update: seller (which is a professional refurbisher) says that all his refurbished pixels are american/verizon and he used to flash the global bootloader via JTAG, but since the pixel 6/android 13 (pixel 6 with android < 12 can, then they patched it with some antirollover) it can’t be done anymore. He says that nobody cares about bootloader unlocking and I’m literally the only one out of thousands of customers to have noticed the issue. He says that there’s a way to jtag the global bootloader onto the verizon pixel 7 and allow bootloader unlocking but it will have a permanent “software tampered” warning on boot and it can’t be locked anymore. Don’t know how much true that is.
