So my iPhone hasn’t got imei, i cant activate it, is there any tool do this without imei? Thanks

No. There is no way you can bypass activation without an IMEI number. The baseband IC is most likely busted and it isn’t a DIY fix unless you’re familiar with reflowing and reballing logic boards. Check out this thread here: U601 RF Replacement iPhone 5 Baseband Chip IC U16X I cannot verify if it’s the same chip they use from the iPhone 5 to the 5s.

Just update to latest version and then run checkra1n. after that there are lot of softwares to jump without activation
