D802 - Stucks on LG Logo -No Recover, No fastboot and No Downlaod Mode

Hey guys,
I have a LGD802 32GB it stucks on LG Logo and a green/blue LED is blinking. I can't get into Recovery or Download Mode, nor fastboot is working. Only thing what I can do is to push all buttons and get into the IMEI menue. Don't think this can help me anyway.
A few times ago the LGD802 only shows fastboot mode and so i followed the steps discribed in many threads.
fastboot erase recovery
fastboot erase laf
fastboot erase boot
fastboot flash recovery recovery.img
fastboot flash laf laf.img
fastboot flash boot boot.img
fastboot reboot
after that it only stucks on LG Logo.
I also tried the flashTool 2014 method, but phone will ne be correctly recognized by the OS. False Driver?
The Flashtool stops at 4%
Anyone can help me?
@DarkD1988 If the phone only showed fastboot mode then it might also have been the kernel that caused that,
does it says something on 4%?
Try to find the drivers or manually install them with device manager and see if it might works then.
Did you flashed the Lollipop rom?
Hi,
The Flashtool only starts if i use the diag driver (manually chosen).
With the automatically Installed Driver (USB Device Driver) the S/W Upgrade wont start 0%.
Yes Lollipop was flashed but after that the device became a hardreset.
At the Moment I cant get to the fastboot.
Do you know which driver is the correct one?

[Solved] Help soft bricked phone and fastboot not recognizing device

Hello all dear members. I am new to flashing. I was rooting my yureka and successfully rooted it after flashing twrp recovery. but then I unlocked bootloader which flashed all internal memory(I know it was a bad move and it flashed everything). Now phone is struck in boot loop and also unable to boot into recovery. My computer has all the drivers installed because I was able to flash it before. But now when I connect it in fastboot mode, in adb or fastboot command it is showing waiting for device. I am in windows 7 x64. Please guys help.
This command worked for me.
fastboot -i 0x1ebf boot <recoveryimagefilename.img>
I was able to install stock recovery and phone restarted normally

- flash with miflash
- repartition - https://forum.xda-developers.com/redmi-2/how-to/how-to-erase-partition-table-redmi-2-t3520410
- fastboot flash direct method - https://forum.xda-developers.com/redmi-2/how-to/error-resolved-t3324791
any suggest?
Thank you in advance
1.try miflash and flash rom according to your device... and look at progress (some doesnt flash just shows and finish fast) then try with another version of miflash, flash it it will take few minutes
2.if u r still in bootloop after these all ( i faced so many times dnt wrry )
then flash twrp, fastboot boot twrp...
flash any custom rom
I had the same problem, flash twrp and install a custom rom, it worked for me
Tried this method.Worked for me
1.Download the official fastboot rom from the official miui site
2.Check whether ur device is recognised or not
3.Install minimal adb and fastboot
4.Type these commands
fastboot flash system system.img
enter
fastboot flash boot boot.img
enter
fastboot flash recovery recovery.img
enter
fastboot flash cache cache.img
enter
if u want to remove all userdata then
fastboot erase userdata
fastboot flash userdata userdata.img
fastboot reboot.done!!!
I have same issues, when I unplug the charge the phone restart with bootloop, it is on, off and on and off, i cant go to recovery mode if not i charge, i just can go to fastboot mode if I don't plugged in my charge. And I can't go to bootloader menu's

zuk z1 bootloader locked when twrp installed

what i messed up?
i have installed custom official cynogen14.1 rom and twrp recovery. everything was working fine.
but i messed up with bootloader. I have locked oem from fastboot mode without enabling option for oem unlocking in developer settings.
Now as my phone have custom rom and twrp installed it went into bootloop and only shows zuk logo and again restart.
What i diid till now?
i have opened backcover so that i can turn of bootloop and phone by disconecting battery.
I can enter into fastboot mode by pressing vol.+ and vol- buttons sumultaneously and connecting usb cable.
But i cannot unlock bootloader as it says unlocking bootloader not allowed. I have tried device specific commads like "fastboot -i 0x2b4c oem unlock" and "fastboot -i 0x2b4c oem unlock-go" but nothing works.
i have stock recovery image but cannot flash while bootloader is locked.
i can enter into adb sideload by following method:
by loading stock recovery by typing "fastboot boot recovery.img" (this does not work with twrp as it says signature varification failed)
and then selecting apply update >> selecting apply fron adb
this much i can do does anyone knows how to recover from such a state.
please help me or my phone will be a waste.
is there any way to install stock recovery i think phone will boot properly if i managed to install stock recovery.
