No, there are never any date for any device that may/may not be supported.

thanks for answering master, could you give me a suggestion what can I do to recover the imei of the equipment, I arrive at the workshop to remove frp and at that moment the light went out and the team just stayed in fastboot with the phoenix dc tool I could revive it but with that detail that the imei remained in 000000000000000

Excuse me my bad English is that I am from Venezuela and I am helping with the google translator

There is no actual for it unless maybe after board software flash, HCU may allow repair it, then can fully update it with stock rom.

I already tried to do that and hcu gave me an unknown chip error
