OK...I got an under warranty, new replacement LS980 1.5 months before I left Sprint to go with a Nexus 6 on Cricket. After the phone had been sitting my drawer a few months, I got around to rooting it and decided I'd try to put Clouldy 3.3 on it. Upon the installation boot of the ROM I remembered something about using this Sprint phone on AT&T and thought I'd try to install the D800 option to see if it could be done. After all, I'm done with the phone.
Well...that didn't turn out so good. When I try to .tot it back to factory, it won't accept the .tot since the LG Flash tool thinks it's a D800. I found a .dll that was suppose to work with any .tot file, but that didn't work either.
So...now the phone has a pattern of booting into the Cloudy ROM for about 30 seconds then crash into bootlooping twice followed by it starting over again by going into the rom for 30 seconds. Anyone have an idea on how to completely wipe this phone in hopes of getting a factory image back on it?
Thanks!

First let me say ive used this site many times and never needed to post as all my questions were already answered, so for the many times ive not needed to post thank you all for being so great and helpful!!
That being said im hoping im just using the incorrect rom or going about it wrong. we switched carriers at work and my sprint lgog is sitting in a drawer while my wife uses a droid 4 on a regional carrier because they cant flash phones running JB. So for mothers day i thought i would downgrade to ICS and get this phone flashed for her. Thus far ive managed to root, unlock bootloader and fix two softbricks using teenybin's work. The softbricks came after trying to install both LS970ZV9_ODEX_STOCKROOT_1_13 and LS970ZV9_DEODEX_STOCKROOT_1_13 using twrp. I selected backup and wipe before doing both. Is there a different rom i need to use post VZB to install a ICS rom? or are these roms ok im just installing them improperly? TIA
*update* after trying to install the LS970ZV9_02.bin update with lgnpst the phone hung at 85% and upon reboot would hang at the 4glte screen, I tried teenybin unlocker again and the phone wouldnt boot at all. The lg logo would flash and then blank screen...i couldnt seem to toggle the power at all and it wouldnt even charge on wall charger. after 20 mins of frantic "oh #^#$" button pressing i finally got it to go into recovery mode and recovered back to zvb. It seems mostly back to normal now other than the wifi doesnt seem to be on even though it says its on, no emblem in notification area and wont connect to my wifi when told to.
*update2* after doing factory restore i got my wifi working properly. So i then rerooted and then reinstall teenybin with lgnpst i was able to get into twrp and restore my primary backup.... So now i THINK im back to square 1, rooted, unlocked vzb...at least everything seems to be back to normal. 3rd time is the charm which in this case means i think im going to wait to hear from someone more knowledgeable than i before i screw something up i cant fix
4th attemt 4th fail
so i tried to flash LS970ZV9_02, a totally stock unrooted, locked rom i found here on xda...i did a factory reset before booting into twrp, wiped cache and dalvik, loaded the rom and it boot looped....:crying: i dont know what im doing wrong unless these phones just refuse to downgrade....
I suggest you get on the optimus g IRC. They are very helpful. You may need to find the older radios and flash those after you downgrade. LGNPST should work, normally when it reboots at 85% its a good indication that it worked properly. Perhaps you could find a copy of the ls970zv8.bin and try to install that. Good luck.

Hey all,
The other day I used my G Pad as normal, went out came back a few hours later and found all my apps to be crashing. I figured something was just acting up and a reboot would help. Rebooted, got stuck in a boot loop. Tried to factory reset, no luck. Tried using the LG Mobile Support tool, then factory resetting again, still boot looping.
It still charges, turns on, can get into download mode as well as the factory reset screen, but none of those things are getting me through this boot loop.
Prior to all this, I was running stock with root. That's it. Never flashed any ROMs or ran any crazy apps. I'm gutted this is happening after I've used numerous Android devices in the past that I rooted, ROM'd, etc. and never bricked.
Is there anything else I can try? It's out of warranty and I imagine LG repairs would cost nearly as much as a new unit caught on sale.
Appreciate any help. Thanks.
Try using smartflash tool. Not sure if it will work on the GPad but can't hurt if nothing else works

Symptoms are exactly what I experienced a couple of weeks ago. Like you, I tried factory resets and all options in the LG mobile support tool - no luck, it continued to boot loop. Mine was rooted but stock, like yours.
Sorry to tell you, I sent mine to LG (it was still under warranty), and they had to "replace flash RAM", according to the ticket. Very quick turnaround,and it's working perfectly now. I don't know what the process would cost you.
Hope you find a solution...this is a perfect tablet for my uses,and I'm glad to have it working again.
There is an offline LG flash tool which allow you to set up a http server and cheat the LG support tool to flash a local kdz ROM file. Since you can enter the download mode. This way definitely works. Just search the offline kdz tool in the forum.
I was on 13B rooted, then flashed the stock system to return to unroot status. Everything worked fine. Plugged into computer and Verizon Upgrade Assistant suggested upgrade to 13C, so I bit. After a 4 hour (!) download of a 2 Gb file, the upgrade install proceeded without incident, and resulted in a successful completion according to the Assistant. Phone started booting and the Upgrade Assistant re-read the phone as being on 13C, but, the phone stalls and refuses to boot past the Verizon red splash screen. I have pulled battery and tried numerous times to boot, with no luck. It just sticks at the same spot.
Any suggestions? I'm nervous about re-flashing 13 B for fear of bricking it, so perhaps flash 13C kdz?
Thanks in advance for any help.
I have now tried flashing the 13C kdz unsuccessfully a number of times. I verified the checksum on the downloaded kdz file, and attempted to flash it on three separate computers where I had successfully flashed the G4 in the past. Each time that I tried flashing the 13C it reads: "Required Information cannot be found. Contact the system administrator."
I am still stuck here. Even in the flash tool, the phone is read as having 13C on it, but it still will not boot past the Verizon splash screen. Any thoughts on whether I should dare try flashing 13B, or would I end up with even more of a brick then I have now?
Thanks again.
DO NOT FLASH 13B!
Isn't Android 6 24c?
I got stuck on the Verizon screen, but a wipe fixed it at that point.

Thanks, and you are correct on the number, MM is 24C.
May I ask, how were you able to wipe when stuck on the Verizon splash screen? I would love to do that if possible.
Thanks again.

Hold volume down and power on if I remember correctly to put the phone in recovery mode. From there you can choose to do a wipe/factory reset.
I had issues with way long boot times, the wipe fixed that, but then apps kept FC. I ended up downloading the KDZ file and used the flash tool to reflash 24C. Everything is stellar now.
Thank you so much, mikeewhite! I followed your instructions and they worked perfectly, so I am back up and running. You are the reason that I love this list so much, as there are so many people like you generous with their time and advice.
I got my LG G4 from Verizon about a year ago. In January, my phone shut itself off and got stuck in a bootloop, just showing the LG screen then resetting. My boyfriend was able to get it to turn back on using the USB debug mode but he's now in Asia until June. I came back from a long trip to find that that no longer works. I downloaded SDK and tried doing a reboot again and it still just reloops the LG screen. The phone is running stock firmware, bootloader hasn't been tampered with, and no attempts to unlock or root the phone have ever been made. Is there anything else I can do before resorting to the factory reset? If I can't fix it, is there a way to get the data onto a drive before resetting it?
My rooted 1.2yr old VS986 started bootlooping a few days ago. It will sometimes boot if I let it sit in the freezer for a bit; if it boots, usually it will run for 5-20minutes before it quits again. It's able to go into recovery mode (pwr+voldown) or download mode (pwr+volup) without freezer treatment. In recovery mode there is text at the top that reads "modified".
I already have the warranty replacement phone. Before returning the bootlooping phone the Verizon employee warned me that in order to avoid a potential $300 charge, I should get it back to stock before sending it in.
Is it as simple as flashing the VS98613B kdz while in download mode following the steps here: [Guide] LG G4 Stock Firmware (Go Back to Stock) KDZ & TOT Method, or is there something else I need to be aware of? Has anyone ever flashed an LG G4 with the infamous bootlooping issue?
If it's going to need more time to complete the process I can remove the circuit board and heat it up with a heatgun in an attempt to reflow whatever connection busted.
EDIT: Went ahead and did it. The phone bootlooped at 83% so I'm not sure if the roms any good. But the good news is that the recovery menu now says "Official"!!!
Thanks for the info. Gf phone started doing the bootloop last night gonna try out the freezer method to recover some photos. So far haven't been able to get recovery or download mode to work.

As long as it says official you'll be good to go. If you're sending it in for warranty repair, LG will just replace the mother board without checking the software. You can also just use insurance and get a new phone, just have an "accident".
