Does anyone have US bands to flash for the Qin F22 Pro? I’d like to make a Qin F22 Pro work in the US

There is currently no such thing. it either works out of box or doesn’t

Writing in Apex is one of the hardest things. only chinese are good in it. if you want someone should rewrite them modem stuff - it’ll cost you a few grand…

Is anyone working on it?

I once got ahold of an F22 that works in the US. I pulled a full partition backup. If anybody thinks that could help them, I could send it

6

naaaahhhh… I don’t believe it.

Other than that, all F22’s work in the US, but they are problematic. I don’t think anyone wrote bands for it. It requires a buuuunch of time and knowledge in hardware, let alone software.

IDK. I know a guy in Brooklyn who had an F22 for a few months. He never complained about service issues. I’ll ask him

Can you send it in?

Send what in? The partitions? Which partition do you need?

The guy just got back to me. Here’s his text:

Good morning, hope all is all for it I really apologize for being unavailable the past few days it was very very crazy by me. So yes, the f22 pro, even though you don’t need to change any IMEIs or anything like that, it’s still gives you significant blind spots service in New York City meaning the snake rarely do I have five bars of service and it often doesn’t work with the slightest environmental service compromises are happening. Hope you find this information helpful have a good day

Here’s an F22 I’ve seen that works with Verizon in Lakewood with VoLTE, but not with T-Mobile. In Brooklyn, Verizon service is spotty.

Those aren’t the USA bands! :roll_eyes:

That’s not fully true.
Band 5 is completely compatible with Verizon in “most” of the us.

One band is all it takes for the phone to work as long as its available in that area.
Even on the american flashed qins the only bands that actually work are 4 and 66.

4G LTE USA BANDS:

  • Band 2 (1900 MHz)
  • Band 4 (1700/2100 MHz)
  • Band 5 (850 MHz)
  • Band 12/17 (700 MHz)
  • Band 13 (700 MHz – Verizon)
  • Band 66 (AWS – extended Band 4)
  • Band 71 (600 MHz – T-Mobile)

The f30 has these: 2, 4, 12, 13, 17, 66, 71

21

What are you saying?
A phone can never be connected to more than one band at the same time. (It has all those bands for best coverage)
Thats first of all.
Then, those are the bands on the F30, correct, however when flashed on the f21 to make it work, it only connects to bands 4 and 66 . You can check yourself with an app called lte discovery.
