D851 Hard Brick

I cannot boot into download mode and cannot boot into twrp. The phone will not boot no matter how long i hold the power button and there is no lights. When connected to the pc it shows up as Qcom Dload. Can someone please create a debrick.img. All you need to do is flash this in twrp and send me the debrick file which should end up on your sdcard.

This has been tried before and it didnt work for the guy. Have you tried flashing a tot? It has the begining of the emmc so same outcome but you can skip all the sd card work. Good luck if the tot fails and no one steps up ill get you that debrick file just to see if your luck is better.

That was a no go i tried the older dll that bypass model checks but still fails. Guess there is a linux method that worked on the older g2 and someone with a g3 reported success so i already extracted the TOT files i need to dd over from linux.

Yeah that's probably your best option I have a partitions dump from the tot if yours are not working for some reason. Instead of installing twrp If I was you I would boot into download mode after and flash the tot. I did do a debrick dump with the script that I can get to you tomorrow some time and if that doesn't work tell me and I can give you a link that has 250-500mb range for the dumps from when I was helping the other guy. They weren't made with a script but with terminal emulator but they should be the same thing just bigger because the smaller dumps weren't working for him. Any way here are the partitions just in case https://www.androidfilehost.com/?fid=23622183712472493

Oh and before I go to bed another thing you can try if you can send the images over but they don't seem to work. Hunt down the fastboot laf.img send that over then do the rest of the partitions via fastboot instead. Good luck!

Dead phone
Dead in the water. Only qpst seems to see it besides device manager (Qualcomm HS-USB QDLoader 9008). The linux method was for people who get the lg logo. I don't get anything but a black screen. Problem is i don't know enough about the qpst software to guide you on making the files. All i can say is try to make a backup using qpst and provide links. Don't know what else to do.

In order to get you the files someone needs to reboot from the hidden menu into somthing I cant remember. Its not mini os and the d851 lacks the option in hidden menu atleast I didnt see it. The d855 hidden menu has the option and I was going to try it but he ended up sending it in before I got around to flashing the d855 rom. If you want to fix it yourself and can do without a cell phone for a few days I can try but might not be able to get you the files until sunday if it works.

Yeah i will have to wait then can't afford the $175 deductible right now. Thanks for the help. I don't mind waiting just hope i can find a less costly solution know what i mean?

QPST
So it looks like i will need a hex file and mbn partition files vs the bin files that come from the tot file. From what i read in the forums lg offers a 1 year warrenty. So i guess as a last resort i could send it in for service but i would rather try to resolve it myself.

Qualcomm MSM8975AC
Hello
I tell them my story, mistakenly doing a ported rom stock LG G3 Marshmallow, I flashed my phone with the stock rom from Marshmallow (model D855) and after that I have bricked the phone. No download mode, no emergency mode, only is recognize for the computer as AndroiNet usb port serial.
Could please you help me to unbrick my lg g3 Phone model d851,t-mobile variant. When I plug in my Phone to computer, this is recognized as lgandroinet port serial but I have made a testpoint (open the mobile) to change the phone mode to Qualcomm HS-USB QDLoader 9008”. I have used tools like boardiag but I get the followin message: “No response from the device. Check PMIC first and if still boot problem, replace AP.” To look at this thread: http://www.androidbrick.com/unbrick-recover-your-dead-lg-g3-g2-all-variants/ ... but report that it is not compatible for ATT and Tmobile variations. I currently have two virtual machines: Window xp 32 bit and Ubuntu 15.04. My client OS is 8.1 Window 64 bit.
I will be very grateful if you can help me to find a solution or can show me which is the correct way. I've been several weeks looking for a solution but I have not been able to fix my cellphone. I hope that my computer still recognizes it.

Hello,
I will try help you, first of all you must to change the Qualqomm mode in your phone, namely change usb LGE Androinet by QDloader 9008. For this you must remove the battery from the phone, open the phone and use copper cable or tweezers and you must to touch two points on the mainboard in order to force Qualcomm mode on your phone. I have attached photos to guide you in this process. You must touch two points (without battery) and connect the usb cable to the computer. You'll hear a sound that indicates that qualcomm is active otherwise could see a battery warning on the screen. If this happens, you must disconnect the usb cable and repeat the process.
The second thing you're going to do is install the drivers appropriate for Qualcomm mode. Please follow this thread: http://www.droidsavvy.com/unbrick-qualcomm-mobiles/
This is the download link for the drivers referred to the post: http://forum.xda-developers.com/attachment.php?attachmentid=3261089&stc=1&d=1428980071
Now your computer will recognize the cellular in the indicated mode (Relink HS-USB QDloader 9008).
The next step is to use the Boarddiag tool in this post but in the root folder, place the file sbl1.mbn which is located in the folder that you extract the file TOT.
I am currently uploading a package that includes bordiag tool, sbl1.mbn file, and TOT file extracted. When the upload is complete, I could tell you what is the download link, this contain the version of Boardiag that will work in our model. Currently my phone lg g3 D851 (chip MSM8975AC) was revived.

I'm not sure if it will work for your model, please performs the tests at your risk. Let me clarify that this is the same boarddiag version , only I try added the files needed.
Within the. 7z, there is a file called "TOT Extract", please extract it and open application BoardDiag. In the section "Target Dir" choose the path where you extracted the file.
Please inform me as it was with the tests.

Thank you SOOO much for your help so far.
I installed Qualcomm Drivers and touched the points and it connected.
But it says that the Drivers are blocked due to not being digitally signed.
And it's showing up in Device Manager as "Qualcomm HS-USB QDLoader 9008" with an exclamation point.
I am posting screen shots.'
You didn't have this issue?
What steps do I do in the BoardDiag exactly? Just add the directory with the file and hit start?

@mxpxboi it seems you're using windows 8/above, you have to disable driver signature, here is how to do it https://learn.sparkfun.com/tutorial...abling-signed-driver-enforcement-on-windows-8

Device will not turn on LG G3 D855 32GB

Hello everyone.
I need your help.
My Device: LG G3 D855 32GB
The device does not turn on, the only thing that appears is because when I connect the device to a PC, I see a driver installed:
RELINK HS-USB QDLoader 9008
I read guides on site here, and I'm trying to order
I downloaded the software BoardDiag 2.9
I downloaded the files to the appropriate TOT
I extracted the files by instructors on site.
I opened the program and I followed the guide and it seems to me an error
Download mode is enabled Mode,
I quickly disconnects from the computer and reconnect the computer and then the moment I am unable to do a test and the results are:
AP CHECK START = PASS
EMMC TEST START
FAILED TO OPEN PARTITION FROM EMMC
TEST ABORTED !!
I tried a lot of tutorials but I can not, it always seems the device is in Download Mode
What can I do more?
Please your help,
Eliran

If you go that way, you will need bunch of other stuff. Here is the link
http://open-freax.fr/guide-unbrick-your-lg-g3/
It is a good thing that your PC recognises phone like that.
But first be sure that You can not enter download mode or recovery or even fastboot.
And please say what did you do to make it like that? Wrong flash?
If you CAN enter download mode than you can flash kdz or tot files from there. Easiest way is to use LGUP but you must be careful if you want to try.

The phone fell

I am exactly in the same situation. Have you found any solution so far???? My phone suddenly stopped working and didn't boot up at all first and then I used the LG Flashtool to install original TOT file and all went well. I forgot to close LG Flashtool and it started flashing again. LG Flash tool restarts the phone at about 80% and then it failed at that point and since then I am having this issue.................

[HELP] G3 Hardbrick Help! URGENT!

Here's my case:
I've got a LG G3 F400L (Korean LGU Variant), its on Marshmallow(6.0), and for all I know I used the Autorec program for Lollipop, and apparently got my bootloader corrupted; No led flashing, no display. But the Qualcomm 9008 serial port is shown on the device manager and I can use Boardiag to detect it. I know, irony and idiocy made this dilemma.
Diagnostics:
I've used Boardiag 2.99a by willcracker and yes I've checked "AP check" and "EMMC TEST" and both are tagged as "Pass", but when it comes to the "SDRAM TEST" it throws off an error indicating that there is a flash error on partition "boot" along with a 0x3000 and I can't progress beyond that, I've also tried to use the "Restore Device" option to revive it but still the later error still persists.
I've also tried Smart Boot Diagnostics but the problem is that my device's AP Chip doesn't exist on the current version of the tool.
What I would like to press on:
I would want to resolve this on my own and that no amount of suggesting on sending this to the service center would yield fruit. Please do understand, I would also like this to be a thread that can help me and other on resolving their corrupted bootloader units.
Please, can someone help me on my dilemma. Thank you very much. Any amount of help is appreciated.

Try using board diag with the battery unplugged.

Already tried that but still nothing works.
Current situation:
Alas, I've accessed fastboot and had wiped the boot partition, but now the USB is detected as "LGE AndroidNet USB Serial Port."

You need to short with a cable internet connection I do this last night and changes for Qalcomm USB in the same time...After that, you need to open BoarDiag and do the process. If you can´t enter in download mode, you need in BoarDiag pass the USERDATA

Bricked R800x - QHSUSB_DLOAD

I have an Xperia Play that I got off eBay (I know, I know, personal project - I do have another working one). Reported issue was that it wouldn't boot, but after messing with it, I found that it would 1/10 times if I pull the battery for a few seconds before trying. I was even able to flash a stock firmware again. However, the majority of the time, it won't boot into OS, fastboot, OR flash mode.
Here's why: QHSUSB_DLOAD
From my research, this basically means the bootloader is corrupt or somehow otherwise malfunctioning. When connected to a computer, it resolves to "Qualcomm HS-USB QDLoader 9008 (COM3)" or whatever COM port it lands on, and it does this in fastboot and flash mode. Except for those rare instances where it acts like a normal phone.
I've spent most of the past couple of days digging around in forums, Google, and the Wayback Machine, trying to find a solution. Unfortunately, beyond trying a different computer and reinstalling drivers (both of which I have), the only solutions given are to use Omnius or s1tool/s2tool. They both seem to require payment for unlocking phones, which I don't need, but as far as I can tell should work fine for repairing the s1 boot, which I think is what I need to do. I've been following different guides that all say to remove the battery, connect the test points, and plug in the USB, but I can't get Omnius or the s-tools to work.
Is there any hope for this device? Can anyone who has gone through this before offer some suggestions? Alternatively, is there maybe a way I can just deal with the problem while still being able to use the phone without needing to pull the battery a bunch of times? The Xperia Play is still a great portable gaming system, so I'm hoping we'll be able to figure something out, as I know many other people are starting to acquire these from eBay and try to get them working, and may also run into this issue.

I'm also having the same issue.

Here's my problem, I wanted to flash a new ROM into my R800a but when I plugged it into my computer it detected the phone as a device called "Qualcomm HS-USB QDloader 9008" and now it does not turn on anymore .
Searching around Google I found that it doesn't turn on because the "SEMCboot" or "Trim Area" is damaged, but I've no idea how to fix that on my own.

Sometimes we can brick our devices by a bad unlock, flashing process, or simply bad luck.
The phone doesn't turn on and there is a Red Led Of Death when pressing power button. Even with a GREEN led when we plug the phone with back key pressed the computer detect the phone as "unknown device" so there is no chance to get fixed by Flashtool or SEUS/PC Companion.
Well this problem normally means that the bootloader is broken or damaged. So, in order to fix it we need to write a new SEMCboot and after this we were able to flash a full and fresh firmware with flashtool and unbrick our Xperia.
This process like unlocking process requires SETool dongle/box and a paperclip to make a testpoint to put the phone in flash mode and be able to write the SEMCBoot.
I can help to anyone with a bricked Xperia Arc/Play/Neo/Pro just make send me a PM.
Like unlocking process you will need this 3 programs:
SETool software for unlocking
USB Over network client for remote dongle
Teamviewer client for remote support and guide
THIS PROCESS IS FREE

Some of these fixes and threads are old/outdated, so I dont know what will work Ive already started to use some of the tips last night. I have found out that my phone does get detected as "Qualcomm HS-USB QDloader 9008" but that's as far as Ive gotten. Please read the threads and tell me what you find out, or try that works

I've already been through those threads, and several more like them. The immediate answer is to contact Alejandrissimo, but they've been MIA for years now. I shot them an email the other day, but I don't expect to hear back.
Things I've tried:
Xperia Companion (PC Companion) - doesn't recognize device
SEUS (Sony Ericsson Updater Service) - discontinued, can't connect to servers
S1tool testpoint method - doesn't recognize that a device is connected
Omnius - doesn't recognize that a device is connected
Flashing stock the one time I could get it to boot into flashmode
It looks like this method stands a good chance of working, but it requires an "APPSW .sin_file_set" file, which I haven't been able to acquire for the Xperia Play. From Googling around, it seems that's the blob file that gets downloaded when you get an OTA update or when using XperiFirm (which no longer gives Xperia Play as an option), but all I can find are recompiled *.ftf files. Those files do contain a bunch of *.sin files, but comparing the contents to what you find in a *.sin_file_set file, is too different; the latter has a different folder structure and a bunch of XML files that provide information to the phone. I'm not sure exactly just how necessary that structure is and I couldn't find a guide on recreating a *.sin_file_set file, just how to decrypt one to convert to FTF.
If you click that link to the tutorial for that process, you can download a *.sin_file_set for a different model of phone to see what it should look like.
Of course now I just stumbled on a guide to convert FTF back... I will have to try that.
EDIT: Okay, I grabbed the s1tool from that link and disabled my antivirus before using it. Did the testpoint procedure as described, and got this error:
llbug: [] open error: "The system cannot find the path specified"

That might be because the bootloader is still locked. If I can get it to let me into fastboot, I may be able to change that.
EDIT 2: Got it into fastboot, verified the bootloader is locked. Ran the unlock command, but it failed. Tried doing it through s1boot and got the same error as before. Guessing there isn't anything else I can do at this point.
EDIT 3: Forgot to mention the process I tried before was with an FTF, since I discovered S1tool will use those after all (I used the version from that website I linked to). I still need to recompile a sin_file_set version and try that. In the meantime, I did actually receive a response back from Alejandrissimo, so we'll see where that goes and I'll report back.

Help with Hardbricked g4 h735ar

Hello, I need help with my LG, the cell phone ran out of battery while updating firmware, now I cannot enter download mode, nor fastboot, and the recovery does nothing, when I turn on the cell phone it always ends up in a black screen with a text of the type "CMD" putting a number and something of "udc_start" and that's it.
windows 10 makes the normal beep but does not recognize the model, in the device manager "android device" appears with the warning sign that there are no drivers.
LGUP does not recognize the device
The only way I had to "make windows recognize it" was with "QFIL" and touching the two pins on the motherboard, in the program it says:
"qualcomm hs-usb qdloader 9008 (com4)"
I have never flashed a cell phone bios or a bootloader if I misunderstand (I am relatively new to android), I have only flashed "the operating system" in this case a 1gb .kdz
I have no idea how to do this, if I don't misunderstand, I need a .mbn (I think it's the bios), which is compatible with QFIL, which I couldn't find in all of google.
I've come across other .mbn of "similar" g4 models, I wonder if it will work if I at least try them.
They may not work perfectly, but at least turn on.
What do you suggest? I feel lost in an ocean t-t

I'll take a look at it, thanks

Seems like a similar problem as I had, that's not gonna work though. The only way to fix it is to use a firehose which you can use a one from a Cyanogen MSM8939 device.
