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.

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 ?

Is your device stuck at lg logo? If yes, you need to flash stock firmware on your device.
I got this Korean F500l model so I tried root. I downgraded with lgup, but after it, it shows lg logo then black screen then one more time lg logo then android screen which shows when android update. I downgraded one more time and downloaded another version of it but its same. And in lgup, it shows the version as F500l21a. Is there solution for it?:crying:
