[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

[Help] LG G2 bootloop, Only open in download mode, No recovery

Update,
I fixed this problem by using LGUP. My phone was refurbished (ls980) so that's why twrp didn't booted,
Hello,
I have a LG G2 d802 32gb variant. I bought it a week ago. I was running andoid kitkat OS (HK D80220C). It wasn't rooted. I tried to get official updates from about phone section but "no updates". So i decided to manually flash updates from a rooted recovery as i did in my LG G3.
First of all I rooted it by "IOroot". Then tried to install custom recovery by "autorec d802". Everything went good and autorec was also successful. I asked me to reboot into recovery, I pressed yes and then it took me to "fastboot mode". I tried to reboot into OS by pressing power button (As battery is non-removable). Everytime it rebooted back into that fastboot mode. This once happened with me on LG G3. So i tried to flash "laf" and "recovery" image and downloaded from here
http://downloads.codefi.re/autoprime/LG/LG_G2/D802/Stock_Firmware
I flashed them by CMD fastboot method. Now it stuck at "LG Logo" and download mode was also started. So i decided to install a stock rom by KDZ or Tot method. First i tried KDZ method. I downloaded stock rom "Hong Kong D80220C_00.kdz" which it was previously running. Also installed all drivers, downloaded flashtools2014 and connected phone while in download mode.
I started KDZ method as told here
http://forum.xda-developers.com/showthread.php?t=2432476
But everytime it shows internal error on "2 or 3 percent". It didn't worked for me. So i decided to do tot mothod.
Download tot file, dll file, LGFlashtool, drivers etc.
Followed whole process which was also described in above post. But when flashtool reached at 94 percent and mobile was being rebooted it showed error
"Fboot check"
"Fboot Check"
"Can't reboot completely"
I tried to turn of phone at this condition by waiting and then doing a factory reset by keys combination but it keeps resetting and rebooting. I searched whole internet but can't find a solution. Can anyone please help me. Because i bought this cellphone a week ago for my friend and i would not be able to face him after showing a sick phone. Please someone help .
Only download mode of phone is working, It also keeps led light on while stuck at logo.

My Galaxy S5 appears to be unflashable/unrootable, any advice?

Hi,
I recently got me a Galaxy S5 (SM-G900F) and the first thing i wanted to do was installing CM13 as I always do with my new phones. However, when i followed te steps on CM wiki using Heimdall to flash TWRP the blue bar of the downlaod mode increases a small bit, then stops and in the command promt it says something about error with finding PIT. After trying this for three times i decided to go with Odin, which I do prefer anyways.
I tried flashing TWRP , the blue bar is filling to 100% but then on the little screen where Odin usually states FAIL! or PASS! it just says RESET! and my phone is restarting. Shortly after it restarded you can see the RESET! turning to PASS!, but when I tried checking in TWRP is installed, it wasn't. I tried it again and then Odin suddenly says FAIL! After restarting my phone it says "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again". I couldnt even enter download mode anymore till I tried if getting out the battery would work. I could enter download mode again and flashed the same TWRP on my phone again, and aigain it says RESET! but after that my phone worked again. I tried flashing with another version of Odin and TWRP but same thing happened - First run it said RESET!, second run FAIL!.
I thought maybe rooting the device and installing TWRP via their app afterwards could do the trick. So i tried flashing Autoroot with Odin but it made my phone showing a screen with Samsung logo and in the upper left corner something about recovery mode, seemed to be a loop/freeze. So i took out the battery again and flashed TWRP and that solved the problem again. At last I tried rooting by using TowelRoot but it says the service is not available for my device, even though S5 is listed as a supported device.
I really have no idea what to do anymore, would be very grateful if someone could come up with a solution.
BTW: Is it possible to flash CM13 without using custom recovery by using stock recovery?
Greetings

RESET! is basically the same thing as PASS! What version of TWRP are you installing? The keis screen you got is the same as download mode. Why are you using heimdal? your idea to go with Odin was a good one. Anyways, download TWRP 3.0.2 (not 3.0.2-1 or 3.0.2-2 as they are buggy) and flash it in Odin, reboot to recovery and install the ROM you like, of course following its specific install instructions. No, you cant install a custom rom with stock recovery
Thanks for your answer, meanwhile i managed to fix this problem. Had to flash the latest Firmware because twrp (could just install the oldest version otherwise I had no option to boot into recovery at all) said no OS installed. After rooting via Odin worked like it's supposed to.
Why did I use Heimdall? Because I wanted to stick to CM-wikis instruction and they used Heimdall.

Bootlooping to Factory reset status

Hello,
I'll try to detail as much as I can to explain how i ended up Bootlooping :
I tried today to root my LG H870. (imported from Germany, according to the seller).
I followed the tutorial on xda to unlock the Bootloader on the device.
After flashing it, it launched Android the 1st time without difficulties.
I rebooted into TWRP, flashed supersu, then rebooted into Android. Problems started there, the system told me my partition was encrypted, and asked if i wanted to reinitialize it. After doing so, it's been stuck, bootlooping to TWRP, the internal partition empty.
I followed numerous tutorial on how to flash a stock ROM through TWRP, Fastboot, ADB Sideload, without any success.
With TWRP, it was always ending up saying the flash wasdone, without writing a single file in the partition.
I also tried installing stock ROM with LGUP, but once again, didn't seem to work. While in download mode, it was either telling me the phone was an unknown model, on port COM3, or that there was no handset connected.
I then followed another guide, using LG Firmware Extract and LG Flash Tool. It didn't work as expected, but, I don't really know how, it made LGUP seeing my phone correctly. I was then able to flash a stock ROM (H87010f). No error during the process.
After the LG Logo, i get now a blue screen, saying for some seconds "Encryption Progress", and after that "Factory Reset Status", with a big red "2", and it gets stucks there.
Once again, if I get into download mode and into LGUP, i get now the "no handset connected" message.
Is someone on here able to help me?
If more infos are needed, tell me, i'll try to answer!
Thank you all!

[HELP] Completely stuck in security error loop at boot. Phone is not recognized by PC

As I say in the title I have a LG G3 D855 and I was trying to root it and installt twrp but I completely screwed up.
After that I managed to go into the qualcomm bootloader and restore the phone following this tutorial https://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091, but I keep on getting security error loop.
I cannot enter download mode, therefore I cannot flash my rom again. I have tried already with the tot images from EUR and HKG, and still no improve.
Any experience/help on solving this?
Thanks in advance!
