Hi all,
first of all - sorry for my bad english.
I have the following problem with my nexus 7:
the device is rooted and has the clockworkmod recovery installed, the Android version is 4.1.1.
My Computer stopped to recognize the tablet when i connected it, and it is not listed in the device manager anymore.
I tried different USB-ports, cables and even computers with no result, but OTG with Stickmount still worked.
So i tried to install a rom via clockwork mod, but the installation process aborded.
When rebooting the device stucked at the white google logo and still does.
I can go into fastboot mode but if i choose "recovery" i will get back to the google logo forever again.
I found this thread (http://forum.xda-developers.com/showthread.php?t=1773431&highlight=no+usb&page=2)
with instructions to flash the factory image via fastboot mode.
Now the fastboot command from the console shows also no result.
But i can´t install the driver, because my tablet isn´t recognized by my pc in any way evon not listed in the device manager.
Any Ideas?
Hello everyone!
My LG G2 D802 is bricked!
Two day ago I tried to flash twrp recovery in order to install some custom roms.
I used the autorec method, but the phone now is stuck on the LG logo.
I can boot in download mode (vol+ and plug usb cable) but the LG MOBILE SUPPORT TOOL does not work !
I've also tried the OFFLINE method but it still does not work (seems the usb is not properly connected, but the drivers are just fine)
I've no more fastboot (think i messed up with something by using adb fastboot because i flash a bad recovery.img) and now
if I try to boot into recovery (by pressing vol - and power) it says: secure booting error - error: Boot Certification Verify! than the display turn black and if I plug the USB cable windows says that I need to format the disks...
I've also notice that in the usb devices there is a QHSUSB_BULK which is not proprely installed, so i tried to use this method :

but Ubuntu is not able to detect the device!
What i've to do?
Thank for suggestions
EDIT: ok, problem solved using ubuntu!
Ok good u figured it out. I was gonna suggest fastboot. Reflash recovery. That worked for me. When i have black screen and white letters top left corner of screen

Hi, I just bought an LG G2 D802 20B Model a couple days ago, yesterday I wanted to downgrade to 4.2.2 and I ended up bricking the phone.
The phone is non rooted, doesn't have any custom recovery, and not recognized by adb even though i installed all the drivers ( koush drivers, PdaNet, Lg drivers ...)
At first I flashed with .kdz file and it ended in bootloop, I tried to factory reset but it doesnt have any effects with the stock recovery it only shows the green android bot and blue progress bar and then restart in 3 seconds and reboots to lg logo and start looping.. After a restart the download mode didn't work anymore it showed me fastboot error, I searched for the tutorial that actually worked and I flashed with .tot method but there is still bootloop and the download mode is stuck at the image attached. The phone is not recognized by neither windows or ubuntu therefore I can't use adb to fix the partitions.
Can any body provide me with a solution? The phone is still new and it will be a shame if its transformed to a brick in 3 days :crying:
Hey..hmm i think thats how download mode it is...so did you tried to flash again a firmware?

Thanks for your reply, however the phone is not recognized on windows neither on ubuntu therefore this tutorial can't help ...
I am in the exact same situation.
Mine is a D802 32GB Hong Kong model. I stupidly ran AutoRec which soft-bricked my phone. Managed to get Download Mode working, then flashed 20C and 20B which bootlooped. Then I attempted to flash 10B, which got me into this exact state:
Download Mode not working (only shows "Download Mode", does not go to firmware recovery screen, not detected in Win/Linux)
Factory reset (Power + Vol Down) can go to factory reset screen, after factory reset, still bootloop.
Once in a while, I also get the Android icon which then disappears after a few seconds and goes to LG logo again.
If I plug the phone in and do a factory reset, Windows detects the LGE AndroidNet modem, and Linux will detect cdc_acm USB Abstract Control Model driver. Flash Tool and LG Mobile Support seems to detect the phone and attempt to flash, but the phone restarts after a short while.
I have no idea what else to do
Hi,
I have a LG G2 F320k.
I can not go into recovery or fastboot mode or download.
I connect the USB to the PC and this is not recognized.It does not appear in Device Manager.
The PC does not detect it when you turn the phone, the drivers are not detected..
Two days ago fastboot mode through loaded all * .img. The last one recovery.img. From that moment the phone has not restarted and brought back into fastboot mode or reocvery mode.
In ubuntu neither detected.
When I turn it on only the LG logo appears and restarted.
Can you recover?
I disassembled the phone if I could do the following tuto, but my phone board is different from the tuto:
