Do I have a bad radio?

[Stranyer]

Hi everyone, I've the M8 International, but I'm having some issues with signal, and I can't get 4G working on it in fact 3G would barely work.

Could it be that I've an old radio?

I'm in Argentina, Buenos Aires. 4G is working just fine in others phones. (Also, while I was on Canada I had the same issue)

I don't know if this will be of any help to you guys, but this is my baseband.

Thank you!

Are you S-OFF?

If your carrier has their own version of the M8 you can try flashing a firmware.zip that has the radio that was released with their lollipop update. That might improve your situation.

If you're running on the pure international firmware, that's just an overall generic radio update. Carrier updates have their own tweaked radio that they test and adjust for best network performance (in a perfect world).

Thank you for your answer, yeah I'm S-OFF. Also, there wasn't any official release from my carrier for the HTC, they don't even sell it. But others phones like the Moto X, or the Xperia Z1 works just fine, getting over 20mb of download, while I can't even make 1mb.

Is there anything else I can do? A place where I can download the latest radios?

There is a thread with Radio updates, but the original 1st post hasn't been updated in a year, but users have posted links to other radio version...

Unfortunately it's not in one convenient list, you'll have to search through it.

Flashing radios has the risk of a brick, so be careful and make sure you are 100% sure that its compatible with your GSM phone and you are well aware of the steps and risk.
