Fiash via adb:
1. Download the radio.img above
2. Put the radio.img file into your ADB folder
3. Open up command prompt and copy and paste the EXACT lines
4. adb push radio.img /storage/sdcard0/radio.img

Some advice for people with the ASIAN version of the HTC One M8 (aka 2.5 Ghz Krait phones).

I have tested the following radio's and they do not work: ATT, T-mobile, WWE, GPE. I have not tested the dev. edition radio yet. My phone has S-off and Super CID.

When you flash any of the above radios your phone will boot fine but it wont connect to a tower. After five minutes of trying to connect, the phone automatically reboots. To restore your phone you have to reflash the Taiwan radio (HTC__621 / 1.54.709.4).

If anyone with an Asian edition phone wants to double check my experiment, feel free to. The risk of damage to your phone is nil.

Will flashing the AT&T radio open up the missing bands on the T-Mobile M8?

Sent from my HTC One_M8 using XDA Premium 4 mobile app

I flashed the AT&T radio on my T-Mobile M8 and got excellent results. On the T-Mobile Radio I was getting very spotty lte at my house, but since flashing the AT&T radio I have not experienced that spotty signal and data speed.
