[Q] HTC one M7 in qualcom download mode

I did something silly and now my phone is in Qualcom dowoad mode.
I believe this is called a hard brick.
I believe I can flash firmware using the QPST tool ... does anybody have any images in hex that can be used in the tool?
Thanks
Carl.

No. You need JTAG ..

Do you know this for a FACT (experience) or are you speaking with read knowledge from the forum?
I don't mean to offend you BUT it has to be possible to rip the images required from the phone itself.

Qualcomm is used in lot of newer Samsung HTC and other devices. Look up any other device to find your answer.

I did look around the other forums, it seems to me that it can be done. It hasn't yet been done, that doesn't mean it can't.
I posted here to see if somebody had the images.

Are you s-off? I don't think qpst will help if s-on, although I see an SB3.0 tab in latest qpst which may be of interest.
Here is latest QPST (2.7.402) I could find: http://forum.xda-developers.com/showthread.php?t=2020275
I would like to figure this out as well. I suspect it must be possible, since I don't think HTC would have planned to open the One for JTAG.
Here is some info on the xml formatting: http://forum.xda-developers.com/showthread.php?t=2208289
Still need to figure out which data/partitions to extract from healthy htc one to create mbn files (bin files).
Here is a thread with some qpst discussion related to htc one: http://forum.xda-developers.com/showthread.php?t=2467960

Research...
I've been researching... If there's a dev who already knows this stuff and can help out, would be much appreciated.
Here are my findings so far:

Been reading a few things about unbricking S3 and qualcomm based devices.. Some interesting read here: http://forum.xda-developers.com/showthread.php?t=2345860
HTC One Bootloader: http://forum.xda-developers.com/showthread.php?p=45402164#post45402164

These are just morsels of information I have collected but in theory: If you can get a working Hboot (or ENG Hboot?) on an sdcard and get the phone to read it your phone should boot back up. Assuming your device was S-OFF before any of this happened.
Let me know if any of this makes sense..

How to unbrick hard bricked MOTO G 2nd Gen (xt1068)

My phone is totally bricked not even opening in bootloader. It's only recognized by pc as "qhsusb_bulk". so I signed my phone with "Riff BOX JTAG drivers Driver Signature Enforcement Overrider". after this my phone is recognized as "Qualcomm HS-USB QLoader 9008" under Ports (COM & LPT). Then I extract Motorola qboot utility and then run blank-flash.bat file after that this is showing (flashing singleimageFAILED (blank-flash:sdl-transfer-image:sdl-hello:error sending packet).
maybe that singleimage.bin file is problematic.
So I need correct blank-flash file for my phone.
Help me guys. thanks in advance.

Well, there is a good chance that you can't do anything about it. But, give as some info about what you did to it, what was the last version of Android or Rom on it, and so on.

This won't work, ^^ the "blank flash" in the tutorial you've sent us, is only for the Moto G 1st gen, i've already tried it ^^ this is not compatible :/
This is why we need the blank flash for the Moto G 2014, then this tuto will work ^^

@Andy K
Found the reason why it didn't work. That is because that method is used to rescue Qualcomm Snapdragon devices. Our device is Qualcomm based so yeah. Here's a kinda detailed explanation
Owners of Qualcomm based LG’s, HTC’s, Samsung’s, Sony’s and Motorola’s, im afraid this tool is not suitable for you, because those liers mostly have chosen not to use default options of this platform, they dont (cant) want us to rescue our phones so easly, what would have happened to their service centers all around the world then ? They need to change “The Motherboard” in spite of the ability to fix this problem so easly to earn more and more and more money.

I was on stock Marshmallow 6.0 rom. Then I flashed stock Lollipop 5.0.2 rom in my phone and then I was updating my phone to new stagefright patch but after switch off my phone didn't turn on again.

My last android version was Marshmallow 6.0. I downgraded my phone to Lollipop 5.0.2 and tried to update latest stagefright patch from system update. But after switched off my phone never turn on again. Whenever I connect my phone to the charger it's shows nothing but white led light for 10 seconds. And my phone recognised by my PC as "qshusb_bulk".

Need Moto G 2nd Gen "blankflash image" to flash new bootloader.
As the bootloader of my phone has been collapsed so I need to flash a new bootloader to my phone to relive. But I don't have the right file. And I don't think there is any blankflash image of my phone (XT1068) is available on the net. So I just need to know that is there any way to extract these file from Stock ROM?

No there is no way. I think they already got 5.0 singleimage, but the problem is with programmer.mbn. Without motorola signature it won't flash the bootloader..

still no hope...

Do you have 5.0 or 6.0 singleimage file?

am stuck in the same position. the company has to come up with the new bootloader file. or upload the xt1068 bootloader. one method is throught riff jtag . but very few repair guys have that box. in mumbai they charge 1000-1500rs to repair such phones

Sry, but I only have this file for the D290n.
You can create this file by executing the command above in a terminal app (root required).
If you don't have access to your device, you have to ask if someone creates a debrick file for you.

My D290n don't show anything. Only black screen. When i put on usb then show qualcomm 9008.
No download mode, no battery charge.
Is this helpful procedure to unbrick?

N950U hardbrick...help

HI, I bricked my N950u after rooting with the SamV2 method for snapdragon. I rooted it fine, then tried flashing stock firmware and supersu zip. I know snapdragon is bl locked but I thought I could possibly do something besides hard brick lol. Anyway, does a rooted n950u that they could share a partial or full sys dump with me so I can make a debrick img. Also if anyone knows how to un/debrick please let me know and share. Thanks in advance!!!!
P.s. I know it was stupid to do lol
p.p.s. if your not going to contribute to the solution and or insult my foolish decision please keep your comments to yourself, thanks

You cannot debrick. What does your phone do?
EDIT: you probably are not bricked anyway. Actually you might be bricked if you flashed stock rev1 firmware instead. That would brick you...

Yup. Thats 100% a hardbrick. Unfortunatly the debrick img method doesnt work on this phone. Only way to fix at this moment is a carrier swap. Thats how I got mine fixed.

Carrier swap? can you explain a bit more? But I believe if I had a system dump for the note 8 I can make a un/debrick image just like previous Samsung devices. I'm willing to try but i dont have the software needed

Long shot but... qfil / firehose msm8998 is the way to go with this. Can be done, the hard part is getting the firehose programmer (and maybe rawprogram0 / patch0 xmls too)
Isnt it supported by Z3x / Sigma / Infinity / Octoplus?
Doesnt that "aryk" site have a load of programmer files that could work with your device?
Failing that, JTAG / EMMC flash (pinouts should be around somewhere)
Sorry can`t be more help. I`m working on a similar issue with a Moto Z2 play atm
EDIT: I`m sure the 835 (what you have) supports booting from the SD card.
You need to ask someone with a rooted Snapdragon N8 to make a copy of the first 167(ish) MB of mmcblk0
Like this... (Brief idea... whoever does this needs to do it obviously from shell, on the device itself wether thats from TWRP shell or ADB in *nix / Win thats up to you)
Code:
dd if=/dev/block/mmcblk0 of=/sdcard/Loader.img bs=1024 count=168960
Once some kind soul has done this for you and you have downloaded it, write the resulting image to decent SD card using Win32diskimager, place in device and try booting. See if the bootloader runs enough to get you into ODIN.
YMMV but it is a recovery method for Snapdragons. Weather you overwrite EFS / Lose IMEI I don`t know. Only just getting back into Sammy scene.
It is kind of like a failsafe incase of EMMC corruption I think.
I can`t help with this sadly as I`m Exy

MDM error, tablet T713 stuck on bootloop.

Hello everyone,
I have my tablet SM-T713 which finds itself completely blocked following a dumpling on my part:
I had activated a software which prevented the installation of software etc on the tab and wanting to simply reset, I had the ingenious idea of ​​making a Wipe data and attempted an installation of a full firmware via Odin above .
Fatal error ! Unable to write on it (MDM) and I find myself in bootloop without the possibility of writing on it or anything.
I tried the TWRP flash without success, I cannot try in ADB or SD : refused.
Is there a tiny hope or can I use it freezbie?
Thank you really much by advance.
Jonathan

Well I don't know how to build it (yet?) but as I'm interested to know as well, I've asked for how-to on that specific page.
Downloaded a stock T713 ROM and unpacked it.
It contains .mbn files but no .edf I can't identify all what the .mbn are for, if these would be sufficient or more/others are needed.
And of course don't know if the found ones could usefully be flashed with the QPST.
Hope the guy from that page will give positive answers.

The guy wrote an answer but not helpful at all:
<Hi. In case of Samsung devices, the only thing that will work is the Odin program. It’s hard to see a Samsung device getting hard bricked, just because Samsung has all those critical partitions blocked from being flashed. If you ever come across a soft-brick, you can just use Frija to download the latest Odin-flashable firmware and push it through Odin.>
So sorry.
