Qin F21 Pro General Thread

Phone doesn’t turn on and I can’t flash sp either

Autobooter fastboot?

Didn’t try thanks I’ll give it a go

Doesn’t the phone need to be powered on to go into autoboot?

Nope no good

I think it’s supposed to be off.

Is this referring to the F30?

Yes

Well the F30 was out a lot before September 2025.

The service became really bad again and I hope to reflash it soon. It keeps on connecting and reconnecting and it’ll say server unreachable even with all bars… the problem is that I missed some important sms messages and phones calls. I use google messages for texts. Any way I can still get the texts and see the missed calls that never came through?

Seems like from what you described CDMA less isn’t enabled reflashing won’t help
Regarding getting your messages you missed I do not believe there is a way

You can usually get them for 3 or 4 days after if the messages wern’t delivered

How?

They should come in automatically
