My phone goes into a boot-loop the workaround is going removing the flex cable?

Please provide more detail to your question. It would be helpful to know what parts you replaced, which repair guides were followed, what issues you may have encountered during reassembly, etc. Without more info, I’d say you’re stuck with tearing down the phone again and double-checking all connections are seated correctly, that no wires have been pinched or shorted against the case or other internal parts. Good luck, _rs

Just gave a refund instead forget it.
