Installed wrong rom firmware

I installed the wrong firmware on my chromebook now my chromebook has trouble boot and other issues

If your Chromebook is bricked, you will have to flash the correct firmware for your Chromebook using a suzyq or CH314A programmer.

It booted into chrome os but mrchromebox script doesn’t work any more

Without knowing exactly what you did, it’s very difficult to know how to assist you.

So i was returning to stock chrome os but i did the firmware rom for BLUEBIRD-STOCK but my Chromebook is RELM-STOCK

Because i was not paying attention

So you can boot ChromeOS? Then just use the recovery image for RELM and do a full recovery?

Yes but the HWID Is incorrect and it wont accept when i try to change it to the right one
