then i restart and i stucked into lg boot
i still can acsess download mode
Help please

Why did you wipe and format everything without flashing a new rom? Can you still access TWRP? If so, just pick whatever rom you want to flash and flash it.

Help PLEASE

Okay so i had a rooted 30f lg g3 16gb d855 and i went to use LG up to flash a new 30f kdz since i didnt want root anymore. Then i think LGup deleted the rooted android and i think only TWRP is left and i cant do anything, i tryed using LGup it wont find my phone i tryed to flash multiple zip files no luck it just keeps booting in TWRP and cant boot the phone. If anyone has an idea what to do please help me im ready to cry.
i am unable to mount cache or data(storage) when i try to wipe it?
SOLVED by using LG flash tool and flashing stock kitkat.

[<help me>] cannot boot in to recovery lg g3 f400s

i have a Lg g3 (F400S). Currently i am running on cloudy g3. i wanted to update to FULMICS 5.0 ROM. while following the instructions for the rom it was strongly suggested to update your TWRP. previously i had TWRP ver 2.8.2.0. so as per the rom instructions i downloaded TWRP ver 3.0.2.0 for f400 and booted into recovery to install updated recovery image. there i could not see the image button (The option in install menu which allows you to install .img files) in the install menu of TWRP so i downloaded the TWRP app from play store and after selecting the correct TWRP recovery image i installed it from the TWRP app. the app gave me a success message.
but alas now i cannot boot into recovery mode any more. it gives me
Boot Certification verify
----------------------------------------
secure boot error!
Cause : boot certification verify
----------------------------------------
fortunately i can still use my phone and my cloudy g3 rom is running without a hitch. i can also enter download mode successfully. the only problem i am facing is when i enter my recovery mode
P.S i made a backup of all my partitions from TWRP before proceeding with any thing and i still have that backup.
if any of you can help me correct my recovery.

Problem with recovery in lg f240k

Hello guys, I have a problem with my phone. I need to install a custom recovery in my LG F240k but when I install one recovery my phone brick. I tried to install twrp and philz recovery but when I install and I restart my phone, my phone only start in recovery mode or show me the error "error boot certification verification". I think the error is because I don't have the phone with bootloader open and also I need help to unlock the bootloader. I use the app "freegee" but i don't have the model e980 and this program show me a error. I have LG F240K model, android 4.4.2 and software version "F240K20H". I don't use android 5.1 because the recoverys and tutorials working in android 4.4 and when I install custom recovery I make the wipes. Also I need help with the vibration of the phone, I can delete complety the vibration of my phone, editing the build.pro maybe?
Someone help me? Thank you for the answers :fingers-crossed:

You're on KitKat, FreeGee isn't working with KitKat aboot and never will. Use GPRO recovery apk from forums (if you can't find it in forums, tell me, I'll upload it somewhere, but really try finding it on forums first) to flash compatible recovery, then flash from freegee or simply flash twrp with flashify. Or even better, flash stock jellybean and use freegee on it.
About vibration issue, I don't understand. You want to completely disable it? Just go in notification settings and uncheck vibrations and haptic feedback everywhere you see it.

LG G3 F400L those who have problems installing android 11

Hi there I created this thread for the people who have a hard time with their lg g3 f400L
I know this issue is kinda late in 2021 but I hope I can still help someone.
So lets start
I'M NOT RESPONSIBLE FOR ANY BRICKED DEVICE! YOU HAVE BEEN WARNED
I just want to share this for those who have F400L specific device!
There are many problems that I faced when trying to load a custom rom android 11 in my device I always get the error of boot certificate error or something or the twrp doesnt recognize my phone as f400L when trying to load a android 11 custom rom because it needs to have the latest twrp in order for it to continue the installation of the rom. Tried every single Official TWRP and nothing seems to work so I tried using unofficial TWRP.
So this is my solution
1. Restore to kitkat.tot the name of the file is this "LGF400LAT-00-V10a-LGU-KR-MAY-18-2014-0" for f400L use LGUP for this (I haven't tried using lollipop for marshmallow it's a nono I get the MISMATCH SIG LEN error)
2. root using purple drake lite
3. once rooted install twrp using the bumped! the method in xda "twrp-2.8.0.0_f400-signed.img" using flashify or any other method you want.
4. download "flashable-twrp-3.3.1-20200315-f400-themed.zip" from "https://forum.xda-developers.com/t/recovery-3-3-1-abandoned-twrp-for-lg-g3.3813552/" scroll down to the download section and click the "MEGA (recommended)" link there you can find the zip file
5. once downloaded put it in your sd card boot to twrp and locate and install the "flashable-twrp-3.3.1-20200315-f400-themed.zip"
6. once installed reboot to your recovery using twrp
7. if it boots to a black screen remove the battery and try to access your recovery mode
8. if it boots to recovery then you are good to go! (F400L method of recovery is holding Volume down + Power button once LG logo appear let go of the button and immediately press the volume up + volume down button and a factory reset image will appear just press yes and yes and now it will boot to a red twrp)
PS: my lg g3 F400L is kinda tricky to boot to recovery so in order for the buttons to work I press it to the edge as hard as I can, if your lg g3 is like mine send me a message I will help you.
9. In twrp wipe system, cache, data, dalvik cache
10. install any android 11 rom or lineageOS rom
11. install android 11 gapps
12. wipe cache and dalvik cache
13. reboot!
And wait for it to load up mine takes about 10 mins or so.
I just want to thank :
HardStyl3r
I didn't know that the answer to all of my problems is only his unofficial twrp! The unofficial twrp is abandoned so I hope anyone out there can update it.

Thanks

Thanks for your detailed tutorial!
It works on my LG G3 F400s (after installed twrp 2.8.0.0 it became typical F400)! And I can have a taste of Android 11 on my g3 finally.
I follow all your steps expect step one. (My phone was still Android 4.4.2)
For those whose devices are different from F400l can follow all the steps expect changing the file (.tot) from f400l to like f400s or k at step one.
Thanks
