Softbricked H815 - G4 Q&A, Help & Troubleshooting

Hello Guys, I hope you can help me.
Think I softbricked my h815, I can't enter recovery, it stays on first boot screen (with bootloader unlocked message)
Only possible think is to enter download mode, but lg up doesn't recognize my phone.
Any ideas what could solve this problem?
Thanks
Edit: managed to get lg up to work. Flashed a kdz multiple times but ist still won't get out of Bootloop :/

G pro F240L stuck in Bootloop

Hi everyone!
I am starting this new thread with the hope that someone here will help me get back my Lg G Pro back. I have a korean variant of LG G Pro (F240L). I rooted it and then unlocked the bootloader with Feegee. After that i installed a couple of ROMs and all were well. then I tried this one ( LG_GPro_FinalZ_Lite_III_Mod_By_RadeonMaya ). When i rebooted after a successful update from sd card my mobile stuck in bootloop with the 4 colour dots logo turning in-out.
I tried to get back in to the recovery via key combo (Vol dwn + Home + Power) but the phone will just restart. also did a hard reset but nothing seems to work. Then i went for a KDZ flash but the problem is the "B2CappSetup.exe" wont download the mobile support tool.
Now I am stuck with a dead phone for the past 3 days. Any help will be highly appreciated.

Which version of Windows are you using? try using Win8 32bit, and follow the procedure in below link. Freegee cant be trusted, i did a factory reset on stck rom and after reboot i only saw CWM page on F240L, then i followed this link and revive my phone. And currently using LG gpro Final Z rom by Radeonmaya.

I am using W8 32bit. I followed the same tutorial and installed the Radeonmaya Rom and thats where i bricked my phone. If i could just get the B2Cappsteup working i think i can fix my phone. Anyway thanks for replying dude.
B2Capp will not work on proxies. Try using it on clean network.

I think that might be the problem as i am my university network which is proxy based. Will try on a clean network as suggested and post the update tomorrow. Thanks for a clue to work on though

[Q] LG G3 security error

Just got the phone today and successfully rooted it and I wanted to see what this xposed framework stuff was about I installed the experimental version (tbh did really read it was experimental it was on the front page so I thought it was alright) and when prompt to reboot I did, but now when rebooting I can't get passed the Lg secruity error screen I tried re-flashing back to stock using this thread http://forum.xda-developers.com/showthread.php?t=2799647 but nothing happens after I plug my G3 back in it just says ready is there any other way to fix this security error?
edit:found out that my model number is actually the f400s (sorry i'm a phone noob) for anyone else out there trying to find your phone model it's actually behind the battery

Again I ended up resolving the issue myself and I do not have a picture of the error but I can describe it. When booting my lg g3 the normal big Lg logo appeared then after a bit a smaller lg logo appeared with the words "security error" under it for those looking for a solution to that problem the thread in the op is the correct action to take to resolve the issue. Note doing that wiped everything on my phone which was not a big deal for me but I had to take my phone back the the carrier to input the configuration to access 4g lte again & it unrooted my phone.
i have this same issue can you tell me how you got around it?

jerimynal wiley the error you get "secure boot error" is caused by image you are trying to boot not being bumped or not properly flashed. I assume you get this error both while trying to access recovery and OS. If that is the case you should use this guide:
http://forum.xda-developers.com/showthread.php?t=2785089&nocache=1
to flash stock firmware on your device.
But if you have a case where you are able to access your recovery (TWRP I assume) you could use one of the custom images provided here: http://forum.xda-developers.com/lg-g3/development (assuming you have D855 version) . Flash them and use them as OS.
Thanks man. I actually could get into recovery so I just flashed another kernel
