[Q] Stuck at black screen - G2 Q&A, Help & Troubleshooting

Hi to all,
I'm an HTC User but, my friend has some problem with his G2 from Videotron in Canada. He rooted the phone and tried to install a recovery. using the AutoRec method... Now, he's stuck at the screen on the attached pic. fastboot commands work. ADB commands don't work... I've been looking for a few hours and I can't find anything with the same problem or a solution... If anyone can help or point me in the right direction, it would be greatly appreciated!

Sorry... Here's the image!

I believe that happened to me when I installed a kernel that wasn't for my device...

Remember what you did to slove the problem...?

Bootloop issue! Please help! Fastboot mode started...

I tried to get CM11 on my LG G2 on Bell Canada's network and I really messed it up. I can no longer get into recovery, adb doesn't see my phone, but download mode works (though I have no idea how to use it). Phone boot loops to little rows of words at the top of the screen:
[650] Fastboot mode started
[700] udc_start()
Please, what can I do to fix this phone? I need a simple tutorial for a total noob like myself.
Thanks!
Secondly, is there any way I can get CM11 on this Bell phone? I don't like LG's skin...
Please help anyone?
Not even one reply? I'm sinking here guys. Please help a brother out!

HELP!! plz help im dying with me LG G2 D802

plz help me anyone out there urgently, :crying: I was just flashing stock firmwire on my G2 D802 32GB varient using the .kdz method suddenly the USB cable got disconnected and the Download partition was gone then i only had fastboot, no download or recovery mode.
then i tried to get back the download mode by flashing laf.img but some error occured and now even fastboot is gone
so basically my phone is stuck in LG Logo and NO FASTBOOT, NO RECOVERY or NO DOWNLOAD and windows pc can't even recognize it when connected by a USB cable
plzzzzz help me get out of this pathetic situation im dying here all day without any help pllllzzzzzz any help is greatly appreciated. Thank You!!!
Only service and changing motherboard can help
Oh SH... sorry but your phone is dead...
sorry but what is laf.img? Don't panic yet maybe not all is lost... sometimes **** can get scary but modern hardware isn't bricked easily
EDIT 1.1: did you try this? http://forum.xda-developers.com/showthread.php?t=2681089
I should mention I have no idea what fastboot is.
Just found out laf.img is something to do with partitions... very dangerous if you flash wrong partition layout, did you flash correct variant?
EDIT 2: more options, including holding ALL buttons at once: http://forum.xda-developers.com/showthread.php?t=2476972

Windows and /or linux(ubuntu) don't show any signal(beep, new device, error) ?

[Q] Help needed. Bricked LG G2, when google didn't help!

Good day fellow XDA users!
I've been playing with my old LG G2, and as you could have guessed - bricked it (while trying to instal Android L ROM)
The problem: The phone is not booting further the LG logo.
I've tried:
1. Doing a hard-reset, didn't work. After getting to the hard-reset screen - I double-confirm the reset and then nothing happens (waited for about an hour and a half).
2. Entering download-mode, didn't work. It shows the "download mode" logo but nothing happens.
3. Connecting to PC, fast-boot, adb of LG Tool can't "see" the device.
Any suggestions?
Thanks in advance
Anyone?
Your phone boots in fastboot?..or it's only stuck on LG logo?..if you can boot in fastboot then there are some threads around here about how to recover...but if you are stuck at LG logo i don't know.. I hope somebody more experienced will help you.
Nope, I didn't manage to get it to load fastboot.

Hello, sorry it took some time to answer, but here (original post can be found here http://androidforums.com/threads/he...when-google-didnt-help.900687/#post-6874443):
FIXED!
I followed the steps and it worked!!!
1. http://forum.xda-developers.com/lg-g2/general/lg-g2-unbrickable-fix-real-hard-brick-t2904404 this liknk helped connecting it to PC.
2. http://forum.xda-developers.com/showthread.php?t=2582142 this link helped me flash the partitions, well actually not, because I didn't have a linux machine next to me. So I found this http://forum.xda-developers.com/lg-g2/general/unbrick-lg-g2-qhsusbbulkqualcomm-9006-t2939627, which is really a walk in a park, just download and run the file.
Anyhow, now my phone works!
Special thanks to

Rebooting to Bootloader doesnt work. ZUK Logo appears and seems like frozen

Hello Guys,
i have a Problem with this Handy. It was stuck in a Bootloop for two days then i tried to flash with a cm rom but appearently it didnt worked and messed up the Fastbootmode. Today i successfully restored my Z1 with the QPST Software but the Bootloader still wont work. Can someone tell me how to fix this? Because i want to install a other rom (current rom displays a watermark like thing on the screen).
Thanks and have a nice day

well i just followed a tutorial in youtube since it didnt worked with the adb sideload.
i just connected my z1 while holding volume up so that the software can recognize it. Then i loaded the qualcomm firmware and selected the xml of the tutorial with a recovery.img. After that i just clicked download and it worked again.... except i cant get to the bootloader. My thoughts are that i somehow ripped/deinstalled the bootloader.
