Why update phone stuck at bootloop? 20i to 20o. - T-Mobile LG G4

My phones stucks at bootloop after ota update, so I decided to flash kdz via LGUP. (v. 1.14.0.3). Then I tried it two times and I have no errors both of pc and phone, but phone stuck at lg logo(one time T-Mobile logo appears and suddenly rebooted itself). Also, the second time I get some unexpected things like the phone says it is h81120o but LGUP recognize it as h81120i.
Anyone has this problem? Can I flash again h81120i?
Edit:Thanks for everyone who helped me but I am so bored to deal with it. So I give up to try and I will use my old phone. (All photos are removed by me)

i think its normal.. it says 20i cause it was on 20i.. once you flash it. hte next time it would say 20o..
as for the reboots i think you have the infamous bootloop.. so it must be sent to LG for repair.. sorry.
noooooooooooo dont flash 20i
20i its antirollback V2
20o its V3 if you do itll brick phone.. so you stuck on 20o...

I'm not in U.S. It was bought by my friend when he was in U.S. So, No option to send it to LG. I talk with lg service center, they says I have warranty but they need a physical address.
My phone optimizing 55 apps when first boot then finishing boot and then it reboots and stucks at T-Mobile screen. Just for once it ask for first setup configuration but it shutdown because of my battery is too low. After that it doesn't boot any more. Do you have any suggestions to back it live? I have download mode and factory reset and pc can recognize the phone. But this is first time I deal with this issue.
<deleted>-Please look for photos what I have first time it boot normally after factory data reset.</deleted>

best thing is to have it repair... but if you cant.. then no.. theres a TOT file that disbles big cores .. but only for h815..

[Q] Is My P970 Completely Bricked?

My phone has the Nova Rom installed in it for almost a month already. Today I used my phone for playing games, browsing the web and after that I turned off my phone and turned it on again, instead of booting up it's stuck on the LG Logo with the four softkeys blinking. What the hell? I didn't do anything but my phone got bricked? I tried to unbrick my phone using these methods:
http://forum.xda-developers.com/showthread.php?t=1275315
result, after flashing my phone reboot but it's still stuck on the LG Logo.
http://forum.xda-developers.com/showpost.php?p=15975608&postcount=2
result, still the same stucked at LG Logo.
and lastly
http://forum.xda-developers.com/showpost.php?p=15039107&postcount=16
result, still the same stucked at LG Logo.
Is there any other methods for unbricking my phone? Is my phone totally bricked and should I send it to the service center?

Nope mate, it didn't work. I can't go to it. I tried to spam the buttons many times to go to it before I flash it with stock V10A. I tried to flash it with V10E still no luck.
Update:
I sent my phone to service center two weeks ago, I visit them today and they said that they will be changing my Black's motherboard and I need to wait one week more. Damn I can't wait.
make a nandroid back up always. and use "adb recovery reboot" if phone bricked...

[Q] G2 Rooted -> Flashed Stock -> OTA -> LG Logo Brick

So I've had my phone rooted for a while on 26A using Xdabbeb's VS980 2.20. Worked well, but I started having some issues. In trying to fix those issues, I backed everything up and used this guide to revert back to stock 11A (TOT method).
Reverting back to stock worked well. Verizon started pushing OTA's (which I haven't had for a very long time). I believe I got up to 29A. However, Verizon pushed one more OTA, phone rebooted, installed step 1/2, and then step 2/2.
This is where I'm stuck. After finishing step 2/2, the phone rebooted, showed the LG logo and stopped.
I can get in to stock recovery mode. The green android flashes on screen briefly, restarts, but it get's stuck on the LG logo when it restarts.
Download modes doesn't install drivers on PC to show as a COM port. LG Flash Tool can't find it when I try to flash anything on it.
Any ideas on what to try next? I'm completely lost on where to go from here. Any help would be extremely appreciated.
TL;DR: Stock LG G2 phone is stuck on LG logo after OTA update to 39A. Recovery isn't working. Download mode isn't working.

Unfortunately, no. My phone is currently on it's way to LG to see what they can do with it. I won't know any more until late next week .
Got the word back from the repair department. The LCD screen was bad or connector (pretty much knew that). Not sure if they got it to turn on, but they were going to charge $150 to repair/refurbish it (90 day warranty). I called to get more information but the person I talked to didn't seem to know any answers to my questions, so I gave up.
I opted to buy a new LG G2 from eBay for $195 (1 year warranty).
When I get the old phone back, I'll see if it boots.

Stuck on LG Bootscreen only download mode, LGUP didn't work

Hey Xda-ers,
I'm freakin out about my phone. I was using hangouts this morning and it just rebooted itself and got stuck on boot screen. It has NEVER done this before and always worked fine. I was on USS Enterprise ROM I believe. I can only get into download mode, so naturally I tried to flash stock h81120o (the version I was already on and rooted) and LGUP completed fine. Only my bootloader was still unlocked and it still was stuck on boot screen. Does anybody know what I can do to at least relock the bootloader so I can do a warranty claim with T-mobile....or get my phone back working if this is not catastrophic.
Oh I also tried holding down & power, no recovery...and cannot use the buttons to factory reset either. Then it loops and get stuck again.
Ditto

Did you ever find an answer to this ? Almost the same thing happened to me , i updated H81120p Extreme and phone booted back into Boot Screen and stayed there forever. I tried flashing H81120p using LGUP but am stuck on boot screen still.

How can i tell if this is indeed a hardware issue ? I am guessing it is though also the serial number falls in the problem range.

I know I have done few things wrong in confusion, but realized later on. It is H811 TMO model for sure.
I did select refurbished while using LG UP
My phone is not completely dead.
Pressing power button it stuck on LG logo with unlocked boot loader msg. not going to the bootloop.
I am unable to enter download mode, it responds but freeze before entering download showing 4 blue dots.
I am able to enter recovery but I can not hard reset as it always freezes on 2nd hard reset screen and not formatting.
No charging, Device Manager shows nothing.
Is there a way to recover??
I am not sure, If this is some hardware issue or emmc fault , Please help me on this..

Recovering soft brick/bootloop with LGUp?

Hello all ,
Device is Lg G4 H811 with 20x firmware.
I was trying to root and flash a ROM, but I screwed up at some point and apparently fouled up the bootloader. I got as far as flashing SuperSU, but after that I could not boot into recovery using the button-press method. So I used ADB to send "Fastboot boot TWRP.img." The readout said something like "Downloading boot.img" and the phone now won't boot. It will occasionally get to the T-Mobile splash screen, but will go no further. Usually it's stuck at the LG logo.
I have factory reset with the button-press method, but it doesn't make any difference. I can get into download mode.
I assume I corrupted my bootloader, and I want to use LG Up to factory reset using the 20x KDZ from Mingkee. Before I make matters worse, though, I wanted to make sure I'm on the right track.

Nevermind. Figured it out and I'm back up and running. This is an awesome community, but sometimes there's almost too much info to wade through.
Glad you were able to get your phone back up and running because what you described seemed like a bootloop issue that LG G3 and G4 are so notorious for. May I ask what worked for you or how you fixed it? I have a phone that is acting same way and I put it away thinking it was bootloop. Thanks.
