can't re-unlock my bootloader plz advice.

[komilAD]

My bootloader is re-locked. Now i want to unlock it again but it always gives an error stating "Failed (phone is already rooted)". I have tried with flashtool and cmd-fastboot method but the result is always the same. In service menu bootloader unlock allowed says yes. Is there any alternate way to unlock bootloader once again? I can't seem to find this error on Google so am really confused what to do.

Looks like i am not the only one with the same error.

Since no one was able to find solution so i was trying tons of things and finally i figured it out by myself.:smileysmileythumbsup:


Here is what i did, i used another computer.:smileytongue:

Ok so I think there were two reasons why it keeps getting errors: 1) either my high end pc wasn't supported or 2) it required same pc from which i had previously unlocked the bootloader.:smileyhappy:
