Unbricking LG LU6200

DISCLAIMER: Not my work, Tutorial followed from : http://choimobile.vn/threads/unbrick-lg-lu6200-ghim-cap-qhsusb-khong-thao-may.8448.html
Hi
I have been using LU6200 from last one year, and I loved this phone. I have tested many roms, and was using 4.4.2 CM11 rom. Then I installed an app from Play store, which modified the kernel, and booted my phone.
At this stage, my phone was totally dead, no screen indication, no light, no sound. Only one thing, is that when I connect my USB cable to computer, my computer try to install driver and also make sound of USB connection and disconnection.
So below are he steps which I have performed
MUST: KEEP YOUR PHONE ATTACHED WITH USB CABLE TO PC

Winhex - Forensic or Specialist version full not evaluation and registered. I have found only one version [WinHex 17.SR1.rar] which worked for me, not remember where from I downloaded this
Follow this tutorial http://www.howtogeek.com/167723/how...8.1-so-that-you-can-install-unsigned-drivers/ to run your OS in Advance mood where we have to disable DRIVER SIGNATURE ENFORCEMENT
When you have booted into windows after disabling driver signature, install the 1st Link file,
Install the Driver, when Installed it will show a COM Port installed, QUALCOMM one
Install the Softwares, default path will be C:\Program Files (x86)\Qualcomm\QPST\bin\
You also have items in your start menu, so run
1, In the "Start Menu" -> "QPST" -> "QPST Configuration" RUN This
2, Select the tab "PORT" and click "Add New Port ..."
3. A new window will open where the COM port which is newlly added to your system will be listed, select that port and add that
{
"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_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Keep that running
4 Go to the "Start Menu" -> "QPST" -> eMMC Software Downloadapp " RUN THIS
4.1 Uncheck, Program MMC Device
4.2 Click Browse, it displayed me PHONE ATTACHED with QUALCOM details near the top right of the image, where No ports Active is written
4.3 Check Search Path 2 and Browse to you files, where you have downloaded 3rd file. Which contains one hex, one img and mbn file
4.4 In the Flash Programming File name, enter the name of hex file
4.5 in boot image, enter the mbn file name
4.6 Click DOWNLOAD
at this point, it mounted me a 200kb drive which was not formatted. I have formatted that, and then kept this program running in the background as well
5. Winhex
5.1 Run Winhex, Make sure you have forensic version, and also Full version ,there are evolution version too, but that will not work. FULL VERSION and FORENSIC/SPECIALIST License is must
5.2 In Winhex, go to "File", "Restore Image", Change the file type from "WHX" to "Raw Image container"
5.5 Select lu6200.img from the 3rd file downloaded
5.5 Now it will ask for Target disc
5.6 Carefully select the QUALCOM, or else you will be formating your own HDD
5.7 In this window click OK
Now it will start giving your some strange, nasty warnings, just keep pressing OK, and Yes Continue Ok, etc etc
When that will finish, you phone will auto restart.
Now you may have to reflash that, or wipe it and install the KDZ ICS engineer version again. As right now My phone is in boot loop but I guess that can be fixed.

[HOW TO]Backup Windows 10M System Image

Hello everyone,
As per the title says, I will let you know how to backup or get your Windows 10 Mobile system image. This might be helpful for those who own an unsupported phone and want to try new builds of Windows 10M.
Since at some point Microsoft will shift RS builds to Release Preview ring and currently unsupported devices can only get 10586 builds which are only available on Release Preview ring. And to get RS builds with registry trick we need to be on 10586 and sometimes due to problems we need to get back to 8.1.
So, 10586 builds are going to be replaced soon and at some critical situation we need to go back to 8.1 then we will get stuck with 8.1.
With this guide I will help you to get a copy of your Windows 10 Mobile backed up for those situation, so there won't be any need to switch back to 8.1. You can directly restore the backed up version. The backup will work as a custom ROM, so you need have your phone's bootloader unlocked to flash it.
Points to note:
-With the backup, you will be able to backup all your installed Apps and your Data (Photos, Videos...etc.).
-Backup is OS version independent, the only thing which matters is the availability of latest firmware of your phone.
Tools you need:
- Windows Device Recovery Tool
- Windows Phone Internals
- Lumia Emergency Flash Loaders (Attached one for Lumia 820, 920, 920T, 925, 1020)
For other devices you can follow this.
- Engineering SBL3s (Attached one for Lumia 520, 620, 625, 810, 820, 822, 920, 925 and 1020)
For other devices search it on Google, you may find one.
Lets start
Preparing your phone for the backup
1. First of all make sure your phone is listed in supported list of Windows Phone Internals. if yes then continue.
2. Switch back to 8.1 using Windows Device Recovery Tool.
This will download latest available firmware for your phone on the server. Once done, on your phone go to Setting > about and write the firmware version number (You may need it later.). Also don't forget to disable Store auto update to avoid Extras+Info update.
3. Before jumping to Insider Program, check for update on your phone and install all available updates (if available.)
If updates were available, probably your firmware version has also changed, because not all updates from Windows Update servers are moved to Windows Device Recovery servers.
The firmware version number is consist of 4 parts (separated by "."). If the difference between the one you installed using Windows Device Recovery Tool and the one via Windows Update is only in 2 last parts, then it won't be a big problem. Like this:
{
"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_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
For most devices there aren't any major new firmware updates available, except those which came with Windows 10.
4. Now, you need to unlock your phones bootloader and enable Mass Storage mode. To do this you need to have Engineering SBL3 and Emergency Flash Loader for your phone. I have attached for some phones.
a). Connect your phone to PC.
b). Open Windows Phone Internals and select "Unlock bootloader" and click Ok.
This will switch your phone to Flash Mode.
c). Now, in next window you have to select .ffu image of your phone, Emergency Flash Loader and Engineering SBL3.
The .ffu image for your phone was downloaded via Windows Device Recovery Tool and the path for the downloaded one is:
C:\ProgramData\Microsoft\Packages\Products Here you can find a folder RM-xxxx (for your device). Inside the folder there is only one item with .ffu extension and you need to use that in Windows Phone Internals.
Also select proper Engineering SBL3 and Emergency Flash Loader for your device and click "Continue". Give it some time and your phone is boot loader unlocked and Mass Storage mode enabled.
A complete guide for this is also available on Windows Phone Internal - Getting started section too
5. Install Windows Insider and get the latest Release Preview (10586) update.
After getting latest Windows 10 update, I prefer to do a hard reset and continue to the backup part.
Now your phone is ready for the backup.
You have the choice whether you want to install all your Apps and then do backup (to keep your Apps backed up too) or you only want to back up the clean installed Windows 10.
Backup and Restore
1. Connect the phone to PC.
2. Open Windows Phone Internals and click on "Backup" for the left pane.
3. Select a name for your backup file
4. click "Backup phone"
The backup process will take at least an hour (depending on the amount of Apps and Data on your phone)
To restore:
Assume you are on as RS build and some problem occurs, you don't need to switch back to 8.1 to get 10586 build. You only need to restore the backup file you created above.
1. Connect the phone to PC.
2. Open Windows Phone Internal and click on "Flash" from the left pane.
3. Select the source file (the backup file you created above).
4. Click on "Flash custom ROM".
Restore process will also take an hour, be patient.
This was all.
You can use the backup file at anytime you want
Make sure that you aren't getting major firmware update from Windows Update (OTA). If you get one the bootloader will be locked back.
Correct me if anything is wrong above .

If it would be a ROM you might want to share it, am I right? So it is a image of partition including personal data, specific OS settings etc. as described by author long time ago....

Right, it is an image of partitions. I used ROM word to make it a bit understandable for all.
P.S: Edited the title, maybe that fits best.

Hi,
This method does not require any SD card, you only need to check if your phone is in the supported list of the Windows Phone Internals tools. Lumia 930 is not yet in that list.

Actually use WPInternals is not good
You can try use thor2 backup to save your disk space

[GUIDE][BR][LP]Complete guide for unlock bootloader and flash TWRP in H442F DUAL SIM

Hello folks!
It's been a while since last time I spent in this forum section (when the method for flashing Poland MM KDZ was published), but suddenly I decided to check the current development and it was great do discover that developers found a way to unlock bootloader! Then, I tried to do the procedures, found some adversities around the path, flashed stock KDZ for my device A LOT and finally managed to obtain a fully working LP stock with root and TWRP for my model: H442F (Dual SIM) ("LG Volt 4G" in Brazil).
The thing is: although a lot was done regarding the Spirit LTE, I found near zero information specifically for my device variant. Since I tried a lot of paths and eventually achieved an interesting result, I decided to write a full tutorial, with a lot of instructions and pictures for "novices" who desire learn all the steps but gives up at the high learning curve. Finally, I also wrote this tutorial in Brazilian Portuguese, which I believe will help at least some comrades (you can download the PDF in portuguese HERE).
Needed files:
LG Drivers (remove old ones if already instaled)
LG Flash Tool 2014 (credits to @quangnhut123 from this thread)
Brazilian H442F10a Firmware (this is a low speed server, I can upload to a better one if someone asks)
Android SDK Tools (for Windows users; Linux ones just install the package android-tools-adb)
Kingroot (or download here: www.kingroot.net)
Latin America Patched Aboot (credits to @pvineeth97 , for more info check this thread)
TWRP (or download here: https://twrp.me/lg/lgspiritlte.html)
Flashfy (or download here: https://play.google.com/store/apps/details?id=com.cgollner.flashify&hl=en)
SuperSU (or download here: http://www.supersu.com/)
Finally, if you prefer, you can download a full pack in this link (except for KDZ), however, I did prefer to keep isolated links for better credits and referrals
Step-by-step
Download all needed files
Install drivers, SDK and unpack Flash Tool
Save all files in the same folder, but keep KDZ file inside Flash Tool folder
Put your phone in download mode (power off, hold vol+, plug usb in pc, keep holding until download icon appears)
Wait a little for Windows completely detects device and load all drivers
Verify in Device Manager if your pc detects phone as "LG Mobile USB Serial Port (COM#)"

}
Open LG Flash Tool as admin
Select KDZ file
Choose the downloaded H442F10a_03.kdz file
Choose CSE Flash
Click START
Then, "Clear phone software update registry"
You'll see a warning
Then, OK (no need to change country)
Another app will open for the flashing. If you are offline, it is possible to show just a "?" character. Wait patiently...
In about 5min it will finish
After some reboots, you'll see the phone starter screen. Just move forward (no need to configure anything right now, maybe wifi, but not google account)
Enable Developer Options going to Settings/General/Common/Software Information and tap some simes in Build Number until the "You are a developer" message appears
Go back to Settings/Developer Options and turn on USB Debugging
With Debugging on, choose MTP (for Windows) or PTP (Linux), and when asked, allow the computer
Now, make sure you installed (and know how to use, since I will cover just a few commands here) the Android Debugging Bridge (adb). It will be essential for some steps, as well for entering Recovery Mode (I will show some Linux screenshots because I do not use Windows - for this tutorial, just for KDZ flash - but with a working adb the commands are the same)
Open a command prompt (Windows: right click in start menu) or a terminal (Linux) and run "adb devices" to see if the device was detected. If not, run again and check if phone are asking permissions (and grant it)
Go (cd) to the folder with all downloaded files and write the commands (some names may be different if you downloaded individual files from official links)
adb push aboot_5120_patched.bin /sdcard/
adb push twrp-3.2.1.0-cn70n.img /sdcard/
adb push SuperSU-v2.82-201705271722.zip /sdcard/
adb install Flashify_1.9.2.apk
adb install KingrootV5.3.1.apk
At whit point, make sure your internet is fully working (3-4G or WIfi), then, open Kingroot and root the device
After a well successful root, go back to adb and run "adb shell" and then "su". The phone will ask root permission. Grant it and in adb again run "cd /sdcard"
Now we arrived a critical step. Make sure to type the command as is show, because an error may result brick. We will copy the modified aboot into the respective phone partition (check code, check picture, and double check!)
If everything occurs all right, will appear this message
Great! Now you have an unlocked bootloader! What we have to do now is fhash a custom recovery (in this case, TWRP).
Open Flashify, give root rights, then go into Flash/Recovery Image/Choose a file/File explorer/sdcard/[downloaded file]. When asked to flash click "YUP!" and then "Flash More" (as we do not want the phone to reboot right now)
An extra step I prefer to do is remove Kingroot, since it installs a lot of services and keep device substantially slow. If you prefer Kingroot over SuperSU, you are DONE!
Case you prefer SuperSU... Open Kingroot/.../Settings/Uninstall Kingroot
It will prompt if you are sure. Just click Continue/OK
Go back to prompt/terminal and run "adb reboot recovery"
Phone will enter TWRP!
Now, just a few steps!
Go to Install and flash SuperSU
Go to Wipe and do a Factory Reset
Go to Settings and disable TWRP app installer (optional)
And finally go to Reboot and choose System
DONE!!!
Now you have a phone with an unlocked bootloader, a recovery capable of doing a lot of stuff (sideload, wipe cache, backups), and rooted as well.

A really good job, I'm sure a lot of your fellow countryman will find this very useful!

Thanks for the instructions. After unlocking its bootloader, wil it be compatible with any H440 custom rom (single sim operation, of course)? Or the only custom rom we get is Cm12?

Hi!
Well, unfortunately I don't know. I made the procedure, wrote the tutorial, and 2 months later changed my phone for a new one. Can't test anymore.

Yes, it should be compatible with any custom rom as long as your phone is Lg spirit LTE( snapdragon variant ).

Did you try the beta 3?

Whatever the beta was on their website, if you have some sort of other version I'll take it.

Pay attention to the CU number, thats how I got mine stuck on beta 3
but at least it works, jsut dont know if it will ever get upgraded.

I still tried it and I still cannot load into anything. I think I forgot to enable usb debug tho as fastboot fails to do anything, even something as simple as switching slots

12" Chinese Review Mirror Bootloader Unlock/Firmware Update/Theme

Using Ubuntu inside VirtualBox:
Ensure your VirtualBox is setup to see all USB devices, has internet, folder share, and drag & drop enabled.
1. Go to files and create a folder under /home/username/ called “Media”
2. Give permissions to the folder and all subsequent files by right clicking, going to properties, and setting them to allow “create and delete files”.
3. Give permissions for local network share by sharing folder, allowing others to create and delete files in the folder, and allowing guest access.
4. Inside the “Media” folder you will place a modified fastboot zip folder and extract it’s contents into this location. The zip file can be downloaded from here: Modified_fastboot
Now that you have your Computer setup, let’s get started.
--------------------------------------------------------------------------------------------
Prepare Android Mirror: (Plugged into CPU via USB)
1. Power on Android mirror.
2. Go to "Settings".
3. Scroll down and select "System".
4. Scroll down and select "About phone".
5. Scroll all the way down and click on build number until developer mode is unlocked.
6. Click on "Baseband version" 4 times to access EngineerMode.
7. Select "DEBUG&LOG".
A. Enable Never Screen Off.
B. Disable Watch Dog.
C. Enable USB Debug.
D. Allow USB debugging “Always on this computer”, and select “ok”.

10. Device is now ready.
--------------------------------------------------------------------------------------------
Using Windows with Ubuntu installed within Virtualbox:
To get into fastboot:
1. Ensure you have the latest platform tools for windows. This can be downloaded from here:
Win Platform Tools
2. Extract contents to a folder.
3. Open extracted folder, right click in folder, where you see adb.exe, and select “Open in Windows Terminal”.
**** These next steps I found are to be done in a specific order and time so pay close attention ****
4. Type “./adb devices”. Press enter after the beep sound and the 4G loading screen disappears.
./adb devices
Click to expand...
Click to collapse
If done correctly you will see the following:
List of devices attached
XXXXXXXXXXXXXX device
5. Type “./adb reboot bootloader”.
./adb reboot bootloader
Click to expand...
Click to collapse
6. Press enter. - Must be done before the screen goes black and you hear the next beep. If done correctly you will see on the far left:
fastboot mode
7. You are now in fastboot mode. Try not to take too much time with unlocking the bootloader as this may timeout and take multiple tries.
--------------------------------------------------------------------------------------------
Within Ubuntu:
Unlocking bootloader within Fastboot:
1. Open the modified_fastboot folder, right-click then select Open in Terminal.
2. Setup permissions for user by entering the following one at a time followed by enter.

OKAY [0.019s]
finished. Total time: 0.019s
6. Copy the Identifier token.
7. Run this command ; replace XXXXXXXXXXXXXXXXXXXXXXXXXXXX with your Identifier token. Should look like this:
./signidentifier_unlockbootloader.sh XXXXXXXXXXXXXXXXXXXXXXXXXXXX rsa4096_vbmeta.pem signature.bin
Click to expand...
Click to collapse
8. You should have an output like:
Identifier sign script, ver 0.10
1+0 records in
1+0 records out
50 bytes copied, 0.000257562 s, 194kB/s
Identifier sign successfully
9. You should also see a signature.bin file in the modified_fastboot folder.
10. Finally run this command:
./fastboot flashing unlock_bootloader signature.bin
Click to expand...

Update to latest firmware:
1. Go to and read through the Original Post, Original Post in Russian, and ensure your device is the same device or very similar in design. If not you should not update with the mentioned firmware.
2. Download firmware update:
QC_BITE_M5_188_Media_Sleep_2021010619_202101061959_64bit.pac
The tools that will be needed and instructions:
1.Go to this website, https://spdflashtool.com/
2. Download latest version of Research Tool here: Research-tool
3. Follow instructions on how to use the Research Tool here: Instructions
A. Here is the link for the SPD driver you will need: Drivers

7. Now you wait until complete and reboot(s) complete.
--------------------------------------------------------------------------------------------
Additional/Optional:
Not promoting anything, but kinda am. I get nothing in return for advising to use of any tools. This one here has helped me more than i can explain and was created by an OG of XDA, Koushik Dutta, aka. Koush. He is most famous for his work with Clockwork-mod. Show him some support if you like his work.
Tool to control pretty much any android device from your computer: Vysor
https://www.vysor.io
Here is a video showing you how to use the program. It is done with a Firestick, but once I was setup it just found the mirror itself once I plugged it in as well as my cell phone:
--------------------------------------------------------------------------------------------
Now that your bootloader is unlocked and your system is up to date, you may want to customize things a bit as most on XDA do. This is super new to me, like only 2 days working on this mirror.... I did however find a legit app, through playstore, to customize your home screen to not look like so tacky/boring. The app is called Car Launcher. There is a free version and a paid one. Paid version unlocks so much customization. I recommend installing the free version and testing it out. If all works, then the paid version is the way to go. I know the paid works very well with the above firmware. I have tested it quite extensively and so far found only one hick-up. Here are the links.
Recommended Home replacement: Free
Car Launcher Free
PRO Version is much better: cost $4.99
Car Launcher Pro
Whatever you do, don’t use program brightness settings in the themes or Car Launcher. Use the device’s settings.

Hello @po8pimp. Thank you very much for this tutorial, it is very useful. Hopefully someone can make a custom rom for these mirror.
I have a similar mirror, i think from HGDO brand, 4GB RAM 32Gb ROM with the firmware QC_1126bit_M5_1126_media_sleep_2020112517
Can I use your method and install that firmware?
In other hand I cant logout a google account from the mirror. Do you know how to delete and account from it?
Thank you

I will have to check on the firmware ability. As far as the google account logout, you will more than likely have to factory reset the device.

This is the forum you would want to find your firmware for your device in. I recommend if you don't know Russian to get a browser with add on support to translate the pages for you. I use Firefox and Translate web pages extension which works really well.

hi i have this mirror following the guide, "./adb device" command list the device, but i can't get it to go into fastboot mode with "./adb reboot bootloader" command ...is there another method using combination of buttons?
