i have the h918 i rooted and flashed a deodexed stock rom.
no problem
today i got an ota update and i read somewhere use flashfire to retain root
it fail and restarted.
i had system but no recovery upon reboot.
i tried to flash a .tot file using uppercut/lgup and that failed leaving me in "bootloop"
i boot to download mode every time.
HELLLLP PLZZZZ
Instead of tot file try flashing the latest kdz

Have you tried power on and volume down to go through the factory reset screens.
A bunch of us had this problem and it was because an update downloaded on it's own and the bootloader snoops it out and forces recovery to boot.
Just do the volume down + power button - as soon as you see the lg logo release power only then immediately re-press power and continue holding power and volume down until the factory reset screen pops up. Select yes and yes, (don't worry - if you have twrp recovery it can't reset). It will boot you into TWRP and I'm pretty sure it will delete the update files in fota folder.
In TWRP select reboot - system and it should boot normally like nothing happened.

I realize your rebooting to download and not recovery - but I have a good idea that the above might just work for you as well. If not - just use adb to push twrp recovery to the phone and if it bootloops twrp - try above post.
Above is correct
You can also try to use fastboot
Fasboot erase misc
Fastboot erase fota
Then fastboot flash recovery recovery.img
Replace the last part "recovery.img" with the twrp image name or rename twrp to recovery.img
Once done then pull bat. And do above button combo to get into twrp

Hello.
Recently I installed this...
http://forum.xda-developers.com/showthread.php?t=1389394
...and I stuck on boot loop.
So angry of this stuff,however there should be a way,how to wipe data using recovery.
Actually I did the full wipe,but no luck. Boot loop is still present.
What's worse,I am not able 99% of time to enter recovery. Is there a way,how to SURE enter recovery? I hold buttons as I can,1% of attempts I am luckily entered there.
Another thing: If full wipe doesn't help,is there a way to reformat stock ROM or do I need some custom ROM to install?
Thanks.
anyone!!!
I have same issue. Need to install stock rom and adb not recognized. Wish there was some way to recover data too as I had some pics on there (yes I'm an idiot for not backing those up)
Hi.
I was using RR v22 and decided to flash stock kk2 rom via Odin.
It was all right but now my phone keep boot looping.
I can enter download mode.
What should I do?
Thx.

I tried home + vol. up + power to enter recovery mode and it worked (couldnt do it earlier)...
Then I full wiped and now I have my Note back!
Thx anyway!
last resort method.
enter download mode. (remove battery - use the 3 button combo vol down, home, power - reinsert battery) (easier if you have usb jig)
use pc-odin to flash stock rom.
Hi,
I can't boot into recovery using vol down+power but I can boot normally into OS and from there I can boot into recovery through ADB or third party apps.
I was trying to update my OP2 with new OxygenOS 3.0.2. As my device was rooted so I had to do it manually using TWRP. Till now I was able to boot into recovery by vol down+power.
Before flashing I wiped everything(dalvik+cache+system+data), rebooted into recovery and flashed the OOS3.0.2 full ROM. At this point the installation was successfull but I was not able to boot the OS, it was stuck on the loading screen. After several attempts to boot OS, I finally tried to boot into recovery to flash again, but I was unable to. When I press vol down+power for few sec, the phone switches off with a vibration.
Later I found out that I was supposed to use a modified TWRP. So I flashed the modified TWRP via fastboot and flashed the OOS3.0.2 full ROM again, Now I can boot into OS normally but still I cannot boot into recovery by vol down+power. But the interesting thing is that I can boot into recovery through ADB or third party apps.
I tried flashing the TWRP recovery again with no luck. I thought this could be a problem with boot.img which is contained in ROM itself so I also flashed the ROM again with no luck. Also I am absolutely sure that this is not a hardware issue with by volume buttons as I can use them properly when I boot into OS.
A quick thought, is it possible that the boot.img of the ROM itself is broken? Seems unlikely as I am not seeing anyone else having this issue. But if it is, is it ok to flash the boot.img from OOS2.x version ROM, will that be compatible? Just wanted to be sure before doing this.
Any other thoughts are welcome.
Are you used this command for flashing twrp??
fastboot flash recovery recovery.img
You should add "flash", otherwise it won't install twrp in your mobile
yes I used that command only

After flash recovery use this command it will help to boot in twrp "fastboot boot recovery.img " without quotes
yes I know that, thats how I booted into recovery from fastboot for flashing the ROM. But I should be able to boot into recovery by vol down+power. That is why I posted this question.
Will you please send me screenshot of cmd?? after flash recover
Hi,
I have a H918 its not booting into download mode it just reboot continuously
I can get into to fastboot but not download mode no matter how many times i have tried this it doesnt work, i used a different battery.
From fastboot mode i tried flashing the recovery img i get an error saying remote unknown
Please suggest if there is a way to fix this phone any help would be much appreciated.
Fastboot IS bootloader...
i mean download mode not bootloader sorry for the confusion
With your device powered off, hold vol up and then plug it into a computer. That should bring up download mode
i tried but it shows download mode briefly for few seconds then it tries to reboot and repeatedly reboots i have done a factory reset but nothing really works
It can only boot into fastboot mode nothing else, after factory reset it will get stuck on the LG logo and will not boot
Bump
You flashed a modified boot, laf or recovery without unlocking your bootloader. You can TRY doing a fastboot oem unlock while in the bootloader, but if it fails, there is nothing you can do to fix your phone.

My bootloader was always unlocked, I can lock the unlock and lock the bootloader but cant boot into the download mode.. looks like i bricked my device for good
Try grabbing system img and flashing via fastboot, or about img

*aboot
i tried looking for the img files i couldnt find it
So i wanted to finally install custom ROM on my LG G6 H870, needed twrp... obv, followed all the instructions:
adb devices - showed my device all was good
2nd: adb reboot bootloader
3rd: fastboot flash recovery twrp.img
4th: fastboot reboot + holding volume down and power button, on logo released power button and pressed it down again, finally got to factory data reset 2 YES options and saw the Teamwin bootup logo, but then phone just booted up normally...
5th: Tried to open recovery once more, but then it did regular Data erease.
What could be wrong?

I had exactly same problem when I did this = only Teamwin bootup logo and then boot into android (I hope your bootloader is unlocked first).
Solution was you have to use TWRP 3.1.1-0 and u get into recovery. I tried more versions of TWRP (3.2.1-0 , 3.2.2-0 , 3.2.3-0) but ONLY 3.1.1-0 works and I dont know why.
Anyway I got another issue after because I didn't want to install root yet (first I wanted to backup).
An issue was I got into restarting loop by installing no-verity-opt-encrypt 6.0 which should be a solution for boot into android without losing TWRP (considering to one walkthrough I found).
I was lost for a while but I found a solution = install another boot.img (in my case I installed one dm-verity or dm-verity & forceencrypt zip file - btw what is a difference between them?).
Oh wow.. Well thanks, ill try your solution as soon as i get time. Bootloader is unlocked indeed, used latest twrp. I'll try 3.1.1-0.
@ Razexay
that happened to me also with Official TWRP take that from Eliminater74 that's where backup and encryption work with dm-verity & forceencrypt look here in the forum everything is well described
