[Q]Lg Factory Rom On My Quantum?

Looking for the factory rom for my lg c900, as I flashed it to mango but cant restore nodo on it can someone help me out?

Here you go!
There are instructions and download links there.
When I flashed my Quantum, it took me a while to realise that (at the very very end), you need to press 'start' in the LGDP2 utility BEFORE connecting the phone. So watch out for that.

thnx for that, i've seen the thread and downloaded everything, but this step:
"2. Install LG United Modem Driver, connect the phone to PC through USB cable and let the drivers to be installed. USB 1.1 is recommended."
I dont get what to do, after I install the united modem driver, and not sure where or how to get the firmware that it lists in step 3:
3. You'll need firmware in DZ format and the correct DLL for your model.

2: You just download it and plug in your phone. Nothing really happens, but it's necessary because later, when you want to find out which COM port it's plugged into, you'll have to go into Device Manager and, under Modems, you'll find your phone and right-clicking it and selecting proprieties.
3: The DZ Firmware is the first file you downloaded (it's under FIRMWARES on the page I linked). You have to choose the right one for your phone (by carrier) and unpack the contents. In there, you'll find a .DZ file.
A link to the DLL files is also provided (the word DLL in that step is the link). Again, download the right one (the one with the letter at the end of C900 that corresponds with the Firmware you downloaded - nothing (US), C (Canada) or K (Australia or NZ).
If you have any more problems with the instructions, just ask. We'll keep them on this thread in case anyone else needs help with this in the future.

wow I cant believe I missed those links lol thnx alot, i got the dll and am downlading the DZ now, and ill let you know if i have any problems

Okay so I dl'ed the DZ file, but when i open the lgdp32 exe and select umts division, it gives me a fail to open dll file, and then has a ports selection screen with com 7 selected. And com 7 as IDLE.

BTW this is with my phone unplugged, I noticed that nothing happened, and in device manager it just said drivers werent installed,but in emergency download mode it installs all drivers through the found new hardware wizard.
And got this during the installation:

though I'm not sure how to resolve that last issue, I do know how to fix the idle problem: ignore it. It took me forever to realize that: just press ok and then, in the main window, press start. Then connect the phone.
Also, are you sure that it's connected into port 7? Did you check in the device manager?

well the first time i plugged in the phone i was able to check and it said port 0, but I dont see that, but now that its giving me this INF message, when i click properties now the device manager just stops responding for some reason.
EDIT:when i have the phone plugged in normally, not emergency download, it says this:
Location 0 (USB Device)
for the port, but i dont see a com 0 option?

Oddly enough, my phone is now saying theres an update available, but it doesnt sync with the zune software for some reason.
EDIT:just got the installation fixed, and this is the modem page for the device manager.
I did everthing you told me, and found the com port(it was com 3), but when i hit start and plug in the phone in emergency download mode, nothing happens for some reason.

Are you sure that you're using the LGDP2_V36?
You said V32 earlier and I just noticed it. If that's the programme you've been using, try it with the V36 in its stead.

yeah I've been using the 36 one, sorry about misposting not sure what to do now though.
Could the error message "cant find monitor port" have anything to do with this?

Ok, so Today I had to flash my device anyway, so I went through the steps to get more insight into your problems.
What I learned is that you have to ignore all the problems.
So, once you've installed the LG drivers, plug the phone in in Emergency Download Mode and let the computer do whatever it needs to. If there's an error, that's fine. Next step.
Start the LGDP2_V36 UMTS and ignore any problem you're given once you've chosen the option UMTS.
In the bigger window that pops up, click ALL to select all the ports. It saves you the trouble of trying to find the port number of your Quantum.
Find the DLL and run the 'Download Configuration' and find the DZ Firmware. Press ok.
The 'Can't Find Monitor Port' doesn't mean anything. Press OK and continue.
Click Start first then plug in your phone in Emergency Download Mode.
Try this, then get back to me. I'll be checking the forum every 10-or-so minutes to help you resolve your problem as fast as possible.

okay im starting right now, ill just keep updating this post through out.
Update:installed drivers correctly with phone plugged in, unplugged it and started up LGDP2_V36 UMTS, then picked all com ports, found the dll and selected the dz file, hit ok, ignored the cant find monitor port, hit start, then plugged in the phone again in emergency download mode, but when i plug it in, all the ports still read idle, and then the found new hardware wizard still pops up even though i already installed it, then it gives me that INF error. The program is still running and the phone is still plugged in. What do i do from here?
Update:Just noticed that the LG united modem driver says Win7 in the folder name, Do I have to have windows 7? cause Im running XP SP3. and also theres two installation packages, am i supposed to install them both?

Sorry for the delay...
I'm not certain... I have Windows 7 on my PC. I'll do some searching and get back to you.

Here, try this Driver and give me news on how it worked.
Link!

I downloaded the driver detective setup thing, but its asking for a registration code, and I dont have $25 to spend

Ah. Let's try something cheaper.
Update: How about this?

the drivers installed fine, but its still doing the same thing, after i get past the port selection and hit start, when i plug in my phone, all the tiles still read idle, but now the device manager doesnt crash when i select properties for it, and it still says its in COM3. also on the ports selection, am i supposed to check off usb mode?

USB is not supposed to be checked.

okay, its still doing the same thing. I really appreciate all the help with this BTW

Call from Windows using Android phone

Background
Back in the day when every computer connecting to the internet was using a modem and dial-up link, you could also use the modem to dial from your computer to any phone number using dialer.exe. This was great because you didn't have to leave your keyboard and could use your pc speakers and microphone to make a call. This made me wondering if it would be possible to use my mobile phone (in my case the Samsung Galaxy Note II) to act as a modem to make phone calls. I have looked over some forums and managed to get this working. Since it took me a while, I made this thread so other people can replicate.
Before we begin
These steps were successful using:
Samsung Galaxy Note II (Android version: 4.4.2) and Windows 7 (64-bit)
Steps
Connect phone to pc as a modem
Install phone as a modem in Windows
Make a phone call
Step 1: Connect phone to pc as a modem
Enable Developer Options menu
On your phone go to "Settings", "More", "About phone".
Locate "Build number" and tab it a few times. You will get a notification that the Developer Options menu is enabled.
Enable USB debugging
On your phone go to "Settings", "More", "Developer Options"
Locate and enable "USB-debugging"
Enable USB to act as a modem
On your phone go to Phone and dial *#7284# (including the asterisk and hash). The Phone Util service mode will appear.
Under "USB" select "MODEM" and press "SAVE and RESET". Your phone will now reset.
Connect your phone to your pc using an USB cable
If your phone isn't already connected to your pc, now is the time...
Step 2: Install phone as a modem in Windows
I have used this thread to enable the modem under Windows: [REF][XMM] Infineon FlashTool & Comneon 7 CDCs Driver by E:V:A. This might also be helpful to install the drivers for other phones.
Detecting hardware
When your device has reset and is connected to your pc Windows will detect the new hardware, but will probably not find any drivers. There will be 7 CDC's listed as new hardware and one Comneon USB device.
Download drivers
The drivers for the Comneon modem can be found here: DRIVERS___WMC_comneon_3.33.0.exe - 694.68 KB
Or for the brave the direct download link: http://fs1.d-h.st/download/00111/55i/DRIVERS___WMC_comneon_3.33.0.exe
Install drivers
Install the drivers using administrative privileges. After installation the modem should be found and installed correctly. The following devices should be listed in Device Manager
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 3: Make a phone call
Phone and modem
In Windows go to Control Panel and search for "modem". Click on "Phone and Modem". If you haven't set a location before, add one now.
Go to tab "Modems", your device's modem should be located here. Select it and click "Properties". Go to the tab "Diagnostics" and click "Query Modem" if you get a response (e.g. not a blank response) your device's modem is correctly installed. Close all windows.
Phone Dialer
Press Start, Run (or Windows key + R) and start dialer.exe, located in the system32 directory: %windir%\system32\dialer.exe.
In Phone Dialer go to the "Tools" menu and select "Connect using".
Under "Line" select the modem we just installed. Click "Line Properties" and set the "Port speed" to "115200" (this step is not really required).
Now we are ready to make a call. Type in any Phone Number and the Phone Dialer will start the call. The "Call Status" will pop-up. Do not press any of the buttons unless you want to hang up.
Tips & Tricks
You still have to use the phone's speaker and mic to actually communicate. To use the computer's speakers and microphone I use a bluetooth dongle to let the computer act as a bluetooth headset for my phone. Not every bluetooth dongle is capable of this feature, you need one with a headset profile (HSP). The Konig Micro Bluetooth USB 4.0 Dongle has this profile and I use it to turn my pc into a headset.
You can also make calls from Windows using Outlook. Go to "Contacts" and right click any contact and select "Call". You can also make a phone call to any number by selecting "Call" under "More" in the ribbon of "Contacts".
Using Hyper Terminal it is also possible to receive incoming phone calls. You can connect to the COM port that is used by the modem (the used COM port is located in the properties of the modem). When connected to the COM port you can answer a call by typing the command ATA followed by Enter.
Final words
Any comments are greatly appreciated, since this is my first ever post. Also if you have similar successful implementations, feel free to comment so I can add these to the list. Thank you for reading and special thanks to E:V:A for submitting his useful post on where to find the modem drivers.

Great job... but it would have been easier to use speaker phone mode on the phone

Use MyPhoneExplorer...
You can call, sms, install apps, access data, call logs any many more...
No need to do any setting, just keep USB Debugging On....
You can even connect mobile wireless also thru wifi...

Nice work OP!
Another easy way to do this is to install MightyText. But then you're entrusting all your data to a third party.

Nice trick but a difficult one.

Did you ever ask yourself the question ... "But Why?"

[UNBRICK] Unbrick Tutorial For The OnePlus 3T!!!!!!!!! by Haris K.

Hey Guys!!!
Many people who own the new OnePlus3T and try to install root or TWRP etc. will often get errors.
In my Case it was so that I could not go back on my TWRP backup. Unfortunately there was at that time no OnePlus3T Rom, so I tried to install from the original page the OnePlus3 Rom. finally came out -> My OPT3 was bricked....
A hard brick is very hard to fix at the moment, because the tools etc. are still outdated and currently run only for the OP3 and not for the T model. That's why I took the trouble and sometimes put the files together. Now I have also managed to unbrick my OP3T.
So, I'm a nice guy and I publish my Files for fixing the OnePlus3T.
For the on Plus 3:
Step 1: Download Driver and Unbricktool
1) Driver: https://mega.nz/#!AgohmbqC!h16GeeOnlvubYDyfID3feY-qVJuBZiWVvYsXSAeKIA8
2) Unbricktool(OP3T): https://mega.nz/#!Q1YnTTAT!gnLf6NEkSRy7W-WY8J0H2SmJJLzO91-vReKx7B1VVpI
Step 1: Extract Drivers and Recovery Tool files on Desktop.
Step 2: If you are using Windows other than Windows XP,turn off Driver Signature Enforcement.To do so,follow this guide :
http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/
Step 3: Press the power button for 40 seconds to turn off the phone.
Step 4: Press the volume up button for 10 seconds, while connecting the device with the computer.
Step 5: Open your device-manager and make sure in "Unknown devices" is one device with the name "QHUSB_BULK".
Step 6: Right Click on your device in the device manager and select Update Device Software. Choose manually the drivers folder and install the driver.
Step 7: When the device shows as "Qualcomm 9008", go run the MSM Download Tool as administrator.
Step 8: Click start at top left corner and wait for it to finish (green text will come).
Step 9: Disconnect phone from PC and boot into system.
Welcome back in life OP3T!!!
There you are! Don't forget to thank!
EDIT: Sorry for my bad english!

Time to try this tool. I have lost a lot of space on my 128GB 3T as you can see.

Uh, try to disconnect your device and turn it on. If its blackscreen only, try to charge it with the original cable. If it shows no reaction. Try to install the drivers again and run the tool again in administrator mode.
:good:

Blackscreen after i try to turn it on. No yellow light. No response on charging. Pressing volume up and connecting cable in testmode on windows but no response in device manager.
It´s there though.

Reinstall the driver from the device. Hold the Powerbutton for like 40 sec. after it, connect it to your computer and open device manager, it should show as Unknown Device....

Hello everyone !
I have a Chinese Head Unit (Motherboard Marking: YT9260-ver0.2, Model no: 8227L_demo android 9.1, Android: YT9250_AHD_00006_V004_20190610_DSP, Kernel: 3.18.22, DDR 2GB FLASH 16GB, Mediatek MT6323LGA, Foresee FSEIAD9D EMMC 16G). Unfortunetly bad rom and preloader was written to the device and now it is completly brick. When i connect to USB my computer detects it (Mediatek USB VCOM), so maybe i can save it. Can anyone send me a preloader with scatter, rom and memory dump? Could someone please give me some ideas or advice? I also attach some pictures. Best wishes, thank you.

Disconnect the USB
Repeat steps 1 - 6, then continue to 12
Press Ctrl+Alt+V , then go to Window and select "write memory".
In file path select your backups (EMMC_BOOT1.bin, EMMC_BOOT2.bin, & EMMC_USER.bin), in begin address put 0x0, in region select the correct partition to match the backup. Hit Write memory. Repeat this step 3 times, once for each region (EMMC_BOOT1, EMMC_BOOT2, & EMMC_USER)
Short the two test points (see picture) without power and then plug in the usb cable (connected to usb1 port).
Remove the short when process starts.
Your backups are restored

I tried this method. My computer recognizes the device on COM3 port, in program the red progress 100% (Download DA 100%), then after 10 seconds the program prints Enable DRAM failed. I followed you instructions step by step, I shorted the two test points, but the program just prints Enable DRAM failed. Any idea ?

I have no memory dump. I got the device after they had uploaded faulty rom and preloader and they didn't make a backup. I know that if the preloader gets damaged, the usb connection will not be established, but in this case it will be up because my computer recognizes the device. There may be a problem with the preloader being defective and the Flash tool cannot write to the memory. Can we write through Rx Tx? It is possible ?

I got the same head unit with the same problem. Ill try this method and see what will happen

This is a bit old thread so I'm not too sure if it still useful, but if so I would recommend to use Arduino Uno which can easily communicate through UART.

Short the two test points (see picture) without power and then plug in the usb cable (connected to usb1 port).
