I think I'm stuck in boot loop too. I've been waiting for over 20 min and thats not normal right?

I used ULM version to refurbish.

It's a little weird because I got "refurbished" phone that is ULM version thinq. I also found that LG made unlocking available for certain models and I thought mine would be okay. But at least according to them from my model id and such this is a Sprint phone?

Do I just repeat last step and try to maybe partition DL this time? Do I get sprint version?

Help is much appreciated! :)

I think you may have bricked it, I just gave up and had an IT guy try to do it for me, mine is bricked for good now won't even turn on. If you want my advice get a different model and save yourself the hassle.

I'm having problems with steps 10 to 13. Can someone please explain them to me in detail? Also, I'm getting multiple files called "ReadData...bin". I first had 2 now there's 3. Which one(s) do I rename to what? I'm so confused. Please SOS.

I'm stuck in Step 17. Download & extract "fastboot driver.zip" and follow the instructions inside the README.txt.

Where is the link to downloading this fastboot driver.zip?

Hello all!

I would appreciate some help...

I'm stuck on step 24...how can I get back to EDL mode....my phone is not found on QFIL and the PARTITION MANAGER field is grayed out :(

24. Go back in EDL(9008) mode, open qfil -----> press on "tools" -----> press on partition manager ----> search abl_a ----> right click on it ---> load the abl_abackup.bin located on dextop. Repeat the process with abl_b(abl_bBackup.bin), laf_a(laf_abackup.bin), laf_b(laf_bBackup.bin). (EM and EMW models have to restore only abl_a & abl_b). After you are done press on save partition file then close.

Phone is stuck on FASTBOOT MODE and I get this message when I try to go to recovery mode or turn it off etc?

I have a G7+ThinQ
Model: LM-G710EAW
Hardware Rev 1.0
Android 8.0.0

Can I use this guide to unlock?
My aim is to install Magisk to root.

Also once unlocked. Can I just upgrade to Android 9 and will still be unlocked?

Thanks.

Nevermind, I did it!

(I really don't understand step 20 "20. Open the CMD inside the extracted fastboot-tools.zip and type: fastboot flash frp (drag and drop over the cmd the frp.img), it should say OKAY."

I don't know what I have to do exactly. I open the cmd link in the platform-tools folder and I write "fastboot flash frp", but it says

"
unknown partition 'frp'
fastboot: error: cannot determine image filename for 'frp'
")

Because you didnt drag the frp image over the cmd so it introduces the path, it cant flash something that its not specified, when you drag the file over the cmd with your cursor it will automatly put the path for you.

It is normal, only EAW,EMW and EM have fastboot mode, others would have to erase laf_a and laf_b in order to gain fastboot mode acces, but you lose access to download mode, you cant have both in the same time, its either one or another, so backup your laf partitions and restore them only when you need download mode.

    IMPORTANT: NEVER ERASE THE ENTIRE FLASH (IT WILL BRICK YOUR PHONE **STILL CAN BE RECOVERED**)
    IMPORTANT: FOLLOW ALL THE STEPS IN ORDER TO UNLOCK BOOTLOADER SUCCSSEFULLY;
    DISCLAIMER: I AM NOT RESPONSIBLE IF YOUR PHONE BRICKS! YOU ARE FOLLOWING THIS GUIDE AND ITS YOUR CHOICE TO DO IT OR NOT TO DO IT AND YOU'RE THE ONE DOING IT. I JUST WANT TO HELP OTHERS OUT.


    Requirements:
    - Windows PC/Laptop;
    - USB-C cable;
    - Patience;
    - Unlock LG G7 ThinQ;


    STEPS:


    MAKE SURE THAT EACH STEP IS FOLLOWED IN ORDER NOT TO DAMAGE YOUR PHONE
    1. Download UnlockG7.zip and extract it.
    2. Install 9008 usb driver and QPST.
    3. Reboot the pc.
    4. Turn on usb debugging in developer options.
    5. Boot the phone in edl mode:
    I) Connect the phone to the PC;
    II) Hold VOL- and Power;
    III) As soon as the screen turns black repeatedly press VOL+ while holding VOL- & Power button.

    Video tutorial:

    6. On the windows PC go to device manager ---> Ports and it should say Qualcomm HS-USB QDLoader 9008 (COM x) or "QUSB_BULK_CID: xxxx_SN: xxxxxxxx";

    7. Setting up QFIL:
    I) Run QFIL;
    II) Set Build Type to Flat Build;
    III) Programmer path: select the file "prog_ufs_firehose_Sdm845_lge.elf" inside the extracted UnlockG7.zip;
    IV) At the bottom right corner change device type to "UFS".

    9. Press on "Tools" and then press on "Partition Manager";
    OlUOEEJ.gif

    10. A new window should show on your screen with every partition on your phone. If you get sahara error, you should make sure you installed the 9008 mode drivers right or reboot your pc, reboot your phone from edl mode by holding volume - and power button for 10-30 seconds, then getting back to edl mode (step 5);
    11. Search the partition called "abl_a" right click on it and press "Manage Partition Data" then press on "Read Data" (this will backup your current partition) then press on "Load image" and load the V35abl.img from UnlockG7 folder.
    12. Press win + R and run %appdata% , navigate to Qualcomm --> Qfil --> COM_X (X --> the port that your phone was connected at (step6) and you will have a file named readata...... .bin rename it to Abl_abackup.bin;
    13. Redo step 11 & step 12 but instead abl_a repeat the process with abl_b;


    STEP 14 & 15 ARE NOT NEEDED IF YOUR LG G7 MODEL ITS EM, EMW OR EAW
    14. Search laf_a partition right click on it and press "Manage Paritition Data" then press on "Read Data" (to backup it), follow (step 12) again but name the file called readata... to laf_abackup.bin then you press on erase. (NOT "ERARSE ENTIRE FLASH") ;
    15. Follow (step 14) but instead laf_a repeat the process with laf_b;


    16. After you are done press on save partition file then close.
    17. Force reboot the phone (Hold volume - and power button for 8s) and immediately hold only volume + (For EM, EMW & EAW its volume -), it should get you in fastboot mode. (If it didn't work try again);
    18. Download & extract "fastboot driver.zip" and follow the instructions inside the README.txt;
    19. Download & extract "FixFastboot.zip" and follow the instructions inside the README.txt;
    20. Download & extract "fastboot-tools.zip";
    21. Open the CMD inside the extracted fastboot-tools.zip and type: fastboot flash frp (drag and drop over the cmd the frp.img), it should say OKAY.
    22. Press volume + until you see on your phone's screen "reboot to bootloader" then press power button and wait for it to reboot back in fastboot (bootloader);
    23. Type in the CMD: fastboot oem unlock . It should say "erasing userdata...." and wait until its done.
    24. Move the backups you have done in steps 11,12,13,14 (For EM,EMW & EAW models only from step 11 and 12) on dextop.
    25. Go back in EDL(9008) mode, open qfil -----> press on "tools" -----> press on partition manager ----> search abl_a ----> right click on it ---> load the abl_abackup.bin located on dextop. Repeat the process with abl_b(abl_bBackup.bin), laf_a(laf_abackup.bin), laf_b(laf_bBackup.bin). (EM, EMW & EAW models have to restore only abl_a & abl_b). After you are done press on save partition file then close.
    26. Force reboot your phone (Hold volume - and power button for 8s) then immediately hold volume + only, it should get you in download mode;
    27. Download & extract "How to flash KDZ Firmware.zip" and follow the instructions in README.txt;


    Congratulations! You have successfully unlocked the bootloader of your device.

    My g7 is the sprint G710PM and currently it wont start. is it possible to unlock bootloader still and fix, or do i have to wait for LG's G710PM .kdz?
    ive tried a LOT of things to fix it but nothing has worked and probably did more harm than good, though i can still put it into 9008 mode for qfil. though i get RED case when booting to fastboot which wont allow a fastboot flash connection
