I thought my pixel was bricked after a bad flash of a custom rom... I ended up with no os. I could still boot into recovery tho and eventually, after hrs of banging my head against the wall got it to accept a flash all command. I believe thats what saved me honestly. But i really dk i actually woke up the next day after staying up the whole night trying to fix the no os problem to my pixel working perfectly. Super crazy. But i understand your pain... It doesnt boot into recovery at all??
