My router is totally bricked. I've tried to unbrick w/ tftpd32/64, putty, pumpkin, serial ttl jtag, linux tftp.

The router is dead: ping is not responding, don't boot in putty (ctrl+c).

Can someone share HEX files of both bios chips (Winbond 25Q128BVFG) or boot image file ???

Unbricked router with this attachment open wrt firmware or this link http://downloads.lede-project.org/releases/17.01.4/targets/ar71xx/generic/lede-17.01.4-ar71xx-generic-wzr-hp-g450h-squashfs-sysupgrade.bin (i tried some firmwares , but it didn't succeed)
2. Read this and choose a stable firmware with REV 0 , or REV 1 to flash by system upgrade when success unbricked . (My router has been bricked , so i downloaded by phone's 3G ):
