Hi,
I have problem with my LG G4 (H815). I has stacked at boot screen and sometimes it is able to boot to home screen but after a few second of work, it restarts again. Few days ago the situation was the same but after a few attempts it booted normally. I can normally enter recovery mode and download mode.
Has anyone idea what to do to recover data (photos) from it?
I will probably try to flash stock firmware via LG Tool but I don't know which version is now installed and I cannot find a proper kdz file.
Can anyone help to find a proper kdz file for this phone? and give a link to quide how to flash phone without wipe data?

I don't have TWRP installed. If I have and access to download mode and stock recovery, is there any method that let me install TWRP to recovery data, if I can't boot to home screen?

o when you mentioned recovery i wasnt expecting the stock recovery.. so does your phone boot.? does it have the infamous bootloop when you see logo and it reboots again into a bootloop sometimes optimizing apps then reboots..?
if so i think the only way to recover data its to use the freezer method.. search for it... sorry
if its bootloop then its hardware and needs to be sent to LG just make sure the moisture strips arent allow to get losit or water.
is there any way to force bootloop???? with a kdz file or changing something with root permision ??? i need to send my phone to the SAT

i would say strees the phone play heavy games under sunlight.. another way maybe to flash KDZ let it optimize then reflash again dont let it rest optimizing gets very hot..

You need to have an unlocked bootloader to do so.
What are the first 3 digits of your serial number (sticker behind battery)
If it starts with 5xx your chances are good to have the boot loop issue which is hardware related.
Try the freezer method to recover and send the device to LG for replacement.

So, today I tried to root and unlock my device, it successfully rooted but after unlocking through FreeGee with TWRP 2.5.0.0, I turn OFF the device and it cannot get past the LG Boot logo. I have all the latest updates, firmwares, etc.

Thanks for the reply, really appreciate it. I wanted my phone to be rooted and unlocked tho, and TeenyBins is suppose to do that. But I do not understand the instructions, and how I understand it is-- Loading the downloaded .bin file in LGNPST? Is that correct?
First you must download the LGNPST program. I can't link it to you because we are not allowed to link the program. You can find the LGNPST link in the IRC, so ask there and they will link you. (make sure you read the steps that are given to you in the IRC on how to properly set up LGNPST)
Once LGNPST is running correctly on your computer, download the teenybin.
Select the correct .dll
Select the correct teenybin you want to flash.
Turn off phone. Connect phone to computer via USB.
Go into Download mode on your phone (Press and hold Vol Up+Vol Down+Power). Do this while phone is off and you will boot into download mode.
Now press start in LGNPST and it will flash the teenybin.
You will not be stuck in the LG boot logo anymore. I did these steps because I also was stuck a while back in the LG boot screen and the teenybin does help.

I've already done those steps and in completely stock Android 4.1.2 ZVB. I understand now that you have to flash the TeenyBin .bin file in LGNPST to unlock the phone, which I had trouble doing on FreeGee which led me to softbrick and go back to stock and to reset it. My question is, does TeenyBin file root your phone or do I have to root it and then load TeenyBin file on LGNPST to unlock?
I believe that if you're completely stock (non-rooted) and you flash a teenybin once you are in recovery. TWRP will root for you.
Don't take my word for it, but I believe that one of those devs that worked on the teenybin said that.

Back again and after 2 times of restocking with LG Tool. I followed this guide to root and unlock (http://forum.xda-developers.com/showthread.php?t=2050582). Rooting seems to work 100% with this guide but after unlocking with FreeGee, I shut down my phone and LG Boot seems to just be looping forever... SO, anyways, I am rooted again and wanted to see if using TeenyBins will unlock my phone... Im afraid of anymore bricks and possibly a permanent one. Should I go flash it? Also I'm new to the rooting and unlocking thing and I have a bad English so please bear with me.
your issue is you need to "SBL unlock"
so you can either use TeenyBin AltBin or just go all the way back to stock.. then using FreeGee app.. open it.. hit menu button > select "sbl unlock" > get code > enter code > then unlock like normal.
if you want to use teenybin but plan on staying stock... id suggest "TeenyBin ZVBin". the other teenybin files are more for fixing softbrick/unlocking.. and then getting u into twrp recovery to flash a custom rom zip.

all i wanna do btw when I unlock is load this rom (http://forum.xda-developers.com/showthread.php?t=2219393) please help and guide me to unlock and after that loading the rom is up to me. I've loaded a rom before on my first gen kindle.

i was under impression u couldnt boot.
if you want to use the rom you linked...
download the rom zip AND gapps zip... stick them on internal sdcard... power off phone and boot into Download Mode... flash LS970 TeenyBin AltBin. after you flash teenybin altbin your phone will reboot at 67% then probably get stuck at boot. power off and boot into fastboot(vol up + power).. then boot into recovery from there.
once inside twrp recovery.. do a factory reset.. then flash rom zip.. then flash gapps zip... reboot.

teeny bin rocks
Teeny bin saved my booty twice it rocks
:victory: The application helped restore my phone back to normal after I used the orginial stock bin, but after I used the teenybin and flashed Vanilla Rootbox I noticed my battery life drains a lot faster than usual. My usage on the phone is REALLY heavy like, it would last up to 6 hours and I recharge it when it hits 60% while I'm in class, (I'm a senior at high school).. I can admit I mess up my battery life. Is there a way to fix it?
i accidently enabled some option under development tools (something about dual display, and i pressed in 1080p option) and when i did that the hole phone froze and i restarted and now it keeps getting stuck in boot.
But the hardest part is that i can't get in to CWM i keep trying but it just boots over and over again. I even tried to install another CWM with odin but no luck there still the same.. cause i have a backup but i can't reach it.
so if you guys don't know how to fix it could you tell me how to wipe all so i can re-install cm10.2 and then just restore from the backup i did before that's sitting on my ext.sdcard
:c

Some suggestion
A) Try to download full wipe stock rom which you will get 5 files.
Or
B) flash twrp thru odin pc , boot into it and perform full wipe.
Or
C) Download bootloader and flash it thru pc odin and full wipe rom as well ( dangerous)
Just for your information, please use search function to find the related thread( mentioned above) and understand it before you proceed.

Hi everyone.
I'm so frustrated for a week to get get back to Stock Recovery Menu from CWM Recovery. The problem is, I want to restore Stock Firmware for my LG Optimus G E973 but it won't work unless I role back to Stock Recovery Menu. I've been searching around for it but no luck. Now the only hope is to get Stock Recovery image and push it into the phone and I think the only ways to get it is, someone backup Stock Recovery from the same phone model or extract it from original Stock ROM image. I failed to do so. For the convenience to download the KDZ file, I uploaded it to Google Drive with the link below. I bag you, PLEASE, help me get Stock Recovery image from the .kdz file I uploaded for you. I will wait for your response every seconds and thank in advance.
https://drive.google.com/file/d/0B8G245x5wYw2a1VhTjVZQXdqOTQ
Why not just flash back the official kdz? The download mode works regardless you have stock recovery or CWM.
I did. it won't work. I used KDZ_FW_UPD_EN with .kdz file while putting my phone in Download Mode. Then the program restart the phone to proceed the installation but CWM recovery appear instead of stock recovery and nothing happen.

You need to flash official full KDZ upgrade. What phone you have originally? F180 or E975? or some other? Wipe + Factory reset in recovery before putting into download mode. (The major nuisance with this set is all you can do is power button thingi and no battery pullouts.

Do you have acces to TWRP?? if answer is YES, then you can boot into it and use ADB commands on your computer to replace the file for the previous one.
If you can't use TWRP then you must use PC Suite and use recovery from error upgrades, this will flash your phone with your stock rom but won't gonna wipe your data so it's safe.
thanks guys! used the pc suit and solved the problem! thanks

I ran into the same issue. Phone is stuck in a bootloop. What is the process exactly? Since its in a bootloop my computer and my phone don't link. So I cant even get to factory reset. What do I do?

I ran into the same issue trying to increase my speaker volume and encountered a bootloop after a reboot.
I used LG PC Suite to recover but I was never able to connect properly, even with all LG USB drivers installed.
I resorted into flashing a stock firmware (10h) using the LG Flashtool and I was able to use my phone once more, but from a fresh install.
I will stay away from any sound mods until there is a permanent recovery I can install on my LG G3 D855

Try turning on your device on download mode before connecting to pc. You can follow pc suite or what @jtambis6 suggest. I recommend to try pc suite first.

The full story:
had xposed and snapchat installed.. and whenever i accessed snapchat the phone boots into the lock screen and once i unlock it boots back.. until i turn on airplane mode and then off later on .. it worked in making me to stop the bootlooping for the moment. so i thought to try to freeze xposed (since snapchat detects it) and then i ran snapchat.. and went into bootloop but this bootloop didn't even boot into the lock screen not even the system.
I was able to access TWRP recovery, so i tried to reflash the rom, twrp crashed, tried to wipe the data and everything that is causing the loop.. the twrp crashed and wiped only the system... then twrp crashed and now not able to make it load it crashes instantly.
the phone now can:
- access download mode (but not detected by pc).
- boot into the system but there is no system but it bypasses bootloop (when i boot in the system the phone is detectable by the pc)
- if i try to access the twrp it starts bootlooping fast
I tried the LG Flash tool.. to flash to stock... the phone is detectable when it tried to boot into the system.. but in download mode it is not... tried to change drivers or different drivers.. cables.. it is not detectable in download mode.
LG G3 D851
if there is a way to access the phone through the booting into the system ?

Ok i knew how to boot into the twrp.. i press volume down + power as if going into the twrp and i plug the cable into the phone (already linked into the phone) so i was able to access twrp in the log it says Failed to mount /system (invalid argument).
I wiped the data and system and flashed rom (fulmics) and was not able to boot into the rom .. it gave me the sign of flickering Led light but not booting the rom.. i have the stock " BIN_LGD851AT-01-V10c-310-260-JUN-20-2014-0_2.zip" but i guess not possible to flash it
