Hello ,
My h950 running 5.1.1 PR rooted would not open apps , i restarted the phone and it got stuck at lg logo . i pressed both volume keys and power button but nothing happened . i then pressed volume down and power and the phone restarted to fastboot mode . it gets detected by "fastboot devices" but "fastboot reboot" does not work .
i pulled the battery cable , pressed power and it booted straight to fastboot mode .
press volume up and plug in pc cable , it boots to download mode . if i remove the cable , it goes to fastboot mode again
any ideas ? i would like to avoid a factory reset with kdz .
please help

you'll have to ask for someone to backup up partitions or extract them from the KDZ and flash them directly through fastboot.
Lucky you you have FASTBOOT and not QHUSB_BULK alias Hard Brick alias QUALCOMM 9008

finally i long pressed power button approx 5-6 min and my phone restart normally.
problem solved.moderator plz close the thread
What can I do to unbrick it?
The boot loop is because I tired to fix gps with this method:
"Actually... after rooting it, go to System folder and edit Build.prop (read-only!) and add a line in the end of the file to look like this:
dalvik.vm.stack-trace-file=/data/anr/traces.txt (already exists)
dalvik.vm.execution-mode=int:fast (the line to add)"
And the result is boot loop .
I can do hard reset but nothing happened.
I can go to fastboot.
I can't flash it with LG flash tools.
Please help me.
Bumping this thread. I've got LG L Bello d331 and I bricked it trying to update it to lollipop manually. It got got stuck on the beggining of the update and I removed the USB cable. Since then the phone goes only on fastboot mode and nothing else.
Does anybody have a clue on how to resolve this issue? Any way I can flash a rom through fastboot mode?

Maybe you can try to format userdata and cache via the fastboot command:
Code:
fastboot -w
Try this at your own risk. Your data will be lost after that.

do you have tried this?
phone without battery (reinsert batt when beep its heard), press vol down or vol up wile connecting to pc, now look for device manager: have mtk usb port in com devices? if yes you have a hard bricked d331 (like me)
if not: you have unknow device (need install mtk drivers)
if not 2: you have a preloader mtk, in this situation you can use a Lg flash tool in fastboot mode for upload firmware kdz
Hi!

Steps:
- Install the correct drivers and ADB
- Copy the image files (system, boot,recovery) to your ADB folder on PC.
- Turn your phone on in fastboot mode (press volume down button + power button at same time) When the Acer logo appear connect the phone to PC.
- Now open a command line in your adb folder and type these commands:

dd if=/storage/sdcard1/system.img of=/dev/block/mmcblk0p16
"this will a long procedure because the system is 1,2GB"
finally do a factory reset and reboot

First open the phone's bootloader because the boot image in backup not the original one. Unlock the bootloader with adb or replace the aboot.img from the rooting thread, restore my backup and everything will work

I had the same problem when I first time rooted the phone. This comes sometimes when you unplug the USB cable in bootloader mode or with adb connection. Why power + up and down? Just hold the power for 15 sec (at black screen) after try turn on. If doesnt work, put the phone to charger and leave 3-4 hours and try again. This always work for me.

U10 is same times duficult to flash recovery.
Download CWM recovery, boot in bootloader ( fastboot - must say in UNLOCKED ), use ADB and write :
fastboot flash recovery cwm.img ( if the image name is cwm )
Than don´t reboot, press vol + and power at same time, hold it and wait, when power off release only power key, like this image will be save for sure.

Am i picking the right rom for this !
Which rom is the safest to flash for my model ?
Yes I have the Chinese model aswell. Its the correct one
I have another problem , my windows fall apart so i installed it again
And now i dont have drivers
Since I cant boot to enable usb debugging
Which drivers should i install to recognize a fastboot device ?
You don't need to boot the phone.. Hold VOL UP and DOWN and POWER at the same time. It will boot into Fastboot. Windows should automatically detect the phone.
