Hello all.
I was charging my lg g3 Singapore version. Suddenly it reboot and cant boot up anymore.
Unrooted. Never install any tweak apps. I try hard reset boot back to same picture as attached. Any solution... I tried download mode cant get to firmware update page. Installed drivers on pc already. With lg pc suite.
Help!!! My LG G Pro (F240K) stuck in the LG logo.
I follow the link below to flash the Lollipop 5.0.1 for LG G PRO F240 K into my LG G Pro(F240K). It finished the update process but now stuck in the LG logo screen. I remember my original version is 4.0.x.. I didn't have a backup of my original kdz....
I just root my device but never flash any Rom before. Is there any problem to flash 5.0.1 into it?
I tried to download a Rom F240K10r_00.kdz to flash again. But still stuck in the LG logo. I don't know what to do now.

"CSE Flash" will wipe all data in your internal storage.
I also had bootloop when downgrade to 4.4 from 5.0 with "Normal Flash", then I tried "CSE Flash" and It worked.

LG Optimus G Pro E988 Bricked Issue
Hi there my friend I have bought LG Optimus G Pro E988 recently but 4G LTE was not working on it so I tried to update its ROM and while doing it unfortunately it bricked. Now when ever I tried to power on my phone it shows LG sign and reboot again and again and nothing pop up i tried many things with download mode but it does not work and it is also not going in recovery mode and I cant find its bootloader. Can you please help me this
Hi all,
Still confuse and not understand. By yesterday night after downgrade my LG OGP F240l (U+ Korea) and successful with Sim Card Disable I leave my OGP on desk until morning and low ?Then i try to OFF then pull out the SimCard and try insert the Simcard and ON my OGP fortunately thw simcard read and have signal but Service disable on screen. I have hope when the signal show. Just check the hidden code set the network show LTE. Try to WCDMA/GSM reboot the phone the issue FIX. Now my OGP fully work with Kikat and try to Flash again to Lollipop and successful my simcard fixed. Correct i am using CSE to flash and its work. I think the phone baseband installed try to stable and optimize it self first to network on my country.
Now my OGP running Lollipop (no root).
Regards,
Hey I have the same issue, not yet solved.
I was on F240L30C Lollipop and Want to Downgrade Because I am facing Screen Wake up issue (no issue when i was using KitKat 4.4.2).
I have downloaded the f240l20c_00.kdz firmware from pan.baidu.com , but after flashing my phone gone in to loop (Lg logo then android animation icon processing then reboots again)
I can't enter the recovery mode as well.
I have tried using CSE Flash but same loop again.
Can anyone Help ?

hey guys, I updated my G3-D855 to V30C through lg pc suite, and after I updated it, I started getting bootloops a few times in a week, the phone just shuts down and restarts, I came from V30B (KDZ MANUAL UPDATE) to V30C and this happened, I did factory reset (with LG BACK UP and restore) and it didn't solve the problem.... Plus I got a huge battery drain which I didn't have before....(I am not rooted I have to say)
any ideas?
thanks

I have got the same problem here. Reinstalled the latest firmware and while it looks good for a while, the bootloop keeps coming back.
Hi,
I tried to upgrade my LG G4 H815P with this thread:
https://forum.xda-developers.com/g4/development/h815-nougat-stock-locked-bootloader-t3709119
The process with LGUP was ok (upgrade mode), but after the first reboot the phone stucks on LG logo, so I tried to use refurbish mode but the process throws a error 0x2000.
I tried a lot of solutions but the problem continues.
Maybe you know a tot file with android 6 to restore my phone with LGUP?

Seems like the restore only works with H81520p_00_0314.kdz
Solved!
