-00-V10b-NXS-XX-OCT-31-2013-KRT16M-USER-16G+0 (I mean just replace the text from the "-" sign before the FACTORY word with the words of USER-16G+0 text)

Dont be bothered with the additional +0 at the end of the text.

Save your modifications.

Go back to CMD or treminal and type these commands:

Then you should be good to go with LG flashtool. If you dont want to do this then use fastboot method to flash stock firmware.

If you get the dll file and tot file for lg flex then you can use
[Nexus 5 General] ohad129:
Sorry i didnt got what you mean?
[Nexus 5 General] bitdomo:
You need the dll file for lg flex and a firmware file (tot file) for lg flex then you can use lg flashtool with lg flex
[Nexus 5 General] ohad129:
Is there a problem to get them?
[Nexus 5 General] bitdomo:
Yes, because these are restricted files for LG which should not been accessed by everybody. Luckily, LG Flex has kdz files. From kdz files you can extract the dll then the only thing you have to find is a tot file which will be hard to find. I think you should use lg flashtool 2014 http://xdaforums.com/showthread.php?t=2797190 because it can flash kdz files and you dont need dll for flashing kdz because kdz files already have the dll encoded.

'LGE Mobile USB Modem' driver fails to install

Hi,

When I plug in the phone and the computer starts installing the drivers, among the 3 drivers that are being installed - the 'LGE Mobile USB Modem' fails to install and the other two are installed correctly. I tried going ahead with the process mentioned but it failed on the 'LG FlashTool'.

How can I install the 'LGE Mobile USB Modem' driver?

[Nexus 5 General] yoncy:
Yeah, seems that Download Mode was removed in Lollipop, you cannot enter in it with Volume Up + USB cable combination. In order to work you need to be on a 4.4 rom. I flashed a 4.4 factory image. Also on windows 8 if you have exclamation mark on drivers in Device Manager -> browse for drivers in computer and point to the LG Electronics folder from Program Files(x86 i think). That folder has the specific driver files and then they will be recognized.

What? It still works. Just hold vol down and power.
[Nexus 5 General] bitdomo:
It is from LG Notification-Korea SVC Center. Looks like download mode got disabled somehow (maybe with the new bootloader or with some flag). As I see download mode will come back later, but it will wipe userdata after confirm entering download mode as per google requested.

I have HHZ12h verison of bootloader. It came with the 5.1.1 andorid update. If I can guess download mode works for those who are on older versions of bootloader.

Invalid response command type...

00000064

And the phone's screen freezes at 99%.

When I try to flash a fresh stock image with fastboot interface only can flash Kitkat images, Lollipop images stay stuck in the "flying color dots" screen.

When I try to do a Reset Factory from TWRP always I receive the message "failed to mount /cache".

The phone starts with Kitkat but it can't write over internal storage, and Google Play Store crasesh, Gallery app crashes, etc. When I connect the phone in my PC, I can see the internal storage but I can't write anything in the internal memory.

I'll appreciate your comments.

You dont need usb debuging enabled to use fastboot. You can use the tutorials about return to stock rom using fastboot. If you still having bootloops check my signature, the solution for bootlooping is there. It is the second link.
