The only way I could get it to work was the following; however there is one thing to try before you try my way because mine did this also - after the wipe and flash with flashtool etc. The only way I found to get out the bootloop was to do a factory restore after when its looping. So from the boot screen loop hold the power button until it goes off then on then off again.
Then do the process to get into the recovery so hold down and power then release power as soon as the lg logo appears (first one) then press it again immediately that SHOULD get ya to the grey factory reset screen. Press the power button 3 x and it should do a factory restore and boot up this time. First boot may take a minute it should eventually start up.
Failing that try this - Open the lg mobile support tool and connect the phone in download mode (volume up and power with plugged in usb on mine) then go to options and upgrade recovery. it will download a file usually about 2GB then install it, the phone will reboot at 100% on the phone and 80ish% on the lg tool it will then start into the setup feature,
DO NOT disconnect the phone until it gets to 100% and finishes. This way you shouldn't need to do an extra factory reset.
I understand for this the phone needs to be seen on com 4 (it shows on the phone screen) so if necessary go into device manager with the phone still plugged in in download mode and select com ports then select the phone com port then right click >properties> advanced and change the com port to 4. It may tell u its already being used but don't worry it is fine. Save and exit device manager.
please bare in mind these are just my experiences on MY LG D802 however its worked every single time for me without fail and ive done it a good few lol.

Emergency help; Stuck at LG logo

Solved!
Please buy hyelton a beer or a damn new phone. He's a hero.
This worked: http://forum.xda-developers.com/showthread.php?t=2432476&highlight=decrypt
Hey guys, but of an emergency here...
I'm stuck at the LG logo after flashing the Pacman ROM with the latest unofficial CWM, and it seems to have failed at Formatting system. All four touch buttons on the bottom were blue, as if they had been pressed and highlighted. No response from anything.
Reboot. Then it got stuck on the LG logo. I can't access CWM anymore, holding power + vol down does nothing, I just go back to the logo. I'm running a D802.
This was a pretty standard flash for me, I have done this many times, so I was confident in it, but now have no way back into a phone I desperately need within hours.
Process went as follows;
Full wipe, format, initialize install, it failed/crashed/whatever, rebooted, now stuck on logo, unable to access CWM, and obviously unable to access ROM.
USB Debugging was on, but as the ROM doesn't exist anymore, not sure how much help that'll be.
I'll gladly go back to either CWM or TWRP, as well as stock ROM or whatever. I can sort all that out later, right now just need things back in running order.
Edit1: I can't even turn it off. It simply boots up again, so now also worried of damaging display or battery.
Edit2: It's not showing after entering "adb devices". List is empty.
ANY help appreciated.
I'm running Windows 8, and no, I will not be able to reinstall to W7 or Ubuntu.
Thank you

Recovery img flashed to boot partition - hard or soft brick?

Hey guys, I have a samsung galaxy s7 edge SM-9350. I was able to get root access and get the TWRP app. I was attempting to flash the TWRP recovery image, but I accidentally flashed the to the boot partition instead of recovery. After rebooting, I cannot boot the phone. When I hold the power/volume up button I get the option to select recovery/fastboot/normal boot modes, but no matter which one I select, the phone doesn't seem to boot. Do I have any options? I'm not sure if this qualifies as a hard or soft brick.
I have also tried to go into download mode, by holding the power/home/volume down, but that just seems to enter a boot loop. The screen illuminates, but remains black for a while, then shuts down.
The furthest I get into any sort of developer/interaction with the phone is being able to select between Recovery, Fastboot, or Normal modes.
I'm looking for the general search terms to start with. I've rooted my nexus/htc devices before and soft bricked, but was always able to get back via Fastboot/Recovery. This is the first time I've not been able to get into either. Is there some method I can use via the micro SD card maybe?

Install PC SmartSwitch app and try the Emergency firmware recovery option
If that doesn't work then you may need a Samsung Repair centre

Ugg... I had installed Smart Switch, but it doesn't recognize that my phone is plugged into the PC.
It looks like in order for it to work my phone has to be in Download mode or Recovery mode, depending on what guide I read.
And I can't get into either mode at all
Thanks for the response!

I assume Odin doesnt recognise the phone in any situations?

That's correct. My windows PC with the Samsung drivers no longer recognizes that a device is plugged in. I just tried a USB jig. Pins 4 and 5 of the microusb joined with a 300k ohm resistor and it still doesn't go into download mode.

Sadly you probably need a samsung repair centre
Please let me know how you get on with a fix

Does Odin not recognise the phone when you put it in to download mode ?? i used Kies to recover the firmware rather than smartswitch although Kies tells you to use smartswitch it still let me use it to doe the firmware recovery.

LG V20 Device is Corrupt and BootLoop

Hey all! Hopefully you can help with this issue. I have had this phone through T Mobile for a few months now, and am stuck in a real bind. As the title suggests, I have a boot loop issue and Device is Corrupt issue as well. The red Triangle is an issue with the OS. I cannot get the phone to boot to Android, nor get into recovery. I can however bring up the IMEI menu, which displayed the IMEI. I really need help, as this is my main contact for job search and family.

Im on sprint so this method is unavalable to me.
Tried LGUP? you have the ability to shoehorn a KDZ file in whicj will bring your phone to stock
As this is a no go for the ls997 i have no idea how this is accomplished. Check the forums for said method.

I will definitely look into this. I just want my phone back TT.TT lol

I wanted to chime in, I've got the same issue as OP.
What's broken:
turning the phone on normally - displays an LG logo; gets stuck, won't proceed past this point
holding VolUp while connected to PC - displays IMEI; won't enter download mode
holding VolDown - displays IMEI; won't enter fastboot or recovery mode
So, there's no way to get to recovery. I'm stuck with a $400 brick that displays a logo or an IMEI number.
LGUP w/Uppercut doesn't work either, shows up as an unrecognized device, and it wouldn't matter if it were recognized, because I can't get the phone to download mode to restore a stock .kdz.
I just ordered the phone on the 4th from Amazon, so I'll see if I can return it/get a replacement, but I'm guessing I won't be that lucky. It does display the orange "WARNING: Bootloader Unlocked" screen, meaning it's very easy to see that the warranty has been voided, so I guess whatever support I get is a crapshoot.
Again, since I can't get to fastboot mode, there's no way to restore to stock and relock the bootloader before returning it. Kinda dug myself into a hole here with no other options.

I got it to install! Now to just play the waiting game and see what happens. I had to do some finagling to get it to work, but it works.
I found a H91810 KDZ, I started Uppercut which loaded LGUP, click on UPGRADE, then selext the KDZ file from where you saved it. Should work. Also make sure all of your drivers are up to date.

Were you ever able to get this resolved? I'm having the same problem, except it's not showing anything about the bootloader that I can see

Ok, I seem to have my device back up and running. The step I was missing was to remove the battery, disconnect the USB cable, put the battery back in, hold volume down but don't press power, instead connect usb cable. This got me into fastboot and I was able to recover from there.

this might work for you!

okay so holding VolUp while powered down and plugging into pc will bring up download mode if its still there,
if you have twrp installed prior to this red triangle then pull battery/put back battery. hold VolDown and power at the same time, as soon as LG logo comes up release power button (fast) and then hold it back down again while never letting go of VolDown. this is the factory reset hit yes for both questions and it should reboot phone into Recovery mode. some times you have to do it twice to get recovery (twrp) to pop up! i hope you have bootloader unlocked and twrp.

If using the LGUP you must get the G4 Dll file for it to read the phone and com its on. i believe its a common.dll file i cant really remember...

What model do you have?
You can put the phone to download mode (even if screen displays glitchy gibberish screen) by taking out Battery first, put battery back in after 10 seconds. Then just press Vol up and while keeping it pressed, connect to USB. If you have drivers installed, your phone will get recognized by LGUP. Now from here you can flash the stock rom.

no OS, no TWRP, no fastboot..... no chance?

when reinstalling a ROM earlier today, I got an error 7 ... no problem. probably TWRP problems... so, i go to reboot phone to recovery to begin fresh, and now, TWRP boots, but the screen flashes blank every couple seconds, for a second, then the TWRP splash screen comes back up. blank screen, then TWRP splash screen again. never gets further than that. because I dont have an OS installed, i cannot access debugging for adb. because i deleted my OS, i cannot allow fastboot, to flash a new recovery and begin again. ..
I am broke, and cannot afford to pay for a new replacement thru insurance or to just go buy a junker phone and make do with that.
am i ****ed, or is this recoverable...? ive been searching the forums, but cannot seem to find the answer, and im starting to get nervous enough that its sorta beginning to compound my problems more than i can deal with.
edited to add again: .... battery removed + volume dn then insert battery will not enter fastboot. im about to paperweight this ****.
again edited - Sprint LS997 is phone model. no TOT'ing for me.

What about if you remove the battery, put it back in, hold volume down and then plug the usb cable?

tried this. still a no-go. phone screen does not power on when trying this or any other combo of steps. LAF works, which is vol+ and plug in USB cable. odd that vol- and plug in USB cable does nothing. maybe faulty vol+ button? never had a problem with that button functioning before now. i have access to: LAF (download mode), and TWRP. However, TWRP 'flashes' off n on... i see the splash screen for a second, then screen goes blank, but still powered on. then splash screen again. rinse, and repeat. no response to touch or vol/pwr buttons. tried pulling battery upon TWRP splash hoping this clears cache, but still just same story afterwards.
would having access to fastboot even matter, since I have no OS install with which to give fastboot/adb access anyway?

From fastboot you can reflash TWRP which from where you can reflash the OS which would unbrick the phone.

If you have access to download mode, can't you reflash your phone using the LGUP with the backup that did in the first place?(you did a backup of the original OS right?)

Sounds like empty or bad battery to me. When did your phone start acting up upon ya? Right after root or you had it working with root etc before u ended up into such situation.
Also, as XblackdemonX pointed out, you can still use LGUP to stock.

I'm pretty sure that happened to me. And I fixed my H990DS by flashing kdz file in download mode with LG BRIDGE.
There's a guide about how to unbrick any v20 around here.

@elijah420 What software version were you on before this started? Why does it matter? If you were on ZV7 or earlier, then you can flash a VS995 KDZ in download mode, root it, and then fix your phone. If you were on ZV8 or later, then you still might be able to salvage your phone, but you will have to run firmware from another model since you will not be able to root and flash back to Sprint firmware if you were ARB 1 or later. Better than having a totally busted phone though.
Last possibility is to use the debug firehose that I have, but that is an even bigger unknown than running firmware from another model.
