It was stucked on LG Logo with the word "Security error", I hard reset it but nothing, when I decided to reflash it it failed and probably dead... Is there any chance to get this phone working again or to unbrick it via JTAG or something else..

[Andosonson]

I THINK IT IS NOT COMPLETELY DEAD, I KEEP TRYING TO MAKE A BOOT REPAIR I STILL GET THIS ERROR <Writing u-boot...Failed!>
WHAT MORE CAN I DO.. PLEASE HELP ME

Try to re-flash the phone with the latest Software version. If the problem is the same, most likely, this is HW issue (problem with phone's eMMC flash chip).

If only i could write firmware? The only thing i can do is trying to repair boot. Anyway I used the last version of Octoplus LG and i got the same error.
My question is, What that mean Erasing u-boot... u-boot not erased. Trying to skip. Writing u-boot...Failed!.
I guess octoplus brick my bootloader

Erasing u-boot...
u-boot not erased. Trying to skip.
Writing u-boot...Failed!

This part of the Software log means that phone is not responding on Software CMDs. Software tried to erase u-boot partition and when phone have not responded, it tried to write the partition without erasing and it failed as well.
In most cases such problem occurs, when device has HW problems (problem with flash chip).

Ok, I understand, previously phone was working fine, after a hard reset phone stcuked on "LG logo security error", I read about such error in some forum, may be it can solve only via JTAG.
