another "i think i bricked it" thread, please help

I have been running several rooted roms on my gs3 for a while and have been enjoying the phone very much. Today I decided I would switch from cm10 to slim. I booted into twrp and flashed the incorrect rom (I flashed the i9300 and I should have flashed the d2att, though it claimed the flash was successful)
I know that was stupid and I am aware that I should have read more carefully, etc.
So after searching a few threads it looks like I just bricked my phone and will have to send it in.
But just for completion sake, here is what I see.
-The phone will not boot up
-if I plug the phone into my computer I see a device called "qhsusb_dload" under device manager
-if i hold down+home+power when booting up, the phone does not go into download mode
Any help? advice?

I'm very sorry to report that you are bricked...
On a side note, that qhsusb_dload is some type of download we haven't been able to communicate with... Possibly in the future, unbrick methods will surface using that connection... You need Jtag repair...

EDIT:
Also, are there QHSUSB_DLOAD drivers or is that just the GS3's way of saying "nice job idiot, you screwed me over"? I cannot seem to find them if they do exist...

That's for the I9300, but with the right files, I747 files, and that method, it's probably able to bring it back... Unzip a stock .tar and see if all of those exist...
There's got to be drivers for it, but none that have surfaced... Most likely internal Samsung stuff, and they just click a couple buttons to unbrick...
Try installing QPST version in the IMEI thread, it may install a driver... If it does, you can establish a COM port connection, and POSSIBLY, through methods not been done already bring it back...
And this is all hypothetical....

Well I found some drivers and now the device appears as a usb to serial (COM3) titled "Qualcomm -HS-USB QDLoader 9008". Seems promising?

Nope. This was a problem even at the Nitro HD forums, you got QHSUSB_DLOAD you're screwed. I remember one of us could make a connection, but it was raw RAM write/read; we'd have to locate the exact address for the boot image and system IMG in order to revive it. Better off JTAGging, I think Samsung may do it for free. I know LG did.

That's for if you can get into bootloader mode... go and get a stock ODIN for your phone and use 7zip to unpack it... see if it has all those files, boot, csc, phone, etc...

LG G3 cannot turn on or enter download/recovery mode

Hey guys ,
I'm new to here. Searched everywhere for this issue but haven't seen any real solutions. Got an LG G3 here. Less than A month old. Owner left it on doing some app updates overnight and she woke up the next morning and it could not be turned on. She dropped it off at a fixit guy who said he tried several firmwares (even the official LG one that he said he had to pay close to 100us for :/ ) and still nothing. She was really pissed as she bought this brand new wth only 14days warranty which is up and it's basically bricked. I told her I'd have a go with it but I was unable o go into download or recovery mode. Windows detects it as a Qualcomm Usb loader of some sort.
I was wondering if there's any way to manually format or recover this using Linux or Mac OS. I have all three OS so any help I can get to get this booted up and running would be of great help. I'll donate to the one who led me to get this stupid thing working again. Thanks! ?

Yup. Tried it before. Tried it again. Nothing. What's next ?

Update: somehow windows doesn't detect my phone as Qualcomm anymore. It's seen as 'unknown device'

Isn't the phone still under warranty? I had the same problem and used the manufacturer warranty (1 year) and you only to pay shipping

Well QPST still recognizes the phone as a device but there are no data that can fix the problem on the motherboard. Tried to used the kdz file and it recognized the phone but there was no data like the modem or the IMEI to recognize it. As a result the only way you can fix it if somehow you get all files from modem to boot imgs. Tried that for two weeks straight and no solution. So apparently gave up and gave it to LG. There are no solutions at this moment

Help soft unbricking lg g3 d855 [no download mode and PC can't recognize it]

I was factory resetting phone because it was having some problems with the camera, and that's when I accidentally dropped it, causing it to soft brick (I can turn it on, but it stays on the LG logo, and as I said, I can't enter download mode. However, I can access recovery mode). The problem is that I can't make the computer to recognize it (when I connect it, it doesn't appear any port option, only the universal serial bus controllers followed by an "unknown device". This happened before I bricked my phone.), which makes the situation even harder. Besides opening it and retrieving the mainboard, is there any other option? because I'm not 100% positive that I'm not going to be able to do that. PLEASE help!
*I'm not an expert with phones, so if there's an answer, try to say it on the most detailed and basic way, if possible

Dropping it wont cause a softbrick in your case theres two possiblitys either A u droped it and damaged internally or B when u dropped it the battery fell out while resetting and uve corupted a file but probly the first. Either way this guide is for the g2 but it may give u some insight. http://forum.xda-developers.com/showthread.php?t=2582142

I would rather go for
-USB OTG cable
+
-USB FLASH driver with some rom on it

Didnt think of otg in most of my travels most people never even heard of it ill get u the site if u want it i vet em 75 cents apiece ive never tore one up always end up losing them

I forgot to mention, but when I dropped my phone, the battery DID came off, so the factory reset did get interrupted

If thats the case at worst lg flash tool back to stock using ure kzd or tot file but u should be able to do steps above

I downloaded a stock firmware for lg g3 d855, stored it in my sd, and when I launched it in recovery mode it said "Failed to sysmapfile '/external_sd/download/<name of the rom>.zip".

I did everything and nothing happened. I pulled the battery, put it back, hold the up button and then plug usb and again the lg logo came for a few seconds, followed by a charging battery animation. Once I plug in the usb, I hear the typical windows sound that you get when you connect a device, but it says that an unknown device has connected.

My problem is that my PC won't eecognize the phone, so when I execute a command in fastboot mode, the window stays in < waiting for device >, and I guess that stays until you connect your device.
Also, I'm having trouble understanding the concept of fastboot mode, is it the same as download mode, recovery mode, or it has nothing to do with that?

I didn't had the same issue as you, but had a similiar one (phone didn't get discovered neither by LGUP nor LG Flash Tool). Yesterday I fixed it by following this guide:
http://forum.xda-developers.com/showthread.php?t=2785089
In particular the part where you change your device to COM41 in the device manager.
After you get it discovered by LG Flash Tool flash an official KDZ.
Reboot the phone and connect it to your Windows, allow the connection from the phone screen.
It should promt you to install drivers on the computer, do that (they are different from LG Drivers you download from the web mind you)
Now you can change your COM port back to 3 and everything should be fully discoverable by both LGUP and LG Flash Tool.

I think I replied to you on reddit (same photo) Have you tried plugging the phone in while in download mode ? Did you try installing drivers from the internet ? Coz thats how I fixed the same problem you have.

Exactly, here I am running around in circles over this BOOST Stylo 2, just got it with MM 6.0.1 out of the box 2 days ago. I caught the 454.4mb update it has been trying to do! Got that baby downloaded! 1.02gb unzipped and renamed to kdz. Got a script for Terminal that will replace Kingroot's temp root with SuperSU but I am not going to attempt any further until I know LGUP will recognize and flash my .zip the bas****s deem not worth enough to put up for download on LG's site!
I got LGUP to recognize it in download mode, reads out LGLS775 but still says it cannot open it...............
His info on how he got it to work would prolly have solved this dillema..............

ok had a LG G3 that's done this- as long as you can get download mode it should recover, YOU need to use the LG mobile support tool from LG website ( LG UP sees phone as unknown model ) run LG mobile Support tool and in option choose UPGRADE RECOVERY . follow instructions and allow to start process, it took 57 minutes to repair my phone - it will seem frozen anywhere from 0% to about 22% JUST WAIT IT OUT!! lg up / twrp flashes in 5 to 10 mins -- the LG m.s.t writes block by block and takes 1 hour +
so hints and info took 3 goes to find and start upgrade recovery - error on a couple of attempts. phone seems frozen around 10% and 15% of firmware upload -- go make a coffee drink it, go pee then come back and worry! A watched pot never boils!....

It didn't. It's EVEN MORE broken :'(

I figured out how to get my PC to recognize my D851. Apparently all the LG software didn't like how many COM ports I have. As soon as I unplugged everything else from my PC, the software worked. In this case, it was LG Flash Tool 2014, but I couldn't get any of them to work before.

Try running LGUP as Admin!!! For me it worked!

Hope someone can help me. I flashed a rom for a d855, d855g30 I think, and although I can access download mode all aps for flashing fail saying it's the wrong model number. Even the generic DLL file cant trick it. It still starts booting the rom but boot loops before entering. I no longer have twrp and when I try to do safe mode or factory reset I get a boot validation error or something similar. Just seem to be stuck. Im using a VS985.

One cause of LGUP "UNKNOWN"
While an old thread, it'll be found in searches. For anybody who gets "UNKNOWN" device with LGUP for the LG G3, I found that LGUP for the G3 is often distributed with the wrong DLL file. See the details here, post #11. After installing LGUP, make sure that the "model" subdirectory in the LGUP program directory is the same number as the processor in your phone, in my case c:\Program Files (x86)\LG Electronics\LGUP\model\8974 (was 8994 with the "LGUP for G3" I downloaded).
