Default [Q] wrong relock

well my nexus 7 was rooted for a long time and it was always a good tablet but one day i played around with it after an update i didn't tipe fastboot oem unlock but fastboot oem lock so i locked my bootloader by accident and with not even knowing that i did this mistake

but without a stock recovery.img, no stock system pretty much nothing stock but with twrp recovery and paranoid android on it, when i tryed to go to recovery with no error but it couldn't mount enything

when with the sdk tools i tryed to format everything and that even worked

then i looked at my bootloader that it was locked so i tryed to unlock it with no success, and pretty much the other 20 times , and i even tryed tools like N-Cry, well still (it went fine but going on with a black screen and bootloader still saying locked maybe because no system is there so no ADB mode to go in) or (saying unlocking... in the upper left corner of the bootloader and doing nothing else)

so my question is if there is a way to fix it
