[Q] Guys, please help

Okay, maybe starting a new thread isnt the best option, so sorry, but i really have no other option, i have surfed through the forums to no avail.
My friends G2 (D802 32GB) arrived with stock firmware V20B, and there were some problems, so i tried updating it to V20D Using the following kdz method.
http://forum.xda-developers.com/showthread.php?t=2432476
But i had rooted the phone on V20B (and im assuming thats why ) I lost download mode and recovery mode, when attempting to go to download mode, it goes to fastboot mode, so i used the following method to reflash the download mode
http://forum.xda-developers.com/showthread.php?t=2477595
I succesfully did revive the download mode, and attempted flashing through kdz again, resulting in being able to go to recovery and download mode (The download mode said rooted, i dont know why, shouldnt reflashing remove root? (CSE flashing)). But the phone was stuck on the Lg logo, so then i attemted the tot method, in which the update fails, something to do with Fota, i couldnt get it to work, so then i tried Flashing the V10B(Which was stupid of me) through the kdz method, and then, after flashing, the recovery was there (it was a bit different than the one after flashing V20D), but then, Its stuck at download mode, the download mode keeps loading forever, and also, no drivers are detected by the pc. (However, connecting normally gives USB composite device ) and i dont know how to proceed. I did my research and found nothing that helps me, im scared that the phone is already beyond repair, so yeah, i would really appreciate your help
As you can see, im a bit of a noob, so excuse my ignorance.
Isnt there anyway i could force fastboot mode?? or maybe some how use adb? The stock recovery is accessible, is there anything i could do?? maybe install a custom rom somehow or something??
Again, sorry, I just hope the phone can be unbricked :|
Thanks

LG G2 Bootloop Bricked - No recovery or Download mode

Hi guys, I might need some help or a walk through here, I might have bricked my phone. I stump-rooted my phone ( 4.4.2) and installed TWRP Recovery 2.8.1 initially , Installing SuperSU which patched my sdcard and rebooted causing my phone to get stuck in a boot loop giving me no access to download mode, just recovery. From there I tried to install Cynogen mod 12 in TWRP recovery to fix the bootloop but any attempt at flashing gave me an error "error executing updater binary in zip." So I extracted the folders and flashed the 2.7.0 recovery.img which sayed it worked but now my phone is still stuck in boot loop, no download mode and when I try to enter recovery I get stuck in fastboot mode with port change errors. I took some screenshots so it would be easier to help me out. Every time I plug in the USB I get the following errors, the screenshot is from continuous attempts
I have the mini sdk installed and Koush drivers. Device manager does not recognize my phone anymore but it does come up under Fastboot Interface
Any Help would be greatly Appreciated
Because I'm a new member I can't post screenshots so just add an h infront of the links.
Thanks in advance for all your help

Can you please explain how to do that WITHOUT entering download mode?
Maybe LG Flash recognizes your phone and will do the job.
LG Flash does not recognize my phone at all. http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 Do you think this method will work?

I will lose all of my data :(

Hello guys! I bricked my device, so it doesnt boot right now. I was on Cloudy Flex 2.8, then I wanted to flash Cloudy G2 3.3 (G4 ROM), but my phone was bricked. I wanted to solve these problems with SRK Tool. I did this option there: Unbrick - qhsusb_bulk 9006 (No Recovery Mode,No Download Mode).
Now, I can enter download mode, but afraid of entering recovery cause I think custom recovery lost, that's why If I try to enter recovery device will be factory reset. PC doesn't see my G2 Device gets "Security error" when boot. So, I dont know what I must to do. Want to back to stock but If I used to flash stock roms with kdz or tot methods after I must do factory reset And I don't want to do it. How can I backup my datas right now? And can I rescue my device without flashing stock Rom? Thanks in advance! Regards!!!
OMG Noone can help me :crying: Please, help me friends!!! I cannot do anything right now
