D620r bricked (Qualcomm HS-USB QDLoader 9008) - LG G2 Mini

Hello,
I have an LG G2 Mini (D620r) that shows no signs of life(won't turn on, indicate charging etc.). When connected to a PC it appears as "Qualcomm HS-USB QDLoader 9008" under windows and as "Gobi Wireless Modem (QDL mode)" under linux. I've found a kdz (D620r20b_00.kdz) and have been tried to extract/flash/use it, but I don't have much experience fixing bricked phones(none). BoardDialog gives me some weird "Out of memory" error(image.prntscr.com /image/RWFfhRuRTG_EYYm9bOzpqQ.jpeg). Am I doing this the wrong way? What tools should I use to fix this?
Thank you in advance for any help!
George.

I discharged the battery to 3v. Nothing happened when connecting it to the computer...

This should be the same mode you have, so no need to short the pins:

I followed the guide and get some error(0x80004005) along the process.

No idea what that error is.
Try to see if you can find it on Google.

Disable antivirus.

Disabling Windows Defender didn't affect anything. Is the error somehow permission related? Do you know what it means?

"This problem may occur if a file that the Windows Product Activation (WPA) requires is damaged or missing. This behavior occurs if one or both of the following conditions are true:
A third-party backup utility or an antivirus program interferes with the installation of Windows XP.
A file that WPA requires is manually modified. "
This is what it says on the microsoft website for installation of Windows XP. I'm guessing it's the same for this installation too.

But that is a windows error. Not a QPST error(?).

It was the only sensible thing I found for that error code, so I suggested it anyways, nothing to lose

[SOLVED ]I bricked my phone, help me :'(

I was installing root to my cell phone, the installation everything fine, but when I was installing the original recovery, I accidentally moved the USB cable and it was disconnected, it stayed in the red bar of the flash tool, I gave it in "stop" and try to do it again, now the sp flash tool does not recognize it, but windows recognize the device as "Mediatek DA USB VCOM (Android) (COMX)" where X is a number.
I've read through other topics that keep the Vol+ works, but it does not work with me, or I do not know if I'm doing it right.
I have not removed the battery because I do not know how to open the cell phone.
In the sh flash tool, I use: "Download Only"
Sorry for my english.
EDIT:
I open the phone, quit battery, put again, and sp flash tool detect the device again

How did you manage to open the phone? When I tried it it felt like something was going to break.

Android (LG G6) won't connect as MTP to Macos (as ADB it does)

Hello everyone,
a) My guess is, it might a problem with the drivers. I installed some LG programes earlier, already deinstalled it... But, Maybe you know better how to renew the Android drivers on the Mac and get rid off the stuff which probably blocks me from having the file transfer function again.
b) do you know at least any other (free) Programe that uses ADB to connect the phone to Mac?
c) something I have not thought of... You tell me
Once it was possible to connect the phone to my Mac and transfer files with Android File Transfer. Now it is not. I tried several other programmes, none can connect to the phone via MTP (for file transfer).
When I chose not "data transfer" but "photo transfer" as an option in the phone, the Photo app on Mac opens and I could trnasfer photos - so it works!
But I need file transfer....
I have and try several cables. Phone works without any problems with windows.
The only thing works now for transfering files via cable is MacDroid, which can connect the phone via ADB insetad of MTP. --> Problem: it costs money (and why should it now work in MTP in the first place).
The phone generally is found by the computer:

I use as OS "El Capitan". On the phone Android 9.0. Phone LG G6
Thank you!
PS: The phone even asks me if I want the Mac to authorize:

PS2: Macdroid works with the phone even in MTP Mode when Debugging is deactivated. So what is this... I do not get it.
Guys, girls, anybody, please give me a hint, think with me, tell me where to look for answers ...
Finally... I knew it was some ****ty LG Software... I installed all the LG Software I could find on their website. Plus some dirver they provided. And THIS time, I deinstalled them using their own tool. Now it works again...
I think I had installed something earlier and then just deleted it or something.
So in short, it was necessary do install and UNINSTALL the LG drivers from their website.

Hi guys absolutely pulling my hair out with this phone. I just want to USB tether my internet and I'm getting "CDC NCM No driver found" in Windows, and when I check Device Manager it just says Other -> CDC NCM with an exclamation mark. Searching Google has been incredibly useless on this issue. I've never had issues with any other phone like this before. Anyone know how to solve this? Thanks.
What version of windows? Did you try more than one computer or the PDF instructions listed here? https://docs.microsoft.com/en-us/an...m-devices-arenamp39t-assigned-usbncm-dri.html

I haven't tried it on my Windows 10 Home PC but the issue is getting it on Windows 7. I followed these instructions but I don't see USBNcm Host Device in the update drivers list for Windows 7 and I don't know how to get it to appear.
have you tried the google usb driver?
Get the Google USB Driver | Android Studio | Android Developers
The Google USB Driver is required to perform adb debugging on Windows with Google devices.

Install the drivers that nutzfreelance linked. Have to disable driver signature verification on Windows for it to work. Mine were slightly out of date and stopped working on one of the phone updates. You also have to select USB tethering in two places:
Settings -> Network -> Hotspot
Dropdown menu: change "charging via USB" to USB tethering
It's probably been this way since Android 11 maybe? Pretty sure on 10 you didn't have to do step 2. Could be wrong though, haven't needed to tether for a couple of years.

Question Haviing trouble unlocking bootloader

I followed the steps, but I can't get into bootloader mode. Please help. When I reboot to bootloader, the screen is blank and doesn't respond to fast boot commands.
Turn off phone then hold volume up and plug into computer to get to bootloader mode (screen should still be off)
If computer doesnt recognize fastboot mode then your computer is lacking the right driver
I did follow the steps and downloaded both the google USB driver and driver for my device model from sony mobile communications via 'install OEM drivers'. Did I miss anything? In fact, how do I remove and reinstall both drivers if they are faulty?

I remember window 10 and 11 block driver if you install normal through double click. You need to get to device manager and update driver manually. Google it
i tried but still the same problem. From this screenshot , could you make out anything regarding anything ive might have missed. i installed the google usb driver and fastboot driver by the device manager as stated in the previous comment.

Boot windows in safe mode, and disable driver certification and reinstall the driver.

Hey, man I had a problem with the drivers in bootleader mode on my 5 IV as well. Which had the Android under Other Devices with a question mark, meaning it couldn't find the drivers.
You could try forcefully installing the drivers for the device as I explained how to do in my post here: https://forum.xda-developers.com/t/...-and-flashing-firmwares.4537183/post-88051049
Make sure you don't have US version because you can't unlock bootloader on it

There's a Sony driver you jeed to use, SA2000 or some weird name. Did you get that one? Install it by right clicking on the Android device name with yellow warning triangle. Select the install disk manually and assign that one to manually install

Hard/dead bricked mediatek tablet

I need help repairing a bricked Chuwi Hipad X tablet, which is a Mediatek device. The power went out while flashing, and now the tablet does not turn on. I have the stock firmware and scatter file from the brand. I've tried using libusb and bypass_utility, but the latter stops at "disabling watchdog," and Sp flash tool gives me a da_hash_mismatch error, even with only the preloader selected. The device is already insecure, so I'm not using libusb filter and bypass utility anymore. When I manage to get the tablet in BROM mode, the DA download starts but stops after around 7 seconds, giving me a STATUS_DA_HASH_MISMATCH error. I'm not using an auth file, and I'm using MTK_AllInOne_DA.bin as the download agent. It's possible that the preloader is bricked too. If necessary, I'm willing to disassemble the tablet, although I think it will be difficult. Please let me know if you have any suggestions or questions.

As of now I'm trying with MTK Client and I'm getting the same error...
I already give the preloader as an argument when calling the program, and as of now I'm only trying to flash the recover.

Excuse my ignorance but this is only temporary and has to be done each time you power off, isn't it?
If for power off you mean the PC, I delete and reinstall the filter everytime, while if you mean the tablet I don't really have a way to keep it on so I don't know...
You wrote "The device is already insecure" so I assume with "device" you mean the android mediatek device. I am referring to the Mediatek bootrom exploit. this exploit does not unlock anything on your mediatek device permanently, the procedure has to repeated each time you enter brom or preloader mode. Therefore I am not sure what you mean with "already insecure"
It's now easy to bypass MediaTek's SP Flash Tool authentication
A group of developers has created a Python utility to bypass the authentication routine of MediaTek SP Flash Tool. Check it out now!
www.xda-developers.com
Shouldn't mtkclient do that automatically? If I check the output log at a certain point it says "DA Handler - Device is unprotected"...
yes, but your first post is about SP Flash Tool
Oh, my bad then, I changed tools yesterday.
The error is still the same though, even if I flash/don't flash preloader right away.
Any suggestion?
Idk. kamakiri2 obviously failed, try kamakiri? open issue on github? or search for secure boot DA + auth_sv5.auth?
I tried but nothing changed...I managed to dump the brom though, I'll upload it on Drive and put the link here if it helps in some way.
