Help - LG G8x Stuck in a Fastboot Bootloop, Bootloader is locked. - LG G8X ThinQ Questions & Answers

Ok, I was following a guide on how to cross flash the LG G8x .kdz file to get Android 11. (the G8x AT&T variant refused to update).
I followed all of the instruction, but while using LGUP, I got a weird error code that I could not find information on anywhere. Now my phone is in a fastboot bootloop, and the bootloader is listed as locked.
Is there any way to get into EDL mode? I have a number of files I could restore using QFIL, but cant get into it from the bootloop.
Are test points an option? if so, which are the test points I need to use?
Any help or advice is welcome, I'm able to take the back glass off if I really need to although I would really prefer not to.
Thanks in Advance!

Hey, I have a G8x , I faced the same problem, all I did to fix it was to boot into edl mode by hitting start on fastboot and pressing the edl button combination with your phone being connected to PC i.e hold down power & volume down and keep pressing the volume up as soon as the screen turns black

[Q] P500 stuck in emergency mode, not detected by computer

This all happend while trying to downgrade the baseband and it just stopped at about 25% and stayed there for ten minutes, I attempted to reflash and the same failure happend, I then rebooted the phone and it has been in emergency mode since then with no detection at all.

check downgrading ur phone detail just flash ur desired android version.
if sucessfull via lgmdp(latest method) search threads for lgmdp method or use kdz which solved all probs.
Try to enter emergency mode with vol up + back key + power button (not just power button) and then connect it to usb.
I have tried the kdz(after emergency mode issue) and lgmpd method already as it was required for the baseband flash the first time, I have clockworkmod recovery installed and cannot boot to that, was downgrading the baseband so I could go back to using CM7, as we speak I tried using CDMA setting in KDZ and I seem to have gotten a response, will update with whatever method works to unbrick
well after using KDZ method in CDMA mode, with shaking the phone, crossing fingers toes arms legs and eyes, I flashed riginal firmware and unbricked my phone, thank you for the links, after about 8 different pages I managed to get it working thank you all

try 3 button combo home+vol down + power and see if it comes out of lg logo and boot
I'm stuck in the Emergency Mode!! yellow screen with my P500 too.
I tried with KDZ Updater in all possible combinations and got the error "Upgrade error WParam:100. LParam:502" at each attempt.
I tried these rom's: V10A_00.kdz, V10B_00.kdz, V10E_00.kdz, V20B_00.kdz.
With LGMDP THUNDER v1.5, but I run into this error, after pressing the Start (write ROM button): Error! Partition Table.
Help!
I opened a dedicated topic here http://forum.xda-developers.com/showthread.php?p=17307504#post17307504.

Hello, my P500 is not detected any more by computer!
I looked over the internet and it seems a hardware problem. The phone is charging but cannot be detected as hardware. Unfortunately to resend it to warranty I must first remove Superuser because I rooted my phone. Is there any way to install the firmware once again from the sd card? I cannot make it through a computer because as I said before is not detected. I have custom recovery installed: ClockWorkMode 5.0.2.0. I looked over this forum and found some custom Recovery Zips, but I don't know how to use it. Any idea please? I must get rid of root access so I can return my phone to warranty! Thanks!

Download Fla**** (http://forum.xda-developers.com/showthread.php?t=1453660) and a fastboot file for your version. There's a list over here: http://forum.xda-developers.com/newreply.php?do=newreply&p=22219625
Extract both files, and put them in the same folder. Go to AP fastboot mode, ensure that you see USB connected there. Run "FlashME.bat".
i wrote a HOWTO, you can follow it here:

loldevil - i have tried that and it didn't work. Thanks anyway
I will try to follow the other two methods and see how it goes

Bricked for good? (Revisited!)

Hello all!
I am back to see if anyone has any more ideas with what I can do to resurrect my LG G3. To recap, I tried to flash android 5.0 and I had forgotten to re flash the stock recovery prior to doing so. Long story short I completely botched the process and I am left with a LG G3 that can only access system recovery selection menu. When ever i try to just boot the phone by holding the power button, it shows the G3 boot image and then an error in the top left reads: "Boot certification verify".
From there, the phones screen turns off and the led flashes amber and blue until I pull the battery.
If I remember right, I need to find a way to re flash download mode but it has been several months since I tried to repair it..
Hope you guys can provide me with some input!
I linked a video I made of what happens when i try booting the phone below:

I had to do a warranty exchange through the insurance. It is not worth
The effort since we don't have fastboot. Got a brand new replacement.
Hope you can do what I did. Told them the truth that the phone
Would not boot up. Nothing else.

Totally would have done that had I not dropped my phone in water:silly:
Just pay the hundred and use the insurance, you can report it lost.
This way you can have spare parts.
You can also replace the motherboard. Sometimes you can get them
For 100.00 but I'm only seeing them for 150.00 on eBay.
Id like to hear that you can unbrick this phone but I doubt it with
No fastboot. Good luck.
Since it will boot cant you just usecthe lg flash tool thingamajiger and flash a .kdz

your phone is soft bricked, You need patched fastboot to reboot in EDL, a Fastboot ROM, and Mi Flash Tool. Goodluck.

vs880 Brick Help

I have a LG G Vista VS880 that I rooted with Kingroot. My next step was to nuke the LAF, go into fast boot and use fastboot oem unllock to unlock the bootloader so I could install custom recovery. I got as far as nuking the LAF when I had to stop and fix dinner for the kids. When I got back to the computer I forgot that I hadn't unlocked the bootloader yet and flashed the custom recovery and a magisk patched boot.img using flashify. Now it will not boot into system or recovery. I can get it to boot into fastboot mode by holding the volume up button while plugging it in but all my fastboot commands are locked. I have searched the forums and have found nothing except some info on getting into QHUSB mode by shorting out the test point but that post was for the G3 and when I took off the back plate the configuration was different and I didnt want to mees my phone up any worse than I already had. I just want to get back to stock and start over. Can someone please help or at least point me in the right direction?!?!?!? I would welcome any assistance!
