but it tells me to connect the phone
what can i do please help me

i'v3 installed OMAP driver and flashed correctly the phone. but now it is in boot loop with the lg logo that appear and disappear

Remove the battery. Put the battery back, hold volume down + home+ power, release power after lg logo appears. You should see an android logo and a progress bar, wait until it finishes and it will automatically reboot. Now it should boot.

Yeeeeeessss! Thanks!!! But i would like to install a better rom: could you suggest me something? Could i flash a custom recovery? Could i unlock the bootloader?

[SOLVED] Bricked device

After flashing stock images I think the bootloader somehow got screwed.
When I boot into bootloader, it has the robot pic, saying downloading, do not turn off target.
It has the normal info too, saying bootloader unlocked etc, but I cannot switch with the volume key whether to go into recovery mode or anything.
When I try to tonnect with ADB or fastboot its waiting for device forever.
Otherwise it can boot into the OS normally, but even from there I cannot reboot it into recovery mode - again, waiting for device forever.
That's "odin mode". Hold both volume up and down + power and don't release until you are in fast boot.

It was booting in Odin mode even with the 3 buttons pressed.
However, I succeded booting it into fast boot with fastboot - had to reinstall ABSOLUTELY ALL the drivers on my system then fastboot finally succeeded connecting.
Tnx anyway

Verizon LG G3 won't go into recovery mode.

Finally rooted my Verizon LG G3 but now I can't get it into recovery mode. When I press the volume up + power button it goes into some download mode and a firmware update screen shows up but it's stuck at 0%. I tried going into recovery mode from quickboot but when the phone restarts, it just says "secure booting error" in small letters in the top left side of the screen and power offs. I think my phone is bricked. Any help would be appreciated

Click to expand...
Click to collapse
Yeah same thing happen to me as well....
If your phone was bricked, then it wouldn't boot. It just sounds like you can't get to recovery. This typically happens when you attempt to install a custom recovery either the wrong way or on the wrong update for the method. Need more details for further assistance.
What update are you on? Software Version, not just Android version.
What method did you use to root?
Did you try to install a custom recovery? If so, how?
Does it still boot to the OS?

Cant boot into fastboot or flashmode, device not recognized

Hi,
today I wanted to flash a new firmware on the M4 Aqua (E2303). But I cant come to Fastboot/Flashmode. In Windows a message comes, which says that the device get not fully detected. On the device manager I get "device not recognized" and the hardware id is USB\CONFIG_DESCRIPTOR_FAILURE or USB\DEVICE_DESCRIPTOR_FAILURE . But when I boot into the system, the usb connection works correctly. Also when I shutdown the device with connected usb I get sony mass storage usb. I also followed the quide the, but without luck: http://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed/. And drivers are for sure installed (also installed at least Xperia Companion)
I did...
... adb reboot recovery -> device not recognized" with black screen, reboot (sound like because usb disconnect, but screen is still black), device hangs and it is a odyssey to get it boot again with long hold power and/or plug the reset hole!
... power off -> hold volume down + plug usb -> "device not recognized" and black screen or sony logo... sometimes I had shortly a blue screen, but than the device reboots and than hangs like on adb reboot bootloader
... power off -> hold volume up + plug usb -> device shuts down
... power off -> holt volume up (and also a try with vol up+down) + power till the 3 times vibration comes. but after that it also not boot into flashboot/fastboot.
... wiped the data/internal partitions from recovery -> same like before
... boot into recovery and selected reboot into bootloader -> device hangs
I can only boot into the installed Stockrom and into the twrp recovery.
Any idea where to get the stock rom in zip format to flash it over recovery? Or is there any app to flash the rom from the booted system with root? Anything else?
No idea?

Happened to me too recently. Using an older version of Flashtool solved it for me. İt was 9.18 I think.
