First i would like to say hello, second the issue: So i followed this tutorial: how to downgrade my 6.0 to 5.1.1 (official). [Reason is for root] (it was on droidpinoins)
So i checked everything, and it seemed all ok. (all requirements)
Than i downloaded the OPEN European rom (official), and i followed the rest.
LGUP did it's magic (I did install dll first) [spoiler ruined it], after the process it said it's all done.
I see my phone resets and it gets to "LG life is good'' loop (but it's not the same as others loops that you can find in youtube video) [it's the second animation after the first one]. And now is in the vegetable state.
And i have tried to do as suggested in forum, to turn the phone in recovery mode. But it failed, the phone gives me a small vibration and ignores the recovery mode.
So any ideas on how to fix this or wipe the current rom?!

Hello
I recently installed CWM in my LG Nitro HD after rooting. The thing is that it' s now stock in the LG logo. This happened after installing "kernellpan1c's" ROM. I follow instructions and I did not factory reset the phone. The phone was working fine when I went to sleep, but when I woke up, the LG logo was flashing . I went to the only ATT warranty center in San Juan, PR, but the guy was smart and knew that I flashed a ROM
I followed the guide about fixing Nitro's briked statet, but as I follow instructions and the threat, I got confused and I wast't being able to complete follow the instructions because some steps were not giving me the same results as the guide posted.
Can sombody post a complete guide "for dummys" like me, about unrooting and or flashing stock ROM with adb in Windows? I think this guide will be super helpful for me and other people with future trouble with the Nitro.
Please help !
Thanks ! !
You would have better chance get an answer by:
1) replying to the appropriate topic: [Solved] Unbricking Solution for LG Nitro HD | Confirmed Working on Bell Optimus
2) provide more detailed information about what you've done, and what you got. ("some steps were not giving me the same results as the guide posted.")
P.S.
This post will probably be deleted, so don't waste your time replying here, do it at the topic mentioned above.

OP, can you still access CWM? If so, follow these instructions to format data safely:
http://forum.xda-developers.com/showpost.php?p=22533342&postcount=235
then re-flash the ROM (wipe cache, wipe dalvik-cache, format /system, install zip)
No, i can't acces the CWM.
Flashing the SU-640 rom:
1) Put your phone in download mode: power off the phone if it's not already, unplug the usb charging cable, and simultaneously hold the volume up button and plug the usb charging cable back in. DONE
2) Open up UpTestEX_mod2_marwin. (If you know what you're doing, I've been told you can use KDZ_FW_UPD_EN as well, but since I didn't use it, I'm not going to discuss it) DONE
3) Hit the folder icon next to the "Select kdz file" line and browse to the SU-640 v10f_00.kdz DONE
4) Select "CSE web upgrade test", a new window with some options including an "Upgrade Start" button should appear. DONE
5) Take a deep breath...there's no going back Press "Upgrade Start".
6) At this point in time another dialog box will appear asking what country and language the LG Mobile Upgrade tool should use. Since this guide is written in English, I assume you'll want to change it from Republic of Korea to All other countries and Korean to English. This affects the language that output messages are displayed in in the LG Update tool only, it doesn't affect anything with the rom (that'll be all Korean on initial startup lol). THIS IS THE PART WHERE I GOT STOCK BECAUSE IT WON'T OPEN THE LANGUAGE OPTIONS. IT WILL JUST OPEN THE LG MOBILE SUPPORT TOOL
7) The update tool will proceed to flash your phone, but it should never complete "normally" (mine never made it past 4% according to the tool and other users have reported similar behavior). However, your phone should reboot once or a couple of times and then just be sitting idle waiting for you to go through the setup wizard. At this point, just kill the LG update tool process in task manager, don't wait for it to complete because it won't.
Okay, my phone is LG E988, and i followed the guide: http://forum.xda-developers.com/showthread.php?t=2460859
I got until the TWRP part, managed to flash TWRP, and that is when the nightmares came out.
I used ROM Manager from the app store to get into recovery mode (With TWRP as recovery).
First try, i got into TWRP recovery page, but the touchscreen failed so i pulled out my battery and restarted the phone.
Got back to android screen, then wanted to go back recovery mode via ROM manager again.
This time, when i reboot into recovery, i got into CWM instead of TWRP. So i select "Reboot to system" to restart the phone.
Now is where all the **** starts. I'm stuck at the LG logo page with the message "boot certification verify".
Restart many times by pulling battery out but no avail. Then i went to factory reset the phone. After confirming factory reset, screen blacked out for a few sec then i went back to CWM. I cant find any backup either.
Tried all fixes from the forum but all not working. Cant extract .dz & .dll from .kdz because it cant (becomes corrupted).
Anyone can provide me with E988 Singapore .dll and .dz !!! NOW MY GOAL JUST TO MAKE IT BACK TO STOCK!!!
HELP ME FIX THIS PLEASE. MY DAD IS GONNA KILL ME !!
Note: Some might blame me for my own fault to tweak my E988, but someone said that customs for E980 can be used for E988. Please help
Edit: Still need the .dll and .dz please
Edit: I found a solution. I was able to flash the older stock rom back on and was able to root from that installation.
Device: AT&T D850 10d
OS: Android 4.4.2, Kernal 3.4.0, Build KVT49L.D85010f, Software verstion D85010f
I've only had the phone for a couple of weeks, so I'm assuming it has any recent patches which may have caused issue. I've looked around, but I haven't been able to find this exact scenario, though I've found similar for the g2.
I first tried using Towelroot, but got the error that the device wasn't supported and so I searched around and found this tutorial (though I'm just now seeing that it is for T-Mobile devices if that has any bearing). I got down to step 14 at which point the device rebooted but stayed on the Fastboot screen only displaying:
[750] Fastboot mode started
[840] -- reset --
[850] -- portcharge --
[1010] -- reset --
[1010] -- portcharge --
[1220] fastboot: processing commands
and it doesn't progress from here.
Now the device will normal boot just fine, but anytime it boots into the fastboot it will stick at that screen. So if I reattempt the steps of the tutorial, I don't get past step 7 without getting stuck on that screen again. Also, I tried to do a factory reset and when it restarted, it just said "Fastboot mode started".
I've downloaded the files to attempt these tutorials:
- [Guide] LG G3 Stock Firmware (Go Back to Stock)
- Official bootloader unlock procedure from LG AND the one that works for everyone
- How to Unroot/Unbrick LG G3!
but I figured I would hold off until I got some expert input on the situation as I'm not even sure if they would help.
I just got the official update to Marshmallow and I decided to just do it since it is official. It downloaded and then installed. Then it rebooted and showed that "apps are being optimized" screen and after that a bootloop of the lg logo. Rebooting doesnt work only if I take the battery out but afterwards there's still a bootloop. I also didn't do root or anything else to my device. I can not enter download mode or recovery either, but honestly idk if it has worked before.
Can anyone with probably similar experiences help me? Thanks in Advance from Germany

I have exactly the same issue. I have a German-bought LG G3 d855 updating this morning to Marshmallow. It is now caught in exactly the same boot loop. I get the LG logo, for a few minutes (the brightness changes during this time) followed by the "Android is updating..." app optimization screen which optimizes my 44 apps before going back to the logo in a constant cycle. Then my 44 apps get optimized yet again, and on it goes. I can't enter recovery, none of the button combinations has any effect. Phone has no mods, and was working fine before this.
Does anyone have any ideas?
Hi,
Similar issue here, my phone updated today (also no root, no mods) and for a couple of hours everything worked fine (just some missing apps after the process, but ok), then I went to flight mode and back and then it started with the reboot loops.
The reboots on my phone happen after some seconds in the home screen, so I have time to try to set it in flight mode again, and in some cases, after this it stops rebooting, but in flight mode, with no connections at all.
I'm trying to remove things to avoid doing a factory reset by now, removing cache didn't help...
Is your phone rebooting also after loading the home screen? or it just loops in the LG screen or in the apps update screen?
Hello,
I had the same problem. Just hardware reset the device and the device will continue from optimizing the apps
Instructions on how to hard reset see the video find on youtube "How to Enter into Recovery Mode on LG G3!"

You can try "normal flash" at the first time, but if it doesn't work (for me it doesn't work) you will have to choose "CSE Flash" and it should work. But you will loose your personnal data. So be strong.

Bro Thank You so much ive been searching for solution the last 2 days and you finally saved my life Thank you Man !
i have the same problem....after the stock firmware has been restored,what method is used to get the proper working marshmallow upgrade?
I went from 5.0 to 6.0 using the LG PC Suite.
0 problems, 0 reboots, quick and fast. Did you update through OTA?
yes i did but still boot lop............is it the battery?
so ?
Same problem here, did you find a solution ?
New G3 from LG but back in bootloop after 24h of use.
Thank you.
I got the exact same issue, neither hard reset or flashing firmware works. Is there any other solution or should i start looking for a new phone?
Edit: Somehow it works just fine now lol. Tried flashing it like 3 times and hard reset twice and now after an hour of constant optimizing apps bootlopping i pulled out the battery for like the 100th time and now it works, what the hell. Looks like my G3 will die soon tho haha
Hello, first of all I want to apologise if this problem was already discussed, I tried searching in threads and also using the old friend google, but found nothing related.
So, yesterday, I managed to flash the a.o.s.c.p cypher OS (https://forum.xda-developers.com/g4/development/g4-cypheros-t3680102), Oreo version, and after I tried rooting with Magisk I've got bootloop issues with the rom. After this, I reinstalled the zip file and it managed to go back to the OS, but every installed app would crash when tried to open. Because I did not find my backups (not too organised, I know) I tried flashing through LG UP the "LGH815 EU Nougat 7.0 BySezerSimsek.tot" file I had downloaded on my laptop, unfortunatelly, after 10~ seconds, the download mode just restarted and since then (though, it was doing this before I tried to flash with LG Up, but I thought that after I start flashing it will not reboot...), everytime I try to boot my device either normal or to recovery mode, it goes automatically to download mode, where it stays for 10 seconds and then reboots (So I'm not able anymore to use LG UP).
Also, tried LGMobile Support tool, but because I cannot keep the phone in download mode more than 10 seconds, it fails to do anything, it finished to download a firmware for it, but was unable to flash it.
Is there any chance I can "revive" it? the battery was about 50% when I started the first try with download mode, so now, it should be around 20-30% I guess.
In Download Mode, in the box, it says:
633A B49
Modified
P.S.1: After reading some more threads, I found that some people were stuck at 9% while flashing with lg up, but for me, as I said before, the download mode just keeps restarting no matter what I do with it ( even if I just leave it not connected to the pc)
P.S.2: After some more flashing with LGUP tries, I came to conclusion that the download mode restarts after ~17 seconds, and now, in the rectangle it says:
633A B56
Modified
P.S.3: I have been trying to flash "Europe H81520D_00_0115.kdz" and sometimes, if I get the timings right, I can get up to 25% (it restarts at 9%, ~19% and then 24-25%, so, it doesn't always give error after restarting and reconnecting to LG UP). I used the .dll extracted from .kdz file.
Hello, i have the exact same problem as yours with the same custom rom.
My phone stays around 20 seconds in download mode, i can launch LG UP to flash H81520i but 20 seconds is just not enough to flash the LG G4 firmware AFAIK.
I did see that there are some ways to launch the Qualcomm emergency mode but we'll need to disassemble the phone to short two pins to force it to boot in this mode.
I finally found the solution ! Follow this tutorial : https://forum.xda-developers.com/g4/general/guide-proper-h815-unbrick-qfil-files-t3709212 You'll need to disassemble the phone in order to do this tutorial, after you've done the emmc flash you will need to reflash a rom with LGUP.

Thank you for the reply.
I already fix my G4, but unfortunatelly I do not have like a detailed fix because: I went to a "Phone repair shop" and I left my phone there for one day. As I said, before I was not able to boot into recovery, the phone was restarting in download mode after ~17 seconds, and I had no idea about the battery percentage.
The next day I took back the phone and the guy there told me that there was not much he could do, but when I got home, the moment I tried to boot it, it went to recovery mode (twrp) where I tried to install a ROM (I forgot which one, but it was a .zip) and it failed to mount /cache. After that, I tried booting into download mode where it stayed for as long time as I needed without restarting. I was trying to flash 20D version (failed at 25% everytime) until I found this thread where the advice was to use the 20P version. After that it just worked fine.
So, I have no idea what did the guy from the "repair shop", I don't now if it was just related to my battery "running out of juice" or maybe he used any other "magic" box with tools for android smartphones (I've got back my phone with ~60% battery).
Also, before I went to the repair shop, I tried a method I found on xda, unfortunately I could not find the link right now, where I had to format a micro sd card and kind of "flash" (it's not actually flashing) a file to the SD card, put it inside the phone and just boot into Download mode (I'm not sure if it affected somehow the state of my phone)
