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.

I'm new to the development side of Android and I bought a ROOTED phone from a Co-worker. Well my phone tried to do a software update and the phone is stuck in a CWM boot loop. Me not being familiar with CWM or ROOT, I pressed the factory reset button in CWM. Now I am unable to fix it. I have tried ADB sideload to load ROMS to the phone. They will say they are installed but then it will just go right back to CWM. I am trying the LG flash tool now but my phone will not go into download mode. Can anyone help me, please. I love this phone....

Can you get into clockwork mod without it looping
If not try command
Adb reboot recovery
Chances are previous owner has some Roms saved on the SD card
In the download folder
Keep in mind Roms are carrier specific on this phone
Yes it boots into CWM recovery and I accidentally wiped everything. I am trying to use the LG flash tool but it will not even go to download mode....
In recovery factory reset clear your cache and dalvic
And try sideload again,if it doesn't work try pushing the file with adb
If you can't get that pm me and I'll troubleshoot with you.
D950 on LG logo
I have a D950 only boots to the LG logo. I rooted the phone and then tried to install CWM. I didn't know about Freedom Flex then, so i used a forum post to try and do it. I successfully got CWM on the phone, but now it won't boot past the LG logo (also boots to CWM, I think it'll go into download mode). I'm not sure if I did any of it correctly, but I've tried CWM, ADB, LG Flash Tool, Odin, etc to somehow get the phone working again to no avail. I'm not even sure if anything can connect/detect the phone. If there's nothing I can do then fine, but if anyone can help/try to help please do. It was a nice phone an i'd love to have it working again, its been so long.
Hi
I have an AT&T XT1058 with locked bootloader, on 4.4.4
I tried to rest it to factory, but it got stuck on 'Erasing...' (with the little droid) for more than an hour, so I reset it.
Since then it won't boot, only keep stuck on 'Erasing...'. I've tried reflashing it with ATT_XT1058_4.4.4-KXA21.12-L1.26_CFC_1FF both using RSD lite and manually using mfastboot, but no luck - the phone still boots to 'Erasing...' and sometimes after that to the recovery.
I didn't find anything in relevant threads. Does anyone have an idea?
Selecting 'Factory' in the bootloader seemed to fix it.
It is more comlicated than that
The phone does boot after selecting 'factory' in bootloader, but only once - turning the phone off and on again brings it back to its 'erasing...' state. Besides that the phone seems to not be able to charge the battery

Were you able to get this resolved? I have a xt1095 doing the same thing when I flash a stock recovery. Just shows the android guy and just stuck at erasing... When I flash TWRP it doesn't get stuck at the "erasing..." anymore but just boots straight into TWRP.
Sorry for the late response, I missed the notification on your message.
I wasn't able to fix it, returned it to motorola.
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.

I'm exactly on the same boat. Were you able to fix this problem?

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.
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.
Hi guys,
So I had a stock T-Mobile LG G4 H811 that I had unlocked and booted into twrp version 3.1.1-1-g4. I wasn't able to actually flash recovery of this .img becuase of a write failure. So I booted into it instead and then installed it from within twrp into the recovery partition. The actual stock software was the ORIGINAL original, which I think was android 5.1.1
From there, I cleared the cache and delvik cache and installed the G4-H811-10N-xTreme-2.0 Rom. Now, I can't boot into recovery mode anymore, and all I get is the bootloop.. but it's not dead yet because it's a software issue on my part and not a hardware failure.
Any advice on how to get it to recovery mode or at least so I can boot into twrp somehow to try and get this fixed? I tried Power+Volume Down and then let go a sec and Power+Vol Down again and it won't work at all. Just goes straight to bootloop.
Thanks in advance.. I know I screwed up somewhere.. just so many loopholes, it's easy to miss.
Best,
Johnnie
Got somewhere, still broke
Well, somehow I managed to boot into recovery mode only 1 time and installed the stock Tmobile rom. It installed, but now I get a white T-Mobile screen on boot up and it stays there. I tried using the LG Flash Tool 2014 and the stock T-Mobile H811 10N firmware for T-Mobile, but all I get is connection to server errors and the software won't install to the phone over download mode. Anyone else have this problem? I've been trying to figure this stupid thing out for 6 hours. Also, I'm wondering if installing the stock firmware caused the original recovery partition to go back to stock too which is the reason I'm no longer able to boot into recovery mode? It just doesn't recognize it. Power+vol down and then vol down doesn't do anything.
When using the LG Flash Tool 2014, all I get is Connection to Server Failed, Try again. So I do, and nothing. It fails at 9%
Thanks.
